What is the boiler upgrade scheme?

Understanding the government's initiative for UK property owners

The Boiler Upgrade Scheme (BUS) is a government initiative designed to help property owners in England and Wales make the switch to low-carbon heating. Launched on 23 May 2022, the scheme provides a one-off grant to reduce the upfront cost of installing an air source heat pump, ground source heat pump, or, in some rural areas, a biomass boiler. It's not a free boiler upgrade scheme, but a substantial grant to make sustainable heating more accessible. The goal is simple: encourage more homes to adopt renewable heating technologies, cut carbon emissions, and help the UK reach its net-zero targets. Ofgem administers the scheme, processing voucher applications and making payments to installers. The scheme is currently funded until 31 December 2027.

Boiler upgrade scheme eligibility: can you get a grant?

Key requirements for property owners in England and Wales

To qualify for the Boiler Upgrade Scheme grant, you'll need to meet specific criteria. The scheme is open to property owners in England and Wales, including landlords. Here are the key requirements for boiler upgrade scheme eligibility:

• Property type: Your property must be an existing domestic or small non-domestic building. New builds and social housing are generally excluded, except for self-builds.
• Ownership: You must own the property you're applying for.
• Valid EPC: Your home needs a valid Energy Performance Certificate (EPC) issued within the last 10 years. As of 8 May 2024, there are no minimum insulation requirements for applications made after this date.
• Existing heating system: The grant is for replacing an existing fossil fuel heating system (like a gas, oil, LPG, or electric boiler). It cannot be used to replace an existing low-carbon heating system.
• Installer: Your chosen low-carbon heating system must be installed by an MCS-certified installer.

The scheme does not apply to properties in Scotland, as they have their own support programmes.

How to apply for the boiler upgrade scheme grant

Your step-by-step application process

Applying for the Boiler Upgrade Scheme grant is simpler than you might think, as your installer handles most of the heavy lifting. Here's how to apply for boiler upgrade scheme support:

1. Check your eligibility: First, confirm your property and existing heating system meet the criteria.
2. Get quotes: Contact several MCS-certified installers for quotes on installing a heat pump or biomass boiler. They will assess your home's suitability and recommend the best system.
3. Installer application: Once you accept a quote, your chosen installer will apply for the Boiler Upgrade Scheme grant on your behalf. They will deduct the grant amount from your total installation cost, so you only pay the difference.
4. Installation: The installer will then proceed with the installation of your new low-carbon heating system.
5. Grant paid: Ofgem pays the grant directly to your installer after the installation is complete and confirmed.

The current grant values are £7,500 for air source heat pumps, £7,500 for ground source heat pumps, £5,000 for biomass boilers, and £2,500 for air-to-air systems2. These grant levels were increased in October 2023.

Our detailed consumption insights, including hourly usage data, allow you to pinpoint exactly when and how much energy your heat pump is using.
