Internal Wall Insulation Grants
What is Internal Wall Insulation?
Internal wall insulation is one of the most effective ways to reduce heat loss in solid wall properties. It involves adding insulation boards or stud wall systems to the inside of your external walls, creating a thermal barrier that keeps warmth in and cold out.
This method is ideal for homes built before the 1920s, where solid brick or stone walls are common and cavity wall insulation isnโt an option.
Thanks to the UK Government’s ECO4 and GBIS schemes, eligible homeowners could have internal wall insulation installed completely free of charge. These grants are designed to support households with poor energy ratings and high heating costs โ helping you stay warm without the expense.

How Internal Wall Insulation Works?
Internal wall insulation is specially designed for homes with solid external walls, where cavity wall insulation isnโt possible. It works by creating a thermal barrier on the inside of your walls to stop heat escaping.
Insulation boards or stud framework are fixed to the inside of your external walls.
The system is filled with high-performance insulation material.
A fresh plaster finish is applied โ ready to decorate as normal.
Once installed, your walls retain heat far more efficiently, helping you stay warmer in winter and reduce heating bills all year round.
Under the ECO4 and GBIS schemes, qualifying homeowners can have internal wall insulation installed completely free of charge โ including materials, labour, and finishing work.
