The ECO4 scheme is a UK government programme running until March 2026 that provides free or heavily subsidised energy efficiency improvements to eligible households, funded by major energy suppliers.

ECO4 grants range from £800 for loft insulation up to £10,000 for ground source heat pumps, with most households receiving £2,000-£5,000 worth of improvements.
