What documents to I need to make a planning application?

Your planning application must be made up of:

  • The necessary plans of the site
  • The required supporting documentation
  • The completed form
  • The correct fee.

The local planning authority will not be able to process your application unless the mandatory supporting documentation has been provided. You can also attach any other relevant documentation which you think will help the local authority determine the application.

What supporting documentation must be provided depends on the application type,  development type and local planning authority.

There are two levels of mandatory documents, national and local. If you’re applying online, the service will tell you what mandatory documentation you need to provide and allows you to attach the relevant documents. Most applications will require you to provide a location plan and a site plan.

In addition to the national list, your LPA may produce a list which details any specific documentation that is required to accompany the application. The requirements may vary according to the type of application, i.e. household, full, outline, etc. If you are applying online, this list is available from the supporting documents screen or your local planning authority’s website.

Common Questions

What permissions are required for a pond in my garden?

Most garden ponds will fall under permitted development rights, meaning an application for planning permission is not required. In planning terms a pond will be classed as an outbuilding, to read the full rules around installing an outbuilding, visit our common projects section.

For ponds which are particularly deep or large, you may need to apply for planning permission. If you are unsure, you should contact your local planning authority for advice.

In a listed building you will require listed building consent for any major changes.

When installing a pond, you should take into account other regulatory considerations such as environmental permits or any protected species which may be impacted. Further thought will have to be placed when creating ponds near riverways or in areas of flood risk.

What are the planning and building rules for constructing a soakaway?

A soakaway does not normally require an application for planning permission provided it deals with surface water and does not discharge into a public sewer. Additional regulations may apply if you are in a conservation area or within the boundary of a listed building.

Building regulations will apply to the creation of a soakaway. The soakaway must comply with Part H of the building regulations which specifies where they can be located and the size that is permitted.

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.

Is planning permission and building control approval required for removing internal walls in a flat?

Planning permission is not required for moving internal walls in a flat.If the building is a listed building, you may require listed building consent.

Removing a load bearing wall will require building control approval as it is altering the structure of the property. You will be required to provide a report from a structural engineer who will provide structural calculations.

Work on internal walls may also affect fire escape routes, ventilation, drainage or electrics. These should be considered during the design process and work should be carried out by a member of the competent person scheme where possible.

What are the height restrictions for fences, gates and garden walls?

You can usually put up new fences, gates or garden walls without planning permission, as long as you stay within permitted height limits. If the structure is adjacent to a highway (including footpaths), it must not exceed one metre in height. For all other boundaries, the maximum permitted height is two metres. Anything taller than these limits will require planning permission.
