Government Scheme
Boiler Upgrade Scheme
Grants of up to £7,500 to replace fossil fuel heating with air source heat pumps or other low-carbon alternatives in England and Wales.
What is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is a government initiative offering upfront capital grants to help homeowners in England and Wales replace fossil fuel heating systems — such as gas and oil boilers — with low-carbon heat pumps.
Since its launch in 2022, the scheme has been extended and the grant increased to £7,500 for air source heat pumps. BUS is designed to make the switch to renewable heating affordable and accessible, helping the UK meet its net-zero targets while reducing household energy costs.

How It Works
Get an EPC
Ensure your property has a valid EPC. If loft or cavity wall insulation is recommended, this should be addressed first.
Choose an MCS installer
An MCS-certified installer surveys your home, designs the system, and applies for the grant on your behalf.
Grant approved
Ofgem processes the application and confirms the grant. The voucher is valid for 3 months.
Installation
The installer fits the heat pump and the £7,500 grant is deducted from your bill. You pay only the remaining balance, if any.
