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

To ask the Secretary of State for Business, Energy and Industrial Strategy, if she will make an estimate of the proportion of customers on fixed term energy contracts who entered those contracts before April 2022.

The Department does not collect this information. Ofgem, the independent industry regulator, publishes information about the number of domestic gas and electricity customers with fixed term energy contracts with each supplier: ofgem.gov.uk/energy-data-and-research/data-portal/retail-market-indicators.
