Insulation: Housing Greg Clark To ask the Secretary of State for Energy and Climate Change how many and what proportion of homes have (a) no loft insulation, (b) between 0 and 199mm of loft insulation, (c) between 200 and 249mm of loft insulation and (d) 250mm or more of loft insulation. Joan Ruddock The following data has been estimated by combining the 2005 English House Condition Survey data with Ofgem’s data for the number of loft insulations carried out under the Energy Efficiency Commitment 2005-08. For Great Britain, the estimated proportions are as follows: ------------------------------------------------------- |Loft insulation thickness|Percentage of stock in 2008| ------------------------------------------------------- |None |3.60 | ------------------------------------------------------- |less than 50 mm |2.85 | ------------------------------------------------------- |50 mm up to 99 mm |21.76 | ------------------------------------------------------- |100 mm up to 149 mm |34.80 | ------------------------------------------------------- |150 mm up to 199 mm |11.95 | ------------------------------------------------------- |200 mm or more |25.04 | ------------------------------------------------------- |Total |100.00 | ------------------------------------------------------- Around 71 per cent. of homes in Great Britain have between 0 mm and 200 mm of insulation. The English House Conditions Survey and its equivalents in Scotland and Wales do not provide data on the number of homes with insulation depths between 200 mm and 250 mm, or on the number with more than 250 mm. Sarah Teather To ask the Secretary of State for Energy and Climate Change what estimate his Department has made of the financial turnover of the domestic insulation market. Joan Ruddock The insulation sector domestic market size is projected to increase by 32 per cent. by 2012 compared with 2007, reaching £1,109 million in 2012 (at 2007 prices).
