Adverts and signs

Planning permission is not normally required for a small sign, for instance with your house name or number on it.

Learn more about adverts and signs.

You may need to apply for advertisement consent to display an advertisement bigger than 0.3 square metres, however, and the planning regime for larger, professional adverts, signs for businesses etc. is complex.

Domestic adverts and signs are not normally subject to building control, although, if a lit sign, any electrical work would be. In all cases signs must 'be kept in a safe condition'.

An illustration of an external heat pump

Air source heat pump

Since December 2011, the installation of an air source heat pump on domestic premises has been considered to be permitted development, not needing an application for planning permission, provided specified limits and conditions are met.

If you live in a listed building or a conservation area you should also contact your council to check any local policy.

Building regulations will normally apply to installing an air source heat pump.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1 (Section 6, Page 45).

Air source heat pumps transfer heat from the air into a building to provide electric heating that generates hot water which can be used for space heating and/or hot water.

Barbecue

Many kinds of buildings and structures can be built in your garden or on the land around your house without the need to apply for planning permission.

There are, however, limits and conditions which must be followed, and in some circumstances, you will need to apply for planning permission.

Building regulations will apply if your installation involves carrying out electrical or gas works in your home or garden. You should take care that the installation is safe.

You may wish to use an installer who is registered with a competent person scheme or seek approval from a building control body. If you are unsure about whether you are required to comply, you may wish to contact your local building control body.

An illustration of a white CCTV camera

CCTV

Planning permission is not normally required for installing a CCTV camera, though if you live in a listed building or conservation area you should check with your local planning authority.

Building regulations do not generally apply but you should take care that the installation is safe, and the fixed units are stable.  However, if your installation involves carrying out electrical work in your home or garden, you will have to follow new rules in the building regulations.  You may wish to use an installer who is registered with a competent person scheme or seek approval from a building control body. It is advisable to contact an installer who can provide the necessary advice.

An illustration of a conservatory

Conservatories

A conservatory is treated the same as any other extension under planning regulations, regardless of the materials used.

There are conditions and limits to what is allowed without the need for planning permission, and these apply largely to the dimensions of the proposed addition, its position on the house and its proximity to your boundaries.

The permitted development allowances described here apply to houses and not to flats and maisonettes.

A conservatory built with a floor area of no more than 30 square meters is normally exempt from the building regulations, provided that:

  • The conservatory is separated from the building by external quality doors, windows and walls;
  • Any glazing and fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales). Read the Approved Documents.

Any new structural opening or the increased width of the original opening between the conservatory and the existing house will require approval.

A badly designed conservatory can be a huge energy drain for the house as a whole. Correct insulation is vital for preventing avoidable heat loss and consider an all-weather roof..

An illustration of decking next to grass with paving stones

Decking

Putting up decking, or other raised platforms, in your garden is permitted development, not needing an application for planning permission, providing:

  • The decking is no more than 30cm above the ground
  • Together with other extensions, outbuildings etc, the decking or platforms cover no more than 50 per cent of the garden area.
  • None of the decking or platform is on land forward of a wall forming the principal elevation.

In some areas additional limitations may apply. If you are unsure contact your local planning authority.

 Find your local planning authority

The permitted development allowances described here apply to houses and not to flats and maisonettes.

Building regulations should be assumed to apply to every deck structure requiring planning permission.

If you are unsure about whether you are required to comply, you may wish to contact your local building control body.

An illustration of a dormer window

Dormer window

Whether or not you need planning permission for a dormer window or roof extension depends on several factors outlined in our loft conversion advice.

Building regulations approval is required to convert a loft or attic into a liveable space.

An illustration showing a car on a driveway next to a dropped kerb

Dropped kerb

A crossing across a public footpath or verge for your vehicle to gain access to your property from the highway is known as a dropped kerb, crossover or vehicle crossing.

You will need to make a specific dropped kerb application for a domestic vehicle crossing licence to your local authority through their website.

Don't forget to consider utilities when planning your project.

Building regulations do not generally apply. Work is usually carried out by the local authority.

However, you will need to make sure that any alterations do not make access to the property any less satisfactory than it was before.

A close up illustration of a wall mounted electric vehicle charging unit

Electric vehicle charger

If your home has off-street parking it is likely the installation of a domestic electric vehicle charger will fall under permitted development rights. As such, no planning application is required before the installation begins, provided it meets the criteria.

Planning permission is usually required for:

  • On-street parking
  • Conservation areas  
  • Listed buildings
  • Areas where the installation of electric vehicle (EV) chargers is restricted  
  • More than one upstand per parking space.

Building regulations approval is always required when installing an EV home charger and a competent and reputable installer should be used. There are specific processes related to notifying your local building control authority of a new installation.

Electric cars are better for the environment than petrol and diesel cars as they produce less emissions. To encourage motorists to switch to electric powered cars, there are various incentives available, such as grants for tenants or homeowners to help buy and install a charge point on a property that has on-street parking. .

An illustration of an isolated single story extension

Extensions and additions - detached

You can often extend or add to your house without the need to apply for planning permission provided you meet set limits and conditions.

The regime for what is allowed without planning permission applies largely to the dimensions of the proposed extension, its position on the house and its proximity to your boundaries.

You will also need to apply for planning permission if more than half the area of land around the ‘original house’ would be covered by additions or other buildings. Learn more about extensions.

NOTE: The extension featured here is for illustrative purposes.  

Visit the Extensions Mini Guide for detailed information
The permitted development allowances described here apply to houses and not to flats and maisonettes. Visit Planning Portal for information relating to extensions for flats.

Advert: A planning consultant may help with the smooth running of your project. To find an accurate consultancy quote, explore Studio Charrette's calculators.

Building regulations generally apply if you want to build an extension to your home.

However, a porch or conservatory built at ground level and with a floor area of no more than 30 square meters in floor area is normally exempt, provided that any glazing and any fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales).

Learn more about extensions.

Read the Approved Documents.

Using energy efficient glazing is just one way of making an extension greener.

A close up illustration of the outside wall of a house

External walls

You do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting your house.

If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

If you live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads, you will need to apply for planning permission before cladding the outside of your house with stone, tiles, artificial stone, plastic or timber.

The permitted development allowances described here apply to houses and not to flats and maisonettes.

More information

Learn about the planning rules for external walls.

Learn about wall insulation.

Safety advice

If you want to re-render or replace timber cladding to external walls, the building regulations may apply depending on the extent of the work.

Where 25% or more of an external wall is re-rendered, re-clad, re-plastered or re-lined internally or where 25% or more of the external leaf of a wall is rebuilt, the regulations would normally apply, and the thermal insulation would normally have to be improved.

An illustration of the corner of a house roof showing the facia and the wall

Fascia

Maintenance of a fascia such as replacement or painting generally does not require planning permission.

However, if you live in a listed building or designated area (conservation area, national park, area of outstanding natural beauty, etc...) you should check with your local planning authority before carrying out any work.

Safety advice

The replacement of any fascia board or soffit will not normally require a building regulations application to be submitted.

If the existing system had vents installed, then this will need to be maintained as they provide ventilation to the roof.

An illustration showing the corner of a garden with a fence and a hedge

Fence, gate or garden wall

You will not need to apply for planning permission if you wish to erect a new; or alter, maintain, improve or take down* an existing fence, wall or gate if specific conditions are met. If any of the conditions are not met, then you will need to apply for planning permission.

Fences, walls and gates do not require building regulation approval.

However, the structures must be structurally sound and maintained.

If the garden wall is classes as a 'party fence wall' then you may have to notify the adjoining owner.

a close up illustration of a chimney

Flue, chimney, and soil or vent pipes

Fitting, altering or replacing a flue, chimney or soil and vent pipe will normally be permitted development, not requiring planning consent, providing certain rules and conditions are met.

Part J of the building regulations seeks to ensure, among other things, that there is adequate provision for the discharge of the products of combustion to the outside air through flues that create enough draught, can take the expected temperatures, are sufficiently gas tight, and discharge at locations away from openings into the building.

Flues and chimneys should be fixed in appropriate places.

