Almost 850,000 homes had new insulation installed in the twelve months to December 2014 according to the latest figures released by the Department of Energy and Climate Change (DECC).
It is estimated that as of the last month of 2014, there were 27.4 million homes in Great Britain and of these, 19.4m had cavity walls with the remaining 8m having solid walls, and around 24m properties also had a loft.
Compared with December 2013, the number of homes to have cavity wall insulation increased by 460,000 to more than 14m – meaning 73% of those with cavity walls. According to DECC, most of the remaining homes without cavity wall insulation are hard to treat, with only half a million of them being uninsulated easy to treat standard cavities.
Similarly, 70% of homes with lofts have loft insulation of at least 125mm, with only around 1% of the remaining properties thought to have no insulation in place.
It is thought that the increased number of properties with adequate loft insulation could be linked to the number of Green Deal Assessments (GDAs) taking place across Great Britain. In the two years following the Green Deal’s launch in January 2013, DECC’s figures show more than half a million GDAs have taken place, with the most common single measure to be recommended being the installation of loft insulation.
In contrast with the high proportion of insulated cavity wall homes and those with lofts, DECC says only 294,000 solid wall homes had insulation, accounting for just 4% of Great Britain’s solid wall properties.
