We’ll show you how we review casinos, what kinds of bonuses you can earn, and how to take full advantage of these promotions. Read on to learn everything you need to know to get a great casino bonus in CA!

How We Rate and Review UK Online Casino Bonuses

Our thorough approach is the secret to our detailed review process. We don’t just look at the size and terms of a bonus and give you that information. Instead, we do a deep dive on everything in each casino to make sure both the bonus and the site are up to our standards.

We choose the best online casinos only after testing every aspect of each site. If a casino falls short in an area like customer support or reputation, we won’t recommend them to you no matter how tempting their bonus may be. Below, you can see some of the most important areas we consider when we choose our top casino bonuses. 

We Join Every UK Online Casino

We would never tell you to join an online casino that we haven’t tried ourselves. Our team registers for every casino site in United Kingdom as a part of our standard review process. This allows us to make sure the sign-up process goes smoothly, and that we can give you step-by-step instructions on how to start playing at each site.

We Assess the Casino’s Reputation

One of the most important steps we take is researching the history and reputation of each casino. This allows us to find out of there have been problems at a site before, and if you can trust the site to provide you with quality service in the future.

Even if a site promises the best casino bonus in UK, that’s not worth anything if players report problems getting their money, unresponsive customer service, or faulty software. By looking into the reputations of United Kingdom casinos, we ensure that you’ll only play with trustworthy, reputable operators.

We Claim the Welcome Bonus

One of the first things we do after opening an account at each site is take the casino welcome bonus. This gives us some immediate insight into how each casino’s bonus and promotional systems work.

When we take these bonuses, we dig deep into the terms and conditions to make sure players are treated fairly. It’s important not only that casinos state fair rules for their bonus offers, but that they follow those same terms. We also evaluate how quickly and accurately bonuses are awarded. The best sites also let you know as soon as you’ve cleared a bonus, and keep you updated on your progress as you try to meet wagering requirements.

We Deposit Using Our Own Funds

It’s hard to enjoy real money casino play if you can’t reliably make deposits into a site. Our top casinos offer a solid mix of deposit options that allow you to get in on the action no matter what resources you have available.

Our reviews dig into the variety of deposit methods available, as well as the speed at which funds hit your account. We also want the deposit system to be simple and straightforward, as a frustrating deposit experience can ruin your time at an online casino.

We Test the Wagering Requirements

Many players evaluate casino bonuses based on the size of a matching offer, the number of free spins, or the maximum value of the promotion. However, there’s another important aspect to consider: the wagering requirements, which dictate how much you must bet before you can cash out any bonus winnings.

We look at the playthrough requirements of each and every casino bonus in UK before we recommend any offers to you. Of course, lower requirements are usually better, but that’s not all we consider. We also look at the games you’re allowed to play and how much they contribute, so you have a full picture of what’s expected of you when you take a bonus.

We Test Ease of Withdrawals

Nobody wants to have to wait to enjoy their winnings. But some otherwise good online casinos subject players to long delays every time they try to cash out. That’s why we always make withdrawals at each online casino that we review. 

We try to cash out via a few different methods to see how various options compare in terms of speed and ease. We’ll also let you know whether initial processing times are reasonable, and how easy it is to follow along as your cash out progresses.

We Contact Customer Support Agents

Every good casino needs an excellent customer service team behind it. Most players will need help from time to time, whether it is asking about the details of a promotion, reporting a software issue, or asking questions about a deposit or withdrawal.

Our team talks to customer support at every site we recommend. We want agents to be both courteous and knowledgeable. They should also respond to your questions promptly. You should be able to contact customer service 24/7, whether that’s by email, phone, or live chat.

How to Find the Best Casino Bonuses in UK

If you’re looking to claim the best online casino sign up bonuses, then you’re in the right place. You can find all the top casino bonuses in UK right here on our site, with convenient links that allow you to go straight to the best sites in the country and get their top welcome offers.

We take the time to inspect each bonus offer to make sure it’s a good deal for you. When you look at our recommendations, you won’t find any bonuses that feature impossible wagering requirements or unfair restrictions. In addition, we only show you bonus offers from reliable and trustworthy sites so that you can concentrate on playing rather than worrying about whether you can withdraw your winnings.

Types of Casino Bonuses

You may know that you want some sort of bonus when you sign up for a new casino, but you may not realize just how many types of casino bonus offers there are in United Kingdom today. Every casino gives out different promotions not just in terms of how much money they offer, but also how those bonuses work and what you need to do to claim them.

