Solar panels, heat pumps and insulation in Fulford Village conservation area
In the Fulford Village conservation area (York), 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. An Article 4 direction published by York covers this area but deals with other things (such as changes of use); it does not change the rules below. The area has 12 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. 418 homes inside the boundary have an energy certificate: 39.7% are solid-wall homes with no wall insulation, 79.9% heat with a gas boiler and 58.1% are rated D–G; 2 have a heat pump. EPC register November 2026; rules as at 21 October 2026.

Caveats
Certificates describe a home when it was assessed; 55% of these are from 2020 or later (latest 25 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 York if in doubt.
Boundary: City of York Council via planning.data.gov.uk (entity 44014471, reference 3120, 33.4 ha); the council's appraisal or map. Homes are placed by the coordinates of their UPRN (OS Open UPRN); addresses are not shown.
