Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many homes had energy efficiency measures installed in (a) 2010 and (b) 2022.

The Department estimates that 114,200 homes had measures installed through Government funded schemes in 2022. All measures under the following schemes are included in this total: Energy Company Obligation, Green Homes Grant Vouchers, Green Homes Grant Local Authority Delivery, Homes Upgrade Grant, Renewable Heat Incentive, Boiler Upgrade Scheme, and Social Housing Decarbonisation Fund. This total will include a small amount of double counting of households that received measures through multiple schemes.

Prior to 2013, the Government support for energy efficiency measures was provided via the Carbon Emissions Reduction Target and Community Energy Saving Programme. More information can be found here and here.
