UK Online Casino Reviews June 2025

There’s so much that goes into reviewing an online casino, like assessing the selection of games, making sure the deposit options are up to scratch, and checking that the site runs well on both desktop and mobile.

Our team of experts at Bookies.com put together comprehensive and balanced reviews, to help you choose a great gambling site. So you can sit back, relax, and browse our guide to the best online casino reviews in the UK.

Best Online Casino Reviews UK

Online casino sites are a dime a dozen in the UK. To be able to accept players, casino sites need to hold a special license from the UK Gambling Commission, which means that they’ve been approved in terms of specific factors like game fairness and data security. But there’s so much more that goes into making it to be one of our top rated online casinos than just a licence.

If you’re new to online casino gambling, or you’re simply looking to set up an account at a different casino site, you might start feeling a little overwhelmed when you’re presented with all the options. While a lot of UK gambling sites tend to function in a similar way (and might even have a similar look and feel), each of them will have its own pros and cons.

The exact casino site you choose will largely depend on you as a player. For example, while some people might prefer a bigger game selection, others are far more interested in the range of casino bonuses, and others still will want a perfect mobile experience. Our team are all experts in the online casino world, so we can really help you choose a gambling site that suits you.

So, how do we do it? We’ve put together a whole list of the best casino reviews for you, right here at Bookies.com. Whenever we review online casino sites, we look at some specific criteria. For example, it’s no use signing up at a site that only has a few slots or no new slot games, so we look at the variety in depth. We also ensure that the promos are attractive for both new and returning players, and that the terms and conditions aren’t too restrictive.

There are also lots of other smaller factors that we look at, which you might not even think are worth considering. But trust us, they are. For example, we make sure the customer service is up to scratch, that the site works flawlessly across all devices and browsers, and that there are more than enough secure and convenient payment methods for you to choose from.

Overall, we aim to bring you well-balanced UK online casino reviews, which cover the full gambling experience, and which can help you choose the perfect site. 

Online Casino Reviews – Casino Bonus Sites

Many online gamblers choose their next casino site based mainly on the types of bonuses for new accounts that are available. As a brand new player, you might be attracted by the lure of a big first deposit match, or maybe 200 free spins for selected games like Big Bass Bonanza, but sometimes that just isn’t enough. It’s also super important that online casino sites have generous promotions for existing players, so you’ll have lots of reasons to come back.

When you’re signing up at new casino sites, there’s only one surefire way to make sure you get that great bonus. And that’s by signing up through a link here at Bookies.com. Remember, if there’s a promo code needed, you might need to enter that when you’re signing up too (we’ll tell you more about promo codes a little later).

These are some of the main types of bonuses that we tend to see on the sites we review, and what we look out for when we’re assessing them.

Free Spins

There’s nothing more fun than spinning on your favourite slots totally for free. While lots of UK online casinos promise free spins no deposit bonuses, there are a few key things we always look for when we’re reviewing these offers.

For example, we make sure that the bonus spins are available on popular games, like Starburst and Big Bass Splash, and that the wagering requirements aren’t too high. Offers that have absolutely no wagering requirements are the best type of free spins bonus out there.

We also love to see free spins offers that come hand in hand with a deposit match bonus so that you can maximise your money even more. Netbet casino, Duelz casino, and LiveScoreBet casino are just a few of the best online slots sites that offer free spins.

No Deposit Bonus

A no deposit bonus is pretty much the best type of offer that online casino players could hope for. When you’ve just signed up at a new site, you might want to test out the games and overall experience without committing to spending any of your real money. A no deposit bonus gives you free casino credits or free spins to use on the site and to see if you like it before you deposit any cash. And who knows, you might just walk away with a nice little win.

When we review online casinos, no deposit bonuses are one of the first things we look for. But we know that the terms and conditions for no deposit offers are sometimes very strict, so they’re not always even worth claiming. We look at the value of the free spins or the online casino bonus money, as well as the wagering requirements, to make sure the offer is good enough for you.

Casino Bonus Codes

Some gambling sites require you to use a special code to be able to claim your offers, whether they're reload bonuses or free spins offers. As part of our casino reviews, we need to make sure you know how to find and use the code. For example, if you’re signing up at PricedUp casino or certain other sites on our UK online casinos list, you’ll need to use a special code. We usually include the code on our casino review page, or otherwise we might direct you to the casino’s promo page where you’ll be able to find it.

