What about conservation areas?

You can install solar in conservation areas BUT panels must not face a highway. Rear and side roof installations are usually fine under permitted development. Check with your local planning authority.

Do I need building regulations approval?

Your MCS-certified installer self-certifies compliance with building regulations (Part P electrical, Part L energy). You don't need a separate building control application.

What is a DNO notification?

Your installer notifies your Distribution Network Operator (DNO) about your solar installation. This is a legal requirement (G99) for systems connected to the grid. Your installer handles this — not you.

Can I install on a listed building?

Yes, but you MUST get listed building consent first. Apply to your local planning authority. Many listed buildings are approved — especially for rear/hidden installations.

Do I need planning permission for solar panels?

Most UK residential solar installations need NO planning permission under permitted development rights. The rules: (1) Panels must not protrude more than 200mm from the roof surface. (2) Must not extend above the highest part of the roof (excluding chimneys). (3) Must not face a highway if within a conservation area. (4) Panels must be removed when no longer needed. Exceptions that DO require planning: listed buildings (always), conservation areas (front-facing only), flats/maisonettes, ground-mounted systems over 9m², Article 4 direction areas. Your installer handles the DNO notification (G99) which is separate from planning. Approval rate for solar planning applications: 95%+.
