New Online Casino Sites in 2023

One thing you’ll notice about our list above is that it’s subject to regular changes. These are 2023's brand new online casinos in the UK after all, they can’t stay that way forever.

Our aim is to review a new casino, right from launch date and if they get the green light from us, you’ll be the first to know. We base our ratings on a series of elements including casino games, bonuses and payment methods. Our top priority though is safety as well as overall usability, but we’ll take a look into this in more detail later.

With trusted casino sites like 888Casino, William Hill and the rest of the big giants, you’re bound to question whether a new casino is worth taking a chance on. They have yet to gain the reputation of the old-time favourites or the steady player base for that matter. That doesn’t mean that brand new online casinos aren’t worth joining.

There are new UK online casinos launching regularly, even we can’t keep track of them all. Because it can take years to reach that ‘well-established’ status, a lot will do everything in their efforts to stand out.

Few are successful, but those that do shine through can sometimes actually end up being better than the bigger names in the casino market. While the latter can get complacent, new casino sites have to prove themselves. We’ve summarized these advantages and disadvantages in the table below.

Joining a brand new online casino will always present some risks. The brand name is usually unheard of which can make some players hesitant. They haven’t had time to build any street cred. Customers who trust their instincts though could be rewarded with a long list of perks.

New online casinos are known to offer state-of-the-art mobile platforms for instance, but we’ll get to that very soon.

Many of these UK-focused new online casinos accept customers from other regions, including New Zealand and Australia. Players from these regions can benefit from a larger pool of new casinos and take advantage of higher welcome bonus amounts. To find out to best new online casinos outside of the UK, click on your country of interest in the table below.

Are bonuses an important factor for you, when you choose where to play? The best new online casinos seem to think so. They know that having great bonuses is one of the top ways to catch your attention. Their offers tend to be very lucrative when comparing to the rest of the casino market. Both in bonus amounts and favourable terms. 

What can you usually expect? If you're new to the casino site, think of multi-tiered welcome packages with great mixes of free spins and bonus money.

If you already have an account, there will usually also be rewarding loyalty programs in place. Reload bonuses, VIP tournaments, cashback, exclusive bonuses, and more. Note though, the loyalty programs are often similar to established casino bonus offers. Simply because it's not feasible to up the antics there. They would lose too much. 

One thing to also be aware of: when you claim a new online casino welcome bonus, read the full bonus terms and conditions before accepting. You might not be eligible for the offer! New online casinos are often part of bigger groups. If you played at a sister site, you could be prevented from getting welcome packages.

Luckily, the new online casinos licensed in the UK are transparent and will make it very clear, if you are at any risk of not being eligible.   

If you have any experience with online casinos, then you probably know the drill when it comes to no deposit bonuses. They’re a great opportunity to try out to test out a site before committing. Due to changes in UKGC regulations though, they are becoming harder to come by. That said, given the nature of the bonus, if any casino is going to offer this type of bonus, it’s going to be a new online casino site.

New UK casino no deposit offers either come in the form of bonus money or free spins. The latter are the most common and many times this is coming from the software providers. Just remember to check back to the full terms. From wagering requirements to cashout limits to bonus code systems, there’ a lot to watch out for.

When we speak of promotions at a new online casino, loyalty systems are also worth a mention. It’s no secret that online casinos want to reward their regulars. Newcomers have the advantage of being able to learn what works and what doesn’t.

The community has grown fond of objective, mission-based rewards. This kind of system is distinctive of new online casinos. However, certain others that are steadily becoming “well-established” have employed them as well. We must point out that the Gambling Commission is looking to tighten restrictions related to VIP programs. We may start to see less new casinos offer this type of promotion.

Mobile optimised casinos are currently booming in the UK. Casinos that have been around for a while now have all had to adapt to the latest trends. New online casino sites, on the other hand, are at quite the advantage. They were born into portable gaming and with that, we have seen the rise of a new strain known as mobile-first casinos.

When it comes to new mobile casino sites, you can expect only the latest HTML-5 technology. Their instant play web apps are fully compatible across all major devices. Some actually do one better and offer Android and iOS users the option to download an app. Either way, the interfaces are usually stunning. Often a time, new casino sites actually look better on mobile than they do on desktop.

Security is always a topic up for discussion when it comes to the online world. Players tend to find comfort in casinos that have been around for long enough. If they were doing something wrong, they would have been caught out by now.

A new online casino can’t offer customers this ‘safety net’. That doesn’t necessarily mean that they can’t be trusted. We have our list of the best new casino sites UK has to offer as living proof.

For more information, we suggest reading our reviews. All of the UK new online casinos recommended by CasinoCountdown are legit, licensed and audited sites. It’s not about how long a casino has been up and running. There are new online casinos that are part of large, well-established, organisations with clean track records.

If you prefer to do your own research, then there are certain things to look out for. A casino license from a reputable regulatory body like the UKGC is a must. Other things to look out for include their approach to responsible gambling as well as fair gaming.

Most will provide links to third-party support organisations like GamCare but we also look for a dedicated page with all of the right information. As for the games, a seal from an independent auditor such as eCogra is always a good sign. The better new casinos will go one step further and provide the latest audit certificates.

There are many new casinos that enter the market but only a select few get the green light from us. There are a number of boxes that they have to tick. Safety is by far the most important factor but it’s only the tip of the iceberg. We’ll take a look at what sets the top new online casino sites aside from the rest.

• Valid UKGC casino license: if a new casino doesn’t seem to make their licensing information clear, we suggest looking for an alternative.
• Advocates of responsible gambling: enough information to guide players who are at risk of problem gambling.
• Efforts to promote fair gaming: this is where we look for seals from the previously mentioned eCogra or other independent auditors like iTech Labs and GLI.
• Lucrative welcome bonus with fair terms: we’re looking for a generous new player bonus, with equally genuine terms.
• Good choice of payment methods: we don’t necessarily look for the largest banking portfolio but it's quality that we’re after. For example, PayPal is big at casinos in the UK.
• State-of-the-art game filters: rather than a large casino game lobby, we’re after one that is easy to navigate through.
• Round the clock customer support: while we give new casinos a bit of leeway when they’re setting up, we do expect them to be contactable 24 hours a day.
• Tiered VIP program: we like a new online casino that staggers their VIP program and makes it fully transparent.
• Overall transparency: we look for sites that make their terms clear from the get-go.

The list above will give you a better idea of how we go about reviewing new slot sites. Looks will always play an important role but this can often be subjective. The usability is what concerns us most. To further simplify things, we have picked out our new online casino of the month and provided more details below.

In a market as esteemed as the UK, there’s a lot to choose from. Scores Casino may be a fresh face but they’re one of those brands that fall under a larger group, namely 888 Holdings. They’re PayPal approved which always goes down well with UK players. Moreover, they offer customers a wide choice of games and promotions as well as an extensive VIP program.

The only thing we’re waiting for is 24/7 customer service but in the meantime at least they offer phone support which is more than most.

New online casino sites are attractive, and they have their own, unique qualities, as we have seen several times. Some are actually out-competing the big guns, just don’t go about making any premature decisions. As long as you lookout for the right traits, you’re headed in the right direction.

Of course, you can always check back to our list of the top new UK casino sites for some examples of those that can be trusted. Be sure to stay tuned because this isn’t the last you have heard from us when it comes to newcomers!
