Advertiser Disclosure
Every online gambler deserves a safe and fair place to play. Our mission at Gambling.com is to create a safe online environment for players through free, impartial and independent reviews of the UK's best online gambling companies so that you can play with confidence and security. All ratings and reviews are made independently of the operator by our team of gaming experts and with every company being fully UK licensed they can be trusted to offer fair play. We accept compensation from the companies advertised on this page and this may affect the brand positioning. We endeavour to continuously update this list so we can bring you the most current sites and the best available offers but we cannot review every site in the market.

How Do We Review the UK's Best Betting Sites?

Our review process is the most robust in the marketplace. We go through the sign-up process personally, deposit funds and test every betting site from bet placement, cash outs, bet type and bet settlement to ensure it's the best possible experience from start to finish.

Not every betting site is the same. Some will be strong on horse racing betting, some on football, some major in tennis, cricket and golf. Then there are some betting sites that provide the best service on markets outside of sport, such as specials markets and politics.

We aim to find the best betting sites and apps that combine all factors, add value to your experience and importantly play fair when it comes to customer service and security. You can be sure all are fully licensed by the UK Gambling Commission. If they don't match up to our expert team's expectations, then they simply don't make the cut and they shouldn't get your business. Here's what we ensure is covered when we review betting sites:

  1. Bonus Offers and Free Bets

    In a competitive marketplace you can rightly expect a clamour for your business and the first interaction with your newfound betting site should be a rewarding one. We break down the Terms and Conditions attached to any sign-up offer, deposit bonus or free bet to ensure it is genuine and achievable for those who want to take it up. We cover wagering requirements, qualifying attributes and provide the information you need to avoid any confusion. There is nothing more frustrating than not getting what you signed up for and thanks to our team of industry experts we make sure that doesn’t happen.

  2. Market Variety

    There is little point signing up to a new betting operator and not being able to place a wager on something that you can bet on with others but not at your new bookmaker. Market choice is important to us and it should be to you. Our recommended sites deliver choice and access across all genres, from the Cheltenham Festival in horse racing to elections in politics, TV specials to prime-time international events.

  3. Payments

    Never have so many options been available to UK betting customers when setting up an online betting account. The traditional method for online transactions of Credit and Debit Cards are still the most commonly used, as you would expect. But these days the use of eWallets like PayPal, Skrill, Neteller and other newer options are open and accessible with most operators online. Our in-depth sportsbook reviews detail these options in full transparency for every betting site we recommend. We explain the monetary limits, deposit and withdrawal times for each service and what to do when you need to change from one to the other. We also take time to consider each option as the initial transaction for a user. Some operators will allow eWallets as a first deposit option but will not qualify that deposit for a sign-up bonus, free bet or deposit match and this is something to be aware of when signing up and placing your first bet.

  4. Unique Features

    The same old experience isn’t enough for a company to be classed as one of the best UK betting sites. We want to see new technology, competitions and interactive elements in a betting site which truly makes it a first-class experience.

  5. Industry Reputation

    We care what existing customers think of the most popular betting sites we review and break it all down here on Gambling.com. Our team of reviewers take time to check the forums, test the customer service and delve into pain points that existing customers have with betting operators. Whether it is a promotion that didn’t deliver, a new product experiencing teething problems, or a disputed bet that wasn’t handled properly you can trust us to know and have an opinion on it. We also take time to fully appreciate the high points of these elements, which site is the quickest to assist a customer, has the best live chat, the best ongoing rewards and the most innovative approach to user experience. Existing customers are a great guide to which brand is going to suit you best and we take that to the heart of our recommendations.

  6. Security and Support

    We ensure that all our recommended betting sites provide a secure transactional environment for payments, document storage, betting history and personal details. We test their customer support, their response time and efficiency in dealing with you as the consumer in a fully compliant and, most importantly, a regulated and licensed environment.

  7. Licensing and Legislation

    Every single betting site we recommend is fully licensed by the UK Gambling Commission. We display license numbers, corporate details, customer support information and everything you need to know to be certain that you only interact with the safest and most transparent sportsbook betting operator options online. If they don’t match up, they simply don’t appear on our site.

