Boiler upgrade grant

Quick answer

The Boiler Upgrade Scheme is a UK Government grant towards installing low-carbon heating such as air source and ground source heat pumps in England and Wales.

Boiler Upgrade Scheme overview

Grants are paid to MCS-certified installers, who reduce your invoice by the grant amount. Levels are set by Government and may change.

Heat pump funding

Air source heat pumps are the most common type. Ground source heat pumps attract higher grants where suitable.

Frequently asked questions

Can I keep using gas for cooking?

Yes. Only the heating system is being replaced.

How long does install take?

Typically 2-5 days, plus survey.

What about new builds?

New builds are generally outside BUS, since they should be designed for low-carbon heating already.

How does my EPC affect eligibility?

Most major schemes prioritise EPC D-G homes. If your rating is unknown, you can still use our checker and confirm later.

Does this checker guarantee funding?
