Warmer home. Lower bills. Smaller footprint.
That’s what ECO4 is all about. It’s a government scheme (funded by energy suppliers) that helps households cut costs and carbon by upgrading their homes with things like insulation, heating systems, and renewables. If you’re eligible, you could get these improvements for free. ECO4 runs until 2026, so there’s never been a better time to make your home future-proof.
ECO4
GBIS
Keep the heat in. Cut the waste. Pay less.
That’s the Great British Insulation Scheme (GBIS). Launched in 2023, it helps households across the UK reduce energy bills with subsidised insulation upgrades — from lofts and cavity walls to solid walls. Unlike ECO4, GBIS is open to more people, including many middle-income households who wouldn’t usually qualify for full funding. The goal is simple: stop heat escaping, make homes more efficient, and keep energy costs under control.

✅ Funded by the big energy suppliers
✅ Full home upgrades — insulation, heating, renewables
✅ Aimed at low-income and vulnerable households
✅ Work is fully funded
✅ Runs until 2026
