A good payout casino is an online casino that has a high average return-to-player (RTP) rate across its collection of games. While the RTP rate can vary drastically from game to game, we recommend playing at GB casino brands with an average RTP of 96% or higher. According to our experts, these sites have the best payout rates in the UK, meaning you’ll get more money back.
The UK’s online casino highest payout sites will typically offer high withdrawal limits or no limits at all. This will attract high rollers, who often play high RTP games for large sums of money. We always recommend choosing brands with a maximum payout limit of £5,000 or above, as they make it easy to receive your winnings.
While a casino’s average RTP rate is important, it’s equally important to look at the RTP rate of each game you play, as it may be significantly lower than the casino’s average.
Jordan Conroy Editor
When calculating a casino’s payout rate, we take the RTP rate of every game available on the site and divide it by the number of games to get an average. We then rank the average RTP rate of each casino to find the sites offering the best payout rates in the UK.
For those of you who are unfamiliar with the term “RTP,” let’s break it down. A game’s return-to-player rate is the theoretical percentage of your bet that you’ll receive when playing each game. For example, if a game has a 97% RTP rate, on average you will receive £97 back for every £100 you bet.
Now, it’s important to remember that this figure is an average that’s calculated over tens, if not hundreds, of thousands of iterations. It doesn’t mean you will always receive £97 back when you bet £100. Sometimes you might receive more, sometimes you might receive less. However, if you play the game long enough, you will receive around 97% of your bet back.
When you play casino games with a low RTP rate, you theoretically lose more money each time you bet. For example, betting £1 on a 97% RTP game will lose you £0.03 per bet, whereas betting £1 on a 90% RTP game will lose you £0.10 per bet. Based on our research, a player’s bankroll will last longer when playing higher RTP games, as the casino’s edge is smaller and takes longer to become significant.
This is why players prefer to play at high-payout casinos. These sites have more high-RTP games, allowing for longer real-money casino gaming sessions.
The “house edge” is the advantage that the casino has in each game that it offers. The best way to think about the house edge is as the inverse of the RTP rate. For example, a game with a 97% RTP rate has a house edge of 3%, meaning that the casino profits an average of 3% every time you make a bet.
Remember, the house edge and RTP rates are just averages and do not guarantee a result.
A high-payout casino is an online casino that offers high withdrawal limits. An online casino with the highest payout limits appeals to high rollers, as these sites allow them to make large deposits and large withdrawals without hassle.
If you want to make large withdrawals, we at Gamblizard recommend choosing casinos that have a maximum withdrawal limit of £5,000 or more, perfect for players looking to play high-limit casino games.
At Gamblizard, we do the hard work, so you don’t have to. We take our reviewing process very seriously, and each casino is ranked with the help of a specially designed grading system. In such a way, only the best payout online casinos make it onto our list of recommendations. For more information on how we review the best payout casinos in the UK, check out our list below:

We test the payout limits of each payment method at the casino and only recommend sites that allow our readers to easily withdraw large sums.
We look for casinos with the best-value offers that can boost your bankroll. Key elements include low deposits, reasonable wagering requirements, and a high number of extra spins. Loyalty or VIP programs can also offer perks such as additional bonuses and higher withdrawal limits.
We expect top payout casino sites to provide 24/7 customer support through multiple channels such as live chat, email and social media. We will contact the support team to evaluate its response times, professionalism, problem-solving, friendliness, and knowledge.

RTP percentages can differ considerably depending on the type of game you play. The best-paying online casino sites will provide a variety of game types with higher RTP rates to boost their average payout percentage.
If you want to play the highest RTP games, then table and live dealer games such as blackjack and European roulette are your best options. They typically offer the smallest house edge in the casino, giving you a better chance of extending your gaming session.
Slot machines tend to have a wider spread of RTP ranges than table games, with some games having RTP rates in the 80s, whereas others push 99%. On average, slots have slightly lower payback percentages than table games but make up for the shortfall with innovative game features and potential jackpot prizes.
One game type that is often omitted from the best payout casino sites is bingo. This is due to its low payout rates, which average betweenf 70% and 85%. These games are typically found at dedicated bingo sites.
Here are some of the top casino games with the highest payout percentages:

The long-awaited sequel to the original cult classic from NetEnt not only boosts the game’s volatility from low to medium/high, but also nicely ramps up the maximum win.

Each online casino requires users to share their personal information upon signing up and completing KYC verification—something that not every player is comfortable with.
Casinos collect data from players for several reasons, including:
Casinos use the most modern security measures so that any data you submit is fully protected, and casino regulators require these sites to store and gather the data in a specific manner. You can learn more about how this is done in the casino’s “Privacy” section.
Here’s a mini step-by-step guide on how to withdraw winnings from our recommended sites:
The best online casinos generally offer players a range of payment methods to facilitate deposits and withdrawals. These include e-wallets, debit cards, prepayment vouchers and bank transfers. Some methods will allow for higher cashout limits and faster withdrawals.
In the UK, casino transactions are usually free. However, some may charge up to 3% commission or a fixed fee for each transaction, so it’s always advised to check the casino’s banking page or T&Cs for details. Even if the casino does not charge a fee, your payment provider or your bank may charge to process transactions, so make sure you check this as well before making a payment.
Below, we have listed those payment options with higher withdrawal limits, their potential fees, and average processing times:
| Payment Method | Deposit Limits | Withdrawal Limits | Fees (UK) | Processing Times |
|---|---|---|---|---|
| Visa | £1–£10,000 | £5–£5,000 | 0% (1-3% Commission) | 2–7 days |
| Mastercard | £1–£10,000 | £5–£5,000 | 0% (1-3% Commission) | 2–7 days |
| Skrill | £5–£10,000 | £10–£10,000 | 1.3%–2.99% | 0–2 days |
| Neteller | £5–£10,000 | £10–£10,000 | 2.99% | 0–2 days |
| Bank Transfer | £10–£100,000 | £10–£100,000 | 0–5% (or fixed fee of £5/£10) | 0–7 days |
As with everything in life, there are pros and cons to playing at the best payout online casino UK sites. Here are the most significant:
The best payout casinos offer a variety of games with higher-than-average RTP rates. With the help of the experts, Gamblizard provided a list of the top payout casinos for 2025, plus a helpful guide that you can use to find the best casino for your needs. Read through our unbiased reviews to learn more about the best payout casinos in the UK.
Casinos with the best payouts typically offer high RTP slots and low house edge table games. The more high RTP games offered by a casino, the better its payout rate, whereas a casino with a lot of low RTP games will have a poor payout rate.
The Return To Player (RTP) is a theoretical percentage that predicts the potential payout to players over an extended period of time. The formula for calculating house edge and RTP is simple, especially when you know the value of one of these parameters. RTP is calculated by subtracting the house edge from 100%; for example, a game with a 2% house edge has a 98% RTP rate.
The slots that have the best odds are the ones with the highest RTP rates. Having an RTP rate of more than 96% is above average for an online slot, and in our guide, we’ve provided a list of the top 10 slots with the best payouts; topping the bill with an exceptionally high 99% RTP is NetEnt’s Mega Joker.
According to our top 10 list, Mr Vegas is the casino with the highest payout rate for 2024 at 98.97%. Its game library offers slots, table games, and live dealer games with popular titles, including Caribbean Blackjack and Legacy of Dead.
A high-paying game is either a slot with a 96% or more return to player rate or a casino game featuring a low house edge. The best high-paying casino games include table games, live dealer tables or video poker games.