When we review casino bonus codes, we look at exactly when you need to enter the code (for example during registration or within the cashier section), and give you a step-by-step process to follow. It’s super important that you use the code exactly when you’re supposed to, and that you enter it exactly as it’s given to you, otherwise you won’t be able to claim the promo at all.

Cashback Bonuses

As a new player at an online casino, you might be wondering if there are any ways that you can mitigate some of the risks that come with gambling. Cashback is one ideal way to do this, so we always look for these offers when we’re doing our reviews of casino sites. A cashback casino bonus does exactly what it sounds like - it gives you a certain amount of your losses during the promo period back in the form of bonus cash or real money.

When we review cashback offers, we look for promos that give back at least 10% or 15% (rather than just 5%), up to at least £100. We’ll always give a casino a better rating if the money is awarded back as real cash rather than as a bonus with wagering requirements.

£10 Deposit

If you’re just starting out at an online casino site, you might not necessarily want to make a deposit of hundreds of pounds (unless you’re a real high roller, that is). That’s where £10 deposit offers come in. You don’t have to make a huge deposit to get the offer, and you’ll still be able to enjoy a casino bonus or some free spins, depending on the casino site. A few examples of £10 deposit casinos are Pub Casino, Fun Casino and 888 Casino.

While a £10 deposit casino bonus offer might seem like the dream for new customers, there are a few key things we look at when we’re writing an online casino review. For example, some sites may have very high wagering requirements on bonuses like this, while others limit the amount of money that you can actually win. It’s also important to remember that if you’re claiming a deposit match offer, you’ll usually only get an extra £10 if you deposit £10, even though the maximum welcome bonus could be in the hundreds.

For all casino bonuses, it's extremely important you double check the conditions before signing up. Based on your personal preferences and the way you like to play, something that appears to be the best bonus might not be for you, so always check any £5 minimum deposit casino site.

Casino Reviews – Payment Methods

Making a deposit at your online casino of choice is the first step towards starting to play slots, live dealer table games and other casino favourites. So it’s absolutely essential that all UK gambling sites offer payment methods that are secure, easy to use, and ideally they shouldn’t charge any fees.

When we review online casino payment methods, we always look for the main banking options like debit cards, trusted e-wallets like PayPal casino, Klarna casino, casino Neosurf, AstroPay casino deposits, ecoPayz casino withdrawals and Skrill casino payments, prepaid options like paysafecard and mobile-first deposit options like Google Pay and Apple Pay. Credit card payments like Amex casinos aren't allowed in the UK.

Fast Withdrawal

Getting your winnings will probably be your priority at an online casino site, so one of the main things we look at in our online casino reviews is how fast the withdrawals are. Some casino sites take several days to process any withdrawal requests, so you could be sitting around for quite a while waiting for your cash. We always give a site bonus points if they are a fast withdrawal casino, especially if they process payouts instantly.

PayPal

As one of the most trustworthy e-wallet providers in the world, it should be no surprise that lots of UK online casinos accept it. When we review gambling sites, PayPal is definitely near the top of the list of payment methods we like to see as it is available at £1 deposit casino sites and £3 minimum deposit casino sites.

We check the minimum and maximum payment amounts, make sure there aren’t any steep fees for using PayPal, and check what the withdrawal timelines are like. The best online casinos in the UK process your withdrawal requests within a matter of hours (rather than days), and thereafter PayPal withdrawals should reflect in your account pretty much immediately.

Apple Pay

If you’re using mobile casino apps or websites on your iOS device, you might prefer to deposit using Apple Pay on your phone. Casinos with Apple Pay are some of the most convenient mobile-first payment methods, as they allow you to add money to your account with just a few clicks - you won’t need to input your bank card details every time, but the money comes straight from your bank account, so you also don’t need to deal with third-party apps or accounts.

Deposit By Phone

Deposit by phone bill casino payments aren't available at most online casinos just yet, but they’re getting there. This is a quick and convenient way to add money to your online casino account using the bill on your mobile phone. The only problem? You can’t use it to withdraw. So when we do casino reviews, we need to make sure that the sites we recommend have lots of other options for you, like bank transfers.

Google Pay

Android users rejoice! Lots of the online casino sites that we review allow you to use Google Pay for deposits and withdrawals. Just like Apple Pay, Google Pay casino payments are available from your mobile device and allow you to make secure transactions without needing to enter your bank card details every time. We look for sites that offer quick Google Pay withdrawals and no fees.

