Heat pumps, the targeted £9,000 grant, and the standard £7,500 rate

Updated: August 2026

Heat pumps are the future of home heating in the UK. The standard £7,500 Boiler Upgrade Scheme grant can reduce the upfront cost of an eligible installation in England or Wales. Heat pumps deliver 3-4 units of heat for every unit of electricity used, making them far more efficient than gas boilers.
