Owners of listed homes face bills of more than £50,000 to install a heat pump. The Government has promoted this new heating technology and offers grants for their installation.
But the grants will make little difference to historic properties, which face much higher bills because of the costs of installing insulation to make a heat pump work efficiently. On an unlisted property the pump and installation cost £12,000 to £15,000. Strict conservation rules mean planning permission is required before an air source heat pump can be installed in a listed property, adding to the costs.
Central Bath is all Grade II* listed. The Georgians are – largely – divided up into flats. You can’t put anything on the outside of the building. Grade II*, d’ye see? Sky dishes even, nope!
It’s also all 4 inch ashlar construction, double glazing not allowed, no cavity and so on.
So heat pumps are just right out, aren’t they?