Trustly

Many online casino players prefer to use a bank transfer over other methods, but the payout speed is a major negative. Trustly is a great way to move money from your bank account to your online casino account, without the waiting time. Although Trustly casinos aren't hugely common in the UK, we tend to look out for it more than for bank transfers.

Visa

Visa is one of the most popular bank cards in the UK, and the good news is that almost all trusted online casinos allow you to use it for both deposits and withdrawals. When we review a casino site, we look for fast Visa withdrawals, so that you can get your money within a matter of hours rather than several days, which is the norm with debit card payments. This usually applies to Revolut casino payments too.

Top online casinos also don’t charge any fees for bank card withdrawals, and they have a wide range of minimum and maximum deposit and withdrawal amounts to suit all players.

Skrill

Skrill is a convenient e-wallet that allows you to keep your money for online gambling separate from your main account, which is why a lot of people prefer it over bank cards. There’s just one thing to be careful of when you’re choosing Skrill casino payments when you sign up - sometimes you can’t use it to claim bonuses. We already check the welcome bonus terms and conditions to see whether or not this payment method is accepted for offers, and we’ll let you know in our review of the casino site.

Paysafecard

If you want to control your spend with a prepaid solution, rather than using your main bank card, paysafecard is ideal for you. While not all UK gambling sites accept paysafecard just yet, we’re starting to see it become more and more common, and it’s definitely something we look out for. Unfortunately, it's not possible to make paysafecard casino withdrawals, so when we’re reviewing an online casino, we also need to make sure that other methods like bank transfers are available, so that you can get your winnings as quickly as possible.

Neteller

Neteller is an e-wallet, just like Skrill and PayPal casino UK options, but this one is really aimed at online gaming, so it’s a method we always look for when we do online casino reviews. Many casino sites don’t allow you to use Neteller to claim bonuses, so we’re more likely to recommend sites that don’t have that restriction. We look for sites that process Neteller casino withdrawals immediately, plus the fees should either be non-existent, or very small.

MuchBetter

MuchBetter is a mobile wallet that works via an app, so if an online casino has a great mobile website or downloadable app, we expect to see MuchBetter casino deposits as a valid payment method. We also check if casino sites accept prepaid cards, as MuchBetter is really starting to revolutionise online payments via its prepaid Mastercard, which allows you to top up by a certain amount of money, which is kept separate from your main bank account.

Mastercard

Just like Visa, Mastercard is one of the key payment methods of choice for players in the UK. It’s very unlikely that we’d recommend an online casino that doesn’t allow Mastercard payments. Mastercard is a super safe and convenient way to deposit at online casino sites, and we look for low minimum deposit and withdrawal amounts, and no fees. Mastercard casino withdrawals usually take a few days to reflect in your account, so we prefer to see sites where withdrawals are available within hours.

Bank Transfer

A bank transfer is a bit of a last resort when it comes to online casino deposits and withdrawals, but it’s still good to see it accepted at top casinos. The main reason why we wouldn’t usually recommend bank transfer casino payments is because it takes a lot longer than the other methods. For example, you might be waiting up to five or even seven days before the money reaches your account (for both deposits and withdrawals).

Even though bank transfers take a long time, they’re a very safe way to transact, and if you use certain deposit methods like paysafecard, which don’t allow withdrawals, you’ll need to use one anyway. When we’re reviewing online casinos, we make sure that bank transfer payments don’t charge big fees even at £20 minimum deposit casino sites, and that the minimum withdrawal amount isn’t in the hundreds.

Online Casino Reviews UK – Casino Games

Games are the main reason why any player signs up at an online casino site. Casino games are a whole lot of fun, plus they offer chances to win real money, so it’s hugely important for any gambling site to offer top quality slots, live dealer games, virtual table games, and bingo.

There are literally thousands of different game options out there, and as a player you won’t want to trawl through endless lobbies to make sure the games you’re looking for are available before you sign up. When we write casino reviews, we spend a lot of time assessing the games. Which providers make the games? What’s the Return to Player (RTP) percentage like on each game? Do the games come with special features? We answer all of these questions and more when we review online casinos.

Slots

One of the main things we look at as part of our casino site reviews is the range of slot games. After all, slots are the main reason most people sign up at online gambling sites. When we review slots, we first look at the number of games, and the providers. We prefer to see sites where there are at least 1,000 slots, but some can have as many as 5,000, with the selection growing all the time. We love the range of slot games at a few specific UK casino sites like BetMGM UK and 888 Casino.

