Mr Green Sister Sites
The short answer
Mr Green is operated by Blue Rock Managed Services Limited on Gambling Commission account 67740. No other UK brand currently runs on that licence account.
Every brand on licence 67740
No other brand currently sits on this licence account.
How the group is structured
Mr Green is the only trading name on account 67740. In licensing terms it stands alone: there is no sibling brand sharing its operator, and no group-wide account policy that could reach it from somewhere else.
Is Mr Green safe?
Mr Green holds a current Gambling Commission licence under account 67740. That is the part you can verify yourself, and it is the part that matters: a UK licence brings segregated customer funds, a named alternative dispute resolution route, mandatory age verification and GAMSTOP participation.
What a licence does not tell you is how the operator behaves — how fast withdrawals clear, how it handles a disputed bonus, how heavy the verification is. That is worth reading reviews for. What we publish here is the record, not a score.
To check it yourself: open the Gambling Commission public register, search Blue Rock Managed Services Limited, and confirm account 67740 lists Mr Green as a trading name. It takes about thirty seconds and it is the only source that cannot be marketed at you.
GAMSTOP and self-exclusion
Because Mr Green is licensed by the Gambling Commission, a GAMSTOP self-exclusion blocks it. It also blocks every other brand on account 67740 and every other UK-licensed gambling site, in one registration.
This is the reason the "sister site" question matters to people who have self-excluded. You cannot get round GAMSTOP by moving to a sibling brand, and any site advertising itself as outside GAMSTOP is not UK-licensed. We do not list those, and we do not link to them.

Questions about Mr Green
How many sister sites does Mr Green have?
None. Mr Green is the only trading name on account 67740.
Who owns Mr Green?
Mr Green is operated by Blue Rock Managed Services Limited. The licensee is listed on Gambling Commission account 67740.
Is Mr Green licensed in the UK?
Yes — account 67740 on the Gambling Commission register. We recheck every account on this site monthly; this one was last confirmed in September 2026.
Does GAMSTOP cover Mr Green and its sister sites?
Yes. One GAMSTOP registration blocks Mr Green, plus every other UK-licensed site.
Can I claim the welcome bonus at Mr Green and its sister sites?
Usually not. Operators normally write the welcome offer as one per customer across the whole licence, so claiming at several brands on account 67740 tends to breach the bonus terms rather than double your money.
If my account is closed at Mr Green, can I use a sister site?
Often not. Account decisions are made by the licensee, not the brand, so a closure or restriction on account 67740 is commonly applied across every brand on it.
