Every legitimate UK-facing casino must hold a licence from the Gambling Commission, and checking that licence takes about two minutes. Yet thousands of players still sign up to sites without confirming who regulates them. The Gambling Commission currently licenses roughly 3,000 operators across remote and non-remote activity, and any site targeting UK players without one is trading illegally. This guide shows you exactly where to look, what each licence type means, and which red flags should stop you entering card details. For more details, visit deposit bonus guide uk 2026.
Where to Find and Verify a Licence Number
Scroll to the footer of any casino site. Licensed operators are required to display their Gambling Commission account number, usually a string of digits alongside a link to the regulator. Copy that number and head straight to the Gambling Commission’s public register at gamblingcommission.gov.uk. The search tool lets you look up any business by name or account number, and it returns the licence status, the trading names covered, and the specific activities permitted.
What you should see: a “Granted” or “Active” status, your chosen brand listed among the trading names, and remote casino permission included. If the register shows “Surrendered”, “Revoked” or “Suspended”, walk away immediately. A revoked licence means the operator is no longer permitted to transact with UK customers, regardless of what the homepage claims.
One important nuance: a single licence can cover several dozen trading names. Larger groups often hold one account number across multiple brands, so finding the parent company on the register is just as valid as finding the brand itself. Check the trading names tab carefully before assuming a mismatch.
The UK regime differs from offshore arrangements. Sites licensed in Curacao, Anjouan or Kahnawake do not hold Gambling Commission authorisation and cannot lawfully advertise to UK players. If a casino’s footer shows only a foreign regulator and no UK account number, that is a compliance problem, not a technicality.
Reading Licence Conditions and What They Protect
A Gambling Commission licence is not a rubber stamp. It carries dozens of conditions covering customer fund protection, fair odds, complaint handling and responsible gambling tools. When you verify a licence, you are confirming the operator must comply with rules on segregated player funds, a minimum 72-hour cooling-off period on new account bonuses, and access to dispute resolution through an approved ADR provider.
Licence conditions also mandate participation in GAMSTOP, the national self-exclusion scheme. Any operator genuinely licensed for UK remote gambling will reference GAMSTOP in its responsible gambling section. Its absence is a strong signal the site is unlicensed.
Fines tell their own story. The Commission has issued penalties running into the millions of pounds against operators for social responsibility and anti-money laundering failures, including a £19.2 million settlement in one high-profile case. These enforcement actions appear on the regulator’s website, so you can check whether a brand has a history of breaches before trusting it with a deposit.
A Quick Checklist and Common Red Flags
Run through this sequence every time you consider a new casino. It takes less time than reading the bonus terms, and it matters far more.
- Locate the licence number in the site footer and confirm it on the Gambling Commission register.
- Check the trading names list includes the brand you are using.
- Confirm “Remote Casino” appears among permitted activities.
- Verify GAMSTOP and GamCare references in the responsible gambling pages.
- Search the regulator’s enforcement notices for the operator’s name.
Red flags deserve equal attention. A missing footer licence, a number that returns no register results, a PO Box address in a jurisdiction with no UK authorisation, or terms that avoid naming any regulator at all. Any single one of these should end your consideration of the site.
Finally, remember the 18+ age requirement and the £2 maximum stake on slot-style games introduced under UK rules. Licensed operators enforce both; unlicensed sites rarely do. Checking a licence is the single most effective protection you have, and it costs nothing but a couple of minutes.