Before you take any of these bonuses, you should understand how each one works. Here’s a breakdown of every common bonus type you’ll encounter while playing at UK casinos.

Casino Deposit Bonus

Most offers that you’ll see when playing at our top sites are casino deposit bonuses. This refers to any bonus that you get as an added benefit when you put money into a site. These tend to be more generous than no-deposit bonuses, as casinos want to reward you for putting money into your account. Below, you’ll see many examples of casino deposit bonuses, along with examples of each type.

Welcome Bonus

A welcome bonus is any casino bonus offered to new players for signing up, or for making their first deposit. For instance, if a casino offers you 50 free spins on a popular Slot if you deposit at least $50, then that would be a welcome bonus.

This is a fairly general category. A welcome bonus can come in many varieties, which we break down in more detail in the casino bonus areas below.

Match Bonus

A matching bonus is any offer from a casino that gives you bonus funds based on the amount you deposit. Typically, casino bonuses like these are advertised in terms such as a 50% match up to $500. In that case, you would get £1 in bonus money for every $2 you deposited, up to a maximum of $500 in bonus funds. We’ve broken down some of the money common match bonuses below.

100% Deposit Bonus

A 100% deposit bonus is the classic casino bonus, which you’ll find at many of our top sites. For every dollar you deposit, you’ll be given a dollar in bonus money to play with. For instance, if you get a 100% matching bonus up to $250, then you can deposit $250 and receive another $250 to use on your favourite Slots. Tons of UK online casinos offer a 100% matching bonus, so you’ll see this at many of our recommended sites.

200% Deposit Bonus

A 200% deposit bonus ramps up the rewards by giving you double your deposit in bonus money. For instance, If you have a 200% matching bonus with a maximum reward of $500, then you could deposit just $250 to get the full $500 bonus.

300% Deposit Bonus

At the 300% deposit bonus level, you’ll start to get extreme amounts of funds for your deposit. For instance, you may deposit just $100, but get a bonus of $300 in funds. At this level of matching casino bonus, the terms and conditions become even more important to look at than normal, however. Some casinos may put heavy restrictions on your bonus funds in exchange for this generous match percentage.

400% Deposit Bonus

Yes, you can even get a 400% deposit bonus at some of our recommended UK casino sites! These bonus offers give you the most value for your money. For instance, if a casino offers you a 400% match up to $800, you only need to deposit $200 to get the full $800 in bonus funds – or $1,000 in total to play with. Again, as with all big bonus offers, it’s important to read the terms and conditions to understand what you need to do to get the most out of these promotions.

£10 Deposit Bonus

We love casinos that don’t ask you to make huge deposits in order to start playing. A £10 deposit bonus is just what it sounds like: you can deposit just $10, and still get a bonus from the casino to allow you to play a bit more. These are great offers for low-stakes players who just want to get some real money play in without risking much of their money.

$500 First Deposit Bonus

We’ve found that many of the best casino bonuses in UK are bonuses related to depositing $500. These $500 first deposit bonus offers allow you to get not only matching bonus funds, but also additional rewards like free spins. If you’re willing to put $500 into your account, then you can often get the maximum reward for casino bonuses at UK sites.

Cashback Bonus

While we all want to win, sometimes luck doesn’t go our way. That’s where cashback bonuses come in. In these offers, you’ll get a percentage of your losses on a regular basis, often weekly. For instance, imagine a casino offers you a 15% cashback bonus. You play Slots that week, losing $200. You’ll get 15% of that amount – or $30 – back as a bonus.

Casino Reload Bonus

We’ve mostly talked about welcome offers to this point, but don’t worry: the bonuses don’t stop there. Casino reload bonuses are rewards that sites offer you for adding more money to your account. These are usually announced via the front page or in a promotions area on the casino site, and you may also get emails alerting you to the latest offers. While these casino bonuses are usually not as valuable as welcome bonus offers, they provide you with extra value when you’re thinking about topping up your account.

No Deposit Bonus

Some of our favourite casino bonuses in UK don’t require you to make a deposit at all. These nodeposit bonuses give you some money to play with on real money games, without asking you to risk a single dollar to do it. For instance, a casino might offer up $25 in a no-deposit bonus. Just by signing up, you can use that $25 in the casino.

