Planning permission for solar in Hertsmere: the checks to separate

Bushey, Bushey Heath, Radlett, Aldenham and Borehamwood are in Hertsmere. Start with the council’s planning service and the full address. Search the relevant record and check any designation before relying on general rooftop-solar advice.

Nearby coverage areas do not share one authority. Watford has its own borough council, Carpenders Park and South Oxhey use Three Rivers, and Stanmore uses Harrow. A postal town or installer service boundary is not a planning boundary.

Some domestic rooftop solar work can proceed under permitted-development rights, subject to the applicable conditions. Equipment position, the type of building and any additional controls can change the route. Check the proposal rather than assuming all panels are treated alike.

Listed buildings, conservation settings and Article 4 directions need particular attention. Use the official Planning Portal and council advice for the current position. A neighbour’s installation is not evidence that your own design needs no consent.

A leaseholder may need freeholder or managing-agent agreement even when planning permission is unnecessary. Agree access, insurance and responsibility for later roof repairs. A planning decision does not amend the lease or grant rights over shared space.

For a garage or outbuilding, identify ownership of the roof and the route used by cables. Keep agreements in writing before detailed installation arrangements are made.

Roof loading, fixings, electrical safety and building-control requirements remain relevant. Ask who arranges each assessment or notification and which handover documents will be supplied.

The electricity network process is different from planning. Your installer should identify the applicable connection route, often described as G98 or G99, and any requirement for prior approval or export limiting. Keep those responsibilities and any outstanding conditions in the written proposal.
