Emergency Credit
While you are responsible for remembering to top up your key or card, or buy tokens regularly to ensure you remain in credit and on supply, we know that emergencies can and do happen, so we build in a certain amount of emergency credit to your meter to tide you over until you can top up your key or card.
Your instruction booklet explains how to activate emergency credit and how to return your prepayment meter to normal use.
Remember, when your meter is in emergency credit mode, you are using electricity that you have not paid for and you will have to pay it back.
