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

To ask the Secretary of State for Business, Energy and Industrial Strategy, how many homes have been insulated under national government schemes in each year since 2010.

Since 2013, and estimated 1,321,000 unique homes have received insulation measures through the Energy Company Obligation (ECO) and Green Deal schemes. The annual breakdown is shown in the table below.

Table: Number of homes insulated through ECO and Green Deal: 2013 – July 2017.

*Around 15,000 homes (1%) were insulated by multiple schemes since 2013. This double counting has been removed from the total homes insulated.

Prior to 2013, data are not available to estimate the number of unique homes receiving insulation measures. However, the number of professionally installed measures for cavity wall insulation, loft insulation and solid wall insulation through Government schemes since 2010 are shown in the table below. In addition to schemes shown above the Carbon Emissions Reduction Target (CERT) that closed in 2012 is included.
