E.ON is offering its cheapest tariffs to prepayment customers – the same as standard customers.
They will have to get a smart meter installed to take advantage of the cheapest rates, claiming customers will save around £104 a year.
The energy firm has launched a ‘Smart Pay As You Go’ (PAYG) pilot, which is initially available to 30,000 people.
It claims to be the first of the Big Six companies to make the offer to prepayment customers.
They will have the choice of paying bills through an app, online or over the phone and receive alerts before their balance runs out.
David Bird, E.ON’s Residential and Customer Operations Director, said: “We understand that for our customers there’s no ‘one size fits all’ when it comes to managing and paying for the energy they use. That’s why we want to provide a range of services that cater for all our customers’ needs.”
The new tariff will be more widely available for new and existing customers from 2016.
