Martin Lewis issued an apology after his advice on non-smart prepayment meters became "less certain". He had previously advised people with prepayment meters that if they topped up before the April 1 price cap rise, they will be charged at the rate they topped up, until they top up again.
However, he has since revealed this may not be the case. On March 24, he explained on his Money Saving Expert website that after receiving confirmation from "all major firms" expect Scottish Power that the tip would work, he contacted Ofgem to see if Scottish Power were breaking any rules.
Unfortunately, Ofgem reported that there is "nothing in the licence conditions" that prevents firms from ensuring people pay the rates from April 1, no matter when they top up. For Scottish Power, customers will not be able to use his previous "top up tip".
