Replacing an old or broken heating system is a big expense, and there’s grant support to help — especially if you’re moving to low-carbon heating. Here’s what you can get and how it works.
The Boiler Upgrade Scheme
The main grant for heating is the Boiler Upgrade Scheme, which gives £7,500 towards an air- or ground-source heat pump, or £5,000 towards a biomass boiler, in England and Wales. Your MCS-certified installer applies on your behalf and takes the grant off the price. It’s open to most homeowners and small landlords replacing fossil-fuel heating.
What about a replacement gas boiler?
Grants for like-for-like gas boilers are very limited. The ECO4 scheme, which could replace broken heating for low-income households, ends on 31 December 2026, and Consumer Rights can no longer help with ECO4 applications — see what to do now about ECO4. Lower-income households in England may still get help through the Warm Homes: Local Grant.
What to do next
Check your eligibility, get quotes from an MCS-certified installer, and see all the options on our home energy grants page. For your rights when the work is done, see heating and boilers.