Ventilation pipes should finish at least 900mm above any opening into the building within three metres.

An isolated illustration of a fuel tank

Fuel tank

Small domestic fuel tanks can normally be installed without planning permission. However, permission will be required in certain circumstances.

The permitted development regime includes liquid petroleum gas tanks as well as oil storage tanks.

If you live in a listed building, you should check with your local planning authority.

The installation of a fuel tank should meet the necessary building regulations requirements.

If the installation is above ground the requirements will be applied to achieve adequate shielding of the tank from any surrounding fire and containment of any leakage.

An isolated illustration of a large garage

Garage

Planning permission is not usually required for converting a garage, providing the work is internal and does not involve enlarging the building.

However, permission will be required in certain circumstances. If you live in a listed building, you should check with your local planning authority.

If your intention is to convert a garage into a separate house (regardless of who will occupy it), then planning permission may be required no matter what work is involved. We advise that you discuss such proposals with your local planning authority to ensure that any work you do is lawful and correctly permissioned.

Construction of a garage attached to an existing home will normally require building regulations approval.

The construction of an attached carport (open on at least two sides) would not normally require approval if it has a floor area of no more than 30 square metres (except in respect of electrical installations).

The construction of a detached garage would not normally require approval (except in respect of electrical installations), if:

- the floor area is no more than 15 square metres; or

- the floor area is between 15 and 30 square metres and the garage is at least one metre from any boundary or is constructed from substantially non-combustible materials.

Converting any garage into habitable use will normally require building regulations approval.

An isolated illustration of a stone ornamental gatepost

Gatepost ornaments

Bear in mind that ornamental gateposts are subject to the same rules as those that apply to other means of enclosure – fences, walls and gates.

You will need to apply for planning permission if you wish to erect or add to a fence, wall or gate and:

  • It would be over 1 metre high and next to a highway used by vehicles (or the footpath of such a highway)
  • Or over 2 metres high elsewhere or
  • Your right to put up or alter fences, walls and gates is removed by an article 4 direction or a planning condition or
  • Your house is a listed building or in the curtilage of a listed building
  • The fence, wall or gate, or any other boundary involved, forms a boundary with a neighbouring listed building or its curtilage.

Fences, walls and gates do not require building regulation approval.

Although building regulations do not apply, the structures must be structurally sound and maintained.

If the garden wall is classed as a 'party fence wall' and depending on the type of building work you intend to carry out, then you must notify the adjoining owner of the work in respect of the Party Walls Act etc 1996. This does not include wooden fences.

An isolated illustration of a greenhouse

Greenhouses & sheds

Rules governing outbuildings apply to sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse. It does not cover any professional use or use as separate self-contained living accommodation.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject to specific limits and conditions.

If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

An isolated illustration depicting an exposed ground source heat pump

Ground source heat pump

Installing a ground source heat pump system does not usually need planning permission. If you live in a listed building or a conservation area, however, you should contact your council to check on local policy.

Building regulations apply, and installation should be carried out by a suitably qualified installer.

The equipment, installation and testing of the system must all comply with relevant standards detailed in the 'Low or Zero Carbon Energy Sources: Strategic Guide (LZC)' and 'Domestic Heating Compliance Guide'.

Building regulations also apply to other aspects of the work such as electrical installation and plumbing.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1.

Ground source heat pumps transfer heat from the ground into a building to provide space heating and, in some cases, to pre-heat domestic hot water.

A close up illustration of a hedge

High hedges

You don’t normally need planning permission to plant a hedge in your garden. If, however, a planning condition or a covenant restricts planting (for example, on ‘open plan’ estates, or where a driver's sight line could be blocked) you may need planning permission and/or other consent.

There are no laws that say how high you can grow your hedge, but you are responsible for looking after any hedge on your property and for making sure it is not a nuisance to anyone else.

Hedges can occasionally be the source of disputes between neighbours. High, evergreen hedges are a common source of dispute. Provided they have tried and exhausted all other avenues for resolving their dispute, people can take their complaint about a neighbour's evergreen hedge to their local authority.

Building regulations do not apply to trees and hedges but foundations can be affected by tree roots and soil moisture.

Such matters should be considered when planting/removing trees or building new structures as certain tree species can affect foundations over 20 metres away.

An isolated illustration of an ornate exterior light

Lighting (external)

Light itself, and minor domestic light fittings, are not subject to planning controls.

Nevertheless, if you are planning to install external lighting for security or other purposes, you should ensure that the intensity and direction of light does not disturb others.

If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

If you are carrying out electrical work and fixing lighting to the outside of your house in England and Wales, you will have to follow the building regulations rules.

You should use an installer who is registered with a competent person scheme or if an installer is not a registered competent person, they can use a competent person to certify work as an alternative to seeking approval from a building control body.

An isolated illustration of a gutter and downpipe

Maintaining drainpipes

You do not usually need to apply for planning permission for repairs, maintenance, and very minor works.

Permitted development rights may be available for works that go beyond repair, maintenance, and very minor works. However, you should always check with the local planning authority to confirm that rights have not been removed.

Internal or external works to listed buildings are likely to require listed building consent.

If you wish to repair or replace an existing drainpipe, manhole or associated fitting, approval under the building regulations is not normally required if the replacement is like for like.

However, the provision of a new drainpipe, manhole or associated fitting will normally require approval under the building regulations.

They will apply to new rainwater or foul drains inside as well as outside the building. The building regulations also apply to all non-mains foul sewerage arrangements (i.e. those using septic tanks), including their outlets and drainage fields.

Ventilation pipes should finish at least 900mm above any opening into the building within three metres.

An isolated illustration of a manhole cover

Manholes and drains

Although the work itself may not require planning permission you should clarify ownership and responsibility before modifying or carrying out maintenance.

Drains, sewers and manholes may be shared with neighbours or owned by the relevant water authority.

Failure to confirm these details or to comply with relevant standards/legislation could lead to legal and remedial action at your own cost.

Don't forget to consider utilities when planning your project.

If you wish to repair or replace an existing drainpipe, manhole or associated fitting, approval under the building regulations is not normally required if the replacement is like for like.

However, the provision of a new drainpipe, manhole or associated fitting will normally require approval under the building regulations.

An isolated illustration of an isolated outbuilding

Outbuildings

Rules governing outbuildings apply to summerhouses, sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse. It does not cover any professional use or use as separate self-contained living accommodation.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject to specific limits and conditions.

Find out more about the planning rules for outbuildings.

Visit the Outbuilding Mini Guide for detailed information

If you want to put up small, detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

It can be greener to build extra space in the garden than it is to extend the existing house and as with any project, it’s important to consider how to construct your new outbuilding in the most sustainable way possible.

An illustration of a car on a driveway

Patio, driveway and hardstanding

Please note: For guidance on work to your front garden (the area of land between the front walls of the house and the highway) see: paving your front garden.

Elsewhere around your house there are no restrictions on the area of land which you can cover with hard surfaces at, or near, ground level. However, significant works of embanking or terracing to support a hard surface might need a planning application. If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

Generally, a new driveway or patio area does not require building regulations approval.

However, you will need to make sure that any alterations do not make access to the dwelling any less satisfactory than it was before.

Avoid using concrete or tarmac on your patio - this can help to keep gardens cool in summer.  

Slow down water drainage into the ground by using porous materials or open structures such as gravel on driveways and in the garden.

An illustration showing the front path of a house leading to a porch

Paving your front garden

You don’t need planning permission to build or replace a driveway of any size if:

  • you use permeable (or porous) surfacing, e.g. gravel, permeable concrete block paving or porous asphalt
  • the rainwater flows to a lawn or border to drain naturally.

If you cover more than five square metres using traditional materials that don’t let water through, you need planning permission.

These rules apply to the area of land between the front walls of the house and the highway.

Building regulations do not generally apply. However, you will need to make sure that any alterations do not make access to the dwelling any less satisfactory than it was before.

So, for example, changing levels to introduce steps where none existed before would be a contravention of the regulations.

