Do I need Planning Permission to install Solar Panels?

In many cases, planning permission is not required if solar panels are fixed to the roof of a single dwelling house.

The following apply to roof and wall mounted solar panels:

  • Panels should not be installed above the ridge line and should project no more than 200mm from the roof or wall surface.
  • If your property is a Listed Building, installation is likely to require an application for listed building consent, even where planning permission is not needed.
  • If your property is in a Conservation Area or in a World Heritage Site, planning consent is required when panels are to be fitted on the principal or side elevation walls and they are visible form the highway. If panels are to be fitted to a building in your garden or grounds, they should not be visible from the highway.
  • All solar installations are also subject to the following:
  • Panels on a building should be sited to minimise the effect on the appearance of the building.
  • Should be sited in order to minimise the effect on the amenity of the area.
  • Where they are no longer required for microgeneration, they should be removed as soon as possible

Building Regulations?

With the installation of roof mounted solar panels becoming increasingly popular, it is important to recognise that Building Regulations will Normally Apply should you wish to fit them to your roof.
The issue here is whether the existing roof will be able to take the extra roof loadings that solar panels will impose on it. Therefore, it will be necessary for you to demonstrate that your roof is capable of taking the additional imposed weight.
Building Regulations do not stop there however. Regulations will also apply to the electrical installation and therefore, we recommend you contact a competent person to undertake this work.
