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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the number of energy suppliers that have ceased trading in each of the last two years; what estimate he has made of the number of consumers that have been transferred to alternative energy suppliers as a result; and what estimate he has made of the total additional estimated cost to consumers of those transfers.

Information on energy suppliers that have ceased trading, and their customer base, is published by the regulator Ofgem at https://www.ofgem.gov.uk/publications/check-whos-taken-over-your-energy-supply.

Suppliers can make a claim for the unrecoverable costs of acting as the supplier of last resort. The individual claims and decisions can be found on Ofgem’s website.