Consider using permeable materials (such as gravel and pebbles) that allow rainwater to pass through them and to drain slowly into the ground rather than quickly running off into drains and increasing the risk of flooding.

An illustration of an isolated enclosed porch with a roof and external lighting

Porch

You will need to apply for planning permission if the porch:

  • Would have a ground area (measured externally) of more than 3 square metres
  • Would be higher than 3 metres above ground level (height needs to be measured in the same way as for a house extension); or
  • Would be less than 2 metres away from the boundary of a dwellinghouse with a highway (which includes all public roads, footpaths, bridleways and byways).
Visit the Porch Mini Guide for detailed information

The construction of a porch built at ground level with a floor area of no more than 30 square metres is normally exempt from building regulations approval, provided that any glazing and fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales).

In addition, for a porch to be exempt from building regulations approval, the front entrance door between the existing house and the new porch must remain in place, and where the house has ramped or level access for disabled people, it is essential that the porch must not adversely affect the access.

An enclosed space around an external door will help with draught proofing and energy saving..

An illustration of a roof from above

Roof

Alterations to the roof of a house (e.g. to re-roof or insert skylights) is considered to be permitted development (not requiring planning permission) subject to certain limits and conditions.

Read about the limits and conditions for work to a roof.

If you live in a flat, listed building or designated area (conservation area, national park, Area of Outstanding Natural Beauty, etc...) you should check with your local planning authority before carrying out any work.

Flats and maisonettes

The planning regime for flats and maisonettes differs in many important ways to that which covers houses.

Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats.

Read guidance specific to flats.

If you want to carry out repairs on or re-cover an existing pitched or flat roof you will not normally need to submit a building control application if:

- Less than 25 per cent of the total ‘building envelope’ (walls, floor, roof, windows, door, roof windows and roof-lights) is affected; and

- Less than 50 per cent of the roof is affected.

 

However, you will need approval if:

- You exceed the limits stated above (in which case there may also be further considerations that could require work to the entire roof, such as ensuring the thermal insulation is sufficient)

- You carry out structural alterations

- The performance of any new covering will be significantly different to that of the existing covering in the event of a fire

- You use a new covering material which increases the weight of the roof covering by 15 per cent or more.

 

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to the relevant Competent Person Schemes.

Read more about building regulations for a roof.

 

Protected species

Although planning permission may not be required, a wildlife licence may be required if the work will affect protected species like bats.

Contact Natural England for advice

 

Flats and maisonettes

Building regulations approval is required to convert a loft or attic into a liveable space.

An illustration of a roof from above with a skylight

Roof window

New roof lights or skylights will not normally require an application for planning permission providing:

  • they do not protrude more than 150mm beyond the plane of the roof slope
  • they are no higher than the highest part of the roof
  • if they are in side elevation roof slope, they must be obscure-glazed and either non opening or more than 1.7 metres above the floor level

However, if additional volume is created it may be treated as an extension and separate rules will apply.

If you live in a listed building or designated area (conservation area, national park, area of outstanding natural beauty, etc...) you should check with your local planning authority before carrying out any work.

Flats and maisonettes

The planning regime for flats and maisonettes differs in many important ways to that which covers houses. Local policy and interpretation of the rules covering changing windows in flats varies from council to council and you are advised to contact your local planning authority for advice before starting work. If you are a leaseholder, you may first need to get permission from your landlord, freeholder or management company.

If you would like to install a roof light or roof window, then building regulations are likely to apply for the following reasons:

  • to install a roof light the roof structure will generally need to be altered to create the opening
  • the roof will have to be able to carry the load (weight) of the new roof light, if the roof cannot do this, then it will need to be strengthened
  • any window that is installed will need to prove that it has sufficient insulation against heat loss (i.e. it is energy efficient).

Where a roof light is replaced, building regulations approval will be required.

Flats and maisonettes

Building regulations apply to all replacement glazing. The regulations apply to thermal performance and other areas such as safety, air supply, means of escape and ventilation.

An isolated illustration of a satellite dish

Satellite dishes, aerials and antennas

Normal domestic TV and radio aerials do not need planning permission, as long as they meet certain requirements.

In certain circumstances, you will need to apply for planning permission to install a satellite dish on your house.

Remember, you are responsible for the appropriate siting of satellite dishes.

Building regulations do not generally apply but you should take care that the installation is safe and the fixing point stable.

An isolated illustration of an alarm

Security alarm

Planning permission is not normally required for installing a security alarm, though if you live in a listed building or conservation area you should check with your local planning authority.

Installing a security alarm system should not be captured by the building regulations. However, the electrical work required will need to comply with the relevant standards.

An isolated illustration of free standing solar panels

Solar panels (ground level)

Installing solar panels domestically should not usually require an application for planning permission so long as the conditions and limits are met.

You should also consider your location and the positioning of panels to maximise the amount of energy generated.

If you live in a listed building ordesignated area (conservation area, national park, area of outstanding naturalbeauty, etc...) you should check with your local planning authority beforecarrying out any work.

Energy efficiency work may also be carried out mostly without the need for building regulations approval.

However, building regulations also apply to other aspects of the work such as electrical installation.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either a Microgeneration Certification Scheme or the relevant Competent Person Scheme.

A zoomed in isolated illustration of a group of solar panels

Solar panels (roof mounted)

In many cases fixing solar panels to your roof is likely to be considered 'permitted development' under planning law with no need to apply for planning permission.

There are, however, important exceptions and provisos which must be observed.

If you are a leaseholder, you may need to get permission from your landlord, freeholder or management company.

If you wish to install a solar panel on your roof building regulations will normally apply.

The ability of the existing roof to carry the load (weight) of the panel will need to be checked and proven. Some strengthening work may be needed.

Building regulations also apply to other aspects of the work such as electrical installation.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

Swimming pool

Outdoor domestic swimming pools can be either in-ground or above ground and may be constructed using various methods, such as a vinyl liner, concrete with tiles, or pre-formed fibreglass shell.

In many cases, planning permission is not required for installing an outdoor pool, as they may fall under permitted development rights, provided they comply with specific limits and conditions. These limits and conditions can be found in the outbuildings guidance on Planning Portal.

Read outbuildings guidance.

Always contact your local planning authority if you are unsure.

Find your local planning authority

Building regulations approval is not normally required for outdoor swimming pools, provided it is not enclosed. However, you should check with your local council's building control team if you are unsure if approval is needed.

An illustration of a single tree in front a of a hedge

Trees and hedges

Many trees are protected by Tree Preservation Orders (TPOs) which mean that, in general, you need the council’s consent to prune or fell them.

In addition, there are controls over many other trees in conservation areas and other designated areas.

You don't normally need permission to plant a hedge in your garden and there are no laws to say how high you can grow your hedge. But you are responsible for looking after any hedge on your property and for making sure it is not a nuisance to anyone else. This means trimming the hedge regularly, both its top and all sides.

If you are in any doubt about the status of the trees or hedgerows you plan to work on should contact your local council before you start.

Building regulations do not apply to trees and hedges but foundations can be affected by tree roots and soil moisture.

An illustration depicting exposed underpinning rods

Underpinning and foundations

Planning permission is not normally required for work to maintain foundations though if you live in a listed building you should check with your local planning authority.

If you need to underpin all or part of the foundations to your building, the building regulations will apply.

The regulations specifically define this as 'building work'.

The appropriate requirements will be applied to ensure that the underpinning will stabilise the movement of the building.

Particular regard will need to be given to the effect on any sewers and drains near the work.

Learn more about building regulations for underpinning.

An isolated illustration of a wind turbine

Wind turbines (wall and roof mounted)

Under permitted development rights which came into force in 2011, in some cases it will be possible to install domestic wind turbines without the need for an application for planning permission, so long as specified limits and conditions are met.

In other cases, you will need to apply for planning permission from your local authority to add a domestic wind turbine to your house or grounds surrounding your home.

You should also consider the average wind speeds in your area and how surrounding structures, trees, topographical features and the turbine's position would affect its ability to generate energy.

The building regulations may apply to wind turbines attached to buildings.

