1: Vic UK – Still The Best of the New Casinos   

Year established: 2022 

Welcome bonus: Get up to £200 in bonuses + 100 free spins (Code: VICGMBLR)  

Our editor’s view: “An online partner of the famous London Grosvenor Victoria, the Vic Casino tops the charts as our number one new online casino in 2025. Operational for just a few years, this is a brilliant place for live games, slots, and classic table games. I also love the dual welcome bonus – sign up today with our unique promo code for up to £200 in bonuses on your first three deposits and 100 free spins for top slots.  

Pros & cons  

2: MegaRiches – Our Favourite New Casino for Classic Table Games   

Year established: 2024  

Welcome bonus: 100% deposit match up to £25  

Our editor’s view: “I’m often disappointed that online casinos neglect their RNG table game lobbies in favour of live dealer titles. However, MegaRiches has delivered an outstanding offering of classic blackjack, roulette, video poker, and baccarat games. My favourite is Atlantic City Blackjack, which has a high RTP and numerous side bet options. I’d like a bigger welcome bonus from MegaRiches; otherwise, this is one of my favourite new online casinos in the UK.” 

Pros & cons  

3: Pub Casino – The Best New Online Casino for Slot Games  

Year established: 2023  

Welcome bonus: 100% up to £100  

Our editor’s view: “What’s not to love about a beer-themed online casino? I couldn’t wait to play at Pub Casino when it launched in 2023, and I wasn’t disappointed. You can play over 800 of the world’s best and newest slot games from Pragmatic and other top studios, which is my favourite thing about this platform. Sure, I’d like to see the 40x wagering lowered, but it’s not enough to put me off this unique online betting site.”  

Pros & cons  

4: Buzz Casino – A Top New Casino for Bingo Fans  

Year established: 2023  

Welcome bonus: 200 bonus spins on Blue Wizard Megaways Fire Blaze  

Our editor’s view: “I’ve been a customer at Buzz Bingo for a while now, so I was intrigued when they released Buzz Casino in 2023. I love that you can use both sites with the same account, and there’s no shortage of jackpot slots. Even the welcome bonus gives you 200 spins on Blue Wizard Megaways Fire Blaze, one of my favourite jackpot slots right now.” 

Pros & cons  

5: Barz Casino – The Best New Casino for Game Variety  

Year established: 2021  

Welcome bonus: Up to £300 on your first deposit + 50 free spins  

Our editor’s view: “Tune up your air guitar and dive into Barz’s 2,500+ strong game lobby for an incredible online casino experience. This is one of the best new casino sites in 2025 for game variety, with all bases covered. Play live dealer, table games, poker, roulette, scratch cards, blackjack, drops & wins, Megaways, classic slots, and cluster games from studios like Red Tiger, NetEnt, and Pragmatic. If game variety is your priority, Barz is the casino for you.”  

Pros & cons  

6: NeptunePlay Casino – The Best New Live Casino in the UK  

Year established: 2020  

Welcome bonus: 100% up to £50 + 110 free spins  

Our editor’s view: “NeptunePlay might not be the newest casino on this list, but it’s maturing like a fine wine after five years of operation. Whenever I want to play live dealer and game show titles, I sign into my NeptunePlay account. Live blackjack, roulette, baccarat, and poker games are in the lobby, while most top game show titles are here. I’m a huge fan of Lightning Storm Live and partial to Funky Time, Mega Ball 100x, and Monopoly Live, which you will find at NeptunePlay.”  

Pros & cons 

7: VegasLand Casino – The Best New Deposit-Match Casino in the UK  

Year established: 2022 

Welcome bonus: 100 spins + £200 bonus (Code: BGVEGAS) 

Our editor’s view: “If you want to double your money after registering at a new online casino in the UK, VegasLand is for you. When you enter the promo code “BGVEGAS,” you can double your money up to £200. You will also receive 100 free spins for specific slots. When you’re in, there’s a lot to like about VegasLand, but I hope the developers add more table games in the future, as there’s only a small selection currently available.”  

