Is 21.co.uk Sports Safe?

If you’re looking for a safe betting platform with a large variety of sports, then 21.co.uk could be what you need.

This established brand is renowned for its great mobile experience. In our 21.co.uk Sports review, we’ll put this to the test.

We’ll also and take an in-depth look at the bonuses, customer support and more. Read on to discover all you need to know.

In terms of security, we take a forensic look through the sites claims to ensure that players will be protected. For our 21.co.uk review, we compared its security features with LeoVegas and were pleased to see these were matched.

21.co.uk makes use of the highest quality encryption assets, 256-bit SSL. This ensures that your sensitive data is well protected so you can feel safe sharing your details. Many of the best betting sites use only 128-SSL encryptions which are solid enough, but 256-bit is the top of the range.

Furthermore, we discovered strong firewalls in place which enhances the security level.

Protection of Funds

Simply because LeoVegas Gaming plc is the parent company to 21.co.uk also gives it a few extra safety points. In saying that, there is one area in which both are slightly behind. That is with the protection of funds level. For 21.co.uk this is set at: not protected.

While that might seem alarming it’s worth remembering that this only comes into play in the unlikely situation that the company is forced into administration. At a not protected level players are not guaranteed to receive the monies in their account.

In general, we see most betting sites with a medium rating. But, as mentioned it’s not a deal-breaker, it’s just good to know.

Key insights: While the rating for protection of player funds is low, it’s a highly unlikely situation for this to be required.


As the name might suggest, 21.co.uk is aimed at a UK audience. It’s, therefore, no surprise that they are licenced by the United Kingdom Gambling Commission (UKGC). The licence is held by LeoVegas so it is fully responsible for the brand.

The UKGC are well-known to be strict with their rules and have handed out millions of pounds worth of fines. 21.co.uk has been in operation since 2013 and has never found itself in trouble with the authority which is great to see.

Some betting sites hold multiple licences across several territories, but as 21.co.uk is solely focussed on UK users this isn’t necessary, and we won’t mark them down for it. Furthermore, if LeoVegas wanted to extend the licence with this brand, they would likely be able to do so.

Key insights: LeoVegas is licensed by a further six authorities and are highly trusted.

Responsible Gambling

There is a ‘safer gambling’ tab within the main menu on-site showing that 21.co.uk have this at the forefront. Much like LeoVegas, it provides its players with a wide range of tools. These are:

All of these topics are explored on the page accompanied by genuine advice. We think it is one of the best offerings we have seen as it goes beyond its licence requirements.

Furthermore, there is also a mention of ‘LeoCare’. This is an initiative set up by the company to provide not only advice but support in the form of paying for therapy sessions. This is not something we’ve come across elsewhere and is hugely positive to see.

Key insights: It’s always worth checking out what tools are available as some can be useful for casual players too.

21.co.uk Can Be Trusted Because
  • Part of reputable group
  • Takes responsible gambling seriously
  • Uses SSL encryptions to protect your data
  • Licensed by the UKGC
  • Provides excellent, 24/7 customer support

In this case, it’s a basic bet £10 and get £10. The £10 free bet must be played in-play which about the trickiest term there is.

Once your free bet is awarded; you’ll need to tick the checkbox within the betslip. Don’t forget this step as otherwise, you’ll be using your own funds.

Offers for Existing Players

At the time of writing, there are no dedicated sports promotions within the tab on site.

We contacted support who confirmed this was there was additional sports offer running at the time, but that other offers will likely commence shortly.

We also noticed that at the bottom of the promotions tab 21.co.uk suggest that offers may be sent via marketing communications. Therefore, we recommend that you opt-in for those to avoid missing out.

Key insights: Opt-in for marketing communications that suit you. If you don’t want to receive an SMS for example, tick email only.

21.co.uk is targeted at a UK player base so you’ll find a wide range of top sports to bet on such as:

On top of those main sports, you can extend to their full list which is more than 30. This means you can also bet on:

This is not an exhaustive list of the sports on offer, but we’re highly impressed with the options available.

To give a full look at the sportsbook for our 21.co.uk sports review, we also have to consider the market depth. It’s all well promoting all those sports, but are there markets to bet on? The good news is that there is, yes. We found that football markets were especially deep with plenty of options for goalscorers, number of corners, etc.

