Great British Insulation Scheme
What Is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is a UK Government initiative designed to make homes warmer, more energy-efficient, and cheaper to heat.
It offers funding for insulation upgrades to help households reduce energy waste, cut bills, and support the UK’s journey to net zero.
Under this scheme, energy companies are required to provide free or heavily subsidised insulation to eligible households — ensuring everyone, not just high earners, can benefit from a warmer, more efficient home.
From loft and cavity wall insulation to solid wall upgrades and underfloor insulation, GBIS is a practical and immediate way to improve comfort and save money year after year.
How the Scheme Benefits You
Getting insulation through GBIS doesn’t just make your home feel cozier — it delivers real, lasting benefits:
✅ Lower Energy Bills
Good insulation locks in heat, helping you use less energy to stay warm. Many homes save up to £400 a year on heating costs.
✅ A Warmer, More Comfortable Home
Say goodbye to cold draughts and uneven room temperatures — insulation keeps warmth where it belongs.
✅ Government-Backed Funding
Because this scheme is supported by the UK Government and energy suppliers, you won’t face upfront costs if you qualify.
✅ Boosts Property Value & EPC Rating
Improving your home’s insulation raises your Energy Performance Certificate (EPC) rating, making your property more valuable and attractive to buyers.
✅ Cuts Carbon Emissions
Every bit of insulation helps the UK move closer to its net zero goals, reducing carbon footprints across the country.
What Insulation Improvements Can You Get?
Depending on your home’s construction and current insulation level, the scheme may cover:
Loft insulation – Prevents up to 25% of heat loss through your roof.
Cavity wall insulation – Keeps your home warm by filling gaps between walls.
Solid wall insulation – Ideal for older homes without cavity walls.
Underfloor insulation – Stops heat escaping through floors.
Room-in-roof insulation – Perfect for loft conversions or upper rooms.
All installations are completed by certified retrofit specialists, ensuring professional, long-lasting results.
