Solar panels, heat pumps and insulation in Watlands Park conservation area
In the Watlands Park conservation area (Newcastle-under-Lyme), 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 Newcastle-under-Lyme covers this area and removes permitted development rights for replacement windows and doors, and other alterations to the house, alterations to the roof (e.g. rooflights), so there these need planning permission too. 148 homes inside the boundary have an energy certificate: 46.6% are solid-wall homes with no wall insulation, 95.9% heat with a gas boiler and 79.7% 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; 49% of these are from 2020 or later (latest 26 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 Newcastle-under-Lyme if in doubt.
Boundary: Newcastle-under-Lyme Borough Council via planning.data.gov.uk (entity 44016214, reference CA21, 11.2 ha); the council's appraisal or map. Homes are placed by the coordinates of their UPRN (OS Open UPRN); addresses are not shown.
