How to check whether an online casino is really licensed in the UK

What a UK licence actually is

A remote gambling licence issued by the Gambling Commission is not a badge a site buys. It is a permission granted to a named legal company to run specific gambling activities for customers in Great Britain, and it carries obligations that cost the operator money: segregated player funds, dispute resolution through an approved ADR body, participation in the GAMSTOP self-exclusion scheme, affordability and anti-money-laundering checks, and advertising rules.

The important consequence for you is practical rather than ideological. If a licensed operator refuses to pay you, there is a documented complaints route that ends with a regulator who can fine it or take the licence away. If an unlicensed operator refuses to pay you, there is no route at all — you are relying on a company you cannot name, in a jurisdiction you cannot reach, to change its mind.

A licence is therefore a floor, not a recommendation. Plenty of licensed casinos run mediocre bonuses, slow withdrawals and thin support. What the licence buys you is a name, an address, an obligation and somewhere to complain.

Step 1 — find the licence line in the footer

Scroll to the very bottom of the casino site. A UK-facing operator is required to say who it is and under which licence it is operating. The line usually reads something like: "XYZ Gaming Limited is licensed and regulated in Great Britain by the Gambling Commission under account number 12345."

Two formats are common. Some sites print the five- or six-digit account number. Others print the full licence number, which looks like 055148-R-331498-001: the first block is the account, the R marks a remote licence, and the remaining blocks identify the specific licence and its version. Either is enough to run the check.

What you are looking for at this stage is not just the presence of a number, but whose name is next to it. The trading brand on the door is very often not the licensed company. That is normal — one licensed company frequently runs a dozen brands — but it means the name in the footer is the one you carry into the register, not the name on the logo.

Step 2 — look the number up in the public register

The Gambling Commission publishes its business licence register openly. You do not need an account, and it is the same data the regulator itself works from: licensed businesses, every licence they hold with its status and activity, the domains each licence covers, and the trading names they are allowed to use.

Search for the account number or the company name from the footer. What you want to see is the company listed, the remote casino licence marked Active, and a start date that precedes today. A licence marked as surrendered, lapsed, revoked or suspended is not a licence you can rely on, whatever the site still says in its footer.

We mirror that register ourselves and expose it as a tool, so you can paste in a domain instead of hunting for a company name. It answers with the licensed company behind the domain, every active licence it holds, its other licensed domains and its permitted trading names.

Step 3 — check the domain, not just the brand

This is the step almost every guide skips, and it is the one that catches the real problem. UK licences list the specific domains an operator is allowed to use. A brand name appearing in the register proves very little on its own: names are not unique, and a copycat site can use a name that resembles a licensed one.

The domain is different. If the exact domain in your browser address bar appears against an active licence, you are on a site that operator is permitted to run. If the brand appears but the domain does not, treat that as unresolved — it may be a new domain the register has not caught up with, or it may be someone trading on a licensed brand's reputation.

This is why our own licence tool answers differently depending on what you paste. A domain that is absent from the register is a strong signal. A brand name that is absent from the register proves nothing much at all, and we say so on the page rather than dressing the gap up as a verdict.

What the register does not tell you

The register is authoritative about permission and useless about quality. It will not tell you how long withdrawals take, whether the welcome bonus is worth claiming, how the support team behaves at 2am, or whether the site voids winnings on a technicality.

It also lags reality by a day or so, because it is republished on a schedule. A licence surrendered this morning may still read Active this afternoon. For most purposes that is irrelevant; if you are checking a casino specifically because something has gone wrong, it is worth re-checking a few days later.

And it covers Great Britain only. An operator can hold a perfectly valid licence from Malta, Gibraltar, the Isle of Man or Curaçao and be entirely absent from this register. That is not evidence of anything except that they are not licensed for British customers — which does matter if you are one.

Red flags that survive a licence check

• The footer names a company but no number, or a number with no company. Both halves are required for the check to mean anything.
• The licence is real but held by a different company from the one taking your deposit, with no explanation of the relationship anywhere on the site.
• The site advertises itself as accepting UK players while the register shows no active remote casino licence — sometimes phrased as "licensed internationally" or "licensed in Curaçao, available worldwide".
• The domain redirects you to a second domain at sign-up, and that second domain is the one not in the register.
• The T&Cs name a jurisdiction for disputes that is not Great Britain while the marketing is aimed squarely at British players.

How we use this check ourselves

Every casino in our lists has to clear this check before it can be listed at all. We import the Gambling Commission register on a schedule, match each reviewed operator to it by licensed domain and trading name, and record the date we did it. An operator we cannot match is not quietly dropped — it keeps its review page and is labelled as unrated, with no outgoing link, because we are not willing to send anyone to a site whose licence we cannot see.

