UK casino sister sitesWhich casinos are secretly the same company?
Casino sister sites — sister casinos, if you prefer — share an operator and a Gambling Commission licence account. We read those accounts off the public register and list the online casino sister sites of every UK brand in full — no guesswork, no affiliate ranking dressed up as research.
Different brands.

Most-checked brands
The brands people look up most. Open one to see every other site on the same licence.
“Is it legit?” — check the licence
The question people actually type. A UK site is legitimate when a current Gambling Commission licence account carries its trading name — a public fact you can check in a minute, not an opinion. Here is what the register says about the brands asked about most.
A licence means the operator answers to the Gambling Commission for funds protection, age and identity checks, complaints routing and advertising rules. It does not mean the games pay well, support is quick or withdrawals are fast — those are separate questions, and no licence answers them. We publish no scores and rank nothing.
How to check a licence yourself
Everything on this site comes from one free public source. Here is the whole method, so you never have to take our word for it.
Find the licensee
Scroll to the casino's footer. Look past the brand name for the company that holds the licence —
usually written as Operated by … Limited with an account number beside it.
Look it up on the register
Search that company on the Gambling Commission's public register. It is free, it is the legal record, and it takes about thirty seconds.
Read the trading names
Every trading name listed against the account is a sister site. One name means the brand stands alone. A list means you have found a group.
Who owns your casino?
Most UK brands are trading names, not companies. The licensee is the company that holds the account, takes the deposit and appears on your statement — and it usually runs several other sites you would never connect to it.
Who owns what
One company can run a dozen brands that look unrelated. These are the operator groups behind the UK market, with the licence accounts they trade under.

The market at a glance
How concentrated UK gambling really is. Each tile is one licensee, sized by the number of brands it runs.
The biggest licence families
The groups with the most UK brands on one account, named in full. If you have played at one of these, you have almost certainly played at a sister without knowing.
That name on your bank statement
A deposit shows the licensee's legal name, not the site you played at — which is why an unfamiliar company turns up on a statement. These are the names behind the biggest groups.

Common questions
The things people ask most about sister sites, answered straight.
What are casino sister sites?
Sister sites are gambling brands run by the same company on the same Gambling Commission licence account. They usually look like separate businesses, with different names, art and welcome offers, but one licensee is accountable for all of them.
How can I tell if two casinos are sister sites?
Check the licensee named in each site's footer, then look that company up on the Gambling Commission public register. If the same account number carries both trading names, they are sister sites. That is exactly how every page on this site is built.
Does one account ban apply to all sister sites?
Not automatically, but it often does in practice. Operators share verification and risk flags across the brands on a licence, so a closure or restriction at one brand can follow you to the others. A standalone licensee has no group to carry it to.
Can I claim the welcome bonus at every sister site?
Usually not. Most operators run one welcome offer per customer across the whole group, and the terms say so. Claiming at several brands on one licence is what bonus-abuse rules are written for.
Does GAMSTOP cover sister sites?
Yes. GAMSTOP applies to every operator licensed by the Gambling Commission, so one self-exclusion blocks every brand on every UK licence at the same time — sister sites included.
