Millions of homes have an insulation age of 1976 or older – costing households up to £930 a year if they don’t make changes soon, according to a study.
Experts analysing 21 million homes across England and Wales found over half (58%) only meet insulation standards of 1976 or earlier.
As a result, they lose more heat through wall cavity insulation, double glazing, loft insulation, and floor insulation than modern regulations insist on today.