Pros & cons  

8: Mogobet Casino – The Best New Casino for Ongoing Promotions  

Year established: 2024  

Welcome bonus: 100% up to £200 + 20 free spins for Book of Dead  

Our editor’s view: “I love Play’n GO’s Book of Dead slot, so I was thrilled to kickstart my experience at Mogobet with 20 spins on this classic Egyptian-themed game. However, the real draw of this new casino is the ongoing promotions. When you play regularly at Mogobet, you can claim up to 75 free spins per week and earn cashback, spins, and bonus cash every “Rewarding Wednesday,” making Mogobet the ideal place to play if you’re hunting for ongoing casino promos.”  

Pros & cons 

9: 7bet Casino – The Top New Megaways Casino in the UK  

Year established: 2024  

Welcome bonus: 100% deposit match up to £50 

Our editor’s view: “I absolutely love Megaways slots, as the thousands of winning ways add to the excitement of spinning the reels. The extensive Megaways lobby at 7bet is my favourite thing about this new online casino – I’ve already played most of the 50+ games. If you’re new to Megaways gaming, I highly recommend The Dog House Megaways and Madame Destiny Megaways, both by Pragmatic Play. But you will also find numerous Megaways games from Big Time Gaming here.” 

Pros & cons  

10: Myriad Play Casino – An Excellent New Casino for fast payouts  

Year established: 2024  

Welcome bonus: 100% deposit match up to £50  

Our editor’s view: “This new casino certainly lives up to its name, with myriad slots, table games, and live dealer titles. However, I recommend Myriad Play for its fast payouts. When I signed up and played here with a PayPal deposit, I received my winnings within one hour of requesting them. This is super fast and one of the quickest turnaround times I’ve experienced. Most other payouts should be in your account within 24-48 hours.”

Identifying the Best New Casinos – The Only Checklist You Will Need  

The above sites are the top new online casinos in the UK in 2025. However, new casinos are launched yearly and offer various games, bonuses, and exciting features.  

So, follow the checklist below to help you identify the best new casino sites in the UK market. We introduce the features and characteristics we expect to see in new online casinos so you can easily identify the top-rated sites for yourself.  

Check the Licence   

Dozens of new casino sites appear worldwide throughout the year. However, many of these are not legally available in the UK, as offshore regulatory commissions licence them in places like Malta and Curacao.  

Therefore, the first thing you should do before signing up for a new online casino is to check its licence. To be legally and legitimately available to British players, it must have a licence from the UK Gambling Commission (UKGC).  

This point is non-negotiable. Don’t sign up if the new casino is not licensed in the UK. It’s as simple as that. At British Gambler, we take licensing very seriously and only ever recommend UKGC-registered sites to our readers.  

Consider the Game Variety  

When you’re happy that your chosen new casino sites are licensed and regulated in the UK, you should consider the game variety at each site. 

Every casino customer is different, but we recommend looking for sites that offer slots, table games, live dealer titles, and instant-win games by top-rated providers such as Pragmatic Play, NetEnt, Play’n GO, Games Global, and Playtech.  

There’s no right or wrong number of games that you should see at a casino, but we offer high ratings to sites with at least 1,000 games from 20+ providers.   

Our editor on game variety: “Quality usurps quantity when it comes to game variety at online casinos. I always check the providers behind the games rather than fixating on the total number of games in the lobby.  

“For instance, I’d much rather play at a casino with 1,000 games from top-tier, multi-award-winning studios than at a site with 10,000 games from suppliers I’ve never heard of. Crucially, top-tier studios have their games checked by eCogra and iTechLabs for fairness, giving you peace of mind as you spin the reels.”  

Review the Bonus Terms  

You don’t have to be a casino pro to differentiate between good and bad offers. In fairness, most new online casinos we review offer good-value promotions, as they see it as a viable way of attracting customers away from more established sites. Specifically, you should check the following terms to help you find good-value deals at new casino sites in the UK:  

• Wagering requirement: This figure indicates how much you must spend to play through bonus winnings before requesting a withdrawal. The lower the wagering requirement, the better—the best new online casinos have wagering requirements between 10x and 30x.  

