Government Boiler Upgrade Scheme - Global Energy Systems

Grants and funding for air source heat pumps

If you live in England or Wales you can apply for £5,000 towards your new air source heat pump

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a UK government scheme that aims to help reduce carbon emissions by encouraging householders in England and Wales to switch to low-carbon heating systems such as air source heat pumps in place of existing gas or oil heating. The scheme offers up to £5,000 to assist with the upfront costs of upgrading to air source heat pumps. The scheme will run from 2022 to 2028 and is not means-tested.

You could be eligible if:

  • Your property is in England or Wales
  • You own the property - whether this is your home, a holiday let or small commercial property
  • You are replacing the old fossil fuel or electric heating system with a renewable heating system such as an air source heat pump
  • You are not replacing a heat pump or previous renewable system
  • The property has a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation

If you live in Scotland, you can apply for an interest-free loan to pay for energy efficiency improvements upfront, including air source heat pumps. There are also grants for low-income households in Scotland and in Wales.
