What are non-gamstop gambling sites and what do the UK gambling laws say about GAMSTOP?

The GAMSTOP scheme is an UK program which allows players to self-exclude from all casinos within the country. It’s under the control of the UKGC and all websites which are licensed by them are required to comply with the policy. Non gamstop online gambling sites are those that work with off-shore licenses, be it from the Curacao Gaming Control Board, Gibraltar Gambling Commission or the MGA. Because of that, they don’t comply with the gamstop exclusion, hence the name non-gamstop casinos.

How do we help you find the best gambling sites not on Gamstop?

Our team of experts has made their goal to help you find the best gambling opportunities out there. To do so, though, we review the sites to the little details and look for some main features:

• License
  Since all casinos licensed by the UK Gambling Commission are required to comply with the GAMSTOP self-exclusion program, we separate those from the non gamstop online gambling sites and show you which casinos work under off-shore licenses. Usually those are issues by the Curacao Gaming Control Board or the Malta Gaming Authority.
• Site usability
  We take a good look at the design, navigation and functions to see if the site’s got an user-first interface which will make your gaming sessions more fun rather than tiresome.
• Variety of games and sports events
  Of course, our reviews also take into consideration if the given online gambling site features a lot of games, what are they, is there a sportsbook available, etc.
• Payment methods and limits
  Our experts also check the payment methods available and guide you through the limits to help you understant if the casino is a good enough choice for you.
• Bonuses
  We also strive to give you a complete list of the top bonuses available on non gamstop online gambling sites.
• Mobile play
  As the digital era advances, more players are turning to their smartphones for betting. So we check the mobile compatibility of the casinos we review to make sure they are mobile-friendly, with or without an app.
• Player reviews
  We also take into account what other players say about the online gambling websites we review to notify you about any negative comments or potential issues.

Our team does their best to follow the most recent trends as they develop; to stay up-to-date with the newest gambling sites out there and review them as soon as possible as well as update the reviews of all other betting platforms that GamblerHub.co.uk features to make sure you have all the information you need to find the best UK casino sites.

Registration and KYC at the best UK casinos not on Gamstop

If you've decided to set up an account with an UK online casino from our list, you can do so rather quickly. Usually they all have a registration button somewhere at the top right corner, only the name might be a bit different ('Join', 'Sign up', etc.).

Now you'll be required to fill a quick form with relevant contact info and account username and password. Only a couple minutes and you'll be done after which you can login and start playing your favorite games available at the best casino websites. Still, don't forget to go through the KYC procedure. It requires you to send a scanned ID document (or a photo of one) to the casino's support team so that they can make sure the personal data you've put into your account is accurate and, well, yours to use.

Yes, verification isn't always required right away but if you don't do it early on, when you request a payout, you'll have to wait until the team verifies your identity before a withdrawal is approved and processed.

What bonuses can you find with the best casinos not on Gamstop?

Well, as usually is, all gambling sites feature different bonuses. Still, let’s see a broad description of what you can find if you decide to join one of the top casinos on our list:

• Welcome bonuses
  Of course, such are available in almost all non gamstop casinos. They are a way for the site to attrach new customers with extra cash, free spins or free bets. Most common are the deposit match bonuses coupled with free spins.
• No deposit offers
  Rarely found, they can give you some of the best bonuses out there. Most commonly, though, they are available for existing customers.
• Free spins and bonus bets
  One of the most exciting bonus in offshore casino sites that offers you to play specific slots or wager on qualifying bets without using your own money.
• Loyalty bonuses
  Those are special promos available for existing customers who’ve played at the new casino site for a while.
• Tournaments
  Almost all casino sites also offer tournaments where you can play on your favorite slots or wager on certain sports events and claim points to go up the leaderboard and try to win part of the prize pool.
• Cashback
  With those types of offers you can claim money back on your losses, usually as a percentage of net lossess accumulated over a certain period of time.
• Rakeback
  The same as cashback but the bonus money are calculated on your total bets, not only on your losses.

As we always advise, take a good look at the bonus terms and condition before you claim the offer in order to see if it’s truly worth it and how to wager it over.
