With the online sportsbook marketplace becoming even more competitive as new betting sites enter the fray each month, bettors are being bombarded with free bet offers, new bonuses and promo codes like never before. Every bookie wants you to sign up with them, but there’s just not enough time in the day to give them all a go. Fortunately, you won’t have to.

There are a bunch of welcome bonus offers out there, but there are also a few promotions for existing players too. Whether you’re looking to grab a bonus at a top football betting site, or want a bonus for betting on tennis, our quick guide to sports betting bonuses will give you everything you need to know to pick out the best bonus for you. Once you’re done, you can choose from our list of best betting sites – we’ve only picked out the best on the market.

Quick Reviews for the UK's Best Sports Betting Bonuses

  • HeySpin welcomes new users with a £10 free bet. To get this offer, simply deposit and bet £15 on the site. You can place this first bet on any sport, and there are loads to choose from. Among the site’s markets, I found some less familiar options like stock car racing and floorball, alongside all the usual favourites. HeySpin currently has just one ongoing promotion for regular punters, called the Combo Boost. It adds extra winnings to combo bets, with the percentage bonus ranging from 4% to 77%, depending on how many picks you include in your bet. Being honest, I would love to see additional options for betting with bonus funds, especially a bet club. However, with perks like early cash out and a bet builder that allows you to roll up 30 different markets from the same match into a single bet, I enjoyed the experience here regardless.

    pros icon Pros:
    • Free £10 bet for new bettors
    • Combo Boost promotion
    • Diverse range of markets, including niche sports
    • Integrated casino games
    • Offers cash out and bet builder features
    cons icon Cons:
    • Limited ongoing sports betting bonuses
    • PayPal, Neteller, Skrill, and Paysafecard excluded from sign-up bonus
    • Only one welcome bonus per user across all Aspire Global sites
    • Uninspiring site design
  • Horse racing fans might want to consider 10Bet, where best odds are guaranteed on all events, and punters will receive their money back as a free bet if their horse loses by a neck or less. 10Bet also offers an acca boost up to 50% on bet slips that have three legs or more. For new customers, there’s a 50% up to £50 welcome bonus available, unlocked by a minimum deposit of £15 and a PLAY10 bonus code. I didn’t think this was a particularly impressive offer but still a decent way of getting an extra chance to test out the site. Bets placed using bonus funds must be placed on events with minimum odds of 4/5 for singles and 2/5 for accumulators. The big disappointment for me was that wagering requirements are quite steep at 8x the deposit and bonus, however you do have 60 days to fulfil them.  

    pros icon Pros:
    • Best odds guaranteed on all horse racing events
    • Acca boosts and money back promotions
    • Huge range of betting markets
    • Native app
    cons icon Cons:
    • High wagering requirements on welcome bonus
  • At the time of writing, Bet Storm offers specific promos on football, cricket, rugby, tennis, horse racing, basketball, F1, MMA, darts, table tennis, ice hockey, volleyball and esports events – and some of these sports will be able to enjoy via the site’s live stream. For me, this is a first-class range of promotions, offering punters the chance to wager in the sport they’re most familiar with. New members can claim £10 in free bets when depositing £10 of their own, and these must be placed on events with minimum odds of 1/2. Those taking part will need to wager their winnings 1x and will have seven days to do so. Bet Storm’s Wager Wars feature also allows punters to place on leaderboards in a bid to win additional cash prizes. 

    pros icon Pros:
    • Live streaming available
    • Loads of promos targeted at wide variety of sports
    • Wager Wars offers extra prizes
    cons icon Cons:
    • No native app
  • One of the best things about Luckster is that this betting site offers customers the chance to boost their acca odds by up to 77% on some pre-match markets. There’s a £10 free bet on offer once you’ve deposited and wagered your own £10, and this welcome offer comes with no wagering requirements and requires bets to be placed on events with minimum odds of 1/1. Navigating my way around the site was really easy and I liked the fact I could favourite certain sporting events and come back to them at a later date. A really easy site to work with, and a handy pop up betting slip in the corner of each page. 

