Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many of each insulation measure obligated energy suppliers have delivered under the Great British Insulation Scheme since 30 March 2023.

The draft Order establishing the Great British Insulation Scheme in law requires first year measures to be notified to Ofgem, as scheme administrator, by 31 January 2024. Ofgem will then publish information on measures delivered under the Scheme.
