What is the Free Insulation Grant under ECO4 and GBIS?
The free insulation grant is a government-funded scheme to help homeowners and private tenants improve the insulation on their property.
Under ECO4 and GBIS, government grants for insulation completely fund installation costs, allowing the household to upgrade for zero upfront cost. These improvements can save you £630-£730 per year on energy costs and significantly reduce your home’s carbon emissions.
Types of Home Insulation Grants Available
We offer assistance in securing a range of house insulation grants to suit your specific requirements:
Free Insulation Grant
Available for eligible homeowners, this grant covers the full cost of insulating your home.
Under Floor Insulation Grant
Specifically for under floor insulation, this grant helps prevent heat loss through your flooring.
Internal Wall Insulation Grant
Ideal for insulating internal walls to keep your home warm.
Free Loft Insulation Grants
Targeted at insulating your loft to prevent heat from escaping through the roof.
External Wall Insulation
For homeowners in Scotland, this grant covers the cost of insulating external walls.
Cavity Wall Insulation
For homes built 30 years ago, includes cavity space inside walls which uses same-sized bricks.
How Does Home Insulation Work?
The working principle of home insulation is to trap the heat inside of your home and prevent the outside cool to enter in home. It’s like putting a thermal blanket that wraps your house, a barrier that prevents heat from easily passing through, so there is no constant need for heat.
Most of the insulation materials, such as fibreglass, foam, and wool, trap small pockets of air that hinder heat loss through the walls, roofs, and floors of a house
What Does the Free Insulation Scheme Cover?
Upon approval for the ECO4 or GBIS grant, your home could receive:
Free Loft Insulation Grants
Up to 25% of household heat loss occurs through the roof. Loft insulation keeps your home warmer for longer by preventing heat leakage.
Free Cavity Wall Insulation Grants
In homes with poor wall insulation, a cavity fill reduces heat loss by creating an insulating barrier between the outer and inner walls.
Free Solid Wall Insulation Grants
In older homes with solid walls, up to 45% of heat can escape. Applying internal or external insulation adds a protective layer, reducing heat loss and improving energy efficiency.
Free Underfloor Insulation Grants
Ground-level rooms benefit from underfloor insulation, which blocks drafts from entering, further enhancing the thermal efficiency of the property.
Free Insulation Accounts for 55% of All ECO Installations
The ECO4 initiative takes a whole-house approach to energy efficiency, with insulation being the most popular measure. Over 55% of installations include cavity wall, loft, and solid wall insulation. These energy-saving measures ensure that homeowners get the best solutions tailored to fit their property’s needs, providing maximum efficiency and comfort.
Free Cavity Wall Insulation Leads as the Most Popular Measure
Cavity wall insulation has become the most popular measure under the GBIS scheme, making up 61% of installations. This solution reduces heat loss by filling gaps between exterior and interior walls.
Winter
Keeps the warmth in, preventing heat from escaping through walls.
Summer
Blocks excessive heat, keeping your home cool

Over 3,000 UK Homes Improved by GBIS Since 2023
Since its launch in March 2023, GBIS has been transforming the energy performance of homes across the UK. It installed close to 3,500 energy-saving measures in almost 3,000 households by December 2023, significantly improving comfort and energy efficiency.
Improve Your EPC Rating with Free Insulation Grants
Your property’s energy efficiency is rated by the EPC. Improving your insulation with either an ECO4 or GBIS grant can increase your property’s Energy Efficiency Performance Certificate rating, thus pushing it up to category C and above from categories E, F, and G.
Better insulation will also mean your home meets the standards of modern energy efficiency, as less energy is required to heat or cool a property. This may make your home cheaper to run and more appealing to potential buyers.
Benefits of Free Insulation Grant
Determine if you qualify for any free insulation grants or specific regional grants like insulation grants Wales or free insulation Scotland.
- Lower Energy Bills: Insulation cuts heat losses up to 65%, slashing your annual bills, in some cases, by as high as £630-£730.
- Reduced Carbon Emission: Proper insulation is believed to reduce the carbon footprint produced from a home by as large as 1.7 tonnes per year.
- Increased Value of Property: Houses that are well insulated increase the rating of the Energy Performance Certificate; hence, such a house may always be attractive to buyers.
- Healthier Living Environment: Insulation prevents dampness and mold from building up in your house, improves indoor air quality, and protects your health.
- Comfort All Year Round: Insulation helps maintain stable indoor temperature levels, keeping them warm during winters and cool during summers.
How Much Can You Save with a Free Home Insulation Grant?
In a solid-wall house that is uninsulated, heat losses are recorded as high as 25% through the roof and as high as 45% through the walls. With different types of insulation in wall, floor, and loft installation, homes could reduce up to a maximum of £730 every year on energy bills and save up to 1.7 tonnes of carbon emissions per year

Glass Mineral Wool Insulation
The glass material is recycled, providing several benefits in thermal and acoustic insulation.
Foam Board Insulation
High-insulation polystyrene or polyurethane boards are great for walls and roofs.
Spray Foam Insulation
This type of insulation expands into foam. It thus works best when filling in gaps and sealing around cracks.
Cellulose Insulation
It is eco-friendly because it uses recycled paper. It can be installed in both walls and attics.
