UK Home Energy Loans: Interest-free schemes launch for solar and heat pumps

The United Kingdom government launched a new lending program on Tuesday to help households finance low-carbon energy upgrades without upfront costs. The Warm Home Loans scheme provides interest-free or low-interest loans to fund the installation of heat pumps, batteries, and solar panels.

The initiative aims to reduce annual energy bills by hundreds of pounds for participating families. Loans under the program range from £7,500 to £35,000. The government states that thousands of additional households will gain access to these technologies through the new funding structure.

Energy suppliers are partnering with specific financial institutions to distribute the loans. British Gas has partnered with Tandem Bank, while E.On works with Homeserve. These partners offer rates lower than those typically available from high street lenders. Other participating lenders include HTG Finance, Propensio, Secure Trust Bank, Selina Finance, South Manchester Credit Union, Sunsave, The Money Co-op, and This Bank.

Households can apply for specific loan amounts based on the technology installed. Air-source heat pumps qualify for loans of up to £10,000, while ground-source models can access up to £35,000. These loans can be combined with existing government grants of up to £9,000 annually for fossil fuel heating replacements. The government estimates that installing a heat pump, battery, and solar panels could save households up to £550 per year. Adding a time-of-use tariff could increase those savings by a further £300 annually.

The scheme launched one day before Chancellor John Healey delivers his first budget on Wednesday. Sources indicate the budget will scale back heat pump grants from the existing boiler upgrade scheme. The five-year budget for those grants is £2.7bn, but hundreds of millions of pounds are expected to be cut. Treasury officials view the current subsidies as benefiting middle-class households primarily. Grants of up to £9,000 are likely to remain available for households not connected to the gas grid.

Energy Secretary Miatta Fahnbulleh stated that energy must be affordable for everyone. She said the government-supported loans will help families upgrade their homes to make them warmer and cheaper to run. Chris Norbury, chief executive of E.On UK, noted that a trial in Coventry showed fuel-poor customers saved over £250 annually by combining a home battery with a time-of-use tariff. He described the new scheme as an opportunity to remove barriers to low-carbon technologies.

Previous grant programs typically provided up to £7,500 toward the £13,600 cost of a heat pump installation. This left households with a substantial outlay to cover the remaining costs. The new loan structure allows borrowers to spread repayments over many years, addressing the initial cost barrier that previously limited adoption.
