BROADBAND · BILLING
KEY FACTS
  • Common billing errors include incorrect charges, charges after cancellation, unexpected fees, and price applied wrongly.
  • Raise a billing dispute with the provider, clearly stating the error and the correction you want, with evidence.
  • The Direct Debit Guarantee can allow a refund of a payment taken in error, through your bank.
  • If unresolved, escalate to the ombudsman after six weeks or at deadlock; small claims is a further route.

Broadband bills are not always right, and an incorrect charge is not something you simply have to pay. Whether it is a fee you did not expect, a charge after you cancelled, or the wrong price applied, billing errors are challengeable through a clear process. Knowing the steps, and the protections available, gets errors corrected and money refunded.

Spotting billing errors

Check bills against what you agreed. Common errors include the wrong monthly price, charges for services or add-ons you did not take, fees applied after you cancelled, double charges, or an out-of-contract price applied when you should still be on a deal. Comparing each bill to your contract and your records is how you catch these before they accumulate.

Raising the dispute

Contact the provider and raise the billing dispute clearly: identify the specific charge, explain why it is wrong, and state the correction you want, a refund, a credit, or a corrected bill. Reference your evidence, the contract terms, cancellation confirmation, or previous bills. Put it in writing so there is a record, and note the date.

The Direct Debit Guarantee

If a payment has been taken by Direct Debit in error, the Direct Debit Guarantee is a powerful protection. It entitles you to a prompt refund from your bank of an amount taken in error under the scheme. This is separate from resolving the underlying dispute with the provider, but it can get incorrectly taken money back quickly while you sort out the substance.

Billing dispute process

StepAction
1Identify the specific error against your contract and records
2Raise it with the provider, stating the correction wanted
3Use the Direct Debit Guarantee for a payment taken in error
4Escalate to ADR after six weeks or at deadlock
5Consider small claims if the dispute remains unresolved

Escalating if unresolved

If the provider will not correct a genuine error, raise a formal complaint and, if it is unresolved after six weeks or you receive a deadlock letter, take it to your provider's approved ADR scheme such as CISAS, which can order a correction or refund. For some disputes, the small claims court is a further option. Your records and evidence are what make any of these routes succeed.
