It is important that you know that your meter uses your money in two ways:
- To pay for the energy you use
- To collect any arrears you may owe from past bills
If a previous bill is being collected, in nearly every case your meter will tell you how much you still have to pay. With a Smartcard meter however you should call the Pay As You Go help-line whose numbers you can find above. When your bill is cleared the meter will automatically stop collecting the extra amounts.
If you are repaying a past bill and your circumstances change such that it makes it hard for you to make repayments, then please phone the Pay As You Go help-line for advice.
