Martin Lewis has shared some money saving advice for those on certain energy prepayment meters before the July 1 energy price change - and it is the opposite to what he has said before.
The MoneySavingExpert.com founder spoke on his BBC Five Live podcast yesterday to explain how energy prices are likely going drop in July.
He told his listeners that Ofgem had confirmed it will drop - but the exact amount it will drop by won't be revealed until next Thursday (May 25).
Martin explained that from July, the unit price for gas and electricity is most likely going to drop below the Government's Energy Price Guarantee.
Cornwall Insight is predicting the July price cap will fall to £2,053 a year for typical use, meaning a household paying by direct debit will see their energy bills drop by almost £500 a year.
This will be the first time this has happened since October last year when the Energy Price Guarantee was introduced.
In regard to this drop, Martin later answered a question from a fan who asked: "Should you top up your meter or should you put the money in the bank?"
Martin told the caller he was "pretty sure" prices were coming down in July.
He said: "On gas, the meters work so that it is the price when you use the gas that counts so it doesn't matter if you put the money in beforehand."
"On a smart electricity meter, it's the same, you tend to be charged when you use it."
However, the MoneySavingExpert then noted there was one type of meter that doesn't follow this and it would be better to start using up the credit rather than topping up.
He explained: "On a non-smart electricity prepayment meter, you actually want to run down your credit before July, not top it up unless you're absolutely sure you're gonna use it before July 1, and then on July 1, you'll want to go and top up your non-smart electricity meter.
"Because then it's the act of topping up that changes you to the new prices.
"From July onwards, you'll be charged the cheaper rate, so this is the opposite to what I was saying when prices were going up, when I was saying 'pre-load'.
"Now I'm saying 'de-load' if that's a term. But it will only tend to work on non-smart electricity meters."
Martin told his listeners that he would be doing some "I dotting and T crossing" on this subject in the lead up to the price change in July.
