Solid Wall Insulation (IWI)

Insulating solid walls could cut your heating costs considerably, because they let through twice as much heat as cavity walls

Internal Wall Insulation Grants

Internal wall insulation can dramatically reduce the amount of warmth that escapes from a property thereby reducing energy bills and creating a warmer home.

Properties built prior to 1930 will most likely have solid walls. These typically allow more heat to pass through than a standard cavity wall, but can still be insulated.

Solid walls can be insulated from the inside. Typically this will cost more than insulating a standard cavity wall, but the savings on your heating bills will be bigger too.

Typical installation costs for a solid wall insulation is around £7,400, However this can be done for free under ECO3

*Based on a typical semi-detached house in Great Britain
