Solar panels, heat pumps and insulation in Boscombe Spa conservation area
In the Boscombe Spa conservation area (Bournemouth, Christchurch and Poole), external wall insulation needs planning permission, and so does an air source heat pump on a wall or roof facing the road; one at the back or side, internal and loft insulation and solar panels on a roof slope normally do not. The area has 5 listed buildings; on a listed building solar panels and heat pumps are not permitted development at all and need planning permission and listed building consent. 775 homes inside the boundary have an energy certificate: 11.0% are solid-wall homes with no wall insulation, 56.9% heat with a gas boiler and 49.9% are rated D–G; 0 have a heat pump. EPC register November 2026; rules as at 21 October 2026.

Flats: 98% of the certified homes here are flats or maisonettes. Homes in a block of flats have no householder rights for alterations; heat pumps and solar have their own, tighter rules for blocks of flats.

Caveats
Certificates describe a home when it was assessed; 57% of these are from 2020 or later (latest 29 October 2026). “No insulation (assumed)” is the assessor's default for older walls.
The rules are England's national permitted development rules (General Permitted Development Order 2015, Schedule 2, as at 21 October 2026). They do not cover building regulations or a council's own conditions. This is not a planning decision: ask Bournemouth, Christchurch and Poole if in doubt.
Boundary: Bournemouth, Christchurch and Poole Council via planning.data.gov.uk (entity 44017448, reference BOSS, 10.0 ha); the council's appraisal or map. Homes are placed by the coordinates of their UPRN (OS Open UPRN); addresses are not shown.
