The Warm Homes Plan commits £13.2 billion over the parliament to upgrade UK homes with solar PV, batteries, insulation and low-carbon heating. Eligible households can receive a package of grants worth up to £30,000 per home, with low-income and fuel-poor homes prioritised.
- Up to £30,000 in combined grants and 0% loans through the Warm Homes Plan
- Solar, battery, insulation and heat pump upgrades funded for qualifying households
- solar and battery installs until March 2027 (saves ~£2,300 on a 4kW system)
- Get paid for exported electricity through the Smart Export Guarantee (SEG)
