How do I complain about an online casino in the UK?

Complain to the operator in writing first and ask for it to be logged as a formal complaint. If it is still unresolved 8 weeks later, you can take it to an Alternative Dispute Resolution provider, which a licensed operator must offer you free of charge.

Will the Gambling Commission get my money back?

No. The Gambling Commission regulates operators and can act on their conduct, but it does not decide individual disputes and cannot order an operator to pay you. The body that can decide your case is the operator's approved ADR provider.

What is a deadlock letter?

Written confirmation from the operator that your complaint has reached a final position, which lets you go to ADR immediately instead of waiting the full 8 weeks. An operator can issue one at any point, and you can ask for it.

How long does a casino have to resolve a complaint?

8 weeks from the day it received your complaint. After that you are entitled to take the dispute to an ADR provider free of charge. The clock starts when you complain, not when the problem happened.

What if the casino is not licensed in the UK?

None of the British protections apply — no 8-week rule, no free ADR, no segregated funds, no GAMSTOP. A debit card chargeback through your bank is usually the best remaining option, and chargeback windows are short. Report the site to the Gambling Commission as well.

What happened, in your own words

Keep it factual and in order. Dates, amounts, what you were told and by whom. Leave out how it made you feel — it does not help, and a shorter factual letter is taken more seriously.

Your letter

What happens next

1Send this letter to the operator's complaints address and ask for it to be logged as a formal complaint. Every licensed operator must have a published complaints procedure.
2If it is still unresolved 8 weeks after the operator received it, you can take it to an Alternative Dispute Resolution provider. The operator must offer you this free of charge, and must tell you which provider is the relevant one for your dispute.
3You can get there sooner. If you and the operator reach a final position before 8 weeks, ask for a deadlock letter — written confirmation that you can go to ADR immediately. An operator can issue one at any point.
4The Gambling Commission does not decide individual disputes and cannot order an operator to pay you. Reporting the operator to it is still worth doing, because it feeds their supervision and patterns get noticed — but it is a separate action from getting your money back, not a substitute for it.

The deadline that matters: 8 weeks from the day the operator received your complaint. That clock only starts when you complain, so send it now rather than waiting to see whether support sorts it out.

The mistake that costs people their complaint

Almost every page on this subject ends with “complain to the Gambling Commission”. That advice sends you somewhere that cannot help you, while the one deadline that can runs down.

The Commission regulates operators. It licenses them, it can fine them, and in serious cases it can take a licence away. What it does not do is decide your individual dispute or order anyone to pay you. Reporting an operator to it is genuinely worth doing — reports feed supervision and patterns get noticed — but it is a separate action from getting your money back, not a substitute for it.

The body that can actually decide your case is an Alternative Dispute Resolution provider. Every licensed operator must give you access to one, free of charge, once your complaint is 8 weeks old — or sooner if it issues a deadlock letter. That is the route, and the 8 weeks only starts on the day you complain.

Three things that make a complaint work

Ask for it to be logged as a formal complaint. A support ticket and a formal complaint are different things internally, and only one of them starts the 8-week clock.
Put it in writing. A phone call leaves you with nothing to show an ADR provider later. Everything that matters should exist as text you still have.
Make them name the term. “Breach of terms” is not a reason. Asking which clause, when, and how the amount was calculated is what turns a refusal into something an ADR provider can review.
