A warning was issued to customers of three energy companies as prices have soared.
People who are with British Gas, Octopus Energy and Shell Energy said their direct debits have doubled since the price rise. This is despite the price cap being half that, according to Money Saving Expert (MSE).
Founded by Martin Lewis, the website said at least 30% of customers with those companies who were in credit and on a price-capped tariff, reported their direct debits increasing. Across all companies, 25% of customers in this situation said their direct debits had doubled or more.
