Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of trends in demand for insulation retrofitting over the last 20 years; and whether he is taking steps to promote greater stability in the market for insulation retrofitting.

The market for insulation for retrofitting homes has been driven largely by government-initiated schemes. The main ones have been the Energy Company Obligation (ECO, 2013-present); the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP, 2008-2013); and the Energy Efficiency Commitment (EEC, 2002-2008). The number of insulation measures installed over this time can be obtained from https://www.gov.uk/government/collections/household-energy-efficiency-national-statistics.

Going forward the Warm Homes Plan will set out the plans to upgrade up to 5 million homes across the country by accelerating the installation of efficient new technologies. As the first step, the government has committed an initial £3.4 billion over the next 3 years towards heat decarbonisation and household energy efficiency.
