Sports Betting Bonus Guide 2021

Check the list above for top sports betting bonuses for British punters.

Online sportsbooks are not shy to lure you in with lucrative bonuses. They have money to spend, and if you’re smart, you can get extra money to bet with. On top of your sports betting bonus, you’ll also receive free slot spins, casino bonuses and whatever else the gambling site can think of.

Here’s the three most common type of sports betting bonuses available at UK bookies:

  • Deposit deals
    Deposit to receive more money to bet with. For example: deposit £50 to receive £50 bonus and bet with £100.
  • Risk-free bet
    Make a bet. If you win, you keep what you won. If you lose, the betting site pays you back.
  • Free bet
    The sportsbook provides you with free money to have a nibble with. Most often you get to make a £10 – £20 free bet after making your first real-money bet.

Deposit Bonuses

Deposit bonuses match your deposit with bonus money you can punt with. These promotions hand you more money than any other kinds of promotions.

When you sign up to a betting site, customers are sometimes offered a chance to get a deposit bonus. Deposit bonuses consist of the maximum amount of extra cash you can get and a match-up percentage.

Let’s interpret a typical bonus at a UK betting site like 100% bonus up to £50.

  • The first number (100%) is the match-up percentage. In this case, if you deposited £50, the betting site would calculate your bonus like this: £50 * 100% = £50.
  • The second number (£50) shows you that the maximum you can receive is £50. If you deposit a sum that would result in a bonus bigger than £50, the rest is ignored and you’ll receive £50.

Like to bet on hockey? You can use your bonus to punt on NHL and every hockey league on the planet.

How to Get Your Bonus

  1. Choose one of the sites listed above
  2. Register at the site
  3. Deposit at the cashier
  4. Use a bonus code if required*
  5. Choose to accept a bonus**
  6. Start playing

* Bonus code or promo code is not required at most sports betting sites. If one is required, it’s listed above in the table.
** Some sites require that you choose to accept a bonus. If this is the case, there’s a box you need to tick at the deposit screen.

Clearing a betting bonus

Before you can withdraw your winnings, you need to meet a rollover requirement. Every deposit-based sports betting bonus comes with a rollover requirement. The rollover requirement is usually stated somewhere in the terms & conditions. This number tells you how many times you need to bet your money before you can cash it out.

For betting, the rollover requirement is usually 3 to 5. Compare this 3-5 to casino bonuses, which have a rollover requirement of 30 to 50!

Bonus clearing example:
You deposit £50 and receive £50 with a rollover requirement of 3
You need to bet: 3 * (£50 + £50) = £300

You need to play with certain odds for your bet to count towards clearing your bonus. This limit is often 1/2. Bets below the limit are ignored as far as clearing the bonus goes.

Risk-Free Bets

When you place a no-risk bet you either win or get your money back, if the bet loses.

Risk-free bets (often incorrectly called “free bets,” which are explained below) are common betting bonuses. If your bet loses, you get your money back. If you win, you keep your winnings. Gamblers love them, so UK sports betting sites are more than happy to offer them to customers.

Deposit bonuses are usually only available for new customers, but risk-free bets are also offered for existing customers. These kinds of loyalty promotions are common, especially during big sporting events. Big events include the likes Cheltenham, Royal Ascot, big football events (World Cup, Champions League Finals) and the Rugby World Cup.

A typical risk-free bet has these restrictions:

  • Stakes limited to £10 – £50
  • Bet only available for a specific match
  • Bet only available for some markets
  • Minimum odds apply (usually 1/5 or higher)
  • Maximum win is limited (usually £10,000)

Here’s what happens after placing your bet:

  • If you win with your no-risk bet, great. You keep your winnings.
  • If you lose with your no-risk bet, the site refunds your stake.
  • If you lost, you may need to contact customer support to receive your refund.

An important thing about losing:
Depending on the internet sportsbook you play at, you may need to contact customer support to receive your refund. Not all betting sites in the UK, or elsewhere, do these refunds automatically. If the return is automatic or not, is always mentioned in the promotion so make sure to read it. Plenty of gamblers forget to claim their funds!

When you do get money back, it’s usually in the form of a “betting token.” With the token, you can bet again, but you can’t cash it out immediately.

Free Bets UK

Free bets are the simplest betting promotion: the sportsbook hands you a lump sum of money (most often £10 or £20), and you bet it.

Calling these free bets is slightly misleading. They’re reserved for customers who’ve shown they’re willing to put their money on the line. If you don’t want to deposit any money, then you should check out for example our UK Starburst no deposit free spins page. There we list no deposit free spins offers to one of the most popular slot game out there – Starburst. Other interesting section is the free spins on card registration UK 2021 page. There we list casinos where you will get free spins with registering your debit card. Another option is just to claim up to 50 no deposit free spins from Cashmo.

