Solar Panels and Planning Permission: What You Need to Know

The Good News: Most Installations Don't Need Permission

Under Permitted Development Rights, roof-mounted solar panels on domestic properties in England are generally exempt from planning permission, provided certain conditions are met. This means most homeowners can proceed without any application.

Permitted Development Conditions for Solar Panels

Your installation qualifies as permitted development if:

• Panels do not protrude more than 200mm from the roof or wall surface
• Panels are not installed on a building that is a listed building or within the curtilage of a listed building
• Panels are not on a wall or roof slope that faces a highway (for buildings in conservation areas)
• The installation does not protrude above the highest point of the roof
• The installation is sited to minimise its effect on the appearance of the building

When You DO Need Planning Permission

Listed Buildings

Any solar installation on a listed building requires Listed Building Consent in addition to planning permission. This applies to all grades (I, II*, and II) in England. Applications must demonstrate that the installation preserves the character and architectural interest of the building.

We regularly work with heritage properties and can help prepare supporting documentation for planning applications. In-roof (integrated) solar systems that sit flush with the existing roof profile are often more readily approved than standard on-roof systems.

Conservation Areas

In conservation areas, solar panels on the principal elevation (the front of the building, if facing a highway) require planning permission. Rear and side installations are usually still permitted development.

The Midlands has many conservation areas — including large portions of Birmingham's Victorian suburbs, Stratford-upon-Avon town centre, and various village conservation areas across Warwickshire and Worcestershire.

Ground Mounted Systems

Ground-mounted solar panels almost always require planning permission, as they constitute a new structure in your garden. The exception is systems under certain size thresholds in rural or domestic settings, but the rules are complex — always check with your local authority before proceeding.

Flat Roofs on Non-Domestic Buildings

Commercial and industrial buildings have different rules. Planning permission is more commonly required for commercial solar installations, especially where systems are visible from public roads.

How to Check Your Local Rules

Planning rules vary by local authority. The best approach is to contact your local council's planning department or use the Planning Portal (planningportal.co.uk) to check your specific situation. Our surveyors are familiar with the planning requirements across all the local authorities we cover in the Midlands.

Scotland, Wales, and Northern Ireland

The rules described above apply to England. Scotland, Wales, and Northern Ireland have their own planning frameworks with different permitted development thresholds. Midland Solar operates in England only.
