The Boiler Upgrade Scheme is a UK government grant that takes £7,500 straight off the cost of an air source or ground source heat pump. It is not a loan, it is not means-tested, and you never have to claim it back — your installer applies to Ofgem and the money comes off your invoice. We check whether your property qualifies, tell you the honest balance you would pay, and handle the application.
Air source or ground source heat pump. Deducted before you pay — you are never out of pocket waiting for a refund.
Properties heated by oil or LPG with no mains gas connection can get an uplifted grant, until 31 March 2027.
Your income is irrelevant. The scheme is open to every eligible property owner in England and Wales.
The Boiler Upgrade Scheme (BUS) is run by Ofgem on behalf of the Department for Energy Security and Net Zero. It exists to help owners of homes and small commercial premises in England and Wales replace fossil fuel heating with a heat pump. The mechanism matters: your MCS-certified installer applies for the voucher before the work starts, and the grant is taken off the final bill. You pay the balance and nothing more.
Confirm eligibility against the current Ofgem rules · Survey the property and size the system honestly · Tell you the exact balance you would pay before you commit · Apply for the voucher and track it to issue · Install to MCS standards · Deduct the grant from your invoice · Hand over commissioning paperwork and your MCS certificate.
Answer five questions. This is an indicative check against the main scheme conditions — it is not an Ofgem decision, and we confirm your position properly before anyone commits to anything.
1. Is the property in England or Wales, and do you own it?
2. Is it heated now by a fossil fuel system (mains gas, oil, LPG, coal) or by electric heating that is not a heat pump?
3. Does the property have a valid EPC (issued in the last 10 years)? Any rating A–G is fine.
4. Have you already had a Boiler Upgrade Scheme or Renewable Heat Incentive grant for a heat pump at this property?
5. Is this an existing building rather than a brand-new self-build you are still constructing?
The scheme is installer-led. You never fill in an Ofgem form — but you should understand each stage, because the order matters and the voucher must be secured before work begins.
You tell us the property type, the current heating system and whether there is a mains gas connection. We check it against the live scheme rules and come back with a straight answer: eligible, not eligible, or eligible once one thing is sorted (a lapsed EPC is the most common fixable blocker — and we can lodge one for you).
⚡ We respond to every enquiry within 2 hoursWe calculate the property's heat loss room by room and size the heat pump to it. This is the stage where corners get cut in this industry — an undersized unit leaves you cold, an oversized one cycles and costs you money. We also check whether your existing radiators and hot water cylinder can carry the lower flow temperatures, because that is where unexpected cost appears.
You get one figure with the grant already deducted, itemised so you can see what is the heat pump, what is pipework and radiators, and what is the cylinder. If additional works are needed, they appear here — not as a surprise mid-installation. If we think a heat pump is the wrong answer for your property, we say so at this stage.
💷 Fixed quote — the price we quote is the price you payWith your consent, we submit the voucher application before any work starts. Ofgem contacts you directly to confirm you asked for the installation — that confirmation is a scheme requirement, and the application cannot proceed until you respond. Vouchers have a fixed validity window, and we schedule the work inside it.
The installation is carried out by an MCS-certified installer, which is a condition of the grant. Most domestic heat pump installations take a few days on site. You receive the MCS certificate and commissioning records, which you will need for warranty, for any future EPC, and for your own file.
We redeem the voucher and the grant is deducted from what you pay. You settle the balance only. If you also want solar, we can advise on pairing the two so more of the heat pump's electricity comes from your own roof.
Plenty of advertising implies a heat pump is free. It is not, and we would rather tell you that now than after a survey. Here is where the money and the limits actually sit.
£7,500 covers a substantial share of a typical domestic installation, but there is a balance to pay. That balance depends on system size, your existing radiators and cylinder, and any additional works. We give you the number before you commit.
A heat pump runs at a lower flow temperature than a gas boiler. In a poorly insulated property with small radiators, the honest answer is often insulation first. We will tell you if that is your situation.
If the property has already had a Boiler Upgrade Scheme or Renewable Heat Incentive payment for a heat pump, it cannot claim again.
Government funds the scheme in annual budgets and grants are issued first come, first served. That is a real reason not to sit on a decision — but not a reason to rush a bad installation.
From 1 October 2030, privately rented homes in England and Wales must reach EPC C — for existing tenancies as well as new ones, subject to a £10,000 per-property cost cap. Replacing a fossil fuel system with a heat pump is one of the larger single moves available on an EPC, and the Boiler Upgrade Scheme is the government paying for a substantial part of it. If you are a landlord planning for 2030, this grant and that deadline belong in the same conversation.
Tell us your property type, your current heating and whether you have a mains gas connection. We will confirm whether the grant applies, and give you the honest balance — before anyone books a survey.