However, the use of wind turbines and other microgeneration systems are encouraged but must demonstrate compliance with the following Parts of the Approved Documents:

- Part L

- Part A (Structural safety)

- Part P (Electrical safety).

Read the Approved Documents L, A and P.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

Small scale wind turbines use the wind's lift forces to turn aerodynamic blades that turn a rotor which creates electricity.

Windows and doors (houses)

You do not usually need to apply for planning permission for:

  • repairs,  maintenance, and minor improvements, such as repainting window and door frames
  • insertion of new windows and doors that are of a similar appearance to those used in the construction of the house (note - a new bay window will be treated as an extension and may require permission)
  • installation of internal secondary glazing.

New roof lights or skylights will not normally require an application for planning permission as long as certain conditions are met.

Occasionally, you may need to apply for planning permission for some of these works because your council has made an Article 4 Direction to withdraw permitted development rights. If you live in a listed building, you will need listed building consent for any significant works - internal or external and you should contact your local planning authority before starting work.

Read more about listed building consent

The permitted development allowances described here apply to houses and not to flats and maisonettes.

If you replace a window(s) in your home, or any other type of building, the building regulations:

- will normally apply if you are replacing the whole of the fixed frame and opening parts or creating new openings for windows or doors

- will not normally apply if the work amounts to no more than, for example, replacing broken glass, rotten sashes or rotten sections of the main frame members.

Replacement of external doors with 50 percent glazing or more will require approval.

For replacement windows and glazed doors, if the contractor carrying out the work is registered with one of the relevant Competent Person Schemes, then you would not need to make an application.

New external windows and doors must meet certain heat loss standards to satisfy building regulations.

Additional storey - extending upwards

Building an additional storey on to your house is considered to be permitted development, subject to certain limits and conditions. An application for the local authority’s prior approval will also be required.

The permitted development allowances described here apply to houses and not to flats and maisonettes.

Building regulations approval is required to add additional storeys to an existing building to make it into a liveable space. The regulations will need to be adhered to in terms of structural strength, stability, stairs, sound insulation, fire safety and ventilation.

An illustration depicting a basement of a house showing gym equipment
Basement

The planning regime covering the creation of living space in basements is evolving and under review.

Converting an existing residential cellar or basement into a living space is in most cases unlikely to require planning permission as long as it is not a separate unit or unless the usage is significantly changed or a light well is added, which alters the external appearance of the property.

Excavating to create a new basement which involves major works, a new separate unit of accommodation and/or alters the external appearance of the house, such as adding a light well, is likely to require planning permission.

If you live in a listed building, you are likely to need consent for internal or external work.

In all circumstances you are advised to contact your local planning authority for guidance on local policy before starting any work.

Building regulations apply. They cover areas such as fire escape routes, ventilation, ceiling height, damp proofing, electrical wiring and water supplies.

Underpinning and foundation work may also be needed.

You must also consider the Party Wall Act 1996 if other properties adjoin yours and you share walls.

The 'Basements for Dwellings' guidance was removed from the list of approved documents on 1October 2010. The Basement Information Centre has developed updated guidance on this topic.

Illustration showing a domestic bathroom showing WC, bath and sink
Bathroom

Planning permission is not normally required for maintenance/replacement of bathrooms though if you live in a listed building you should check with your local planning authority.

If you want to install fittings such as a bath, WC, shower or washbasin within your home, or any other type of building, the building regulations will apply. Building regulations will also apply if the work involves installing an additional fitting or fittings. If you want to install, or replace your bath with, a whirlpool or spa bath, the building regulations may apply.

If you are renovating a bathroom, think about the amount of water you are going to use and how you can make sustainable choices.

Illustration showing a domestic central heating boiler
Boilers and heating

Planning permission is not normally required for installation or replacement of a boiler, although if you live in a listed building you should check with your local planning authority.

If the boiler or heating system require the installation of a flue outside, then you may need planning permission. However, it will normally fall under permitted development.

Building regulations will apply if you want to:

  • Install or replace a hot water cylinder
  • Install, replace or alter the position of any type of gas, solid fuel and oil appliances (including boilers)
  • Install a fixed, flueless, gas appliance

However, if you employ a registered installer with the relevant competencies to carry out the work on gas appliances, they should be able to self-certify the work without the need for close involvement of building control.

Using a high efficiency boiler could save you money and significantly cut your home’s CO2 emissions.

Illustration showing the ceiling of a kitchen in a house
Ceiling

Planning permission is not normally required for maintenance of ceilings, although if you live in a listed building you should check with your local planning authority.

Where more than 25 per cent of a ceiling below a cold loft space or flat roof is being replaced then the building regulations would normally apply, and the thermal insulation of that ceiling would normally have to be improved.

An illustration of a two black framed blue and orange abstract prints
Decoration

Planning permission is not normally required for internal decorations though if you live in a listed building you should check with your local planning authority.

Any internal decorating such as wallpapering, new skirting boards or painting will not require a building control application.

An illustration of a domestic fuse box with the lid open and exposed trip switches
Electrics

Planning permission is not normally required for maintenance/installation of electrics though if you live in a listed building you should check with your local planning authority.

If you are carrying out electrical installation work in your home or garden, you must comply with the rules in the building regulations. It is best to use an installer registered with a competent person scheme who will self-certify compliance with the building regulations.

If an installer is not registered, then certain riskier jobs will need to be inspected and approved by either a building control body or an electrician registered with a third-party certification scheme – who must be notified before work starts.

You do not need to notify them of most repairs, replacements and maintenance work, or minor alterations such as extra power points or lighting points provided these are outside the bathroom.

Illustration showing the floor of a house interior
Floor

Planning permission is not normally required for maintenance of floors though if you live in a listed building you should check with your local planning authority.

If you are replacing or fitting a new floor building regulations would normally apply. Factors to consider include load bearing capacity, thermal and sound insulation, and fire safety.

If you have a suspended timber ground floor you can make significant energy savings by sealing any gaps to stop draughts.

Illustration showing the working elements of a ground source heat pump distributor
Ground source heat pump distributor (internal)

Installing a ground source heat pump system does not usually need planning permission. If you live in a listed building or a conservation area, however, you should contact your council to check on local policy.

Where this is installed as part of works to provide a new or replace an existing heating and hot water system the building regulations energy efficiency requirements apply.

Other technical requirements would apply too if, for instance, the works included in the electrical or drainage work.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1.  

Heat pumps transfer heat into a building to provide space heating and, in some cases, to pre-heat domestic hot water.

Illustration of insulation in the loft of a residential property
Insulation

Planning permission is not normally required for fitting insulation (where there is no change in external appearance).

However, if the building is listed or is in a conservation area you should consult your local planning authority.

Insulation has to comply to the relevant building regulations both when installed during construction or when fitted retrospectively.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to the relevant Competent Person Schemes.

Without loft insulation you could be losing as much as a third of your heating costs through your roof.

Illustration of a dividing internal wall of a house
Internal walls

Planning permission is not normally required for maintenance/creation of internal walls though if you live in a listed building you should check with your local planning authority.

If you wish to remove an internal wall, or form an opening in an internal wall, building regulations will normally apply.

Care should be taken before removing internal walls as these could have a number of functions that could affect the building and the safety of the occupants within a building.

An illustration of a kitchen of a residential property showing cupboards and sink
Kitchen

Planning permission is not normally required for maintenance/replacement of a kitchen though if you live in a listed building you should check with your local planning authority.

If you want to install fittings such as a kitchen sink within your home, or any other type of building, the building regulations will apply.

Building regulations will apply if the work involves installing an additional fitting or fittings.

Pay close attention to energy ratings and features of appliances. Look for A-rated (energy efficient) kitchen appliances. Also look for aerated taps, which reduce water use.

Illustration showing 3 fitting pendant internal light
Lighting (internal)

Light itself, and minor domestic light fittings, are not subject to planning controls.

Nevertheless, if you are planning to install external lighting for security or other purposes, you should ensure that the intensity and direction of light does not disturb others.

If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

If you are carrying out electrical work and installing lighting in your house, then building regulations will apply.

