Best Safe Online Casino Sites June 2025

Secure Online Casinos Trusted by Experts

There are tons of trusted online casinos out there, and sometimes it’s easy to spot the dodgy ones. Other times, that isn’t the case. Here at Bookies.com, we know exactly what to look for when it comes to safe online casinos - from proper licensing, to fair games.

When you’re choosing new casino sites, it’s always a good idea to consider what bonuses are available for new players. A welcome bonus is the best possible way for you to get started at a safe online casino. You’ll be able to use your deposit match or free spins to start playing some of the casino online games, and you might just bag yourself a win, without having to spend a huge amount of money at £5 deposit casino apps.

The best way to make sure you get the online casino bonus you deserve is to sign up for your account via a link here at Bookies.com. If you need a promo code to claim the offer, we’ll be sure to give that to you as well.

Best Safe Online Casino Sites

It was a challenge to whittle the hundreds of safe online casinos in the UK down to a list of only 10, but we think we’ve done a pretty good job. Here, we’re going to tell you a bit about each of our top 10 secure gambling sites, and what bonuses you can claim when you sign up with the best casino apps.

Mr Vegas

There’s a 100% welcome bonus up to £200 plus 11 bonus spins awaiting you at Mr Vegas casino. There are no wagering requirements on those spins, so any winnings are yours to withdraw immediately. Just make sure that you deposit at least £10 to avail of the casino bonus.

We were impressed to see that alongside all of the top games like Starburst and Gates of Olympus, NetBet also plays host to some exclusive games that you won’t find elsewhere, like NetBet Story of Odin, and Book of NetBet. There are even live casino bonus offers from time to time.

888Casino

The 888Casino welcome bonus is even more generous than most of the others on our list. While most casinos hand out a 100% match bonus, 888 gives you 100% up to a maximum of £200, so you know you're getting a great online casino bonus when you sign up with such a big name in the industry. 

When you’re playing at 888Casino, you’ll definitely want to try some of the seven figure jackpots like Mad Max Fury Road or The Goonies.

We were also impressed to see a wide range of live dealer games and tables where you can play roulette, blackjack and baccarat.

The welcome offer at Betano is quite unique - you’ll need to sign up, deposit and wager at least £10 on slots and then you’ll get a £25 bonus plus 25 free spins to use on Eye Of Horus.

We recommend having a go at some of the Rapid Fire Jackpots like 7’s Deluxe and Bigger Catch, or making your way to the live casino where you can play games like roulette, baccarat and poker. With games from providers such NetEnt, Play’n GO, and Amatic, there’s plenty to look forward to.

Plus there’s top-quality customer support, and lots of convenient casino payment methods.

Trustworthy and Safe Online Casinos UK

Each of our safe online casinos has its own unique features, for example while some are great for bonuses, others have a bigger range of games. We’ve put together a table of each site’s best feature, to help you decide which of our top online casinos is your perfect fit.

Best Secure Online Casinos

When we review secure online casinos sites, we look at a whole lot of different factors. Once we’ve established that the site is a licensed, safe place to play, we also need to make sure that it offers a great experience when it comes to the games and overall user experience.

Here’s what we look for at the best online slots sites:

Generous Welcome Offer

The best secure online casino sites give new players something extra special. For example, you might get a deposit match, 50 free spins, or cashback. We look for a big offer (up to at least £100 in matched bonus cash, or at least 100 free spins), but we also consider the terms and conditions. The best promos have lower wagering requirements, high win limits, and a good amount of time to use your offer.

Ongoing Existing Customer Offers

Once you find a safe casino that you like, you’ll come back again and again. For that reason, it’s important for sites to reward regulars just as much as newbies. We look for a great calendar of promotions (bonus points for different offers every week), including matched bonuses, free spins, cashback casino payments, and slots tournaments.

VIP Scheme

We’re always pleased to see a safe casino that rewards high rollers at £20 deposit casino sites. We like to see tiered loyalty schemes, where you can earn points to work your way up the levels, and get yourself even better bonuses. The best safe casinos also offer extra perks to VIPs. For example, you might get higher withdrawal limits and access to a personal account manager with some Apple Pay casinos.

Customer Support

Easily accessible and helpful customer support is one of the biggest marks of a safe online casino site. We like to see a range of different support options, from live chat, email, and phone to social media. Some PayPal casinos have team members on standby 24/7 to assist with queries.

We also like to see a comprehensive FAQs section or help centre where you can find all the information about topics like data protection and payment security.

