Good news first: for the large majority of homes, installing solar panels does not require planning permission. Most installations fall under what’s known as permitted development. That said, there are some exceptions worth knowing about before you proceed. Here’s a clear guide.
Most solar is permitted development
Roof-mounted solar panels on a typical house are usually allowed without a planning application, provided they meet a few common-sense conditions — for example, that they don’t project too far from the roof slope and don’t sit above the highest part of the roof. For most homeowners, this means you can go ahead without council approval.
When you might need permission
- Listed buildings — you’ll typically need listed building consent, and possibly planning permission.
- Conservation areas — restrictions can apply, particularly for panels on a wall or roof slope facing a road.
- Ground-mounted systems — larger ground arrays can exceed permitted development limits.
- Flats and maisonettes — the rules differ from houses.
Rules can also vary by local authority, so it’s always worth checking your specific situation. As part of your survey, we’ll flag anything that needs attention and can guide you through any applications required.
Building regulations still apply
Even where planning permission isn’t needed, your installation must comply with building regulations — covering electrical safety and the structural load on your roof. Using an MCS-certified installer ensures this is handled correctly and that your system qualifies for export payments.
Frequently asked questions
Do I need permission for solar in a conservation area?
Sometimes. Restrictions often apply to panels visible from the road, so it’s best to check with your local authority. We can advise on the most sympathetic approach for your property.
Do listed buildings allow solar panels?
Often yes, but you’ll usually need listed building consent and careful, discreet placement. It’s very much a case-by-case decision.
