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

To ask the Secretary of State for Business, Energy and Industrial Strategy, if he will publish details of the business model his Department used to determine the pre-payment meter energy price cap.

The prepayment safeguard (price cap) tariff was introduced by the Competition and Markets Authority (CMA) following its investigation into the energy markets. The methodology set by the CMA, and administered by Ofgem, to calculate the cap was brought into effect by the CMA’s Energy Market Investigation (Prepayment Charge Restriction) Order 2016, which is available on the CMA’s website here, https://www.gov.uk/government/publications/energy-market-investigation-prepayment-charge-restriction-order-2016
