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

To ask Her Majesty's Government what is their target for the number of energy efficiency upgrades of UK domestic properties in each of the next three years; and how achievement of those targets will be measured.

We estimate that over 1.2 million energy efficiency measures will be installed in the homes of low income and vulnerable people in Great Britain from December 2018 to March 2022 under the current iteration of the Energy Company Obligation, ECO3. There is no target for the number of installations or properties treated, rather the target is set in notional lifetime bill savings. Further information can be found in the impact assessment online, but also attached.

As a result of the Private Rented Sector Minimum Energy Efficiency Standard we estimate that nearly 900,000 measures will be installed in EPC rated F&G properties in 2020.