    pros icon Pros:
    • Up to 77% acca boost available on some bets
    • No wagering requirements on welcome bonus
    cons icon Cons:
    • Site sometimes prone to glitches and broken links
    • No native app
  • Live streaming is one of the hallmarks of a great betting site, and I was pleased with the amount of options available on Unibet, meaning you can witness the action in real time while you bet live. The welcome bonus is offered as your money back if your first bet loses, requiring a minimum bet of £10. This comes with a wagering requirement of 3x, and Unibet will also chuck in a £10 bonus to use on the site’s online casino. Existing members will be able to make use of a range of other promotions too, including best odds guaranteed on all horse racing events and daily odds boosts on tennis events. Oh, and there’s £150 up for grabs for anyone who refers a friend to sign up.

    pros icon Pros:
    • Live stream availability
    • Betting welcome offer includes a £10 casino bonus
    • £150 for those who refer a friend
    • Native app
    cons icon Cons:
    • Welcome bonus could be more generous
  • 32Red offers a wide range of sports markets on everything from cricket to motorsports. The sportsbook is neatly laid out and never feels cluttered, which isn’t something I can say about every betting site. If there’s a drawback, it’s that there aren’t many bonuses for sports bettors. Even the site’s welcome offer is aimed at casino players, offering a 150% up to £150 deposit match to use on slots and games. On the bright side, I found the site fantastic for betting on horse racing. There are price boosts for every UK and Irish meeting, and you can watch the races thanks to the site’s excellent live streaming feature – accessible when you place a £1 bet on the race. For sports like tennis, football, and basketball. I didn’t even necessarily need to place a bet to access the streams; all I needed was a funded account. 

    pros icon Pros:
    • Daily horse racing price boosts
    • Live streaming options
    • Neat site design
    cons icon Cons:
    • Promotion focused on the casino
  • Vegas Mobile Casino has been entertaining players since 2013, expanding its offerings to bettors by adding a brand-new sportsbook in 2022. I was able to claim a £30 free bet when I signed up for a new account here, though I did need to place bets to the value of £20 to unlock the reward. Nonetheless, I found this a fun way to get started. Better still is that the promotions page revealed a weekly bet club is available. This is my favourite type of offer, though once again, the qualifying requirements are a bit strict. With this weekly promotion, punters must deposit and bet £50 to get a free £20 bet. Vegas Mobile Sports also offers cashback deals and leaderboard-style contests for bettors, available on a wide range of sports such as the Premier League and MMA. So, overall, I think bonus hunters will find plenty to like! 

    pros icon Pros:
    • £30 free bet for new bettors
    • Regular promos, including a bet club and cashback
    • Excellent live betting features
    • Free live streaming for select sports
    cons icon Cons:
    • Site design could be improved
    • Neteller and Skrill deposits excluded from offers
  • The Tebwin sign-up offer is a £10 free bet, which you can unlock by depositing £10 and then placing bets to the value of £10 or more. After that, you’ll want to hit up the promos page to take advantage of this bookie’s great choice of betting bonuses. For example, you can enjoy real money betting on tennis and get 10% cashback on your deposit losses when you pay in £10+ using promo code ‘NET’. While you can claim up to £500 cashback from this deal alone, Bet UK also offers cashback on big sporting events like the World Cup and the Cheltenham Festival — so there should always be a way to put a bit of money back in your pocket. Tebwin is a great site in terms of design – I really like the football pitch background and the clearly laid out sports markets down the left hand side. You can store your favourites for next time you’re on the site and the live calendar is a handy way of checking out what’s available to bet on. 

