Claim Your Free Internal Wall Insulation Grant
Many UK homes with solid walls lose up to 45% of their heat through the walls. Internal Wall Insulation (IWI) is a cost-effective solution that dramatically improves energy efficiency by insulating the inside of external walls.
Exploring the Benefits of Free Insulation
Thanks to government initiatives like the ECO4 Scheme, homeowners and tenants across the UK can now access free Internal Wall Insulation, helping reduce energy waste and cut heating bills.
Up to 45% Heat Loss Reduction
Solid walls can leak a huge amount of heat. With IWI, we line the inside of your external walls with insulating boards, keeping the warmth in and the cold out.
Lower Energy Bills & Monthly Savings
By improving your home’s thermal performance, you’ll use less heating. That means noticeable savings on your monthly energy bills.
Increased Comfort & Home Value
Insulation not only makes your home more comfortable all year round but can also increase your property’s energy rating and overall value.
