How We Rate Our Online Casinos and Casino Offers
Welcome Bonus
We make sure that any site we list offers new players good value when it comes to their casino bonus offers, especially free money casinos no deposit required deals. We also factor in other elements, such as the wagering requirements, how long the bonus is valid for, etc. Casino deposit bonuses can vary quite a lot, what is the highest casino bonus won't always be the best for everyone, depending how your style matches up with the casino deals you're looking at.
Customer Support
Before we recommend a casino online, we need to be sure that it looks after its players properly, and so we only list sites that offer a variety of contact methods, such as live chat and toll free phone numbers.
Payment Methods
There isn’t much point playing at an online casino that doesn’t offer you convenient and accessible payment methods, or one where it takes too long to make deposits and withdrawals. We make sure that the sites we list have a range of payment options suitable for UK players, and that cash out times are reasonable and easy to complete.
Secure Gaming Environment
Everyone wants to play in a safe and secure environment where you can be sure the games are fair and that everything is being operated according to best practice. That’s why we only recommend online casinos that are licensed by the gaming authorities of the country they operate out of and are regulated by the UK Gambling Commission. Our listed sites are also tested and audited by independent agencies like eCogra or TST, so you know the games are fair, and you can enjoy spending a top casino bonus with peace of mind.
Game Quality and Variety
Even the best casino welcome bonus isn’t really worth much if the games aren’t up to scratch, so we only recommend casinos online who offer games by leading international producers like Microgaming, NetEnt and Playtech. We also make sure that our online casinos offer players plenty of variety in games and styles, and feature a wide range of online slots and casino games with bonuses so that you can be sure of never getting bored with the selection on offer.
Types of Casino Bonuses and Promotions
Our goal is to highlight the top online casino welcome bonus offers, covering the various types of promotions you’ll find at the sites we suggest.
This includes both initial bonuses for new players and ongoing deals for regulars after you’ve joined and started playing at any of our recommended online casinos.
Casino Deposit Bonus
At most of the sign-up bonus casino sites we endorse, new players get a match on their first deposit(s) as part of the package. Typically, this match is 100%, though it can sometimes be higher.
This is the go-to casino deposit bonus if you want to boost your bankroll significantly right from the start. Many of the best UK casino bonuses offer a match based on your initial deposit.
Online Casino No Deposit Bonus
With this type of free casino bonus, you receive free spins or cash to play with just for signing up with a new account. These spins might be limited to a specific game or, in some cases, usable on any of the site’s bonus-eligible casino games.
Keep in mind, though, that no deposit bonuses come with conditions - most commonly, you’ll need to make a deposit before you can keep playing with any winnings from those free spins.
This is especially true for any no-deposit free bet casino offer, which may still have wagering requirements.
Free Spin Bonus
More and more of the casino online sites that we recommend offer players generous free spin bonuses, either as part of a welcome casino bonus or as incentive for regular players. Most free spins are part of an online casino real money no deposit signup offer, where you can play a specific game before you add any money to your account, or they can also be part of a casino sign up bonus in addition to a match on your initial deposit(s). You also get the chance to win free spins when new slots are released, or as part of a holiday or big sporting event. Check out our casino free spins page for all the latest casino free spins offers.
Refer-a-Friend Bonus
Once you’ve signed up for an account, another top online casino bonus you can enjoy is the Refer-a-Friend bonus, where if you recommend someone to the online casino (usually by email), and they then sign up and make a first deposit, you both receive a casino bonus, usually cash or free spins, and this can be worth in the region of £50.
Reload Bonus
One of the best casino bonuses slots players can enjoy is the reload bonus, where on a given day (usually either once a week or once a month), any deposit you make on that day will receive a match bonus, generally worth between 10% – 25%. It’s often the case that if you play on a particular game once you’ve reloaded, you get awarded additional free spins as well.
High Roller and VIP Bonuses
Online casinos work hard at keeping your loyalty once you’ve signed up, and so regular players can also benefit from high roller and VIP bonuses. Most of the casino bonuses UK players enjoy come from these sort of incentive schemes, many of which are invitation only, and the benefits can include free spins, deposit match bonuses, faster withdrawal times and higher limits.
