Greatbet Sister Sites
The short answer
Greatbet is operated by GR8ODDS Limited on Gambling Commission account 21483. No other UK brand currently runs on that licence account.
Every brand on licence 21483
No other brand currently sits on this licence account.
How the group is structured
Greatbet is the only trading name on account 21483. 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 Greatbet safe?
Greatbet holds a current Gambling Commission licence under account 21483. 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 GR8ODDS Limited, and confirm account 21483 lists Greatbet 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 Greatbet is licensed by the Gambling Commission, a GAMSTOP self-exclusion blocks it. It also blocks every other brand on account 21483 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 Greatbet
Is this a Greatbet review?
Not in the usual sense. There is no score, no star rating and no ranking here, because we hold no data that would justify one. What this page is: the Gambling Commission licence record for Greatbet, every other brand on the same account, and how to verify all of it yourself in about a minute. If you want an opinion on whether the games pay or the support is quick, read an actual review site — and check this page first to see which other brands that opinion quietly also applies to.
How many sister sites does Greatbet have?
None. Greatbet is the only trading name on account 21483.
Who owns Greatbet?
Greatbet is operated by GR8ODDS Limited. The licensee is listed on Gambling Commission account 21483.
Is Greatbet licensed in the UK?
Yes — account 21483 on the Gambling Commission register. We recheck every account on this site monthly; this one was last confirmed in September 2026.
Does GAMSTOP cover Greatbet and its sister sites?
Yes. One GAMSTOP registration blocks Greatbet, plus every other UK-licensed site.
Can I claim the welcome bonus at Greatbet 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 21483 tends to breach the bonus terms rather than double your money.
If my account is closed at Greatbet, 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 21483 is commonly applied across every brand on it.
