The brand name comes from the card game blackjack and while they do operate an extensive, high-quality casino experience, there is also plenty of sports betting available.

There are a lot of features to look over in this 21.co.uk bookmaker review, including things like live in-play betting, promotions and other important aspects like bet value and sportsbook variety.

We take a look at the entire package to help punters get a clear idea of what they can expect to get out of signing up with 21.co.uk.

21.co.uk Betting markets and odds quality 8/10

Betting markets

Perhaps the first notable thing about the 21.co.uk sportsbook is that when you land on the home page you are immediately presented with a lot of betting options.

Listed on that main page are upcoming sports events and with horizontal menus, you can filter the view.

For example, you jump to see what the next Cricket bets are, or the latest Tennis, Golf or Football options are.

But a nice touch is that whatever sport you are looking at on that main landing page of the 21.co.uk sportsbook, you can filter the view by different bet types.

That means if you are looking at International Friendly Matches for 21.co.uk football betting, then you could see the Double Chance markets for all of the games listed, or all of the Draw No Bet.

We mention this because it is part of a good navigation system that is on the website. It helps to get around the website very well.

There are icon buttons across the top of the main section of the sportsbook, to allow for quick access to full sports.

So a click on the Football Icon will take you to the football listing page and from there, there is a side menu that can be accessed.

That will allow the user to move around different leagues and competitions.

The colour theme of the 21.co.uk website is set on a black background with white writing and the odds are presented in blue.

It’s actually a very well-designed website because there is a lot of space in between markets and menu listings so everything is easy to read.

Good navigation and website design, while important aspects in terms of user-friendliness are not everything that needs to be examined in this 21.co.uk bookmaker review.

A quick glance at the sportsbook itself, we saw a lot of variety coming into play. Everything that you would expect to find at a major online sportsbook is there at 21.co.uk.

There is horse racing betting available from the operator. There are options from the UK & Ireland and international horse racing options available.

The 21.co.uk sportsbook does also have other options in there such as eSports and non-sports betting markets like TV & Novelty and Politics.

Next, for this 21.co.uk review, we will examine more in-depth, their football betting.

There is excellent football betting coverage to be found at 21.co.uk.

A click through to the football section of their sportsbook will conveniently list the forthcoming matches by date.

Looking around for this 21.co.uk sportsbook review, we saw a lot of competitions from around the world that were available.

There was the usual abundance of options from the bigger European markets like the Premier League and German Bundesliga.

That was alongside other options like the Mali Premier Division and domestic leagues from Iceland and Sweden.

So the football section of the sportsbook really reaches far and wide, giving punters plenty of scope for betting options.

Again another good design aspect of the 21.co.uk sportsbook is that if, for example, you were looking at a round of World Cup Qualifying matches for the day, there is the option of filtering the view by bet type.

It is possible to see the Half Time markets for all of the available fixtures, or all of the Double Chance options. There are plenty of different bet types to filter by, which is a good tool to speed up betting.

For each match that is clicked on, there will be an indication over if being live in-play and alongside that, there is a number stating the number of betting options available for that particular match.

We commonly found well over 400 betting options for major fixtures that were listed in the 21.co.uk football betting section of their sportsbook.

Some of them reached above the 500 mark, so punters do have a lot of excellent bet variety to hand.

Looking at the types of bets that can be found in football betting at 21.co.uk, alongside the main markets like outrights and goalscorer options, there is plenty of variety beyond.

We saw unique markets such as Stoppage Time/Substitution, Team Advanced Stats for things like total ball possession and total offsides, to player specials like To Score & Get Booked.

Another positive aspect for their football betting markets was listed Match Combination bets. All in all, 21.co.uk looks to have knocked the football bet variety right out of the park.

That applies to both the in-play and pre-match betting opportunities that are there.

We will explore the live in-play football betting side of things a little later in this 21.co.uk bookmaker review.

To sum it up, football betting with the operator is very extensive and highly impressive.

21.co.uk Racing Review

Horse racing betting can be found at 21.co.uk, filling out an already excellent sportsbook that they have.

Racing is from the UK & Ireland as well as fixtures from further afield like Australia and the USA.

