Why We Need To Compare Our Bookmakers 

Undertaking betting sites comparison ensures that punters are only taking advantage of the very best markets, odds, promotions and features. While all bookies will claim to deliver the most appealing services, it is really the opinion of others that matter. Our head to head battles between the leading bookies makes it clear and obvious as to which sites score highest in specific areas. Our experts know exactly what to look for, which is demonstrated by our in-depth bookmaker reviews.On the face of it, betting sites will look very similar to the naked eye. However, check out our betting sites comparison and you will quickly see just what separates the best from the rest.

How Do We Review & Compare Bookies

Punters can trust that our betting site comparisons are accurate, with our experts having thoroughly tested bookies in question. We register an account, before taking an in-depth look at the markets and features on offer. There are a number of areas in which we focus upon, including odds, sports coverage, promotions and payment methods. 

With no one betting site being the same as another, our head to head battles help punters in deciding which is best for them. Only bookies licensed and regulated by the Gambling Commission will be compared, while all sites are completely safe and trustworthy. When comparing betting sites, we consider the following factors:

Available Markets

The best betting sites in the UK today cover a large number of different sports. While football, horse racing, tennis and cricket are among the most popular, the likes of Esports, basketball, MMA and darts are growing quickly. Our top ranked bookies deliver 30+ sports in total, with pre-match, live and outright markets being available to punters. Meanwhile, many bookies also now offer virtual sports markets, as well as covering events from the world of politics and entertainment.

Odds Value

The prices found at betting sites will determine how much punters earn from winning bets. As such, odds are hugely important. Often overlooked by punters, it is fairly simple to compare the odds between two bookies. Available to view in fractional, decimal and American formats in most cases, even the smallest of difference in price can be significant. 

Betting App

A significant proportion of bets are now placed via mobile devices. This is why a number of bookies have developed and launched dedicated betting apps. Apps make betting on the go quick and simple. Available on iOS and Android devices in most cases, apps come with the same amount of markets and features as found on desktop. For bookies that do not offer a betting app, their betting site must be accessible through mobile browsers.

Betting Features

The user experience can be enhanced at betting sites if features such as live streaming, bet builder, cash out and live betting are in play. Live streaming makes it possible to watch sporting action, while cash out is useful for settling bets early. Be sure to keep an eye out for such features, with most bookies having recognised their importance. 

Betting Offers and Promotions

While not being the be-all-and-end-all, betting promotions can certainly help punters in achieving their goals. Most online bookies offer some form of welcome bonus, helping to attract new customers. Meanwhile, those already signed up can take advantage of a variety of ongoing offers. Free bets, price boosts, acca insurance and money back specials are among the most popular. Betting promotions come with terms and conditions, which will effect their appeal. 

Payment Methods

In order to fund your betting activity, money must be deposited to your bookmaker account. A host of payment methods can be found online today, including Visa, Mastercard, PayPal, Skrill, Apple Pay and bank transfer. Ideally, both deposits and withdrawals will be processed quickly and without any fee. The top betting sites also ensure that payment details are never at risk from third parties.

Live Betting

Live betting involves wagering on sporting events that have already started. Examples include betting on the next football team to score or the tennis player to win the next game. This is a hugely popular form of betting, with many finding it easier to find value here. Odds change on a regular basis, depending on what is happening on the pitch, court or track. 

Customer Support

In an ideal world, punters should be able to contact members of staff day and night. Whether it be because of a technical issue or assistance is required surrounding a bonus or active bet, bookie’s today offer support via telephone, email, live chat and social media platforms. Response times must be good too, ensuring that punters can focus on betting. Most betting sites also come with detailed FAQ pages, providing information surrounding registration, responsible gambling and banking.

Which Site Has The Most Betting Markets? 

As we briefly mentioned above, bookies must cover a variety of sports. Betting customers today have a more diverse set of interests than ever before. It is not simply football and horse racing that are wagered upon. This is demonstrated by the number of additional events and competitions covered from around the world. Betting sites comparison clearly shows which bookies perform the best in this area. Those only offering a small number of sports will find it difficult to compete. When it comes to markets, 888Sport offers great variety, with some 30+ sports being found in total. Let’s take a closer look at some of the most popular sports found at the best betting sites today:


Whether it be action from the Premier League, Champions League or World Cup, all UK bookies must ensure that they deliver a host of betting options surrounding football. Our top betting sites cover leagues and cups from around the world, with pre-match, live and outright markets being available. A number of promotions are available to football fans too, along with features including live streaming, bet builder and virtual betting. Popular football betting markets include 1×2, total goals, first goalscorer, half time/full time and handicap. 

Horse Racing

Horse racing and betting go hand in hand. Meetings from across the UK & Ireland are available daily, along with international races. Betting on horse racing online is made more appealing thanks to promotions such as best odds guaranteed and extra places. Meanwhile, a large number of races can also be viewed live at selected betting sites. Punters can view the age and weight of runners at most betting sites, along with other useful information. 