    pros icon Pros:
    • Only 1x wagering on bonus bet winnings
    • Bettors can place multiple bets to qualify for free bet offer
    • Pre-match and live betting, with lots of different sports on offer
    • Wide range of payment options for UK customers
    cons icon Cons:
    • Max winning cap of £200 applies to free bet
    • Only one welcome bonus across all ProgressPlay-powered sportsbooks
    • Only seven days to use free bet and complete wagering requirements
    • Skrill excluded
  • Eagle-eyed football fans will remember Bwin from its sponsorship of Real Madrid during the Cristiano Ronaldo and Kaká years. Excited to check out the site, I was immediately impressed with the smart black, white and yellow branding and straightforward site design. Digging a little deeper, Bwin offers a nice range of betting bonuses, including a £20 backup bet for new customers. Additional promotions include enhanced accas and best odds guaranteed — there are even tutorials available that walk you through how to use each type of offer. It was easy to find markets that appeal to me thanks to the simple search function and the calendar, where I could browse matches by start time. There’s also the option to add leagues and competitions to your favourites for easy access.

    pros icon Pros:
    • Slick site design
    • Bet insurance for new customers
    • Good range of recurring betting bonuses
    cons icon Cons:
    • No free bet in the welcome offer
  • BoyleSports offers new customers £40 in free bets when they sign up and bet £10. Considering there are many similar sign up bonuses on the market offering £30 or less in free bets, BoyleSports’ offer is a strong start. As for the range of betting bonuses for existing customers, what stood out to me was the strong horse racing and greyhound coverage. Punters can benefit from best odds guaranteed, money back if second to SP favourite, extra place races, and much more. For those interested in other sports there’s less to be excited about, although I’m a big fan of the acca rewards on offer, including a free bet if one leg loses and boosted winnings up to 100%. The BoyleSports site is well designed and easy to use — I found the bet calculator and blog particularly helpful when researching my first bet.

    pros icon Pros:
    • Generous welcome offer
    • Huge range of horse racing promotions
    • Excellent acca rewards
    • Bet calculator and blog
    cons icon Cons:
    • Fewer promos on other sports
How We Review

How We Review the Best Online Bookies

When reviewing sites for the best betting bonuses, we take a variety of factors into consideration. You’ll find some of our top criteria below.

  1. Bonuses and Promotions

    The first thing we check out is the promotions page and we expect to find a decent range of regular offers alongside your usual welcome bonus. A new bettor is likely to choose a particular operator off the back of a welcome offer, and once registered and familiar with the set up, it’s often easier to stay put rather than test the waters with another new betting site. Because of this, we scrutinise the available bonuses for existing customers — not only the direct bonus you receive but the terms and conditions by which they are defined.
    Terms and conditions — which usually include tough wagering requirements, time limits that can vary from a few days up to a month, winning caps and odds limits — can really make or break a promotion, usually including Deposit limits are another condition we look out for, and naturally we favour bookies that reward punters with decent returns from smaller deposits. Coral, for example, treats punters to a low qualifying deposit, offering £20 in free bets in return for a £5 deposit.
    Our favourite sites run promotions to suit players of all tastes, whether it’s on the UK’s favourite sports or less mainstream events like MMA and esports.
  2. Licensing and Safety

    We take player safety seriously, but we’ll try not to bore you with the legal stuff. Here’s the deal: we only check out and suggest online bookies that have the UK Gambling Commission’s seal of approval. This means they play by the rules, meeting regulatory standards and offering a safe environment for you to enjoy betting with bonuses.
  3. Sports, Markets and Odds

    We love telling you about the fun side of betting and how to make the most of your bonus offers. For each site we review, we check out the variety of betting options available, including sports, virtual games, e-sports, and even non-sporting events like politics and TV. We ensure that free bets and bonuses work across a wide range of sports and markets, while also looking out for cool features like bet builders, accumulators, in-play betting, and early cash-out. Competitive odds are key to boosting the value of your bonuses, so we aim to highlight the bookies that will offer you the best prices for your bets.
  4. Terms and Conditions

