Money Saving Expert Martin Lewis has issued a warning to anyone who uses direct debit to pay for their heating bills.
The self-proclaimed finance guru says people need to make sure they don't make a costly mistake in an attempt to lower how much they pay every month.
On Tuesday, he took to Twitter to issue a warning, in what appears to be a response to a large number of people asking the same question.

He said: "WARNING! Many talking about cancelling energy Direct Debits to 'keep in control' and just pay when billed.
"Yet be aware that's usually charged at a HIGHER RATE. Price cap (for someone with typical use) paying by:
"Monthly DD £1,971.
"Prepay meter £2,017.
"Quarterly bills £2,100"
On Monday, Martin appeared on Good Morning Britain, where he told co-host Susanna Reid: "We are in the worst position I have seen since I started being the Money Saving Expert back in 2000."
His advice is, as it has been for some time, that for most people the best thing to do to pay as little as you possibly can is to "do nothing" and stick with your current provider."
