Boiler Upgrade Scheme 2025: Your Complete Guide to Heat Pump Grants

If you're thinking about replacing your gas boiler with a heat pump, the Boiler Upgrade Scheme (BUS) could save you up to £7,500 on installation costs. Originally launched in 2022, the scheme has been extended and the grant amount increased — making 2025 one of the best times to make the switch to renewable heating.

What Is the Boiler Upgrade Scheme?
