If Citizens Advice supports this, then it must be a good thing.

Citizens Advice Bureau (CAB) has warmly welcomed the introduction of a ‘Smart Pre-Pay option’ by energy giant E.ON.

Smart pre-pay offers prepayment customers the option of alternative ways to top up and the same monthly prices that direct debit customers pay.

E.ON has launched a Smart prepayment meter pilot, with ‘Smart Pay As You Go’ being made available to 30,000 eligible E.ON customers in 2015.

According to E.ON, Smart prepayment customers could save up to £104 per year by switching to the cheapest tariff available.