You should use an installer who is registered with a competent person scheme or if an installer is not a registered competent person, they can use a competent person to certify work as an alternative to seeking approval from a building control body.

However, repairs, replacements and maintenance work or extra lighting points or other alterations to existing circuits (except in a kitchen or bathroom, or outdoors) is allowed.

Energy efficient lighting options can reduce your carbon footprint and save you money on your energy bills.

Illustration of a converted loft space of a house, showing staircase
Loft conversion

Converting the loft of a house is considered to be permitted development (not requiring planning permission) subject to specific limits and conditions. Find out about the limits and conditions from Planning Portal - Read more about loft conversions.

Visit the Loft conversion Mini Guide for detailed information
The permitted development allowances described here apply to houses and not to flats and maisonettes.
Read about loft conversions for flats.

Buildings regulations apply if you want to carry out a loft conversion to your home.

The appropriate requirements of the regulations will be applied to ensure, for example: the structural strength of the new floor is sufficient; the stability of the structure (including the existing roof) is not endangered; safe escape from fire; safely designed stairs to the new floor; and reasonable sound insulation between the conversion and the rooms below.

You will also need to consider whether your loft conversion project is subject to The Party Wall etc. Act 1996 under which you must give adjoining owners notice.

Learn more about building regulations for loft conversions on the Planning Portal.

Protected species

Although planning permission is not required, a wildlife licence may be required if the work will affect protected species like bats.

Illustration of a micro combined heat and power unit and its configuration
Micro-combined heat and power (biomass)

Planning permission is not normally needed when installing a micro-combined heat and power or biomass system in a house if the work is all internal.

If the installation requires a flue outside, however, it will normally be permitted development if the relevant conditions are met.

You must adhere to the building regulations set out in Approved Document L: Volume 1.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant  Competent Person Schemes.

Micro-combined heat and power systems for individual homes are a relatively recent development but units resembling gas-fired boilers can now provide not only heat for space and water heating but also electricity to power domestic lights and appliances.

Producing energy from biomass is a carbon-neutral process and has both environmental and economic advantages.

Illustration of a white column domestic radiator
Radiator

Planning permission is not normally required for installation or replacement of radiators though if you live in a listed building you should check with your local planning authority.

If a heating system or hot water system is to be replaced then an application may not be required, and, if it is required, it may not be necessary to apply in advance of carrying out the work.

Careful placement of radiators and use of energy saving designs will make your heating more efficient.

Illustration of a side facing domestic smoke alarm
Smoke alarm

Planning permission is not normally required for installing a smoke alarm, though if you live in a listed building or conservation area you should check with your local planning authority.

If you are building a loft conversion, extension or altering the layout of your home building regulations (Part B Fire Safety) would normally apply.

Building regulations require the installation of automatic smoke detectors to all new dwellings and loft conversions.

Advice should be taken on the type of smoke alarm(s) to be fitted, positioning and installation.

Illustration of a straight staircase with brown balustrade
Stairs and staircases

Planning permission for a new or replacement staircase is not normally required. However, if you live in a listed building you may have to apply for listed building consent.

Part K of the building regulations requires that stairs, ladders and ramps shall be so designed, constructed and installed as to be safe for people moving between different levels in or about the building.

Loft conversions: To ensure adequate fire safety for the dwelling a new stair serving a new room(s) will be needed. Where there is not enough room for a full traditional stair, it may be possible to use a space saving stair. Retractable ladders or stairs are not normally acceptable.

Illustration of a house's loft space partly boarded
Unimproved loft space

Boarding out your loft for storage does not require planning permission. If you intend to convert a loft into a liveable space, please refer to our loft conversions advice.

Protected species

Although planning permission is not required, a wildlife licence may be required if the work will affect protected species like bats.
Contact Natural England for advice.

In most homes, the timber joists that form the ‘floor’ of the loft space will not have been designed to support a significant weight.

If you decide to lay flooring boards over the existing joists in the loft space, this may require a building control application. Your local building control body will be able to advise you on this issue.

Adverts and signs

Planning permission is not normally required for a small sign, for instance with your house name or number on it.

Learn more about adverts and signs.

You may need to apply for advertisement consent to display an advertisement bigger than 0.3 square metres, however, and the planning regime for larger, professional adverts, signs for businesses etc. is complex.

Domestic adverts and signs are not normally subject to building control, although, if a lit sign, any electrical work would be. In all cases signs must 'be kept in a safe condition'.

An illustration of an external heat pump
Air source heat pump

Since December 2011, the installation of an air source heat pump on domestic premises has been considered to be permitted development, not needing an application for planning permission, provided specified limits and conditions are met.

If you live in a listed building or a conservation area you should also contact your council to check any local policy.

Building regulations will normally apply to installing an air source heat pump.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1 (Section 6, Page 45).

Air source heat pumps transfer heat from the air into a building to provide electric heating that generates hot water which can be used for space heating and/or hot water.

An illustration of a free standing barbecue
Barbecue

Many kinds of buildings and structures can be built in your garden or on the land around your house without the need to apply for planning permission.

There are, however, limits and conditions which must be followed, and in some circumstances, you will need to apply for planning permission.

Building regulations will apply if your installation involves carrying out electrical or gas works in your home or garden. You should take care that the installation is safe.

You may wish to use an installer who is registered with a competent person scheme or seek approval from a building control body. If you are unsure about whether you are required to comply, you may wish to contact your local building control body.

An illustration of a white CCTV camera
CCTV

Planning permission is not normally required for installing a CCTV camera, though if you live in a listed building or conservation area you should check with your local planning authority.

Building regulations do not generally apply but you should take care that the installation is safe, and the fixed units are stable.  However, if your installation involves carrying out electrical work in your home or garden, you will have to follow new rules in the building regulations.  You may wish to use an installer who is registered with a competent person scheme or seek approval from a building control body. It is advisable to contact an installer who can provide the necessary advice.

An illustration of a conservatory
Conservatories

A conservatory is treated the same as any other extension under planning regulations, regardless of the materials used.

There are conditions and limits to what is allowed without the need for planning permission, and these apply largely to the dimensions of the proposed addition, its position on the house and its proximity to your boundaries.

The permitted development allowances described here apply to houses and not to flats and maisonettes.

A conservatory built with a floor area of no more than 30 square meters is normally exempt from the building regulations, provided that:

  • The conservatory is separated from the building by external quality doors, windows and walls;
  • Any glazing and fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales). Read the Approved Documents.

Any new structural opening or the increased width of the original opening between the conservatory and the existing house will require approval.

A badly designed conservatory can be a huge energy drain for the house as a whole. Correct insulation is vital for preventing avoidable heat loss and consider an all-weather roof..

An illustration of decking next to grass with paving stones
Decking

Putting up decking, or other raised platforms, in your garden is permitted development, not needing an application for planning permission, providing:

  • The decking is no more than 30cm above the ground
  • Together with other extensions, outbuildings etc, the decking or platforms cover no more than 50 per cent of the garden area.
  • None of the decking or platform is on land forward of a wall forming the principal elevation.

In some areas additional limitations may apply. If you are unsure contact your local planning authority.

 Find your local planning authority

The permitted development allowances described here apply to houses and not to flats and maisonettes.

Building regulations should be assumed to apply to every deck structure requiring planning permission.

If you are unsure about whether you are required to comply, you may wish to contact your local building control body.

An illustration of a dormer window
Dormer window

Whether or not you need planning permission for a dormer window or roof extension depends on several factors outlined in our loft conversion advice.

Building regulations approval is required to convert a loft or attic into a liveable space.

An illustration showing a car on a driveway next to a dropped kerb
Dropped kerb

A crossing across a public footpath or verge for your vehicle to gain access to your property from the highway is known as a dropped kerb, crossover or vehicle crossing.

You will need to make a specific dropped kerb application for a domestic vehicle crossing licence to your local authority through their website.

Don't forget to consider utilities when planning your project.

Building regulations do not generally apply. Work is usually carried out by the local authority.

However, you will need to make sure that any alterations do not make access to the property any less satisfactory than it was before.