We would note that a bet builder function is missing which is disappointing. It is a feature that many bookies in the UK promote so it is something we think could be added

Maximum Payouts

Maximum Payouts at 21.co.uk Sports
21 sports review maximum payouts by sport
Top level football
Grand slam tennis final rounds
Other football
Major golf events
UK and Irish Group 1 horse racing
Other horse racing
Snooker top events

All betting sites set maximum possible winnings, and they are usually different depending on the sport. Some sites are not as open about what these limits are so we like how well detailed 21.co.uk are in this department.

The limits themselves are also very reasonable. The best betting sites provide high limits on football and horse racing. William Hill and bet365 lead the way with huge limits of up to £2,000,000 for premium events, but very few bookmakers come close to this.

Key insights: Bear in mind that limits on these apply to accumulator bets, so check the maximum payout before you place your bet.

Horse Racing at 21.co.uk Sports


The horse racing offering at 21.co.uk is excellent. You’ll find fixed odds on all UK and Irish meetings every day with specials also online. Antepost betting is possible too and easy to access.

On top of UK tracks, they also provide fixed odds on select international tracks. During testing, we came across these in Australia. Not all bookmakers provide this to players, so it stands out.

Best Odds Guaranteed

Furthermore, a support agent also confirmed that best odds guaranteed is offered on all UK and Irish racing. This is great to see for a relatively small bookmaker as it’s not something that all provide.

This improves the horse racing offering considerably, as it is excellent for players.

If you’re not sure what it is, best odds guaranteed (BOG), means that if you back a horse to win at 2/1 but the horse starts the race at 3/1 and wins, you will be paid at the higher odds. 

The additional winnings are also paid in cash, so there’s no wagering either.

Key insights: Best odds guaranteed only applies to fixed odds bets on UK and Irish races, and your account needs to be eligible for bonuses.

21.co.uk Competitive Odds

Getting value with your betting odds should be high on the list for most players. By value, we mean that the odds are competitive with the rest of the market.

Let’s take an example of a EURO 2020 match between Portugal and France:

Portugal vs France Margins
BookmakerNumber of Markets1×2 Margin
William Hill642+105%

As you can see, 21.co.uk are certainly offering good prices. Every bookmaker builds a margin and usually sits somewhere around the 2% per outcome range. In this case, Portugal win, draw, or France win. Therefore, we can say that 21.co.uk are providing very generous odds at a little over 1.3% per runner.

It’s worth bearing in mind that that this is one market only. So, for our 21.co.uk review, we had a look into the popular over/under goals market. We can see that they are in line with the industry here too, so you can be sure that you’re getting a good price.

Key insights: If you’re not sure if you’re getting good odds or not, a quick comparison for the market you’re looking at with a couple of other betting sites should let you know.


It’s important to know what platform you are playing on. This might seem a little strange but betting sites are often hosted by a third party. 888Sport are the exception here as they have built everything in house, but that is extremely rare.

21.co.uk use Kambi sports for their sports betting site. Kambi is very well respected and also have relationships with William Hill, LeoVegas and Unibet to name a few. They hold an excellent reputation, so we’re pleased to see that they are the providers.

It’s worth noting that Kambi can also provide odds from their own traders. However, 21.co.uk use their own traders meaning that odds are unique to them.

In-Play Betting at 21.co.uk

To access the live betting options at 21.co.uk you need to head to the sports betting tab on the menu, and then select the ‘live right now’ banner. This also displays how many events you are currently able to bet on in-play.

When you reach this section of the site you will clearly see the sport, event and number of betting markets. It’s a nice set-up and there is also the option to see what is upcoming, which we like.

Odds change quickly and in testing, we didn’t come across any glitches. These can happen sometimes in live betting as with sports such as tennis the odds can change very quickly.

Overall, we like the in-play section and it is fairly standard in comparison with others.

Live Streaming

The major downfall with this betting site is that live streaming is not available on any sport, including horse racing. This is disappointing as they excel in the in-play markets.

In saying that, they are far from the only site to not offer this service. It can be very expensive to operate with streams costing well into the thousands of pounds.

Instead of streams, they offer some live-action animations that are nice but don’t quite make up for the lack of streaming.

Cash out at 21.co.uk Sports

We’re pleased to say that 21.co.uk have recently introduced a cash out feature on-site. It is only available on limited markets, but the vast majority of top football games are in this.

As part of our process, we tried the feature out and found that it was easy to use and works in the way that players have come to expect. The payout amounts that we were offered were in line with LeoVegas who we tested on the same market, so it all looked good.

