£9,000 heat pump grants: who actually qualifies

From April 2025, the Boiler Upgrade Scheme will offer households in England and Wales up to £9,000 towards a heat pump, a £1,500 increase on the current £7,500 cap. The change, first reported by Ideal Home, could cut the upfront cost of a typical air-source heat pump installation from around £14,000 to roughly £5,000 for a 3-bed semi. That is the kind of number that makes retrofit maths work for many more families.

As Ideal Home reported, the extra funding is part of the government’s push to install 600,000 heat pumps a year by 2028. But the headline figure hides the usual caveats: not every household qualifies, and the grant alone won’t fix a leaky home.

Who qualifies, and who doesn’t

The Boiler Upgrade Scheme is open to owner-occupiers and self-builders in England and Wales. Landlords and new-build developers are excluded. To get the full £9,000, you must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation. That means you either already have those measures installed, or you get them done before applying.

Ofgem, which administers the scheme, also requires the heat pump to be installed by an MCS-certified installer. The property must have a suitable outdoor space for the external unit, usually a metre from the nearest wall, and the heating system must be built to run at lower flow temperatures than a gas boiler. If your radiators are undersized, you may need to upgrade them, adding £1,500 to £3,000 to the total cost.

What it costs a typical 3-bed semi

Take a semi-detached house in Manchester, built in the 1970s, with 90mm loft insulation and cavity wall insulation already fitted. The EPC is a C. An air-source heat pump installation, unit, labour, new hot water cylinder, and radiator upgrades, comes to roughly £14,000. The £9,000 grant brings the household’s share to £5,000. Over 15 years, the Energy Saving Trust estimates annual heating savings of £285 compared with a gas boiler, assuming a seasonal coefficient of performance (SCOP) of 3.0.

The catch: if the same house had no cavity wall insulation and only 50mm in the loft, the EPC would be a D or E. The grant application would be rejected until those measures are installed. Insulating a cavity wall costs about £1,500 for a semi, and topping up loft insulation to 270mm runs roughly £500. That adds £2,000 to the upfront bill, but also cuts heat loss by up to 30%, improving the heat pump’s efficiency and your annual savings.

How the grant fits the bigger picture

The £9,000 figure is not a universal cheque. The scheme is capped at 50,000 installations per year across England and Wales, and demand is expected to exceed supply in the first few months. Ofgem confirmed to the press that applications will be processed on a first-come, first-served basis, so acting early matters.

Yet the grant alone does not solve the UK’s heat pump adoption problem. The Climate Change Committee estimates that 19 million heat pumps need to be installed by 2050 to meet net-zero targets. At current rates, roughly 60,000 installations a year, that target is decades off. The £9,000 grant is a nudge, not a silver bullet. What is missing is a coordinated programme of low-cost loans for insulation and heat pumps, similar to Scotland’s Warmer Homes Scotland scheme, which offers interest-free loans up to £15,000.

For now, the best advice is straightforward: check your EPC, fix the cheap insulation gaps first, then apply for the grant as soon as the window opens. The government has not yet confirmed the exact launch date, but April 2025 is the stated timeline. Book an MCS installer now, lead times are already running 8 to 12 weeks in most regions.