    As part of our review, we pick through the T&Cs of bonus offers to give you a clear idea of how valuable promotions really are. Remember, it's not just about the bonus amount, the small print matters too. We consider things like the minimum bet odds, any payment restrictions, time limits, and wagering requirements. Understanding how these rules can affect your betting experience is crucial. Factors like how many times you need to bet and how quickly you have to do it can make a big difference. So, breaking down these bonus terms is one of our main focuses.
  5. Payment Options

    The best UK betting sites with bonuses work hard to make things convenient for punters, offering various ways to deposit and withdraw money, including options like debit cards, PayPal, and Paysafecard. Our bookmaker reviews aim to keep you informed about which of these payment methods are eligible for bonuses. We’re particularly interested in methods like e-wallets, Trustly, and Visa Fast Funds because they often make it quick and simple to get money in and out of your account, making it easier to claim and use your bonuses.
  6. User Experience

    The best betting sites offer thousands of betting options, giving you plenty of choices. What's crucial, especially when using your bonuses, is smooth navigation between different sports and bet types. Top bookies make it easy to find your way around. They also include handy features like bet trackers to help you keep an eye on your bets, notifications to stay updated, and the ability to save your favourite bets to save time. The most outstanding sites even let you request custom bets and watch live streams of various events. All of these features make your betting experience smooth and enjoyable, especially when you're using bonuses to make the most of your bets.
  7. Mobile Compatibility

    With so many of our readers opting to play on mobile or tablet, compatibility with handheld devices is a must for any sports betting site worth its salt. A mobile site accessible via the browser is the minimum here, but what really gets us excited are sports betting apps. These apps come with a bunch of benefits, especially when it comes to using your bonuses. These apps not only offer faster loading times but also provide push notifications to keep you updated on the latest promotions. Better still is that some of these apps even offer exclusive betting bonuses, giving you an extra edge when using your bonuses on the go.
  8. Customer Support

    While your experience at one of our recommended bookmakers should be problem-free, it’s important to know where to go when you need some support, whether it’s with a bonus-related question or any other concerns. We expect to find live chat support, preferably offered round the clock, to address any bonus-related queries instantly. Additionally, phone and email support can be useful.
Types of Bonuses

Types of Sports Betting Bonuses

Let’s explore the various bonuses you’ll encounter at UK betting sites.

Best Matched Deposit Betting Bonus

A matched deposit bonus is a popular welcome offer for sportsbooks and online casinos. It’s a straightforward deal where a punter makes a deposit and it’s matched up to a certain percentage by the bookmaker. 

Take a look at 10bet’s current deal:

  • 50% up to £50 welcome bonus
  • Wager a total of 8 times deposit + bonus

In this scenario, a £10 deposit would return a £5 bonus. You’ll also notice the inclusion of wagering requirements in this offer — this stipulation applies to virtually every matched deposit bonus, but the terms tend to be more player-friendly for betting bonuses than casino deals.

Matched Bets

Matched bets are largely the same as matched deposits. The only difference here is that the bookmaker will credit new customers with their bonus funds once they’ve placed your first bet, rather than making your first deposit.

One example of a current matched bet comes from Luckster, where players making their first bet of £10 will receive another £10 to wager on the site – no wagering requirements attached. 

Best Free Bets Betting Bonus

Free bets are the most common betting bonuses on the market. Regularly available as part of a sign up bonus or as an offer for existing customers, free bets allow you to have a punt at no cost to yourself.

Take a look at Parimatch‘s current deal:

  • Bet £10 Get £20 in Free Bets
  • Odds of 2.00+

With this deal, the £20 in free bets is split into four £5 bet tokens and there are no wagering requirements. If you stick around, you’ll likely pick up additional free bets in the run-up to big matches.

Risk-Free Bets

As the name suggests, this is the safest bet you can get. If you don’t land a winner, you get your stake back! There is a small catch with this type of free bet offer – the maximum amount refunded is usually capped. Plus, the returned stake is usually in token form, so it’s non-withdrawable. That aside, this is still a decent offer that allows new customers to bet with a little more confidence knowing that at the very least, they’ll have their stake returned as a free bet.

