We’ve been in the industry for over 25 years and have seen the best of the best online casinos form, grow and offer players a great gaming experience. Here’s our round-up of the top 20 we recommend for this year, or head to our full list of the top 100 online casinos in the UK.

Our Top Picks for Online Casinos in the UK

Let’s take a closer look at some of our top picks. Below we’ve rounded up the best online casinos in the UK by category – so you can find the one that works best for you.

Best Casino Apps

oddschecker’s Pick: bet365 Casino

For the best casino app, bet365 is our top choice. With high ratings from both Apple and Android users, the app delivers an excellent user experience across the board. Whether you’re playing slots, table games, or live dealer titles, the app is smooth, fast, and user-friendly.

• Editor’s insight: “bet365 is truly a mobile-first brand. In fact, they rolled out 19 iOS app updates in 2024 alone. The latest version (23.20.0) has strong reviews, with users praising its faster game load times and cleaner, more intuitive interface.”
• User review:"The bet365 Casino app is easily the best I’ve used. Games load quickly, it’s super easy to navigate" - Sarah T, oddschecker member since 2025

Best Casinos for Bonuses

oddschecker’s Pick: Paddy Power

Not all welcome bonuses are made equally, and Paddy Power proves that. Right now, you can grab 50 free spins plus an extra 10 bonus spins on Paddy’s Mansion Heist. Plus, if you deposit £10 you’ll unlock 100 more - all with no wagering requirements.

• Editor's insight: "What really sets this offer apart? No wagering requirements. In the UK, most casino bonuses have come with 30x-50x playthrough requirements. But with Paddy Power, what you win is yours to keep. The one catch? You’ll need to make your first deposit using a debit card or Apple Pay, as other payment methods aren’t eligible."
• User review: "I’ve tried other sites where you win something, but you can’t cash out without jumping through hoops. Depositing with my debit card was easy, and I’ve stuck with them because the games are solid and the promotions keep coming." - David L, oddschecker member since 2024

Best Paying Online Casinos

oddschecker’s Pick: bet365 Casino

Some of the best online casinos openly share their payout percentages - a helpful indicator of how much players, on average, can expect to win back over time. While payout rates can vary across games, a higher overall percentage usually signals a fairer and more player-friendly casino. After thorough testing, bet365 Casino takes our top spot for payout rates. With an impressive average payout of 98%, bet365 consistently ranks well above the industry standard.

• Editor's insight: "Sure, a 98% payout rate is outstanding - but bet365 also delivers remarkable consistency, fast withdrawals, and an experience you can rely on. Players aren’t just looking for high returns, they want fair games, secure payments, and transparent terms. bet365 checks all those boxes."
• User review: "I’ve played at a lot of casinos over the years, but bet365 is where I always come back. Payouts feel fair. There’s no messing around with confusing terms or endless waiting." - Lauren M, oddschecker member since 2024

Award Winning Casino Sites in the UK

Industry awards can help separate the good casinos from the exceptional. In the UK, the two most respected awards are the EGR Operator Awards (often called the ‘Oscars’ of iGaming), and the Global Gaming Awards (an internationally recognised event for online and land-based operators).

These awards aren’t just for show, they’re judged by industry experts and reflect player experience, innovation and trustworthiness. Winning one means the casino has gone above and beyond in several areas. Here are some of the standout winners from the past few years:

Even More Award-Winning Casinos

How We Rate the Best UK Online Casinos

Before UK casino sites make it to our shortlist, they undergo a comprehensive review process. We have a team of 12 casino analysts who score every casino out of five based on strict criteria and real data. On average they spend 20-25 hours reviewing each casino and explore 10 key categories: safety, games, software, welcome offers, bonuses for existing players, deposits, withdrawals, mobile experience, site usability, and real user feedback. Here’s a snapshot of what we focus on to ensure you’re getting a safe, fair and top-quality experience:

• Safety and security: We only recommend casinos that are fully licensed by the UK Gambling Commission. This ensures the site is operating legally, protects your funds and that it’s is regularly audited for fairness.
• Games and software: We look for casinos with a big game selection – ideally 1,000+ games including slots, table games and live dealer options. But we also dig deeper, checking the quality of the game titles and that games are offered by at least 8 different software developers.
• Bonuses: We look for fair, generous welcome offers. We favour bonuses with wagering requirements under the industry average (30x). Plus, we look for transparent terms like long expiry windows (ideally 7-14 days) and no maximum win caps.
• Mobile play: More than 70% of UK players now game on mobile. So naturally, we favour casinos that have a smooth, regularly updated app (at least six updates per year). We also track app store reviews to see how they’ve held up over the last 12 months.
• Real user feedback: We listen to what players are really saying. We read the latest user reviews from real players to uncover issues like delayed payouts, poor customer support or app glitches. If a casino’s letting players down, we’ll factor that into the equation.
• Customer support: We prioritise casinos that offer 24/7 live chat or email support. And even better if the support team are based in the UK or Europe and have experience handling local expectations and regulations.

How Do We Collect User Feedback?

Our registered members are asked to rate each casino out of five via the oddschecker app. Our users score in exactly the same was as our casino analyst team. We pool these ratings with our own expert analysis to give each casino site a fair and transparent score. These ratings are then checked and updated every three months.

Why Online Casinos Might Have a Poor Rating

If an online casino has a low rating, there's a reason why. It might be that the games and bonuses aren't up to scratch, but it's more likely the casino isn't safe to play at. If the licensing isn't clear or if there are lots of negative user reviews around fraud or cashout issues, we listen. We'll never recommend an unsafe or untrustworthy online casino.

Editor's insight: If you're dealing with a dispute with an online casino, you can contact IBAS, a service approved by The Gambling Commission to help resolve disputes.

