Best Online Casinos UK

There are hundreds of UK Online Casinos on the web. But which one is the UK's Best Online Casino  today? The recommended UK online casinos listed here at Best casino sites have been through an arduous vetting process so that you don’t have to. We aim to make it easy for UK gamblers to find the best online casino sites at the drop of a hat. We want you to be safe in the knowledge that you’re playing safe and licensed online casinos which will give you access to the best games, the best bonuses, fast pay-outs and most importantly: put their customers first.

Which are the best online casinos in the UK?

When we say “best” we really mean best on all accounts, not just design or the first thing you usually see advertised: the welcome bonus. Getting access to the best casino games and slots, getting high value for the deposits you put in, getting lightning fast cash outs and access to fun promotions all count too. But alas, every casino fan is different, that there can be no “one” best casino – there are tons; you just have to pick the most suitable one for your tastes!

At Best Betting Sites, we’ve spent over a decade reviewing UK online casinos and can honestly say there’s a top list of the best online casinos that we’d recommend any day. Some are newer, and some are older, however we do tend to look out for newer casinos as they usually offer something unique.

Deciding on the best UK casino site for you

Before you get to that list however, here’s what you should be looking out for and asking yourselves when you’re deciding which casino site to play at next:

Is the casino recommended by casino betting guides like us? Our casino and betting experts alike have scrutinised dozens of online gambling sites to come up with a list of the best new casino sites online. Check around, you will find other trusted casino guides that also do what we do. See what they’re saying too! We want you to find 100% safe and secure UK casinos and know that you will only ever find UK Gambling Commission licensed sites recommended here.

Software, Games and Graphics

Does the casino offer all the games you want to play? Look for a variety of games with top quality graphics from leading games vendors including Netent, Microgaming, Evolution Gaming (best for live dealer games), Playtech, Yggdrasil, Play N Go, WMS & IGT. A good tip is to also look out for the large paying progressive jackpots too. We’re talking about the big ones that offer jackpots over £1 Million. These games usually include Mega Moolah, Mega Fortune and Hall of Gods Slots to name a few. It’s usually a bench mark of a good casino site.

The reason why we wanted to add a full and in depth page about online casinos on this website (which is admittedly about online sports betting) is because it's become really common in the past couple of years that online betting sites, such as the ones we recommend on this site, also offer casino games.

And we don't really mean a few, we mean the whole lot! You name it, slots, roulette, blackjack, jackpots and live games. So most of the time, if you're looking for the best casino sites then usually you won't need to look further than a decent online bookie.

Licensing, Pay-out Report and year founded

As we already mentioned, you will only find casinos which are licensed by the UK Gambling Commission on Casino Fans.  You want to be sure that any new casino you decide to play at is safe, secure and trusted and by having that UK license is a seal of that.

The same goes for year founded. Of course, if a casino is brand new, it’s harder to know much about it but usually you will find that it’s owned by an established iGaming company who own several other well established casinos, so you’re good to go. Usually, older, well-established casinos are typically the most reputable and offer higher RTP but new casinos which have older sister casino sites are going to be fine too.

Customer Support Options

Search for a site with a strong customer support department, which is available around the clock, preferably via live chat, phone and also email (with a free phone number). This is quite important as you will want to ensure your questions are addressed in a timely manner and you have the chance to speak with someone directly, if you should need to.

Bonuses, Promotions and Rewards

Ask yourself “How good is that welcome bonus?” Check out how you claim the bonus first of all. Sometimes, a large deposit bonus is given to you over a series of deposits and not all at one time. Free Spins usually will require a deposit, so make sure you check the finer things including wagering requirements and always, and we say it again always, read every bonus’ own Terms & Conditions.

No need to worry about most bonuses however, as many UKGC licensed casinos need to observe rules and regulations when it comes to wagering to fulfil their license requirements, so you shouldn’t expect any sneaky terms in the bonuses you see at our recommended casino sites.

We also suggest that you look for lots of great promotions, loyalty bonuses and if it applies to you – a high roller rewards program. This ensures that you’re offered plenty of perks and benefits every single time you play. New casinos usually are the best for this because they need to be competitive – and offering high value is one way to attract new customers.

Banking Options: Supported Payment Methods

It's important to seek out an online casino site that will provide you with plenty of easy deposit and withdrawal options and  moreover - timely, fast withdrawals. It's your money and one rule of thumb for us is that you should never have to wait days or even weeks to get your money. Most online casinos offer a plethora of funding methods which make the whole process rather effortless, including PayPal, PaysafeCard, Bitcoin (and many other Crypto Currencies), InstaDebit, Skrill, Neteller, Mastercard, Visa, Direct Bank Transfer and so many more.

Languages & Currencies

You will want to make sure that your choice of currency is supported as well as your spoken language. Most likely if you’re reading this you’re residing in the UK, but the best online casinos will offer plenty of different currencies for you to deposit in, including Crypto currencies as well as offer other main supported languages aside from English.

With these tips and criteria, you should have no trouble finding the best online casino sites in the UK from our lists. Remember to read reviews, testimonials and whatever else you find in Google to give you a feeling whether the casino is right choice for you. 

New Online Casinos vs Established Casino Sites

A common topic of debate here in the UK is the “New Vs Established online casinos” discussion. Why highly regard a brand new casino over an established one which is years old? It’s personal choice that matters at the end of the day, however it must be said that new online casinos have found favour among many casino players when it comes to the innovation and originality of the casino site itself.

New casinos have time after time proved to players, that despite being new to the industry, they will offer fresh ideas in design and also gamification. Gamification for the record, is the process of integrating a game system into the casino to motivate participation, engagement, and loyalty.

This in turn will offer players unique promotions that are usually tailor made, paid in real time and engaging - all from one’s own casino account! These types of casinos have in the past been considered pioneering (Casumo was one of the first back in 2013) but as we say – it all depends on your tastes. What one might be over the top and distracting for one, for the next it may not.

To conclude, both new and old online casinos have created a great deal of healthy competition in the casino industry, which is only good news for players alike; it’s has created a market of sheer choice, bigger and better welcome bonuses, huge prize-pool jackpots, tons of free spins and so much more!
