Why Free Bets Still Matter
Let’s be honest, punters love a free bet—and with good reason. They give you a risk-free way to test a site, build your betting pot, or try an acca without the usual sting.
But not all free bets are equal. Look for:
- Low wagering (or none at all, like Betway’s spins)
- Real value for your usual bets (accas, football, horse racing)
- Weekly loyalty rewards (Betway and 10Bet do this well)
Are these offers safe to claim?
Yes. All the sites listed are licensed by the UK Gambling Commission.
Do I pay tax on winnings?
Nope. Winnings are tax-free under UK law.
Can I use e-wallets like PayPal?
Some sites exclude Skrill/Neteller/PayPal from promos. Stick to debit cards for bonuses.

Which UK Bookmaker Is Best for Free Bets & Why?
The UK betting scene in 2025 is packed with choice. But if you’re wondering which bookmaker is actually worth signing up with—especially for free bets and new smart betting features—we’ve taken a close look.
Let’s break it down.
Bet365 – The All-Round King of UK Betting
If you’re only going to join one bookie, Bet365 is arguably the one. The £30 in free bets welcome offer is solid, and you only need to bet £10 to unlock it using code 365GMBLR. Even better? If you only stake £5, you still get £15 in freebies.
But what really sets Bet365 apart are the in-play betting options, early payout bet offers, and virtual sports. Fancy a punt on the Grand National? Bet365 matches the best price offered by Ladbrokes or William Hill, thanks to its ITV Racing Price Promise. Football fan? If your team goes 2-0 up, your bet is paid out—even if they bottle it and draw.
You could use a free £10 bet on a Saturday 3pm Premier League match and cash in early if your team goes two goals clear. No stress. Plus, their app is slick and covers more markets than any UK competitor.
Betfred – Best for Football Accas & Horse Racing Betting Users
Betfred is a fan favourite on the high street and brings that same energy to its app. The Bet £10, Get £30 in free bets offer is one of our favourite welcome deals among bookmakers —just make a qualifying wager at odds of Evens (2.0) or higher.
Where Betfred really shines is in football accumulator betting. Their Acca Flex promo gives you a cash refund if one leg of your 5+ fold lets you down. That’s handy when you’re backing an EFL acca and one team blows it in stoppage time.
They’re also one of the best for horse racing, with live-streaming, Racing Post tips, and “Extra Places” on big race days. You can even tweet them with #PickYourPunt, and they’ll price up your custom bet.
10Bet – Great for Niche Sports & Acca Boosts
Looking for something beyond football and racing? 10Bet is a sleeper hit with an excellent app and loads of sports like MMA, winter sports, and even snooker. The 100% matched deposit up to £50 (with code SPORT) gives you more flexibility than your usual bet-get deal.
Their Acca Boosts are proper value—land a 5-fold and get a 10% profit increase. Go bigger, and you could earn up to 100% extra on your acca. Try this during the Six Nations or when betting across different tennis tournaments in one go.
Also worth mentioning: they’ve got quality virtual betting options, running every few minutes, and in-play markets that cover “Next Goal” or “Total Corners” markets during live matches.
Betway – Solid for Weekly Rewards & Free Spins
Betway combines a decent sign-up offer with solid ongoing promos. You’ll get a £30 free bet if your first acca loses, plus 50 free spins on Big Bass Bonanza—great if you fancy a flutter in both sports and casino.
They also run a Free Bet Club, handing you £10 in free bets every week if you opt in and place £25 worth of accas. That’s easy to hit if you’re placing regular weekend football multis.
For Cheltenham or Ascot, Betway Boosts often offer enhanced odds on specific horses or jockeys, making your punt that little bit sweeter.
Mr Play – Better Than You Might Expect
Often overlooked as just a slots site, Mr Play has quietly built one of the best betting apps for casual punters. The Bet £10, Get £10 deal is easy to claim (use code AGPLAY) and there are generous acca boosts up to 77% for bigger bets.
Use your free bet during a Champions League midweek fixture, and if you land a 4+ fold, you could earn an extra 10–20% on your winnings. Plus, their bet builder is easy to use—combine corners, bookings, and goals all into one wager.
Common Bonus Types from UK Bookies
UK betting sites use different kinds of bonuses to reward both new and existing punters. Here are the most common ones:
- Welcome Free Bets – Bet365, Betfred, Betway all offer £30+ just for signing up and placing a small qualifying bet.
- Matched Deposit Bonuses – 10Bet and Unibet match your first deposit up to £50 or £100.
- Acca Boosts – Get bigger returns on accumulators. Great on football or golf events.
- Risk-Free Bets / Insurance – If your first bet loses, you get it back as a free bet (e.g. Betway).
- Weekly Loyalty Rewards – Betway and 10Bet offer free bets if you wager a certain amount each week.
