Quick facts about bonus bets UK

  • Most UK sportsbooks include bonus bets as part of their sign-up bonuses
  • These offers let bettors place bets on popular sports
  • Bonus bets can be found on top-rated sportsbooks such as BetMGM UK, Matchbook, and Bwin

What are bonus bets?

Bonus bets are a type of bonus available to both new and existing bettors on sportsbooks, allowing you to wager on popular sports like football, basketball, and horse racing without deducting your stake from your account balance. For instance, a bonus bet sign up offer might look like this: new customers bet £5, get £150. This means to claim this offer, you must place a qualifying bet with a £5 deposit to receive £150 in bonus bets.

There are various bonus bets today available for UK bettors, each with different requirements. Some may only require you to sign up with a promo code; no deposit is needed. On the other hand, some of the best bonus bet offers may require a minimum deposit to qualify. These are typically matched deposit offers. For instance, bet £10 to get £10. You can also receive a no-risk bonus sports bet, which is usually awarded to new bettors if their qualifying bet loses.

Additionally, bonus bet no deposit offers and deposit-based may come with wagering requirements before you can withdraw winnings. Always check the terms and conditions of the bonus before opting in.

Keep in mind that while bonus bet offers may be found on real money sportsbooks, you can also enjoy these offers on free betting sites UK.

Top sportsbooks with the best bonus bets UK

Having tried several bonus bet offers from different sportsbooks, here are the UK sportsbooks currently offering the most rewarding bonus bet offers:

BetMGM UK – Offers two sign-up offers to choose from

Matchbook – Offers a variety of bonus bet offers for all bettors

Matchbook doesn’t hold back when it comes to bonus bet offers. New UK bettors can choose from multiple welcome promotions, including a Bet £30, Get £30 in bonus Bets offer.

To claim this, simply sign up using the promo code displayed in the banners on this page and place £30 on Matchbook Exchange markets. To qualify, your bets must be placed and settled at minimum odds of 2.0, cover at least four separate events, and be on singles, multiples, or Bet Builders.

To claim it, simply opt-in via the promotions page, place and settle £30+ in multiples from Monday to Sunday, ensuring your multiples have 3+ legs and minimum odds of 3.0, and you’ll receive a £5 Bonus Bet every week.

Before signing up, I was eager to explore the sportsbook and Matchbook delivered. Bettors can wager on top sports like American Football, Basketball, Cricket, Golf, Horse Racing, Ice Hockey, Soccer, and Tennis.

How to make the most of your bonus bets UK bonus

Finally, you've found a bonus betting bonus UK that catches your interest, but do you know how to maximise your offer? Here’s how:

📝 Opt into the promo

It's not enough to just sign up; most bonus bet promotions, like the one on BetMGM, require you to opt in before you can participate. Navigate to your account settings and select the option to join bonus offers. It’s a simple step, but skipping it could mean missing out on the deal.

📊 Make informed predictions

If you're betting on a football match, your decisions should be well-informed. To do this, use an odds calculator, and check the latest reports, including injury updates and team performance. Analyse which team has the upper hand and place your bet based on solid research rather than guesswork.

📜 Read the terms and conditions

Every bonus bet has its terms and conditions, so read them carefully to avoid surprises. Some offers can’t be combined with other promotions, while others may have expiry dates and wagering requirements. Knowing these details ensures you don’t miss out on your bonus.

🛠️ Use responsible gaming tools

Stay in control of your betting experience by using responsible gaming tools. Set time limits, deposit limits, or even self-exclusion if needed. These tools help anyone maintain a healthy betting habit.

🎁 Take advantage of other bonuses

Many sportsbooks allow you to claim additional promotions alongside your bonus bet. For example, you might be able to use a referral bonus or take advantage of odds boosts. Don’t limit yourself; explore other offers to maximise your rewards.

🚫 Avoid exclusion triggers

Specific actions can disqualify you from a bonus bet offer. These may include misusing a promo code, placing a bet with bonus funds, or even sharing a home address with another bettor. Be mindful of these restrictions when claiming your bonus bets UK to ensure you remain eligible.

✔️ Verify your account

Unverified accounts may not be able to access bonus bet winnings. Complete your verification process before claiming any bonus to avoid issues later. Remember that sportsbooks may still request additional verification, such as a photo of you holding your ID, even after a win.

💬 Contact customer support if needed

If you’re having trouble accessing your bonus bet, contact customer support for assistance. Live chat is usually the fastest way to get a response, but from experience, email can also be effective, especially if the support team is reliable.

Benefits of claiming a bonus bet

There are plenty of advantages to claiming a bonus bet, but based on my experience, these appeal the most:

1. No risk involved

Since bonus bets don’t deduct funds from your account, you’re never at a loss, whether your bet wins or loses. It’s a great way to engage in betting.

2. Opportunity to cash out

Winning a bonus bet usually means extra cash in your account. By taking advantage of these offers, you can build up your balance without spending your own money.

3. Test a sportsbook

Bonus bets provide a risk-bonus opportunity to test a sportsbook's offerings strategically. This allows you to try the site's features and user experience, test the redemption process and withdrawal processing time before becoming a loyal bettor of the sportsbook.

4. Explore different sports

Usually, bonus bets aren’t limited to just one sport; they’re available for football, basketball, horse racing, and more. By claiming them, you experience new sports and betting markets, build confidence in your betting decisions while minimising potential losses. Ultimately, you expand your knowledge and increase your chances of winning your bets.

Conclusion – Bonus bets UK are available for new and existing bettors

From my experience, new and existing bettors can claim bonus bets across various sportsbooks. These bonuses are often available for popular sports like football, basketball, and horse racing. If you're looking for the best offers, consider sportsbooks like BetMGM UK, Matchbook, and Bwin. They offer generous welcome bonuses and cover a wide range of sports. Plus, new users on BetMGM UK, Matchbook and Bwin can choose between two sign-up offers, giving you more flexibility when getting started.
