Best Casino Sites in the UK – Our Top 5
Readers can learn about the welcome bonuses offered by the leading casino websites in the UK via the table above.
But there’s more to a good casino site than just a bonus; there’s other factors to consider. So we’ve narrowed the search to our top five brands based upon their quality of games, usability of their site, promotions for new and existing players, variety of accepted payment methods and other key features.
Bet365 – Our Review
Bet365 was founded in the year 2000 as a high street betting brand, subsequently diversifying into online sports betting and casino games.
Licensed by the UK Gambling Commission, new players to bet365 can claim free spins on ten of their first 20 days as a customer – it could be five, ten or 20 free spins on each day.
The bet365 casino has a sizable collection of 2,000+ games across all of the key categories, with promotions for existing players that include entries into cash giveaways.
However, the bet365 casino doesn’t carry games from all the leading software suppliers, so therefore they are missing some classic slots that are available elsewhere.
| ✅ bet365 Pros | ❌ bet365 Cons |
|---|---|
| Ten days of free spins welcome bonus | Missing software firms and classic slots |
| Huge games library | |
| Promotions for new and existing players |
NetBet – Our Review
NetBet was launched as a specialist online betting operator in 2001, offering sports betting and online casino platforms that customers can access from a single account and bankroll.
Licensed by the UK Gambling Commission and other authorities around the world, NetBet offers their new customers the chance to claim 100 free spins when they deposit and bet £10. There’s zero wagering requirements, but a maximum win limit of £100.
The casino has games from all of the leading software suppliers, with new releases joined by all-time classics such as Starburst and Big Bass Splash.
NetBet could improve by removing the 1.5% fee that they charge for withdrawals of £500 or more. They also offer no telephone customer support, while their live chat help team is only available for select hours during the day.
| ✅ NetBet Pros | ❌ NetBet Cons |
|---|---|
| 100 free spins for new customers | Limited customer support |
| Games sourced from the best developers | |
| Lots of promotions and a loyalty club |
Coral – Our Review
The Coral betting brand was first established in 1926, adopting new technologies along the way – such as their online casino, which was launched in 2011.
One of the first gambling brands to be handed a UK licence, Coral is a trusted operator that offers new customers the chance to claim bonus funds (£30) – not just free spins – in their welcome package; that explains why they are considered to be one of the best internet casinos.
Amongst a library of games that has nearly 5,000 different options, Coral has slots and other titles that are completely exclusive to them, as well as a free-to-play games that can pay out free spins and cash prizes.
But our research indicates that they could improve in some areas. The wagering requirements attached to their welcome bonus are 40x, while an increase in the number of payment methods accepted would be helpful.
| ✅ Coral Pros | ❌ Coral Cons |
|---|---|
| £30 in bonus funds for new customers | 40x wagering on welcome bonus |
| 4,500+ game library | |
| Promotions and free-to-play games |
Paddy Power – Our Review
Although headquartered in Ireland, Paddy Power is still regarded as one of the finest British online casinos available today.
Established in 1988 and licensed by the UK Gambling Commission for much of that time, Paddy Power holds the distinction of offering new players one of the best free spins offers around.
The no deposit bonus of 60 free spins, with a further 100 free spins available later, allows new customers the chance to explore Paddy Power’s huge games library – nearly 2,000 titles can be enjoyed.
Their casino could be improved with faster withdrawal speeds, with some debit card transactions taking up to four business days to complete.
| ✅ Paddy Power Pros | ❌ Paddy Power Cons |
|---|---|
| One of the best welcome bonuses around | Slower-than-average withdrawal speeds |
| Nearly 2,000 different games | |
| Varied selection of ongoing promotions |
BetVictor – Our Review
BetVictor was established as a gambling operator back in 1946, before launching their first online casino in the year 2000.
Fully approved and licensed by the UK Gambling Commission, BetVictor now offer a handy welcome bonus – bet £10, get a £30 bonus plus 30 free spins – as well as a library that features a small but high-quality selection of games.
The Spinners Club loyalty programme rewards players with up to 200 free spins each week, although a downside to the welcome bonus is that the wagering requirements are 40x.
The BetVictor casino site also isn’t the most pleasing on the eye… although beauty is in the eye of the beholder.
| ✅ BetVictor Pros | ❌ BetVictor Cons |
|---|---|
| Decent welcome package | 40x wagering on welcome bonus |
| Spinners Club loyalty scheme | |
| Excellent casino app |
Best UK New Casino Site
Although not new as such, Unibet is still one of the more recent British online casinos to open its doors to UK players.
They welcome new customers with a ‘deposit £10, get a £40 bonus’ offer, which in percentage terms is one of the best offers available at casino websites in the UK.
The games library features titles from NetEnt, Microgaming, Play n’ Go and more, while 24/7 customer support is available via phone, email and live chat.
Licensed to operate in the UK, Unibet is one of the most appealing new casino sites to hit the market.

Best Casino Sites Per Feature
Players that cherish particular features from their chosen site can learn about the best internet casino for each of the main factors here.
Best Casino Sites for Games
Our research has revealed that the best rated online casino purely for their games is Coral.
The reason is that they combine both quantity and quality. There’s a library of 5,000+ slots and table games to choose from, as well as live casino, bingo, poker and more.
Players can try their hand at jackpot slots, games with unique features like Megaways, or play classic fruit machines and video slots that have been sourced from Playtech, Blueprint, Pragmatic Play, Inspired Gaming and so on.
