The number of households being forced onto prepayment meters has rocketed over the past few months - but what are your rights?
With standard credit meters, you pay for energy after you've used it but with prepayment meters, you have to pay in advance and the cost of energy is usually more expensive.
Citizens Advice revealed that around 600,000 people were switched onto a prepayment meter last year and warned that a further 160,000 people could be put on them before the end of the winter if nothing changes.