The only downside is that neither auto cash out nor partial cash out are available. It’s straight cash out all of your bet, or leave it all. Many bettings allow you to cash out a part of your stake, so it’s disappointing not to have this option.

It provides an extra element to live betting, and although most online bookmakers now offer it, not all do so it’s great to see.

Key insights: Cash out should be used wisely as it often doesn’t offer much value to players.

Payment Methods

21.co.uk Sports Minimum Deposit and Withdrawal Times
Payment MethodMin Deposit/WithdrawalWithdrawal Time
Visa£10/£103-5 working days
Mastercard£10/£103-5 working days
PayPal£10/£10Within 24 hours

Players can deposit at 21.co.uk via only a limited number of options. At the time of writing only debit cards or PayPal are accepted.

While this is considerably fewer than other sites offer, we do rate PayPal highly so it’s not terrible. Furthermore, deposits by PayPal are eligible to claim the welcome bonus. This is not always the case with other betting sites.

Withdrawal times are standard for the industry. Debit card withdrawals can sometimes be instant with bookies such as Paddy Power but around 3-5 working days is the average.

Some betting sites also state that PayPal withdrawals can take up to 48 hours to process, so within 24 hours at 21.co.uk is great.

As you might expect with 21.co.uk being part of the LeoVegas Group, it provides an excellent mobile app to its players.

It can be downloaded for free on most devices, both Apple and Android and provides great usability.

In terms of safety, players can set up Touch ID to access their account or even use Face ID, depending on the device. This adds an extra element of security and it’s something that we highly recommend you do,

The app is quite large, so for players conscious of that, you’ll be pleased to hear that the mobile web version is every bit as good, and secure. The pages automatically adjust as per your device and the hamburger menu stores everything in a tidy manner.

We rate the 21.co.uk app as one of the best betting apps in the business and players who enjoy betting on the go will not be disappointed.

Extensive collection

When we see a 24/7 live chat is available, we always get the feeling that the site will be legit. It takes a good amount of commitment for a company to offer around the clock support in such a way. Of course, they probably do use the same agents as LeoVegas so this is an advantage for them.

We found the response time to a little slower than some betting sites we’ve contacted, but we were connected in around 1 minute.

You can expect to wait up to 48 hours for a reply to emails, which is the average waiting time for betting sites replying in this channel.

The FAQs were very helpful. Our only complaint is that the sports and casino sections were mixed up here, but we were able to navigate to where we wanted to be.

Key insights: Live chat is available when both logged in and out, meaning you don’t have to register if you have a query first.


Having tested 21.co.uk we can say that we’ve enjoyed the overall experience. The colours are clear, and there are no annoying pop-ups or unnecessary graphics on the screen.

The main menu bar is clearly tagged, and the site layout was logical, in our opinion.

21.co.uk is better known as an online casino so you will come across casino content too. This is mixed together with sports in the promotions tab, which can get a little confusing at first glance.

The 21.co.uk casino comes highly rated too with over 500 games, including 70 jackpot slots and over 150 live casino tables. If you enjoy a multi-purpose betting site, then 21.co.uk delivers.

Tips and Tricks

Top 5 Tips

  1. Deposit with PayPal to claim the welcome offer
  2. Make sure your first bet meets the qualifying conditions for the bonus
  3. Download the app for the best experience
  4. Try the cash out feature
  5. Opt-in to marketing communications

Improvement Areas

The welcome bonus is reasonable, but it is less competitive than others out there. A £10 in-play free bet is great, but some sites such as William Hill offer £30 in free bets for a £10 deposit.

We’d like to see some more payment options available to players too. Having PayPal there is a big plus, but we were surprised to see such a limited number of options, especially considering LeoVegas offer more than this.

Furthermore, the withdrawal times are average at best. Some sites provide such as Paddy Power offer instant withdrawals to e-wallets and debit cards.

The lack of live streaming is also something we’d like to see improve. 21.co.uk provides an excellent betting experience, but live streaming is highly valued for sports such as horse racing. It’s something we’d like to see added.


In this 21.co.uk sports review, we’ve shown why they can be trusted, and why they are rated highly on legit.org.

They provide an excellent betting platform with strong security features, competitive odds over many markets, and have extras such as cash out.

21.co.uk would be the perfect choice for the casual player with its easy to use interface and top customer support. It’s one that we definitely recommend.