Lots of Casino Games

We’re always impressed when we see a well-stocked games lobby, with at least 1,000 titles. The best safe casinos don’t just have slots, but also live casino games, classic table games, and sometimes even bingo.

We always look for independent certification that the games use Random Number Generator technology, so we can be totally sure they’re fair, and that you’ll have a real chance of winning. Those that do easily make our UK online casinos list.

Easy to Use Online Casino Site

Safe casino sites are always super easy to use. We look for navigation features that make it easy to find your way around the games lobbies and to areas like your account section and promotions page with just a few clicks.

Our online casino reviews will only highlight those operators with proper responsible gambling information available, promotion terms, and the help section front and centre, so you’ll know exactly where to go if you have any queries or concerns.

Real Money Casino App

Not all safe casinos have an online casino real money mobile app, but we’re always pleased to see one that does. We look into the app experience on both iOS and Android, and check the App Store and Play Store for any negative reviews, especially about the safety of the site. If sites don't have casino apps, we look for a fully optimised mobile website.

Licensed Operator

To operate legally in the UK, all legitimate pay by phone bill casino sites need to have a license from the UK Gambling Commission. This is the first thing we check when we’re reviewing gambling sites. We’ll never recommend a UK online casino to you if it isn’t appropriately licensed, as this is the best indicator that the site is totally safe and secure.

Casino Software Providers

All legitimate online casinos offer slots, table games, and live dealer games from well known software providers. There are certain names we always look for in the games lobbies, because we know these providers make totally fair games.

For example, some of the top online casino game studios include NetEnt, Pragmatic Play, and Games Global for online slots, and Evolution Gaming for live dealer tables.

Payment Methods

Reputable payment methods are an absolute must at any secure casino. The best sites allow you to choose between multiple options like bank cards, e-wallets, prepaid options, and even crypto. We always ensure that the payment pages are totally secure, and that the site uses encryption technology and firewalls, so that there’s no risk of your financial details being intercepted. There are growing number of new payment method casino options, such as Google Pay casino, Mastercard casino, Paysafe casino, Skrill casino, Trustly casino, Neosurf casino and Klarna casino options and many more.

Safety & Security

Safety is one of the most important factors when it comes to choosing good new online casinos. First, we look for a UKGC license, and then we explore other security features like encryption and firewalls, plus we check the data protection policy. Finally, we ensure that games use Random Number Generator technology to ensure games are fair.

Comparing the Safest Online Gambling Sites

While it’s important that best online casino sites offer a good mobile experience and plenty of games, there are definitely some factors we consider to be more important than others.

Security and licensing is critical. We only ever recommend licensed sites, and we always look in-depth at security features like encryption and firewalls. We also make sure that the payments are totally secure at £10 deposit casino sites, for example by looking for the lock icon in the URL bar on secure pages. Finally, we check if the site has a certification for game fairness, such as by an independent body like iTechLabs.

Once we’re happy that the site offers a safe and secure experience, we’ll move on to evaluating the other factors to see if the site is good enough to make it onto our list of the best safe casinos.

Licensed UK Casinos

In order for a casino to be licensed, it needs to meet a whole lot of strict criteria. For example, the site needs to prove that the games are fair, the payment methods are secure, and that there are certain protections in place for players. When you play at licensed casino sites, you can be sure that if you get lucky enough to have a win, you’ll definitely get paid out, with the fast withdrawal casino sites always worth looking out for.

When you choose an online casino from our list at Bookies.com, you can be absolutely certain that it’s fair and safe. We’ve done all of the research to ensure that we’re happy with the licensing and level of security at the site.

Secure Online Casino Bonuses & Promotions

The best safe online casino sites want to ensure players have a great experience, so they usually have some exciting bonuses for both new and returning players. These are the kinds of offers you can look forward to when you sign up at one of the sites on our list.

Deposit Bonuses

If you’ve signed up at any safe casinos online before, you’ll probably have heard of a deposit match bonus. These offers award a certain percentage of your deposit as bonus cash into your casino account, and you can use it on a selection of games of your choice.

The best deposit bonuses at safe online casinos usually award 100% of your first deposit up to several hundred pounds. Some casinos even give you multiple bonuses across your first three or four deposits when using casino bonus codes on sign up. Just like all casino offers, deposit match bonuses come with terms and conditions like wagering requirements and time limits. There often needs to be a minimum deposit to qualify for such bonuses, therefore while £1 deposit casino sites are great after the welcome bonus has been had, you may need to deposit more initially to get the offer.

