Every gambling operator accepting wagers from UK players must hold a licence from the Gambling Commission. Anyone offering casino games without one is trading unlawfully, and the risks to players are significant. Money held by unlicensed sites has no regulatory protection, and winnings can vanish along with the company behind them. Check out additional details at see offers.
Reporting these operators is straightforward, and it genuinely matters. Complaints from the public feed directly into the Commission’s intelligence work, which last year handled tens of thousands of enquiries and used player reports to shut down dozens of illegal operations. Below is a practical walkthrough of where and how to raise concerns.
Where to Send a Report
The Gambling Commission is the principal regulator for Great Britain, covering England, Scotland and Wales. Its online reporting form lets you flag an unlicensed operator, a suspicious advert, or a site that appears to target UK customers without the required permission.
Action Fraud, run by the City of London Police, is the correct route when money has already been lost. Reports logged there are assessed for investigation and shared with policing partners. If you have been defrauded by a site posing as a legitimate casino, file with Action Fraud first, then inform the Commission.
For misleading advertising, the Advertising Standards Authority accepts complaints about gambling promotions appearing in UK media. The Committees of Advertising Practice code requires all gambling ads to be socially responsible, and the ASA can force amendments or removal.
- Gambling Commission , unlicensed operation or UK-facing site without permission
- Action Fraud , financial loss, fraud, or fake casino brands
- Advertising Standards Authority , misleading or irresponsible promotions
- Local trading standards , misleading commercial practices
What to Include in Your Complaint
Detail is everything. A report containing the operator’s web address, the date and time you noticed the activity, and screenshots of the registration or deposit pages is far more actionable than a general complaint. Regulators look for evidence that a site is accepting UK players, such as sterling deposits, UK payment methods, or UK-facing terms and conditions.
Keep records of any deposits, withdrawals and correspondence. If the site refused to pay winnings, note the exact wording used and the dates involved. Payment processors also welcome information, since card providers and e-wallets routinely withdraw services from unlicensed merchants.
Responsible licensed operators make verification easy, publishing their licence number and displaying the Commission’s logo. The best UK casinos list these details prominently, and checking for them takes seconds. A legitimate site will never ask you to waive your right to complain to a regulator or an alternative dispute resolution provider.
Protecting Yourself and Recovering Funds
If you deposited with a card, contact your bank promptly and explain that the merchant was operating without a licence. Chargeback rules give UK cardholders a route to recover funds in many cases, though success depends on timing and the evidence provided.
Check whether the operator appears on the Commission’s list of unauthorised sites, which is published and updated regularly. Should a website claim to be licensed but quote a number belonging to another company, report that misrepresentation as well , impersonation is treated seriously.
Finally, speak to a support service if an unlicensed site has caused you stress or financial harm. GamCare runs a free national helpline on 0808 8020 133, available every day, and its advisers can guide you through both reporting and practical recovery steps.