  8. Mobile Experience

    Betting on the move with online bookies is what punters have come to expect from the best online betting sites in the UK. The days of having to make a phone call or having to find high street betting shops, filling in the slip and waiting in line are long gone. Nowadays the leading online betting operators will have mobile optimised websites and seriously clever apps that allow you bet with one or two clicks wherever you are and whenever you want, signal permitting! We test the mobile experience to the hilt and if it doesn’t deliver, we let you know.

Sign-Up Process

We also measure a bookmaker's sign-up process when rating their product. In recent years the sign-up process for an online betting site has become more challenging but that is truly in the customer's favour. The customer verification process with the best online bookmakers is streamlined, simple and secure and once completed allows you to withdraw faster, utilise more payment methods, have access to better promotions and feel secure in your relationship with your chosen bookmaker.

Expect to provide the following information as a minimum and anything unique or different is fully disclosed in our expert reviews:

These days all this information can be provided directly online - uploading documents to a secure portal within the operator's betting website is simple to do. Customer Support can verify an account in minutes and there is no delay when signing up with the best betting sites.

It makes sense to have this information to hand when signing up. If you prefer to provide it when making a withdrawal following a win, as some operators will allow, it can be a tiresome experience when all you want to do is cash out your winnings.

Odds and Pricing

To some, the competitiveness of the prices and odds offered by a betting site is the sole reason for choosing one operator over another. The UK marketplace is fiercely competitive and variances in the odds of a single event can be startling. That's why it often pays to have more than one account. Having several accounts across a variety of the best betting sites can be extremely handy if you want to get the most value for every bet you place online.

Consider the same scenario if you were shopping online for a particular item. Its price may vary at several different online outlets and whilst you may be prepared to pay a little more to get the item quicker or to receive loyalty points at a certain outlet, it is still an important decision that you have to make when other choices are available to you.

Betting online is very similar. Whilst Best Odds Guaranteed or Enhanced Odds are available with many online operators, our reviewers try to establish a pecking order with our recommended best betting sites in terms of their prices and odds. Do they match up to the best most of the time and do they aim to lead the way with the markets that are most common and expected?

Our reviews focus on this and give you the information you need to make an informed choice. However, there is no substitute for shopping around and having several operators available to you from our best betting sites list.

Streaming Options

Having a bet can be a great thrill. However, if you're on the move and not viewing the results unfold, it can take away from the experience. Most betting sites now offer the option to watch the action via a live stream once you have placed a bet. A small minimum stake applies but for a wager of as little as 50p, you can watch the result of your bet unfold from the moment you get involved until the end.

If this is crucial to you, be sure to check out our best live streaming betting sites that provide this service with the smartest user experience possible. There are many to choose from and the quality varies from site to site.

User Experience

The biggest issue faced by the UK betting audience is getting the ideal user experience wanted from an online betting site. Are the sports you want to bet on easy to navigate to? Does the operator lay out the options in a way that makes finding what you want simple and efficient?

Can you track your bets, check your profit and loss or take an early Cash Out when you want to change your mind? And if you want to withdraw how long does it take?

These factors are paramount and a huge focus for our review team when they deliver a final verdict and score on a betting site. The look and feel and style of a site might be skewed to a certain type of sports bettor and you will see in our reviews that we pay attention and know the difference.

Understanding what you need is important and knowing that we care about that will help you to make the best choice. Remember, it is your choice and not ours - the right betting site is out there, maybe even a combination of two or several sites is what you need to get every facet covered and unlock free bonuses.

Take the time to read over our reviews and find the best betting site for you, from user experience over mobile versus desktop or tablet, the payment options, customer service and loyalty schemes, the bonus on offer and the markets and pricing.

Our Team of Online Betting Industry Experts

Our bookmaker reviews team is made up of regular active sports bettors, ex-betting industry employees, traders and odds compilers, and customer support staff. No one person can cover all aspects of an online betting site review, so we pool resources to make the best betting site guide on the internet.

We cover every bonus and sportsbook change as it happens and you can be sure that we have the most comprehensive rankings, industry information and detail available at all times, so choosing the best betting site is easy for you.

This is true whether you are just starting out with online betting or a hardened pro who wants VIP support and bells and whistles from your online operator.