There are a few games we like to see in every lobby, for example some of the UK’s favourite games from top software providers in the online gambling industry like Starburst by NetEnt, and the Big Bass series by Pragmatic Play. We’re always on the lookout for progressive jackpots at the best online slots sites (we love to see Mega Moolah games in the lobby), and we look at game RTP to make sure there are some high payout options. It’s ideal when casino sites have the slots broken down into handy categories, for example Megaways games, or slots with features like Hold & Win or cascading reels.

Slingo

Not all casino sites double up as slingo sites, but it’s slowly becoming something we look for when we do our reviews. We’d recommend Fun Casino, which has an entire section dedicated to slingo games.

Slingo is an exciting mix of bingo and slots, and you can often find themed versions at the best UK online casinos. We make sure that the slingo games come from world-leading providers, and that the themes appeal to all different types of players. Plus, we test a selection of the slingo options to make sure that the gameplay is smooth across all devices, and that you’ll have a real chance to win.

Roulette

Roulette is such a casino classic, so as soon as we start reviewing any online casino site, we always head straight to the table games section to make sure it’s available. You might be able to play roulette in a virtual format where the computer acts as the dealer, or in a live casino environment alongside a real dealer.

We look for a whole lot more than just a few basic games like European Roulette and American Roulette. We make sure that the site has innovative games like Lighting Roulette, fast-paced games like Auto Roulette, and even tables where you can play in a whole array of different languages like German, Turkish, and Finnish.

Blackjack

If you can perfect your basic blackjack strategy, you might just be able to bag yourself a win. No online casino site is complete without at least a few variations of the classic, strategic game. Most sites have both RNG virtual and live dealer online blackjack real money games, and some sites even have unique versions of the game like Lighting Blackjack and Speed Blackjack.

The other thing we assess is the stake limits at blackjack tables. While it’s good to see sites that have low minimum bets of around £1 or £5, we’re always impressed to see special tables for high rollers. Here you might be able to bet up to £1,500 a go, and at some casino sites you could even take your seat alone with a dealer, at one of the exclusive Salon Prive tables.

Baccarat

Baccarat is beloved at online casino sites thanks to its simplicity. Unlike some other card games like blackjack and poker, baccarat is entirely based on luck, so we always consider it to be one of the best games to play if you’re just getting started at gambling sites. Luckily, lots of UK online casinos offer baccarat, usually within their live casino section.

From thrilling games like live online Baccarat Squeeze, where you can feel the tension building as the cards are revealed, to games like Lighting Baccarat, which come with multipliers to add to your win, there are tons of ways to enjoy the game. Just like when we review other card games, we look at the number of tables, range of betting limits, and the quality of the dealers as part of our casino reviews.

Live Dealer

Live dealer games are a staple of gambling sites, so all of our online casinos reviews take a good look into the classic games and the casino live bonus. We look for tables from major live casino providers like Evolution Gaming and Pragmatic Play Live, but we also like to see a variety of games from smaller studios. We particularly like the live casino at LiveScoreBet, which features exclusive, branded tables.

When we write an online casino review, we always play a selection of the games, so that we can ensure the video streaming quality is top-quality, and that the dealers are absolute professionals. We like to see games with a wide range of stake sizes, to appeal to both newer and more experienced players. We understand that live casino sites should cover more than the basics like blackjack and roulette, so we look for more innovative games like Lightning or Mega Fire Blaze versions, as well as unique gameshows. 

Bingo

The UK absolutely loves bingo, so we always count it as a major win when we see bingo rooms at an online casino. In fact, one of the first things we do during a casino review is to check the bingo offering.

Only the very best UK bingo sites have interactive rooms, where you can play alongside other real people, and you can even chat with your fellow players and the cool chat hosts who might just award you with free promos. And speaking of promos, we make sure that online casino sites know how to reward bingo players with special bonuses like free play or a deposit bonus. If you’re keen to try out some live bingo, Lottoland casino is a great place to do it.

Even if a casino site doesn’t have a live bingo offering, we often see virtual bingo games, where you can play alone with the computer, for a more relaxed experience.

Scratchcards & Instant Win

If you’re looking for a break from the complexities of slots and table games, scratch cards and instant win games are a great option. Not all UK online casinos have them, but we often see them in games lobbies anyway - one great place to try out the best online scratch cards is at Mr Vegas casino.

These casual games are based just on luck, so they’re ideal for newer players - but don’t worry, we test them out for you to make sure they really do offer actual chances to win. When we’re reviewing scratch card games, we like to see a diverse range of themes, and it’s even better when the games are based on some of your favourite slots, for example Rainbow Riches or Fishin’ Frenzy.

