Best UK Online Sports Betting Sites

If you’re looking for the best online sports betting sites in the UK, then you’ve come to the right place.

Let’s face it - the UK is sports-mad. And there’s nothing better than placing a bet on your chosen sportsperson, horse, or team.

Whether it’s football, rugby, cricket, tennis, boxing, golf, snooker - having some money riding on the result always makes watching sport more interesting.

With around £14 billion spent on sports betting each year, it’s one of the nation’s favourite ways to gamble.

We make sure that all of the online sports betting sites that we recommend or mention on our site are fully compliant with UK gambling laws and are licensed by the UKGC to provide betting services in the UK.

To make sure that you are guaranteed a fair, safe, and secure betting experience, make sure you look for the Gambling Commission logo or a statement declaring compliance with UKGC licensing regulations on the betting website.

That’s why we’ve put together this complete guide to the best online sports betting sites in the UK.

What Are Online Sports Betting Sites?

Before we go through the rundown of the top 20 sports betting sites in the UK, let’s first pause for a moment and discuss exactly what we mean by online sports betting sites.

In a nutshell, an online sports betting site is a website or betting app that allows you to place real-money bets on the outcome of a sporting event or elements of that event.

For instance, you may place a bet on a certain horse winning a race, a specific footballer scoring the first goal in a match or the number of fouls in a rugby match.

The online bookmaker studies the probability of the event happening then applies a betting margin (usually between 4 to 8%), then offers odds for punters to place bets on the outcome in question.

Our top 20 online sports bettings sites are chosen carefully using strict criteria to compare the quality of the site (more on how we compare the sites later on in this guide). But first, let’s take a look at which UK betting sites made the top 20.

#1 Best UK Betting Site - bet365

For a company that advertises itself as the world’s favourite online sports betting company”, you would expect Bet365 to offer exceptional online sports betting service. The good news is that  Bet365 delivers in spades, which is why it has topped our list of top 20 online sports betting sites.

Bet365 has become a household name in the UK with big sports sponsorship deals and regular television and internet advertising. It is a brand that can be trusted and is fully UKGC licensed.

They are one of the titans of sports betting these days, with a sportsbook that boasts dozens of sports including some of the less popular ones such as badminton, handball, eSports, etc. They also offer hundreds of betting markets, so if you’re looking for highly specialised bets on a certain sport, Bet365 is the place to go.

As you would expect from a site that has been going for so long, they have a great interface that is easy to use and navigate. Their customer service is second to none, with plenty of different deposit and withdrawal methods. The welcome bonus is excellent with up to £100 in free bets available as a matched deposit.

The only real downside of Bet365 is the lack of a loyalty reward program, but other than that it’s one of the best and safest places to bet on sports online in the UK.

Pros:

  • Lots of live streaming of sporting events
  • Fantastic user-friendly platform and mobile app
  • High-quality 24/7 customer service

Cons:

  • The sheer number of betting options on each sport may be overwhelming for beginners.

#2 Best UK Betting Site - Unibet

Unibet has been around since the early days of the internet and launched in 1997. Unibet offers a fully UKGC licensed online sports betting site, as well as online casino and poker games.

As you would expect from a company that has been around for so long, they know how to offer a good, reliable service to their customers and have built a sports betting platform that is unrivalled in terms of quality and fairness.

The big selling point of Unibet is the mobile app. It’s nothing short of brilliant, both in design and functionality. It’s super-easy to find the sport you want and to place your bet, and the whole experience just feels smooth and classy.

The promotions and bonuses at Unibet are also really good, with a £40 money-back welcome offer if your first bet loses, plus regular free bet special offers, usually connected to big sporting events.

The only slight criticism of Unibet is the lack of loyalty rewards and the fact that they only provide limited live statistics for in-play betting. Other than those minor problems, Unibet is still one of the best places to do your sports betting online in the UK.

Pros:

  • Some of the most competitive odds available online
  • Over 30% of sporting events have live streams
  • Exciting promotions and bonuses

Cons:

  • Live chat can be slow to respond with people reporting waiting times of up to 15 minutes.

#3 Best UK Betting Site - Betfair

Betfair is a bit unusual as it comes in two different forms - Betfair Sportsbook and Betfair Betting Exchange. For more information about the betting exchange, see the section above titled “Best Betting Exchange”. This mini-review will focus on the sportsbook side of Betfair.

