Which UK Casinos Are Sister Sites? Full Owner & Licence Table
Every row names the company holding the licence, not the brand on the shirt sponsorship. That company is the legal entity holding your money. Online casino sister sites take two shapes. Some groups build and run everything in house, so one company owns the brands, the software and the licence. Others rent that stack out, and the name on the site stops matching the register. A white label casino works that way. The Jumpman Gaming sites alone cover over a hundred domains on one account.
Only a UKGC licence makes an operator legal for British players, and every entity below holds one. Other regulators are not automatically weaker. An MGA licence protects a player about as well, while permits from Curacao or Anjouan are a thinner baseline with a slower complaints route.
Where the register and a footer disagree, the row reads Unknown rather than a guess. Register checked on 17 August 2026.

Sister Sites, White-Label Brands and Shared Licences Are Three Different Things
Three separate relationships get flattened into one phrase. The difference decides your welcome offer eligibility, whether verification carries over, and whether an exclusion follows you.
So what are sister sites, stripped of the marketing? Brands linked to the one you use through a shared owner, a shared technology stack or a shared licence. The link is a corporate fact, not a promise about the product.
Same owner
Brands under one parent company inherit the corporate spine and little more. LC International Limited runs Ladbrokes alongside Coral on account 54743, and both carry near identical terms, the same payment set and the same support structure. The part you see does not carry across. Lobbies and promotions differ, and the accounts stay separate, which is why a good offer at one brand tells you nothing about the other. A casino group that size usually holds several licences at once.
Same white-label provider
People mistake this one for common ownership more than any other. An independent company rents the technology, the payments and often the licence itself, then markets its own brand on top for a fee.
White Hat Gaming Limited runs that model on account 52894, with roughly 25 domains flagged white label. Casimba is one. The brand belongs to Casimba Gaming, yet the footer names White Hat Gaming Limited as operator. White Hat Gaming casinos share a cashier and a complaints route while their brand owners stay separate. A white label casino proves nothing by its design.
ProgressPlay Limited runs a comparable estate on 39335, with over a hundred partner brands on one shared licence.
Same UKGC licence number
Here is the only definitive test. Two brands under one UKGC account number are legally the same licensee, whatever the branding suggests.
The consequence lands on your account. Measures applied to the licensee, restrictions and exclusions included, reach every brand it runs. Flutter shows the reverse: Paddy Power and Betfair sit on PPB Entertainment Limited, account 39426, while the Sky brands run on Bonne Terre Gaming Limited, 065519. One owner, two licensees, two perimeters.
How to Check If Two Casinos Are Sister Sites Yourself
Anyone can run this check in five minutes, and it beats every ownership claim on an affiliate page, ours included. The register also catches a change of hands. Search Casushi and two companies come back: Dazzletag Entertainment Limited on 39358, Solaya Group Limited on 100050. The brands moved to Solaya on 1 April 2026, so the older number is history rather than a contradiction.
One limit before you trust the method: it proves who holds the licence, not who owns the brand. Four steps:
Find the legal entity in the footer, which UK-licensed sites must display with the licence number
Look that entity up in the Gambling Commission public register and note its account number
Compare both account numbers, because matching numbers mean one licensee
Where the entities differ, compare the terms wording and the lobby template
What Sister Sites Mean for Your Welcome Bonus
The real reason most people look up the sister sites of a casino is a second welcome offer. The answer starts with a rule change. Since 19 January 2026 every UKGC licensee caps bonus wagering at ten times the bonus, and one offer can no longer span two products, so a football bet cannot unlock casino spins.
That reset the maths. A £10 bonus once carried £500 of play-through at 50x, and the ceiling now sits at £100. Game weighting survived the change, so a slot counting at 10% still stretches the real wagering requirement well past the headline.
Eligibility is the part nobody publishes clearly. Some groups treat each brand as a separate acquisition, so Ladbrokes pays a new customer and Coral pays the same person again. Others apply one bonus per network: join Sky Vegas and the Sky Bet offer may already be spent. That rule sits in the bonus terms rather than the headline.
Opening several accounts to claim one offer twice counts as bonus abuse, and operators confiscate the winnings once the details match. Terms below were read on 17 August 2026.
| Operator | One offer per brand or per network? | Where it is stated |
|---|---|---|
| Jumpman Gaming Limited | Per brand | Bonus terms |