Casinos Reviews UK – What Else We Look For

While bonuses, games, and payment methods are the main factors that make a great online casino, our online casino reviews for the UK go into a whole lot more depth. There are some smaller things that can have a huge impact on your overall experience such as customer support, and the availability of a mobile app.

Customer Service

No matter how easy a site on our online casino list is to use, there’s always a chance that you might need some help from the support team at some point in your journey. When we’re reviewing an online casino, we always test the customer support options, to make sure they’re easily accessible, and that the support agents are friendly and knowledgeable.

We look for casino sites that offer support via multiple channels including live chat, email, phone, and social media, and we always give casinos a higher rating if the team is available 24/7.

Easy to Use Online Casino Site

Whether you’re a newbie or a pro, you’ll probably be most interested in the actual gaming experience, so the last thing you want is a complex or non-user friendly experience. When we do any UK casino reviews, we always check the sites on both desktop and mobile, to look for a smooth navigation, comprehensive filtering options, in the games lobby, and smooth play.

Ideally, the site should be optimised for all devices and browsers, so you can play in a way that suits you. Casino sites will certainly lose points from us if they look dated, or if they make it difficult for you to access essential areas, like your account section and the promotions page.

Casino App

As we mentioned, Bookies.com casino reviews always take the mobile experience into account. More and more people in the UK prefer to play on the go, so it’s absolutely essential that casino sites cater for mobile players. While an app isn’t a necessity, it’s always nice to have, as apps can really enhance the gameplay experience on iOS and Android mobile devices.

We like to see casino apps that carry the full range of games, and which allow you to use all the features of the site such as claiming welcome bonus offers. If a casino site doesn’t have an app, we might still give them a high rating, but only if their browser-based mobile site is absolutely flawless.

Security

There’s one thing you can be absolutely assured of - all the UK casinos we review on Bookies.com are fully licensed by the UK Gambling Commission. This stamp of approval means they’ve met the body’s strict standards when it comes to security and general safe gambling at a secure online casino. But we still put the best casino apps through their paces when we review them.

We look for security features like SSL encryption technology, strong data protection policies, and trustworthy payment methods like the ones we mentioned earlier on this page. We also look for certificates from third parties like eCogra, to ensure that all of the real money games are tested and audited for fair play.

Reputation

Assessing a brand’s reputation is a key part of our internet casino reviews. When we're looking at reputable sites, our team already has the background on the casinos, and knows exactly what the customers think. But when we review newer or small sites in the online casino industry, we need to dig a little deeper. We read other reviews, for example on the App Store or Play Store, as well as customer review sites, to see what people are saying. It's important not to look past reported issues for the sake of the best online casino bonuses in the UK.

If we see any major red flags, such as people complaining about unhelpful customer support, data breaches, or difficulty getting paid out, we’ll make sure to investigate during the course of our review, so you'll know if you're playing at a reputable online casino.

Online Gambling Reviews

Even though you might specifically be an online casino fan, there’s no reason why you shouldn’t branch out into other forms of gambling like sports betting. The great news is that lots of UK online casino sites have a sportsbook section attached, so you won’t need to go very far to start wagering on major events.

Here at Bookies.com, we’re not just experts in casino gambling. In fact, as our name suggests, we’re also experts in betting sites. So if you like our casino reviews, you might just want to check out our reviews of all the best betting sites in the UK.

When we review betting sites, we look at similar criteria to online casinos, as a starting point. The most important factor for us is to make sure that a betting site is fully licensed, exactly like a casino would be. Once we’re sure that a gambling site offers a safe experience, then we can move on to looking at other things, like payment methods, bonuses, and desktop and mobile user experience.

The one area where our sports betting site reviews differ from casino reviews is where we look at the range of options to gamble on. While when we’re reviewing casino sites, we always look at the best payout slots and live dealer games as a priority, betting sites need to have a wide range of sports and markets for you to wager on. We look for all of the UK’s favourite sports like football, horse racing, tennis, and golf, but we also like to see more niche sports, as well as e-sports.

When we’re reviewing a betting site, we also pay close attention to the specific features like how the betslip functions on desktop and mobile, and whether the site has any special features such as cash out or a bet builder.

Just like when we write online casino reviews, our reviews of betting sites are balanced, so you can get a really good idea of whether or not a site is worth your time. Remember, when you sign up via a link on this page, we’ll make sure that you get a great bonus (like a free bet), so that you can kick off on a good note.