The Betfair Sportsbook is a strong offering with every major sport covered, plus some of the more niche sports such as Gaelic sports and a wide range of winter sports. The betting markets and odds are competitive with other major sports betting sites.

The only real negative about Betfair is that the loyalty reward program only covers horse racing, so unless you’re a big horse racing punter, don’t expect to get too many promotions and free bets coming your way on Betfair.

Pros:

  • Excellent software and app with user-friendly and attractive interfaces
  • Good range of sports, betting markets, and high wagering limits
  • Very generous welcome offer - up to £100 in free bets

Cons:

  • The betting exchange may be confusing for new users and beginners

#4 Best UK Betting Site - Paddy Power

As you can probably guess from the name, Paddy Power is an Irish bookmaker. Formed in 1988, they moved into online sports betting and casino services and have grown to be one of the biggest online sports betting sites in the UK and indeed the world.

Paddy Power has a reputation as being a safe, secure, and fun place to bet on sports, and that reputation is well deserved.

As you would expect from a site with such a long history, Paddy Power offers a ton of sports and betting markets to choose from. You name any sport, and the chances are you’ll be able to find it at Paddy Power. 

They also offer some of the best promotions of any sports betting site in the UK with regular free bet refunds, money-back offers, boosted accumulators, and a lucrative loyalty reward scheme. 

Pros: 

  • Well-established bookmaker with a very good reputation for fairness and security
  • Wide range of sports and betting markets
  • Competitive odds across the board, with inflated odds in some popular markets known as “Power Prices

Cons:

  • Relatively low welcome bonus of just £10, but it is a zero-deposit, risk-free free bet.

#5 Best UK Betting Site - BetVictor

BetVictor is an iconic brand that started out in sports bookmaking way back in 1946, originally called Victor Chandler. BetVictor set up its online sports betting site in 1999 and they have been a major player in the sports betting scene ever since.

With a wide range of sports to bet on and huge betting markets, BetVictor provides plenty of entertainment for both amateur and serious gamblers alike.

Pros:

  • Generous welcome bonus - bet £5 to get £30 in free bets
  • Very good prices and competitive odds - relatively low betting margins
  • Unparalleled customer service

Cons:

  • Withdrawals take slightly longer than some other online betting sites.

#6 Best UK Betting Site - Betfred

Betfred is a well-known bookmaker brand in the UK with betting shops in most towns around the country. Betfred’s online sports betting site launched in the UK back in 2004 and has gone from strength to strength over the years. 

The main attraction at Betfred is the sheer number of sports and betting markets available to wager on. You can pretty much bet on any sport you can think of at Betfred, including eSports and Virtual Sports.

Horse racing is one of Betfred’s strong points, with more than 200 races covered daily on the site, most of which have a live stream so you can watch the race after you’ve placed your bets.

Betfred’s welcome bonus is good with £30 in free bets when you deposit £10. They also run regular promotions and bonuses for existing customers including plenty of winnings boosts such as an all-correct bonus and one-winner bonus for certain accumulators and speciality bets.

To sum up, Betfred is one of the safest and action-packed sports betting sites in the UK, so if you’re looking for somewhere secure to bet on your favourite sports look no further than good ol’ Fred!

Pros:

  • Great bonuses, promotions, competitions, and giveaways
  • Live in-play sports betting with live streaming for some events
  • Competitive odds and low betting margins

Cons:

  • User interface can be a bit clunky at times

#7 Best UK Betting Site - Betway

Betway has been around as an online sports betting site in the UK since 2006. Betway has a good sportsbook available, with plenty of sports including one of the widest range of eSports markets that you can find online.

The promotions are decent at Betway, although the welcome bonus could be better with just £10 in free bets on offer. Saying that they do offer some of the most consistent and competitive odds online, so if you are a frequent punter the lack of a good welcome bonus will soon be compensated by the potential for higher winners.

The main downside of Betway is that the in-play and live betting is limited and they only offer live streaming for a limited number of horse races.

Pros:

  • Excellent loyalty rewards program - Betway Plus
  • Competitive odds in most betting markets
  • Plenty of live streams to watch sporting events

Cons:

  • The withdrawal maximum limit is fairly low compared to other online bookmakers at 5 times the total deposited amount.

