Warm Homes Loan Options for UK Homeowners
An independent guide to the Government's Warm Homes Loan Scheme, its loan limits, lenders and risks.
Overview
We are an independent guide to the Warm Homes Loan Scheme, a government scheme for home energy upgrades. This page explains what the scheme offers, what is still unconfirmed and how to protect yourself. We use published sources only, and we list them at the end of the page. We are not a lender, and we cannot process applications.
The Government announced the scheme in January 2026 as part of its £15bn Warm Homes Plan. Launch was confirmed on 26 October 2026. Some key details are still unpublished. We will update this page as each detail appears.
Independent guide. We are not a lender or a government body. Always check current scheme rules with the official provider.
How the loans work
The Treasury partly backs each loan. This backing lets lenders offer rates up to 5 percentage points lower than their normal rates. For example, a rate of 8% would fall to 3%. Some borrowers may get a 0% rate. Lenders have not yet published their final rates.
Loan terms start at 3 years and reach 30 years in some cases. Some products are secured loans, such as second mortgages. A secured loan uses your home as security, so read every term with care. Terms over 20 years can carry higher rates and a much higher total cost.
Maximum loan amounts by measure
The scheme sets a maximum loan for each type of upgrade. Each limit is the most you can borrow for that measure. Your actual loan depends on your quote and on the lender's own checks. The table below lists every published maximum.
| Measure | Maximum loan |
|---|---|
| Solar panels | £15,000 |
| Battery storage | £15,000 |
| Air-to-water heat pump | £20,000 |
| Air-to-air heat pump | £10,000 |
| Ground source heat pump | £35,000 |
| Biomass boiler | £20,000 |
| Heat network connection | £7,500 |
| Micro-renewables such as domestic wind | £20,000 |
You can combine the loan with the Boiler Upgrade Scheme grant. That grant covers heat pumps and biomass boilers in England and Wales. A grant lowers the amount you need to borrow, which lowers your total cost of credit.