The Gambling.com Group team has rightly received awards for this process from industry peers and panels. We pride ourselves on transparency and dedication when it comes to informing our users. We remain committed to backing up our process and our way of working by improving and striving for progress through recruitment, customer feedback and information gathering that other sites can only attempt to emulate.

Best Betting Sites Across Popular Sports Betting Markets

Our reviewers know what you want from your sports betting experience because they're passionate about all things sports betting. Whether you are having a punt on popular sports like horse racing, football, cricket, tennis or golf, American sports like basketball, ice hockey and American football, or the likes of rugby, snooker, boxing or cycling, we have plenty of sports gambling experience in our ranks, which equips us to recommend the best betting site for your favourite sport.

Best Football Betting Site Options

When reviewing a football betting site and comparing competitors, a number of important factors are taken into account. Firstly, any sports betting site worth recommending should have plenty of markets to choose from.

The best football betting sites we recommend offer the basics like win/draw/win, first goalscorer and anytime goalscorer, both teams to score, half-time/full-time, and handicap betting markets. The best football bookmakers online also offer hundreds of other fun markets and betting options, aside from just the traditional ones. Appealing features like in-play football betting, live streaming, cash out and competitive odds are top of the agenda for many and we make sure to check these out thoroughly.

When evaluating a football betting site, it would be remiss of us not to compare and contrast each welcome offer, free bet offer and other promotions, to make sure a football bettor is getting the best deal they can.

Top Horse Racing Betting Sites

Horse racing is one of the most popular sports to bet on worldwide and there are a plethora of betting sites out there to analyze and evaluate. That's why our horse racing betting experts have done the hard work for you.

We know which bookies offer the most competitive betting odds and stay right up to date with the online sports betting scene. It's imperative to keep track of newcomers as well as established betting sites, to make sure they're included in our list of the best horse racing betting sites if they provide an excellent service for those who enjoy a punt on the horses.

We also ensure that any betting website we recommend is safe, legal, and is regulated by the UKGC.

Live betting and streaming are crucial features for many horse racing bettors, and we make sure to look out for these when assessing the best betting sites.

Best Cricket Betting Sites

Any UK bookmaker aiming to compete with the top sportsbooks should offer betting opportunities on cricket. The best betting sites you see listed here all offer cricket betting odds.

The best cricket betting sites cater to punters who are interested in different formats of the game like Twenty20, one-day international and test matches. At Gambling.com, you won't find an online bookie recommended for their cricket offering unless they offer a myriad of betting options.

We work only with trusted sports betting sites and make sure that bettors get the best welcome bonus or free bet offer they can when signing up to one of the best betting sites for cricket.

What the Best Betting Sites Offer

The best betting sites will invariably offer a bit of everything that is important to the user. Great market coverage and excellent customer service, aligned with speed and entertainment, will be at the core of all online betting platforms.

When we decide who is the best and what marks out a serious betting operator from the rest, we want the following things to stand out:

  1. Streamlined, secure and straightforward sign-up process.
  2. No hidden requirements, ease of process and ability to complete in a one-time efficient sitting is paramount.

  3. Sign up bonus/free bet/deposit bonus
  4. An introductory offer that is accessible, achievable and valuable. No hefty wagering requirements, difficult terms and conditions or hidden loopholes.

  5. Mobile experience and multi-platform use
  6. How does the betting site work when on the move, what is it like when under the most pressure - i.e. 3 pm on a Saturday afternoon! Can you access on a laptop, phone, and tablet with equal usability?

  7. Loyalty promotions and rewards
  8. How does an online bookmaker cater for loyalty and rewards if you are a regular player? VIP clubs, free bet schemes, bet insurance and bonuses. What level of play is needed to qualify for additional benefits and how difficult is it to achieve them?

  9. Payments
  10. From debit card deposits to eWallets, how long does it take depositing into your new account, what methods can you use and what are the time limits? More importantly how long does it take to withdraw your winnings? Speed of access to funds is crucial when deciding the best betting site to choose online.