So there is full coverage there for racing and integrated into some of the racecards are great insights and information.

It’s not just the regular stats that you get of form, there is more information available for runners in a field.

Punters get to see the previous odds, ratings, brief information about a particular runner in the field and a proper listing of their last six-race history including date and SP.

Again we do have to give 21.co.uk a good shout about their design and layout. Once again it proved to be excellent in the horse racing section.

Right on the page for a race that we examined for this bookmaker review, there was easy access to other bet types for the race.

There was a Winning distance of listed horses and forecast options.

Those were listed in individual boxes right on the page and therefore were separate and clear to spot and look at.

21.co.uk eSports betting

The growth of eSports and eSports betting has been huge and there is excellent coverage of it at 21.co.uk.

One of the visible qualities of any online betting site is just how much variety that they can provide customers.

That’s not just in terms of markets available but the variety that is on offer as well. Plenty of both was visible at 21.co.uk.

With regards to different eSports games that were there for betting, we saw CS: GO, League of Legends and Call Of Duty.

The competitions were from all around the world, including the likes of France, Poland, the Netherlands, Asian leagues and some of the bigger US competitions.

There were good options for map betting, map handicap and match betting markets for some of the action, CS: GO being particularly well covered in that regard.

All in all, we saw an impressive range of eSports betting at 21.co.uk and some of that was offered with live in-play betting options as well.

21.co.uk Novelty Markets

There are those times when players may want to step away from actual sports betting and take a look at some betting options for current affairs, politics or entertainment.

For the next part of this 21.co.uk review, we are going to explore some of the non-sports betting markets that are available in the sportsbook.

Within the main sportsbook menu, there is a section for Politics and one for TV & Novelty to explore these types of bets.

These are not always areas within a sportsbook that you can find a lot going on, not outside of major events like General Elections.

But there was good coverage within the 21.co.uk Political menu, looking well ahead to future markets like Next Prime Minister and we saw Next Party Leader options.

One thing that we also noticed coverage in this Politics section, on what may be considered more obscure markets, was good.

Such as eleven different betting options available for the Next Norwegian Election, covering things like the percentage of Votes by party alongside the main outright market.

It was just another strong indication of how much variety the operator has thrown into their sportsbook.

For the TV & Entertainment section, there were TV show markets from around the globe, such as The Voice Australia, along with Awards sections like the Nobel Peace Prize and Time Person of the Year and BBC Sports Personality of the Year 2021.

21.co.uk Sportsbook Summary

There is a lot to be enjoyed at the 21.co.uk sportsbook. The navigation aspect of the sportsbook is excellent because it is clearly designed to make betting a quick and simple process.

The main sportsbook landing page is chock full of options, but if you do need to go digging around a little more in specific sections, it’s easy to get around.

There are clear navigation links everywhere and the pages for individual markets are very well laid out.

The sportsbook makes access to live in-play betting opportunities easy as well and there is also a search bar where you can quickly search for something specific that you want.

After making any selection the bet slip will pop up in the bottom right of the screen, listing all of your options there. Multiples can be managed directly at the betting slip as well.

Odds Comparison

odds comparisons

Just for one final aspect of the Sportsbook, we wanted to look at a quick example of bookmaker margins that are at 21.co.uk.

For that, we looked at a couple of football matches. An international fixture between Turkey and Italy had an amazingly low margin of 2.56% on the match outright.

Another fixture between Russia and Belgium was running at a 4.58% margin on the outright.

The more obscure the match, the bigger the margin is likely to be, which is as expected as fewer punters are going to be playing it.

But those football margins that we looked at, did appear to be strong and competitive for online betting.

21.co.uk In-play betting 8/10

in play betting

The modern-day approach to betting, being able to get wagers done on the go, is a hugely important factor.

Just having wagers available at your fingertips, either throughout a desktop or through a mobile betting app, opens up a lot of extra opportunities.

Add in the ability to watch live streams of sports events alongside in-play betting then it’s a dynamic and exciting way to wager.

So for the next part of this 21.co.uk sports betting review, we are going to cast an eye over the in-play betting opportunities that the operator has.

