Research claims just one in 10 homes gets the full benefit of loft insulation

Homeowners are disabling the effectiveness of their loft insulation to a massive extent, according to survey data released at Ecobuild.

Research conducted for the company LoftZone found that while some 14.1m of the UK鈥檚 23.3m homes had loft insulation, just 2.6m of those properties benefitted properly from the measure.

The company said a survey of 6,000 people found that 82% used their loft for storage and that 65% had fully or partially boarded the space - reducing the effectiveness of the insulation.

Dave Raval, head of the entrepreneurs fast-track at the Carbon Trust, said the research highlighted 鈥減racticality issues鈥� with insulating UK homes.

鈥淟ofts should be insulated to the recommended 270mm, but homeowners also need the loft for storage,鈥� he said.

鈥淭o board-out a loft, the insulation is reduced to the height of the joists, which is either 75mm or 100mm, or the insulation is compressed below 270mm by placing items on it - both of these reduce thermal capabilities of the insulation and undermine its effectiveness.

鈥淎nother issue is that insulating to 270mm covers the joists, making loft access quite dangerous because it is hard to see where to walk.

鈥淥ften, insulation will be moved to allow access for storage and for maintenance, and it is rarely replaced, further exacerbating the situation.鈥�
