We're working on the final details of this scheme and we’ll let you know when you can start applying
What is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is designed to be complementary to the current ECO scheme, which is known as ECO4. The scheme will help install energy efficient measures that will lower your energy usage and save you money on bills. The scheme will launch by Summer 2023 and run until March 2026. The government believe the scheme will save households around £310 a year.(1)
How will the Great British Insulation Scheme help lower my bills?
Making our homes more energy efficient is the best way of cutting household energy use and reducing heating bills.
Insulation measures are included in this scheme and will help reduce heat loss and save money on your heating costs. This is because insulation keeps heat from escaping through your loft, windows and walls.

Here are some of the measures we'll offer under The Great British Insulation Scheme

Loft insulation
Did you know that a typical home without insulation can lose 25% of its heat through its roof?
Adding insulation to your loft will help you keep your home warm, wasting less energy and lowering your home's carbon emissions.

Cavity wall insulation
Cavity wall insulation is one of the best and most affordable ways to improve your home's energy efficiency.
Insulating the cavity space between the outside and inside wall adds a barrier to stop the cold from coming in and heat from escaping.
