How British Gas heat pump finance works in 2026
British Gas offers a structured finance package for heat pump installations built to spread the cost over a period you choose. The core offer is 0% APR finance for either 12-month or 24-month terms, with longer-term options available at standard interest rates for those who need lower monthly payments.
The finance covers the total installation cost minus the £7,500 Boiler Upgrade Scheme (BUS) grant, which British Gas claims on your behalf as part of the process. This means you only finance the net amount after the grant is applied. Monthly payments typically start from approximately £85 to £150 depending on the system size and the repayment term you select (British Gas, 2026).
No upfront payment is required during the 0% APR period, but the full balance must be cleared by the end of the term or the standard APR applies to any remaining amount. The finance is arranged through British Gas’s panel of lenders, all regulated by the Financial Conduct Authority, so you should check the specific credit terms offered to you.
British Gas heat pump costs vs independent installer costs, side by side
Comparing costs between British Gas and an independent MCS-certified installer reveals a narrower gap than many homeowners expect. British Gas’s typical installed price range is £10,500 to £16,500 before the BUS grant, which reduces to £3,000 to £9,000 after the £7,500 deduction. Independent MCS-certified installers typically quote £12,000 to £18,000 before the grant, leaving a net cost of £4,500 to £10,500 after the grant (Energy Saving Trust, 2026).
British Gas includes a 10-year parts and labour warranty on all heat pump installations, while independent installers typically offer between 2 and 10 years depending on the manufacturer and the specific installer’s terms. British Gas uses Daikin and Vaillant units exclusively, whereas independent installers offer a broader choice of brands including Mitsubishi, Samsung, and Panasonic.
For smaller properties, typically 2 to 3 bedroom homes, the price difference narrows further, with British Gas approximately £500 to £1,500 cheaper on like-for-like system specifications. This is partly because British Gas’s volume purchasing power reduces unit costs, and partly because their standard installation scope is more tightly defined.

Can you get British Gas heat pump finance with 0% APR in 2026?
Yes, British Gas offers 0% APR finance for 12-month and 24-month terms on heat pump installations in 2026. This is a promotional balance transfer arrangement rather than a traditional loan, meaning the full balance must be cleared by the end of the promotional term or the standard APR applies to any remaining amount.
Eligibility depends on your credit score, property type, and whether you own the home, the 0% offer is not available for rented properties. The 0% APR option is available for all heat pump types British Gas installs, including air source, ground source, and hybrid systems. You must have the BUS grant approved before finance is finalised, but British Gas handles the application process on your behalf.
Eligibility criteria for British Gas heat pump finance
You must be a homeowner with a UK property, tenants and landlords are not eligible for the finance offer. Your property must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation, as this is a condition of the BUS grant (GOV.UK, 2026).
You must pass a credit check, British Gas uses Experian, and a poor credit score may result in a higher APR or outright rejection. The property must have suitable outdoor space for the heat pump unit, typically requiring at least one metre of clearance on at least one side. British Gas also requires a site survey before finance approval, during which they assess your existing heating system, pipework, and radiator sizing to ensure compatibility.
How to verify a British Gas heat pump installer
All British Gas heat pump installers are MCS-certified. You can verify this by checking the MCS Installer Database at mcs-certified.com using the specific installer name assigned to your project. British Gas also holds TrustMark registration, which you can verify via the TrustMark website (TrustMark, 2026).
For hybrid systems or existing boiler removal, installers are also Gas Safe Registered. British Gas provides a 10-year insurance-backed guarantee on all heat pump installations, underwritten by a third-party insurer. If you choose a non-British Gas installer, you lose access to the 0% finance offer but can still claim the £7,500 BUS grant independently through the standard application process.

British Gas heat pump finance vs other lenders, rates and terms compared
British Gas’s 0% APR offer for 12 to 24 months is cheaper than typical personal loan rates, which range from 7% to 15% APR for the same period depending on your credit profile. For longer terms of 3 to 5 years, British Gas’s 9.9% APR is competitive with high-street personal loans, which typically charge 6% to 12% APR for similar amounts.
Specialist green finance providers, such as Ecology Building Society and lenders affiliated with the Green Finance Institute, offer rates from 4% to 7% APR for heat pump installations. However, these lenders require you to claim the BUS grant yourself, adding administrative steps. British Gas bundles the grant claim into the process, saving you that paperwork.
There are no early repayment penalties on British Gas finance, you can clear the balance at any time without extra fees (British Gas finance terms, 2026). This flexibility means you could take the 0% 24-month option and repay early if your circumstances change, without incurring additional costs.