Just a click to their sports betting page will present a lot of in-play opportunities.

All of the excellent navigation and filtering of bet types are available for live in-play betting.

On top of that, it is easy to see just how extensive their in-play betting options are from that home page.

But for the purpose of this sportsbook review, we are going to look at some of the big in-play areas to explore more features.

21.co.uk In-Play Football

Depending on the time remaining in a football match and the magnitude of importance on a game, there will naturally be fluctuations in how many betting options are open for a live in-play football game.

We dived into some international football action to take a look at the 21.co.uk in-play football betting in a little more depth.

There was an average of around 30 wagers available on in-play games, while a bigger fixture between France and Bulgaria had more than 90 available at the start of the second half.

Click on an individual fixture for live in-play betting and there is a well-organised page of options.

There is a selection for selected markets such as the Full-Time options and Over/Under Total Goals.

One feature that we saw in there, was a menu link for a live Bet Builder to be created.

A click on there will show the qualifying markets, such as Full Time, Total Goals, Both Teams To Score, Correct Score, Total Goals By Team and so on that are available.

There is a lot of superb bet variety. On the main page for an individual game, there are stats displayed.

There’s a little graphical representation indicating statistics as they happen, such as the number of attacks, number of shots on target and the number of dangerous attacks each team has had.

An alternative action view can be taken, which notifies what is currently happening in the game, such as Team A attacking, or Team B Free Kick and in which area of the pitch things are happening in.

A separate Events box was available on the match we examined for this 21.co.uk review.

That presented the option for Next Corner, No Corner No Bet and there was a list of times that corner had happened in the fixture.

21.co.uk In-Play Tennis

The same in-depth coverage that is there on the in-play football was also available on a live tennis match that we looked at.

For this review, we looked at the Grand Slam match from the French Open. There were selected markets such as the match outfits and set winners.

There were also good totals options like the number of tiebreak points in a given set.

Another good aspect of in-play tennis betting on the website was instant betting, which could be found across the top menu for the given match.

This offered rapid-fire markets on who would win the next point in the fixture.

The match was further broken down to score in a given set and a tie-break correct score in a given set.

On top of that, there was an excellent breakdown of statistics for every game that was played within the match, allowing punters to see how the flow of points had gone.

21.co.uk In-Play Summary

All in all, there is a superb in-play service that is operational at 21.co.uk. So you can cast a wide net over a lot of different sports and competitions.

We saw Basketball, Pool, Volleyball, Football, Tennis and so much more when visited for this 21.co.uk review.

Extras & features of 21.co.uk 8/10

Extras & features

For the next part of this review we are going to look over some of the key extras and features that are available at 21.co.uk.

Features are things that we consider enhance the experience that can be taken.

Options that allow punters to take some extra control of their betting are the kind of thing that we are looking for.

Cash Out

There is a cash out feature available at 21.co.uk which is offered on specified single bets.

That means that a wager can be settled before the completion of the event at reduced odds.

The odds and cash out value will fluctuate throughout the duration of the given event, depending on the situation of what’s happening.

Click through to your account and select “Open Bets” and then choose your selected bet and select the “cash out” option for it.

Bet Builder

There are Bet Builder options available at 21.co.uk as well and they can be found pre-match and in-play.

If you see the option available through a menu link for a fixture, then it will raise the markets that you can select to build the wager.

A Bet Builder is where you select options for a game to create a specific bet of your own creation, from pre-set markets.


There are Virtuals at 21.co.uk which can be accessed through the Virtual Sports Lobby. Virtual Sports betting offers a simplified and quick betting platform.

They are just randomly generated games in terms of results that happen.

You place a wager on what you think the outcome of a football match, a horse race or a F1 race will be.

They are games, more on the casino side of things than actual sports betting.

Virtuals offer computer generated sports running 24 hours a day with a quick turnover in matches.

For a virtual football betting, a punter would select from very limited markets, usually just the outcome of the match, total goals, double chance, First team to score, correct score and HT/FT.

Again, as with any Virtual betting, you are going to be more limited with market options compared to real-world action.

It’s important to remember that the results are randomly computer generated.

