Casino disputes can be frustrating, especially when you’re convinced you’re in the right. In the UK, one of the key avenues for resolving issues with casinos and betting operators is the Independent Betting Adjudication Service (IBAS). IBAS is a free and impartial Alternative Dispute Resolution (ADR) service that adjudicates disputes between licensed gambling operators and their customers. In fact, IBAS handles the majority of gambling complaints in the UK, reflecting its central role in protecting players.
This guide explains what IBAS is, what types of casino disputes it deals with, how to submit a complaint step by step, and what to expect from the process. You’ll also see real examples of IBAS in action, learn about its limitations, and discover when to seek further legal help — such as through us – Player Protection Legal — if ADR alone isn’t enough.
What Is IBAS and Its Role in UK Gambling?
Established in 1998, the Independent Betting Adjudication Service was designed to give bettors a formal way to challenge how a bet or game was settled. Today, IBAS is an ADR provider approved by the UK Gambling Commission (UKGC), meaning all UK-licensed casinos and bookmakers must offer ADR to customers with unresolved disputes.
IBAS is funded by registered operators, not players, which ensures it’s free for the consumer. Importantly, it only deals with disputes involving UK-licensed operators. If you play at a regulated online casino, there’s a high chance it’s registered with IBAS or another UKGC-approved ADR.
While IBAS rulings are technically non-binding in law, operators that sign up agree to abide by them (for disputes up to £10,000). In practice, licensed operators almost always comply — failure to do so risks regulatory action. Over its history, IBAS has adjudicated tens of thousands of disputes, with its 100,000th case recorded in 2025.
Types of Casino Disputes IBAS Handles
IBAS can handle a broad range of issues, including:
- Withheld winnings and delayed withdrawals – Commonly caused by extended “verification” checks or disputed terms. IBAS examines whether the casino’s actions are justified and consistent with its stated rules.
- Bonus and promotion disputes – For example, if you met all wagering requirements, but your winnings were voided. IBAS considers the clarity and fairness of bonus terms.
- Game or technical errors – If a software malfunction impacts your result or payout, IBAS reviews logs and applies fairness principles.
- Unfair terms and conditions – IBAS checks if rules were disclosed clearly, applied consistently, and met consumer law standards.
- Account and identity disputes – Issues such as wrongful suspension or frozen funds can be brought to IBAS.
It’s important to note that IBAS deals with specific transactional disputes — not general complaints about customer service or responsible gambling failings.
Step-by-Step: How to Submit a Complaint to IBAS
1. Use the casino’s internal complaints process first
The UKGC requires players to give the operator a chance to resolve the matter before involving ADR. You usually need to wait up to eight weeks or until you get a “deadlock” letter.
2. Register with IBAS
Visit the IBAS website, create an account, and verify your email.
3. Complete the adjudication form
Clearly explain:
- What happened and when.
- What outcome you expected.
- What actually happened.
- How the casino responded.
4. Upload supporting evidence
Include screenshots, transaction logs, correspondence, and relevant terms.
5. Wait for IBAS to contact the operator
IBAS will request the casino’s version of events, including evidence and applicable terms.
6. Panel review and questions
The adjudication panel may seek clarifications from you or the operator.
7. Receive the decision
Both parties receive the ruling simultaneously, with reasons explained.
What to Expect During the Process
- Timeline – Most cases resolve within 8–12 weeks, but complex disputes can take longer.
- Communication – Keep an eye on your email and respond promptly to IBAS requests.
- Outcome – If you win, the operator should comply quickly. If you lose, the ADR process ends unless you pursue legal action.
- No cost – The service is free, and there’s no financial risk in using it.
Examples of IBAS in Action
Sportingbet bonus dispute – A customer qualified for an enhanced-odds payout but was later told they were ineligible due to a prior “arbitrage” flag. IBAS ruled that the exclusion should have been made clear before the bet, and ordered Sportingbet to pay the enhanced winnings.
Luckster withdrawal delay – A player faced weeks of stalling over a withdrawal request, with repeated ID document demands. After the player complained to IBAS, the panel ruled in their favour and the funds were released.
Limitations of IBAS
- Scope – IBAS only handles specific transactional disputes. It won’t cover general service complaints, allegations of game rigging, or problem gambling concerns.
- Licensed operators only – Unlicensed offshore sites are out of IBAS’s jurisdiction.
- Enforcement – IBAS can’t legally force payment, though UKGC oversight makes non-compliance rare for licensed operators.
- Monetary cap – Binding decisions apply to disputes up to £10,000.
- No distress compensation – IBAS won’t award damages beyond the disputed amount.
- Time limits – Typically, within 12 months of the issue.
When IBAS Isn’t Enough — Next Steps
If IBAS can’t help or the dispute remains unresolved, you can:
- Report to the UKGC – For regulatory breaches.
- Complain to the ASA – For misleading adverts.
- Use Small Claims Court – For up to £10,000.
- Seek legal advice – Services like Player Protection Legal can handle complex or high-value disputes, and advise on court action or Section 75 credit card claims. If IBAS can’t resolve your case and you paid with a credit card, you may also be able to recover your money through a Section 75 claim. Under UK law, credit card providers share liability for purchases over £100, which can include disputed casino deposits.

- Check other ADR providers – Some operators use alternatives like eCOGRA.
- Leverage community support – Forums and social media can apply public pressure.
Conclusion
IBAS is a key protection tool for UK casino players, offering a free and fair route to resolve disputes over winnings, bonus terms, and game outcomes. By following the correct steps — and preparing clear evidence — you can significantly improve your chances of a favourable decision.
If IBAS can’t resolve your issue, remember that it’s not the end of the road. From regulatory complaints to court action and professional legal support, there are further options to fight for what you’re owed.
