Boiler Upgrade Scheme

Location notice

Please note that this page contains information and links most relevant for people living in England, Wales.

We're waiting to hear from the new UK Government on the future of this funding. We'll update this page as soon as we get any new information.

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a government grant for people in England and Wales who want to install a heat pump or a biomass boiler.

How much funding is available?

The Boiler Upgrade Scheme covers three low carbon heating systems. The level of grant towards a heat pump increased from £5,000 to £7,500 on 23 October 2023.

Applications to the BUS tripled the week after the government increased the grant, helping to address one of the barriers to adopting the technology.


What happens if I applied to the Boiler Upgrade Scheme before 23 October 2023?

If you applied to the BUS before this date, and your installer hasn’t yet fitted your new heat pump, talk to them. The government says you can ask your installer to cancel your initial grant and reapply to claim the increased amount.

How will I know which low carbon heating system is right for my property?

Your installer can advise whether a heat pump or biomass boiler is suitable for your property. Although you’re not required to have home insulation to qualify for the BUS, the installer may recommend improving the energy efficiency of your property first.

Read our advice on loft insulation and cavity wall insulation to help improve your property’s energy efficiency before installing a low carbon heating system.

Who can apply to the Boiler Upgrade Scheme?

The BUS is open to homeowners and owners of small business properties in England and Wales only.

To apply, you’ll need to:

  • Own your property (this can be a home or a small business property).
  • Have a valid Energy Performance Certificate (EPC).
  • Have a property with an installation capacity up to 45kWth (kilowatt-thermal). This covers most homes.

How can I apply to the Boiler Upgrade Scheme?

  1. Find an MSC certified installer in your area who can carry out the work. We recommend you contact three installers for quotes.
  2. The installer will tell you if you’re eligible for a BUS grant. 
  3. Agree a quote with your installer. The value of the grant from the BUS will be deducted as part of the quote.
  4. The installer will apply for the grant and carry out the work.