  11. Markets and In-Play betting
  12. Many sites will be comparable in terms of sports and betting options they offer but do they match up when it comes to price competitiveness and In-Play odds? Are the In-Play options robust and varied, do they allow Cash Outs and quick turnover on the sports you want? Can you choose between decimal and fractional odds at the click of a button?

  13. Specialisation
  14. Is an online betting operator the best for football betting, tennis or horse racing? Do they cover American sporting events like NFL or basketball better than others? We call out the specialties and the deficiencies to make sure you are in the right place from the get-go. You don't want to be faced with a predominantly online casino site that has just added a sportsbook on the side as an afterthought.

Bonus Offers and Free Bets

Free bets and bonus offers are an integral part of any betting site. Bookies are constantly competing with one another to draw in new clients, and thus they will try and edge each other out with an attractive welcome bonus or the proposition of a free bet. However, it's important to take a few things into account, such as welcome offer wagering requirements or how long a free bet will be valid once it's issued. As a general rule, punters will have seven days to use a free bet which has been issued to their account, but this can differ from one betting site to another.

The best betting sites with free bet offers will apply a multiple of your initial deposit to your account in free bets, which you can then use during a certain period of time across their platform. In general, you can use this on any sport if it's a free sports bet, but on occasion, it could be a casino bonus. Some bookmakers will offer different free bet variants, such as a multiple bet where you must choose three or more selections. Be sure to check the T&C's before joining up with one of our recommended betting sites to ensure their Bonus Offer or free bet suits your needs.

Variety of Betting Markets

Whether you're a seasoned pro or just a casual punter, having a wealth of options to bet on will come in handy during your time with any given operator. Naturally, some bookmakers will offer certain markets that others don't. For example, Bet365 famously offer Asian handicap markets on football betting, something that plenty of other betting sites don't have on their platform. This gives them an edge in this aspect.

Looking for sports bonus? Find all Bet365 Bonus Codes right here on Gambling.com.

Nowadays online bookmakers offer a slew of markets across multiple sports and any operator which does not offer markets on one of the major sports such as football, horse racing, NFL or golf will not feature on our recommended betting sites list. Any sport that can be aired on TV should be covered, but it's not just sports. Bookmakers have delved into more niche topics, such as political betting or TV specials betting. Paddy Power are one of the leading bookmakers when it comes to offering these more specialist markets or novelty bets. We recommend taking a good look at each operator's markets before signing up with them!

Quality of Betting Site Platform

When it comes to the quality of a bookmaker's betting platform there are a couple of key factors that are non-negotiable for customers. First of all, a betting site needs to be easy to navigate and should not be complicated to use. There is nothing more frustrating than when you are searching for a bet that has been buried in the archives or the sport you desire to wager on can't be located within one or two clicks.

In an age where almost everybody has a smartphone, it's also absolutely vital that bookmakers offer a state-of-the-art phone application that's available on both iOS for iPhone and Android devices. These apps should be just as easy to navigate and offer the same features as their desktop compatriot and should offer the cash out functionality or live streaming service.

Great Customer Service

Just like with any service, when something goes wrong or you have any question, you should expect top-quality help from expert technicians. Thankfully, every operator on our best betting sites list on this page has a fully functional live-chat customer service option to help you with any queries you may have during your betting experience. However, you should be aware that during large sporting events such as the Cheltenham Festival or Champions League final there may be a delay when it comes to speaking with a customer service agent.

If a live-chat service isn't for you then don't worry, speaking to a customer service agent over the phone is also an option, with some operators even able to place a wager this way. There is also an email helpline for less urgent inquiries, but we recommend using the live-chat function for instant feedback and assistance. Rest assured, any betting site featured on our recommended list on this page has top-notch customer service in place.

How to Identify Fully Licensed and Legal Betting Sites in the UK

If we recommend a certain online betting platform then you can be sure it is fully licensed and legal to operate and accept your custom in the UK. If you are considering a certain platform to bet on sports and can't find it on Gambling.com, then beware. All of the operators you'll find on our site are fully vetted in person by our expert review team and we display all of their corporate information and bona fides as a matter of course.

Choose the team, individual or even the horse that you expect to win and want to bet on and select the price that is shown. Then choose the stake you wish to place on that outcome and confirm your wager and you will have placed your first bet.
