How To Make A Complaint About A Casino In The UK



Start With the Operator: Your First Port of Call

Every licensed casino in Great Britain must operate a formal complaints procedure as a condition of its Gambling Commission licence. Before escalating anywhere else, you are expected to raise the issue directly with the operator. Under the Commission’s rules, casinos should acknowledge a complaint within a set window , commonly 48 to 72 hours , and aim to resolve it within eight weeks.

Put your complaint in writing. Email beats a phone call because it creates a timestamped record. State your account details, the date and time of the disputed transaction or incident, the outcome you want, and any evidence you hold, such as screenshots, bonus terms or chat transcripts.

Keep your tone factual. Disputes over bonus terms, withdrawal delays and account closures make up the bulk of complaints, and clarity wins over volume every time. Ask for a written final response, sometimes called a deadlock letter, if the casino will not resolve matters to your satisfaction.

Check the operator’s terms first. Many complaints stem from misunderstanding wagering requirements or maximum bet rules attached to free spins and deposit bonuses. If the terms plainly support the casino’s position, you may save yourself weeks by reading them closely before firing off an email.

Escalate to the Independent Body

If eight weeks pass without resolution, or you receive a deadlock letter, you can take your case to an independent Alternative Dispute Resolution (ADR) provider. The Gambling Commission does not adjudicate individual disputes itself; it requires licensees to belong to an approved ADR scheme instead. The largest is IBAS (Independent Betting Adjudication Service), alongside others such as eCOGRA for certain operators.

ADR is free to you and binding on the casino, though not on you , you retain the right to pursue the matter through the courts. Decisions typically take between four and eight weeks, and the adjudicator will review the terms, the evidence and whether the operator acted fairly and consistently.

Prepare a concise case file: your original complaint, the casino’s final response, and supporting documents. Stick to facts. Adjudicators assess whether the operator followed its own published terms, so quote the specific clause at issue.

Bear in mind that ADR cannot force a casino to reverse a decision made under valid and clearly stated terms. Where terms are ambiguous, however, adjudicators often lean towards the consumer.

When to Involve the Gambling Commission

The Gambling Commission acts as regulator, not referee. It will not recover your money or rule on your individual case, but it does want to hear about operators breaching licence conditions , for example, refusing to pay legitimate winnings, misleading advertising, or failing to honour safer gambling commitments.

Use the Commission’s online contact form to report regulatory concerns. Include your ADR reference and the operator’s final response. Reports feed into the Commission’s wider intelligence picture; several enforcement actions and financial settlements have followed patterns of consumer complaints.

If you suspect a casino is operating without a licence, check the public register on the Commission’s website before depositing anything. Unlicensed sites offer no ADR route and no regulatory protection whatsoever.

Finally, keep records for at least twelve months and stay calm throughout. A well-documented, politely worded complaint resolved through the proper channels achieves far more than repeated demands , and the framework exists precisely so that fair outcomes are achievable.
