Most solar panel installations go up without planning permission and without any issue. The ones that attract enforcement notices are almost always in conservation areas or on listed buildings — and the owner didn't check first.
Almost always no — with two important exceptions: conservation areas and listed buildings. Solar panels on a dwelling house are permitted development under Class A of Part 14 of the GPDO.
Panels mounted on the roof or wall of your house are permitted development if they do not protrude more than 200mm from the roof surface, are not higher than the highest point of the roof excluding the chimney, the installation is reversible, and the property is not listed or in a conservation area.
Listed buildings always require listed building consent for solar panels. In a conservation area, panels visible from a highway are not permitted development. Panels projecting more than 200mm from the roof surface require permission. Ground-mounted standalone solar systems are assessed under separate provisions and require their own permitted development assessment.
In a conservation area, solar panels visible from a highway are not permitted development. Many conservation area homeowners install panels on rear roof slopes believing they are not visible — but any view of the panels from any highway including a footpath removes the permitted development right.
A listed building requires listed building consent for any works affecting its character — including solar panels even where they would be permitted development on a non-listed equivalent. Permitted development rights for solar panels on a dwelling house also do not extend to the communal roof of a block of flats.
