Grosvenor Casinos: an independent reference
Grosvenor Casinos is the largest casino chain in Great Britain: 53 venues in towns and cities across the country, plus an online arm, all owned by The Rank Group and licensed by the Gambling Commission. That combination — a physical estate first, a website second — makes it behave differently from the online-only brands most guide sites cover. This page explains what the chain actually is, who regulates it, and where the published facts end and our guesswork would begin. We have no commercial relationship with Grosvenor, hold no account with them, and have not visited a venue; everything below is sourced from public records and is dated so you can judge how stale it is.
This is an independent reference site. It is not operated by, endorsed by or connected to Grosvenor Casinos or The Rank Group. There are no registration links on this site.

What the estate contains
Live table games
Roulette, blackjack and poker dealt by staff on a supervised floor.
Electronic machines
Gaming machines sit alongside the tables under separate regulatory limits.
Tournament poker
The chain runs a national tournament circuit rather than one-off events.
An online arm
A separate product with its own licence conditions, covered on its own page.
The four pages worth your time
Each one covers a question people put into a search box, and each one stops where the public record stops.
How to check a claim about this brand yourself
- Find the operating company name, not just the trading name — for Grosvenor that means looking for The Rank Group.
- Look the operator up on the Gambling Commission's public register and read the licence status there.
- Check the date on any revenue, customer or venue-count figure before you repeat it; a lot of what circulates is from 2014.
- For anything about a specific building — hours, games, dress code — go to the operator's page for that venue, not to a guide site.
- If a page quotes a bonus amount or a payout time without a date attached, treat it as unverified until you see it on the operator's own terms page.
Regulator and safer-gambling schemes referenced on this site
We reference these because they are public bodies or national schemes anyone can verify. Listing them is not an endorsement of any operator, and none of them endorse this site.
Reference articles
Background pieces on how licensed British casinos actually run — regulation, floor procedure, supervision and the safer-gambling machinery that sits behind all of it. These are written to stay true as offers and interfaces change, and new pieces are added on a fixed schedule rather than in bursts.
- The house edge
Where the house edge comes from, why betting systems redistribute risk rather than remove it, and what that means for how you set a budget.
- Live dealer
How live-dealer casino games are produced, why latency is designed in, and what the format does and does not change about the odds.
- Machine categories
Why two machines that look identical can have different limits, how categories work, and what a return-to-player figure does not tell you.
- Source of funds
What triggers a source-of-funds enquiry at a licensed operator, why it usually appears at withdrawal, and how to tell a normal check from a stalling tactic.
- Age and identity
Why licensed operators must verify identity before play rather than at withdrawal, and what that means for the documents you are asked for.
- Self-exclusion
Why online and venue self-exclusion are separate processes, what GAMSTOP covers, and why the schemes are deliberately hard to reverse.
- Roulette variants
Live, electronic and hybrid roulette — including the Pinball Roulette machines introduced in 2012 — and what actually differs beneath the presentation.
- Surveillance
How table surveillance works, what top-hatting is, and the software this chain installed in 2011 to detect late bets automatically.
Four things worth knowing before you read anything else
Most pages about this brand are written by affiliates who have never set foot in one of the buildings. We have not either — the difference is that we say so, and we stick to what is on the public record. Here is the record.
- 🏛️
A chain, not a website
Grosvenor operates 53 casinos across Great Britain and two unbranded sister venues in Belgium. The company head office is in Maidenhead. It began life as County Clubs, became Grosvenor Clubs, and took the Grosvenor Casinos name in January 1969.
- 🧾
Owned by a listed parent
The chain belongs to The Rank Group, which also runs bingo and online gambling businesses in Belgium, Spain and the UK. That matters when you read financial claims: the numbers you find are usually group-level, not venue-level.
- ⚖️
Regulated by the Gambling Commission
Both the venues and the online product operate under Gambling Commission licences. That regulator sets the rules on age checks, self-exclusion, advertising and source-of-funds enquiries — not the operator, and not us.
- 📅
The big numbers are old
The figures quoted everywhere — £391.2m revenue, £56.8m operating profit, 1.7 million customers, 8.5 million visits — are from the year to June 2014. They are real, they are also more than a decade old. Treat them as history, not as a description of the business today.

Questions people actually ask
- How many Grosvenor casinos are there in the UK?
- Fifty-three, spread across major towns and cities in Great Britain, with two unbranded sister casinos in Belgium. The estate reached that size largely through a single transaction: the takeover of 19 Gala Coral casinos completed on 12 May 2013, which made Grosvenor the largest casino network in the country. An earlier version of that deal, covering 23 venues, stalled in 2012 after a Competition Commission and Office of Fair Trading decision, and four casinos were removed before the revised deal went through.
- Who owns Grosvenor Casinos?
- The Rank Group. Rank operates casino, bingo and online gambling businesses across Belgium, Spain and the UK, so Grosvenor is one division inside a larger listed group rather than a standalone company. This is worth knowing when you read financial or customer-number claims about "Grosvenor" — many of them are group figures.
- Is Grosvenor licensed?
- Yes. Grosvenor is licensed and regulated by the UK Gambling Commission. That licence is what obliges the operator to run age verification, offer deposit limits and time-outs, participate in the national self-exclusion arrangements, and make source-of-funds enquiries when required. If you want to confirm a licence yourself, the Gambling Commission maintains a public register of licensed operators — check it there rather than taking any guide site, including this one, at its word.
- Does this site take deposits or open accounts?
- No. This site has no registration links, no deposit forms and no affiliate tracking to a casino. It exists to summarise publicly recorded facts about the chain and to be honest about which facts we have not checked. Anything involving your money or your identity should happen on the operator's own site, under their terms.
- Why does this site not list opening hours for each casino?
- Because we have not verified them. Opening hours, table minimums and which games a particular building offers change, and the operator's own site is the only place those are authoritative. Publishing 53 pages of unverified detail would make this site look more useful while making it less reliable — that is a trade we are not willing to make.
