We’ll see if Grosvenor’s approach holds up for UK players, or if you’d be better off elsewhere.

Brand’s History and Ownership
Rank Interactive brought Grosvenor Casino to the internet in 2007, but this brand began decades earlier. Back in the 1970s, Grosvenor opened its first real casino and today, these casinos occupy prime spots in British cities.
The casino’s current form took shape in 2013 when Rank Group expanded. Already running Mecca Bingo successfully, Rank purchased Gala Casinos and developed the Grosvenor One program which combined both online and real casino gaming. Grosvenor membership rewards offer standard perks – nothing too huge, only basic benefits for regular players.
Anyone familiar with Rank Group’s other online casinos will notice similarities in the website design. Mecca Casino and several sister sites share the same basic template – similar menus, game layouts, and account features. But Grosvenor adds extra value through two major differences. They included a poker section and sportsbook while most of its siblings lacked these and added some deals exclusive to them only, it skips bingo rooms entirely though.
The casino has kept a clean record and never had any regulatory issues, it isn’t in any blacklists either.

About the Company Behind Grosvenor Casino
Grosvenor really does a decent job at running an online casino alongside their physical casinos, and even connects them in some way. That said, it’d be even better if Rank Group added more unique flairs to their casinos, Grosvenor included.

License and Security points
*The ratio of total casinos evaluated according to scores 1-5
Grosvenor operates under UKGC license 57924, which is basically a seal of approval from the UK government that lets Grosvenor run all sorts of betting services: from regular casino games to sports betting and even virtual events. For players outside Britain, the casino also holds Gibraltar licenses RGL 133 and 134, so everyone gets the same level of protection.
Players worried about problem gambling will find help right at the bottom of any page on the site. There’s a button marked “Responsible Gambling” – click it and a menu pops out from the right side of the screen. This splits into two parts: Tools and Support. The Tools section puts players in control of their gambling habits. You can set up deposit limits, turn on Reality Checks or activate the Take a Break feature. For longer breaks, players can use Self-exclusion which completely locks the account.
The casino recently introduced a feature called Player Protection. This system keeps track of how people play and step in before small problems turn for the worse. If someone starts to bet in a different manner than usual, the system notices. Instead of just shutting down the account, it will stop sending promotional offers until the pattern goes back to normal. The casino even explains what they look for on their ‘markers of harm’ page.
Grosvenor also links directly to major UK gambling support groups which provide more professional help than even the best casino agents could offer. They also suggest using GAMSTOP if you want to block access to all UK gambling sites at once. They also are very strict on minor protection, Grosvenor weeds accounts under 18 out and suggests parents use tools like CYBERsitter and Net Nanny for keeping kids away from gambling content. The casino website uses SSL encryption, but sadly there’s: no two-factor authentication for accounts, a small oversight on their part.

Security Aspects at Grosvenor Casino
Grosvenor has great license coverage with UKGC and Gib licenses on board, responsible gambling features are all here and that ‘Player Protection’ tool further strengthens the prevention of risky behaviour.
Initial Thoughts
Grosvenor’s site uses dark blue and green colours with white backgrounds that make long sessions at the tables much easier on the eyes. At the top of the home page, there are shortcuts for main casino sectors live dealer games, sports betting, online slots, poker rooms, jackpots, and table games. You can find the support options and membership details right there too. Now, while everything is clearly labelled and the navigation is easy, we really didn’t like these giant black bars occupying the screen. Would be much better with them gone.
The games come organised in a slim menu bar across the screen. New players see a sign up bonus right on the homepage, with popular games shown below. As you scroll down the page, you will see plenty of ads for their real casinos, no surprise since that’s where they started. Each game section has its own help guide at the bottom. The footer makes it easy to find important stuff, and I like how they put their responsible gambling tools right in the front.
The search box here is pretty versatile, it allows you to switch between the casino, sportsbook and even physical venue search bars. Sorting options here are poor though, you can access them in ‘All Games section’, there’s just an alphabetic or reverse alphabetic sorting and nothing else. The lack of a provider filter is a major upset.
Most game thumbnails have a small info button. When you press it, it shows you everything about the game: the rules, what RTP % is, pay lines, special features it includes, and the smallest bet allowed.
We had no issues with performance, pages load fast and games load and play with no issues. This applies to desktop and mobile alike.
| Navigation Bar | Combines main menu and subcategories, easy access to slots, poker, sports, and more. |
|---|---|
| Search Bar | Multi-use tool to search games, sports events, or offline casinos with quick switching options. |
| Game Info | Has info like RTP and pay lines, but not all include provider details. |
| Safer Gambling Tools | Clearly highlighted, offering deposit limits, reality checks, and self-exclusion. |
| Page Load Speed | Fast and responsive with minimal lag during testing. |
| Filtering Options | Basic filters are available but missing a provider filter for games. |
| Visual Design | Modern and clean, but blank edges waste space. |
Key Features of Grosvenor Casino
Grosvenor Casino feels much like other Rank Interactive casinos as they tend to keep their sites pretty similar. The site doesn’t need a complete makeover – just some minor updates to match what players expect from today’s online casinos, like an addition of a provider filter for instance.
