Question 1

What exactly are sister sites in the context of UK online casinos?

Accepted Answer

Sister sites are online casino or betting platforms that are owned by the same parent company — often a Ltd registered in the UK or Gibraltar — or that operate under the same UKGC gambling licence. Because they share ownership, they typically run on the same software infrastructure, use the same payment processing systems, and are subject to the same responsible gambling policies. From a player's perspective, connected brands often look and function similarly, though they may carry different branding, themes, and promotional offers. BeGambleAware advises players to be aware of how many brands within a single operator group they are active on, as the net effect on your spending can be significant.

Question 2

Can I claim a welcome bonus on affiliated brands if I've already registered on one?

Accepted Answer

In most cases, no. Operators typically restrict welcome bonuses to players who are new to their entire network, not just a single brand. If you've already registered on one casino within an operator's portfolio, you are usually ineligible for the new player offer — regardless of the bonus amount advertised. The exact policy varies by operator, so always read the terms and conditions carefully before you visit and register, specifically looking for clauses that reference existing customers of affiliated brands. Check whether free spins are credited immediately or whether the bonus amount is released only after a qualifying deposit.

Question 3

Does self-exclusion through GamStop cover all connected brands?

Accepted Answer

Yes — if you register with GamStop, the UK's national self-exclusion scheme, your exclusion should apply to all UKGC-licensed gambling platforms, including connected brands within the same operator network. However, if you self-exclude directly through a specific casino's customer support rather than using GamStop, the exclusion may only apply to that individual brand and not automatically extend to affiliated platforms. For comprehensive protection, GamStop is always the recommended route. BeGambleAware also provides a directory of support organisations if you need additional help managing your gambling activity.

Question 4

How can I find out which casinos are connected to one another?

Accepted Answer

The most reliable method is to check the UK Gambling Commission's public register, where you can search for an operator's company name — including their Ltd or org registration number — and see all brands registered under their licence. Additionally, reading the terms and conditions or footer of any casino you visit will reveal the operating company name, which you can then cross-reference. The min deposit page and payment method section often look identical across connected brands, which is another useful indicator. Affiliate research tools that publish verified operator-to-brand mappings can also save time.

Question 5

Are connected casino brands always identical in terms of game selection?

Accepted Answer

Not always. While connected brands share the same underlying platform and supplier relationships, individual brands within a network often have slightly different game libraries, unique loyalty schemes, and distinct visual themes. Operators frequently differentiate their brands to cater to different player preferences. One brand might emphasise live dealer games with a higher min deposit threshold, while another might focus on classic slots with a lower barrier to entry. The net wager requirement on bonus offers can also differ between brands in the same network, so always check the specific terms when you visit each platform individually.

Question 6

Are there any advantages to playing across multiple brands from the same operator?

Accepted Answer

There can be, provided you manage it carefully. If you have already verified your identity with one brand, the process is often faster on affiliated platforms since KYC systems are frequently shared. Some operators run promotions specific to individual brands, meaning a bonus amount credited exclusively to one platform in the network can represent genuine extra value. However, you should keep a count of your total net spend across all platforms and be mindful that wager requirements and the number of days before a bonus expires may differ. BeGambleAware recommends setting deposit limits individually on each platform you use, since these are not automatically synchronised across connected brands.
