about the boiler upgrade scheme (BUS)

OfGem Logo

what is it?

The Boiler Upgrade Scheme is a financial incentive to aid the decarbonisation of buildings by encouraging people to replace (or in the case of self-builders install straight away) existing fossil fuel systems with low carbon heating systems.

As of Monday 23 October 2023, the government will provide £7,500 to overcome the upfront costs of installing either an air-source heat pump, a biomass boiler or a ground-source heat pump under the scheme.

who's it for?

The scheme is open to properties that:

  • are domestic or small non-domestic
  • are located in England or Wales
  • with a heating requirement of no more than 45kWth
  • are a single property which is capable of getting a domestic Energy Performance Certificate (EPC) . The EPC is the proof Ofgem needs that the property is assessed as a domestic ‘dwelling‘. It gives information about a property‘s energy use, plus recommendations on how to reduce energy and save money. It‘s required every time you buy, sell or rent a property.
The new heating system must:
  • be capable of meeting the full space heating and hot water requirements of the property
  • replace an existing fossil fuel heating system (unless a self-build)
  • meet certain technical standards, usch as minimum effiiciency requirements
  • have been commissioned from April 2022 onwards.

how do you apply?

To apply you will need to be the homeowner (or a self-builder) and have a valid EPC with no outstanding recommendations for loft or cavity wall insulation. The system must be correctly sized and fitted by a Microgeneration Certification Scheme (MCS) accredited installer who will also apply for the grant on your behalf after you have accepted their quote. You will need to confirm the installer is acting on your behalf when you are emailed by Ofgem.

You can get more information from the Government website.
