How to Choose a UK High Payout Casino

So, what should you look out for if you are on the hunt for the best casino for payouts in the UK? Do all online casinos in the UK pay out the same, or are some just a little bit more generous than others? The following is what we look for if we are evaluating whether a casino qualifies as one of the best payout online casino sites UK players can play at. Just apply the same reasoning to your own research, and you shouldn’t go wrong.

1. High RTP/Low House Edge Games – The higher the RTP, or the lower the house edge, the more beneficial the games are to the player. Look for casinos that have plenty of slots with generous RTPs or casino games with low house edges, such as single-deck blackjack, video poker and baccarat without side bets.
2. Generous Bonuses and Promotions – All online casinos in the UK have the opportunity to be generous with their bonuses. Friendly bonuses have wagering set to around 35x or less and as few further T&Cs as possible. Look for unfathomable terms regarding bet limits, time limits and other limitations, as high payout casinos only provide fair bonuses.
3. Fast Withdrawal Times – The best paying online casinos in the UK don’t hesitate to get your money to you as quickly as possible. That’s because they want to treat you fairly and hope that you will recommend them to your friends who also enjoy playing at online casinos.
4. Fee-Free Withdrawals –  This aspect really goes hand-in-hand with the topic above. For all online casino transactions, the casino has to pay to use banking services such as Visa, PayPal and so on. While most online casinos – and definitely the highest paying UK online casino sites – are happy to absorb these fees, some pass them on to the customer requesting the withdrawal.  If you are looking for the best payout casino sites in the UK, then you can safely ignore any site that charges you to make a withdrawal.
5. Legal and Licensed – It goes without saying that you should never, ever play at any online casino that does not have a verifiable licence, or that claims to be ‘self-regulated’. Only licensed casinos are legally allowed to offer gambling services, so if a casino is operating without a licence, it’s not going to be one of the top 10 highest-paying online casino UK sites. If you are a UK resident, then it is best to play at a UK casino that has a proper licence from the United Kingdom Gambling Commission.

Understanding Payout Percentages

Let’s take a look at roulette. The best versions of roulette are versions where there’s a single ‘0’ on the wheel. If you bet on a single number, your odds of being correct are 36-1, yet you only get paid 35-1 if you are correct. This means a house edge of 1/37, or 2.7%.

It is therefore important that you understand payout percentages and only play games with a low house edge. The following is a list of the casino table games with low house edges:

You may ask yourself why casinos offer games with such low house edges. The answer is that in all the games above, decision-making is involved, and those house edges are only applicable if the correct decisions are made. As most casino players are not casino game experts, the actual house edge will be much better for the house than the figures posted above.

Slots and the Mystery of Return to Player

The house edge or RTP of casino table games can be easily calculated, but with slots, it’s a different story. When ascertaining the RTP of a slot, the software developer will run millions of tests in order to determine how the slot performs, hence gauging the RTP. They have to do this to make sure the slot is neither too generous nor not generous enough. Seasoned casino players won’t touch a slot if the RTP is declared to be 85%, and no software developer would dare release a slot with an RTP of 105% (as no casino would host such a generous slot).

One thing you can look out for at all of the highest-paying online casino sites is a list of games and RTPs. Many online casinos prove they have nothing to hide by being up front about the RTPs of their games, even though publishing this information is not legally required. It’s a sign of transparency, and also a sign that you’re likely to be treated fairly and with respect.

A Word About Volatility

You may have heard about volatility when it comes to slots and casino games, although it is more correctly applied to video slots. You may have heard about variance, too, which is a similar concept but slightly different.

Volatility is a measure of a slot’s unpredictability. A slot with low volatility pays out often, but with prizes around the same value as the spin fee. A slot with high volatility does not pay out as often, but when it does, it will pay out many times the value of the spin fee. It is important to understand what type of slot you are playing. If you want to grind away with plenty of losing spins in the hope of landing a big win, then a low volatility slot won’t be cutting the mustard for you. Similarly, if you want to slowly build a bankroll with a high percentage of winning spins, then you shouldn’t be playing a high volatility slot. Of course, there are medium volatility slots too, which give you the best of both worlds.

