Best UK Casino Sites Review Checklist
As mentioned already, we’ve performed hundreds of casino reviews. Meaning that we know how to separate the wheat from the chaff.
To give full transparency to our readers, we’re going to show you our exact process of how we do this. This will help you feel secure when joining one of our UK recommended casinos.
Wagering Requirements
The best UK casino sites have simple wagering requirements or no wagering at all! We understand that online casinos have to protect themselves from bonus abusers. So, we don’t expect all online casinos to offer no wagering bonuses.
But, if they do have wagering requirements, they shouldn’t be set at extortionate rates! For us, anything above 65x isn’t worth the bonus. That’s not to say that you can’t play at a casino that has higher wagering amounts. It’s just that we want you to be aware of these limitations.
Game Selection
Another part of our review process is checking which games each online casino offers. The best online casinos will have a blend of slots, live casino games, and more.
Having access to the most popular game providers is important. You shouldn’t have to register with many online casinos in order to play different games. We expect that casinos have over 10 slot providers, as well as 1 live casino provider.
Of course, there are other games outside of live casino and slot games. In fact, now more UK slot sites are offering Slingo games as a standard, this is on top of regular slots. If you’re interested in this game variation, we’ve got a dedicated page for the best Slingo sites.
Casino Bonuses
There aren’t many online casinos that don’t offer casino bonuses. That may be upon registration, or when making your first deposit. Casino bonuses are great as they give you extra to play with, meaning more entertainment time.
Some online casinos give out free spins no deposit or another no deposit bonus like £5 or £10. This isn’t always the case though for UK online casinos. What is always offered is the first deposit bonus. The bonus amount received is determined based on a percentage of your deposit. This ranges between 50 and 400%.
If the online casino is extra generous they may even include a second, third, or fourth deposit bonus. When casinos offer many deposit bonuses, this is called a welcome package. Depending on the casino you’ll also receive a set number of free spins. The spins will be awarded to a predefined slot machine. All you have to do is open the slot game and a message will appear stating that you have free spins.
Let’s face it, bonuses aren’t the be-all and end-all though. If they come with too high wagering requirements then we’d rather skip them, thanks!
We include them in our review process as it’s often a sign of how many bonuses you’ll receive as an existing player.
Brand Reputation
Some of the best online casinos have been around for decades. However, there are others that have just started out a couple of years ago.
The reputation of an online casino plays a big part in our review process. If a brand is known to be unethical to their players then they won’t be featured on our top list. That’s why you can trust that all the brands that we promote are licensed by the UKGC and are fair casinos.
Customer Support
The service that you receive as a customer at any company, not just online casinos is important. If you’re not happy with a service, where do you go? To the customer support team.
The best online casinos make sure that they treat players with respect and help them in every way possible.
In order for us to give an online casino top marks when it comes to customer support, they need to offer 24/7 support. There are many that do, including LeoVegas.
Further to this, the casino should have more than one contact method. The most frequent is having a live chat option, as well as a dedicated support email address. To be honest, we’re happy if they only have live chat, as instant messaging can quickly resolve any issues.
This section is probably an obvious point for most people, but one that we couldn’t miss!
Device Flexibility
Web technology is now super advanced. But, there are still casinos that don’t have a responsive product. Being able to play your favourite games from wherever is important. That’s why we critique casinos based on how well they function on mobile, tablet, and desktop.
Most of the top online casinos offer a mobile app that can be downloaded on iOS and Android devices. If they don’t, they will still offer a fully responsive mobile version that you can access in your device’s browser.
Something else is that the casino should be fast on mobile. This isn’t always the case, and it’s something that will lose a casino marks on our scoring.
Payment Methods
How do you play at a casino without making a deposit? You don’t. That’s why payment methods both for depositing and withdrawing are important. It shouldn’t be a hassle to deposit or withdraw at an online casino. That’s why we make sure to review which payment methods each brand accepts.
For us, the more options available, the better. As well as the ability to deposit and withdraw without incurring a transaction fee.
Common payment methods that we expect the top online casinos to have are:
- Visa
- Mastercard
- Skrill
- Neteller
- PayPal
- Apple Pay
- Pay-by-phone
- Paysafecard
It’s important to mention that you can no longer use credit cards for online gambling. This ban was introduced by the UK Gambling Commission and the Department for Culture, Media and Sport in April 2020.
Responsible Gambling
Firstly, gambling should be a form of entertainment. Online casinos that put this first are the best out there. If a player has a gambling issue it should be flagged internally straight away.
Responsible gambling is now at the forefront of the industry. Players must set limits on their accounts. If you’re not aware of these they are:
- Deposit limits
- Loss limits
- Wager limits
- Time limits
Each of these limits can be set up either daily, weekly, or monthly. As a player, you also have the option to temporarily deactivate your account, or even fully suspend it.
If you decide to exclude temporarily, casinos cannot send you any marketing communications. That’s until the time that you set has passed. You then have the option to prolong your timeout or make it permanent.
If you need help you can contact begambleaware.org or call this number, 0808 8020 133.
UKGC Licence
To feature on our website, the online casino must have an active United Kingdom Gambling Commission (UKGC) licence.
Why is this? This is to keep players safe, we don’t want our visitors playing at rogue online casinos. There are stories of people playing at unlicensed casinos and not getting their money back.
With a UKGC licensed casino, you can guarantee this, as well as that game RTPs are set to the correct amount.
In each casino review, you’ll find that we’ve included the licensee reference number. We hope that this will give you added peace of mind, knowing that you’re playing at a licensed UK casino.
You can even search the Gambling Commission’s database yourself by visiting their website.
How to Register With the Best UK Casinos
For all the new players, here’s a guide on how to sign up at an online casino.
First, pick an online casino that tickles your fancy.
You can select one from our top online casinos list. Hitting the “Play Here” button next to the casino of your choice will take you to that casino’s website. You’ll then be able to start the registration process.
In most cases, you’ll be taken straight to the registration form. If not, find the sign-up button, which is usually found at the top of the website on the menu on desktop. If you’re on mobile, then it should be right in the middle of your screen.
You will be asked to provide the following information:
- Full name (as seen on your ID)
- Email address
- Username (if necessary)
- Password
- Phone number
- Home address
- Date of birth
The registration form will look similar to this one below.
You will need to verify your email address in order to activate your account.
Make sure to check your spam if you haven’t received the welcome email in your inbox.
Select your preferred payment method.
Then, enter the amount that you want to deposit. It’s important to know the minimum amount that will release the welcome bonus.
After making your first deposit you probably would have received some free spins. These will be on a pre-selected slot game and will vary from casino to casino.
The introductory free spins are a good place to start your casino journey if you’ve never played before.
But, if you’re already an experienced player then search for your favourite game, and off you go!
Don’t be alarmed about the information that you have to provide, all your data will be securely stored. This is one of many requirements from the United Kingdom Gambling Commission.
Online casinos need to make sure that you are over 18 first of all. They also need to run affordability checks. This is all part of getting your account verified, and making sure you are who you say you are.
To verify your account you will have to send or upload a photo of your ID (passport or driving licence). Along with a proof of address, a letter statement within 3 months of the current date is required. This can be a utility bill or a bank statement. Speak to the casino’s support team if you need to share something else.
