Business Wales published a page on applying for the Boiler Upgrade Scheme on 22 September 2026, setting out that grants of up to £9,000 are available in Wales and England towards the cost of replacing fossil fuel heating systems with a heat pump1.
The page states that the grant can be used to replace a fossil fuel heating system in a building used for a business or a home, and lists the systems it covers as oil, gas, electric and LPG (liquefied petroleum gas)1. It directs readers to GOV.UK for the scheme overview and to the Clean Energy campaign's heat pump page for further information1.
"The UK Government is offering grants of up to £9,000 in Wales and England to help cover the cost of installation."
The page also carries the Business Wales helpline number, 03000 6 03000, with lines open 10am to 4pm Monday to Friday1. It does not set out eligibility conditions, the application process, or how the grant is paid; those details are not reported on the page, which points to GOV.UK instead1. The page also mentions the Green Growth Pledge, a separate scheme for Welsh businesses1.

Why it matters for households
The figure of up to £9,000 is the headline number a household in Wales weighing up a heat pump will meet first, and the page confirms the scheme applies to homes as well as business premises1. For a home currently heated by oil or LPG, where there is no gas mains connection to fall back on, the grant is the main published support towards the upfront cost of switching, and the page names both fuels as eligible1. The wider context is set out in our guide to grants, schemes and household energy independence, and the Wales-specific figure is covered in how much is the heat pump grant in Wales.
The page does not say what a heat pump costs to install, so the grant cannot be read as a full price; the net cost depends on the property and the installer, and our guide to heat pump cost with a Boiler Upgrade Scheme grant covers that ground. Households with an existing gas boiler, and whether they can still claim, are dealt with in can I get the Boiler Upgrade Scheme grant if I have a gas boiler. The mechanics of claiming are set out in how the Boiler Upgrade Scheme application works, and the grant amount itself in how much is the Boiler Upgrade Scheme grant. For households in England, boiler and heating grants in England covers the same scheme from that side of the border, while boiler and heating grants in Wales sets out the Welsh position.
