Grants & Funding
Every UK heat pump grant, in one neutral place.
Four routes to a cheaper heat pump installation, depending on where you live and what you earn. We've laid out the eligibility, amounts and deadlines for each.

Which grant applies where you live
The UK doesn't run one heat pump grant — it runs several, and which one is yours depends on which nation the property is in. Find yours below.
England Use the Boiler Upgrade Scheme — £7,500 toward an air source or ground source heat pump, closing 31 December 2027.
Wales The Boiler Upgrade Scheme covers Wales on identical terms to England — same £7,500, same deadline, same MCS-installer route. Low-income households can also check the separate Warm Homes Wales (Nest) scheme.
Scotland BUS does not apply here. Scottish homeowners use Home Energy Scotland heat pump funding instead — cashback plus an interest-free loan, run by the Energy Saving Trust for the Scottish Government.
Northern Ireland Neither BUS nor Home Energy Scotland cover Northern Ireland — funding is arranged through Northern Ireland's own, separate energy efficiency schemes rather than either of these routes.
Boiler Upgrade Scheme (BUS)
£7,500 toward an air source or ground source heat pump in England and Wales. The main UK grant. Closes 31 Dec 2027.
ECO4 (Energy Company Obligation)
Free or subsidised installs for low-income households. Means-tested. Energy suppliers fund it, not government.
Home Energy Scotland
Up to £38,500 in loans plus £7,500 cashback for Scottish residents. Separate from BUS. Run by Energy Saving Trust.
Warm Homes Wales (Nest)
Free improvements (including heat pumps) for low-income homes in Wales — plus the full £7,500 BUS grant most Welsh homeowners overlook.
Grants — frequently asked questions
Can I combine multiple grants?
In some cases, yes. ECO4 and BUS can sometimes layer — for example, ECO4 may pay for insulation upgrades that allow you to qualify for BUS. You cannot, however, receive two grants for the same installation. Your installer is best placed to model the combination for your case.
How long does it take to receive the BUS grant?
You do not receive the money personally. Your MCS installer applies on your behalf through the Ofgem portal, and the grant is deducted from your invoice. Approval typically takes 2–4 weeks from application.
Is the £7,500 amount changing?
It was raised from £5,000 to £7,500 in October 2023. There is no announced further change. Government policy can shift quickly, so we update this page within seven days of any official announcement.
I live in Wales — do I use BUS or the Welsh Nest scheme?
Often both are worth checking. The Boiler Upgrade Scheme explicitly covers England and Wales — the same £7,500 grant, same rules, no reduced amount for Wales. Warm Homes Wales (Nest) is a separate, means-tested route for low-income households that can fund free improvements including a heat pump. If you don't qualify for Nest, you may still be fully eligible for BUS. See our full breakdown in the Wales grants guide below.
I live in Scotland — does the £7,500 BUS grant apply to me?
No. BUS covers England and Wales only. Scottish homeowners use Home Energy Scotland instead, which offers up to £7,500 cashback plus an interest-free loan of up to £38,500 — often more generous than BUS. See the dedicated Home Energy Scotland page for full eligibility.