Best Money Back Betting Bonus

Money back bets are very similar to risk-free bets but have a slightly wider scope. Again, in most cases you’ll get your stake returned either in cash or bet tokens if your first bet is a bust.

Take a look at Unibet’s deal:

  • Minimum deposit of £10
  • Money back up to £40 plus £10 casino bonus if your first sports bet loses

Be mindful that this bonus expires after 7 days and there are quite steep wagering requirements of 50x attached to the casino side of the offer. In addition, there’s a minimum odds requirement of 2/5 (1.4) plus restrictions on which sports are eligible as your initial wager. Racing fans take note any wager on the dogs or horses are ineligible.

 

No Deposit Bonuses

No deposit bonuses do exactly what it says on the tin – new customers can claim a betting bonus without making a deposit. While you’ll usually find this kind of offer at online casino sites, there are a few bookmakers that are now giving punters the chance to get in on the fun too. All in all, this is a great option for punters who essentially want to try before they buy.

Promos

Other Sports Betting Promotions

The best online bookmakers offer a great selection of frequent promotions for new and existing UK customers. Whereas bonus offers are designed to attract new customers, promotions reward returning customers. Let’s take a look at some of the more common promotions available at UK betting sites.

Frequent Price Boosts

Price boosts see bookies offer improved odds on particular markets. These promotions are  often applied to high-profile sporting events, such as a marquee Champions League fixture. Some bookies also offer price boosts on certain outcomes as part of an accumulator bet. These are often referred to as ‘enhanced accas’.  

Example: For example, Bet365 currently offer a bet boost for selected runners on all UK and Ireland horse races, plus with certain markets in other sports. 

Acca Insurance

Acca insurance is when you receive your stake back when your accumulator loses by one leg. These promotions are a great option if you’re uncertain about one of your selections, or just want a safety net. This bonus will often only be applied to selections above a certain threshold, such as 5 legs or more, and your stake will most likely be returned as a free bet. 

Example: If you were to bet on five Premier League results this weekend, and four out of five came through, with Unibet’s acca insurance you would get your stake back as a free bet. 

Accumulator Bonus 

This fairly simple betting site offer can drastically improve the value of your accumulator. With an accumulator bonus, bookmakers reward you for adding more bets to your football accumulator.

Example: Bet365 gives bettors a 5% bonus on a treble acca that can be boosted to a whopping 90% bonus for a 13-fold.

Request a Bet

Request a bet promotions allow you to request odds for a market that isn’t on offer at your chosen betting site.  Many bookies allow you to get in touch on Twitter, or even create your bet request on the betting site or app.  

Example: At Betfair, you simply need to tweet your requested bet with the hashtag #oddsonthat and a member of the team will quickly get back to you.

Bet Builder

Like Request a Bet, Bet Builders allow you to create bespoke bets with unique betting odds. However, they aren’t made up of markets otherwise unavailable from a bookie. Instead, Bet Builder bets are multiples — the key difference from regular accas being that they’re put together with bets on the same match or game, rather than with bets on different events. 

Example: Using the HeySpin Bet Builder, you can create custom wagers and hopefully winning match multiples on many sports including football, cricket, ice hockey, rugby and baseball.

Free Bet Clubs 

Free bet clubs reward frequent bettors with a free bet on a weekly basis, providing they have placed a certain number of qualifying wagers in the week. Just like any free bet, these will come with other terms and conditions, so make sure you read the fine print before you sign up.

Example: PaddyPower’s Rewards club offers players a free bet of £10 if they place a minimum bet of £5 or more.

Bonus Terms and Conditions

Bonus Terms and Conditions

A betting bonus will often come with a variety of terms and conditions that affect how you play. It’s therefore very important that new customers check the small print to see what T&Cs apply and how they can be met. Let’s have a look at the bonus T&Cs you are most likely to come across.

