Solid Wall Insulation in Leeds

Homes built before the 1920s typically have solid walls with no cavity to fill. These properties lose even more heat than cavity wall homes. Solid wall insulation — applied either internally or externally — can dramatically improve comfort and reduce energy bills. While more expensive than cavity insulation, it makes the biggest difference in older properties common across Leeds, Bradford, and the wider West Yorkshire region. External wall insulation (EWI) and internal wall insulation (IWI) are both effective options, and the solid wall insulation cost can be significantly reduced through ECO4 grant funding for eligible households.