Variance determines how far away a slot could move from its average payout over a long playing session. A slot with low variance will payout roughly the same every time a winning spin is landed. A slot with high variance will payout big now and then, but will also reward ‘winning’ spins with payouts lower than the cost of a spin, coupled with a high number of spins that do not pay out at all.

As with volatility, you need to be playing slots with levels of variance that match your playing style, your bankroll and levels of patience. It’s also important to understand that volatility and variance do not have that much effect on a slot’s generosity – it’s the RTP of the slot that determines how ‘generous’ it is, not volatility and variance.

High RTP Games to Look Out For

So, which specific games at the best payout casinos in the UK should you look out for if you want to play with a low house edge? The following is a brief list of games, but please be aware that the low RTP only holds if you play these games skillfully, i.e. by using perfect strategy at blackjack, for example. If you don’t play these games as skillfully as possible, then the house edge won’t be as quoted. The good news here is that these games do not require days or even hours of study in order for them to be played in a way that is as beneficial to the player as possible.

Jackpot Blackjack (Concept Gaming) – RTP 99.94%

This hard-to-find blackjack variant has the lowest house edge at all, set as low as 0.06%. All the rules of this blackjack game are set in favour of the player, which is what makes it have such a low house edge. The key attribute is early surrender, which means you can surrender your hand for half your stake before the dealer checks for blackjack. This means you can recover half your stake if you’ve been dealt a bad hand (12 to 16) and the dealer is showing a ten, face card or ace, meaning the odds of you winning are stacked against you.

Single Deck Blackjack (Espresso Games) – RTP 99.85%

Any version of single deck blackjack will have a low house edge, but the version of single deck blackjack as devised by Espresso Games takes that low house edge a step further, lowering it to 0.15%. This is done by allowing ‘peeking’ – where the dealer peeks at their hand if they are showing a ten, face card or ace and then reveals their hand if they have blackjack. This is advantageous to the player as the player loses immediately, meaning they won’t lose more money via potential double downs and splits.

Craps (Any) – RTP 98.59%

The rules of the dice game craps are rigid so no matter the version of craps you play, the house edge will always be the same. The key to keeping the RTP low on craps is always to play the pass bet. This doubles your money if a 7 or 11 is thrown, and loses your stake if a 2, 3 or 12 is thrown. For all other totals, you double your money if the number is thrown before a 7 is thrown. There is also the odds bet where the actual RTP is zero! This, however, is a side bet you can only place after the dice has been thrown, and if you have already bet. You cannot bet on the odds without placing a main bet first.

Baccarat (Any – No Side Bets) – RTP 98.94%

Baccarat is a contest between the player and the banker. You, as the player, can bet on yourself winning, or the banker winning (you can also bet on a tie, but mathematically, it’s just not worth it). Betting on the banker every time gives a house edge of only 1.06%. If you want to render the house edge as low as possible, make sure you always bet on the banker. Remember that despite the use of playing cards, baccarat is basically betting on the flip of a coin.

Video Poker Deuces Wild (Mobilots) – RTP 100.76%

No, that is not a misprint. With Mobilot’s Deuces Wild Video Poker, the house edge is in the negative, which means the advantage is very much on the side of the player. Deuces Wild video poker is a version of draw poker in which all deuces (twos) are wild. If played with perfect strategy, the house edge is so low it’s negative! You may ask why a casino would offer a game with a negative house edge, and the answer is a simple one – because playing perfect strategy on this version of video poker is not easy! It can be done, though, making this (and Red Rake Gaming’s Number Bonus Video Poker) one of the few versions of a casino game at a best payout UK casino with a negative house edge.

Bonuses at the UK’s Best Payout Casinos

Bonuses can be hugely beneficial to players at the highest paying online casino UK sites, but only if players know how to get the best out of them. We’re here to help with bonuses, as we’ve seen more casino bonuses in our time than we’ve had Sunday lunches, so we can confidently claim to be online casino bonus experts.

