Solid Wall Insulation (IWI)
ECO3 SCHEME
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
