21.co.uk Welcome Offer - Our Verdict

21.co.uk has built a strong reputation with a solid range of sports betting markets and a slick and well-designed site. Its quick and easy navigation makes enjoying these markets easy. The sportsbook has an effective customer support service and a basic selection of banking methods for making deposits and withdrawals.

Licensed by the UK Gambling Commission, and owned by large online gambling group LeoVegas Gaming, 21.co.uk is a sportsbook that is local to the UK  and was built with the aim of catering to UK betting sites users. Still, this sportsbook offers LeoVegas Gaming's extensive market coverage, sleek design, superior usability and a seamless mobile betting experience.

We also found that 21.co.uk often updates its offers page to give players a chance to make the most of the markets, and in-play options give players the flexibility to bet as they see fit. Bettors outside of the UK will probably not find too much appeal in the 21.co.uk sportsbook. But if you are somewhere in Great Britain and looking for a state-of-the-art online sportsbook, you should not miss 21.co.uk.

For those wanting to learn more about this UK sportsbook, read our 21.co.uk sportsbook review to find out what it offers new and existing customers.

Expert Verdict Expert

It’s clear 21.co.uk put in-play betting at the heart of what they do, with their live betting markets being the first thing that greets you when you access the platform. Part of the LeoVegas group, you can be assured you are in the safest and most experienced of hands when it comes to online betting. Unfortunately, they do not have a distinct iOS or Android app, but this eye-catching site performs just as well on mobile as it does on desktop.

Player Verdict Player

21.co.uk is an exciting new sports betting brand which is designed to be super-quick on mobile devices, meaning that customers can find and place their bets in seconds. This is a betting site that focuses hard on soccer, horse racing and tennis, with customers able to place a Bet Builder or alternatively choose a pre-pack bundle and enjoy a same-game multi on the match in which you’re most interested.

21.co.uk Review

21.co.uk was launched in 2013 and is now owned and operated by online gambling giant LeoVegas Group. LeoVegas has successfully established itself as a dominant force in the European gambling marketplace. Originally founded in Sweden, the company has main offices in Sweden and Malta, and is traded on the Stockholm Stock Exchange. 21.co.uk is only one of many successful sites in the LeoVegas stable of brands, including, of course, flagship site LeoVegas, Royal Panda, LiveCasino.com, BetUK and many others.

The UK Gambling Commission (UKGC) regulates 21.co.uk to provide sports betting and casino products. The UKGC is one of the most respected gambling regulators globally and requires its licensees to adhere to strict player protection and data integrity standards. Players can rest easy knowing their personal details and finances are safe when playing at 21.co.uk.

21.co.uk Bonus Codes

The online sportsbook sector is a highly competitive environment. One method online sports betting sites use to compete and attract customers from rivals is offering exclusive promotions that can be claimed with unique promo codes.

A promo code is different to bonus funds. In the case of a bonus, any player who registers with a site will receive free bets or other rewards as part of their signup. The promo code is a set of letters and numbers that you can enter to claim a unique offer on the betting site. New players and those who already have an account can use promo codes, depending on the offer.

An example of a promo code would be WELCOME100. In this case, the promo code would give you the chance to claim a £100 bonus when you sign up to a site. This code is just an example, and entering it on 21.co.uk's sportsbook will not reward you with anything. When you click on the links in this review, you will be able to find promo codes and betting offers at 21.co.uk sportsbook.

Below are some examples of promo codes you can occasionally find on 21.co.uk and other online sports betting sites:

  • Exclusive: This bonus code is only available to a selected group of players.
  • Deposit: A promo code used to redeem a bonus offered with a deposit.
  • Sport Specific: Codes that apply only to certain sports and events.
  • Event Specific: A bonus code that can be used to bet on a specific event. For example, the FA Cup or the US' Super Bowl.
  • Casino Code: A promotion offered to use on the site's online casino or live casino games.
  • Risk-Free Bet: A refund offer in which the stake of your first bet at a site is refunded if it loses.

However, not every casino game requires a casino bonus promo code. Click on one of the links on this page to find the latest bonuses and promo codes on the 21.co.uk site.