A close up illustration of a wall mounted electric vehicle charging unit
Electric vehicle charger

If your home has off-street parking it is likely the installation of a domestic electric vehicle charger will fall under permitted development rights. As such, no planning application is required before the installation begins, provided it meets the criteria.

Planning permission is usually required for:

  • On-street parking
  • Conservation areas  
  • Listed buildings
  • Areas where the installation of electric vehicle (EV) chargers is restricted  
  • More than one upstand per parking space.

Building regulations approval is always required when installing an EV home charger and a competent and reputable installer should be used. There are specific processes related to notifying your local building control authority of a new installation.

Electric cars are better for the environment than petrol and diesel cars as they produce less emissions. To encourage motorists to switch to electric powered cars, there are various incentives available, such as grants for tenants or homeowners to help buy and install a charge point on a property that has on-street parking. .

An illustration of an isolated single story extension
Extensions and additions - detached

You can often extend or add to your house without the need to apply for planning permission provided you meet set limits and conditions.

The regime for what is allowed without planning permission applies largely to the dimensions of the proposed extension, its position on the house and its proximity to your boundaries.

You will also need to apply for planning permission if more than half the area of land around the ‘original house’ would be covered by additions or other buildings. Learn more about extensions.

NOTE: The extension featured here is for illustrative purposes.

A close up illustration of the outside wall of a house
External walls

You do not need to apply for planning permission for repairs, maintenance or minor improvements, such as painting your house.

If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

If you live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads, you will need to apply for planning permission before cladding the outside of your house with stone, tiles, artificial stone, plastic or timber.

The permitted development allowances described here apply to houses and not to flats and maisonettes.

More information

Learn about the planning rules for external walls.

Learn about wall insulation.

Safety advice

If you want to re-render or replace timber cladding to external walls, the building regulations may apply depending on the extent of the work.

Where 25% or more of an external wall is re-rendered, re-clad, re-plastered or re-lined internally or where 25% or more of the external leaf of a wall is rebuilt, the regulations would normally apply, and the thermal insulation would normally have to be improved.

A close up illustration of the outside wall of a flat
External walls (flats)

You will not need to apply for planning permission to paint or maintain the external walls of your flat or maisonette. However, in some areas these rights have been removed (by way of what is known as an Article 4 direction).

If you are a leaseholder, you may first need to get permission from your landlord, freeholder or management company.

If your flat is a listed building, you will need listed building consent, unless it is repainting in the existing colour, and you should contact your local planning authority to determine this.

Works to a listed building that affect its special historic character without consent is a criminal offence.

Safety advice

If you want to re-render or replace timber cladding to external walls, the building regulations may apply depending on the extent of the work.

Where 25 per cent or more of an external wall is re-rendered, re-clad, re-plastered or re-lined internally or where 25 per cent or more of the external leaf of a wall is rebuilt, the regulations would normally apply, and the thermal insulation would normally have to be improved.

Fascia

Maintenance of a fascia such as replacement or painting generally does not require planning permission.

However, if you live in a listed building or designated area (conservation area, national park, area of outstanding natural beauty, etc...) you should check with your local planning authority before carrying out any work.

Safety advice

The replacement of any fascia board or soffit will not normally require a building regulations application to be submitted.

If the existing system had vents installed, then this will need to be maintained as they provide ventilation to the roof.

An illustration showing the corner of a garden with a fence and a hedge
Fence, gate or garden wall

You will not need to apply for planning permission if you wish to erect a new; or alter, maintain, improve or take down* an existing fence, wall or gate if specific conditions are met. If any of the conditions are not met, then you will need to apply for planning permission.

Fences, walls and gates do not require building regulation approval.

However, the structures must be structurally sound and maintained.

If the garden wall is classes as a 'party fence wall' then you may have to notify the adjoining owner.

a close up illustration of a chimney
Flue, chimney, and soil or vent pipes

Fitting, altering or replacing a flue, chimney or soil and vent pipe will normally be permitted development, not requiring planning consent, providing certain rules and conditions are met.

Part J of the building regulations seeks to ensure, among other things, that there is adequate provision for the discharge of the products of combustion to the outside air through flues that create enough draught, can take the expected temperatures, are sufficiently gas tight, and discharge at locations away from openings into the building.

Flues and chimneys should be fixed in appropriate places.

Ventilation pipes should finish at least 900mm above any opening into the building within three metres.

An isolated illustration of a fuel tank
Fuel tank

Small domestic fuel tanks can normally be installed without planning permission. However, permission will be required in certain circumstances.

The permitted development regime includes liquid petroleum gas tanks as well as oil storage tanks.

If you live in a listed building, you should check with your local planning authority.

The installation of a fuel tank should meet the necessary building regulations requirements.

If the installation is above ground the requirements will be applied to achieve adequate shielding of the tank from any surrounding fire and containment of any leakage.

An isolated illustration of a large garage
Garage

Planning permission is not usually required for converting a garage, providing the work is internal and does not involve enlarging the building.

However, permission will be required in certain circumstances. If you live in a listed building, you should check with your local planning authority.

If your intention is to convert a garage into a separate house (regardless of who will occupy it), then planning permission may be required no matter what work is involved. We advise that you discuss such proposals with your local planning authority to ensure that any work you do is lawful and correctly permissioned.

Construction of a garage attached to an existing home will normally require building regulations approval.

The construction of an attached carport (open on at least two sides) would not normally require approval if it has a floor area of no more than 30 square metres (except in respect of electrical installations).

The construction of a detached garage would not normally require approval (except in respect of electrical installations), if:

- the floor area is no more than 15 square metres; or

- the floor area is between 15 and 30 square metres and the garage is at least one metre from any boundary or is constructed from substantially non-combustible materials.

Converting any garage into habitable use will normally require building regulations approval.

An isolated illustration of a stone ornamental gatepost
Gatepost ornaments

Bear in mind that ornamental gateposts are subject to the same rules as those that apply to other means of enclosure – fences, walls and gates.

You will need to apply for planning permission if you wish to erect or add to a fence, wall or gate and:

  • It would be over 1 metre high and next to a highway used by vehicles (or the footpath of such a highway)
  • Or over 2 metres high elsewhere or
  • Your right to put up or alter fences, walls and gates is removed by an article 4 direction or a planning condition or
  • Your house is a listed building or in the curtilage of a listed building
  • The fence, wall or gate, or any other boundary involved, forms a boundary with a neighbouring listed building or its curtilage.

Fences, walls and gates do not require building regulation approval.

Although building regulations do not apply, the structures must be structurally sound and maintained.

If the garden wall is classed as a 'party fence wall' and depending on the type of building work you intend to carry out, then you must notify the adjoining owner of the work in respect of the Party Walls Act etc 1996. This does not include wooden fences.

An isolated illustration of a greenhouse
Greenhouses & sheds

Rules governing outbuildings apply to sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse. It does not cover any professional use or use as separate self-contained living accommodation.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject to specific limits and conditions.

If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

An isolated illustration depicting an exposed ground source heat pump
Ground source heat pump

Installing a ground source heat pump system does not usually need planning permission. If you live in a listed building or a conservation area, however, you should contact your council to check on local policy.

Building regulations apply, and installation should be carried out by a suitably qualified installer.

The equipment, installation and testing of the system must all comply with relevant standards detailed in the 'Low or Zero Carbon Energy Sources: Strategic Guide (LZC)' and 'Domestic Heating Compliance Guide'.

Building regulations also apply to other aspects of the work such as electrical installation and plumbing.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1.

Ground source heat pumps transfer heat from the ground into a building to provide space heating and, in some cases, to pre-heat domestic hot water.

A close up illustration of a hedge
High hedges

You don’t normally need planning permission to plant a hedge in your garden. If, however, a planning condition or a covenant restricts planting (for example, on ‘open plan’ estates, or where a driver's sight line could be blocked) you may need planning permission and/or other consent.

There are no laws that say how high you can grow your hedge, but you are responsible for looking after any hedge on your property and for making sure it is not a nuisance to anyone else.