Wagering Requirements 

Wagering requirements are one of the most common conditions attached to betting bonuses and will invariably have a big effect on how you play. They stipulate that before you can claim any winnings from a bonus, you have to first wager the value of your qualifying bet, your bonus amount, or a combination of the two, a set number of times. 

Let’s take 10bet’s £50 welcome bonus as an example. 10bet states that before you can claim either your bonus winnings or funds, you have to first wager the value of the bonus and deposit 8x. 

Wagering Requirements
x5 x20 x35 x50
BONUS FUNDS £5 £25 £100 £175 £250
£10 £50 £200 £350 £500
£25 £100 £500 £875 £1,250
£50 £250 £1,000 £1,750 £2,500
£100 £500 £2,000 £3,500 £5,000
£250 £1,000 £5,000 £8,750 £12,500

Minimum Odds 

Minimum odds requirements will usually be attached to your qualifying bet. These minimum odds will often be low — usually between 1/1 and 1/3 — so it shouldn’t be too hard for new customers to fulfil the betting requirements. 

Minimum Bet 

With bonuses like free spins or matched deposits there is almost always a minimum amount you’ll need to bet or deposit in order to claim the bonus. Bzeebet’s bet £10, get £10 free bet, for example, requires you to deposit and then place a minimum bet of £10 in order to claim the welcome bonus. 

Maximum Winnings 

There will usually be a max limit on how much you can win from your bonus. The maximum win amount is put in place to protect the bonuses from being abused. Online bookmakers use their promotions to attract new players and reward existing players, but if their customers regularly win big using their bonuses then sportsbooks would lose a lot of money.

Time Limits 

Once new customers have claimed their bonus and worked out how to use it, they will often have to use that bonus and meet the requirements in a set time. If they haven’t met the wagering and odds requirements or used up all their free bets, then the bonus will expire and any winnings will be lost. Some bookies are pretty generous and give over a month’s grace, whereas others may only allow for a few days. 

Payment Exclusions

Be sure to look out for excluded payment methods before accepting a betting bonus. e-Wallets such as PayPal, Skrill, and Neteller are the usual suspects. The reasons for this exclusion can be due to transaction fees placed on the bookies by the payment service itself, plus e-wallets are less robust when it comes to KYC checks. 

Market Restrictions

Be aware that many of the best bonus offers will be restricted to certain betting markets. For example, Unibet allows you to choose from a number of welcome offers based on your preferred betting market. If you’re a football fan, you can choose their ‘Bet £10 on Football, get £30 Football Free Bets’, or if you prefer to bet on the races, you can choose their equivalent offer for horse racing, or greyhound racing.

Mobile Bonuses

Mobile App Betting Bonuses

One of the great things about betting bonuses is that you can claim them on your mobile as easily as you can on a desktop computer. Mobile betting has improved enormously in recent years with many of the best online bookies moving beyond offering fully optimised mobile sites to provide industry-leading mobile apps for Android and iOS. These apps offer plenty of perks. Some of our top picks have app-exclusive welcome bonuses, and as a regular punter, you can often sign up for push notifications to stay informed about the bookie’s latest betting offers and promotions. Whether you’re on the go or relaxing at home, mobile betting apps are super convenient, putting the power to place bets and claim betting bonuses right at your fingertips.

Pros and Cons of Using a Mobile App for Betting Bonuses

Wondering why you might choose claiming a bonus via a mobile betting app as opposed to through your desktop computer? Let’s check out more of the benefits of betting apps and explain some of their drawbacks too

How to Claim

How to Claim a Bonus at the Best Betting Sites

Once you’ve checked through the best betting sites, and chosen your preferred site and bonus, it’s a very simple process to register and start playing. Follow these steps and away you go!

