Quick answer: The headline UK energy grant in July 2026 is the £7,500 Boiler Upgrade Scheme, which has supported nearly 80,000 heat pumps in four years. The Warm Homes: Local Grant adds up to £30,000 for eligible lower-income households, and 0% VAT on solar, batteries, heat pumps and insulation runs until March 2027.
This page separates two kinds of number: verified scheme facts from GOV.UK, and uptake statistics from DESNZ official releases and MCS certification data. Where a figure is analysis rather than a primary source — such as Nesta’s four-year review — we say so and link it.

What the £7,500 grant does to heat pump costs, by region
Combining the BUS grant with our modelled regional heat pump costs shows the out-of-pocket picture across England and Wales (rows for Scotland and Northern Ireland are shown for cost comparison only — BUS applies in England and Wales; Scotland has Home Energy Scotland and NI has NISEP). Modelled figures per our methodology.
| Region | Modelled heat pump cost | After £7,500 BUS grant |
|---|---|---|
| UK average | £11,014 | £3,514 |
| London | £13,217 | £5,717 |
| South East | £12,336 | £4,836 |
| East of England | £11,675 | £4,175 |
| South West | £11,565 | £4,065 |
| West Midlands | £10,794 | £3,294 |
| East Midlands | £10,684 | £3,184 |
| Scotland | £10,573 | £3,073 |
| Yorkshire & the Humber | £10,463 | £2,963 |
| North West | £10,463 | £2,963 |
| Wales | £10,353 | £2,853 |
| North East | £10,243 | £2,743 |
| Northern Ireland | £10,133 | £2,633 |
Note the contrast with the official DESNZ median of £13,041 for BUS-funded installations in 2025/26: grant-funded jobs skew larger and more complex than our all-comers modelled average, which is exactly the kind of gap a methodology note should admit to.
How to claim
For BUS, an MCS-certified installer applies on your behalf via GOV.UK, and the application date sets the grant amount — which matters for the oil/LPG £9,000 window opening 21 July 2026. Our BUS guide walks through the process, the Warm Homes: Local Grant guide covers council applications, and every grant still open in 2026 is the full checklist.
