UK Warm Home Loans offer £7,500 to £35,000 for heat pumps, batteries and solar panels

The UK's Warm Home Loans scheme, launched in October 2026, offers government-backed loans of £7,500 to £35,000 at interest-free or low rates. They fund home upgrades such as heat pumps (systems that heat homes electrically), batteries and solar panels, so households avoid paying the full cost up front.
