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

To ask the Secretary of State for Business, Energy and Industrial Strategy, with reference to the Committee on Climate Change's report of June 2018, Reducing UK emissions: 2018 Progress Report to Parliament, if he will make an assessment of the accuracy of the finding on page 95 of that report that home insulation rates are five per cent of peak market delivery in 2012.

As stated in the Committee on Climate Change’s report, the level of home insulation under the Energy Company Obligation (ECO) in 2017 was 5% of the level of home insulation under the Carbon Emissions Reduction Target (CERT) in 2012.

Installations under CERT were at their highest in 2012 as suppliers delivered a significant proportion of their obligation in its final year. Government has reduced the overall level of ECO funding by approximately half since 2012 to reduce the cost burden on domestic energy bills. This funding reduction does not account for a reduction in insulation rates of 95%, where a decreasing potential for easy, low-cost insulation measures is a large contributor to fewer annual installations.
