What is the difference between a roof window and a dormer window?

A roof window (or skylight) is fitted flush within the slope of a roof, while a dormer projects outward, creating additional headroom and floor space.  

Both can be installed under permitted development but must meet specific size and position limits to qualify.

Common Questions

Can I put a flagpole in my garden and how tall can it be?

You can put one flagpole up to 4.6 metres high in your garden without needing to apply for planning permission. If it is higher than this or you live in a protected area such as a Conservation Area or listed building then consent will be required.

Certain flags can be flown without needing consent, such as national flags.

Read government guidance on flying flags for more information.

Do I need planning or building control for covered outdoor kitchen?

If an outdoor kitchen is not a permanent structure, then planning permission will normally not be required.

Where planning permission is required, it may be granted through permitted development rights, provided it meets the limits set out in legislation. Most outdoor kitchens fall within the set limits unless they are particularly tall or close to a boundary.

While there is no specific permitted development right for ‘outdoor kitchens’ it may be classified as an ‘outbuilding’.

You can view the limitations for outbuildings and outdoor kitchens in the relevant common project

If the structure exceeds the limits set out through permitted development rights, then it will require an application for planning permission.

Different rules may apply if you live in a listed building or conservation area. If this is the case, you may wish to consult your local planning authority.

Read about the building regulations that cover outdoor kitchens.

How long does it take for a decision after I submit my planning application?

Once submitted, your planning application first goes through a validation process. After its validated, the formal decision period is 8 weeks. However, in some cases, especially for more complex proposals or if further information is needed, your local authority may request an extension of time.

What are use classes and change of use?

Categorising land and buildings according to their type and purpose is known as Use Classes.  

A 'Change of use' can be within the same Use Class or from one Use Class to another.

You will need planning permission for certain changes to the use of a property such as changing from a residential use to a business use. However, it is possible to change use between some classes without having to make an application for planning permission.

Depending on the specifics of any proposed change of use, including any building work associated with the proposal, an application for planning permission or prior approval may be required.

My house is in a conservation area, and I want to have solar panels on the garage and roof, do I need permission?

Installing solar panels on your roof will often fall under permitted development rights, meaning an application for planning permission is not required provided certain limits and conditions are met.

The limits and conditions vary based on the type of roof you want to install the solar panels on and the location of the house. See the details below:

·     On a pitched roof, panels should not be installed above the highest part of the roof (excluding the chimney) and should project no more than 200mm from the roof slope or wall surface.

·     On a flat roof the highest part of the solar PV equipment cannot be more than 600mm higher than the highest part of the roof(excluding chimney).

·     The panels must not be installed on a building that is within the grounds of a listed building or on a site designated as a scheduled monument.

·     If your property is in a conservation area, or in a World Heritage Site, panels must not be fitted to a wall which fronts a highway.

As you have stated you’re in a conservation area, you must apply to the local authority for prior approval. This process includes submitting a form to the local planning authority which ensures that you meet the limits set out in legislation.

Forms relating to prior approval for mounting solar equipment can be submitted through the Planning Portal’s online application service and attract a fee of £240.
