Start with the operator
For a dispute with a Gambling Commission licensed business, begin with the operator’s formal complaint process. State the account, transaction, dates, amount, disputed term and requested outcome. Attach the relevant evidence and keep a complete copy. The Commission’s public guidance says the business has up to eight weeks to resolve the complaint.
A support chat is not always a formal complaint. Ask where the complaints procedure is published, send the complaint through the stated channel and request acknowledgement. Keep the original terms and promotion as they appeared when the transaction occurred.
When ADR becomes available
A Gambling Commission licensed operator must offer access to an approved Alternative Dispute Resolution provider for an unresolved gambling transaction dispute. ADR normally follows the operator process: after a final response or once eight weeks have passed, the operator should explain which provider can consider the case.

The Gambling Commission regulates businesses and uses complaint intelligence, but it does not decide individual contractual disputes or order a payment for a player. ADR, the courts and other specialist bodies have different roles. Check the scope and deadline before escalating.
| Stage | Action |
|---|---|
| 1. Evidence | Save terms, account history, payment references, verification messages and support transcripts. |
| 2. Formal complaint | Write to the operator using its published complaint procedure. |
| 3. Final response or eight weeks | Request the deadlock/final response and the relevant ADR details. |
| 4. ADR | Submit the focused transaction dispute with the operator record and evidence. |
| 5. Other advice | Consider qualified advice where ADR does not apply or the value and jurisdiction justify it. |
What changes with an overseas casino
A casino licensed only overseas does not enter the Gambling Commission complaint and approved-ADR framework merely because a UK resident used it. The terms may select another governing law, regulator or dispute service. Confirm whether that body accepts complaints from players, what evidence it requires and whether its decision is binding.
Enforcement can be difficult where the company, payment processor and player are in different jurisdictions. Do not pay an unverified recovery service, disclose a crypto seed phrase or grant remote access to a device. For a substantial loss or complex cross-border dispute, seek advice from an appropriately qualified professional.
Reporting is different from resolving a dispute
A report to the Gambling Commission about unlicensed activity, underage gambling, money laundering or another regulatory concern can support enforcement. It is not the same as asking for an individual withdrawal to be paid. Keep the two objectives separate and use the form intended for each issue.
Payment-provider contact may be appropriate for an unauthorised transaction, processing error or trace request, but a chargeback should not be presented as a shortcut for reversing a genuine gambling loss. Give the bank accurate information and preserve the operator transaction record.
