Under the ECO4 scheme, you may be eligible to have a fully funded insulation upgrade at home if it is energy inefficient and subject to certain conditions.
Note: If you're a homeowner and don't have a benefit letter, you can still qualify if your Council Tax Band is A to D in England or A to E in Scotland and Wales.
The Great British Insulation Scheme helps UK households improve their energy efficiency through two major eligibility routes: the Low-Income Group and the General Group.
We make it simple for you. From checking your eligibility to a complete energy upgrade, our government-approved installers handle everything fast and professionally.
Before applying, you should confirm whether you qualify for free Insulation.
If you are not receiving ECO4 qualifying benefits, you are still eligible under the Great British Insulation Scheme.
After approval, TrustMark-registered installers carry out the full retrofit, typically within 2–3 working days.

Are you eligible for installing free insulation at your home?
An insulation grant can keep your home warm, cut energy bills, and reduce greenhouse gas emission. By improving insulation, you prevent heat loss, keeping your home comfortable in winter and cooler in summer. These grants provide support for insulation costs helping you save money annually while also being more energy efficient and eco-friendly.
ECO4 Scheme is the fourth phase of Energy Company Obligation (ECO), which aims to help those families who cannot afford upgrading their home heating and insulation. A key objective of the ECO4 scheme is to improve the Energy Performance Certificate (EPC) ratings of homes. Improving EPC ratings makes homes more energy-efficient, which lowers energy bills and helps protect the environment.
The ECO4 Scheme has made a significant impact in the UK. These installations help families stay warm, reduce home’s energy waste, and cut down on carbon emissions. So far, it has led to the installation of:
Cavity wall insulations
19,152
Solid wall insulation
40,074
Under-floor insulation
1,248
Other insulations
3,224
Loft insulation
63,097
The Great British Insulation Scheme (formerly ECO+) was initiated in late March 2023, and in its first year after the launch, over 11,600 insulation measures had been installed in 9,400 homes. GBIS focuses on improving the energy efficiency of homes that do not qualify for the ECO4 scheme. With a £1 billion budget, this initiative aims to help about 300,000 households across the UK to reduce fuel poverty and lower carbon emissions. Unlike ECO4’s ‘whole-house approach, Great British Insulation Scheme typically provides just one type of insulation per home. It mainly covers loft and cavity wall insulation, which can save households up to £300 annually.
Targets low-income households, people receiving certain benefits, and vulnerable groups.
Available to a broader range of homeowners, including middle-income households.
Prioritises helping those in fuel poverty by fully covering insulation costs.
Provides partial funding, helping more people make homes energy efficient but may require some contribution.
Covers various types of home insulation, including loft, cavity wall, and external & internal walls insulation
Focuses mainly on loft & cavity walls in addition to internal & external wall insulation for quick and effective energy savings.
Offers more extensive home's energy improvements, including heating upgrades alongside insulation
Primarily aims to improve insulation to reduce your energy bills.
Often involves more rigorous assessments and eligibility checks.
Simpler application process, making it accessible to a wider audience.
Two main areas where insulation minimises up to 60% heat loss include loft or attic areas and cavity walls. The grants from the UK government mainly targets these two areas to improve EPC rating of your property.
You can add a new or upgrade old loft insulation through the ECO4 and GBIS grants.
Material: Wool glass and polystyrene
Insulating the cavity between your external walls helps keep heat inside during the winter and prevents heat from entering in the summer.
