Solar panels, heat pumps and insulation in All Saints, Whitefield conservation area
In the All Saints, Whitefield conservation area (Bury), 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 Bury covers this area but deals with other things (such as changes of use); it does not change the rules below. The area has 7 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. 118 homes inside the boundary have an energy certificate: 11.9% are solid-wall homes with no wall insulation, 96.6% heat with a gas boiler and 75.4% are rated D–G; 0 have a heat pump. EPC register November 2026; rules as at 21 October 2026.

Caveats
Certificates describe a home when it was assessed; 38% of these are from 2020 or later (latest 28 September 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 Bury if in doubt.
Boundary: Bury Metropolitan Borough Council via planning.data.gov.uk (entity 44015749, reference CA002, 19.5 ha); the council's appraisal or map. Homes are placed by the coordinates of their UPRN (OS Open UPRN); addresses are not shown.