Best Casino Sites for Jackpots
The best rated online casino for jackpot games is Unibet, who not only have a huge selection of jackpots to choose from, but they have also designed their site in a way that makes choosing particular jackpot slots that much easier.
There’s nearly 250 different progressive jackpot slots at Unibet, but players can also sift through the collection by jackpot type: Mega Moolah, Jackpot King, WowPot! and King Millions being just some of the options available.
Best Casino Sites for Sign Up Offers
The undisputed king of British online casinos when it comes to sign up offers is Paddy Power.
That’s because their welcome bonus has two elements: the first is a no deposit bonus of 60 free spins, with a further 100 free spins available when new customers deposit and bet £10.
It’s rare for a mainstream operator to offer a no deposit bonus these days; let alone a traditional ‘bet and get’ offer as well.
New customers only. T&Cs apply
Best Casino Sites for Existing Customer Offers
The best internet casino for existing customer offers, as per our research, is Betfred.
They offer a number of different ways for their players to earn free spins. There’s a daily Mystery Free Spins reward for everyone, as well as unique promotions such as Free Spins Acca and Football Cash Collect, where customers can claim a ‘bet £10, get 10 free spins’ offer.
Betfred also runs a Comp Points programme, with players accruing points form their staking that can be exchanged for free spins, cash prizes and more.
Best Casino Mobile Sites
Our investigations reveal Ladbrokes as the best mobile casino site.
Their mobile site and app have both been designed with small screen sizes in mind, but still offer a huge range of games, a live casino and the chance to claim promotions via a smartphone or tablet.
Ladbrokes also fits the bill as a pay by mobile casino, with Apple Pay and Google Pay just two of the payment methods that the brand accepts; alongside more traditional options such as Visa, Mastercard and PayPal.
Best British Online Casinos for Blackjack
Blackjack enthusiasts should consider the welcome bonus available to them at casino websites in the UK.
Many casinos offer free spins for slots, but some – like Coral – offer bonus funds that can be used on blackjack and other table games.
Players that load up the table games selection at Coral are met with a comprehensive choice of titles. There’s traditional blackjack, live versions of the game and exclusive blackjack variants that customers won’t find anywhere else but Coral – Blackjack Fortune Spinner and Platinum Blackjack Pro to name just two.
Best Casino Sites for Roulette
Despite being one of the new casino sites when compared to more established names in UK betting, Unibet stood out as a supreme casino for roulette players in our research.
There’s the £40 welcome bonus that can be used on roulette games, for starters, as well as Unibet branded exclusive games: Lightning Roulette and Vegas Drops Roulette to name just two.
Unibet is also a solid choice for those that enjoy live roulette, with our investigations counting more than 50 different options in live roulette gaming.
Best Live Casino Site
One of the ways that bet365 identifies itself as one of the best British online casinos is via its live gaming environment.
There’s more than a dozen bet365 exclusives across live blackjack, roulette and baccarat, as well as their ‘top 10’ of table games, game shows, dice, poker and lotto ball.
Live giveaway games are exactly as the name suggests, with all of the above housed in a casino site that is easy to use and navigate, with intuitive headings and menus.
How to Choose Your Casino Site
After tirelessly registering with, and playing at, scores of operators in our testing, we were able to come up our rundown of the best internet casino sites available in the UK right now.
Readers must now decide which is the right online casino for them…
There are numerous different variables to consider, so it’s important for players to decide whether they want a casino that specialises in a particular area – i.e. the best promotions for existing players, or the best roulette casino etc, or if they want a solid ‘all-rounder’ that ticks all of the boxes.
The Welcome Bonus
The first interaction that new customers have with a casino is the welcome bonus. We have registered with all of the operators detailed in this article, so can confirm that the sign-up process was simple and hassle-free for each.
Players that prefer slots may opt for a casino site that offers a free spins bonus. Those that favour table games may opt for a welcome offer that has bonus funds, rather than free spins, at its core. Remember the importance of wagering requirements too… how difficult will it be to turn bonus winnings into withdrawable cash?
The Games
Something that the leading British online casinos have in common is a first-class games library.
In our experience, players want a mix of quality and quantity. They want to be able to choose from a wide selection of slots and table games, but they want those titles to be genre classics or sourced from the most reputable software developers.
Although live casino gaming and other areas, such as poker and bingo, are more unique to the individual player, the availability of these may also be a key consideration.
The Ongoing Promotions
After a while, new customers will have played through their welcome bonus and be left with a different question to ponder: what other promotions can I claim?
In our research, the best rated online casino sites all shared a common attribute: they offer a number of promotions for both new and existing customers alike. That way, they’re able to create loyalty amongst their player base… while players themselves get to take advantage of offers that will sustain them for weeks and months to come.
The User Experience
Even if a UK online slots site ticks the boxes listed here, it won’t count for much if their website or app is poorly designed or difficult to navigate around.
That’s just one element of the user experience, alongside payments (variety of methods accepted, payout times etc), security and customer support (what options are available? For how many hours per day?).
The Betting Experience
One other thing for players to consider is how they plan to bet.
Those that will only be playing casino games can use the criteria above to select their perfect casino site. But those that plan to bet on sports as well as play slots and table games will need to consider the overall sports/casino experience.
Fortunately, the operators listed on this page are renowned as being amongst the best betting sites, but this is another variable to consider when choosing a casino to join.
