You can be in debt on prepay meters if you re not topping up enough to pay the daily standing charges which now is around 48 p to 51 p a day .

I haven't topped up in a while because of the government vouchers.  I still have credit to last another month. I'm asking because I read somewhere someone was penalised for not topping often enough.. I know it sounds crazy
