Do You Need Planning Permission for Solar Panels?
In most cases, no. Roof-mounted solar panels on homes in England are usually classed as permitted development, so no planning application is needed — provided they meet conditions on size and position. Listed buildings and conservation areas are exceptions, and building regulations always apply.This guide explains solar panel planning permission in the UK — permitted development, listed buildings and conservation areas — for NW homes.
It’s one of the most common worries, but for most homes it’s rarely a barrier. Here’s how the rules generally work.
Planning is one part of the wider journey we set out in our solar panel installation process guide.
Do You Need Planning Permission for Solar Panels?
For the majority of homes in England, the answer is no. Most roof-mounted solar installations are classed as permitted development.
That said, rules vary by property and area, so it’s always sensible to confirm your specific situation with your local planning authority before going ahead.

What Are Permitted Development Rights?
Permitted development lets you carry out certain work without a full planning application. For rooftop solar in England, the main conditions are:
-
- Not too proud of the roof: panels shouldn’t protrude more than 200mm beyond the roof slope on a pitched roof.
- Not above the ridge: they shouldn’t sit higher than the highest part of the roof (excluding the chimney).
- Sensible siting: panels should be positioned to minimise visual impact where possible.
Flat Roofs and Ground-Mounted Solar
Flat-roof rules were relaxed at the end of 2023. Panels can now sit up to 600mm above a flat roof surface under permitted development, which makes far more flat-roof installs straightforward.
Ground-mounted solar has its own permitted development limits, including a cap on the area covered. Larger ground arrays may need planning permission, so these are worth checking case by case.
Listed Buildings and Conservation Areas
This is where permission is more likely to be needed.
-
- Listed buildings: generally need listed building consent, and often planning permission too. These are judged case by case.
- Conservation areas: extra restrictions can apply, particularly to roof slopes that front a highway.
- National Parks & AONBs: designated land can carry additional conditions.
Worth knowing: if your home is listed or in a conservation area, always check with your local planning authority before installing. Rules differ in Scotland, Wales and Northern Ireland, which have their own planning frameworks.
Building Regulations Still Apply
Whether or not you need planning permission, solar installations must meet building regulations — covering the electrical work and the roof structure.
A professional installer handles this and provides the right certification, so compliance is taken care of as part of the job.
What If You Do Need Permission?
If your property falls outside permitted development, applying for planning permission is usually a straightforward process through your local council.
If you’d like certainty, you can also apply for a Certificate of Lawful Development to confirm your installation is permitted. We can advise on what’s likely needed for your property as part of a free survey.
