The UK's Boiler Upgrade Scheme hit a record in August 2026, with the highest number of heat pump vouchers issued in a single month. The scheme offers £7,500 off air source heat pumps and £9,000 for certain off-grid properties, as well as support for biomass boilers in rural areas. The surge comes as global energy prices rise due to conflict in the Middle East, pushing households toward electrification. Eligibility requires replacing a fossil fuel heating system, having a valid EPC, and using an MCS certified installer. New builds and social housing are excluded. The scheme runs until March 2027, and the government has published the latest statistics showing a 40% increase in vouchers compared to the same period last year. For more details, see the official guidance on the Boiler Upgrade Scheme.
