Casino payouts typically factor in concepts like RTPs, wagering requirements, hefty jackpot amounts, withdrawal limits, and withdrawal processing times. A 96% RTP hints at a game’s theoretical return over time, a million-pound jackpot tells you a game or tournament's prize potential, and withdrawal limits and processing times help with managing expectations. So, check these before choosing a casino.
Quick best payout casinos FAQs
The best paying casinos in the UK offer high RTPs and huge jackpots.
Some of the highest paying casinos include bet365, BetMGM, and Betfred.
Popular high-RTP slots on high-paying casinos include Pirots 5 and Legacy of Dead.
Consider jackpots, RTPs, and cashout limits when choosing online casinos.
What are the best paying casinos in the UK?
It depends on what you mean by a best payout casino. When most players say “high payout”, they’re referring to sites with higher-than-average RTPs. Most online casinos favour games with lower RTPs because it frees up more money for the house. High-payout casinos, on the flip side, mostly list high-RTP games, leaving more to players in the long run.
Now, if by high-paying, you mean sites with the highest absolute payout amounts, consider popular jackpots. Today, pretty much every UK casino offers a progressive jackpot for some of their games. Some, like BetMGM, even link jackpots across several sites, increasing potential payouts.
Don't let one giant jackpot number hypnotise you, either. Balance high-RTP games with decent jackpots. You also don’t want to exclusively focus on chasing a high-paying casino. Other factors, such as bonuses and game coverage, should also factor into your online casino choice.
How to choose high-paying casinos
Decent jackpots and high RTPs are two common traits of high-paying casinos. Sounds simple, innit? It isn’t. These sites usually hide tricky terms. Here are some to note:
Confirm available jackpots
Most high-payout online casinos in the UK feature jackpots that easily climb into millions of pounds. In 2025, for example, Betfred’s Mega Moolah paid out £11 million for the grand tier. bet365’s Jackpot 365 runs every month, splitting over £9 million across all its jackpot tiers.
High-payout casino buffs know to check the available jackpots to test their upper limits. Of course, don’t count on actually hitting one. Even the most frequently paid-out jackpots, like Jackpot 365, pay out a few tiers once per month.
Check average game RTPs
A more relevant payout measure for the average online casino player is average game RTPs. RTP stands for return-to-player, and it’s simply the average return per pound you spend in the long run. Most sites display the RTP for every slot publicly. That way, you can easily tell which sites offer the highest-RTP games.
Most online casino games have RTPs around 93% to 94%. Anything above 94% is decent in the UK market, and you’ll find such titles on sites like bet365 and Star Sports. It’s good to hunt for jackpots, but game RTPs are more likely to impact your day-to-day experience.
Note: Don’t expect to always make £0.94 for every £1 spin just because a game has a 94% RTP. The RTP only shows the average amount the online casino makes available for payouts. Individual spins may not pay out the RTP, but it often normalises in the long run.
Check payout limits
Many sites promise good payouts, only to limit you to a few thousand pounds when you try to withdraw. You don’t want that. Before settling for a high-payout casino, always review the limits to see if it lets you cash out winnings and jackpots.
Most online casinos disclose their payout limits in their terms or Help Centre. If the site has live chat, you can text them to ask about payout limits. And yes, limits usually also change based on payment method, so check which ones would work for you.
Review bonus terms
Okay, this is where stuff gets plain annoying. Bonuses may seem unrelated to high payouts until you come across crafty sites. A common example is casinos that apply wagering requirements to both a deposit and its bonus. As a result, you can’t cash out winnings, even after exhausting your initial bonus. Some sites also cap bonus winnings to about 5x the bonus amount. That way, you can’t cash out as much as you’ve won from playing through your bonus.
So yes, read through the fine print when choosing a high-paying online casino so you know what to expect. Before hitting “claim” on a bonus, check the rollover, win limits, and what voids any winnings. That way, you know exactly what to expect from the site’s games and bonuses.

If you think bet365’s Jackpot 365 is impressive, you’ve not seen MGM Millions. Like Jackpot 365, MGM Millions is a progressive jackpot for select games like Legacy of Dead and Pirots 5. When you opt in, you pay £0.09 extra per spin, compared to Jackpot 365’s £0.10. The irony here is that the highest jackpot tier has exceeded £40 million, way higher than Jackpot 365’s over £9 million monthly.
Besides BetMGM’s jackpot, the site has a good library of high-RTP games. Pragmatic Play’s Big Bass Splash, for example, comes with a 96.71% RTP. The site has a category for popular games, so you can see all the high-payout games others are playing. If you want a go at one of the biggest online casino jackpots in the UK, try BetMGM’s.

If by good payout, you mean high RTP, Betfred might be more appealing. The site features instant games with over 99% RTP, such as Break the Bounty LuckyTap and Test Your Strength LuckyTap. It doesn’t skimp on slots either; it offers several with over 97% RTP.
If you’re here for jackpots, Betfred works, as it usually has several running at once. Its biggest, Mega Moolah, paid out over £11 million in 2025, one of the biggest jackpots in the UK. Betfred is not paying out any £40 million jackpot anytime soon, unlike BetMGM. So, if you can make do with high-RTP slots and decent progressive jackpots, it’s worth checking out.

Star Sports doesn’t offer progressive jackpots like Betfred or BetMGM. Its strength lies in its hundreds of slots, many with over 96% RTP, qualifying it for this list. For starters, it covers hundreds of Pragmatic Play’s high-RTP games. This list includes popular names like Sweet Rush Bonanza and Gates of Olympus 1000, among other slots.
What’s more, Star Sports is currently running a year-long Drops & Wins promotion with a $25 million prize pool. The prize is spread across 100,000 prizes every week, so it’s far away from a jackpot. With its numerous high-RTP games and the occasional bonuses, it’s one of the best-paying casinos in the UK.

Conclusion – Play high-RTP games on the best-paying UK casinos
When hunting for high-paying casinos, game RTPs are the first thing to check. Sites like BetMGM and Betfred excel here, offering games with as high as 99% RTP.
There’s a catch, though. High payouts aren’t just about RTPs; jackpots show the maximums you can expect from online casinos. All the more reason to check out bet365 and BetMGM. The former has Jackpot 365 with an over £9 million monthly prize pool. BetMGM, on the other hand, is behind the famous MGM Millions Jackpot, which can exceed £40 million.
