Free Internal Wall Insulation Grant
What is Internal Wall Insulation?
Internal wall insulation is a highly effective way to reduce heat loss through solid walls by adding insulation boards or stud wall systems to the inside of your home. It’s ideal for properties with solid walls (common in pre-1920s buildings) that cannot benefit from cavity wall insulation.
Through the ECO4 and GBIS government schemes, eligible homeowners may qualify for a free internal wall insulation grant. This upgrade can drastically improve your home’s energy efficiency, reduce heating bills, and increase comfort all year round.
Internal insulation grants are designed to help homeowners with poor EPC ratings and high heating costs. If you’re eligible, installation is completely free under the scheme.

How Internal Wall Insulation Works?
Internal wall insulation is designed for homes with solid external walls, where cavity wall insulation isn’t an option. The process involves attaching rigid insulation boards or a stud framework filled with insulation material to the inside of your external walls. A new plaster finish is then applied to complete the installation.
This method creates a thermal barrier that reduces heat loss, making your home significantly warmer in winter and more energy efficient year-round.
Thanks to the internal insulation grants available under the ECO4 and GBIS schemes, eligible homeowners can have this work carried out completely free of charge.

Why Choose Internal Wall Insulation?
Internal wall insulation is a smart solution for improving the energy efficiency of homes with solid walls. If your home was built before 1920 and lacks cavity walls, this upgrade helps lock in heat, reduce fuel costs, and create a more comfortable living space.
Cut Heating Costs
Stop heat escaping through uninsulated walls and reduce your winter energy bills significantly.
Boost Indoor Comfort
Enjoy consistent room temperatures and fewer draughts — no more cold patches near external walls.
Lower Your Carbon Footprint
Insulating solid walls reduces energy consumption, helping you contribute to a greener environment.