Daily and Weekly Special Bonuses
Once you’ve signed up for a welcome casino bonus, the offers don’t stop there as the sites we recommend like to incentivise players with plenty of daily and weekly casino bonus offers as well. These will usually be emailed to you, or sent via SMS, so keep an eye on your in-box to take advantage of the latest top online casino bonus deals. Finding this kind of existing customer deal will make the top casino bonus go even further, and can really enhance your gaming experience.
Mobile Casino Bonuses
At most of the sites that we recommend, new players can benefit from the same sign up bonus casino deals if they register via the desktop or mobile casino sites, although with some casino apps there are extra incentives and casino welcome bonus deals for those who sign up initially via the mobile casino. if you plan to play on a mobile device, before you sign up, just check to see if there's an online casino sign up bonus that's exclusive to mobile, if there is, it's likely to be bigger.
How to Choose the Best Casino Offers
Finding the best casino bonus isn’t easy, there’s plenty out there to choose from, as almost every brand now offers casino welcome bonuses to new players.
The key is getting the right casino sign up bonus for you and your type of gaming.
Below are some areas to consider when looking for first deposit bonuses.
What Games Do You Play?
With modern casino games looking as good as ever, the choice is fantastic for punters.
We all have our favourites, but some online casino bonuses are limited to the type of game you can play with your welcome bonus.
This could mean your bonus is free spins, so has to be used on slot games, or alternatively, cannot be used on live casino games, as an example.
Make sure, whether you play slot games or something else, the UK casino bonuses you claim can be spent on the games you want to play.
What is Your Budget?
Think about your budget and if you need to search out a low deposit bonus and a site that have further low minimum deposit requirements for players.
A big welcome bonus is great, but if you’re only making a small deposit, you won’t be able to claim the full deposit bonus, only part of it.
Online casino bonuses come in all kinds of sizes now, allowing you to get the best bonus money for your budget, so shop around and find an initial deposit size you are comfortable with.
What Payment Method Do You Want to Use?
We all have a preferred payment method, and you should always check that the site accepts this method before signing up.
But also look at the terms on a casino bonus, in particular any deposit bonuses you see. Make sure your payment method is valid for this, so you can deposit in the usual way, and claim the welcome bonus.
Some welcome bonuses will have rules around what payment methods are valid for the bonus, and if yours is not valid, you will not receive the deposit offer.

However, the points below cover this as a quick overview, to give you an understanding of the areas we focus on.
- Security and trust is our biggest factor, we only want the safest and most secure sites for you to play on
- Payment methods are next, ensuring you are comfortable when making a deposit or withdrawal

Legislation and Safety
Safety online is important. And it couldn’t be any more important to us.
That’s why we only work with the most trusted safe online betting sites and online casinos and make sure both they and us follow every law, regulation and rule to the letter.
All payments with our favoured bookmakers are secure and each and all follow the relevant laws and hold the relevant license coinciding with relevant Gambling Commission.
How To Play Online Casino
Playing online is as easy as sitting in a casino room and pulling the arm of a fruit machine down yourself.
Our reviews of the top online casinos will give you a rundown of everything you need to know when it comes to playing online casinos, while you’ll also be walked through the best sign up offers and promotions.
Within our online casino reviews and on the casinos’ site itself you’ll find the basic rules of casino games as well as walkthroughs and trials/free plays to get to grips with the game.
How to Cash Out Winnings
If you’ve struck lucky and you want to cash out, it’s always relatively easy to do.
Naturally, our online casino reviews will give you the lowdown on how to withdraw your funds on a casino by casino basis, but more often than not all you’ll have to do is go to your account page and find the Withdrawal section.
You can generally withdraw via most methods and in some cases may take up to three days for your winnings to appear in your bank.
However, if you’ve won with a free bet there may have to play a certain amount of games before you can cash out. It’s well worth checking our online casino reviews, where we highlight all the major and minor terms and conditions.
