21.co.uk Review (2023)

21.co.uk has definitely made a big impact in a short space of time since it was launched in 2019.

There are dozens of new online casinos launched in the UK every year. Most don’t really make a big impact, but occasionally a new online casino and/or sportsbook comes along that is something a little bit different.

The site is super user-friendly, has an eye-catching design, and has some innovative features to keep players interested.

For instance, 21.co.uk casino has its own live TV show that broadcasts daily on Channel 5 in the UK.

So, let’s dig a little bit deeper into 21.co.uk casino and sportsbook and find out why we think it is one of the most exciting and rewarding new online casino and betting sites out there at the moment.

A Brief History of 21.co.uk Casino & Sportsbook

Originally owned by Intellectual Property & Software Ltd, but bought out by LeoVegas Gaming PLC, 21.co.uk was launched as an online casino and sports betting site in the UK in late 2019. LeoVegas is one of the biggest online gambling providers in the world and is licensed in pretty much all of the countries where online gambling is legal and regulated. LeoVegas owns other online casino brands such as LeoVegas, BetUK, and Royal Panda.

21.co.uk made an immediate impact due to its striking design and attention-grabbing branding. They also offer a generous welcome bonus, an easy-to-use site and mobile app, and a fun, innovative user experience. For these reasons, they have already become a popular gambling site and are set to grow even more in the coming years.

21.co.uk is fully licensed to operate in the UK by the Gambling Commission (UKGC), which means you will get a safe, fair, and secure gambling experience. 

21.co.uk Sportsbook Review

21.co.uk no longer operates its sportsbook in the UK. But, the live casino and casino games are still available.

Promotions for Existing Customers

As well as the welcome bonus for new players outlined above, 21.co.uk also offers a range of promotions and special offers for existing players.

Regular promotions and offers include:

  • Free bet promotions
  • Best odds guaranteed
  • Price boosts (enhanced odds)
  • Money-back on losses
  • Event-specific promotions.

It is relatively unusual for such a new online sportsbook to offer so many promotions and rewards, as they are usually more focused on attracting customers initially. 21.co.uk is different, as they are keen to both attract and retain players by showering them with valuable offers and deals as they grow their brand, which is good news for players!

Range of Sports

Although 21.co.uk is a new sports betting site, they have a pretty impressive range of sports and betting markets available. All the major sports are covered including football, rugby, cricket, tennis, golf, formula one, horse racing, snooker, darts, boxing etc. But they also offer some more unusual or niche markets such as yachting, volleyball, politics, eSports and virtual sports.

Betting Markets & Odds

The betting markets that 21.co.uk offers are large and compare favourably with bigger online bookmakers such as Paddy Power and Betfred. The odds on offer are also highly competitive with low margins. We compared football odds with Paddy Power and 21.co.uk scored better with slightly higher odds on most match results. 

To help you decide what to bet on and hopefully be a winner, 21.co.uk offers a betting tips service that has industry experts sharing their advice.

Live Betting In-play

21.co.uk has a  nicely designed and intuitive betting interface that is well suited to live in-play betting. You can place bets very quickly so you don’t miss out on any of the action.

However, there is no cash-out feature, which detracts from the in-play betting experience somewhat. Also, there is no live streaming on offer at 21.co.uk.

Compared to other online sports betting sites, 21.co.uk needs to improve its live betting experience, which is passable at the moment, but not great.

Mobile App

As a new online sportsbook, 21.co.uk is making sure that they have as many attractive features as possible, which is why they launched mobile betting apps for Android and iOS alongside their website. This means that punters can simply download the app from the Google Play Store or Apple Appstore and play on their mobile devices.

The mobile app works well, looks great, and is fully optimised to give you a speedy and satisfying betting experience on your phone or tablet.

Customer Support 

New sportsbook sites often let themselves down a bit when it comes to customer support, as they don’t always have the budget to provide a 24/7 service. However, 21.co.uk offers top-tier customer support with 24/7 live chat and email support, both with rapid response times.

Summary of 21.co.uk Online Sportsbook


  • Excellent, easy-to-use software and design
  • Highly competitive odds and plenty of markets
  • Mobile sports betting apps for Android and iOS
  • Top-tier customer support - 24/7 with fast response times


  • No cash out during in-play betting
  • No live streaming
  • No loyalty rewards program

Many of the slots games have progressive jackpots attached to the site’s “Jackpot King” feature, with many worth £10,0000’s, such as Gold Frenzy and The Goonies.

Payout Percentages

Also known as the Return to Player (RTP) percentage, this refers to the percentage amount that players win back each time they place a bet. For instance, a slots game with an RTP of 99% means that you will get back a total of £0.99 for every £1.00 you spend.