These bonuses tend to be fairly small when compared to deposit match bonuses. In addition, it’s important to read the terms and conditions. You will likely be limited in how much you can win from these promotions, and the playthrough requirements may be strict. However, nodeposit bonus offers are still a great way to try a casino without risking any money of your own.

Free Spins

Not all bonuses are awarded directly in dollars. A free spins offer gives you the chance to play one of the top Slots at a casino at no cost. You get to keep the winnings, though you will likely need to complete a playthrough requirement before you can cash out any of that money.

For instance, a casino might give out a bonus that offers you 50 free spins on the Starburst Slot just for making a first deposit of any size. You can take your 50 spins at the specified stake, then treat the winnings as bonus funds.

High Roller Bonus

Casinos love to attract high rollers, and save their most generous offers for them. High roller bonuses are designed specifically for those who want to make big deposits, and feature a variety of different benefits for players who qualify for them.

For instance, a high roller bonus might allow you to get a 100% bonus worth up to $2,500 – perhaps a lower percentage match than the standard bonus, but a much higher maximum award. You may also et to play a greater variety of games to clear the bonus, have a lower playthrough requirement, or otherwise enjoy better terms and conditions as a high roller.

How to Claim a Casino Bonus

Claiming a casino bonus is an easy process. But if you’ve never tried to collect a bonus before, you might be a bit confused bout how to make sure you get your rewards. That’s why we’ve created the following step-by-step guide. Read on to learn how to make sure you can take full advantage of the best casino bonuses online today.

Step 1: Choose a Casino Bonus

First, pick one of our top bonus offers from this page. Take your time and find one that’s just right for you. Then, click through our link to head right over to the casino site. If we mention any casino bonus codes related to the promotion you want to grab, be sure to note them. However, keep in mind that you won’t need a code for many of our top bonuses.

Step 2: Register Your Account

At the casino, fill out the form to open your new account. Most sites will ask you for the same basic information, such as your name, address, and email. You may also choose a username and password for the site at this point. If the site asks for a bonus code, you can use the one we provided you here.

Step 3: Make a Real Money Deposit

Many casino bonuses in UK require you to make a deposit to claim them. To do so, visit the casino’s cashier page. There, you will find a list of available deposit methods, such as credit cards, cryptocurrency, e-wallets or other options.

Pick a method that works for you. Input the required information, and let the casino know how much you would like to deposit. Once again, if the site asks for a casino bonus code at this time, you can input the one we’ve provided for you. Confirm your deposit, and in a matter of moments you’ll see your money credited to your casino balance.

Step 4: Play Your Favourite Games

Now it’s time to get your play in so you can collect your bonus! Head into the casino and find the Slots, blackjack, roulette, or other games you’d like to play. Be sure to understand the terms and conditions of your bonus before you start playing so that you know which games you are allowed to play, and how much each game will contribute to clearing your bonus.

Step 5: Clear Your Bonus

Once you’ve completed the wagering requirements related to your bonus, the site will release your winnings and/or remaining bonus funds to you. Congratulations: you’ve claimed your first casino bonus!

Casino Bonus Wagering Requirements

One of the most important factors to consider when you take a bonus is the wagering requirement. The wagering requirement is the amount you must bet before you clear the bonus, at which point you can cash out your earnings from the promotion.

While wagering requirements vary greatly between sites (and even between bonus offers at the same casino), they are usually expressed as a multiple of the combined amount of your bonus and your deposit amount. This isn’t always the case, though, so read our reviews or check the terms and conditions to understand exactly what the wagering requirements are on your casino bonus.

For instance, you may see a bonus with a wagering requirement of 50x your combined deposit and bonus amount. If you deposit $100, and get a $100 bonus, that’s $200 in total. Fifty times that amount is $10,000. That means you must make $10,000 in bets in order to clear your bonus.

Evaluating Wagering Requirements

In order to know if a bonus is worth taking, you’ll need to look at the playthrough requirement and make sure it is reasonable for your play. Generally speaking, the lower the wagering requirement, the better, and it can make a world of difference in how realistic it is for you to clear the bonus. That’s especially true if you only have a limited amount of time to finish your play, with a week being a common timeframe.

For instance, imagine you get a solid casino bonus that gives you a 100% matching bonus up to $200, with a wagering requirement of 25x. You deposit $200 to get the full $200 bonus. That means your playthrough requirement is $10,000 (or 25 x $400). If you like playing Slots for £10 a spin, you only need to make 1,000 spins to finish the bonus – a very reasonable amount over the course of a week.