• Bonus amount: Provided the wagering requirement is fair and reasonable, a £100 offer is better than a £10 offer.  

• Free spins: As illustrated in our top list above, the best new online casinos in the UK offer free spins alongside bonus cash. You can use these spins on top slots like Book of Dead and Starburst.  

• Minimum deposit: Unless you access a no-deposit bonus, you must make at least the minimum deposit to trigger the welcome bonus. This is £10 at most casinos in the UK, but it may be as high as £20 at some sites.  

• Max win (conversion): You should also note that new casino sites restrict the amount you can win from bonus funds and spins. This is known as the max conversion. We typically find this to be between 5x and 10x, but the higher, the better.  

• Timeframe: You should also check how long you must trigger the bonus and meet the wagering requirements. This can range from 24 hours to 30 days. If you have a limited time window, only trigger the welcome bonus when you’re ready to deposit and play. 

Our editor on new casino bonuses: “In my experience reviewing new casino sites, I find these platforms go to town on bonuses and promotions. This is because they must go the extra mile to attract customers away from the more established sites in the UK market.  

“So, generally speaking, you can often access bigger and better bonuses at new online casinos than at more established sites. Sure, there are exceptions to this rule, but the quality of the bonuses is one of the main reasons to sign up for new casinos over long-established platforms.” 

Different Payment Methods  

Another draw of new casino sites is that they offer a wider variety of payment methods than traditional ones. The top sites offer 10+ payment methods, including debit cards, bank transfers, e-wallets (PayPal, Neteller, etc.), pre-paid cards (Paysafecard), and mobile wallets (Google Pay & Apple Pay).  

Although there’s a growing trend of new crypto casinos in the online gambling world, such platforms are illegal in the UK. You cannot gamble with cryptocurrencies in the UK, and credit card deposits are prohibited at UKGC sites. 

Mobile-First Approach  

One thing you can be confident of when signing up for a new casino is that it will be mobile-optimised. Some new casinos adopt a mobile-first approach, recognising that most players in 2025 prefer playing slots and table games on smartphones.  

If you plan to play casino games on your phone, we recommend new casino sites with a dedicated mobile app for Android and iOS devices. Alternatively, if you don’t want to download an app, you can play games by signing into the casino via a mobile browser like Chrome or Safari. 

Our editor on mobile gaming at new casinos: “I advise you to download a casino’s mobile app if available. You can access the game lobby without signing in every time. Also, I often find that new online casinos offer exclusive promotions via the app, which you will miss out on if you play games via a mobile browser.” 

How We Choose the Top New Online Casinos: The British Gambler Review Process 

New casinos have exceptionally high standards to meet, given that hundreds of online casinos are already available in the UK market. Even though these sites are new, we review them by the same standards and with the same criteria we use for all other sites. Namely:  

✔️ The UK Gambling Commission must regulate the site.  

✔️The sign-up process should be straightforward.  

✔️The casino must have a wide variety of games, ideally over 1,000+ from 20+ providers. 

✔️There should be a generous welcome bonus with low wagering requirements (20x or lower). 

✔️Deposits should be instant and fee-free. Withdrawals should be processed in 1-3 days. 

✔️The site must be available on iOS and Android mobile devices. 

✔️There should be multi-channel customer support available for all customers. 

✔️The site must have positive reviews from verified users.  

That said, we also expect new sites to be intuitively designed with sleek and modern interfaces on mobile and desktop. Moreover, when reviewing new casino sites, we expect to see the latest games from the top studios, not just the back catalogue. This is another USP and a reason to choose new online casinos over more established betting platforms.  

Before signing up for one of our recommended sites, check out the latest casino promo codes for 2025. Don’t forget to enter the code when you register for an account to access bonus cash, free spins, and other perks.
