Do I need planning permission for solar panels?

Most homes don't, but there are exceptions. This guide explains what to check.

In short

Most roof-mounted solar panels on houses in England are 'permitted development' and don't need planning permission, provided they don't project more than 200mm from the roof slope or sit above the highest part of the roof. Listed buildings, some conservation areas and some flat-roof or ground-mounted installations need extra checks.

When you usually don't need permission

Panels on the roof of a house (not a flat) in England.
They don't stick out more than 200mm from the roof surface.
They don't go above the highest part of the roof (excluding the chimney).
They're sited to minimise their effect on the look of the building, as far as practical.

When you need to check

Listed buildings, where listed building consent is normally required.
Conservation areas and World Heritage Sites, where extra restrictions can apply, especially on walls facing a road.
Flats and apartment buildings.
Ground-mounted arrays and some flat-roof installations.
Commercial buildings, which have their own permitted development limits.
