Casino Sister Sites: Same Owner, Licence or Platform?

Image: Gambling Commission

Casino sister sites can mean brands operated by one licensed company, companies within one ownership group, or sites using similar software. Those relationships are different. For a player checking who holds an account, the licensed legal entity and exact domain are the best starting points. A recognisable lobby or matching promotions cannot replace that check.

Our comparison below was checked on 13 October 2026 against Gambling Commission records and Sky's own disclosure. It deliberately covers a few named brands rather than an enormous list with untraceable connections. Where we have not established ultimate ownership or platform supply, we say so. A licence register can identify a responsible operator without answering every question about shareholders, technology or a contractual relationship between businesses.

Ask 'same licensee?' when you want to identify the company responsible for gambling offered through the site. Match the company name, account number, active activity and consumer domain in the public register. Ask 'same ownership group?' when investigating a corporate connection. That needs current company filings or official group disclosures, not a guess based on brand spelling.

Ask 'same platform?' when investigating the technology supplying the account screens, games integration or back office. That needs an attributable supplier or operator statement. Similar pages can result from a template, contractor or widely sold product. Even a confirmed supplier relationship does not establish that the supplier holds your money, sets every promotion or owns the brand. A useful sister-site entry should name the relationship it proves and cite evidence for that exact relationship.

Brillbet and Stakewise have different licensees in the checked records. UK Digital Bookmakers Ltd holds account 101570, while Rocbrook Limited holds 100802. Sky's casino brands provide a separate example of several consumer domains under one company, Bonne Terre Gaming Limited, account 65519. This is a comparison of licensed operation, not a complete ownership tree.

Do not turn the first two rows into a claim that no corporate relationship could exist. They prove separate licensed entities. We have not verified a common ultimate owner or platform supplier for Brillbet and Stakewise, so neither relationship is asserted here.

Brillbet's active trading-name entry sits under UK Digital Bookmakers Ltd. The company's summary shows active remote casino and real-event betting activities from 15 June 2026. Stakewise's record sits under Rocbrook Limited, whose active casino, real-event betting and virtual-event betting activities date from 13 April 2026. Those dates describe the records' listed permissions; they are not proof of a brand's first public launch day.

For a practical comparison, write the two company names and account numbers side by side before studying logos. If both pages advertise a familiar game studio, that shows a game-brand connection rather than common ownership. If both use the same button layout, the layout answers no licensing question at all. Read our Brillbet review and updated Stakewise review for brand-specific limitations, including where current service evidence remains incomplete.

Sky's official help separates its products: casino, bingo and poker are operated by Bonne Terre Gaming Limited, while sports betting and virtual racing are carried out by SBG Sports Limited, account 67370. The disclosure also says Sky trademarks are owned by Sky Limited and used under licence. A trademark owner and gambling operator therefore need not be the same company.

A customer researching 'Sky sister sites' should identify the product involved rather than treating the familiar name as one legal answer. A complaint about a casino transaction and a question about sports betting may require different company details. The older Bonne Terre Limited record, account 38718, is also surrendered, which does not establish that today's Sky Vegas brand closed. Our Sky licence-change case study links the historical and current records without inventing a transfer date.

A hypothetical group can operate Brand A and Brand B with different eligible games, bonus deadlines or complaint contacts. Finding a corporate connection would not answer those questions. Copy the conditions of the exact offer and the exact account you are using. Do not assume a promotion seen at one brand is available at a related brand or that a previous verification decision transfers automatically.

The same caution applies to consumer-funds protection. A group name does not establish the protection category disclosed by the legal entity holding a balance. Our customer-funds guide explains the difference between licensing and insolvency arrangements. Compare the actual disclosure rather than labelling an entire group safe because one site describes a particular trust or segregated account.

For self-exclusion, read the operator's stated scope and any wider scheme's conditions. A sister-site list is not a way to find another route around an exclusion or an account restriction.

Record six fields for a brand: consumer domain, product, legal operator, UKGC account, evidence URL and check date. Add ultimate owner and platform only as separately sourced fields. This structure makes a later licence change visible without rewriting a vague assertion that two brands are connected.

1. Read the site footer and terms for the product being used.
2. Match the legal entity to the regulator's active permission.
3. Match the exact address to the domain list.
4. Check official filings before adding a group-ownership claim.
5. Require a supplier disclosure before adding a platform claim.
6. Leave unanswered fields explicitly unknown and recheck when sources change.

A hypothetical card reading 'Brand A, Company X, account 12345, platform unknown' is more useful than one reading 'sister of Brand B' with no explanation. It tells the reader which fact is established and which question still needs investigation. A record checked today can become historical evidence after an operator transfer.

This comparison identifies licensed entities and selected registered brand or domain connections at a stated date. It does not score payout reliability, make a deposit recommendation or rank companies by ownership alone. Those judgements would need evidence about current terms and service as well as the licensing identity.

If another list calls two sites sisters, ask whether it means a shared licence, a shared parent or a shared platform. The answer should come with a current source. For a suspicious mismatch, use our step-by-step licence check before sharing details. Keep the named relationships precise: two different licensees can resemble each other, and several products bearing one brand can be operated by different legal companies.

What are casino sister sites?

The phrase usually describes related brands, but it has no single precise licensing meaning. It can refer to one licensee, a shared corporate parent or similar software. State which relationship is meant and verify it separately. A visual resemblance or an affiliate list alone is not proof of who operates an account.

Are Brillbet and Stakewise operated by the same company?

The checked Commission records name different licensees: UK Digital Bookmakers Ltd for Brillbet and Rocbrook Limited for Stakewise. This establishes separate licensed entities, not the absence of every possible corporate connection. We have not verified a shared ultimate owner or software-platform supplier, so we make neither claim.

Do casino sister sites have identical withdrawal rules?

Do not assume they do. Read the exact brand's current payment and withdrawal terms, the legal entity holding the account and its complaints procedure. A shared owner or confirmed platform cannot establish identical cashier limits, verification requirements or processing performance. Keep a dated copy of terms applying to your own transaction.

Are Sky Vegas and Sky Bet operated by the same licensee?

Sky's current disclosure separates casino, bingo and poker under Bonne Terre Gaming Limited, account 65519, from sports betting and virtual racing under SBG Sports Limited, account 67370. A familiar Sky name therefore does not settle the operator for every product. Identify the product and legal entity before using a register entry.