Self-Exclusion and Deposit Limits Across a Casino Network
GAMSTOP covers everything. Register once and every UKGC-licensed site blocks you for six months, a year or five. No sibling brand gets you around it.
An operator block is narrower, and this is where people get caught out. Excluding yourself at one brand normally covers every brand on that account number, so a block at PlayOJO reaches the whole SkillOnNet estate. It stops at the licence boundary. Self-exclude from Sky Vegas and Tombola stays open.
A deposit limit reaches less far still. Operators set them per brand, so a £50 weekly cap on one site does nothing to restrain spend on its sibling the same evening. That is the most important practical warning here, and a GAMSTOP self exclusion is the only network-wide self-exclusion closing that gap. If gambling stops feeling like entertainment, help is free:

GAMSTOP handles the block itself
Shared Progressive Jackpots Inside a Casino Group
A progressive jackpot pool rarely belongs to the casino. It belongs to the game studio, and every venue running that title feeds one pot. Mega Moolah and Jackpot King both work this way, which explains why the counter reads the same at two brands with nothing else in common.
Inside one casino group the effect gets amplified, since a large network pushes more players through the same titles and the pool climbs faster.
Now the honest part. A shared pool means the same prize, not better odds, and moving between sibling brands does nothing for your chance of triggering it. The trigger sits in the game, not the wrapper.
Sister Sites vs Independent Casinos
Both models answer to the same regulator, so the choice is about product rather than protection.
Readers searching for an online casino with no sister sites want a single-brand licensee, and those exist. Tombola is one. It holds its own licence and builds its games in house. Independent casinos UK players can trust pass the same test as everything else here: open the register entry and count the trading names. One brand, no siblings.
| Network brand | Independent single-brand casino |
|---|---|
| Vetted operator with a long licence history | Shorter track record to check |
| Familiar payments and consistent standards | Distinct product, often sharper promotions |
| Lobbies repeat across the group | Fewer payment options in most cases |
| Offers may be capped across the group | Own welcome offer with nothing to share |
| Exclusions can cascade between brands | Exclusion covers one brand only |
Closed and Rebranded UK Sister Sites
Networks shrink as well as grow, and 2026 has been a heavy year for brand closure. A site that quietly stops taking deposits is the first sign.
If a brand closes while you hold a balance, the money is still yours. Contact the licensee. Use the payment method already on the account, because most orderly closures pay out that way. If the operator stalls, escalate to its named dispute resolution service, free at every UKGC licensee. If the licensee has gone, the Gambling Commission takes over.
Segregation ratings decide what that balance is worth in an insolvency. At the medium level, where most operators sit, customer money is separated from company funds but not ring-fenced. At the basic level there is no protection at all, and segregated player funds become another line in the administration. Check for a dormant balance too. Some brands deduct a monthly fee after a year of inactivity.
| Brand | Operator | What happened | Date | Where players moved |
|---|---|---|---|---|
| mFortune, PocketWin, Mr Spin, Dr Slot, Cashmo | In Touch Games Limited | Licence surrendered, sites closed | 5 September 2023 | Balances returned to registered methods |
| Luckland, SpinShake, Cashiopeia | AG Communications Limited | Closed | 31 December 2025 | None |
| Jaak Casino, PlayLuck, TopTally | AG Communications Limited | Closed | January 2026 | None |
| Hot7Casino, 24Spin, CasinoLuck | AG Communications Limited | Closed | February 2026 | None |
| Karamba, Griffon Casino | Aspire Global network | Moved to another licensee | 2026 | White Hat Gaming Limited |
| Yako Casino | L&L Europe Ltd | Closed | 30 September 2025 | Other brands on 38758 |
| No Bonus Casino, Race Casino | L&L Europe Ltd | Closed | 1 June 2026 | Other brands on 38758 |
| Mr Green | Mr Green Limited | UK licence surrendered | 28 October 2024 | Closed to UK players |
| Casushi, Fruit Kings, Peachy Games | Dazzletag Entertainment Limited | Rebrand of the licensee | 1 April 2026 | Solaya Group Limited |
Withdrawal Behaviour Across Sister Sites
Sibling brands usually pay at a similar speed, for a structural reason. The same payment stack and KYC team sit behind them, so when one holds a withdrawal for a manual check, the others follow.
No measured payout time figures appear here yet, because advertised speeds are marketing and repeating them would add nothing. Until our own tests are done, check these per brand:
- the pending period applied before a withdrawal is processed
- the minimum and maximum per transaction
- the payment methods, since e-wallet support differs by brand
- whether a fee applies to your chosen method
How We Verify Ownership and Rate Sister Sites
Every ownership claim here rests on two sources that agree: the legal entity in the brand footer, and the matching entry in the Gambling Commission public register.
We publish a claim only when the entity and the account number match. Where they disagree, the row reads Unknown until one of the sources is corrected. Re-checks run quarterly, and after any announced sale or closure.
The site earns commission from some operators listed here. That does not affect the table order, which follows licence data.
