UK online casinos to avoid
Not all online casinos are created equally, and knowing the difference is important. Our team is committed to highlighting what we believe to be the best online casinos, and also, which ones to avoid. Not all operators are reliable, and you don’t want to get caught short.
Learn how to spot illegally operating casinos and avoid ones with bad reviews. Don’t put yourself at risk of identity theft, fraud or other cybercrimes.
How we review online casinos – our criteria
Not all casino review sites are willing to share their workings, but we believe in putting you in control. We’re here to help you make your own decisions by highlighting the judgement criteria used by our industry experts.
Doing this keeps us transparent, and empowers you to rate your own casinos.
Generous bonus offers & promotions
We start by looking at the welcome bonuses and promos an operator offers. The best UK real money casino sites include generous bonuses to attract new players.
We like to see no-deposit bonuses and welcome offers that reward players for signing up without the need to make a deposit to give you a taste of what’s on offer before committing to your budget.
To score a high rating for UK casino bonuses, an online casino with a deposit bonus should offer as much as 100% matched bonus funds, at least £100's worth, with some free spins thrown in for good measure. The best can go up to £300, though that's rare. Mr Mega hits a good middle ground, with £150 in casino bonus funds + free spins.
Any sites offering low or no wagering requirements will also score well with our team. The UK average is around 35x. Magic Red offers a few no wagering bonus spins as part of the sign up package.
Wide variety of games and software providers
Of course, we’re all here for the entertainment, so we like operators that carry a lot of content from a good selection of iGaming providers, including top industry names and award-winning software suppliers like Pragmatic Play, Playtech, Evolution, Hacksaw Gaming and more.
When conducting casino reviews, we look to see which names are happy to associate with an operator; reputable providers won’t work with illegal or unsafe sites.
The scope of content is also important. We like to see a good range of video slots, table games, live dealer offerings and more. A content library with upwards of 1,000 titles will ensure there’s something for every type of player. Presently, PlayOJO is doing great here, with around 5,000. A casino can push the needle with scratch cards, bingo, and other rare offerings.
Our UK online slots page discusses the breadth of online casino content available to players in the UK and the award-winning providers behind the games.
10+ payment options with good cashier terms
We always look out for online casinos offering decent payment options, and the top reviews go to the ones offering at least 10 different banking options. There should be no transaction fees.
When analysing your payment options, we pay particular attention to amount restrictions, awarding high scores to operators with low minimum deposits (£5-£10), and high max withdrawal caps (around £10,000 at a time for a good score). Trusted payment methods like Skrill, Apple Pay, and certain debit cards show the casino is in good standing with financial institutions.
A site’s payment options can also indicate the operator’s legitimacy. Remember that it is illegal to use credit cards or crypto at online casinos in the UK, so if you see either as an option, it should be an immediate red flag.
Complete UKGC licensing & compliance with advanced security
Your security and the legitimacy of a site are paramount when reviewing online casinos. Local casinos in the UK must be fully licensed to operate legally, which is why we will only ever recommend casinos with full UKGC licensing and endorsement.
Part of the licensing requirements is to have the UKGC logo on the website with clearly marked links to the operator licence. Can't see a licence? Avoid.
Another essential for protecting players at online casinos is SSL encryption. Operators handle a lot of sensitive information to comply with this heavily regulated industry. KYC documents and banking info are just the start. You don’t want the risk of your data being leaked or your payment info stolen by cybercriminals, so look for SSL encryption.
Other top metrics to look out for include: links to third-party audits, by testers such as TST or eCOGRA, and responsible gambling tools, along with links to help organisations.
(Note: The UKGC and the Malta Gaming Authority have similar frameworks, so there is precedent for some MGA-licensed casinos to be allowed to operate in the UK. However, this is strictly scrutinised and only applicable in very specific cases. We'll point it out in the few cases where it's relevant. For the most part, these casinos will have a UKGC licence anyway.)
Mobile site & app experience
Responsive design should be a priority for all casino operators, with advanced HTML5 available for gamblers to play their favourite online casino games.