Terms and Conditions

Free bets have simple terms and conditions. As long as you don’t split the bet and don’t exceed the time limit, there’s nothing of consequence to know. It’s still good to understand the free bet terms and conditions.

  • No Splitting:
    You can’t split free bets. If you receive, for example, £20 then you need to bet £20 on a single market.
  • Minimum odds:
    There’s usually 1/2 (1.5 in decimal odds) minimum odds you have to meet
  • Maximum win:
    The maximum tends to be in the tens of thousands, so it’s not something to worry about.
  • Time limit:
    Free bets have strict time limits. Usually, you only have seven days to use a free bet token you’ve received.

Can I Use Bookies’ Free Bets in an Acca?

It depends on the bookie. Most times, however, you can use your free bet in an accumulator. At Mr Green, for example, you can use your free bet in an acca.

UK: Best Betting Sites

Best Mobile Betting Site Leo Vegas
Best In-Play Betting Site Leo Vegas
Best eSports Betting Site Betway
Best UFC Betting Site Mr Green
Best Premier League Betting Site Rizk
Best NHL/NFL/NBA/MLB Betting Site 888 Sports
Best New Betting Site 2021 LeoVegas & Rizk

You’ll find all the best UK betting sites from the list above. Below you’ll find the detailed description of best bookies for different sports.

Best Site for Mobile Betting: LeoVegas

LeoVegas is the best sportsbook for UK mobile punters. It’s an instant play sportsbook (no download needed), fast, and easy to navigate. Just get the LeoVegas sports bonus and you’re set.

You can play at LeoVegas with your tablet or smart phone. The LeoVegas sportsbook works smoothly on iOS, Android and Windows Phone or tablet. Leo Vegas has one of the best overall sportsbooks in the market. They’ve got very competitive odds, their selection of sports is right up there with the best of them, and they cover all UK payment methods.

Best Site for In-play / Live-betting: LeoVegas

LeoVegas’ sports section is the best option for in-play betting if you’re betting on the go. It is fast, responsive on mobile and you’ll get your bets in in no time. William Hill is of course in the race as well.

You can bet plenty of sports live, such as:

  • Premier League
  • Rugby
  • Horses
  • Cricket
  • Tennis
  • eSports
  • Golf
in play betting sites

In-play betting can make even a boring tennis match exciting.

Leo’s sportsbook is mobile optimised, but not necessarily the best option if you solely use a desktop for in-play betting. For desktop-only live betting, you should head over to Betway’s sports section. It’s smoother on a desktop than Leo’s, and they offer pretty much the same sports and leagues as LeoVegas does.

Best Site for UFC & Boxing Betting: Mr Green

You’ll find a huge amount of markets for UFC and boxing betting at Mr Green and Bet365. For the biggest fights, you’ll also get markets such as over/under round betting and method of victory. And yeah, you’ll get live odds too.

For UFC and boxing, there’s always various markets to bet on for the main card of noticeable fight nights at Mr Green. For the undercard, you’ll typically see a market for the bout winner and over/under round betting.

It’s common for markets to open the closer the fight night gets. You’ll rarely see a lot of markets a week before the fight (unless Anthony Joshua is involved), but on the day of the fight they open more markets and lift their betting limits so you can get more British pounds in.

In case you’re a hardcore MMA fan and follow Bellator or KSW, that’s no problem. Mr Green usually doesn’t have in-play betting available for Bellator or KSW, but you’ll always get bout odds for these fights too.

Best for eSports: Unibet

Unibet, Betway,, and Pinnacle are by far the best sportsbooks for your eSports betting. They don’t just stick to the majors, as they offer lots of smaller tournaments like Hellcase Cup in CS:GO. In addition to the obvious esport games like League of Legends and CS:GO, Unibet also got games like Call of Duty and Overwatch

Unibet has taken a real stand in embracing eSports. They are the main sponsors of the most famous CS:GO team Astralis. This CS:GO team from Denmark has won multiple major tournaments during the past years, and they are usually HLTV rank #1.

eSports betting can be very lucrative, as there aren’t as much stats available yet for the oddsmakers. While oddsmakers have massive amounts of data for football and tennis, eSports is still a new kid on the block, so you can definitely earn some bob if you know what you’re doing.

Unibet offers so many tournaments and games, in which you have an excellent chance to gain an edge if you have a good grasp on how Fnatic matches up against Cloud9 in CS:GO, or Serral against Classic in Starcraft.

