The Boiler Upgrade Scheme
- £7,500 towards an air source or ground source heat pump in England and Wales.
- £9,000 for eligible properties currently heated by oil or LPG, from 21 July 2026 to 31 March 2027.
- No income test. Your MCS-certified installer applies, and the grant comes off your quote.
- The government has also announced smaller grants for air-to-air heat pumps and heat batteries; check GOV.UK for the start date.

Running a heat pump cheaply
Heat pumps work best running steadily at lower temperatures, in a well-insulated home with correctly sized radiators. A specialist heat pump tariff or time-of-use tariff can cut running costs further. Ask your installer for a heat loss survey and a predicted efficiency (SCOP) figure.
Choosing an installer
Use an MCS-certified installer (required for the grant), get more than one quote, and ask for examples of similar homes they’ve fitted. Check the quote includes the cylinder, radiators, electrical work and commissioning.
