To ask Her Majesty's Government what estimate they have made of how many dwellings in the UK have received (1) cavity wall, and (2) loft insulation since 2010; and how many applicable homes they estimate remain untreated.

The Department for Business, Energy and Industrial Strategy published statistics provide information on insulation measures that have been delivered through the Government’s energy efficiency schemes.
Between January 2010 and September 2018 (the latest date for when data is available), there have been 2.4 million cavity wall insulation measures and 4.6 million loft insulation measures installed to homes across Great Britain.
We estimate that in Great Britain there are a further 5.3 million homes suitable for cavity wall insulation; of which 4.0 million are considered to be easy to treat; and 8.1 million homes have the potential for additional loft insulation; of which 5.8 million are considered to be easy to treat.