Only Trusted, UKGC-Licensed Casinos

We don’t list just any casino on our shortlist. Every site we feature is fully licensed by the UK Gambling Commission (UKGC), meaning it meets their strict standards for player safety, fairness and security.

How Does the UKGC Protect Players?

The UKGC was set up under the Gambling Act 2005 to make sure online casinos operate responsibly and legally, Here’s how they help keep players safe and what you can expect from casinos on our shortlist:

1. Licensing: Every UKGC-licensed operator goes through a rigorous approval process that can take up to 16 weeks. This includes background checks and financial audits to ensure they’re fit to operate. In 2023 alone, 30+ operators were rejected for non-compliance.
2. Fair games: The UKGC lets independent agencies like eCOGRA or iTech Labs verify that games are random and fair. The UKGC then monitors operator results and payouts to ensure they’re legitimate.
3. Banking protection: Licensed UK casino sites can only offer approved payment methods by the Financial Conduct Authority (FCA). That means your funds are only ever processed through regulated financial networks.
4. Data protection: UK casinos must comply with the Data Protection Act and use strong SSL encryption to protect a player’s data. They must also follow strict Know Your Customer (KYC) checks to prevent fraud and block underage gambling.
5. Safer gambling: Since 2019, self-exclusion through the GAMSTOP scheme has been mandatory. Casinos must also promote safer gambling by offering tools like deposit limits, time-outs and self-exclusion.
6. Penalties: The UKGC can act when rules are broken – this can include issuing warnings, removing licences, or imposing financial penalties. Millions in fines are made each year to operators that breach the rules.

Bonuses at Top Online Casinos

The best online casinos offer a wide range of bonuses designed to attract new players and reward loyal customers. Understanding how each bonus works (and which ones offer real value) can help you maximise your bankroll.

Welcome Bonuses

Welcome bonuses are the headline offers most casinos use to attract new players. Typically, these bonuses reward you with extra funds, free spins, or a combination of both when you make your first deposit. A quality welcome bonus should offer a balance between a generous reward and fair wagering requirements, so you can actually convert your winnings into real cash.

Deposit Match Bonuses

Deposit match bonuses reward players by matching a percentage of their deposit, often ranging from 50% to 200% or more. These bonuses are not limited to first-time players, with many casinos offering regular reload bonuses to keep existing customers engaged. The main things to watch out for are the maximum bonus amount and the wagering requirements, which determine how much you need to bet before you can withdraw your winnings.

No Deposit Bonuses

No deposit bonuses are highly sought after because they allow you to play and win real money without making a deposit. These offers usually come in the form of a small amount of bonus cash or a limited number of free spins. However, no deposit bonuses often come with strict wagering requirements, maximum win limits, and tight timeframes, which can make cashing out winnings more challenging.

Free Spins Bonuses

Free spins bonuses give you the chance to play selected slot games without spending real money. These bonuses may be offered as part of a welcome package, as a standalone promotion, or through loyalty rewards. It’s important to check which games the free spins can be used on, as many casinos limit them to specific slots, often with varying return-to-player (RTP) rates. Wagering requirements can also apply to winnings from free spins, although some casinos offer no-wagering free spins for added value.

No Wagering Bonuses

No wagering bonuses are among the most player-friendly offers in the online casino industry. With these bonuses, any winnings are paid in real cash with no further playthrough required, so what you win is yours to keep!

Cashback

Cashback bonuses return a percentage of your losses over a specific period, usually daily, weekly, or monthly. These bonuses can vary significantly, with some offering as little as 5% while premium casinos may return up to 20% of your losses. For savvy players, cashback offers are a great way to claw back funds when playing high-volatility games.

VIP Rewards and Special Promotions

VIP programs and special promotions are designed to reward loyal players with exclusive benefits. These generally vary, but commonly include higher cashback rates, faster withdrawals, personal account managers, and bespoke bonus offers.

Best UK Online Casino Payment Methods

We know one of the biggest concerns for users is the range of payment methods on offer. Licensed casinos will only offer FCA-approved payment options. Some of the most popular, secure casino payment methods in the UK include:

• Debit cards: Still the most widely used option in the UK, debit cards like Visa and Mastercard are accepted at nearly all UK casinos.
• Mobile wallets: Mobile wallets like Apple Pay and Google Pay let you deposit quickly and securely on your smartphone.
• E-wallets: PayPal, Skrill and Neteller are some of the biggest e-wallets in the UK. They’re popular for their lightning-fast withdrawals – sometimes instantly.
• Prepaid cards: Paysafecard is the most well-known prepaid option that lets you top up your casino account using a voucher code. Prepaid cards are ideal if you want more control over your spending.
• Pay-by-phone: With providers like Boku and Payforit, you can make deposits that are charged directly to your mobile phone bill. It’s fast and convenient, though it doesn’t typically support withdrawals.

Top Tips for Playing at Online Casinos

Whether you’re new to the UK gambling world or just want to sharpen your strategy, these are our top tips to help you play smarter, safer and with more confidence.

1. Don’t Treat Your Bonus Like Free Money

Bonuses may seem like free gifts, but they come with T&Cs and fine print to read. Try to look beyond the headline and check things like wagering requirements, withdrawal limits and any game restrictions on offer. Think of your bonus as a tool to explore the casino (and not a shortcut to easy winnings).

2. Play For Free First

Most casinos will offer practice or demo modes so you can test out games before playing for real money. These are really worth it – demos can let you try new games, learn the rules and test out new strategies without risking a penny.

3. Check the Casino’s Payout Percentages

Before you play, check a game’s Return to Player (RTP) rates. Some sites are more transparent than others, but the best ones will clearly display the average payout percentages across games. A higher RTP doesn’t guarantee a win, but over time it could make a difference to your results.