Our review process considers the availability of online casinos for mobile play and desktop computers, as it caters to the lifestyle of many UK casino players. Operators must offer fully functional mobile play, whether through mobile browsers or a native mobile app, in addition to desktop play.
Mobile-first casinos or those with dedicated mobile apps provide smooth and accessible play on the go without compromising quality. Apps aren't necessary to provide a good mobile experience, but they do help casinos rank highly. Advanced search tools, filters, and good navigation + load times help casinos edge out the competition.
Excellent customer support options
When it comes to online casino reviews in the UK, customer service is a massive factor in how we award ratings. You should be looking at availability for live chat; the best UK online casinos have round-the-clock agents, with fast response times of 1-3 minutes to be connected.
Most online casinos will offer several communication channels, such as email and live chat functionality, as well as online resources like a knowledge base and a detailed FAQ section.
Our team likes the human touch, so if you can get in touch with a real human being who can help with your query fast, and with a high-quality response, then the operator will score well for customer service. All British casino does well here, they proudly show off a UK-based support team, which is a sight above the external agencies used by many other operators.
Our team doesn't accept anything with less than a 24-hour response time for email; the best reviewed casinos can hit this benchmark, so neither you nor we should settle for anything less.
Fantastic user experience
When it comes to user experience, we’re looking for ease of navigation, how long it takes to sign up and claim the bonus, how easy it is to find the information you're looking for, access the games on offer, and quality of display.
If registration takes longer than two or three minutes, then we consider that too long. If an operator claims to have over 1,000 titles in its lobby, but you can’t find the table games, then that’s a navigation issue. And if you regularly have to relaunch a game or refresh the page to get your game working, there’s a risk you could miss out on a payout or lose interest in your gameplay.
With so much top-quality competition, a clunky or complex website will have us all jumping ship to a more user-friendly site. Cull all the dead weight and you don’t waste your time on a site that can’t provide the casino experience you want.

"Honestly, I didn't know it was so easy to check whether a casino is legal in England. Thanks for making it so clear. The bonuses at sites I tried were decent, I don't deposit more than ￡20 at a time but I won a few quid at a couple. Thanks for asking!"

Why should you read casino reviews?
Detailed online casino reviews present the key information.
Our team review is made of players and experts, and knows what matters the most to online players. They seek to deliver the insights you’re looking for, including the best online game libraries, top systems with reliable sites, and best bonus offers to help boost your win potential.
We make it a point to compare casinos, and to use real examples in our reviews. We're not afraid to call out an okay casino bonus if there's a better one a click away. By reading and learning from our expert reviews, we hope that you can achieve the following:
- Learn exactly how the operator’s bonus works, including the expected wagering requirements, validity periods, and how to avoid violating the terms and conditions of your bonus.
- Save yourself the trouble of delayed payments or issues with withdrawing funds. Ensure the operator caters to your payment needs. You don’t want to risk scoring a big win and being unable to withdraw your winnings.
- Avoid accidentally accessing dodgy or illegal sites where you could be at risk of fraud. You don’t want to give away your personal details to cybercriminals.
- Learn what to expect from the different types of games available and where to find the content that suits you best.
- Find reputable sites with top-quality customer service so you can get reliable and trustworthy assistance in a timely fashion when you need it.
How to do your own research and rate casinos for yourself
When it comes to finding the perfect online casino, do your own research. Follow these five steps, and they'll get you started. Investigate, compare, and dig deep into each option. Trust your instincts, and make sure our claims hold up under scrutiny. It's like being a detective in your own casino adventure.
- 1
Visit the casino and assess
Visit the online casino site and compare it against our seven unique assessment criteria. This is essential for determining if a casino is the right fit for you. Check out the selection of games on offer, how easy you find the site to navigate, if the games load and display well, and how easy it is to contact customer support.
- 2
Check licensing
Check for the UKGC logo and links to the casino operator licence. This is a critical step for all UK online casino players. As discussed above, all UK-based operators must have full UKGC licensing and show compliance with licence conditions. If you can’t find evidence of a licence, it’s best to take your business somewhere else.
