Promotions for Existing Users

21.co.uk offers a wide range of promotional offers, including free bets, best odds guarantees on horse racing for UK and Irish horses, price boosts, and more. As is common in the world of online sportsbooks, 21.co.uk tend to release these promotions and offers surrounding huge events.

At the time of writing, a new promotion is offering a wide range of refunds on lost bets. You can get a free bet worth up to £25 if you guess the correct score, the match-winner, or the first goalscorer in English Premier League and La Liga matches. 

Besides that, you will see similar offers on Champions League, NBA Basketball, Premier League Darts, and much more. The team at 21.co.uk definitely know how to keep passionate punters coming back for more.

Is 21.co.uk Safe?

21.co.uk guarantees complete security and safety for its users. A big part of our review process involves testing whether that claim is true or not. 

As always, we started by looking at their licence. 21.co.uk is fully licensed by the UK Gambling Commission (licence 39198). As one of the strictest licensing authorities in the world, this is great news for customers. This means that 21.co.uk is held to high security and fairness standards, and that there's an organisation responsible for ensuring it.

While we usually prefer bookmakers who hold multiple remote gambling licences, they definitely chose the right one to start with when it comes to building trust. Plus, 21.co.uk is owned by LeoVegas, which is world-famous for offering punters and players alike a safe, high-quality experience.

As far as responsible gambling goes, 21.co.uk give their users access to great tools like self-exclusion, self-imposed deposit limits, and access to agencies like Gamcare and Gamstop.

Banking - Simple & Effective

There are only 3 payment methods accepted at 21.co.uk so far, but luckily, they’re just the ones we needed to see. Punters can deposit and withdraw via VISA, MasterCard, and PayPal.

While there isn’t as much variety here as we may be used to, this has allowed 21.co.uk to really streamline their payment processes. All deposits are instant, and withdrawals take under 24 hours to hit your account.

As with all other bookies in the UK, you’ll need to complete their KYC procedure to be able to request withdrawals, but we found that 21.co.uk processed that extremely quickly. As far as limits and minimums go, things are pretty reasonable here too:

  • Deposit: £10
  • Withdrawal: £10
  • Withdrawal Limit: £5000 p/transaction

Deposit Options

  • MasterCard MasterCard
  • Paypal Paypal
  • Visa Visa

Withdrawal Options

  • MasterCard MasterCard
  • Paypal Paypal

The Betting Experience

21.co.uk offers punters an array of sports and events that we can only describe as “impressive”. Of course, they feature all the big football tournaments, but punters at 21.co.uk can bet on yachting, trotting, darts, and much more.

In terms of betting markets, we were pleasantly surprised here too. 21.co.uk managed to keep up with larger bookmakers like Paddy Power:

  21.co.uk Paddy Power
Euro 2020 499 – 644 450 - 619
NHL 144 - 201 34 - 58
Pakistan Super League 27 - 51 24 - 62
NRL 96 - 98 38 - 54


While the selection of sports and markets is fantastic at 21.co.uk, punters should be aware of certain limits that the bookmaker imposes on wagers and payouts.

The minimum you can wager on a single bet is £0.10, which is great for those budget-conscious punters out there. As with most bookmakers, maximum bet amount allowed depends on the sport.

Moreover, there are certain restrictions with payout limits, and this varies by sport too. Football has a generous maximum payout of £250,000. Meanwhile, novelty bets are limited to a modest £10,000.

Odds Comparison

Here’s where we get to the most important part of our 21.co.uk review: the odds prices.

We tested 21.co.uk’s odds against a number of different bookmakers, and we were pleasantly surprised every time. For the example below, we compared 21.co.uk to Paddy Power, one of the biggest names in Irish and British betting. Here’s what we found:

  21.co.uk Paddy Power
Turkey 7/1 (8.00) 7/1 (8.00)
Draw 14/5 (3.80) 11/4 (3.75)
Italy 13/25 (1.53) 1/2 (1.50)
Overround 104.18% 105.83%
The odds above are for display purposes only. These odds were accurate at the time of retrieval, and Sportsbetting24 makes no guarantees that these odds will remain available or unchanged at any future date.

While there isn’t a huge difference between the odds, 21.co.uk still manages to provide better value for money. Looking at the overround score (the number that shows us the bookmakers’ profit margins), it’s clear that 21.co.uk are the better choice.

21.co.uk Betting Apps

21.co.uk works perfectly on phones and tablets. It’s clear to see that the people behind the scenes put a lot of thought into the optimization. 

Every feature that’s available on desktop is available on their mobile site and their dedicated iOS and Android apps.

The apps are listed on the App Store and Play Store, so all punters need to do to download the 21.co.uk app is search for it and tap on “Install”.

As you can see in the screenshots above, the mobile interface is neat and organized, and navigation is as smooth as butter. In fact, we conducted most of our review testing on mobiles!

Live Betting - But no Streaming or Cash Out

21.co.uk’s in-play betting suite definitely has potential, but the lack of some key features makes it difficult for us to recommend this to more seasoned live bettors.

Unfortunately, there is no Cash Out feature at 21.co.uk, which puts a huge limitation on the live betting experience. Without the ability to react to the action and cash out your bets, live betting just doesn’t feel as exciting at 21.co.uk as it does at other bookmakers.

Speaking of reacting to the action, you’ll need a separate screen to do that on. 21.co.uk doesn’t feature live streaming. They have a basic match-tracker widget and scoreboard, but there’s no way to really follow the match from within 21.co.uk.

Luckily, though, the excellent selection of betting markets and the competitive odds prices aren’t just reserved for pre-match bets. Punters can enjoy both of these things when betting in-play, too.

If you happen to already be watching the match, then the variety and the odds prices are probably attractive enough that this will suit casual punters just fine. If cash out and streaming aren’t important features for you, then definitely give 21.co.uk’s live betting suite a try for yourself. Otherwise, we recommend looking at bookmakers like bet365 or Unibet.

No VIP Club

Unfortunately, 21.co.uk don't have a VIP Club. This could make it difficult for high rollers, though the vast majority of punters shouldn't be affected by this. Those looking for a well structured VIP Club should definitely take a look at Karamba's VIP programme. They definitely know how to make big spenders feel welcome there.

While we'd love to see some sort of user loyalty programme implemented, 21.co.uk still has all the essentials covered for your average punter.

Excellent Customer Service

Unlike many other similarly sized bookies, 21.co.uk clearly take customer support seriously.

For starters, you won’t have to wait for hours or days to get a response. 21.co.uk are available 24/7 via live chat. We never had to wait longer than a single minute to be connected to a live chat agent.

The agents were always quick to respond and did their best to answer our queries. Our experience with 21.co.uk’s live chat was excellent, and we definitely recommend reaching out to them.

Email support responded reasonably quickly, too. Each and every one of our test emails were responded to within 12 hours. Of course, live chat is always going to be faster than email, but 21.co.uk definitely respond to emails faster than most bookmakers.

21.co.uk Contact Details

Focused on the UK

Unfortunately for our readers in other parts of the world, 21.co.uk is only available in the UK.

This is excellent news for punters in the UK, though. 21.co.uk take amazing care of their punters, and sports like football, rugby, and cricket are always included when new promotions and bonuses pop up.