  1. It’s really important to compare all of the best betting sites before making your decision, and this can be done by browsing the tables and reading through our reviews on Compare.bet. Checking for your preferred games or betting markets is an important decider, as is the betting format, bonuses available and ease of use; 
  2. Click through from the table above or the site in question’s review page and follow the registration process – it’s a simple process, adding in details and confirming your identity via KYC checks;
  3. Once registered with your new account, you can make a deposit and claim your first bonus. Be sure to check that the bets you’re looking to make, and the payment methods you’d like to use, are eligible for the bonus;
  4. Now you’re all set to place that first bet. Remember to always stay within your budget, never chase your losses, and always do a bit of research before betting. 
Bonus Types

Betting Bonus Types

Along with the complexities of each sport comes a wide range of betting options available to punters at the best betting bonus sites. Let’s take a look at the most common ones you’ll likely find. 

  • Straight Bets — A straight bet can be used in many team sports and involves making a single bet on one particular outcome — they can be made in games where a points spread is used, such as: 
    • Los Angeles Rams 52
    • Tampa Bay Buccaneers -10
    • This tells you that the predicted score will total 52, with the Buccaneers winning by 10 clear points. The 10 represents the “spread” of the game, or the total points and the margin of victory.
  • Over/Under — An over/under bet allows you to predict whether the total will be above or below a particular number. It can be used on many different sporting events, even down to the number of yellow cards a team will receive. If you reach a push bet where you equal the number given by the bookies, all bets are refunded.
  • Accumulators — Hugely popular with football betting, the accumulator — or ‘acca’ — allows a punter to combine a number of single bets, from multiple games, under one wager. To win, you have to correctly predict all selections of your acca. If even one leg fails, then you’ve lost the bet — unless you’ve gone for acca insurance which promises a refund on your bet if one leg lets you down. 
  • In-Play Bets —  Also known as live betting, in-play bets are placed while the match, or race, is taking place. This type of betting can add real excitement to your viewing experience, and of course potentially lead to some returns if you’ve gauged the flow of play correctly. The best betting bonus sites will have a corresponding mobile betting app that makes it really easy for you to place that in-play wager without missing any of the game.
Cash Out

Cash Out Explained 

An extra perk available at top online bookies like Coral and William Hill, and the perfect companion for in-play betting, a cashout feature gives you the option to collect some winnings or cut your losses before the event in question has concluded. So, if your bet is going well — perhaps five out of your six acca picks have already come in — and you want to secure a profit, cashout is the way to do it. 

On the flip side, if an event is not going how you envisaged, and your bet is looking like a bust, you can claw some of your stake back by cashing out your bet early. If you can’t decide whether to take your money or take your chances, some bookies offer a partial cashout feature that’s the perfect solution. Here, you can cashout part of your bet and leave the remainder to run its natural conclusion. 

Locking in profits on your wagers, no matter the outcome of the event? If it sounds like a great deal, you’d be right. However, it pays to keep in mind that not all bets are eligible for cashout. For example, you can’t usually cash out bets if you’ve used a price boost or a free bet token.

Responsible Gambling

Bet Responsibly with Your Betting Bonuses 

Bonuses like free bets and money back offers can be a good way to bet on your favourite sports teams without spending too much of your own cash. However, here at Compare.bet, we recommend treating even the best betting site bonuses exactly as you would your own money. Click through the link below for top tips on staying safe when gambling and details of organisations that can help you when you need a little advice.

Betting Bonus Frequently Asked Questions

How much do I need to deposit or bet in order to get the biggest free bet bonus?

That depends entirely on the bonus you’re trying to claim. Some bonuses only offer a set amount, like a £10 free bet, so as long as you place the stated minimum qualifying bet you will be able to claim the bonus. Bonuses like matched deposits, however, will increase in value the more you deposit, but this is limited to a certain amount. New customers may be offered a 100% matched deposit, for example, but the amount claimable from it will be capped at £100. As such, depositing more than £100 wouldn’t increase the size of your bonus.

Will I have to place additional bets before I can withdraw my free bet winnings?

If that free bet has wagering requirements attached to it then yes, you will have to place more bets to meet them before claiming your winnings. A bookmaker’s wagering requirements will not be as high as those of a casino bonus, but you will still need to wager a set amount of money in a certain time period to claim your winnings.

