What is the Boiler Upgrade Scheme (BUS)?

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:


  • £5,000 off the cost and installation of an air source heat pump
  • £5,000 off the cost and installation of a biomass boiler
  • £6,000 off the cost and installation of a ground source heat pump


The grant will only cover biomass boilers in rural locations and in properties that are not connected to the gas grid.
