About UK Casino Sister Sites
A reference index of UK casino and bingo brands, organised by the Gambling Commission licence account each one trades under.
Why this exists
“Sister sites” is one of the most searched phrases in UK gambling and one of the worst served. Most pages answering it are lists assembled from other lists. The underlying fact — which company holds the licence, and what else is on it — is public, free and rarely cited. This site publishes that and little else.

What is in the index
483 UK casino, bingo and betting brands, each matched to a Gambling Commission licence account — 129 accounts held by 109 companies. 39 of those companies run more than one brand, and those are the licence families the site exists to document. Every brand page names the licensee, prints the account number, and lists the other trading names on it.
What this site is not
- Not a ranking site. There are no scores, no “top 10”, and no ordering that implies one licensed operator is better than another.
- Not a bonus comparison site. Offers appear on a brand page only where one has been read from the operator's own terms and dated, and they are never the reason a brand is listed.
- Not a route to unlicensed operators. Sites marketed as “not on GAMSTOP” are not indexed, not linked and not named. They are unlicensed for British customers, and the people searching that phrase are usually the people GAMSTOP was built for.
How it pays for itself
Some outbound links to licensed operators are commercial. They have no effect on which brands are indexed, what order they appear in, or what any page says — the index is generated from the register, so a brand cannot buy its way in or out of it. Licence facts are not for sale, and there is nothing on this site that a payment could change.
