Great British Insulation Scheme
Under the Great British Insulation Scheme, you could get free or heavily subsidised loft, cavity wall or solid wall insulation to help cut your energy bills. Envirofit makes it simple, we check your eligibility and manage the whole process for you.
What is the GBIS?
The Great British Insulation Scheme is part of the government’s wider plan to reduce energy waste and improve the UK’s housing stock. It focuses specifically on installing insulation in homes that need it most — whether that’s cavity wall insulation, loft insulation or other common upgrades that help keep heat in.
Unlike the ECO4 Scheme, which is aimed mainly at lower-income households receiving benefits, the GBIS also includes a general group, meaning more people are likely to qualify — including those who may not have been eligible for ECO4.
What’s Included?
The GBIS offers a range of insulation measures that can make a big difference to your comfort and energy use. These can include:
- Cavity wall insulation
- Loft insulation
- Solid wall insulation (in some cases)
- Flat roof or pitched roof insulation
- Room-in-roof insulation
Each of these improvements helps to prevent heat from escaping, making your home warmer and more efficient to run.
Why Should You Apply?
1. Save Money on Energy Bills
Insulation is one of the most effective ways to reduce heat loss in your home. The less heat you lose, the less you need to spend keeping your home warm.
2. Make Your Home Warmer and Cosier
Cold spots and draughts can make your home feel uncomfortable, especially in winter. With proper insulation, you’ll notice a real difference in temperature and comfort.
3. Lower Your Carbon Footprint
Better insulation means you’ll use less energy to heat your home — which is great for the planet and supports the UK’s goal of reaching net zero.
4. Support Available for More Households
Even if you don’t claim benefits, you might still qualify for help under the general group. This makes the GBIS one of the most accessible energy efficiency schemes available today.
Do You Qualify?
You could be eligible if:
- Your property has an EPC rating of D to G
- You are a homeowner or a private tenant
- You fall under either the low income or general eligibility group
Not sure what group you fall into? We’re here to help. And if you’re not eligible for GBIS, there’s still a chance you could qualify for the ECO4 Scheme, which includes a wider range of improvements such as heating upgrades and solar panels.
