What to do when an online casino withholds your winnings

Stalled withdrawals, endless verification loops and voided winnings: the order to do things in, the routes that exist, and the mistakes that weaken a claim.

If a casino will not pay out, or is withholding winnings you have already been told are yours, work through these five steps in this order. The order matters, because some early mistakes are hard to undo.

CauseHow to tellWhat to doHow long it takes
Routine identity or KYC checkA document request appears before or shortly after your first withdrawalSend everything asked for in one go and keep a dated copyUsually 24 to 72 hours on a UK-licensed site; can run to weeks offshore
Source-of-funds reviewThe request goes beyond ID to bank statements, payslips or an explanation of how you fund play, usually after a large win or a fast increase in stakesProvide clear documents once; ask in writing what specifically is still missingDays to several weeks; a UK licensee must give a reason if it runs long
Bonus or wagering term disputeWinnings are reduced or voided and a bonus, free spin or promotion was active on the accountAsk for the exact clause relied on and compare it against the terms you were shown when you opted inResolved on written complaint, typically within the operator’s own published response time
Balance confiscated for an alleged rule breachThe account is closed or the balance zeroed with a vague reference to “terms” or “account misconduct” but no clause namedDemand the specific term in writing before accepting the decision or any partial offerNo fixed period; escalate once a written refusal exists
Payment processing delayThe operator says funds have been sent but nothing arrives, or a payment reference is missingAsk for the transaction or payment reference and the exact date it was sentE-wallets often same day; cards and bank transfers usually 1 to 5 working days
Formal complaint stalls with no answerWeeks pass after a written complaint with no final responseEscalate to the operator’s independent adjudicator (UK-licensed sites) or check the licence route belowFree adjudication opens after eight weeks or a deadlock letter, whichever comes first

If the money is already being withheld, our Curaçao refunds service and a free eligibility check will tell you which route your operator’s licence actually gives you.

  1. Complete verification once, in full. Send every identity and source-of-funds document the operator has asked for in one go, and keep a copy of what you sent and the date you sent it.
  2. Get the refusal in writing. Ask for the exact reason for the delay and the precise term being relied on, and insist on a written answer rather than a live-chat one.
  3. Preserve the whole record. Screenshot the pending withdrawal, export your cashier history, and save the terms as they read today, before anything can be changed above your head.
  4. Complain formally to the operator. Use its published complaints procedure, in writing, with the dates and amounts set out plainly, and keep every reply it sends.
  5. Escalate to the right body. For a Gambling Commission-licensed site, take an unresolved complaint to its independent adjudicator, such as IBAS, free of charge, once the operator’s process is exhausted or eight weeks have passed. For an offshore site there is no UK adjudicator, so the licence regime behind the operator and the strength of your evidence decide what is realistic.

A withheld payout usually follows a pattern: one verification request, then another, then a term that was never clearly signposted when you played. Some of those checks are a genuine legal requirement, but how and when you respond still shapes what you can recover. If you are not certain which body sits at step five for your casino, the free complaint route finder asks three questions and returns the ordered path.

What can I do if a casino is withholding my winnings?

If a casino is withholding your winnings, you are almost certainly in one of four situations: a delayed withdrawal, a KYC or source-of-funds review, winnings voided under a term, or a balance confiscated outright. Whichever it is, preserve the evidence before you argue: screenshot the balance and the pending withdrawal, export your transaction history, and save the terms as they read today. Then put a written complaint to the operator and ask for the exact term relied on. If the site is UK-licensed and the complaint stalls, you can escalate free of charge to the independent adjudicator its licence provides, such as IBAS; offshore, the route is whatever the operator’s own licence sets out. Where the sum is large or the explanation keeps changing, a specialist assessment of a withheld payout can be worth it. Be clear-eyed: a loss alone is not a claim, a breach does not automatically create a repayment right, and no honest adviser promises recovery.

Each of the four situations is worked through in the sections below, and where substantial winnings are withheld our withheld winnings service explains what a specialist assessment involves and what it needs from you.