Other versions of Virtual sports include greyhounds, basketball and American football.

21.co.uk payment options - deposit and withdrawal methods 7/10

payment options

The main deposit methods that are available to fund an account at 21.co.uk are Visa, Visa Debit, Visa Electron and Mastercard along with Paypal.

The minimum amount you can deposit is £10 and that applies to whatever deposit method that you are using for the account.

On the other side of that, the minimum that can be withdrawn from the cash balance at 21.co.uk is £10 also.

How to do a 21.co.uk withdrawal

To make a withdrawal at 21.co.uk you have to visit the Banking section after clicking on your profile icon.

From there you can select the Withdrawal option and follow the steps to complete a transaction.

For 21.co.uk to safely complete the transaction, you may need to verify your account before your first withdrawal.

If that’s needed then the operator will send you an email with all the details to do that. It’s common practice with online bookmakers.

Withdrawals will vary in the time that they take to reach you. Even after 21.co.uk has sent the money out, there is potentially a delay in your financial institution processing the transaction.

It can take up to 5 working days until you get the funds, depending on the method in question. Again if your account is already verified, this will not cause a further delay.

User-friendliness of the 21.co.uk website 7/10

User-friendliness of website

Even though the website runs off a dark theme, with a black background, everything looks artistically appealing at 21.co.uk.

What we really like about the design is the separation of things into boxes when it comes to looking at individual events.

That gives a clear separation between different types of bets, and things like statistics, which are done very well on the site.

The navigation all-around is excellent.

There’s so much available right on the main homepage of the 21.co.uk sportsbook that there’s not a lot of need to go browsing around.

Even for this review, we looked around at different sports and rarely did we even raise the main sportsbook menu.

That’s a testament to how well navigation is done, through menus and the sorting of betting events through dates, which we enjoyed a lot.

We felt that added a lot of user-friendliness for punters, both on pre-match events and live in-play betting.

The bet slip was unobtrusive, the website did not respond slowly in any aspect, and overall, it just looks very good.

21.co.uk Mobile App review 6/10

mobile app

There is not a dedicated 21.co.uk app for sports betting. There is a Casino app available for iOS and Android.

The 21.co.uk sportsbook can still be accessed through a mobile web browser to get the full experience.

We found that it was just as quick to operate and easy to navigate as the main desktop full website was.

All of the features like integrated stats for live in-play betting were readily available there.

21.co.uk Customer Service & Support, Security & Reliability 7/10

21.co.uk Customer Service

The quickest way to get any support on the 21.co.uk website is to click on their Help menu option.

This is always sat at the top of the page, it’s easy to access to get to that.

Directly on that Help Centre page is the option to launch a 21.co.uk live chat so you can get access to customer support through there.

Also available is an FAQ help section that is broken down into different areas.

Each of the sections, such as Account, or Deposit & Withdrawal have FAQs inside, which should be able to help you along.

It is also possible to leave 21.co.uk a message through a form in their Help Centre. There is no direct support telephone number to contact the operator through.

21.co.uk are licensed and regulated in Great Britain by the Gambling Commission and they are aligned with organizations like BeGambleAware.org to help customers with gambling issues.

As for security on the site, it’s all SSL encrypted for safe and secure payments.

Our 21.CO.UK REVIEW 2024 - BOOKMAKER RATING & SIGN UP BONUS review rating: 7 / 10

So we come to the conclusion of this 21.co.uk bookmaker review.

They are a big player in the casino industry, but they have a tremendous amount to offer in sports betting as well.

There was a lot that we enjoyed in their sportsbook and right off the top the number of betting markets and variety of bets was just highly impressive.

Whichever sport we looked at we were impressed by the number of pre-match and in-play bets that were available.

The website is really easy to get around as well, there has been a lot put into the navigation there. So we found it quick and easy to find different bets within different sports.

Most of it, very conveniently, was driven from the main home page. There are not a lot of features around the website, no live streams for example, but what is there is very good.

Again, we can’t stress enough how highly we liked their sportsbook. It’s strong, packed with options and fully functionable.

All in all, 21.co.uk looks as if they could be a good addition to any online bettor’s options.
