Homes across UK to get low- or no-interest loans to fund solar panels and heat pumps

The UK government has introduced the Warm Home Loans scheme, a financing initiative designed to help households upgrade their homes with low-carbon energy technologies. The program, which became available on Tuesday, offers interest-free or discounted-rate loans ranging from £7,500 to £35,000. Participating energy suppliers including British Gas and E.On have partnered with lending institutions such as Tandem Bank and Homeserve to provide these loans directly to customers at reduced rates compared to conventional high street borrowing options.

The loans can be used to fund various home energy improvements. Households looking to replace gas boilers with air-source heat pumps can borrow up to £10,000, while those installing ground-source heat pumps may access loans of up to £35,000. According to government projections, combining these technologies with solar panels and batteries could reduce annual energy bills by up to £550, with additional savings of £300 possible when paired with time-of-use tariffs that charge lower rates during off-peak hours.

The scheme aims to address barriers preventing wider adoption of clean energy technologies among households. Government officials anticipate that thousands more families will be able to afford these upgrades by spreading repayment costs over extended periods rather than paying large sums upfront. Recent trials have demonstrated tangible benefits, with fuel-poor customers in Coventry saving more than £250 annually on average through home battery installation combined with time-of-use pricing structures.

The announcement comes one day before the chancellor’s budget presentation and reflects broader government energy policy considerations. While the boiler upgrade scheme, which currently provides grants of up to £7,500, is expected to see budget reductions, households not connected to the gas grid may continue accessing grants of up to £9,000 annually. These grants can be combined with the new loan program to cover complete installation costs. Additional lenders participating in the scheme include HTG Finance, Propensio, Secure Trust Bank, Selina Finance, South Manchester Credit Union, Sunsave, The Money Co-op, and This Bank.
