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

The Warm Home Loans scheme became available to UK households on Tuesday, providing borrowing options ranging from £7,500 to £35,000 to finance energy efficiency improvements. Participating energy suppliers including British Gas and E.On have partnered with lenders such as Tandem Bank and Homeserve to deliver discounted loan rates directly to customers, making these technologies more accessible without requiring substantial upfront capital from homeowners.

The financing can be applied toward several green energy technologies. Households installing air-source heat pumps may access loans up to £10,000, while ground-source heat pump installations qualify for up to £35,000 in financing. According to government projections, combining a heat pump installation with battery storage and solar panels could reduce annual energy expenses by approximately £550, with potential additional savings of £300 per year when paired with time-of-use energy tariffs that charge lower rates during off-peak hours.

Energy Secretary Miatta Fahnbulleh characterized the initiative as a means to make home heating and energy more affordable across the country. Officials anticipate the scheme will enable thousands of additional households to transition to low-carbon technologies by allowing customers to distribute repayment obligations across extended periods. A trial conducted in Coventry demonstrated that lower-income households achieved average annual savings exceeding £250 by combining home batteries with time-of-use tariff arrangements.

The loan program launch precedes budget announcements expected later in the week. Government sources indicate potential reductions to existing heat pump grant programs, with Treasury officials viewing current subsidies as primarily benefiting middle-income households. However, grants of up to £9,000 annually are anticipated to remain available for properties not connected to gas infrastructure that depend on heating oil. These grants may be combined with the new low-interest loans 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.