The most common type of bonus is the matched deposit bonus. This will match your deposit with the same amount of bonus money between the minimum and maximum thresholds. Bonus money cannot be withdrawn – you can only use it to play online casino games at the site. Winnings should be yours to keep, although most of the time, you will have to complete wagering requirements before you are able to withdraw. Free spins work in much the same way – make a qualifying deposit and you get to play a number of free spins, usually on a specific slot. Most of the time, free spins are paid out as bonus money with wagering attached.

The Dreaded Wagering Requirements

Some people struggle with the concept of wagering requirements, but they aren’t too difficult to work out. Say the wagering requirement for a bonus is x30, and your bonus is £50. That means you are required to wager £1,500 of your own cash before you can cash out any winnings made via your bonus money.

You may immediately be wondering, what’s the point of spending £1,500 to gain £50? Well, wagering is not the same as spending. You could meet the wagering requirement with 750 x £2 spins on the popular NetEnt slot Starburst at one of the best payout online casinos in the UK. You will not lose every spin, and indeed, at the end of those spins, you could end up with more money than you started with. With a wagering requirement, the casino just expects you to risk some of your own cash in return for getting a bit of free moolah.

Other Terms and Conditions

Bonuses generally come swathed in terms and conditions. Below, we outline the most common T&Cs you’ll find attached to bonuses and free spins winnings, even at the best casino payout UK sites.

• Payment Restrictions – It is always best to check that your preferred payment method can be used to claim a bonus. Usually, only debit cards can be used to make bonus qualifying deposits. This is because online casinos think it’s too easy to open multiple eWallet accounts, for example, and claim the same bonus multiple times.
Top UK Casino Sites with the Best Payouts in 2025A bonus or free spins may come with a winnings cap. Once your bonus has been claimed and you’ve met any wagering requirements, if a bonus has a cap, then any money in excess of the cap amount is removed from your account.
• One at a Time – You should only be eligible for a single bonus at a time. If you have a current bonus and you attempt to claim a new one, then your current bonus will be removed, including any winnings from it.
• Game Contributions: – You may find that not all games contribute the same amount to the wagering requirement. If the contribution for blackjack, for example, is only 10%, then a £1 stake on a hand will only see £0.10 removed from your remaining wagering. This is why it’s always best to meet wagering requirements by using high RTP slots, as slots usually count 100%.
• Time Limits – Bonuses tend not to hang around forever. After signing up for an online casino, you will have a set time to claim your bonus, use it, and meet the wagering requirements. If you run out of time, then your bonus (and any winnings) will be forfeited.
• Bet Limits – When meeting wagering requirements, you’re likely to have minimum and maximum stake limits. If you place a bet outside of these limits while having an active bonus, then your bonus will be removed.
• Premature Withdrawal – You probably won’t be allowed to make any kind of withdrawal if you have an active bonus. If you do so, then bye-bye bonus!
• Fair wagering – Attempting to ‘game’ a casino while meeting wagering requirements by, for example, betting on black and red on roulette on the same spin, will be noticed. Such behaviour not only leads to bonus removal but also runs the risk of an account ban.

A you can see, there are plenty of T&Cs that even one of the top 10 highest paying online casino UK sites can add to a bonus. The obvious rule of thumb when it comes to bonuses is the fewer the number of T&Cs, the better!

Swift UK Deposits and Withdrawals

The best payout casino sites in the UK are happy to get your money to you quickly, as we have already discussed. The speed at which you are paid depends on which payment method you choose, though, as you’ll learn via the following information.

Debit Cards  – Cards directly linked to bank accounts are usually your best bet for speedy withdrawals. At the best payout casino UK sites, a debit card withdrawal may be processed within minutes and typically within four hours.

Credit Cards – You can’t use credit cards at UKGC-licensed sites, and we don’t recommend their usage at non-UKGC sites either. If you insist on using them, then withdrawals usually take three to five days.

eWallets – Ewallet withdrawals to the likes of PayPal, Skrill and Neteller can also be swift (under four hours), but the speed of the transaction is controlled by the casino itself, so waiting times of up to five days are possible too.

Bank transfers – Payments directly to banks have become speedier over the last couple of years as payments move away from the ancient BACS payment system. There is no guarantee of a swift withdrawal via a bank transfer, though, and timeframes up to seven days are common.

