Getting Started in Online Casinos: A Guide for New Players

Our industry experts and real-life gamblers will guide your steps from registering to your favourite UK online casino to choosing your bonus, making your first deposit and playing.

How to compare the current best online casinos UK using our site

You can’t just register on the first site that catches your attention. Comparing your online casinos using our criteria allows you to choose a site based on the real facts we share with you.

• Our curated selections make security checks obsolete.
• We group the best UKGC-licensed casinos according to specific criteria.
• Some of the most popular filters in the UK include slots, live games payouts or bonuses.

How to sign-up in an online casino

1. The process is standard to create a new profile on one of the best online casinos UK.
2. You have a few boxes where you must write down your personal information, like name and address, contact info, and sometimes a few details about a payment method that you will link to your gambler account.
3. Remember not to try to use details not belonging to you  when creating an account. You have an obligation to send accurate data and only use your IDs and source of funds.

Why do you need to complete the KYC process?

When a casino asks you to send clear pictures, scans, or screenshots of your IDs, they do it to verify that the name and address that you entered while signing up are actually yours. The KYC process is a paperwork verification method that adds an extra layer of safety and support to the entire gambling industry by combating money laundering.

All UK casinos will ask you for financial KYC at a certain point. There, you need to show them where you get your funds and demonstrate that the means of payment that you’ve been using are yours or assigned in your name.

Strategies to Minimize Risk

How to use sign-up bonuses in UK online casinos safely

1. Start with free spins on sign-up in online casinos since slots are the easiest game.
2. You should move up to deposit bonuses only after comparing the best options in the UK.
3. If you choose no deposit casino bonuses from verified sources like our experts’ list, you enjoy an extra layer of safety and complete information in an easy-to-digest presentation.

Always read the Bonus Terms

Free bonuses come with strings attached, so it’s best to understand all your requirements before using them. Moreover, regarding 1st deposit offers on sign-up, not reading the bonus rules may have negative financial implications.

Here’s a quick reminder of the most important bonus terms at online casinos:

• Min deposit: the amount you need to deposit to activate your bonus. It starts at £1, £5 or £10 in the UK;
• Bonus value: the amount of promotional funds you receive from the casino site after your deposit has been processed;
• Eligibility: some bonuses are for new players, while others, particularly reload bonuses, are suitable to claim only by existing players;
• Welcome package: a promotional bundle that contains bonuses for multiple deposits along with free spins, usually spread between 1-5 days;
• Wagering requirement: the number of times you need to play through the bonus value or the deposit and bonus value combined before cashing out real money from it;
• Expiry date: the date after which wagering the bonus is no longer available and you lose any unused bonus funds.

Best Payment Methods to Use in UK Online Casinos

We recommend the most convenient methods for depositing and cashout in UK online casinos. For more details about our testing procedures for online casinos, see them highlighted in each individual review.  The values for transaction limits and processing time are estimates based on our experience with the best online casinos reviewed on this page:

Our best recommendation for UK players is to choose a PayPal casino that combines payment speed and reasonable limits for the average player. You should settle for a debit card if you deposit more than £5,000.

How the UKGC Protects Your Security

The United Kingdom Gambling Commission regulates all the gambling and betting activities in the Kingdom. This is the institution that licenses online and land-based operators and checks if their offered products respect the legislation.

They are the ones that create, update, and enforce the legislation. They do that as a result of the joint effort of law experts, psychologists, gambling addiction therapists, and operators alike. Their goal is to set up healthy standards for all sides.

How the UKGC protects you

The UKGC enforces strict standards upon online casinos which act as shields that protect you from scams:

• The UKGC protects your financial situation by not allowing operators to steal your money, lock it in their accounts for no reason, not allowing you to take them back, etc.
• On top of that, they force casinos to be transparent with you. The operator is bound to inform you, in simple terms, of what happens to your funds, where they are stored, in what conditions can they be transferred, etc.
• The casinos are also required to protect your personal data. It needs to be stored securely, not accessible to anyone else, collected minimally only with the details that are needed to verify that the account is yours and you are an adult.

License granting system for online casinos in the UK

1. When a UK online casino applies for a license, all these features fall under supervision.
2. The site is tested for over 6 months before they get the seal of approval.
3. Then, randomly, they go back and test if the validity of the terms and promises are still respected.
4. A license can be revoked at any time if the provisions are not respected.

UKGC stats

How to verify the casino license and stay safe

Here’s the process we go through when verifying. We suggest you follow the same trail as us:

1. Go to the main page of a casino of choice and scroll down to the footer.
2. Read the text there (sometimes it might be presented in a smaller font than the rest of the text) and scan until you get to the part with a hyperlink.
3. Click on the hyperlink. It should redirect you to the UKGC site, specifically the page where the main operator is listed, and all their licenses are listed (expired, new, or pending).

That’s it! If you see something similar to the screenshot above, that means that the UKGC licenses your casino at the moment, and it has passed all the safety standards required.