Do not accept a partial offer yet

If an operator withholding your money offers to return part of a balance to settle, treat it as a position, not a conclusion. Accepting can close off stronger routes. Equally, do not close the account in frustration, because access to your own history is part of the evidence.

Get everything in writing

Move the conversation into writing and keep it there. Ask for the exact reason the money is being withheld, the term being applied, and a copy of your transaction history. Screenshot the cashier, the messages and any changing terms. A claim is only as strong as what you can show.

One channel warning: live chat rarely counts as a formal complaint, however clearly you put your case in it, because operators treat chat as an informal support query. Send the complaint through the operator’s published complaints email or form, name its complaints procedure, and keep proof it arrived, because that is what starts the clock the eight-week escalation rule runs on.

Slow down, document, then decide.

The order that protects a claim

Complete reasonable verification once, in full. Put the refusal in writing. Preserve the record. Then weigh the routes in order: the operator’s own complaints process comes first, and for sites licensed by the Gambling Commission you can take an unresolved complaint to the operator’s independent adjudicator, such as IBAS, once that process is exhausted or eight weeks have passed. You can also report the operator to the Gambling Commission, though it regulates operators rather than settling individual disputes or ordering refunds. Where the operator is licensed offshore rather than by the Gambling Commission, those adjudication routes do not apply and the focus shifts to the payment and evidence trail: see getting money back from an offshore casino. If the operator holds a Curaçao licence, how Curaçao licensing works for UK players explains which complaint routes its regulator does and does not provide. If a balance has been frozen or a win voided, see your options when an account is frozen. A free assessment will tell you, honestly, where your case stands.

Withdrawal restrictions have been tested before

Terms that restrict withdrawals are not a grey area the operator gets to interpret for you. Between 2016 and 2019 the Competition and Markets Authority, working alongside the Gambling Commission, investigated unfair terms and practices in online gambling and secured formal undertakings from major operators, including changes to terms that restricted players from withdrawing their own deposit balances and to bonus conditions that trapped funds. The case file is public at gov.uk. Two things follow for a withheld payout today. A term that blocks you from withdrawing your own deposits, imposes arbitrary instalment caps, or lets the operator confiscate funds for vague conduct reasons sits in exactly the territory that action covered, and quoting the CMA programme in a complaint shows the operator you know it. And fairness is judged on the term as it was applied to you, not on the fact that you clicked agree at sign-up.

Find your exact situation

This page sets out the ground rules that apply to every withheld or stuck payout, but most stalled withdrawals fall into a recognisable pattern, and each pattern has its own dedicated guide carrying the detail this overview deliberately keeps short. Match yours before going further:

If none of those matches cleanly, stay here; the sequence on this page holds whatever the surface pattern looks like. And if the casino itself is the question, our operator files record the licence position and documented concerns for dozens of named brands, several with withheld-payout histories.

The first 48 hours after a payout is withheld

What you capture in the first two days often decides what a case can prove months later, because the operator controls the account and controls what you are able to see inside it. Before pressing support for answers, quietly secure your own copy of everything:

  • A screenshot of the pending withdrawal showing the amount, the payment method and the date requested.
  • Your full cashier record, exported or photographed page by page, covering deposits as well as the balance.
  • The terms and conditions as they read today, saved with the date, so a later edit cannot rewrite the past.
  • The bonus terms if any promotion was active on the account, however incidental it seemed at the time.
  • Every message already exchanged, including chat transcripts, which many sites will let you email to yourself.

Only then open the conversation, and open it in writing. The reason for the ordering is simple: accounts under dispute sometimes lose features, and a record you hold yourself cannot be edited above your head. And if the temptation in these first hours is to skip the operator entirely and go through your card provider instead, pause and read why rushing to your bank can backfire before deciding anything, because that route carries consequences that are easy to miss under pressure.

Reading the operator’s replies

Support responses in a withheld-payout dispute are written to scripts, and the scripts translate:

  • “Escalated to the relevant department.” A queue, not a review. No department is named and no date is attached because neither exists yet. Reply asking which department, reviewing what, and by when.
  • “Additional verification is required.” Legitimate the first time. A warning sign when it arrives after documents have already been accepted, because layered re-verification is a classic way of restarting the clock.
  • “Your account is under security review.” Frequently the prelude to a term being applied. Ask now, in writing, which term is under consideration; the answer, or the refusal to give one, becomes evidence either way.
  • “We appreciate your patience.” Filler that resets nothing. Treat it as no reply at all and keep your own timetable running.

None of these phrases answers anything, and that is their function. The discipline is to meet each one with the same four questions: who is looking at this, what exactly are they checking, under which clause, and by what date will there be a decision. Operators with a genuine answer give it; operators without one reveal that too.

UK and offshore: what a reasonable wait looks like

Expectations should differ by licence. On a Gambling Commission licence, identity checks are pushed to the start of the relationship: UK rules require operators to verify who a customer is before they gamble, which is why a fresh identity demand appearing only at withdrawal deserves scepticism on a UK site. Fair-terms obligations also mean processing windows have to be reasonable and stated up front. Weeks of unexplained withholding by a UK licensee is not normal, and it is itself a proper subject for a complaint. Offshore, the published terms often permit long processing windows, and the real timetable is set by the operator’s habits rather than any regulator’s expectations. There, the calendar that matters is the one you impose: dated requests, a dated complaint, and a dated escalation, so the delay is always measured against something you can show. Two identical delays can therefore mean very different things. On a UK site, a stalled month suggests either a genuine regulatory check nearing its end or a decision the operator is reluctant to announce, and both possibilities reward a firm, documented push. On an offshore site, the same month of withholding may simply be how the operator treats everyone, which tells you that patience alone will not move it and that the leverage has to come from elsewhere in your record. Either way, once the operator’s own process stalls, the formal escalation path, operator then IBAS then the regulator, is set out in how to complain about an online casino, step by step. If the sum at stake justifies it, a specialist assessment of a withheld payout can run alongside that escalation rather than instead of it.

How long should a casino withdrawal actually take?

There is no single statutory deadline, but ordinary practice is well established, and measuring your delay against it turns a vague wait into a specific, dated complaint.

StageOrdinary practice on a UK-licensed siteWhen the delay becomes a complaint
Withdrawal approved internallyWithin the operator’s own published processing window, commonly 24 to 72 hoursThe published window passes with no decision and no reason given in writing
Identity checksCompleted before you were allowed to gamble, so rarely repeated at cash-outA fresh document demand appears only at withdrawal, or documents already accepted are requested again
Funds reaching youE-wallets often the same day; cards and bank transfers usually 1 to 5 working days after approvalThe operator says the money has been sent but nothing arrives and no payment reference is given
Formal complaintA final response within eight weeks at mostEight weeks pass, or a deadlock letter arrives; free ADR such as IBAS opens either way

Offshore, published terms often permit longer windows, so the same table works differently there: measure the operator against its own published timeframes, in writing, and let every missed one become an exhibit. Either way, the number that matters most is eight weeks, because on a UK-licensed site that is the point at which the dispute stops being a private conversation and becomes a free referral to an independent adjudicator.

Operator files for the brands people ask about most

Most of the largest sites by search volume hold a Curaçao licence rather than a Gambling Commission one, which changes which routes above apply. Our operator files record the licence position, the licensed entity and what each operator file records, including any documented payout complaints and their sources; several carry their own dedicated withheld-payout guide. Which licence type your casino holds also decides the escalation route: see the licence-type breakdown below this article.

If your casino is not on this list, our full operator directory covers dozens more, and the licence checker confirms what a brand actually holds against the current register.

When a withheld payout is large

A small stalled withdrawal and a five- or six-figure one are not the same problem, because the operator’s incentives change with the size of the sum. Two patterns turn up again and again once the amount gets large.

