”But if you're thinking of ditching your direct debit, I do need to make you aware of something. While you may gain control, it will cost you more.
"Now, the numbers I'm about to give you are for someone on typical usage. Of course, if you use more or if you use less, it changes in rough proportion, but I thought it would help you to just get an idea of the difference.
"If you're on typical usage, the price cap from 1 April – for somebody paying by direct debit – is £1,971 a year. If you pay by prepayment, it's £2,017 a year, but of course you'd need a prepayment meter for that. If you want to pay by quarterly bills, and that's what most people ditching direct debit tell me they're thinking of doing, then the price cap is £2,100. So that means you're paying over 6% more for the same usage than you do by direct debit, because there is a discount allowed for direct debit.
"So while you might have more control in the short term, over the longer period, ditching monthly direct debit means you will pay more for your energy, about 6% more, taking that increase from 54% to well over 60%. I can't tell you what to do, but if you can cope with the direct debit, it is cheaper to do so."