21.co.uk Welcome Offer

21.co.uk sportsbook knows how important it is to incentivise new players to sign up to its site. So, like most online betting operators, it greets new players with the best betting welcome offers. Think of it as the bookmaker's way of welcoming new customers. So it is important to note that only new customers that are signing up can claim this type of bonus.

There are various types of welcome bonuses offered by 21.co.uk and other sportsbook operators. We listed some common offers below.

Free Bet Offers

Free bet offers are one of the most common types of welcome. When you claim a free bet offer, you will have a designated amount of bonus money you can use awarded to your new account. You usually have to deposit a certain amount to receive the bonus (e.g., deposit £20 to get a £10 free bet).

Note, that usually free bets have time limits and must be wagered on specific sports betting odds, so be sure to read the terms and conditions on the 21.co.uk website before redeeming an offer.

Deposit Bonus Offers

The deposit bonus is a welcome bonus that rewards you for signing up and making your first deposit. Typically, these will be a match of a percentage of your deposit. So, for example, a sportsbook may reward you with a 100% bonus amount of your deposit. You would therefore have your deposit and an equal amount in bonus bets to wager.

These bonuses often come with wagering requirements. This is a designated amount you have to bet before you can cash out winnings. Be sure to check 21.co.uk's bonus terms for more information.

No Deposit Bonus Offers

This is the rarest of all the offers mentioned. With the free bet no deposit bonus, you are rewarded simply for signing up with a sportsbook. A bookmaker will then fund your new account with a set free bet amount after you have completed the registration process. Although these bonuses are hard to find, they are definitely worth shopping around for!

21.co.uk Desktop Experience

When using a sports betting site, getting to the sports and markets you plan to bet on without unnecessary delays is essential. We were pleased with 21.co.uk's navigation system, which stands out from the crowd for being straightforward and effective.

The site has a dark blue background with menus and details highlighted in white and light blue. All of the markets and sections stand out clearly. It is possible to find the section you are looking for with just a few clicks through two separate menus across the top of the page. Or, through the left-hand side list, which groups all the various sports into categories.

21.co.uk App

21.co.uk sportsbook does not provide a downloadable betting app to customers who bet through mobile. But thanks to its site built with HTML5 technology, the website is responsive and optimised for mobile browsers. So you can enjoy the full range of markets, bets and features offered on the 21.co.uk website from any place, at any time.

The 21.co.uk mobile site runs smoothly, and there is no lag apparent across a range of devices and operating systems. Mobile users will find they can bet on the same markets and betting features available through the desktop site. The slick design of the site is effective on smaller screens, as the clear menus and layout make it easy for customers to check out the sports betting odds on the move without the need of any betting apps.

21.co.uk Registration Process

As a fast-growing betting site, 21.co.uk sportsbook aims to attract new customers continually. As a result, the sportsbook has set up a straightforward registration process. Follow these quick and easy steps for signing up, and you can be placing your bets in minutes:

  1. Click on any 21.co.uk link you find in this review. You will then be directed to the 21.co.uk website.
  2. 21.co.uk has several Join buttons that are coloured in sky blue and very visible on the site's dark backdrop. Click on one of these buttons to start the registration process.
  3. Fill in your email address, and pick a username and password. Add any further contact details required.
  4. Enter an active 21.co.uk promo code if you have one. If you don't, simply continue your registration process. You will still be able to claim bonuses that do not require a promo code.
  5. Head to the cashier section, select a deposit method, enter the amount you wish to deposit and follow the quick steps to fund your sportsbook account.
  6. Check if the bonus was credited to your account balance. Contact customer support in case of any questions.
  7. Upon completing your deposit, you will be redirected to 21.co.uk's lobby. Search for your markets such as the NBA betting and place your bets.
  8. If your wager is a winner, go to the cashier withdrawal section and follow the instructions to cash out your winnings.

21.co.uk Account Verification

Account verification procedures may sometimes appear inconvenient, but they represent a significant aspect of ensuring safety for all players. These measures help prevent underage gambling and other platform abuses, such as money laundering and fraud.

The verification process will require you to prove your identity, and this is usually done by uploading the relevant identity documents in e-form. The documents you could be asked for are listed here.

