FAQs
Heat Pumps in Lewes: FAQs
Do you provide heat pumps across all of Lewes?
Yes, we cover the BN7 postcode area in full, including Cliffe, Southover, Landport, Nevill, Malling, Wallands.
Will I need to replace my radiators for a heat pump?
Often, yes — heat pumps run most efficiently at lower flow temperatures than a gas boiler, so existing radiators are sometimes undersized for the new system. We assess this during the heat loss survey and specify any radiator or underfloor heating changes needed.
What is the Boiler Upgrade Scheme (BUS) grant?
It's a government grant offering a fixed contribution toward the cost of installing an air-source or ground-source heat pump in England and Wales. Eligibility depends on the property and installer, so we advise on the likely position but can't guarantee an award.
How does South Downs National Park status affect building work in Lewes?
Development within the National Park is assessed with particular regard to landscape character and setting, alongside normal planning policy. Combined with the town's conservation area and listed building status, this means early advice is particularly valuable in Lewes.