It is not only the four Grand Slams that attract attention from punters. Tennis tournaments are found at betting sites weekly throughout the year, with a host of pre-match, live and outright markets being available. Popular markets include correct score, 1st set winner and outright tournament winner. Many matches are available to watch through live streaming services, aiding those placing in-play tennis bets.


Cricket is another sport that regularly features at most betting sites. Test, One Day and T20 matches are found, involving both international and domestic teams. Competitions such as The Ashes, Indian Premier League, World Cup and The Hundred feature heavily. Here, popular markets include total runs, leading wicket taker, method of dismissal and even to win the toss. 


Competitive gaming has grown rapidly over recent years. As a result, it comes as no surprise that the majority of bookies now accept Esports bets. Titles including CS:GO, League of Legends, Call of Duty and FIFA now feature on betting sites, with many matches being available to watch live. The best Esports betting sites even accept cryptocurrency payments, as well as offering skins betting options.  

The Best UK Betting Odds

Betting odds comparison sites quickly show which bookies are offering the best prices on sporting events. However, our experts have done the hard work for you, with our betting sites odds comparison allowing us to recommend only the best bookies. Punters will want to know that they are taking advantage of the very best odds. Doing so means that the maximum possible winnings are earned. 

Odds can be displayed in a number of formats. At most betting sites, this is either fractional, decimal or American. Having compared the odds at all available betting sites, we can safely say that Kwiff is among the leading bookies. Prices are already competitive, with punters then being able to take advantage of their “Supercharge” feature. 

The Importance of Mobile Betting and Betting Apps

Bookies today must cater well for the needs of their mobile customers. For those that are constantly on the go, accessing betting sites via a smartphone or tablet is vital. Some can now do so through dedicated mobile apps. Betting apps are hugely efficient in most cases. With touch/face ID login, notifications and customisable pages, it should come as no surprise that apps are the preferred platform for many. Available on iOS and Android devices, download links can be found on the App Store and Google Play Store, respectively. While many bookies have invested in the development of betting apps in the past, it is the QuinnBet app that we recommend.

What Betting Features We Compare

In terms of what separates the best betting sites from the rest, we compare a host of features before delivering our verdict. So, at our top ranked betting sites, punters can rest assured that bookie’s score highly in the following area:

  • A large number of pre-match, live and outright sports markets
  • Competitive odds across all sports, allowing punters to find value
  • A variety of promotions, including for both new and existing customers
  • Additional features such as live streaming, cash out and bet builders
  • What mobile betting options are available? App vs browser
  • Is 24/7 customer service available? 
  • A good mix of payment methods, including bank cards, e-wallets and prepaid vouchers
  • Betting sites must be easy to use, whether on desktop or mobile

Which  Bookie Has The Best Promotions? 

Betting promotions can undoubtedly help punters in maximising winnings and minimising losses. While price boosts, acca insurance, early payout, best odds guaranteed and money back offers are among the most common, T&Cs tend to determine which are the most popular. At this time, the following are among the best promotions available to punters in the UK:

  • SkyBet Free Bet Club – Existing customers at SkyBet can claim a £5 free bet when placing £25+ worth of qualifying bets. One free bet per week is available, with tokens having no expiry date. As with the majority of such offers, only winnings made will be available to withdraw. The stake is returned to the bookie. 
  • Paddy Power Beat the Drop – This unique game from Paddy Power is available to both new and existing customers. Players must answer a host of questions, based around football matches. Players must choose whether to go all in or split the pot, with any remaining funds after all questions have been answered being pocketed. A prize pool of £250,000 is available to new customers, before £1,000 can be won daily. 
  • MansionBet ACCA Boost – Punters at MansionBet can earn a bonus worth up to 60% of their accumulator winnings. 4+ picks are required to qualify, with a 14+ fold acca being needed to claim the maximum bonus. Total odds of 5/1 must also be met, with only pre-match markets being eligible. 
  • Betfred Double Delight/Hat-Trick Heaven – For football fans, this offer from Betfred is well worth taking advantage of. Place a pre-match bet on the first goalscorer market in order to be in with a chance of qualifying. In the event of your pick scoring two goals, punters will earn double the winnings. Should they score a hat-trick, winnings will be trebled.

Payment Methods for Deposits and Withdrawals

Depositing and withdrawing money at betting sites should be quick, convenient, secure and free of charge. Punters today can take advantage of a large number of payment methods. However, the specific options will vary between bookies. So, when selecting how to deposit and withdraw funds on betting sites, be sure to consider the following factors:

Processing Times

There is no use selecting a payment method if you are forced to wait for an age for transactions to be processed. Deposits at betting sites are more often than not instant. However, withdrawals can take up to 10 days, depending on the bookie and payment method. Ideally, this will be much quicker, with some e-wallets taking a matter of hours. 