#8 Best UK Betting Site - SBK

SBK is a fairly new online sports betting provider, launched in 2019, that only provides mobile gambling. In other words, you can only sign up and play through their mobile app.

The advantage of this is they have fewer overheads with no website to run and maintain and can offer much better prices and odds than other online sportsbooks.

Pros:

  • “True price” odds that are decided by the market with very low betting margins
  • The social media-style community where punters can share tips and chat in the app
  • Good promotions offering free bets regularly

Cons:

  • Unable to play through a website, only on the app

#9 Best UK Betting Site - 888Sport

888 is one of the biggest and most trusted brands in online gambling, which means you are guaranteed good security and top-tier service. 888Sport caters to all types of sports bettors from beginner to advanced, with plenty of sporting events and markets to keep you entertained.

Pros:

  • Dozens of bonuses and promotions running all the time
  • High betting limits for high-rollers, yet small stakes allowed for casual gamblers
  • Excellent, well-designed software and mobile app

Cons:

  • Some withdrawal fees are well hidden - make sure you read the small print

#10 Best UK Betting Site - Netbet

Well known for its excellent coverage of horse racing, Netbet is an online sports betting site that delivers solid, good fun entertainment. Netbet is perfect for beginners as the platform is super-easy to use and you can place bets quickly, with no fuss.

Pros: 

  • Competitive odds and a wide range of betting markets
  • Very user-friendly interface and quick betting process
  • Strong customer service

Cons:

  • Bonuses and promotions could be a bit more generous.

#11 Best UK Betting Site - Quinnbet

Quinnbet launched an online sports betting site in 2017 and has grown exponentially, targeting the UK and Irish betting markets. They have wide coverage of sports, with betting markets available for pretty much every horse race and football match in the world, at any time.

Pros:

  • Wide range of sports - especially good for horse racing and football
  • No maximum withdrawal limit - good news if you win big!
  • Competitive odds and decent bonus offers

Cons:

  • A limited number of payment methods - no mobile payments and only a couple of e-wallets.

#12 Best UK Betting Site - MansionBet

MansionBet online sportsbook was launched in 2018 in the UK and has built a good, trustworthy reputation amongst British sports gamblers. The welcome bonus is easy to clear and fairly generous. They also offer lots of lucrative promotions and bonuses throughout the year.

Pros:

  • Plenty of ongoing offers and promotions
  • More than 30 sports available with dozens of betting markets
  • Good in-play betting feature with quick cashouts available

Cons:

  • No live streaming of sporting events, as yet.

#13 Best UK Betting Site - Parimatch

Parimatch is a new UK online sports betting site that launched in 2019 but has been around online since 2000 as a popular online sportsbook in the CIS states. It has already proven to be a hit with UK punters, mainly due to their generous bonuses and regular promotions.

Pros:

  • Very generous welcome bonus - bet £5 to £30 in free bets
  • Simple, easy-to-use interface and site layout
  • Competitive odds and plenty of betting markets

Cons:

  • They don’t have a mobile app available yet.

#14 Best UK Betting Site - William Hill

William Hill is one of the most recognisable and largest high street bookmaker brands in the UK, operating since 1934 - almost 100 years old! They have also built a very strong reputation for their online sports betting service.

William Hill is also well known for offering a top-notch online casino and very popular online poker platform.

Pros:

  • Excellent reputation for reliability, trustworthiness, and security
  • Wide range of sports, games, and betting markets
  • Very good bonuses and frequently updated promotions

Cons:

  • The welcome bonus could be a bit more generous

#15 Best UK Betting Site - BetUK

BetUK launched in 2018 and has quickly risen to be one of the top ten sports betting sites in the UK. For such a new site, they have a good range of sports available in their sportsbook, with more than 30 available, including some more obscure sports such as futsal, trotting, and a wide variety of eSports.

BetUK’s real strength lies in the number of betting markets on offer, especially for football where there are often more than 300 markets available for any given match. If you enjoy betting on the Premier League or any other football league or tournament, you’ll love BetUK.

The main downside of BetUK is that the bonuses and promotions leave a lot to be desired. The welcome bonus at the time of writing is just £5 in free bets. There is a matched deposit bonus of up to £100 available too, but the betting requirements are very difficult to clear - you only get 7 days to wager quite a lot of money. 

