🏆 1. William Hill — Our Top Pick for March 2026
Offer: Bet £10 Get £40 in Free Bets | Rating: 9/10
If there’s one bookmaker that needs no introduction in the United Kingdom, it’s William Hill. Founded in 1934, this is a brand that has quite literally shaped British betting culture. And in 2026, it remains our number one pick — not out of sentimentality, but because it consistently delivers across every metric we measure.
For the Cheltenham Festival (10–13 March), William Hill is simply outstanding. Their ante-post markets for the Champion Hurdle, Cheltenham Gold Cup, and Queen Mother Champion Chase are among the deepest in the industry. Their best-odds-guaranteed policy on horse racing means you’ll never miss out if the SP beats your early price — a genuinely punter-friendly feature that not every competitor offers. Head over to our Cheltenham Festival tips and predictions page to pair these odds with our expert picks.
In-play betting is where William Hill truly shines. During Champions League nights and Premier League midweek fixtures, the platform handles high-traffic demand without the lag issues that plague some rivals. Their mobile app — available on iOS and Android — is slick, fast, and genuinely one of the best betting apps UK punters can download right now.
Pros: Best-odds-guaranteed on racing, excellent in-play interface, huge horse racing and football markets, trusted brand with decades of credibility.
Cons: Odds on some niche markets can be slightly shorter than specialist rivals.

2. 888sport — Best for Football Punters
Offer: Bet £10 Get £30 + £10 Casino Bonus | Rating: 8.5/10
888sport has carved out a strong reputation among football fans, and with good reason. Their platform offers a genuinely customised experience — you can tailor your dashboard to surface the leagues, teams, and bet types you care about most. With the Premier League midweek fixtures running from 3–5 March and Champions League ties on 10–11 and 17–18 March, this is a particularly well-timed pick for football bettors. Check our Premier League predictions and Champions League tips for the markets worth backing.
The added £10 casino bonus on top of the sports welcome offer makes 888sport especially appealing if you occasionally dabble across both verticals. Odds are competitive across major football markets, and their live betting interface is clean and responsive.
Pros: Strong football market depth, cross-vertical bonus, customisable interface, reputable operator.
Cons: Horse racing offering isn’t quite at William Hill’s level for Cheltenham enthusiasts.
3. 888sport — Great for Live Betting & Streaming
Offer: Bet £10 Get £40 | Rating: 7.7/10
888sport is a favourite among punters who love to watch and bet simultaneously. Their live streaming library is impressive — covering a wide range of sports including tennis, football, basketball, and some horse racing fixtures. For those following the Six Nations finale or tracking the Champions League drama in real-time, 888sport’s in-play streaming adds a layer of engagement that’s genuinely valuable.
The welcome offer of Bet £10 Get £40 matches the best in the market, and the platform’s interface is clean and user-friendly on both desktop and mobile. 888sport also has a solid responsible gambling suite, including deposit limits and self-exclusion tools that are easy to access.
Pros: Excellent live streaming, strong welcome offer, clean UX, robust responsible gambling tools.
Cons: Some niche markets could be deeper; customer support response times vary.
4. Betsson — European Powerhouse with Sharp Odds
Rating: 8/10
Betsson might not have the same household name recognition in the UK as William Hill, but serious punters know the score. This Swedish operator brings European-level precision to its odds, particularly on football and tennis. If you’re looking for sharp prices on the Champions League Round of 16 ties, Betsson is well worth opening a second account for comparison purposes.
Their mobile app is polished and fast, making it one of the better best betting apps UK contenders for those who bet primarily on the go. Live markets update quickly, and the breadth of sports covered is impressive.
5. William Hill — The Cross-Platform Pick
Rating: 7.5/10
William Hill built its reputation as a casino operator, and that pedigree shows in the quality of its overall platform experience. The sportsbook is a genuine offering in its own right, though — with solid coverage of football, horse racing, and rugby (handy for those Six Nations finals), it’s a smart choice for punters who want to access both casino and sports under one roof. The loyalty programme is also one of the more rewarding in the business for regular players.
6. 10Bet — Competitive Odds & Asian Handicap Specialists
Rating: 7.5/10
10Bet punches above its weight when it comes to odds competitiveness, particularly on football. If you’re a fan of Asian handicap betting — a market that’s become increasingly popular among savvy UK punters — 10Bet is one of the best places to find it. Markets are wide-ranging, and the interface is straightforward without being bare-bones. Well worth a look if you like to shop for value. See our free bets guide to see how 10Bet’s current promotions stack up.
7. Paripesa / Betwinner — Best for International Markets & Crypto
Rating: 7/10
Paripesa and its sister brand Betwinner occupy a unique space in the market. These platforms are built for punters who want access to an enormous range of sports — including esports, virtual sports, and markets from leagues across Asia, Africa, and the Americas that most UK bookmakers simply don’t cover. Crypto payment options add flexibility for those who prefer that route. These are specialist picks rather than first-port-of-call recommendations, but for the right punter, they’re genuinely excellent.
Tips for Choosing the Right Bookmaker This March
- Match your bookie to your betting style: Horse racing fan heading to Cheltenham? William Hill’s best-odds-guaranteed is non-negotiable. Football-first punter? 888sport’s market depth is hard to beat.
- Check the odds before you bet: Never commit to a single bookmaker. Using two or three accounts to compare prices can significantly improve your long-term returns.
- Read the welcome offer small print: Minimum odds, wagering requirements, and expiry dates all matter. A bigger bonus with tighter terms isn’t always the better deal.
- Test the app before a big event: Download and deposit before Cheltenham week — not during it. Apps under peak load behave differently.
- Set a budget and stick to it: Cheltenham is brilliant, but it’s easy to get swept up. Use deposit limits and take advantage of responsible gambling tools every UKGC-licensed site is required to offer.
