Best Payout Casinos in the UK | Highest Paying Online Casinos

Looking to increase your odds of winning a payout at UK online casinos? Consider joining the best payout casino sites. Playing at these casinos can help you win more often due to their higher payout rates and reliable payments. 

On this page, we’ll compare several gambling brands to help you handpick the best payout casino in the UK. You’ll also understand how the casino payout rates work and our proven tips to increase your odds of winning cash. 

What are High Payout UK Casinos? 

High payout casinos are online casinos that give players better returns through games with higher RTP (Return to Player) rates. RTP is the percentage that shows how much money a game pays back to players over time. Since every game has its own RTP, choosing casinos with higher average rates means you stand a better chance of winning more often.

For instance, a slot game can have a 96.30% RTP. It means the highest amount you can win from every £100 wager is £96.30 in the long term. Therefore, a higher percentage automatically increases your chances of winning a payout. 

With that in mind, a high payout casino is a gaming site that offers an average RTP value of 96%. You can calculate this rate by determining the average RTP of all games or the average of total winnings divided by losses. eCOGRA often provides game testing certificates with the average RTP. 

How to Understand Casino Payout Rates

Payout rates (or RTP – Return to Player) show you how much a slot game pays back to players over the long term. Think of it as an average guide, not a guarantee on every spin.

For example, let’s take Blood Suckers Megaways at bet365, which has an RTP of 97.66%. That means, if you wager £100 on this slot, the game is designed to pay back around £97.66 over time, while the remaining £2.34 is the casino’s edge.

Of course, you might win £500 on your first spin or nothing at all after £20 – that’s variance. But the RTP percentage is still useful because it shows which games give you the best long-term chances.

When you look at casino averages, like bet365’s 98% payout rate or Spin & Win’s 96.97%, it tells you that across thousands of games, these sites return most of what players stake. The higher the number, the better your chances of keeping your bankroll going while still having fun.

There are many factors we look at when reviewing payout casinos, but to keep things clear, we’ve focused on the five most important ones. These are the key areas that truly show which UK casinos pay out the best:

UKGC Licensing

Only casinos with valid permits from the Gambling Commission make it to our list. We head down to the casino’s footer section to find and verify the licensing details. As you may know, the Commission ensures the casino adheres to the highest regulatory standards in the UK. 

Game Testing 

Another certificate that we look for is game testing approvals. The best payout casinos in the UK undergo rigorous RNG tests by third-party laboratories like eCOGRA and iTech Labs. This certification proves that the casino provides fair and transparent gaming services. 

Game Payout Rates

A casino with a dynamic variety of games is definitely an exciting option. However, we go further to discover if the casino offers games with the highest payout rates. bet365 does it even better by allowing players to filter the library by RTP ranges. 

Game Providers

The best payout UK casinos only collaborate with legal and reputable software providers. We only rate casinos with games from industry trailblazers like Games Global, NetEnt, Play’n GO, Playtech, and IGT. Some of these companies offer the highest payout rates in the iGaming scene.

Withdrawal Speeds

A high payout casino is just as good as the withdrawal services. We play at each casino and cash out winnings to test the withdrawal times. Our highlighted casinos can process payouts within minutes or hours, depending on your chosen brand.

Highest RTP Games in the UK

Most casino games have reasonably high payout rates. However, some game variants have lower payout rates, which can limit your payout chances. Remember, the industry standard these days is 96%. Below are the highest payout casino games to play in the UK:

• Poker: Some Poker variations can provide more than 100% RTP with an optimal strategy. Deuces Wild (100.76%) and Double Bonus (100.17%) are excellent examples. 
• Blackjack: This card game lets you increase the RTP when using a strategy. Most Blackjack titles can provide payout rates exceeding 99.50%. 
• Baccarat: Baccarat games can pay out reasonably well when betting on the Banker and Player bets. The Banker bet is the most rewarding, providing a 98.94% RTP.
• Craps: In Craps, the Don’t Pass and Don’t Come bets have an RTP value of 98.64%. You can also enjoy a 98.59% RTP with the Pass Line and Come bets.

8 Practical Tips for Playing (and Winning) at High RTP Casinos

Choosing a casino with the highest RTP values doesn’t guarantee winning. Still, you can use some secret tips to maximise your time at these casinos. Follow these tips:

• Play High RTP Games: Casino games have varying RTP rates, as the software developer indicates. Therefore, only play games that promise the highest payout rates in the long term. So, choose slots with RTP over 96%.
• Consider the Volatility: This point applies to games like slots and Slingo. Play titles with low or medium volatility ratings to increase your chances of winning more often. Highly volatile slots can pay out decent winnings but less frequently. If you’re casual, go for low-volatility games like Ugga Bugga (small wins, frequent).
• Use Casino Bonuses: Maximise casino bonuses like free spins and bonus cash to play high RTP games. These rewards can protect your bankroll and let you win a payout if you fulfil the wagering requirement. Sites like bet365 Games give up to 500 free spins on branded and exclusive slots. That’s a lot of free play before dipping into your own cash.
• Use Betting Strategies: Betting strategies like Martingale and Fibonacci can be your ticket to success, especially in Roulette, Baccarat, and Blackjack. These strategies can help you maximise your bankroll. 
• Practice Bankroll Management: Most importantly, set aside money to play at the best payout casinos. Gambling can be unpredictable most of the time.
• Try different genres: Don’t just stick to Egypt or Fishing themes. Try branded slots like Who Wants to Be a Millionaire Megaways or quirky titles like Jokerizer. Fresh features (scatter pays, cluster wins, cascading reels) keep things exciting.
• Mix classic and modern slots: Retro titles like Mega Joker (99% RTP) are great for steady play. But modern video slots with Megaways or Power Reels add variety and entertainment.
• Always check wagering terms: Free spins and bonuses often come with playthrough requirements. A “100 free spins” offer may need 35x wagering before you can withdraw any cash.

There you have it! Now you know the UK casino brands with the highest payout rates. Although the payout rates are long-term estimates, you can get more value by playing at these casinos. Still, drop any high expectations of winning a payout. High payout rates don’t guarantee wins!