No Deposit Bonuses

It might sound too good to be true, but some safe casinos will give you a bonus before you even deposit. No deposit bonus casino offers can come in the form of free spins, or casino bonus cash, to use on games of your choice.

Free spins no deposit offers are an ideal way for you to test out the online casino experience, to see if you like it before you spend any of your own money. The one thing to keep in mind is that even though no deposit bonuses do give you the chance to win real money, the terms and conditions that come with them can be very strict, so it’s important to understand them before you claim the offer.

Free Spins

The beauty of free spins offers is that they can help you discover new and popular games that you might not have played if you were using your own real money. Plus, you’ll have the chance to bag a win if you get lucky. Free spins promos might require a deposit, or you might get them totally for free.

Some safe online casinos even have tiered offers, where you can deposit more to get more free spins, or come back each day to get a new offer. Free spins aren’t just for newbies though - regulars might be eligible for them as often as every week.

Free Chips

If you’re a keen live casino fan, there’s nothing better than a free chips offer. But you won’t find them at all safe online casinos. While most sites concentrate on free spins or deposit match offers for slots fans, a select few of them actually reward live casino players.

If you do find a free chips offer, it’s a good idea to snap it up immediately. You might have to make a deposit to get your free chips, or they might be awarded as soon as you sign up, and you can use them to play all of your favourite casino games like roulette and blackjack.

Reload Bonuses

Reload bonuses are similar to deposit match offers, but they’re given to returning players to help boost their balance. Some safe casinos even hand out reloads as often as every single week, so you’ll always be able to come back and maximise your cash.

Just like deposit bonus match offers, reloads are usually available to be used on the vast majority of games on the site, and you’ll just need to make sure you meet the wagering requirements before you can withdraw. The good news is the wagering tends to be lower on reloads than on welcome offers.

Other Online Casino Bonuses

Safe online gambling sites offer all kinds of exciting offers for players who keep coming back. Be sure to check out the promotions section whenever you log in, to see what’s available. For example, you might be able to take part in slots tournaments where you’ll wager on selected games to work your way up a leaderboard and win prizes, or you could enter prize draws for bonuses and even tech gadgets.

Many sites also have VIP and loyalty programs, where you can earn points through your play and move up different levels towards even better bonuses and other special perks.

Safe Online Casino Games

Safe online casinos have so much more than just slots. These are some of the most popular types of games you might find at gambling online sites. And don’t worry - each of these games has its own features that makes it totally fair.

Blackjack

Most safe online casinos have multiple different versions of blackjack to try, and if you can master the strategy, you might just be able to bag yourself a big win with the likes of Pub casino.

Online blackjack UK is just as fair as playing in person because Random Number Generators shuffle the virtual cards, so you can be assured that the games aren’t rigged in any way. We’d recommend Betano casino as a great place to play Blackjack.

Roulette

Online roulette for real money is hugely popular at legit online casinos, so you can expect to see versions like European Roulette and American roulette, as well as unique and interactive games in the live casino. If you’re playing virtual roulette, the game is totally fair, even though the ball isn’t spinning around a physical table.

Computer algorithms determine exactly where the ball will land. Mr Vegas has a particularly excellent selection of roulette tables.

Slots

There are thousands of slot games out there, and one of the best selections you’ll find is at bet365 live casino. From big progressive jackpots, to games that come with all sorts of special features like Megaways, progressive jackpots, and free spins rounds, gameplay is always super exciting.

The best payout slots UK customers can sign up with use Random Number Generator technology, which means that sophisticated algorithms determine the symbols that land on the grid every time you spin, and everyone has the same chance of winning. People who likes slots, are also increasingly getting involved in slingo sites as the game is a fun combination of both slots and bingo.

Live Dealer Games

Live dealer games come in all shapes and sizes - from casino classics like blackjack and roulette, to immersive gameshows like Monopoly Live with Monopoly casino. Live casino games are available at almost all secure casinos, for example BetMGM UK.

When you play at live casino sites, you can rest assured that they’re totally fair, because you can observe the real dealer shuffling and dealing the cards, or spinning the wheel.

Baccarat

Live online baccarat is simpler than some other casino card games like poker or blackjack, but it’s just as fun - and most importantly just as fair. Many UK casino sites have multiple baccarat games in the live casino, where you can watch the real dealers via a video stream. You can also try virtual baccarat, which uses Random Number Generators, just like other casino games.

Video Poker

Playing video poker at safe online casinos like bwin is no different to playing in person. Video poker uses Random Number Generators, so it’s not rigged in any way. In fact, video poker often has a higher Return to Player percentage than other games at a £3 minimum deposit casino, so you might even have a better chance of winning.

