British Gas, Octopus Energy and Shell Energy customers claim their direct debits have doubled since the price rise, despite the price cap being half that, according to Money Saving Expert (MSE).
The website, founded by Martin Lewis, said at least 30% of customers with those companies, who were in credit and on a price-capped tariff, reported their direct debits increasing. And across all companies, 25% of customers in this situation said their direct debits had doubled or more.
The results were gathered from a survey carried out by MSE between April 26 2022 and May 3 2022, with 41,000 responses. It added that the survey was self-selecting, so some people may have responded more frequently.