Other than the lacklustre bonuses, BetUK is a good sports betting site with plenty of choices, a good mobile app, and excellent customer service.

Pros:

  • Very wide range of sports and betting markets
  • Good welcome bonus offer
  • The user-friendly and intuitive website

Cons:

  • Customer service resolution times are a little on the slow side at times.

#16 Best UK Betting Site - 21.co.uk

21.co.uk is new to the UK sports betting scene. Owned by LeoVegas which is an online gambling giant, 21.co.uk is a safe and secure place to bet and is fully licensed by the UKGC.

21.co.uk scores highly for having a good range of sports, especially for a new site, and plenty of betting markets with competitive odds. They also offer a betting tips service for free, which is handy for regular punters.

The welcome bonus is fairly small, a £10 free bet for £10 deposit, but there are no wagering requirements to clear the bonus, which is a positive.

21.co.uk also offers a mobile app for apple and android, both of which are very well designed and user-friendly.

The only real negative is that 21.co.uk doesn’t provide any live streaming of sporting events, but maybe this is a feature they will add as the site grows in popularity.

Pros:

  • Highly competitive odds across a wide variety of betting markets
  • Excellent customer support through live chat or email
  • Quality interface and web design, both easy-to-use and attractive

Cons:

  • No welcome bonus for sports betting, but you do get free slot spins upon registration

#17 Best UK Betting Site - Kwiff

Kwiff is a unique and fun online gambling site and app that was first launched in 2015. Players will find an easy to use, fast, and exciting sports betting app with the chance of bets getting "supercharged" to massive odds.

Pros:

  • Supercharged odds randomly
  • Good range of sports and betting options
  • One of the best betting apps for speed and ease of use

Cons:

  • Sports betting promotions could be a little better

#18 Best UK Betting Site - MarathonBet

MarathonBet is a bookmaker that has been around since 1997, serving mainly the CIS region, until launching in the UK in 2017. Since then, they have established themselves as a decent sportsbook that offers some nice bonuses and a good selection of betting markets.

Pros:

  • Good promotions and bonuses and welcome offer
  • Safe and secure - fully UKGC licensed sports betting operator
  • Fast deposits and withdrawals

Cons:

  • In-play betting features are limited and could do with improvement

#19 Best UK Betting Site - VirginBet

VirginBet is owned by Virgin Enterprises Limited, which means it is backed by one of the strongest and most reliable brands in the world. The online sports betting site is well designed and user friendly, making it perfect for beginners and amateur sports gamblers.

Pros:

  • The excellent, easy-to-use interface on both the website and mobile app
  • Huge range of sports and betting markets
  • Wide coverage of live streams and live in-play betting

Cons:

  • Promotions could do with being a bit more generous, especially the welcome offer.

#20 Best UK Betting Site - Boylesports

Boylesports is a well known Irish bookmaker that offers online sports betting and is particularly renowned for its coverage of horse racing. Pretty much every race meeting worldwide is covered, which means there is a huge range of betting markets available.

Pros:

  • One of the best online bookmakers for horse racing fans
  • Plenty of payment methods, with low deposit and withdrawal minimums
  • Free bet promotions run throughout the year, especially when big race meets are on

Cons:

  • Excellent for horse racing, but slightly limited when it comes to other sports.

How We Review & Compare Online Betting Sites

We want to reassure you that all of our reviews and comparisons are independent and unbiased. We use strict criteria to make sure that we recommend only the best online sports betting sites in the UK.

The following sections explain what we look for in an online sports betting site and how we compare them to find the best ones.

Security, Safety, & Licensing

When it comes to sports betting online, we know that the security and safety of funds are really important. That’s why we only ever recommend betting sites and mobile apps that have been licensed by the UKGC. The UKGC ensures that sports betting providers run a fair system, with security measures in place to protect players’ funds.

We also compare feedback from players to make sure that the sites are actually sticking to UKGC regulations and not just paying lip service to them.

Banking & Payment Methods

If you’re placing sports bets online, you need a convenient way to deposit funds into your online account and withdraw any winnings if you get lucky. We analyse each betting site to see what payment and banking methods are available and also the average time it takes to get your cashouts. We then compare all the sites to help us rank them against each other.