Cryptocurrencies – A quick reminder that UKGC-licensed casinos, even the best payout online casinos in the UK, do not accept cryptocurrencies. You should, though, be able to use crypto at non-UKGC licensed sites, and crypto withdrawals are usually instant or very fast indeed. Please remember that playing at non-UK casinos if you are a UK resident carries an element of risk.

Fees will also affect your payout, but the best payout casinos in the UK will not charge you for making a withdrawal. If you find you are being charged for withdrawals at an online casino, then it’s perhaps best to find an alternative, as you may repeatedly be giving up a percentage of your winnings for no reason.

We haven’t covered deposits in this short list, as all deposits – aside perhaps from a bank transfer – are usually instantaneous. Online casinos want your money as quickly as possible, but casinos that don’t qualify as the best payout online casino sites in the UK are not so quick to pay out!

A few deposit methods – Apple Pay, Google Pay, PaysafeCard and any ‘pay by mobile’ payment system – are not available for withdrawals. The table below provides a handy comparison of payment methods at online casinos in the UK.

If you are playing at a UKGC-licensed casino, then you can speed up the withdrawal process by submitting KYC (know your customer) documents as part of your registration process. Such documents (passport, driving licence, utility bill) are requested to positively identify you as a UK resident, and that you are who you say you are. This is a requirement of possessing a UKGC licence, but at some casinos may only be requested for large or frequent withdrawals.

How to Get the Most from a Best Payout Casino

Playing at one of the best payout casinos in the UK will be of benefit to you, but only if you approach your gambling in a suitable manner. Here are a few top tips from our online casinos experts that should help you do just that.

1. Choose High RTP Slots – It goes without saying that you should only play slots with decent RTPs, which means at least over 95%. Ignore the progressive jackpot slots as RTPs are low due to the size of the jackpot. Additionally, to win the full jackpot, you would have to play with the highest stake.

2. Play Slots with Suitable Volatility Levels – If you have a small bankroll, you’ll want to win little but often (low volatility), but if you have a decent bankroll, don’t mind churning away at the same slot for long periods and don’t mind completely exhausting your bankroll hoping for that big win, then you might want to raise the volatility.

3. Play Table Games with Low House Edges – Some casino games have such high house edges (we are looking at you, American roulette) that they are not worth playing if you want to actually win. Consult the list given earlier and choose table games with the lowest house edge.

4. Learn to Play Properly – If you are playing a game where decision-making is involved (blackjack or video poker, for example), then you only obtain those low house edges if you are making the correct decisions. There are plenty of resources around that will help you learn how to play these games optimally, to give yourself the best chance of winning.

5. Manage Your Bankroll – This is advisable whether you are playing at one of the best payout online casinos in the UK or not. Your bankroll is the amount of money you can comfortably afford to lose without it having any other effect on your finances. Once your bankroll for the day/week/month has been exhausted, walk away from the slots and tables until your next bankroll is available. Additionally, if you manage to double your bankroll during a session, take a break too. It’s better to spend the money you’ve won on other aspects of your life than on gambling.

Important Points to Note

It is always important to remember that playing at any of the top 10 highest-paying online casino UK sites does not guarantee winning money. If anyone ever actually found a sure-fire way to ‘break the bank’ at a casino, all casinos would close down overnight. Casinos are designed to take your money, not give it to you.

So, why play at the best payout casinos in the UK? Firstly, they can be entertaining, as long as you approach your gambling in the correct way. Secondly, by playing at casinos that have high RTP slots and low house edge table games, you’ll make your bankroll last longer. Finally, if you do happen to win, you’ll get your money swiftly and without any hassle. Just follow our tips to get the most from the best payout online casino UK sites.

Best Payout Casinos – Summary

If you are going to gamble online at casinos, and you are going to do it responsibly, then you really ought to be playing at the best payout online casino UK sites. They give you the best chance of winning, will allow you to maximise the lifespan of your bankroll, and will give you zero problems when it comes to cashing out.

Stick with the casinos on our top 10 highest paying online casino UK list and you’ll soon be getting the most out of your UK online casino play.