  • Photo ID (passport, driver's license or another formal ID)
  • Proof of address (a recent utility bill)
  • Proof of payment method used (a bank statement or photo of your credit card)

You can either email your documents to the sportsbook's support team or upload them to the website yourself through a dedicated area on the 21.co.uk website. Once you have uploaded the correct documents, your account will usually be verified within 48 hours or less. You can still deposit and place bets while the verification process is taking place. However, you must have your account verified to cash out.

21.co.uk Payment Methods

Using your preferred payment method is an integral part of choosing a sportsbook. Bearing this in mind, we were a little disappointed with the range of payment options available on the 21.co.uk betting site.

The site details only four options: Visa, Visa Debit, Visa Electron and Mastercard. It is disappointing that a broader range of payment options is not available, particularly when many rival sites provide various e-wallet and alternative payment methods. We hope this is something 21.co.uk sportsbook will address in the future.

There is a £10 minimum deposit and a £5,000 maximum, while withdrawals are paid back to the same method used for deposits. 21.co.uk usually processes withdrawals within 48 hours, which is slightly longer than with some sites. However, the sportsbook says this is to prevent fraudulent activity. As a site aimed at the UK sports betting market, 21.co.uk only accepts GBP currency for deposits and withdrawals.

21.co.uk Global Betting Features

21.co.uk is a site that can provide a full range of betting markets with many betting features for customers to enjoy.

The most prominent of these is in-play betting, which features 10 sports. As betting has moved more and more mobile, people's demand for more fluid betting options has grown. With this sportsbook, you can place bets on sports such as cricket while the events are happening. You can place bets almost instantly to react to what you are seeing and place intelligent bets. Sports will have as many as 40 markets available in-play from which to choose.

The sportsbook also provides constantly-updating statistics for the live sporting event you are watching. It is said that knowledge is power, and 21.co.uk sportsbook gives you as much as possible before you place your wagers.

If you're looking for even more information to make informed bets, 21.co.uk sportsbook has you covered. There is a betting blog that offers helpful articles on a variety of sports betting markets and options. This tool gives players who like to think about their bets before placing them plenty of options before events start.

It seems likely that the number of features offered will change over time, so it is always a good idea to check out the 21.co.uk site to find out about new betting tools and features. Use any of the links in this review.

21.co.uk Sports and Markets

21.co.uk offers betting markets across an impressive range of sports, including these options:


As expected from a British bookmaker, soccer betting (or football, as it is called on the 21.co.uk website), this sportsbook provides extensive soccer coverage across all the major competitions and many smaller leagues. In some high profile events, such as the English Premier League and Champions League, you may find more than 100 markets.

The Live Betting section for football is comprehensive, including valuable in-play stats to help inform your betting. More soccer leagues covered by 21.co.uk sportsbook include Spain's La Liga, Germany's Bundesliga, Italy's Serie A, South American and even Middle Eastern soccer leagues.

American Football

The NFL betting is a huge market and is well covered on this site. There are over 200 markets available for a typical NFL game, and betting is also available on college football and the Canadian Football League in Canada.


21.co.uk provides extensive basketball coverage, which offers markets on all NBA matches and futures bets. It also has an impressive array of basketball tournaments worldwide, including leagues in Sweden, Denmark, Russia, Poland and China.


Tennis betting has grown in popularity over the last few years and forms a significant part of 21.co.uk's live betting platform. Tennis fans can bet pre-tournament or in-play, and markets like Next Point and Set Winner are available. We would like to see 21.co.uk expand its range to feature some live streaming to support in-play fans.


21.co.uk sportsbook offers excellent cricket coverage, from International Test Matches to the latest T20 tournaments. It is possible to bet on all the significant events, and we found the best odds offered to cricket betting fans were competitive compared with other sportsbooks.


European betting platforms are not always proficient at covering baseball, but we are pleased to see that 21.co.uk takes the sport seriously. Its market depth is most impressive on the MLB betting front, but you can also find coverage of other baseball competitions, most notably the Japanese NPB League.

Ice Hockey

Ice hockey makes for an exciting betting experience and is very popular among in-play bettors. It is pleasing to see that 21.co.uk sportsbook has broad ice hockey coverage on its betting platform. Through the site, you will find markets on NHL betting and all of the major international leagues.


