The Boiler Upgrade Scheme (BUS) is live!

Note: This scheme is not run by Action Surrey - full information and how to apply can be found here on the government's website.

If you are planning to replace your gas boiler, you may be eligible for a grant towards a  low carbon heating system such as a heat pump or biomass boiler.  The scheme is open to eligible domestic and small non-domestic properties in England and Wales till 2025.


  • Must be the owner of the property. Also applicable to landlords.
  • An updated energy performance certificate (EPC), with no recommendations for loft or cavity wall insulation.

What you will receive

  • £5000 off for the cost of an air source heat pump
  • £5000 off for the cost of a biomass boiler
  • £6000 off for the cost of a ground source heat pump 

How does it work?

  • Find an MCS certified installer  that is able to do the installation (the quality assurance will mean that the correct standards are used for the installation) 
  • The installer will inform if the works are possible under the grant.
  • Agree a quote for the installation
  • The installer will apply for the grant
  • You will confirm that the installer is acting on your behalf when contacted by Ofgem (office of gas and electric markets) 

Heat pumps and Biomass boilers

Heat pumps are a form of low carbon technology, they capture heat from the outside and transfer it to the home. It uses electricity but the amount of output energy to your home is larger than the power you need to run the unit, so it is a highly efficient system. For a more in depth understanding including different types, please visit the energy saving  guide to heat pumps.

Biomass heating systems use wood or other organic materials as a fuel to heat up water. It could be an option if you already have a very old heating system, but can require an air quality assessment and are more maintenance than a gas boiler. You can find out here.
