Treat credit as a dated snapshot
An account can show credit because payments are ahead of charges at the point the supplier displays it. Check the statement date, the latest readings, the billed-through date and any charges still expected.
Check what is included in the balance
Look for pending bills, estimated usage, scheduled payments, debt or earlier adjustments. A balance can change after a new reading or statement, so the amount alone does not prove that the whole balance is available to refund.
Keep evidence for a clear question
Save the statement, the date you asked about the credit and the supplier response. Ask which charges and payments are included and what balance the supplier expects after the next bill.
Illustrative example: credit is not the same as a refund
Illustrative example only: an account showing £180 credit after several monthly payments may still have a bill due for the latest usage. Ask the supplier to show the billed-through date and expected next charge before deciding how much, if any, is available to return.
A practical refund request
You can ask: “Please explain the balance shown on my account, the date it was calculated, any charges or payments still due, and whether a refund is available. If it is not, please explain what information or future bill is being allowed for.” Keep the request focused and use the supplier’s secure channel.
If the supplier will not explain the balance
Keep the statement, readings, payment history and response. Ask the supplier to identify the specific transaction or expected charge that prevents resolution. If the answer remains unclear, use the complaint route; do not assume that switching or cancelling a payment settles the account.
Choose the next route
Use the credit-and-refund guide for an action checklist, the Direct Debit guide if the payment is changing, or the complaint guide if the supplier will not explain the balance.
