For most UK homes, rooftop solar is allowed under 'permitted development' and does not need a full planning application. But there are real exceptions, and getting this right before you install matters, so here is the honest position.
The general rule: permitted development
In England, domestic rooftop solar usually falls under permitted development, provided it meets conditions such as not projecting too far above the roof slope and not being the highest part of the roof. Most standard installs comply, which is why so many go ahead without a planning application.
The main exceptions to watch
- Listed buildings: almost always need listed-building consent.
- Conservation areas: extra restrictions can apply, especially to roof slopes facing a road.
- Flats and maisonettes: different rules may apply.
- Ground-mounted arrays: have their own size and siting limits.
Scotland, Wales and Northern Ireland
Planning is devolved, so permitted-development rules differ across Scotland, Wales and Northern Ireland. The principles are similar but the detail varies, which is why a local installer who knows your nation's rules is worth having.
Why a good installer checks first
A reputable MCS-certified installer confirms permitted-development status, and flags if consent is needed, before quoting and fitting. That protects you from doing work that has to be undone. If anyone skips this step, treat it as a red flag.

Frequently asked questions
Do panels in a conservation area always need permission?
Not always, but the rules are tighter, and front-facing roof slopes are the usual sticking point. A local installer or your council's planning team can confirm for your property.
What about a listed building?
Listed buildings almost always require listed-building consent for solar, and approval is not guaranteed. Specialist advice is essential here.
Does battery storage need planning permission?
A home battery is usually permitted development, but siting and size can matter, particularly for outdoor units. Your installer will advise.
