Households across the United Kingdom can reduce their energy costs through a new government-backed Warm Homes Loan Scheme covering technologies such as heat pumps, batteries and solar panels, according to the government factsheet. The scheme, detailed in the government publication, offers no- and low-interest loans that let households install clean energy technology without an upfront payment and instead spread the cost over many years.
The government reported strong demand for these technologies, citing almost 150,000 solar panel installations in the first six months of this year and a record high for heat pump sales in 2025. It said the loans are intended to help thousands more households lower their bills quickly.
According to the factsheet, installing a heat pump, battery and solar panels could help families save up to 550 pounds a year on energy bills, with a further 300 pounds a year possible under a time-of-use tariff. The loans are available to households in England, Scotland, Wales and Northern Ireland.
The government said it worked with lenders to deliver a reduction of up to 5 per cent in interest rates compared with regular loans from banks or high street lenders. As an illustration, the factsheet said a homeowner borrowing 10,000 pounds at 8 per cent over seven years could expect to repay around 155 pounds a month under a loan available at present, while the scheme could save up to 285 pounds a year on repayments.
Ten lenders are initially offering loans, some interest free, with repayment periods of up to thirty years in some cases. The lenders listed are Homeserve, partnering with E.On; HTG Finance; Propensio; Secure Trust Bank; Selina Finance; South Manchester Credit Union; Sunsave; Tandem Bank, partnering with British Gas; The Money Co-op; and This Bank.
Homeowners can also combine a loan with a grant of up to 9,000 pounds through the government Boiler Upgrade Scheme, or Home Energy Scotland in Scotland, further reducing the cost of installing a heat pump. The government described this as the first part of the scheme’s offer, with further lenders and products expected to join as it develops.
The maximum loan supported for each technology is 15,000 pounds for solar panels, 15,000 pounds for an electrical storage battery, 20,000 pounds for an air-water source heat pump, 10,000 pounds for an air-air source heat pump when MCS certification is available, 35,000 pounds for a ground source heat pump, 20,000 pounds for a biomass boiler, 7,500 pounds for a heat network connection and 20,000 pounds for a micro-renewable system.
All installations other than heat network connections will be carried out by MCS-certified installers, which the government said gives consumers confidence that recognised technical and consumer-protection standards will be met.
Energy Secretary Miatta Fahnbulleh said energy is an everyday essential that must be affordable for everyone, and that the government-supported loans would help families across the UK upgrade their homes with no upfront costs so they are warmer and cheaper to run.
Industry figures commented on the scheme. The Green Finance Institute said it co-chaired the partnership that designed and coordinated the launch of the first tranche of loans, and that finance should not block progress. The Money Co-op described participation as a natural fit with its credit union values. Hometree Finance said affordable finance turns home energy upgrades from a significant upfront cost into an achievable investment. HomeServe Finance said responsible finance helps customers overcome upfront costs. Secure Trust Bank Group said it can help households spread the cost at a lower interest rate. South Manchester Credit Union said autumn is a suitable time to launch the scheme as energy prices keep rising. Selina Finance said the upfront cost can be a significant barrier for homeowners. This Bank said it can help homeowners spread the cost of energy-saving upgrades. Tandem said it has funded almost 1 billion pounds of energy efficiency improvements to date. Sunsave said the scheme tackles the cost of borrowing directly. Lloyds Banking Group said it wants to help customers make changes affordably. E.ON UK said the announcement is a step toward removing barriers to low-carbon technologies. British Gas welcomed the move and said its engineers already install more low-carbon heating technology than anyone else in the UK. Good Energy said finance gives households another route to installing solar.
The factsheet also cited household examples. Beth in Birmingham installed 14 solar panels and a battery generating 4,800 kWh annually, with projected savings of 1,050 pounds a year. Tony installed 18 solar panels and a battery, with gross monthly energy bill savings of 191 pounds. David in Bristol installed an air source heat pump, a 7.5 kWh solar array and a battery in 2025, with projected annual generation of 7,034 kWh and projected yearly savings of 1,694 pounds. Stuart installed 24 solar panels and an 11.52 kWh battery in February of this year and estimated first-year savings after costs of around 400 to 500 pounds.
