Bristol breaks the pattern for conservation areas: 43.8% of homes here have uninsulated solid walls against 48.7% across all England's conservation areas, and the heat pump leader is suburban Stapleton and Frome Valley, even though the largest area is Clifton. In 20 of the 34 areas, Article 4 directions cover other matters, so windows, roofs, panels and pumps there follow the general rules for conservation areas.
Centre and suburbs
In Clifton, 68% of the 5,577 houses have solid walls without insulation, and there are 480 listed buildings. In Cotham and Redland, such walls account for 77% across 3,961 houses. The outskirts are different: in Brentry it is 3%.
Where the heat pumps are
According to the EPC register as of November 2026, there are 403 heat pumps in the areas: 115 across 2,530 houses in Stapleton and Frome Valley, 48 in Sea Mills. Check the boundary of your street on the area page or with the council. The rules are national, current as at 21 October 2026; this is not a planning decision, so if in doubt ask Bristol council.
