Federal 25C credit ended 31 Dec 2025 · UK £9,000 uplift live to 31 Mar 2027

Every heat pump grant, actually checked.

The money moved. The US federal credit is gone, so what you can claim now depends on your state — and in Britain a new £9,000 grant just opened for homes off the gas grid. We track both, against the source documents.

US: what your state offers → UK: grants explained

The short version: In the United States, the federal Energy Efficient Home Improvement Credit (Section 25C) — up to $2,000 a year toward a heat pump — covers improvements made through 31 December 2025. Install in 2026 and there is no federal credit to claim; state and utility programmes are what is left, and they differ enormously. In the United Kingdom, the Boiler Upgrade Scheme pays £7,500 toward an air-to-water or ground source heat pump in England and Wales — and from 21 July 2026 an eligible off-gas-grid home can get £9,000 instead, until 31 March 2027.

Start where you live

UNITED STATES

The federal credit is gone. Your state may still pay.

  • Section 25C applied to improvements made through 31 Dec 2025 — confirmed by the IRS
  • What remains is state and utility programmes, each on its own timetable
  • Many are income-qualified or waitlisted — we say so plainly where that is true

Why another grant site

Because the numbers on most pages are old. While writing this page we found the government’s own consumer guide at GOV.UK still listing the Boiler Upgrade Scheme grants without the £9,000 off-gas-grid uplift that Ofgem — the body that actually administers the scheme — had already published. If the official consumer page can lag, the blogs copying it lag further.

So we do the boring thing. Every figure on this site is traced to the organisation that sets it: the IRS for federal tax credits, Ofgem and DESNZ for the Boiler Upgrade Scheme, and the individual state energy offices for US state programmes. Each page carries the date we last checked it and a link to the source. Where we have not verified something, we leave it out rather than guess.

What we are still checking

US state programmes are being verified one at a time, directly against each state energy office. We publish a state page when the source confirms the numbers — not before. If a programme you are waiting on is missing, that is why.
