Money Saving Expert founder Martin Lewis has warned customers who pay their energy bills via direct debit about steps they can take to mitigate the rise in costs.
From October 1 people who pay their bills via direct debit will be charged up to 10p per kilowatt hour of gas that they use and 34p per kilowatt hour of electricity.
This is a rise of 3p for gas and 6p for electricity from the previous totals of 7p and 28p for electricity, the Liverpool ECHO reports.
