We've rounded up five of the best UK gambling sites you simply can't miss this year — trusted, fun, and loaded with features to keep you entertained. So, grab a cuppa, get comfy, and let's find your following favourite site to play on.

1.

Spreadex Sports

If you love having options for sports betting, Spreadex Sports should be right at the top of your list for 2025. This UK-based bookmaker has been around since 1999 — and it's built a solid reputation for giving punters a bit of everything. Whether you're into football, horse racing, rugby, tennis, snooker, NFL, or even greyhound racing, you'll find tons of markets to keep things interesting.

What sets Spreadex apart is how it mixes things up. It's the only place in the UK where you can enjoy sports spread betting and fixed odds betting, and even financial spread betting — all from the same account. So if you fancy switching from a football accumulator to a check on the Premier League footy season points spreads, to then dabble in the stocks on the FTSE, you can do it all without logging out.

Spreadex is also big on in-play betting, which means you don't have to sit around hoping you got it right before kick-off. You can open or close bets while the action unfolds — cash out early to lock in profit or cut your losses if things aren't going your way. They make it easy too, with One-Click Cash Out, Auto Cash Out, and Partial Cash Out options.

Everything is easy to navigate, whether you're on your laptop, tablet, or mobile app. Plus, they keep the trading rooms open 24/7 — perfect for those late-night matches or early morning punts.

New to Spreadex? They've got a welcome offer too: bet £10 and bag £60 in free bets to get you started.

Join and place a £10 fixed odds bet at minimum odds of 1/2 and, once settled, get 3 x £10 free fixed odds bets and 6 x free £5 spread bets. Qualifying bet cannot be cashed out early. Qualifying stakes not included in fixed odds free bet winnings. *Full terms & conditions apply.

If you're after flexibility, variety, and the thrill of spread betting under one roof, Spreadex Sports is worth a look. But it's worth being aware that unlike fixed odds betting, spread betting losses can exceed deposit.

BetTOM

If you're tired of betting sites that treat you like just another number, BetTOM might be precisely what you're looking for. Based right here in East Sussex, BetTOM is a proud UK brand that got its Gambling Commission licence in 2024 — and they've wasted no time partnering with Everymatrix, a top-tier sports betting and casino platform provider.

What makes BetTOM stand out? It's simple — they care about their players. While the big brands leave you chatting with AI bots, BetTOM's experienced customer service team is made up of real people who are ready to help via live chat or email. They'll treat you with respect and genuinely appreciate your business — it's a refreshing change!

On the betting side, you'll find thousands of sports markets, great bet builders, and a safe environment to place your bets. Love the slots? The BetTOM casino is packed with the latest titles from the biggest names in the industry.

They also look after your wallet with perks like Best Odds Guaranteed, acca insurance, same-day withdrawals, and generous welcome offers for new sports and casino players.

All in all, BetTOM feels like a local bookie — but with all the perks of a big one.

3.

10bet

If you're after a betting site that just works well, 10bet is worth a look. It's got that clean, modern vibe — think dark themes with fresh green accents — and it's easy on the eyes whether you're on your laptop or having a cheeky bet on your phone.

Right off the bat, you'll notice 10bet is built with UK punters in mind. Odds show up in good old fractional format by default (5/1, 2/1, you name it), but you can switch to decimal if that's more your thing. The homepage draws you in straight away with big, bold banners of upcoming matches, racing meets, or fight nights, so you know what's hot.

Navigation's a breeze too — the top bar lets you jump between sports, live bets, casino, and promos without getting lost. With over 40 sports covered, it's a proper all-rounder. Football fans get spoiled with 80,000+ events each month, plus horse racing and cricket get special attention too — ideal if you love a Saturday flutter on the nags or catching live IPL.

It's smooth, secure, and easy to use — 10bet keeps it simple, which is precisely what makes it stand out.

4.

DragonBet

Proudly branding itself as the place for Welsh odds, DragonBet offers a refreshing alternative to the big high-street names — and it wears its heritage on its sleeve.

The site's clean look is a nice nod to Wales too: think red and green touches, subtle dragon motifs, and a straightforward layout that works just as well on your phone as it does on your laptop. Odds come in fractional format by default (because we're in the UK, after all), but you can switch to decimal if you prefer.

DragonBet covers all the usual suspects — football, horse racing, tennis, golf — but what makes it stand out is the Welsh focus. Expect top odds on Cymru Premier football, Welsh rugby, and even niche picks like trotting.

Navigation's simple, with a handy sidebar for quick league picks and a top header to switch between sports and in-play action. Daily price boosts on horse racing and Welsh rugby specials help keep things interesting, too.

DragonBet might not be as slick as the big boys, but if you want fair odds and a proper local feel, it's a cracking shout.

5.

Betway

When it comes to covering all bases for UK punters, Betway does tick a lot of boxes. Whether you're backing your favourite Premier League side, eyeing a cheeky each-way punt at Cheltenham, or fancying a flutter on darts or snooker, Betway's sportsbook has it all.

They're especially popular for football and horse racing, but what's nice is you'll find loads of niche options too — from rugby and cricket to international events and smaller markets. Their odds are known to be competitive, and the daily Betway Boosts are a big draw if you like a bit more bang for your buck. If you're into the nags, their Best Odds Guaranteed on UK and Irish horse racing means you won't lose out if the Starting Price drifts in your favour.

Betway's in-play platform is slick too — live stats, streaming on some matches, and plenty of markets to jump on mid-game. Plus, handy features like Cash Out and a solid Bet Builder mean you're always in control.

Regulars can also take advantage of the Free Bet Club — meet the weekly accumulator requirements and receive free bets regularly. For UK punters, it's no wonder Betway's such a favourite.
