Firstly, please ensure an actual meter read has been submitted. If we have used an estimated reading on your final bill, we will be unable to refund any remaining credit until we can bill you using an accurate reading. Then, once your final bill is issued and any other accounts you have with us have all been paid, any remaining credit balance will be refunded to you automatically within 14 calendar days. This will be paid in the same way your original payment was made.