All of the betting sites in our list accept a wide range of local and international payment methods ranging from debit/credit cards to e-wallets such as PayPal, Neteller and Skrill.

Promotional Free Bets & Bonuses

One of the best things about online gambling compared to high-street sports betting, is that you get lots more bonuses and promotions. We take an in-depth look at each site’s bonus system and regular promotions, with higher bonuses and frequent offers ranking higher.

All of the best betting sites offer high-value new customer sign up offers to attract new players. It is important to take full advantage of these signup offers, as you can only claim them once (on each bookie), and they almost always offer more value than any other promotion available.

Some punters even sign up to almost every legal bookie available to take advantage of these fantastic free bet offers. But, not all signup bonuses offer good value, and it is important to learn how to spot the best and avoid the worst.

Firstly, look at the wagering requirements on the bonus, to see how much you need to wager the amount to unlock the funds for withdrawal. The best bonuses come with no wagering requirements, but some, require you to wager the bonus 10x the amount, or even more on casino bonuses.

Secondly, check to see what restrictions there are on the bonus, whether you need to deposit using a certain payment method, or if the bonus can only be used on a certain sport, market, etc.

Lastly, it is important to check if you need to enter a bonus code, and what the minimum deposit and bet amount are to qualify for the offer. Not all bonuses have these conditions, but it is crucial to check so you do not miss out on claiming the offer.

Customer Support

Most betting sites offer live chat and email support, but not all of them are 24/7. Also, some resolution times are longer than others, so we take this into account when we are ranking the best betting sites in the UK.

We believe the best betting sites should offer 24/7 customer support with several methods of contact including a live chat, email, and free phone number.

This is certainly not the case across all betting sites, but the top five in our list all offer top-tier, 24/7 customer support with several contact methods.

Mobile Apps

The mobile app revolution means you can now place sports bets on your mobile device in a matter of seconds. We highlight whether an online sports betting provider has a mobile app or not and we also compare the useability and functionality of the apps.

We test the mobile betting apps, and mobile optimised betting websites to see which bookies offer the best mobile betting experience.

Compare which betting sites offer betting apps on Android and iOS below, and the results of our tests on our best betting apps in the UK page.

Range of Sports

The best online sports betting sites tend to have the largest range of sports and sporting events available, including obscure ones like water polo or arm-wrestling. We compare the sites to make sure you get the best entertainment value when you sign up for an online sportsbook.

Tied into the above is the depth of betting markets that are available. For the biggest sporting events, it is now not uncommon for there to be hundreds of different bets to pick from.

Quickly compare the top 20 sports betting sites in our list above, with the number of sports available, the average number of betting markets, and whether the bookie offers free live streaming and a cash-out feature.

bet365 is our number one pick for sports betting, with 30+ sports, free live streams, full and partial cashouts, high betting odds, and hundreds of betting markets.

High Betting Odds

The odds are all important when it comes to online sports betting. We look for the most favourable highest odds with the lowest betting margins, i.e. you get more back when your bet wins.

If you did not know, the betting margin is essentially how much a bookie "charges" you to place a bet. Simply put, the lower the betting margin, the higher the odds.

Below are the results of our latest independent betting margins tests. We analyse and test a range of betting odds across different markets, leagues and sports, to give an overall idea of the margins that betting sites charge.

As you can see below, the margins of the sports vary quite a lot from the best (SBK) to the worst (Paddy Power).

  1. SBK betting margin - 1.17%
  2. Unibet betting margin - 2.48%
  3. MarathonBet betting margin - 2.54%
  4. 888Sport betting margin - 3.77%
  5. BetUK betting margin - 3.81%
  6. MansionBet betting margin - 4.00%
  7. 21.co.uk betting margin - 4.14%
  8. Virginbet betting margin - 4.20%
  9. William Hill betting margin - 4.33%
  10. GentingBet betting margin - 4.55%
  11. Betfred betting margin - 4.55%
  12. Betway betting margin - 5.05%
  13. Quinnbet betting margin - 5.35%
  14. Netbet betting margin - 5.66%
  15. Boylesports betting margin - 5.71%
  16. bet365 betting margin - 5.75%
  17. BetVictor betting margin - 6.22%
  18. Parimatch betting margin - 6.22%
  19. Betfair betting margin - 7.04%
  20. Paddy Power betting margin - 7.35%

Extra Features

Lastly, we look at what unique features a sports betting site has to offer. Is there live streaming of sports to watch after having a wager on the action? What about deals like free bet clubs and acca insurance for existing users? And can users cash out on their bets?