Best for EPL: Rizk

Fancy a cheeky flutter on Man United? Rizk has got you covered. They offer a massive selection of football odds from all over the world.

Rizk also has a lot of more exotic variants than just normal match betting. If you want to place a bet when Jose Mourinho is sacked or if Harry Kane remains scoreless in August, Rizk delivers. The classic Betfred with its British heritage is a valid option as well.

Rizk is a brilliant choice for football betting.

Best for NHL, NFL, NBA and MLB Betting: 888 Sports

888 Sports is the top bookie for major US sports leagues. It’s a sister site of the famous 888 Casino. They offer a vast amount of markets for every game for each of the biggest sports. They excel in NFL, where you’ll find tons of betting options from regular match betting to player props like Tom Brady’s over/under yards.

You can bet each sport in-play, too. Come playoff time, they’ve got every game on offer, and you can bet all the action live. In the regular season, you’ll get selected games to bet in-play, but you’re always certain to get at least a game or two for betting live each day. You’ll see the games highlighted with “LIVE!” highlight between the game and the odds section.

You’ll find all the biggest sports at every sportsbook, but you’ll rarely come across such selection that Spin Palace offers. Another great option for NHL or NBA betting is LeoVegas (especially on mobile), while 888 Casino and Rizk are solid options for MLB and NFL.

Best New Betting Sites of 2021: LeoVegas, Rizk

The best new betting sites in the UK have to be LeoVegas and Rizk. Both of them are established operators over in Northern Europe, but now they’ve brought their A-game to the UK, too. Tasty bonuses, UK-friendly payment methods, and sports that we Brits are interested in all play a part.

Currently, Rizk offers no welcome customer offer. At LeoVegas you’ll get an in-play 100% profit boost up to £100 with a £10 max stake. The good thing about the offer is that the profit boost is paid in cash with no wagering requirement.

Get LeoVegas 100% profit boost:

  1. Get your LeoVegas sportsbook bonus:
  2. Fill the sign-up form
  3. Click “My account”
  4. Click “Deposit”
  5. Choose your deposit method (you don’t need a bonus code)
  6. Confirm the transaction
  7. Make £10 in-play bet using your mobile. Your profit will be boosted 100% up to £100 if the bet wins.

Online Sports Betting in the UK 2021

Here’s some random tips and tricks on how top UK betting sites operate. So we’ll go over how you can get your money in and out, if you need to pay taxes (yuck!), and more.

Deposit and Withdrawing

Getting your money in and out of sportsbooks is easy. The easiest ways are to use debit cards like Visa and Mastercard, PayPal, E-wallets such as Neteller and Skrill or Ecopayz. Depositing is instant, while withdrawals take a couple of days.

The most popular banking methods:

Online bookies have made it easy for people in the UK. They’ve brought on deposit options familiar to us like Paypal, E-wallets and Pay by phone.

Getting your money out is easy, although a bit slower than depositing. The most common way is to cash out winnings is to receive the funds to your bank card. Unlike deposits, cashouts aren’t instant. They take about 1h – 2 days to clear depending on the site. Then it takes another day or two until the funds are on your account.


Is sports betting income taxed in the UK?

In short, no. The UK Government gets its slice of the pie directly from bookies. There's no tax for punters to pay on either bets or any winnings in the UK.

What is spread betting?

Spread betting is a relatively new way to bet on sports. It's also an exciting way of betting and can be much more profitable than traditional betting on fixed odds. Here's an example of how it works.

If you think Liverpool will win the Merseyside derby with a fair margin, you can opt to place a wager with one and a half goal spread. Or if you think there's a decent chance that Everton will be totally demolished, you can select even bigger spread for the Reds. Naturally, it also pays off bigger. If the traditional fixed odds for the Liverpool win would be something like 1/2, with a spread bet of -2.5 Liverpool you might get odds of 4/1 or something close to that.

Where can I get the best UK free bets bonus?

Mr Green offers two £10 free bets for UK players. You just need to wager £20 at Mr Green betting and you will receive two 10 quid free bets. Please note that these free bets are valid for 7 days.

What is an accumulator?

An accumulator bet, or "an acca", combines multiple selections on a single bet. For the bet to pay out, all selections must come true. Accumulator betting is super popular in the UK and why not? With an accumulator bet you'll have a chance to rack up massive odds and potential winnings with a low stake.

An example of Premier League acca:

  1. Wolverhampton to beat Tottenham at 3/1
  2. Liverpool to beat Man City at 3/1
  3. Man Utd to beat Newcastle at 2/1
  4. Crystal Palace to beat Everton at 4/1