Can I withdraw my bonus winnings before meeting the wagering requirements?

No, these bonus winnings aren’t made available in your main cash balance until the wagering requirement has been met, so you won’t be able to make any withdrawals.

Will I need a bonus code to claim my welcome bonus?

While several bookmakers require punters to enter bonus codes when depositing or signing up to become eligible for a specific welcome bonus, this is not necessary in instances where the use of a bonus code is not mentioned beforehand

Can I claim betting bonuses using a mobile device?

Yes, all of the bookmakers you’ll find here offer a mobile-friendly version of their site, and some have mobile betting apps. This means you can claim a sports betting bonus even when you’re on the go. Simply follow our links, as you would on a desktop site, to register an account and become eligible for an exclusive welcome bonus. 

Can I claim a welcome bonus more than once?

No ‒ you can’t claim a welcome bonus more than once on the same betting site. However, some customers sign up for accounts with multiple bookies and claim welcome bonuses from each. That said, you may be prevented from claiming multiple bonuses at sites that run on the same betting platform. This is the case with the ProgressPlay network, for example, which offers a single welcome bonus across all its sites. 

Which is the safest betting site?

All the bookies on Compare.bet have a UK gambling licence. This means they’re overseen by the UK Gambling Commission, and can be relied upon to do business in a fair and secure way. To ramp up your online safety further, be sure to use secure passwords for betting accounts, and set up two-factor authentication in apps when possible. 

What’s the best betting bonus?

There’s no definitive answer to this, instead the best bonus is the one which gives you the best chance of earning withdrawable winnings. If you are a single selection punter, for example, then the risk-free bet is a solid choice, but if you’re likely to place a range of accumulators then a matched deposit bonus offer might suit you better. One thing we are certain of, however, is that you’ll find the perfect bonus for you right here at Compare.bet.

What is a betting bonus?

A betting bonus is an offer or promotion given to users at online betting sites, usually in the form of a matched deposit, free bet, cashback, or bet insurance. Betting bonuses are available at most betting sites when new users sign up and make a qualifying deposit, and you can expect a betting site to offer further promotions once you’re settled in. These may include: weekly jackpots, event-specific offers, VIP rewards, and more.

Which betting offer gives the highest bonus?

At the time of writing, Tonybet has the highest bonus offer at Compare.bet with 100% up to £50. This means that Tonybet will double your first deposit up to £50, given you a potential kitty of £100. Please note that this bonus comes with a 10x wagering requirement, with bets to be placed on odds of at least 1.65. The bonus must also be used, and the wagering requirements fulfilled, within 30 days. Purely looking at bonuses, we don’t recommend offers with such requirements over sites offering free bets. The likes of HeySpin Sport’s free bets offers don’t come with wagering requirements, meaning anything you win with the bonus is yours to withdraw immediately. Always check the terms and conditions to make sure this is the case before claiming.

How can I redeem a betting bonus?

Most betting bonuses are redeemed by making a qualifying deposit or by making a bet with a minimum stake. For example, to claim HeySpin Sport’s £10 in free bets, you must place a bet of £15. The free bets are then added to your account and can be used whenever you like. This differs from site to site, however, with sites like Tonybet requiring you to enter a promo code (TONY50) during the sign up process to claim the matched deposit offer. Check the terms and conditions of each offer before signing up to make sure you know what’s required, or whether certain payment providers are excluded from bonus eligibility.

Is a bonus bet real money?

Bonus bets can’t be withdrawn as real money. However, while it varies from site to site, you can expect any winnings from a bonus bet to be withdrawable as cash.

Can you withdraw a betting bonus?

You can’t withdraw bonus cash or the value of a free bet as real money. However, you can withdraw any winnings from a betting bonus provided you have fulfilled the bonus’s wagering requirements stipulated in the terms and conditions. Generally speaking, free bets are not subject to wagering requirements, but you should always check the T&Cs to make sure.