- 3
Review the site’s safety and encryption
Before you consider entering your personal details or banking info on any website, always check the site’s security. This can be done in several ways, including viewing the URL to look for a padlock icon on Windows or opening up the two bars icon in the URL bar on Mac. You can also copy-paste the URL into a third-party SSL certificate checker website.
- 4
Check out user reviews
Compare player reviews from third-party sites like Trustpilot. We recommend you always check what other players have to say about a site and factor this into decision-making. If there’s nothing but negative reviews online or if you find repeat stories of players struggling with withdrawals, that’s definitely a red flag. (That being said, take some of it with a pinch of salt - the New York Times says only 1.5% of people leave reviews.)
- 5
Compare bonuses before signing up
Research and compare the welcome bonuses and promos on offer. Not all casino bonuses are the right fit for your needs, so it's worth knowing your options. Some players prefer no-deposit bonuses. Others always ask 'how long is the bonus valid for?'. Watch out for disconnects between the size of the bonus, its wagering requirement, and its expiration date. Hint: A 200x wagering requirement isn't exactly rare, but if it's on a £1,000 bonus that expires in 3 days, you probably won't have time to play through it.
How often do we update our online casino reviews?
We freshen up our reviews whenever there's a significant change that merits an update.
As a leader in the review space, we have one eye on our casinos, looking for updates, and we also follow news in the industry — mergers and acquisitions, rebrands, new deals with game studios, and more can all come up in the press. Because we're such an established brand, we often get casinos coming to us to inform us of updates too; they want the information we have on them to be up to date as well.
Some of the flags we look for as signals to update:
-
Bonus updates
Casinos are always mixing things up with new welcome bonuses, usually giving them a makeover every couple of months. This means the bonus value and terms can change, prompting us to spruce up the bonus section in our online casino reviews. They can swap between bonus types like deposit matches or free spins, tweak the wagering requirements, and update the expiration dates. Whenever there's a change, you can bet we'll be updating our reviews to keep you in the loop.
-
Big game changes
Casinos can add a few new slots every week. It's not worth anyone's time to update for every new slot. But we do library audits every month, and if something significant occurs, like a new studio partnership that brings in a whole host of new and exciting games, especially if they're famous titles, it makes sense to get an early update to our online casino ratings in.
-
Mergers and sales
When MGM resorts bought out LeoVegas in 2022, we had a lot of updates to make. Ownership changes mean different policies, new promotions and partners, and sometimes, dips or troughs in the general service quality. These require regular updates until the casino settles back into its normal rhythm.
-
Other external events
When new casino sites get people talking, it's usually because of some noteworthy developments. That means an update is needed. Sometimes it's good things, like awards, which are a feather in any casino's hat. Sometimes it's bad things, like disciplinary action, fines, or revocation of licenses. The latter means that all links to the casino from our site are killed. Chatter on Trustpilot, Quora, or Reddit can let us know when there's something new worth investigating at a casino.

UK casino review FAQs
Which online casino has the best reviews?
Currently, our experts rate Magic Red as the best online operator in the UK – offering an impressive welcome bonus. The free spins are a no-wager deal, which wins extra points.
Why should I trust Casino.org’s ratings?
Our rigorous 25-step online casino testing process ensures you can trust our casino reviews to deliver open, honest, and transparent feedback. Our reviews cover everything from exploring your payment options and software providers to checking UKGC licensing, site legitimacy, and how to contact customer service when you need support, among many other key factors.
Are your casino reviews up to date?
Yes, we regularly update our reviews to make sure you have the freshest and most relevant information. That being said, there are thousands of UK casinos, so if you spot a change before we do, contact us, and we'll prioritise the update.
Do you review untrustworthy online casinos?
Absolutely. We recognise that it’s just as important to draw your attention to illegitimate and untrustworthy online casino sites as it is to point out the best in the industry. This will help you make a better-informed decision when choosing the right operator for you and help you avoid nasty surprises.
What is the most trusted online casino?
Right now, we'd say Duelz. It's difficult to categorise a 'safest' when a lot of the licensing and auditing requirements are the same across the board, especially in a highly regulated market like the UK's. That being said, our internal data currently flags Duelz as the casino that pays out the most on average, which is a measurable criterion we're comfortable associating with a casino's trust level.
