What is the Great British Insulation Scheme (GBIS)
The Great British Insulation Scheme is a government initiative to improve energy efficiency in eligible British homes. The scheme is exclusively for adding or upgrading home insulation with free or discounted installation. It is offered alongside the existing ECO4 scheme that can provide additional home energy efficiency upgrades to eligible low income households.
At the heart of the scheme are affordability and comfort, so if you make your home more energy efficient, it will keep a consistent temperature, making it more cost-effective and cosy. The scheme was launched in the summer of 2023 and will run until March 2026.

There are a variety of different kinds of insulation that can be provided through GBIS:
- Cavity wall insulation
- Internal or external solid wall insulation
- Loft insulation
- Flat or pitched roof insulation
- Underfloor insulation
- Solid floor insulation
- Park home insulation
- Room-in-roof insulation
Installation typically takes 2–7 days, with radiators installed in every room. This funded upgrade not only reduces your heating bills but also ensures a warmer, more comfortable living space for you and your family—completely free of charge!
What's the eligibility criteria for GBIS?
If you meet the following eligibility criteria you could benefit from free cavity wall insulation through the Great British Insulation Scheme:
You’re on qualifying benefits and are a homeowner with an EPC rating of D to G, or you privately rent your home and have an EPC rating of D or E, or you’re a homeowner with an EPC rating of D or lower and a council tax band of A to D in England, or A to E in Wales/Scotland.

If you qualify through our online eligibility checker, we’ll need to perform a no-obligation home survey to make sure we can install insulation.
Am I eligible?
There are two groups who can apply for the Great British Insulation Scheme – a general group and a low-income group. The eligibility criteria for each group differ, so read carefully to see whether you qualify.
General Group
To be eligible for the general group, you must:
- Live in a home in council tax bands A to D (England)
- Live in a home in council tax bands A to E (Scotland) and have an EPC rating of D to G
- Private renters: your EPC must be in band D or E
Low Income Group
To be eligible for the low-income group, you must:
- Receive qualifying benefits (see below)
- Live in the least energy-efficient housing
- Have an EPC rating of D to G
This group will be eligible for lower cost or free insulation and owner occupied households could receive heating controls too.
How does insulation help me save?
The average household spends more than half their energy bill on heating and hot water according to research. Yet, a large amount of that heat simply escapes into the great outdoors through our windows, walls, roofs, and more. Insulating our homes is like wrapping them in a warm cosy blanket. The insulation helps to trap in the heat we are generating so our boiler doesn’t have to work quite so hard to keep us warm. This saves energy and money on heating our home.
Why is insulation important?
Insulating your home and preventing heat loss from your walls and roof is one of the best things you can do to reduce your energy bills, keep your home warm and improve indoor air quality through better ventilation – as well as being much better for the planet.
Insulation can be a large upfront cost which a lot of people can’t afford – which is where the Great British Insulation Scheme comes in.
