Who runs this casino?
The Gambling Commission's own register can only be searched by company name. If you do not already know who is behind a casino, it cannot help you. This can.
Those 604 between them declare 2,135 web addresses, and this searches all of them backwards — from the address to the company. The rest of the register is land-based casinos, arcades, machine suppliers and lotteries, which declare no site at all.
How this works, and why it is here
Gambling Commission public register · 2,135 declared domains across 604 companies · read 31st July 2026
What it does when you press the button
- Reads what you typed as either a casino name or a web address, ignoring www. and anything after the domain.
- Checks it against the casino names we hold records for first, because that is the record every review page on this site is built from — so the tool and the reviews cannot name two different companies for the same casino.
- If that finds nothing, checks it against every domain declared to the Gambling Commission, then against the domain without its ending.
- Names every licensed company that matches — not just the first. More than one is common and it is shown rather than resolved for you.
- Prints the account number and links straight to that company’s page on the register, so you can confirm it without taking our word for it.
Why it exists
The Gambling Commission publishes all of this, and its own search only matches the names of licensed businesses. So it answers “what does Jumpman Gaming Limited run?” and cannot answer “who runs Barz Casino?” — which is the question a player actually has, and the one no casino answers on its own front page. This tool runs the register backwards.
What it cannot tell you
Whether the company is any good. It reads the register, so it can tell you who holds the licence and where they are registered, and nothing at all about how they behave. And a miss is not proof of anything: an address can be missing because it is new, because it is a page rather than a declared site, or because the operator holds no UK licence — three different situations this cannot tell apart, so it names all three instead of picking one.
01 What one company running many brands looks like from where you are standing
A licensed operator has to declare every web address it intends to run, and the largest portfolios in Britain are much larger than anyone browsing would guess. One account carries 227 declared domains. The next carries 183. From the outside those are separate casinos with separate names, separate artwork and separate advertising; from the register they are one licence, one company and one set of terms, filed on one page.
Nothing on a casino's own site is designed to tell you this. The licensee name is required in the footer and it is there — in small grey type, usually a company name you have never heard of, next to an account number that means nothing without looking it up. Reading three of those footers gives you three company names. The connection only appears when you read thirty, and nobody reads thirty.
02 When one address is declared by two companies
It happens more than you would expect, and this tool shows it rather than resolving it for you. Across the register, 121 addresses are declared by more than one licensed business. Some are a group holding a separate licence for betting and another for gaming on the same site — bet365.com is declared by Hillside (UK Sports) and by Hillside (UK Gaming), and both are correct. Others are a brand that changed hands while the previous holder's declaration stayed on file.
Picking one and printing it would be tidier and would sometimes be wrong, so the tool names every company that matches and lets you see that there are two. Where the answer is genuinely ambiguous, the ambiguity is the answer.
03 What the answer is actually good for
Knowing the company behind a brand changes three practical things. Your terms and conditions are the company's, not the brand's, so two casinos on one licence usually share wagering rules, verification requirements and withdrawal limits. Your complaint goes to the company's dispute service, not the brand's, so opening a second account with a sister brand after a bad experience takes you back to the same desk. And your accounts are not spread the way the four different logos suggest.
None of that makes a shared licence a warning. Large licensed groups are the normal shape of this market, and a company running twelve brands is not doing anything it should not. It is simply a different picture from the one the brands present, and it is the one fact you cannot get from the casino itself.
What this can and cannot tell you
The index behind this tool is every domain declared to the Gambling Commission by every licensed business in Great Britain — 2,135 web addresses across 604 companies, read from the public register on 31st July 2026. All 2,664 licensees were checked; the rest declared no domain.
A “not found” is not proof that a casino is unlicensed. It means no licensed British business has declared that address. That is strong evidence and it is not proof: the register lists what operators declared, so a new or undeclared address can be missing from it. It may also be a page rather than a site. The tool names what it cannot rule out rather than guessing.
Questions about this tool
4 answers
01 Why can the Gambling Commission's own register not answer this?
It can, if you already know the answer. Its search matches the names of licensed businesses, so it answers "what does Jumpman Gaming Limited run?" and cannot answer "who runs Barz Casino?" — which is the question a player actually has. This runs the register's own domain lists backwards, from the address to the company.
02 What does it mean when nothing is found?
That the address is not among the domains any licensed British business has declared. That is strong evidence and it is not proof: a site licensed but recently launched, a page rather than the declared address, and an operator with no British licence all look identical from here. The tool names all three rather than choosing the most dramatic one.
03 Why does one address sometimes return two companies?
Because 121 addresses in the register are declared by more than one licensed business. Some are a group holding separate betting and gaming licences on the same site — bet365.com is declared by Hillside (UK Sports) and Hillside (UK Gaming), and both are correct. The tool shows both rather than picking one.
04 Does anything I type leave my browser?
No. The index loads once as a static file and the search runs on your device. There is no server to send a query to, and the site runs no analytics at all.
