Why Should You Try New Casino Sites?
There are many reasons why it can be worth joining new online casinos, even if you're happy with the casino that you're currently playing at. These are often linked to the fact that as there are an estimated 175+ UK online casinos, new gambling sites need to stand out from the crowd.
One way they try and do this is by offering welcome bonuses that involve a larger deposit match and/or more free spins than competitors, allowing you to sign up and try out the casino with a boosted bankroll. Some follow this with consistent reload rewards such as no deposit bonuses in a bid to keep players.
Many new online casinos equally boast large games selections featuring the latest and most popular releases from award-winning software providers. The best new casino sites in the UK also tend to accept a wide range of modern banking options, like e-wallets such as PayPal and Skrill alongside mobile payments via Apple Pay.
Another major perk of playing at new real money online casinos is that they’re generally more accommodating of mobile players. Most UK casinos launching in 2025 have casino apps, to ensure they can attract the attention of the increasing number of mobile casino fans who prefer to gamble and play games on their iPhone or Android smartphone.

JOIN MYRIADPLAYHow We Rate New Casinos
We hold new casino sites to the same standards as established casinos in our casino reviews. For us to recommend a new UK casino site, it needs to tick each of the following boxes:
Valid licensing: The first thing we do is check that a new online casino is properly licenced by the Gambling Commission (UKGC), meaning it’s been verified as providing a safe and trustworthy platform.
Game quality and quantity: Top new casino sites have huge and varied games collections, including popular slots, table games and live casino titles. The games should also be tested and approved as providing fair outcomes by eCOGRA.
Easy transactions: When we review new UK casinos, we check to see if there are numerous popular payment methods accepted for deposits and withdrawals. The site should ideally offer fee-free transactions with quick payout times.
Generous bonuses: As mentioned, a big draw of new casinos online is the opportunity to take advantage of welcome and new casino no deposit bonuses. However, they also should offer consistent and generous reload rewards with reasonable wagering requirements and T&Cs.
Reliable customer service: It’s easy for new UK online casinos to say they put players first, but the only way to ensure this is by testing the customer support. This should ideally be available 24/7 across numerous channels including email, live chat and phone.
Frequently Asked Questions
How do I know if a new UK casino site is trustworthy?
The best way to guarantee that you play at completely safe new casinos is by only visiting the new casino sites we recommend.
However, if you come across a new casino that’s not featured here, you can check it’s trustworthy by ensuring that it’s verified and licensed by the likes of the Gambling Commission, Malta Gaming Authority (MGA) and eCOGRA.
Why should I switch to a new online casino?
There are multiple benefits to signing up at new casino sites, starting with the chance to claim a welcome bonus. The best new online casinos are also home to big games collections, brilliant mobile apps, generous reload bonuses and a variety of accepted payment methods.
Do new casino sites have the newest games?
The games available at every new UK casino will be different, but many tend to have the latest releases from top software providers in a bid to attract players. They will likely also have a fantastic catalogue of older games as well, to ensure they can offer something for everyone.
Are bonuses at new casinos better than those at other UK casino sites?
While we can’t guarantee that the promotions at a new casino will involve larger amounts of bonus funds and/or free spins than those at a gambling site you already use, it’s common for new casinos to try and provide bigger welcome bonuses than competitors in a bid to attract new players. When playing at new casinos, it’s still just as important to ensure that the bonuses you’re claiming also have reasonable T&Cs and wagering requirements.
Are the payout percentages or RTP better at new online casinos?
Generally not, as while a new casino may have more and/or newer games than other sites, these will still feature varying return to player (RTP) rates. The average RTP for online slots across all UK casinos approximately 96%, so if you’re looking for the best payout rates, it’s more advisable to search specifically for high RTP percentages as opposed to recently launched casinos.