On the other hand, another casino might try to tempt you with a 400% matching bonus of up to $400 – but one that has an unreasonable 100x turnover requirement. If you make a $100 deposit and get a $400 bonus, you will have to play $50,000 (100 x $500) worth of Slots to finish off your bonus, something you’ll likely struggle to do at fairly low stakes.

Casino Bonus Terms and Conditions Explained

Nobody enjoys wading through the terms and conditions of a casino bonus. But while much of what’s included in these regulations is legalese that you might not need to read, there are some important points you should look for before you accept a bonus offer. Read on below to learn about some of the most important terms and conditions you’ll want to look for before taking a bonus.

Maximum Win

While these were once rare, maximum win amounts are becoming a more commonplace condition of online casino sign up bonuses. These rules dictate the maximum amount that you can cash out from a bonus, no matter how much you actually win at the casino during your bonus period.

These are most common (and most understandable) on no deposit bonuses, as you aren’t risking any of your own money. For instance, a bonus that gives you £10 free without a deposit may have a maximum win of $100. Unfortunately, even some deposit match bonuses now come with these win limits.

One bright spot is that progressive jackpots are often exempt from these limits. If you play a Slot and hit the grand jackpot, chances are you’ll still be able to take home the full amount, no matter what the maximum win is on your bonus.

Minimum Deposit

We’ve talked a lot about maximum bonus amounts, but many offers also come with a minimum deposit you need to make in order to claim the promotion. This can be larger than the minimum deposit for the casino. For instance, a casino bonus in UK might say you must deposit $100 to take advantage of it – even if you can deposit a minimum of $25 to play on the site. Be sure to know what the minimum deposit for your bonus is before you put money into your casino.

Payment Method Restrictions

Payment restrictions for casino promotions can work in two different ways. In some cases, there are bonuses tied to using a specific payment method. For instance, you may get a special bonus only if you deposit using Neteller, one that isn’t available for any other deposits.

However, you can also run into bonuses that come with restrictions that aren’t so clear. For instance, a casino might state in its terms and conditions that you can’t use certain deposit options like wire transfers or credit cards to take a bonus offer. If you see a restriction for a promotion that impacts the way you want to deposit, it might be best to find another casino bonus that can be accessed with your chosen method.

Time Limit

Even the best casino bonuses won’t allow you to play forever. Virtually all bonus offers come with a time limit that dictates when you have to finish your playthrough requirement or meet other terms of the promotion. These time limits can vary, but a week or a month are typical periods.

If you fail to finish clearly your bonus by the end of the time limit, you won’t get the full benefits of the promotion. In some cases, you may immediately lose all of your bonus funds, and potentially forfeit any winnings you’ve made while attempting to clear your bonus. In other cases, you may get to keep the portion of the bonus you’ve cleared, but won’t be able to continue clearing those funds.

Game Limits

Another area of casino bonuses that you should consider is game limits, which tell you what games you can play to clear a bonus. Almost all bonuses allow you to play Slots, keno, and scratch ticket games. However, blackjack, craps, video poker and roulette may be off limits for some bonuses.

Even if those game are allowed, they may not contribute to clearing the bonus in the game way. For instance, many casinos only allow a percentage of each bet on certain games – such a blackjack – to count to towards your wagering requirement. If you play a £10 hand of blackjack, but it only contributes at a 10% rate, that means you’ve only cleared £1 of your playthrough requirement.

Betting Limits

When clearing a bonus, you may want to be careful about how you bet in the casino. Almost all sites include some rules that dictate how you can bet, even if these won’t impact most normal play.

For instance, a common condition is that the site can void your bonus if you engage in behaviour meant to eliminate much of your risk. A common example is betting on both red and black at the same time on roulette.

You won’t have to worry about that sort of rule if you plan on playing Slots. However, your casino might have rules on maximum bets while clearing your bonus. For instance, you might not be able to make a single bet over $100, or you may not be allowed to wager a significant percentage of the wagering requirement on a single hand or spin. These rules vary significantly, and often leave room for the casino to determine what constitutes abusive behaviour.

How Casino Bonus Codes Work

In some cases, a casino might ask you for a bonus code in order to claim a promotion. While this might seem like a nuisance, these can actually come in handy, as they give you the option of choosing between bonuses, or even to not take a bonus at all.

If a casino requires a bonus code, we will always mention it in our information on that casino and its promotional offers. A code is usually a short mix of letters and/or numbers. For instance, we might tell you that using the code CA100 might allow you to claim a 100% matching bonus at one of our top UK casino sites.