Hedges can occasionally be the source of disputes between neighbours. High, evergreen hedges are a common source of dispute. Provided they have tried and exhausted all other avenues for resolving their dispute, people can take their complaint about a neighbour's evergreen hedge to their local authority.

Building regulations do not apply to trees and hedges but foundations can be affected by tree roots and soil moisture.

Such matters should be considered when planting/removing trees or building new structures as certain tree species can affect foundations over 20 metres away.

An isolated illustration of an ornate exterior light
Lighting (external)

Light itself, and minor domestic light fittings, are not subject to planning controls.

Nevertheless, if you are planning to install external lighting for security or other purposes, you should ensure that the intensity and direction of light does not disturb others.

If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

If you are carrying out electrical work and fixing lighting to the outside of your house in England and Wales, you will have to follow the building regulations rules.

You should use an installer who is registered with a competent person scheme or if an installer is not a registered competent person, they can use a competent person to certify work as an alternative to seeking approval from a building control body.

Maintaining drainpipes

You do not usually need to apply for planning permission for repairs, maintenance, and very minor works.

Permitted development rights may be available for works that go beyond repair, maintenance, and very minor works. However, you should always check with the local planning authority to confirm that rights have not been removed.

Internal or external works to listed buildings are likely to require listed building consent.

If you wish to repair or replace an existing drainpipe, manhole or associated fitting, approval under the building regulations is not normally required if the replacement is like for like.

However, the provision of a new drainpipe, manhole or associated fitting will normally require approval under the building regulations.

They will apply to new rainwater or foul drains inside as well as outside the building. The building regulations also apply to all non-mains foul sewerage arrangements (i.e. those using septic tanks), including their outlets and drainage fields.

Ventilation pipes should finish at least 900mm above any opening into the building within three metres.

Manholes and drains

Although the work itself may not require planning permission you should clarify ownership and responsibility before modifying or carrying out maintenance.

Drains, sewers and manholes may be shared with neighbours or owned by the relevant water authority.

Failure to confirm these details or to comply with relevant standards/legislation could lead to legal and remedial action at your own cost.

Don't forget to consider utilities when planning your project.

An isolated illustration of an isolated outbuilding
Outbuildings

Rules governing outbuildings apply to summerhouses, sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse. It does not cover any professional use or use as separate self-contained living accommodation.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject to specific limits and conditions.

Find out more about the planning rules for outbuildings.

Visit the Outbuilding Mini Guide for detailed information

If you want to put up small, detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

It can be greener to build extra space in the garden than it is to extend the existing house and as with any project, it’s important to consider how to construct your new outbuilding in the most sustainable way possible.

Party wall

Party walls are dealt with under the building regulations. There are no specific planning requirements for party walls.

However, we would always advise that you discuss your proposals with your neighbours, particularly if a party wall is involved.

Some kinds of work carried out to a property may not be building work that is controlled by the building regulations, but may be work which is covered by the Party Wall etc. Act 1996 - which is a separate piece of legislation with different aims.

There will be some instances where both the Party Wall etc. Act, and the building regulations apply to the work being carried out.

You must find out whether work you intend to carry out falls within The Party Wall etc. Act 1996.

An illustration of a car on a driveway
Patio, driveway and hardstanding

Please note: For guidance on work to your front garden (the area of land between the front walls of the house and the highway) see: paving your front garden.

Elsewhere around your house there are no restrictions on the area of land which you can cover with hard surfaces at, or near, ground level. However, significant works of embanking or terracing to support a hard surface might need a planning application. If you live in a listed building, you will need listed building consent for any significant works whether internal or external.

Generally, a new driveway or patio area does not require building regulations approval.

However, you will need to make sure that any alterations do not make access to the dwelling any less satisfactory than it was before.

Avoid using concrete or tarmac on your patio - this can help to keep gardens cool in summer.  

Slow down water drainage into the ground by using porous materials or open structures such as gravel on driveways and in the garden.

An illustration showing the front path of a house leading to a porch
Paving your front garden

You don’t need planning permission to build or replace a driveway of any size if:

  • you use permeable (or porous) surfacing, e.g. gravel, permeable concrete block paving or porous asphalt
  • the rainwater flows to a lawn or border to drain naturally.

If you cover more than five square metres using traditional materials that don’t let water through, you need planning permission.

These rules apply to the area of land between the front walls of the house and the highway.

Building regulations do not generally apply. However, you will need to make sure that any alterations do not make access to the dwelling any less satisfactory than it was before.

So, for example, changing levels to introduce steps where none existed before would be a contravention of the regulations.

Consider using permeable materials (such as gravel and pebbles) that allow rainwater to pass through them and to drain slowly into the ground rather than quickly running off into drains and increasing the risk of flooding.

Porch

You will need to apply for planning permission if the porch:

  • Would have a ground area (measured externally) of more than 3 square metres
  • Would be higher than 3 metres above ground level (height needs to be measured in the same way as for a house extension); or
  • Would be less than 2 metres away from the boundary of a dwellinghouse with a highway (which includes all public roads, footpaths, bridleways and byways).
Visit the Porch Mini Guide for detailed information

The construction of a porch built at ground level with a floor area of no more than 30 square metres is normally exempt from building regulations approval, provided that any glazing and fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales).

In addition, for a porch to be exempt from building regulations approval, the front entrance door between the existing house and the new porch must remain in place, and where the house has ramped or level access for disabled people, it is essential that the porch must not adversely affect the access.

An enclosed space around an external door will help with draught proofing and energy saving..

An illustration of a roof from above
Roof

Alterations to the roof of a house (e.g. to re-roof or insert skylights) is considered to be permitted development (not requiring planning permission) subject to certain limits and conditions.

Read about the limits and conditions for work to a roof.

If you live in a flat, listed building or designated area (conservation area, national park, Area of Outstanding Natural Beauty, etc...) you should check with your local planning authority before carrying out any work.

Flats and maisonettes

The planning regime for flats and maisonettes differs in many important ways to that which covers houses.

Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats.

Read guidance specific to flats.

If you want to carry out repairs on or re-cover an existing pitched or flat roof you will not normally need to submit a building control application if:

- Less than 25 per cent of the total ‘building envelope’ (walls, floor, roof, windows, door, roof windows and roof-lights) is affected; and

- Less than 50 per cent of the roof is affected.

 

However, you will need approval if:

- You exceed the limits stated above (in which case there may also be further considerations that could require work to the entire roof, such as ensuring the thermal insulation is sufficient)

- You carry out structural alterations

- The performance of any new covering will be significantly different to that of the existing covering in the event of a fire

- You use a new covering material which increases the weight of the roof covering by 15 per cent or more.

 

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to the relevant Competent Person Schemes.

Read more about building regulations for a roof.

 

Protected species

Although planning permission may not be required, a wildlife licence may be required if the work will affect protected species like bats.

Contact Natural England for advice

 

Flats and maisonettes

Building regulations approval is required to convert a loft or attic into a liveable space.

An illustration of a roof from above with a skylight
Roof window

New roof lights or skylights will not normally require an application for planning permission providing:

  • they do not protrude more than 150mm beyond the plane of the roof slope
  • they are no higher than the highest part of the roof
  • if they are in side elevation roof slope, they must be obscure-glazed and either non opening or more than 1.7 metres above the floor level

However, if additional volume is created it may be treated as an extension and separate rules will apply.

If you live in a listed building or designated area (conservation area, national park, area of outstanding natural beauty, etc...) you should check with your local planning authority before carrying out any work.

Flats and maisonettes

The planning regime for flats and maisonettes differs in many important ways to that which covers houses. Local policy and interpretation of the rules covering changing windows in flats varies from council to council and you are advised to contact your local planning authority for advice before starting work. If you are a leaseholder, you may first need to get permission from your landlord, freeholder or management company.

If you would like to install a roof light or roof window, then building regulations are likely to apply for the following reasons:

  • to install a roof light the roof structure will generally need to be altered to create the opening
  • the roof will have to be able to carry the load (weight) of the new roof light, if the roof cannot do this, then it will need to be strengthened
  • any window that is installed will need to prove that it has sufficient insulation against heat loss (i.e. it is energy efficient).