The line about licensing on each of our reviews is not typed in by an editor either. It is derived from the mirror, so it cannot claim more than the data supports, and it turns amber by itself when the register stops confirming the operator.

One domain, two licensees: the case that breaks the simple check

The three-step check above works for the large majority of sites. Here is the case where it does not, because it happened to us.

bet365.com resolves in the register to two separate companies. Hillside (UK Sports) ENC, account 55148, holds the betting entitlements. Hillside (UK Gaming) ENC, account 55149, holds bingo and casino. Both are correct answers to "who is licensed for bet365.com" and only one of them is the answer to "who is licensed for the casino".

Our own matcher originally took whichever entry the register returned first, which produced a casino review naming a licensee that holds no casino licence. It now prefers the company holding an active casino entitlement when a domain resolves to more than one, and there is a test that fails if that behaviour ever regresses.

The general lesson for anyone doing this by hand: when a domain returns several licensees, read the activity column rather than the first row. A licence for betting does not authorise casino games, and the company you would deal with in a dispute is the one licensed for the product you were playing.

This is also why we print the licensee on every review rather than a green tick. A tick compresses four facts into one symbol, and the four facts are where the useful information lives.

What the licence conditions actually oblige an operator to do

A licence is not a badge of quality, but it is not merely a permission slip either. It carries obligations that shape what a customer can expect, and knowing them turns "is it licensed" into "what does that get me".

Age and identity must be verified before you gamble, not at withdrawal. Customer funds must be held in a way that is disclosed to you, with a published protection rating — not protected, medium or high — that tells you what would happen to your balance if the company failed. An alternative dispute resolution provider must be appointed, and its decisions are binding on the operator. Self-exclusion must be offered, and the national scheme must be honoured. Deposit limits must be available. Advertising must not be misleading, and terms must be transparent.

Each of those is enforceable, which is what separates a British licence from a badge purchased from a jurisdiction with no supervisory capacity. The enforcement feed we mirror is the record of that enforcement actually happening, including penalties in the millions.

What it does not get you: any guarantee about payout speed, library quality, support hours or the return-to-player configured on the games. Those are commercial choices, and they are what the rest of a review is for.

Reading a register entry properly

• The account number is the stable identifier. Brand names change, domains move, companies are renamed; the account number persists and is what to search on.
• Activities matter. Casino, bingo, betting and gambling software are separate entitlements, and an operator may hold some and not others.
• Status is either active or it is not. A lapsed or surrendered licence on a site still taking deposits is the most serious finding this check can produce.
• Domains listed against the licensee tell you the group. If a site you are considering is not among them, ask why — a licensed company should have the domain it operates registered against its licence.
• Trading names are the other half of the same picture, and they often reveal a portfolio the brand does not advertise.
• A company with a licence in a different name from the one in the footer is not automatically wrong — corporate structures are layered — but it is the point at which to slow down and read rather than assume.

White-label brands and the name you will not recognise

A large share of British casino brands are not operated by the company whose name is on the site. They run on a platform belonging to a licensee that operates dozens of brands, and the footer names that licensee rather than the brand.

This surprises people and it is entirely normal. In this catalogue, one licensee stands behind sixteen trading names and another behind dozens of domains across several countries. Seeing an unfamiliar company in the footer of a casino you have heard of is not a warning sign by itself.

What matters is whether the name in the footer appears in the register, whether the domain you are on is listed against it, and whether the licence covers casino play. If all three hold, the arrangement is above board regardless of how many brands share it.

The consequence worth understanding is practical rather than legal: on a shared licence, the terms, the verification process, the complaints route and the enforcement history are usually shared too. Two brands that look like alternatives may offer you exactly the same recourse if something goes wrong, because the same company handles both.

What a licence check cannot tell you

It cannot tell you whether the operator pays quickly, answers support at night, publishes its RTP, or has a bonus worth taking. Those are the things people actually want to know, and none of them are in a register.

It cannot tell you whether the licensee has been penalised — that is a separate published feed, and we mirror it precisely because the register and the enforcement record are different sources that most sites conflate or ignore.

And it cannot tell you that a site is safe. It tells you that a named company is authorised, supervised and reachable, which is a floor rather than a recommendation. Nine brands in this catalogue hold entirely valid licences and carry penalties against their licensees; both facts are true at once and both are printed on their reviews.

Treat the check as the first filter, not the verdict. It removes the sites that should never have had your money, and it is the only step in choosing a casino that produces a definite answer.
