Question to the Department for Business, Energy and Industrial Strategy:
To ask the Secretary of State for Business, Energy and Industrial Strategy, if he will make an estimate of the rate of uptake of home insulation improvements in the last five years.
The Department for Business, Energy and Industrial Strategy only holds data on the number of insulation measures installed though central Government Schemes. This includes measures delivered through the Carbon Emission Reduction Target (CERT), Community Energy Saving Programme (CESP), Warm Front, Energy Company Obligation (ECO) and the Green Deal.
Between the start of July 2011 to the end of June 2016 through Government schemes, there have been 1.61 million cavity wall insulation installations, 2.7 million lofts insulated, and 267,000 solid wall insulation installations.
Delivery since April 2013 is reported in Table 4.3 in the latest Household Energy Efficiency National Statistics Release here:
Delivery statistics since April 2008 is available in Table 4.3 here: https://www.gov.uk/government/statistics/household-energy-efficiency-national-statistics-detailed-report-2015
