What can I do?
You first need to collate and review your historic billing
You may find you have underpaid or overpaid in the past, leaving you with a potential bill to pay when you move to a new supplier, or perhaps be due a rebate.
Confirm your supply details:
Your site address, meter serial number and billing address need to be checked for accuracy.
Read your meters: It is important to ensure any transfer of supply is accurate.
