Most homes built from 1920 onwards have cavity walls

British households spent £500m on heating last year, only to see it disappear through poorly insulated walls and roofs.

According to data from the Departmant of Energy and Climate Change (DECC), the heat escaped from homes with less than the recommended depth of loft insulation (270mm) or uninsulated cavity walls.

Energy saving measures

Loft and wall cavity insulation can be professionally installed for a combined total of £500 and could save £160 off a household's annual heating bills, according to DECC.

In addition to the financial savings, DECC says insulation can add value to your home and improves the home energy rating provided in a HIP. The energy saved would also help move the UK towards hitting its target of an 80% cut in carbon emissions by 2050.
