Bonuses & Promotions from Licensed Online Casinos

The best online casinos, UK and worldwide, will offer new players a welcome bonus for signing up. Some sites will double your first deposit, also referred to as a match deposit bonus, others will hand out free spins (no deposit or with payment), and the best casino sites offer both to new customers.

After registering with the operator, you can also expect additional gifts, such as weekly competitions, daily promotions, and a loyalty scheme. Reputable brands like PlayOJO even waived their wagering requirements on free spin offers, meaning that you can withdraw winnings immediately.

However, there is a catch.

Sometimes, these offers sound too good to be true, and it’s time to be extra careful before making real money deposits. The best online casinos have obtained licenses from reputable gaming commissions, such as the UK’s Gambling Commission or Malta’s Gaming Authority. Signing up with a licensed site means you’re protected by the regulatory bodies’ strict requirements around fair games and customer protection.

It’s not always straightforward to distinguish regulated and unregulated online casinos, which is why we have put together a list of the UK’s top 20 casino sites with a valid UKGC license.

Casino Games – From Online Slots to Bingo

Next on the checklist is the website’s game selection.

While the best online casino sites partner with various software developers and therefore offer hundreds, if not thousands, of titles, players still need to think carefully about the type of content they want to play.

For example, if you prefer playing online slots, you might not want to register with an operator like Mansion casino. While it’s a 100% legitimate UK online casino, it partners exclusively with Playtech, and you won’t be able to play any cutting-edge online slot games like the Megaways range.

On the other hand, Bingo lovers should ensure that online casino offers bingo games as part of their portfolio. While most of them do, you shouldn’t just assume it. It can even make sense to sign up with a bingo site instead, as most of them offer a small range of online slots as well.

As you can see, thinking ahead means not wasting time on signing up with an operator that doesn’t meet your needs. Luckily, the best online casinos tend to offer a healthy mix of all types of games and also regularly update their portfolio with new game releases.

Deposits & Withdrawals

Financial transactions are a crucial aspect of the player experience when gambling online for real money. Nothing is more frustrating than slow or costly deposits and withdrawals.

Good online casinos offer their players various ways to deposit and withdraw funds, including but not limited to the following:

The UK’s Gambling Commission officially banned the use of credit cards at online casinos. If you come across an operator that still accepts them, you can be sure you’re about to deposit money at an unlicensed casino site.

Which payment method to choose comes down to your preference. E-Wallets are the quickest way to deposit and receive funds, but they typically also have the highest fees.

Bank transfers are usually the cheaper option, but depending on the online casino, withdrawals can take up to 10 days to hit your bank account. The top online casinos list their fees and processing times on their website, and we recommend reading through them to avoid disappointment.

Safety And Regulation

We cannot stress enough the importance of regulation in online gambling. When risking your money, you want to be sure that games are fair, personal information is protected, and withdrawals are honoured.

The best online casinos hold licenses in their jurisdiction, such as the United Kingdom. You should only register with regulated casino sites to ensure your information and money are always protected.

We listed some of the UK’s top online casino sites above, but we also want to guide you to the best operators for a wider choice. The table below includes 66 gambling companies that run between two and 200 sister sites. Each link takes you to the operator review page, which contains information about their license status as well as a list of all sister casinos.

Summary

Hundreds of online casinos are available to players in the UK, and we hope our guide helps you find the perfect site. Keep in mind the following when choosing a casino online:
