Do you need planning permission to install solar panels in the UK?

One of the most common questions for those considering solar energy is whether planning permission is needed to install solar panels in the UK.


For most homeowners, the good news is that solar panels are usually classed as ‘permitted development’, meaning you won’t need formal planning permission provided certain conditions are met.
These include installing panels so they do not protrude more than 200mm from the roof surface and ensuring the panels are not higher than the highest part of the roof (excluding chimneys).

However, if your property is in a conservation area, a World Heritage Site, or is a listed building, stricter rules apply.
For conservation areas, panels must not be installed on a wall or roof that fronts a highway, and you may need to seek additional approval.
Listed buildings require listed building consent for any alteration, and permission is much harder to obtain, as changes must not affect the building’s character.

Legislation around solar installations is evolving. The UK government is actively encouraging renewable energy and has announced plans to further relax planning laws for solar panels over the coming years, making it easier for households to go green.


If in doubt it is always worth checking with your local planning authority for the latest requirements.