Craps

By now you probably know what we’re going to say - craps is fair because it uses Random Number Generators. While it’s not one of the most popular games at UK online casinos, you might see a First Person version in the lobby, where animation combines with the live dealer experience.

Some casinos, like 888, also have an Evolution Gaming live dealer craps table, where you can watch the host throw the dice in real time.

Bingo

Although the gameplay experience is more interactive, online bingo sites like NetBet work in the same way as slots and other casino games - and that’s using Random Number Generators.

Each number has the exact same chance of coming up when you play, so you never know whether or not you’ll get lucky. The Random Number Generators act like the ball machine if you were playing in person at a bingo hall.

How to Sign Up to Safe Online Casinos

Signing up at a safe casino will only take you a few moments, so you’ll be ready to start playing before you know it. The process is very simple, and there are safeguards along the way to make sure that the casino can verify your age and identity.

Your starting point should be this page here at Bookies.com. You can choose your ideal casino from our list of UK casinos online, and rest assured that they’re all totally safe and secure. Click on one of our links to go off to your chosen casino and create your account.

The next step is to enter some basic details like your name, address, date of birth, email address, and mobile phone number. At this point, the best UK online casinos will attempt to verify your account automatically. This is usually done almost instantly, and then you’ll be ready to go off and make your first deposit.

In cases where your account can’t be verified using the automated systems, you’ll need to provide copies of documents like your ID and proof of address before you can play. It’s important to sign up using your correct, legal details to avoid any delays.

One of the best things about signing up at a new safe online casino is that you’ll be able to claim an exciting welcome bonus. Some sites require a special promo code to be entered either when you’re signing up or when you’re making your first deposit. If you do need casino promo codes to get the offer, we’ll be sure to list it for you on this page.

Banking Methods At Secure Online Casino Sites

The vast majority of players in the UK prefer to deposit and withdraw at online casinos using their bank card (debit cards only, Amex casino credit cards are not accepted) with Visa online casino payments, but there are also lots of other methods you can use.

Many sites accept e-wallets like Skrill, which have some definite advantages over bank cards. For example, withdrawals to e-wallet accounts tend to be much quicker (a matter of minutes rather than days), and they offer a more anonymous way of transacting. On the other hand, you’ll first need to set up and fund a third-party account before you can use it at safe online casinos, so in that way bank cards are a lot more convenient, even if the likes of MuchBetter casino, Revolut casino, AstroPay casino, and ecoPayz casino options are becoming more popular.

Some safe online gambling sites also accept payments via prepaid methods like paysafecard. This is a great way to control your spending and ensures that your personal details can never be compromised. The only downside is that you can’t withdraw using prepaid cards, so you’ll need to choose another method, such as a bank transfer casino option.

If you’re playing at safe online casinos on your mobile, you might want to make use of mobile-specific payment methods like Google Pay or Apple Pay. These are linked to your bank account, so they offer the same level of security as using your card, but they’re much more convenient, as you don’t need to enter card details every time you want to deposit or withdraw.

You might be wondering if crypto is accepted at safe and secure online casinos, and the answer is yes, sometimes. Sites that accept crypto can apply for UKGC licenses, the same as any other gambling site. Cryptocurrencies like Bitcoin, Litecoin, and Ethereum are a secure way to fund your online casino account, especially if you don’t want to share personal details like your bank card number with the casino site.

Are Safe and Secure Online Casinos Legal?

Secure online casinos are legal in the UK as long as they hold a license from the UK Gambling Commission (UKGC). The UKGC has a whole lot of strict rules and standards a casino site has to stick to in order to be granted the license. For example, games need to be tested and audited for fairness, and all of the payment methods need to be totally secure.

You should only ever play at licensed sites with the UKGC stamp of approval. If you play at unlicensed casino sites, your money could be at risk, and the games might not all be fair.

Worst of all, you won’t have any protection if the casino changes their terms and conditions on a whim or simply decides not to pay out your wins. Before signing up at any online casino site, you should check for the UKGC licensing details in the footer of the site.

All of the casinos that we recommend here at Bookies.com are licensed, so it’s totally legal for you to sign up and play. You’ll just need to be aged at least 18, and physically located within the UK. As we mentioned, the casino site will usually use available information (like the electoral roll) to attempt to verify your account before you can log in and play for the first time.

If the casino can’t verify you, you’ll need to send some documents such as a copy of your photo ID.
