How to Complain to IBAS When a Bookmaker Won’t Resolve a Dispute

Submit the complaint in writing, using the bookmaker’s stated complaints channel rather than ordinary customer support. Set out the disputed bet or transaction, relevant dates, account details, amount claimed, and the remedy sought. Attach key evidence, but retain the originals.

Follow every published escalation stage, even if earlier replies seem repetitive. For each contact, keep:

• complaint and case reference numbers;
• copies of messages, forms, and attachments;
• dates and times of calls or live chats;
• names or identifiers of staff involved;
• screenshots of the bookmaker’s complaints procedure.

Ask for a final response once the internal process is complete. This may also be called a deadlock letter and should confirm the operator’s final position and, where applicable, the route to IBAS.

A delayed or missing reply does not automatically make a dispute eligible. Check the bookmaker’s current response timetable and IBAS’s latest referral rules before filing, as waiting periods and submission deadlines may apply.

Before preparing a submission, search the current IBAS participant list for the legal operator, not merely the bookmaker’s trading name. The company name appears in the account terms, often alongside its registered address and licence information.

Check the following details:

• Dispute type: It should concern a gambling transaction, such as bet settlement, winnings or a transaction-linked balance—not simply poor service.
• Licence: Compare the named company and account domain with the regulator’s register. This follows the same principle as checking a bookmaker’s UKGC licence before registering.
• Jurisdiction: Confirm which country’s terms and regulatory regime governed the account when the transaction occurred. A familiar brand may use different companies in different markets.
• Deadline: Read IBAS’s current rules and submit within its stated filing period. Record both the date the complaint was first raised and the date of the operator’s final response.

A strong submission can be reduced to five linked points:

1. What happened: identify the bet or transaction, date, market, stake, odds, result, and operator decision.
2. Applicable term: quote the exact rule or promotion condition in force, supported by a screenshot or archived copy.
3. Operator’s interpretation: summarise the final response accurately, without guessing at motives.
4. Why it is disputed: explain how the evidence and wording support a different outcome.
5. Remedy sought: state the precise action and sum requested—for example, “Resettle the £20 bet at 4.00 and credit £80 in gross returns.”

Keep the narrative chronological and neutral. Remove insults, unsupported allegations of fraud, lengthy account histories, and grievances unrelated to the transaction. A genuine marketing complaint should follow advertising complaint routes under CAP and ASA rules, while the IBAS case remains centred on settlement or account terms.

After submission, IBAS may first verify that the dispute is eligible and that the bookmaker has completed its complaints process. It may request missing terms, account records, correspondence, or proof of the amount claimed. The bookmaker’s response may introduce records or arguments not seen earlier.

Treat every request as part of the evidence trail:

• Answer each question directly, using the same dates, transaction references, and attachment names as the original submission.
• Support each factual answer with a document; if none exists, say so and explain why.
• Correct new claims with evidence and the relevant rule, rather than simply repeating the original complaint.
• Reply promptly, note any deadline, and save each message and attachment in the case file.

Silence can leave an issue unresolved; repetition adds little. A concise response addressing the adjudicator’s exact concern is usually more useful.

Read the decision alongside the remedy originally requested. Note what was decided, any amount awarded, required account action, and applicable deadline. The reasoning also matters: a case may fail because IBAS lacked jurisdiction or evidence, rather than because the bookmaker’s position was accepted on every point.

If payment, a balance adjustment, or account action is due, check the account and payment method after the stated deadline. Save transaction references, screenshots, emails, and statements showing either compliance or the continuing shortfall. Any discrepancy should be raised promptly with the bookmaker and IBAS, quoting the case reference.

An IBAS adjudication is not the same as regulatory enforcement or a court judgment. Its effect, including whether and how an award binds the operator, depends on the current scheme terms and may vary with the amount involved. Licensing concerns can be reported to the relevant regulator, but a regulator will not necessarily recover an individual balance. Court action is separate and may involve fees, deadlines, and cost risk, so independent legal advice may be sensible before proceeding.

Jurisdiction remains important after a refusal or limited decision. A different ADR body, regulator, ombudsman, or local legal route may apply, particularly for disputes involving offshore bookmakers.

Keep the final decision with the complaint, evidence index, submissions, bookmaker responses, and proof of any payment or account change. Retain the complete file even after resolution.
