London launches interest-free loans for solar panels and heat pumps

--- The context --- The British government has launched the Warm Homes Loan Scheme, government-backed no- and low-interest loans to install heat pumps, batteries and solar panels with no upfront cost. Demand is soaring, with almost 150,000 solar panel installations in the first six months of this year and heat pump sales at a record high in 2025. --- The facts --- Installing a heat pump, battery and solar panels could save up to £550 a year on energy bills, rising by a further £300 a year with a time-of-use tariff. The loans are available across the entire UK, in England, Scotland, Wales and Northern Ireland, with an up-to-5 per cent reduction in interest rates from regular loans. As an example, borrowing £10,000, at 8%, over seven years would mean repaying around £155 a month with a loan available right now, while through the scheme the same homeowner could save up to £285 a year on repayments, alongside ten lenders initially offering loans, some interest free, with up to thirty years to repay in some cases. Homeowners can also combine a loan with a grant of up to £9,000 through the Boiler Upgrade Scheme, further reducing the cost of installing a heat pump. --- The positions --- Energy Secretary Miatta Fahnbulleh said in reported terms that energy must be affordable for everyone, and argued that these loans will help families upgrade their homes with no upfront costs, making them warmer and cheaper to run. --- What remains unknown --- The maximum loan for each technology is set clearly: solar panels up to £15,000, an electrical storage battery up to £15,000, an air-water heat pump up to £20,000, an air-air heat pump up to £10,000, a ground source heat pump up to £35,000, a biomass boiler up to £20,000, a heat network connection up to £7,500 and a micro-renewable system up to £20,000. All installations, except for heat network connections, will be carried out by MCS-certified installers, meeting recognised technical and consumer-protection standards. --- Unanswered questions --- How many households will take up the scheme in its first stage? Will the savings outweigh monthly repayments for homes with lower energy use? Will new lenders join to widen competition? --- EPM analysis --- The design replaces the upfront cost with payments spread over years, combining cheaper credit and a direct grant. 📌 EPM Take: In EPM's view, the strength of the scheme lies in joining interest-free or cheap credit, a combinable grant and certified standards in a single route open across the whole country. If the ten initial lenders truly compete and long terms do not inflate the total cost, thousands of households can cut bills without paying upfront. The real test will be actual take-up and proven savings in each home, not the initial announcement of the British government programme itself.
