Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what information he holds on the number of UK households that have installed (a) additional and (b) replacement loft insulation in each year since 2011-12.

The table below presents the number of loft insulations per year delivered through major Government schemes since April 2011. These include an estimate of the lofts insulated using DIY material provide as part of the Carbon Emissions Reduction Target up to December 2012.
