Martin Lewis has issued a warning to anyone who pays their energy bills by direct debit ahead of new higher costs coming in this weekend.
From Saturday (October 1), dual-fuel customers on a standard variable tariff who pay by direct debit will be charged a maximum of 10p per kWh of gas and 34p per kWh of electricity. This is a jump from 7p and 28p for gas and electricity respectively of what people are paying at the moment.
With less than a day to go before the hike, Mr Lewis has reissued a warning on social media.

The Money Saving Expert founder took to Twitter on Thursday to alert people. He said: "WARNING: It's #MeterReadingWeek. On Sat most energy bills rise 27%". He also shared a video that explains what people should do ahead of the price rise.
In the clip, Mr Lewis said: "If you pay by direct debit, firms estimate your use and they also estimate when it's used, so you don't want them to assign more of your units to the more expensive period.
"How do you stop that? You submit a meter reading. Take a picture, too, so you have evidence. That way, there's no estimate and there's no discrepancy.
"Those with working smart or pre-pay meters, you don't need to bother, but you [still] might want to take a picture of where you're at on the day."
However, Mr Lewis also shared a tip that could benefit some on pre-pay meters. He continued: "If you've got cash now, and I know many people don't have cash, but if you do... topping up in September, you could then keep that rate into October and beyond, when the prices rise".
He said you'll keep that rate until you top up again, though it doesn't work with gas, or if you're on a smart meter. Mr Lewis added: "If you're on a pre-pay meter with E.ON or Scottish Power they have told me it won't work. But all the rest of the big firms, they've said it is likely".