To claim this offer, you would input the casino bonus code when asked for it by the gambling site. Typically, the casino will ask you for this code when you make your deposit. You can look for a line that says “if you have a code, please enter it here,” or something similar. You might also get this prompt when you first register your account, especially for a no deposit bonus. Either way, simply input the code we’ve provided for you when prompted, and you’ll be eligible for the associated bonus offer.

We mentioned before that you might choose not to use a bonus code. While casino bonuses are great, you may know that you can’t meet the wagering requirement or other terms and conditions. You might also want to play games that aren’t allowed under that particular bonus. In those cases, it’s perfectly okay to just sign up for the casino and make a deposit without taking the bonus so that you don’t have to worry about the restrictions that come with it.

Live Casino Bonus

Live casino games are an exciting way to get the real-world gaming experience on your computer or phone. However, it can be a bit harder to find the best live casino bonuses, as many sites don’t offer much in the way of promotions for these live dealer games.

In some cases, casinos may treat live casino games just like other table games. That means you may not be able to play games like live blackjack or live roulette while clearing a bonus. In other cases, the casino will allow you to play live dealer games, but the contribution levels will be very low.

That said, there are some great live casino bonuses out there. We’ve included many of these among our top casino bonus sites for United Kingdom, and you can find even more information on our live casino page.

Mobile Casino Bonus

If you’re planning on playing at online casinos from your phone or tablet, then you might be interested in getting a mobile-specific casino bonus. These offers give you a special bonus for signing up or depositing on a site’s mobile app or in your device’s web browser.

Often, you won’t even have to do all of your play on your mobile in order to take full advantage of these bonuses – but you might want to. Mobile casinos offer all of the same great games and features as you’d get when playing on your desktop or laptop. However, you can access these games from the convenience of your phone or any other device, meaning you can play anytime, anywhere, whenever the mood strikes you.

Casino Bonus Strategies

There’s no single casino bonus strategy that’s perfect for every promotion. However, there are many ways you can try to improve your odds when you take one of these offers. Here’s a look at a few of our favourite casino bonus strategies that you might want to implement.

Doubling Up: In order to use this strategy – also known as the Martingale – you’ll want to be clearing a casino bonus that doesn’t have a maximum bet limit. If there is a limit, but larger bets simply don’t count towards clearing the bonus, this strategy is available, though at a higher risk. If bets that are too large can void your bonus, then you shouldn’t try this.

Here’s an example of how this works. If you receive a matching bonus, you can wager the entire match on something that’s nearly a 50/50 bet, such as red or black on a single spin of roulette. Should you win, you’ll have doubled your bonus funds, giving you a much better chance of clearing the bonus. While this is high risk, as you could lose your deposit quickly, you’ll greatly increase your chances of taking home significant winnings as well, making this one of the best ways to improve the value of a matching bonus.

Play High RTP Slots: This strategy won’t necessarily make you a winner, but it’s a great way to get through the wagering requirements of a casino bonus. By sticking with Slots that have a high return to player (RTP), you’ll improve your theoretical return, and have a better chance to keep some of your bonus funds.

Some of the Slots with the highest payout are UggaBugga by Playtech (99.07%), Mega Joker by Netent (99%) and Rainbow Riches Pick n Mix by Barcrest (98%). Be aware that some game providers will let the operator choose between different payout percentages. For example, a machine on one website might pay out 97%, but on another website the exact same machine will only pay out 93%. It’s often difficult for a player to know what payout percentages an online casino has chosen.If you want to be entirely safe, we suggest avoiding Slots from Play N Go, as they are known to offer this option to operators.

Play High Volatility Slots: If you’d like the chance to hit a big score with your bonus the best way to go is to play high volatility Slots. Since these machines are more likely to pay out big prizes, there’s a chance that you could quickly lock in a profit and be certain that you’ll be able to meet your wagering requirement. Some highly volatile Slotsinclude Dead or Alive 2, Dead or Alive, Book of Ra, Extra Chilli and Bonanza.

Look for a New Casino: Newer casinos often offer the most attractive bonuses as they want to attract players to quickly grow a base of users. However, it’s important to be careful and only stick with our recommended casino bonus sites. There are some unreliable sites that may spring up quickly and disappear nearly as fast. Make sure that any casinos you play at operate with a proper gaming license, and carefully read the terms and conditions of any bonus offers.
