The Boiler Upgrade Scheme (BUS) is a UK government initiative that provides homeowners in England and Wales with grants of up to £7,500 towards the cost of installing a heat pump. If you're considering switching from a gas or oil boiler to a more efficient heating system, this grant can significantly reduce the upfront cost.

Who Is Eligible for the Boiler Upgrade Scheme?

To qualify for the BUS grant, your property must meet several key criteria. Understanding these requirements before you start the process will save you time and ensure a smooth application.

Property Requirements

Your property must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation. The property must be an existing building — new builds are not eligible. You must also own the property, although both owner-occupiers and private landlords can apply.

Installation Requirements

The heat pump must be installed by an MCS certified installer, and the system itself must be MCS certified. The installer handles the grant application on your behalf through the Ofgem portal, so choosing the right installer is crucial.

How Much Can You Get?

The grant amounts were increased in October 2024:

  • Air source heat pumps: up to £7,500
  • Ground source heat pumps: up to £7,500
  • Biomass boilers (in qualifying rural areas): up to £5,000

The grant is paid directly to your installer, who deducts it from your total quote. This means you only pay the remaining balance.

How to Apply: Step by Step

The application process is straightforward when you work with an experienced MCS certified installer:

  1. Get a home energy survey — Your installer will assess your property and recommend the right system size
  2. Receive a detailed quote — This should include the full cost minus the BUS grant amount
  3. Your installer applies to Ofgem — They submit the application through the official portal
  4. Ofgem issues a voucher — This is typically processed within a few weeks
  5. Installation goes ahead — Once the voucher is confirmed, installation is booked in
  6. Grant is paid to your installer — Ofgem pays the installer directly after commissioning

Tips for Maximising Your Grant

Make sure your EPC is up to date and that you've addressed any insulation recommendations first. Getting multiple quotes from different MCS certified installers will help you find the best value, and our directory makes it easy to compare local installers in your area.