  • Source-of-funds holds get slower and go further. A win of a few hundred pounds or dollars might clear on a standard ID check; a win running into the thousands routinely triggers a source-of-funds request, asking not just who you are but where the money you played with came from: bank statements, payslips, savings records or an account history. This is a genuine check many licensees are required to run, but it should still have an end point. Ask, in writing, what remains outstanding and by what date a decision is expected; an open-ended request with no criteria is itself worth challenging.
  • VIP hosts go quiet. Accounts that were assigned a personal VIP host while depositing often find that host unreachable the moment a large withdrawal is requested. Treat silence from a VIP contact as no different from any other unanswered complaint: it does not pause your own timetable, so move the request into the operator’s formal, written complaints channel rather than waiting on a reply that may not come.
  • When pursuing a claim is worth it. A specialist assessment tends to make sense once three things line up: the sum withheld is substantial (commonly a few thousand pounds or dollars upward, in either currency), the operator’s written reason does not match your account record or has changed more than once, and you already hold the evidence: the pending withdrawal, your cashier history and the term being relied on. Below that, the free routes, a written complaint and, on a UK licence, adjudication through IBAS, usually resolve things without any specialist input at all. For a Curaçao-licensed operator specifically, our Curaçao refunds service explains what an assessment involves when the sum justifies it, and a free, no-obligation assessment establishes where you stand before you commit any further time to the case.

Common questions

Why is the casino not paying out my winnings?

Usually a verification or source-of-funds check, or a term being applied to a withdrawal. Some checks are a genuine legal requirement, but the order you respond in matters, because some early mistakes are hard to undo.

Complete reasonable verification once, in full; get the refusal and the term being relied on in writing; and preserve your transaction history. Do not close the account or accept a partial offer before you understand your position.

Sometimes. Routes include the operator's own complaints process and, for UK-licensed sites, its independent adjudicator such as IBAS. Which applies depends on the operator's licence and the strength of your evidence, and where an operator breached its duties recovery may be possible.

It depends on the route and the operator's licence. Time limits can be short, so it is best to act early, keep the dates straight, and preserve your account and payment records from the outset.

Put the refusal in writing and get the exact term being relied on, then run the operator's own complaints procedure with the dates and amounts set out plainly. If the site holds a Gambling Commission licence, an unresolved complaint goes free of charge to its independent adjudicator, such as IBAS, once that process is exhausted or eight weeks have passed. If it is licensed offshore, there is no UK adjudicator, so the regime behind the licence and the strength of your record decide what is realistic.

It can withhold a payout where a term genuinely applies, for example an unfinished identity check or a clear breach of the bonus rules, but it cannot rely on a term that was never properly signposted or apply one unfairly. Whether a refusal stands turns on which clause is being used and on what your account record actually shows, which is why getting the clause named in writing matters so much.

Only where a term genuinely applies and was fairly applied, for example an unfinished verification check or a clear bonus-rule breach. A casino cannot withhold winnings indefinitely under a vague review, or rely on a term that was never properly signposted. Get the clause in writing, then test it against your account record; that comparison decides most withholding disputes.

There is no single legal deadline. A UK licensee must state its processing times up front, apply terms fairly and finish checks within a reasonable window, so weeks of unexplained withholding is itself a proper ground for complaint. Offshore, published terms often permit long windows, so impose your own timetable: dated requests, a dated complaint, then escalation.

Sometimes. A withheld payout can support a breach-of-contract claim, and duty-based claims exist where an operator's conduct fell short of what its licence required, generally within a six-year limitation period. The free routes come first, though: a written complaint, then free ADR such as IBAS after eight weeks, cost nothing and resolve most disputes. Court is a last resort, the outcome of any claim is never promised, and the record should be assessed before anything is issued.

Yes, in narrow circumstances: where identity or source-of-funds verification is genuinely incomplete, or where a clear term was actually breached and is being applied fairly. What does not stand is a refusal with no stated reason, or one resting on a vague or unfair clause, because fairness is judged on the term as applied to you, not as drafted. Ask for the exact clause in writing; a refusal that cannot name one is challengeable.
