Warm Homes Loan Scheme Lenders: First 10 Named

The Warm Homes Loan Scheme lenders are now named. When the Government launched the scheme on 26–27 October 2026, it published the first ten lenders offering no- and low-interest loans for solar panels, home batteries and heat pumps: HomeServe (partnering with E.ON), HTG Finance, Propensio, Secure Trust Bank, Selina Finance, South Manchester Credit Union, Sunsave, Tandem Bank, The Money Co-op and thisbank. Our Warm Homes Loan Scheme explainer covers the rules; this page is about who you can actually borrow from and what to compare.

The first 10 Warm Homes Loan Scheme lenders

According to DESNZ's announcement as reported by Construction Magazine and The Intermediary, the launch lenders are:

• HomeServe, partnering with E.ON
• HTG Finance
• Propensio
• Secure Trust Bank
• Selina Finance
• South Manchester Credit Union
• Sunsave
• Tandem Bank
• The Money Co-op
• thisbank

DESNZ says more lenders and products will join later. The next lender application window is due to open in late 2026, with onboarding in early 2027, so the list will grow. If your own bank is not on it, that does not mean it will not be.

What the scheme does to your interest rate

Lenders set their own rates and run normal affordability and credit checks, and there is no income threshold. The Government pays each lender a non-repayable grant of up to 20% of the loan, which is passed on as a rate cut of up to 5 percentage points, never below 0%. The grant only applies to loans of three years or more and is paid after the installation has been verified under MCS. Some lenders offer terms of up to 30 years.

DESNZ's worked example is a £10,000 loan over seven years: at 8% it costs about £155 a month, and the scheme could save up to £285 a year. That is a Government illustration, not a quote. Money Saving Expert notes that a 0% rate does not guarantee the cheapest borrowing, and that exact lender rates and fees are not yet published.

Maximum loan by technology

Air-to-air heat pumps (£10,000 cap) cannot be financed yet because MCS standards for them are not in place. Heat pump caps apply before any Boiler Upgrade Scheme grant of up to £9,000, and the two can be combined. Insulation, windows, doors and roofing are excluded.

How to choose between lenders

Installer rules differ. Every installation except a heat network connection must use an MCS-certified product fitted by an MCS-certified installer. Some lenders only work with their own partner installers; others accept any MCS-certified firm. If you already have a quote you like, check that first. Our MCS certificate guide explains why it matters.

Compare the full cost, not the headline rate. Ask each lender for the APR, any arrangement fee, the term and the total repayable. MSE gives about 5.9% APR as the cheapest mainstream personal loan for £7,500 or more, which is the benchmark to beat.

Know what is bundled. Sunsave, for example, is also an installer, so its loan may be tied to its own installation. Our Sunsave battery review covers that side, and interest-free solar panel finance compares the alternatives.

Who can borrow, and where

The loans are open to owner-occupiers and private rented sector landlords across England, Scotland, Wales and Northern Ireland. Landlords with several properties can take a loan for each one. Funding comes from a single central pot, allocated first come, first served, and DESNZ has promised lenders six months' notice when around six months of funding remains.

What to do now

Do not sign anything yet if a rate is not in writing. Get at least two MCS-certified quotes using our home battery installation guide as a checklist, then ask each scheme lender for its rate and total cost on that quote. Compare the result with a standard personal loan and with paying cash. Energy Secretary Miatta Fahnbulleh said the loans "will help families across the UK upgrade their homes with no upfront costs", but affordability checks still apply, so ask each lender whether its loan is secured against your home before you apply.
