Every legally operating online casino serving players in the United Kingdom must hold a licence from the Gambling Commission. This is not a courtesy or a marketing badge. It is a legal requirement under the Gambling Act 2005, and sites that skip it are trading unlawfully. Around 3,000 operator licences are currently active, covering everything from household names to niche brands offering Bitcoin free spins and other crypto-friendly promotions.

Checking a licence takes minutes, yet plenty of players skip it. That is risky. Unlicensed sites offer no recourse through the regulator, no access to dispute resolution services, and no protection under the United Kingdom’s consumer safeguards. Here is how to verify a casino properly, using the same checks the trade press and compliance teams rely on.
Start With the Gambling Commission’s Public Register
The quickest route is the Gambling Commission’s online register, which lists every licensed operator and their trading names. Search the brand name exactly as it appears on the site, not the parent company, then cross-reference the domain. A legitimate casino will display its licence number in the footer of every page, usually phrased as „licensed by the Gambling Commission” with a link.
Click that link. It should take you to the operator’s entry on the register, showing the licence number, the licensed entity, and the status. If the footer text is plain, the link is broken, or the number returns nothing, treat it as a red flag. Around 40% of complaints escalated to the Commission in recent years involved sites that either misrepresented their licensing status or held no licence at all.
Pay attention to the entity name too. Large groups hold separate licences for different brands, and remote casino and remote betting are distinct permissions. A site licensed for bingo but running slots without the remote casino permission is operating outside its terms.
Read the Licence Details and Check the Small Print
The register entry tells you what the operator can actually offer. Look for „remote casino” in the licence conditions if you plan to play slots or table games, and check whether the licence covers the specific domain you are visiting. Operators sometimes launch new domains that are not yet listed, which is a technical breach even for otherwise compliant businesses.
Scan the terms and conditions for the licensed entity’s registered address and company number. These should match the register. Sites that hide this information, or list a vague offshore address with no UK presence, deserve scepticism. The Commission requires clear display of licence details, and failure to provide them is enforceable.
Also check the site’s complaints procedure. Licensed operators must be members of an alternative dispute resolution scheme, and the details should be easy to find. If the only contact route is a chat widget that never answers, that absence of accountability often signals deeper problems. Reputable brands publish their ADR provider by name.
Verify the Extras That Come With a UK Licence
A valid licence brings concrete protections that are easy to test. Deposits should be ring-fenced in separate accounts, meaning player funds are protected if the operator fails. The site must offer self-exclusion tools, deposit limits, and time-out options, all of which should be reachable within a couple of clicks from the account page.
Age and identity verification must happen before withdrawal, not just at sign-up. Licensed sites run checks against electoral roll and credit reference data, and any winnings are paid in GBP without hidden conversion fees. If a casino insists on paying out in another currency or through an unregulated processor, question it.
Finally, compare the offer against the licence conditions. Bitcoin free spins promotions, welcome bonuses, and cashback deals must be advertised fairly, with wagering requirements stated clearly. A licensed operator will spell out the terms; an unlicensed one will bury them. When a brand quotes its terms properly, shows its licence number, and links to the register, you are dealing with a regulated business. Anything less is a gamble the regulator never approved.
