Postcode area BN

Explore heat-pump installation costs and potential bill savings for every postcode district in the BN area. Each district page provides a tailored estimate for an air-source heat pump, compares running costs vs gas or oil, and explains Boiler Upgrade Scheme (BUS) support in plain English. Use the links below to pick your district, review typical price bands, adjust tariffs to your own rates, and see what affects quotes (property size, insulation, SCOP). Figures are indicative; a qualified MCS-certified installer will confirm final pricing and grant eligibility.
