Top 5 Sportsbooks That Offer Bonus Bets in the UK

You’ll find many sportsbooks in the UK that offer bonus bets to new and existing users. However, finding quality sites with top offers and friendly terms can be daunting. If you're interested in exploring free bet offers in the UK, I've reviewed some leading sites that feature bonus bet promotions you’ll find ideal. Check them out below:

Betfred — Best for Football and Racing Bonus Bets

Betfred Sportsbook: Pros and Cons

• Comprehensive coverage of popular British sports
• In-play betting options with live streaming
• Mobile app

• Limited international racing markets

If you’re into football or horse racing, Betfred is a great choice. It’s one of those classic UK bookies that still delivers, especially when it comes to bonus bets around big matches or race days. The site’s easy to use, and everything feels familiar if you’ve bet online before.

Betfred's flagship welcome offer, which splits your £50 bonus entirely into 3 x £10 standard free tokens and 2 x £10 accumulator tokens, provides an incredibly versatile toolkit to attack massive field sizes and volatile morning price drifts.

I like that claiming the bonus bets at Betfred is simple and smooth. Just make sure to enter the bonus code to claim this welcome offer. All the terms are well laid out so that you can see the value and requirements. Plus, the website is modern and intuitive, making everything straightforward.

Kwiff — Best for Surprise Bonus Bets and Supercharged Odds

Kwiff Sportsbook: Pros and Cons

• Android and iOS mobile app
• Supports in-play and live streaming
• Random supercharges on payouts

• High odds margins

Kwiff offers a truly unique betting experience by discarding standard flat lines in favour of its signature odds algorithm. It keeps dropping massive, completely random price multipliers onto your active bet slips.

The platform's randomised supercharged engine is running at full throttle, optimised for active Premier League matchday slates and European domestic leagues. Kwiff covers everything from live in-play props to deep tournament outcomes, ensuring that if your live wager gets 'Kwiffed,' you receive a heavily enhanced payout that standard fixed-odds sportsbooks cannot match.

BetMGM — Best for Bet Credit Variety

BetMGM Sportsbook: Pros and Cons

• Sleek UK platform
• Trusted UKGC licensing
• Mobile-first site design

• No phone support

BetMGM is one of the new UK betting platforms, but it has already grabbed the attention of bettors. Its welcome bonus is £40 in bonus bets for a £10 wager, ideal for those looking to explore without a large initial deposit.

The platform boasts a sleek, user-friendly website with alphabetically organised sports, ensuring effortless navigation and bet placement. Advanced betting features further enhance user control and experience.

Betano — Best for Variety and User Experience

Betano Sportsbook: Pros and Cons

• Clean, modern interface with smooth bet placement
• Fast and responsive mobile apps
• Well-established brand

• Fewer niche and non-mainstream sports

I recommend Betano because it’s a quality online sportsbook with a slick interface and loads of markets. You can easily create a new account with the sportsbook by following a few easy steps. The website is intuitive and lets you find your favourite sports and place bets without hassle.

You can claim some top-tier promotions at Betano. The sportsbook offers bonus bets for new and existing users. One of the standout deals I found on the site is the welcome offer, where you can get up to £30 in bonus bets after placing a stake of £10.

Another reason I like Betano is that it is big on football, eSports, and even more niche markets like handball or futsal. So if you’re looking for variety and a bonus to go along with it, Betano’s a strong choice. Plus, the betting types and markets are quite diverse to give you enough options.

Bet365 — Best for In-Play and Live Streaming with Bonus Bets

bet365 Sportsbook: Pros and Cons

• iOS and Android app
• Competitive odds across top sports
• Live streaming available

• No sports loyalty program

bet365 is widely recognised as the UK's premier live-wagering hub, combining a highly responsive user interface with an exhaustive array of data. New users can cleanly claim £30 in free bet credits after settling a simple introductory £10 wager.

This live hub is operating at peak handle with the 2026/27 European domestic football season now underway and the US Open Tennis Championships actively running in New York. By simply maintaining a funded account or having placed a cash wager within the previous 24 hours, you unlock premium, low-latency live streams for courtside and pitchside action.

When paired with their Tennis Retirement Guarantee, which pays out your selection as an absolute winner if their opponent pulls up lame or retires mid-match, bet365 offers elite margin insulation as you deploy your bonus credits across the weekend board.

How to Claim Bonus Bets in UK Sportsbooks

Claiming bonus bet offers in the UK is pretty simple, even if you’re brand new to online betting. I’ll walk you through the process step-by-step so you know exactly what to expect:

1. Choose a trusted UK sportsbook
   Start by picking licensed and reputable betting sites in the UK. You can choose from bet365, BetMGM, Betfred, or any other names I’ve mentioned. You’ll see links to all of them on the banners around this page. Make sure the offer includes bonus bets or bet credits.
2. Create an account
   Enter your details, including your name, email, DOB, address, etc. It only takes a few minutes, and most sites will send a verification email or text before activating your account.
3. Make a qualifying deposit
   This is usually something like £10 using a debit card. Avoid e-wallets like PayPal or Skrill if the terms say they’re excluded; that’s a common mistake. Ensure you familiarise yourself with the terms.
4. Place a qualifying bet
   Most bonus bets require you to place real-money bets. For example, “Bet £10 at odds of 1.5 or higher.” Once that stake settles, your bonus kicks in.
5. Receive your bonus bets
   Once your qualifying bet settles (win or lose), your bonus bets should land in your account, usually within 24 hours. Some sites split them into smaller bets, like 2 x £10 tokens.
6. Use your bonus before it expires
   You’ll typically have 7–30 days to use your bonus bets. And remember, if you win, you usually just get the winnings, not the stake.

Tips for Making the Most of Bonus Bets in the UK

If you want to fully maximise your UK bonus bets, keeping some key tips in mind can be beneficial. I've provided some expert strategies below:

The Top Sports You Can Use Your Bonus Bets on

You can utilise your betting bonus UK on many popular sports in the UK. Here are the options you’ll often find:

• Football
  Many sportsbooks in the UK allow you to use your bonus bets on various football matches. You can use them to place wagers on the Premier League, UEFA Champions League qualifiers, domestic cups, and international fixtures.
• Tennis
  Bet on ATP and WTA Tour markets. Tennis is great for in-play betting with bonus bets. The ultimate window to use your free bets is now open as the US Open Tennis Championships approach. Courtside lines provide excellent stability to meet minimum odds requirements (typically 1/2 or 1/1) while backing top-tier seeds.
• Horse Racing
  Fresh off the conclusion of the historic Sky Bet Ebor Festival at York (19–22 August 2026), bookmakers have turned their focus to late-summer flat action and ante-post autumn features. Look for platforms like Betfred offering extra-place races and Best Odds Guaranteed (BOG) cushions, allowing you to deploy your free bet tokens on live market value shifts with maximum margin security.
• F1
  Formula 1 moves into its European crescendo following the conclusion of the Dutch Grand Prix, heading directly into the upcoming Italian Grand Prix at Monza. Bookmakers offer dynamic qualifying and race-day props for driver podiums, fastest laps, and head-to-head match-ups.
• Cricket
  Popular for both local county games and international matches. You can use bonus bets on Test matches, The Hundred, or the IPL.
• Boxing & MMA
  Bonus bets are often available for big fight nights in MMA and boxing.
• eSports
  If you’re into gaming, you can use bonus bets on games like CS2, Dota 2, League of Legends, and more. Most sportsbooks cover these games with multiple markets.