Where a roof light is replaced, building regulations approval will be required.

Flats and maisonettes

Building regulations apply to all replacement glazing. The regulations apply to thermal performance and other areas such as safety, air supply, means of escape and ventilation.

An isolated illustration of a satellite dish
Satellite dishes, aerials and antennas

Normal domestic TV and radio aerials do not need planning permission, as long as they meet certain requirements.

In certain circumstances, you will need to apply for planning permission to install a satellite dish on your house.

Remember, you are responsible for the appropriate siting of satellite dishes.

Building regulations do not generally apply but you should take care that the installation is safe and the fixing point stable.

An isolated illustration of an alarm
Security alarm

Planning permission is not normally required for installing a security alarm, though if you live in a listed building or conservation area you should check with your local planning authority.

Installing a security alarm system should not be captured by the building regulations. However, the electrical work required will need to comply with the relevant standards.

An isolated illustration of free standing solar panels
Solar panels (ground level)

Installing solar panels domestically should not usually require an application for planning permission so long as the conditions and limits are met.

You should also consider your location and the positioning of panels to maximise the amount of energy generated.

If you live in a listed building ordesignated area (conservation area, national park, area of outstanding naturalbeauty, etc...) you should check with your local planning authority beforecarrying out any work.

Energy efficiency work may also be carried out mostly without the need for building regulations approval.

However, building regulations also apply to other aspects of the work such as electrical installation.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either a Microgeneration Certification Scheme or the relevant Competent Person Scheme.

A zoomed in isolated illustration of a group of solar panels
Solar panels (roof mounted)

In many cases fixing solar panels to your roof is likely to be considered 'permitted development' under planning law with no need to apply for planning permission.

There are, however, important exceptions and provisos which must be observed.

If you are a leaseholder, you may need to get permission from your landlord, freeholder or management company.

If you wish to install a solar panel on your roof building regulations will normally apply.

The ability of the existing roof to carry the load (weight) of the panel will need to be checked and proven. Some strengthening work may be needed.

Building regulations also apply to other aspects of the work such as electrical installation.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

Swimming pool

Outdoor domestic swimming pools can be either in-ground or above ground and may be constructed using various methods, such as a vinyl liner, concrete with tiles, or pre-formed fibreglass shell.

In many cases, planning permission is not required for installing an outdoor pool, as they may fall under permitted development rights, provided they comply with specific limits and conditions. These limits and conditions can be found in the outbuildings guidance on Planning Portal.

Read outbuildings guidance.

Always contact your local planning authority if you are unsure.

Find your local planning authority

Building regulations approval is not normally required for outdoor swimming pools, provided it is not enclosed. However, you should check with your local council's building control team if you are unsure if approval is needed.

An illustration of a single tree in front a of a hedge
Trees and hedges

Many trees are protected by Tree Preservation Orders (TPOs) which mean that, in general, you need the council’s consent to prune or fell them.

In addition, there are controls over many other trees in conservation areas and other designated areas.

You don't normally need permission to plant a hedge in your garden and there are no laws to say how high you can grow your hedge. But you are responsible for looking after any hedge on your property and for making sure it is not a nuisance to anyone else. This means trimming the hedge regularly, both its top and all sides.

If you are in any doubt about the status of the trees or hedgerows you plan to work on should contact your local council before you start.

Building regulations do not apply to trees and hedges but foundations can be affected by tree roots and soil moisture.

An illustration depicting exposed underpinning rods
Underpinning and foundations

Planning permission is not normally required for work to maintain foundations though if you live in a listed building you should check with your local planning authority.

If you need to underpin all or part of the foundations to your building, the building regulations will apply.

The regulations specifically define this as 'building work'.

The appropriate requirements will be applied to ensure that the underpinning will stabilise the movement of the building.

Particular regard will need to be given to the effect on any sewers and drains near the work.

Learn more about building regulations for underpinning.

An isolated illustration of a wind turbine
Wind turbines (wall and roof mounted)

Under permitted development rights which came into force in 2011, in some cases it will be possible to install domestic wind turbines without the need for an application for planning permission, so long as specified limits and conditions are met.

In other cases, you will need to apply for planning permission from your local authority to add a domestic wind turbine to your house or grounds surrounding your home.

You should also consider the average wind speeds in your area and how surrounding structures, trees, topographical features and the turbine's position would affect its ability to generate energy.

The building regulations may apply to wind turbines attached to buildings.

However, the use of wind turbines and other microgeneration systems are encouraged but must demonstrate compliance with the following Parts of the Approved Documents:

- Part L

- Part A (Structural safety)

- Part P (Electrical safety).

Read the Approved Documents L, A and P.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.

Small scale wind turbines use the wind's lift forces to turn aerodynamic blades that turn a rotor which creates electricity.

The planning regime for flats and maisonettes differs in many important ways to that which covers houses. Local policy and interpretation of the rules covering changing windows in flats varies from council to council and you are advised to contact your local planning authority for advice before starting work. If you are a leaseholder, you may first need to get permission from your landlord, freeholder or management company.

A close up of 2 bay windows at the front of a house
Windows and doors (houses)

You do not usually need to apply for planning permission for:

  • repairs,  maintenance, and minor improvements, such as repainting window and door frames
  • insertion of new windows and doors that are of a similar appearance to those used in the construction of the house (note - a new bay window will be treated as an extension and may require permission)
  • installation of internal secondary glazing.

New roof lights or skylights will not normally require an application for planning permission as long as certain conditions are met.

Occasionally, you may need to apply for planning permission for some of these works because your council has made an Article 4 Direction to withdraw permitted development rights. If you live in a listed building, you will need listed building consent for any significant works - internal or external and you should contact your local planning authority before starting work.

Read more about listed building consent

The permitted development allowances described here apply to houses and not to flats and maisonettes.

If you replace a window(s) in your home, or any other type of building, the building regulations:

- will normally apply if you are replacing the whole of the fixed frame and opening parts or creating new openings for windows or doors

- will not normally apply if the work amounts to no more than, for example, replacing broken glass, rotten sashes or rotten sections of the main frame members.

Replacement of external doors with 50 percent glazing or more will require approval.

For replacement windows and glazed doors, if the contractor carrying out the work is registered with one of the relevant Competent Person Schemes, then you would not need to make an application.

New external windows and doors must meet certain heat loss standards to satisfy building regulations.

Flats

Flat

External walls (flats)

You will not need to apply for planning permission to paint or maintain the external walls of your flat or maisonette. However, in some areas these rights have been removed (by way of what is known as an Article 4 direction).

If you are a leaseholder, you may first need to get permission from your landlord, freeholder or management company.

If your flat is a listed building, you will need listed building consent, unless it is repainting in the existing colour, and you should contact your local planning authority to determine this.

Works to a listed building that affect its special historic character without consent is a criminal offence.

Safety advice

If you want to re-render or replace timber cladding to external walls, the building regulations may apply depending on the extent of the work.

Where 25 per cent or more of an external wall is re-rendered, re-clad, re-plastered or re-lined internally or where 25 per cent or more of the external leaf of a wall is rebuilt, the regulations would normally apply, and the thermal insulation would normally have to be improved.

Terrace

Terraced house

An illustration of an isolated single story extension
Extensions and additions - semi or terraced

You can often extend or add to your house without the need to apply for planning permission provided you meet a set of limits and conditions.

The regime for what is allowed without planning permission applies largely to the dimensions of the proposed extension, its position on the house and its proximity to your boundaries.

You will also need to apply for planning permission if more than half the area of land around the "original house" would be covered by additions or other buildings.

NOTE: The extension featured here is for illustrative purposes.  

The term 'attached house' means any house that shares a party wall with a neighbouring building.

Building regulations generally apply if you want to build an extension to your home.

However, a porch or conservatory built at ground level and with a floor area of no more than 30 square meters in floor area is normally exempt, provided that any glazing and any fixed electrical installation complies with the applicable requirements of the building regulations (i.e. Part K - ‘Protection from falling, collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales).
