Warm Homes Loan Scheme 2026: what Sussex homeowners need to know
The Government has announced new low- and no-interest loan options for eligible solar panels, batteries and heat pumps.

The Government announced the Warm Homes Loan Scheme on 27 October 2026. It is designed to help households spread the cost of eligible technologies such as solar panels, home batteries and heat pumps, instead of paying the full installation cost upfront.
For homeowners in Worthing and across West Sussex, the scheme could make renewable energy improvements more accessible. However, loan terms and eligibility depend on the participating lender, so it is important to compare the total amount repayable, not just the monthly instalment.
How does the Warm Homes Loan Scheme work?
The finance is provided by participating lenders, not directly by the Government. Some products may be interest-free, while others offer reduced interest rates. The Government says repayment periods of up to 30 years are available in some cases; that does not mean every applicant or technology will qualify for such a term.
Applications remain subject to the lender's normal credit, affordability and eligibility checks. Some lenders work with particular installation companies, while others may allow customers to choose any eligible MCS-certified installer.
How much can you borrow?
The Government has published the following maximum supported loan amounts for individual technologies:
| Technology | Maximum supported amount |
|---|---|
| Solar PV panels | £15,000 |
| Electrical battery storage | £15,000 |
| Air-to-water source heat pump | £20,000 |
| Air-to-air source heat pump* | £10,000 |
| Ground source heat pump | £35,000 |
| Biomass boiler | £20,000 |
*The Government says the air-to-air heat pump option is subject to MCS certification becoming available. These are scheme caps, not guaranteed loan offers. The full list of eligible technologies is in the official Government factsheet.
Why solar panels and battery storage may be worth considering
Solar panels generate electricity during daylight hours. A suitably designed battery can store some surplus generation for later use, reducing the need to buy electricity from the grid in the evening. Certain systems can also charge from the grid during cheaper tariff periods.
But battery capacity should be matched to actual electricity use, tariff arrangements and the existing solar installation. A larger system is not automatically a better investment. An assessment of the property and its energy demand should come before equipment selection.
What savings does the Government suggest?
The Government says a household installing a heat pump, solar panels and a battery could save up to £550 per year on energy bills, potentially rising by a further £300 per year with a suitable time-of-use tariff.
Can you combine a loan with a heat pump grant?
Potentially, yes. The Government says loans may be combined with qualifying support such as the Boiler Upgrade Scheme, with grants of up to £9,000 in relevant cases. However, the same improvement cannot be paid for twice using different government funding schemes. Check current grant eligibility before agreeing to finance.
Do installations need MCS certification?
Yes. According to the Government, installations funded under the scheme must be completed by MCS-certified installers, except heat network connections. Check that the installer holds the appropriate certification for the particular technology and that your chosen lender accepts them.
What should homeowners check before applying?
- Compare lenders: Interest rates, fees, repayment terms and total borrowing costs may differ.
- Check installer choice: Some finance offers are tied to particular installers.
- Get a suitable design: Consider shading, roof suitability, electricity consumption and realistic battery capacity.
- Ask about existing equipment: Some properties may be able to add battery storage to an existing solar installation.
- Review grants: A grant may be more suitable than a loan for eligible households.
- Keep the paperwork: Retain quotes, finance agreements, invoices and installation certification.
