Solar panels, heat pumps and insulation in Woodhouse - Hanover Square / Woodhouse Square conservation area
In the Woodhouse - Hanover Square / Woodhouse Square conservation area (Leeds), 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 Leeds covers this area but deals with other things (such as changes of use); it does not change the rules below. The area has 16 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. 362 homes inside the boundary have an energy certificate: 42.3% are solid-wall homes with no wall insulation, 51.7% heat with a gas boiler and 45.6% are rated D–G; 1 has a heat pump. EPC register November 2026; rules as at 21 October 2026.

Caveats
Certificates describe a home when it was assessed; 46% of these are from 2020 or later (latest 13 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 Leeds if in doubt.
Boundary: Leeds City Council via planning.data.gov.uk (entity 44014908, reference CA012, 6.2 ha); the council's appraisal or map. Homes are placed by the coordinates of their UPRN (OS Open UPRN); addresses are not shown.
