Insulation
More than 40% of all the heat lost in an average home is through the loft space and walls - approximately 33% in an un-insulated home. 250-270 mm of loft insulation can save 25% of a home’s heating costs. Cavity wall insulation is one of the most cost-effective energy efficiency measures in the home. It can save up to £170 each year on a typical home’s fuel bill.