When ranking online sports betting sites we also factor in any additional features or functions, such as in-play betting, live streams, acca insurances, betting tips, community forums, etc.

Best Welcome Bonus - Betfred

Betfred is one of the longest-running sports betting sites in the UK.

The best thing about the Betfred welcome bonus is that there are no lengthy wagering requirements. You get the £30 free bet credited to your account within 10 hours of settling the qualifying bet and you then get 7 days to use the free bet.

Best Selection of Sports - bet365

The sports on offer include mainstream ones such as football, tennis, rugby, motorsport, cricket, boxing, horse racing, American football, and golf.

In addition, there are also some more obscure sports such as Gaelic football, badminton, bowls, table tennis, e-sports, and virtual sports. You can also bet on novelty events such as the result of political elections and results of TV votes such as Love Island.

Unibet sweeps up the award for best free bets due to their fantastic existing customer free bet offers and rewards. The In-play Free Bet Club gift punters with a £10 in-play free bet every week if they place five or more £10 in-play bets between Monday and Sunday. Unibet also offers frequent loyalty bonuses such as £40 in free bets when you bet £10, so keep an eye out for these amazing bonuses.

Best Loyalty Program - Paddy Power

Paddy Power has an excellent loyalty program for existing players, as you would expect from one of the best known and well-respected sports betting sites in the UK. The slogan for their loyalty club is “More than just free bets” and that is true. Paddy Power does offer free bets on a frequent basis, but they also offer exclusive live events, monthly draws to win luxury holidays, discounts for retail stores and restaurants, random gifts that are posted to your home address (optional), and free food for members from exclusive food stands at sporting events. No other online betting site offers such a wide range of bonuses and promotions.

Best Betting Odds - Unibet

Unibet has the most competitive odds available online compared to other UK sports betting sites. They have large betting markets available, especially for the Premier League. The Unibet team are specialists in sports betting odds and take a smaller betting margin than most other sites, which means you get the best odds available online for most sporting events.

Best for Live Streaming - William Hill

They provide live streams of 100’s of sporting events each month including major events such as Premier League football matches, ATP Tennis, NBA Basketball, NHL Ice Hockey, etc. They also live-stream dozens of horse races every day, so you can always be assured that you can get some live-stream betting action on William Hill TV.

Alternatively, you can listen to William Hill's free Racing Radio for live commentary, tips, interviews and much more.

Best for Odds Boosts - Betfair

Although many online sports betting sites offer odds boost promotions these days, Betfair still leads the field. All players can boost the odds on three horses or greyhounds per day, with a maximum stake of £25 per bet. All you need to do is sign up and qualify for the ‘My Betfair Rewards Basic Package’ to get the three ‘My Oddsboost’ tokens sent to your account daily.

Best betting exchange - Betfair Exchange

A betting exchange is an alternative to a standard online sports betting site. The main difference is that a betting exchange allows you to compete against other customers, not a bookmaker. This means that as well as place bets, you can also lay bets. In other words, you can lay odds for other customers to bet on. 

Betfair is by far the biggest betting exchange available online, which means you have way more choice in terms of markets covered and more competitive odds. Many bettors prefer Betfair Exchange to the Betfair Sportsbook as you can get more value from the odds that are on offer. Betfair takes a small commission of 5% on every bet placed. 

Best New Betting Site - 21.co.uk

The final award is for the best new betting site and this year it goes to 21.co.uk. The sports betting site was only released in the UK in May 2021, so it’s very much the ‘new kid on the block’ when it comes to UK-based online sports betting sites.

But that doesn’t mean it doesn’t offer some serious value. With a good welcome offer, a decent number of sports and betting markets, live in-play betting, and ongoing promotions, 21.co.uk is right up there with the big players in terms of what is on offer.

21.co.uk scores very highly for its mobile app which is superb in terms of designs and functionality. Definitely, a sports betting site that is worth checking out if you’re looking for somewhere new to play.