When operating online, punters must feel safe. Part of this surrounds transferring money. Whether you are using a bank card, e-wallet, prepaid voucher or another platform, deposits and withdrawals must be carried out securely. Bookies have a number of tools in place to ensure that this is the case, including SSL encryption and firewalls. Third parties must never gain access to sensitive information.


Sometimes, withdrawals from betting sites will come with a processing fee. In most cases, bookies will cover this. However, those that charge punters for taking home winnings are not likely to appeal. This will again depend on the payment method used. 

Bonus Eligibility

When depositing funds for the first time, some payment method will not be eligible in terms of qualifying for a welcome bonus. For example, many bookies state in their bonus T&Cs that e-wallet payments are not eligible. This is why it is so important to read the small print before signing up and depositing.

What is the Best In-Play Betting Site in the UK?

In-play, or live, betting is now the chosen method of wagering for many punters. Betting on sporting events that are already underway opens up a variety of additional options. With odds regularly fluctuating, those who can place a bet at the right time often reap the rewards. It is difficult to find a betting site that doesn’t offer live markets today. However, the best in-play betting sites will come with attractive odds, live streaming, cash out and multiview features. For this reason, we recommend Betfred. The bookie offers in-play markets on a host of sports, including football, tennis, cricket and basketball. Their live betting platform is also easy to use, with streaming and useful statistics accompanying many markets.

Betfred Football betting

Which UK Bookies Offer Live Streaming

Live streaming has already cropped up on numerous occasions on this page. While not being available with all online bookies, it is one of the most popular features around. When it comes to live streaming, events from football, horse racing, tennis, Esports and select other sports will generally be available. However, the qualifying terms differ between bookies. On some sites, simply having a funded sportsbook account will be enough to watch live action. However, on other sites, a qualifying bet must be placed on the specific event. 

There is no doubt that live streaming has been one of the greatest features introduced over recent years. While it is exciting to watch your favourite sports teams and players, more importantly, it can benefit your betting. Especially when it comes to in-play odds, live streaming gives punters a greater understanding of who may come out on top. So, if live streaming is something you require, be sure to sign up with a bookie offering such a service. The likes of Bet365, Paddy Power, Betfred and 888Sport all deliver live streaming opportunities.

Customer Support

While it may not be at the forefront of punters’ minds initially, you will be surprised as to how often support is required at betting sites. Agents are generally on hand via telephone, email and live chat, however this differs between bookies. The best betting sites will respond to issues and questions quickly, as well as in a friendly manner. This cannot always be said online today, with some bookies only being available between set hours. 

Top bookies are now active on social media platforms, including Facebook, Twitter and Instagram. This offers customers another avenue to get in touch. Meanwhile, detailed FAQ pages are found on both betting sites and apps. Here, useful information can easily be read, which often means that additional assistance is not required. With vast experience and a host of customer service features, William Hill is one bookie to excel in this area.

Best Sites Per Sports Market

Most bookies will cover a variety of sports. However, some will specialise or place a greater emphasis on certain sports. So, whether you are football crazy, can’t get enough of horse racing or are one of the many to have got into Esports, the following are the best betting sites per sport:


SpreadEx is a top bookie when it comes to football betting. Here, a huge number of leagues and competitions are covered. With excellent in-play options, it comes as no surprise that SpreadEx is the UK’s leading spread betting site.

Horse Racing

You will do well to find a better site for horse racing betting than Bet365. With live streaming, a host of promotions specific to the sport and competitive odds, customers here can also look at detailed pre-race information before backing their favourite. 


We can recommend Paddy Power to cricket betting customers. The bookie delivers markets on international and domestic matches, including from the County Championship, IPL and World Cup. 


Tennis is a very popular sport to bet on. MansionBet delivers a host of markets and features surrounding the sport, making it an attractive bookie for tennis fans. With thousands of daily in-play tennis markets, as well as generous promotions, it is little wonder the bookie attracts punters throughout the season.


Whether it be Union or League, rugby has quickly become one of the most popular betting sports in the UK. 888Sport is undoubtedly one of the best bookie’s for rugby betting. With excellent rugby coverage and competitive odds, those who love last-gap try or a bit hit should certainly check them out.


Looking to bet on the winner of the Masters or which player will be leading The Open after the first round? Golf betting sites are available in their droves today, with Coral being one of the top platforms. Paying out on extra places on many tournaments, Coral also offers excellent odds and a range of markets.


CS:GO, League of Legends, Dota 2 and Overwatch help to make up the Esports scene. A number of titles can now be bet on through online bookies. Betway has a dedicated Esports betting page, which includes a specific Esports welcome offer.


Snooker may not be one of the first sports you think of when it comes to betting. However, those who have a good knowledge of the players, tactics and format regularly back their favourite players. 10Bet is one of the best betting sites for snooker, with regional and international tournaments being covered.


Formula One is the pinnacle of motorsport for many. Betfair offers a host of markets on the sport, including outright championship winner. Bets can be placed during races, with Betfair’s odds regularly being the best around.
