Note: I can't offer you the exact RTP (Return to Player) for each because these casinos haven't published such info. But just so you know, all these UK casino sites have an average return rate higher than 96%, based on games' RTPs and real player experience.

Now, let's take a closer look to help you pick more easily.

#1 Pub Casino - Best High Payout Casino Overall

Some basic facts about the casino? Features over 1,400 most-played slots in the UK. Cashouts are usually completed in less than 24 hours. Nice, right? Plus, it only partners with big-brand game providers.

What I Liked

  • The game library is decently big.
  • Various UK-friendly payment options.
  • Multiple Slingo titles (for fans).
  • The site's mobile-optimised.

I Didn't Like

  • Only supports GBP.
  • Limited promos.

#2 All British Casino - All-Time 10% Cashback

Over a decade in the industry makes it a reliable pick among UK players. Plus side is that it also offers over 700 mobile games (for those who like to play on the go). And overall, everything here seems to be designed for UK users.

Don't forget that you'll cash out with the same method you used to deposit. Plus, withdrawals won't take much to be approved, but make sure to verify your account in advance to avoid delays.

Pros

  • User-friendly website.
  • Renowned game developers.
  • Permanent 10% cashback for all users.
  • Most popular jackpot slots.

Cons

  • Your withdrawals won't be processed during weekends.
  • No casino app for Android users.

#3 Casushi Casino - Best Payout Slots

Interesting name, right? I've known this one for a while now.

Casushi stands out from the rest through a unique loyalty programme, customer support that's actually 'supporting' (user-approved), and high-payout slots and table games.

Casushi processes payouts pretty fast. It depends on what payment option you use. I'd use Skrill, Neteller, or Trustly - they promise to deliver your cash in up to 2 business days.

Liked

  • Well-selected slot titles (fans of progressives and megaways will approve).
  • Regular promos, including the loyalty club.
  • Optimised for all mobile devices.

Not a Fan Of

  • No poker games.
  • Small welcome offer compared to other UK casinos.

#4 Betfred Casino - Established All-Rounder

Betfred supports debit-card, bank-transfer and selected e-wallet withdrawals, giving UK players several ways to cash out.

Processing time still depends on the payment method and account checks, so compare the live cashier terms rather than treating any payout time as guaranteed.

#5 PlayOJO Casino - Wager-Free Bonuses

Almost 10 years on the market, but the name speaks for itself. You'll find PlayOJO in most top lists, for many reasons and this time it's for being one of the best high-payout online casinos in the UK.

I remember them once publishing an exact number for their overall RTP, claiming it to be higher than at others - can't find it now on-site, though.

OJO usually processes withdrawals instantly, so you won't have to wait long for your payout. But do check for extra fees.

Perks

  • Exclusive bonuses and promos.
  • No wagering on free spins (my fave part).
  • Regular tourneys to keep you busy.

Upsides

  • No deposit match bonus for new users.
  • A few more table games in the game lobby wouldn't hurt.

#6 Fun Casino - Biggest List of UK Payment Methods

For a strat, you'll find more than 1,000 slot titles. Plus, Fun Casino accepts all the most popular payment options in the UK. E-wallets, debit cards, and even prepaid cards. There's obviously something for everyone.

Luckily, transactions are also processed instantly by the casino. Warning: PayPal and Bank Transfer could take up to 3 working days.

Wins

  • Wide selection of slot themes.
  • 24/7 support through live chat, email, and even phone.
  • Huge choice of payment methods.

Flaws

  • No downloadable app.
  • High wagering on bonuses - up to 50x.
  • No roulette games (if you're here for them).

How to Pick the Best High-Payout Casino?

Here's how I separated the real ones from the "thank you, next."

I Start With Licensing

A UKGC stamp in the casino's footer is a must if you actually wanna see that winning hit your wallet.

I don't stop here. I either click on the licensing number to verify it or check it with the UKGC's official website.

Then I Check The T&Cs

What I look for is any wagering traps, unreasonable withdrawal limits (and fees), sneaky bonus terms, and any weird cashout rules.

Licensed casinos don't usually allow all this, but you know the saying: "Better safe than sorry."

I Look into the Game Lobby

Nothing but low-volatility stuff? Pass by. I look for game variety, decent RTPs, and quality providers.

Did you know that the UKGC requires all licensed operators to monitor the RTP performance of their games constantly? So that it meets the provider's theoretical return rate. If you're playing at a regulated casino, you won't get played.

Next, I Test the Cashier

If you can't cash out properly, what's the point of a high-paying casino, right?

So, I check for cashout speed, supported options, casino processing time, and whether you can get your cash without a fight at all.

Not Least, I Check for Safer Gambling Tools

The last green flag.

If a casino isn't bothered with limits, time-out options, or reality checks, it won't make it to my list of the best payout sites. Period.

Which Casino Games Pay Out the Most?

A high RTP and a quick withdrawal are different things. RTP describes the game maths; the casino still has to process your cashout.

The Gambling Commission explains RTP as an average over many plays, not a return you can expect from one session. The examples below use provider-published figures. Check the rules in the version you open, because the configuration and game mode can matter.

Slot RTP examples compared

SlotProviderPublished RTP
Book of 99Relax Gaming99%
Mega JokerNetEnt99% published figure; check the mode and game rules
1429 Uncharted SeasThunderkick98.6%
Marching LegionsRelax Gaming98.12% published at release
Blood SuckersNetEnt98%
JokerizerYggdrasil88.8% to 98%
Big Bad WolfQuickspin90% and 97% models listed by the provider
Provider figures are linked by game; the rules of the version you play take priority.

What to compare in table-game rules

GameWhat to read before comparing returns
BlackjackCheck the exact variant, blackjack payout and drawing, doubling and splitting rules. Keep optional side bets separate from the main game.
French rouletteLook for La Partage. In Evolution's version it returns half an even-money stake when zero lands; that rule does not apply to every bet.
Casino Hold'emRead the main-game and optional side-bet paytables separately. A single percentage without its betting assumptions is not a useful comparison.
Compare the exact game rules, not just the studio name or launch year.

For example, Evolution explains the La Partage rule for its French roulette tables. That is the sort of detail worth checking before applying one RTP figure to a whole game category.

What are the Fastest Payout Methods?

If you want to get hold of your winnings as fast, you could use the following UK-friendly payment options:

E-Wallets (PayPal, Skrill, Neteller): Will process your payment in less than 24 hours. But not all UK casinos support them, and you might be charged extra fees when transferring cash to your bank.

Instant Bank Transfer (Trustly): Smooth and speedy transfer to your bank account within 24 hours.

The rest either support deposits only or take more than 2 business days to deliver your cash. Either way, make sure to verify your account after sign-up if you want to avoid delays at cashout.

Final Thoughts - Can You Increase Your Payout?

Wanna boost your payout even more, huh? Well, start with checking every game's RTP (find it in the game's info box) and pick the highest. Don't forget to go through the fine print before claiming a bonus. Also, check the withdrawal terms for your payout method (only use verified options).

Are high-paying online casinos worth it at all?

If you play regularly (plus, you're more of a high roller), then yes. Doesn't mean you can bet recklessly and chase losses all you want, though. You'd better keep tabs on your wins and losses, as well as stick to games you understand. Don't expect bigger payouts by chasing losses.

Picking a licensed casino with upfront terms and transparent RTPs is what you should start with if you want to play it smart.

Seems like that's it for today. Same place, same time?