The 21.co.uk golf bettingsection is comprehensive and provides plenty of betting markets across all PGA and European Tour events. However, we would have liked more generous each-way betting terms offered. This is something that golf bettors expect, particularly during the Majors.

Horse Racing

One of the main attractions to UK punters to 21.co.uk are the excellent horse racing betting markets from both the UK and Ireland offered.

21.co.uk Customer Support

Good customer support can be an essential part of the appeal of a top betting site. We were pleased with the lengths that 21.co.uk sportsbook has taken to provide an effective customer support section here.

You can access all the support features through the blue Help button on the left-hand side of the page. You can also access the live chat facility with the handy icon in the bottom right of your screen. The help section will take you to the sportsbook's range of Frequently Asked Questions, and you can answer a lot of troubleshooting questions here.

The Live Chat service is available on a 24/7 basis, which we feel should be standard for the modern industry. There is also an email option if you prefer to contact the support team using that method.

The support team is friendly and helpful, and it was refreshing to access staff members without being forced to read another FAQ. There was no chatbot either, just a straight connection to a real person. Wait times can be frustrating at times, but the service more than makes up for this.

21.co.uk Casino Review

The 21.co.uk casino is easily accessible via the Casino tab at the top and the side of the sportsbook home page. There are over 400 slot titles, progressive jackpots and many variants of popular table games, including roulette and blackjack.

All of the various games are easy to find through the menus at the top of the page, and while we have come across sites with a broader range of games, the 21.co.uk casino section provides a solid all-around casino gaming experience.

21.co.uk Live Casino Show

Live casinos give players the chance to experience what it's like being on the casino game floor from wherever they choose to play. 21.co.uk's live casino lets players join game tables staffed by real dealers live while the game is streamed to your device in real time. Players can also interact with one another and the dealers with live chat functions.

21.co.uk lets players choose from various games, including roulette, blackjack, poker, baccarat, and live game shows. Take advantage of the real-time live streams by playing live casino games with 21.co.uk.

21.co.uk Poker

Online poker rooms and tournaments provide players with a competitive experience against real opponents from around the world. Online poker does away with the 'house' and focuses on player vs player action. There are prizes up for grabs for those who win too.

21.co.uk does not have any poker rooms available, but those who want the taste of playing can head to the live casino. There, table poker games such as Casino Hold'em are held against live dealers, and you could have great fun with the chance of winning real money.

21.co.uk Lottery

Lotteries have always drawn in players because the prospect of winning prizes that can change your life instantly is often too good to refuse. As betting has moved online, players can now bet on a spread of lotteries worldwide to chase these jackpots.

There are no lottery bets available at 21.co.uk as of yet. This could be an area the sportsbook provider expands to in the future.

21.co.uk Bingo

Bingo gives its players a chance to socialise with a lively community while playing simple gameplay for prizes. This unique appeal is why bingo rooms are full of players eager to have fun while playing.

21.co.uk does not offer any bingo to its players. In the future, players can hope for the company to open bingo rooms for them.

21.co.uk Responsible Gambling

21.co.uk sportsbook offers a Safer Gambling section, which you can find on the left-hand side of the home page. It provides details on the various gambling safety tools available through the site. These include Deposit Limits, Reality Check tools and Time Out features. These come alongside Parental Controls and Wagering and Loss Limit adjusters. These resources are pretty easy to access, and 21.co.uk encourages you to use them to practice safe gambling habits.

Licensed by the UK Gambling Commission (UKGC), the 21.co.uk website complies fully with all aspects of responsible gambling. Still, we feel that the operator could have perhaps been more proactive in giving more visibility to this aspect on the 21.co.uk website. But overall, 21.co.uk sportsbook appears to take responsible and safe gambling seriously and offers plenty of resources and help.

21.co.uk Global Directory

At the time of writing our 21.co.uk review, the sportsbook is only available in the UK. Licensed exclusively by the UKGC and having a UK domain, it clearly serves its aim, which is to cater to bettors across the UK. However, owner LeoVegas Group is known for expanding successful brands and introducing them into new jurisdictions. Given the group holds other international licenses such as an MGA (Malta Gaming Authority) license, we would not be surprised to see 21.co.uk sportsbook being introduced to other regions such as Australia, New Zealand and Norway at some point in the future.
