Boiler Upgrade Scheme - FAQs

The government boiler upgrade scheme was launched in April 2022. It will provide a boiler upgrade grant to help owners of domestic and small non-domestic properties in England or Wales with the upfront cost of installing low carbon heating systems, such as heat pumps. It will run from 2022 to 2025.

The scheme will provide £7,500 towards the installation of an air source heat pump.

Find out more about the scheme on the government website.

Am I eligible for the Boiler Upgrade Scheme?

You may be eligible for the Upgrade Boiler Scheme if you:

• live in England or Wales
• own your property (whether this is a home or a small non-domestic property)

The property will need to have:

• an installation capacity up to 45kWth (this covers most homes)
• a valid Energy Performance Certificate (EPC) with no understanding recommendations for loft or cavity wall insulation (unless you have an insulation exemption). You can find out if you have a valid EPC here.

New build properties will not normally be eligible. The only exception is if you're building your own home.

To be eligible for the scheme, the commissioning date of the heating system must be on or after 1st April 2022. 

Your installer will advise whether a low carbon heating system is suitable for your property.

You can still apply for BUS even if you have received separate funding for energy efficiency upgrades, such as insulation, doors or windows. 

You are not eligible for BUS to replace an existing low carbon heating system. Funding is only available if you are fully replacing an existing fossil fuel systems such as oil, gas or direct electric. 

Check if you are eligible on the government website.

How does the Boiler Upgrade Scheme work?

Your installer must be MCS certified for the work to be eligible for the BUS grant. Your installer will apply for the grant on your behalf and then take the value of the grant off the price you pay.

We recommend you get quotes from more than one installer to make sure you're getting the best value for money. 

1. Check you are eligible for the Boiler Upgrade Scheme on the government website.  Then find an MCS certified installer in your area that is able to carry out the work. MCS is a quality assurance scheme that ensures installers are competent, and the products they use meet the correct standards. Check here to see if your local Baxi Works installer is MCS certified.
2. Your installer advises you on whether an installation is eligible for a grant.
3. You agree a quote for the installation.
4. The installer applies for the grant.
5. You confirm that the installer is acting on your behalf when you’re contacted by Ofgem.
6. When the installation has been completed, your installer will take the amount of the grant off the price you pay.
