The short answer
Most homeowners in England can fit solar panels on their roof without planning permission, under what are called permitted development rights. New rules from 27 August 2026 allow larger installations in more places for houses, and set separate rules for blocks of flats.
When you may need permission
- Listed buildings usually need listed building consent.
- Conservation areas and World Heritage Sites may have extra limits, especially on walls or roofs facing a road.
- Flats and apartments: different rules apply, and you'll also need the freeholder's agreement.
- Article 4 areas: some councils remove permitted development rights in certain streets.
Plug-in solar
The new rules also cover plug-in solar, but don't allow it on wooden structures or cladding.
Scotland, Wales and Northern Ireland
Each has its own planning rules. Rooftop solar on a house is usually allowed without permission there too, with similar exceptions. Check with your local council.
Before you start
- If you're unsure, ask your council for a lawful development certificate. It's useful when you sell the house.
- Your installer should check the rules for your home as part of the quote.
- Building regulations still apply. MCS-certified installers handle this for you.
