What are the best free bets and betting offers in the UK?
If you’re shopping for a new betting account in 2026, the welcome offer is the easiest way to start with a little extra in the bankroll — whether you’re backing the favourite at Royal Ascot, a Premier League acca, Wimbledon or the NFL. The trouble is that the headline number rarely tells the whole story. A “£50 in free bets” splash can come wrapped in five-leg accumulator conditions, while a quieter “£30 in bet credits” might clear in a single afternoon.
So at horse.bet we judge an offer on what actually reaches your balance: the qualifying stake, the minimum odds, how the free bets are structured, how quickly they land, and how good the bookmaker is once the welcome bonus is spent. Every operator below holds a full UK Gambling Commission (UKGC) licence, and all welcome bonuses are capped at 10× wagering — so the small print is friendlier than it used to be. Offers still change, so always check the operator’s own promotions page before you deposit. 18+. GambleAware.org.

Our top UK betting offers explained
1. SBK — Bet £20, Get £50 in Free Bets ⭐ Best Offer Today!
★★★★★ 5.0 / 5
SBK has quietly become one of our favourite accounts to hold — not for the flashiest welcome offer, but for what it does the other 51 weeks of the year. As the sportsbook arm of the Smarkets exchange, it prices markets with an exchange’s discipline, which means its football accumulators and pre-off racing prices regularly beat the high-street names. If you shop around for value, this is the app you’ll keep coming back to.
The welcome offer is: deposit £20, place a qualifying £20 bet at minimum odds of 3.0 (2/1), and SBK credits £50 in free bets as eight £5 tokens over 48 hours. One honest caveat — those tokens must go on accumulators of five legs or more, so this suits multiple-builders rather than anyone wanting a single each-way punt. Worth knowing before you sign up. The app is modern, quick and app-only (no desktop site), and SBK is licensed by both the UKGC and the Malta Gaming Authority.
Who it’s for: value hunters and acca builders who want sharper prices than the traditional bookmakers offer. The catch: free bets are multiples-only, and racing prices are win-only (no each-way).
18+. New UK customers. Min £20 deposit (debit card or bank transfer). Qualifying bet £20 at min odds 3.0 (2/1). £50 in free bets over 48 hours, min 5 legs, expire in 5 days. T&Cs apply.
2. bet365 — one of the UK’s best new customer offer
★★★★★ 5.0 / 5
Few names carry the weight of bet365, and for once the reputation is earned. It remains the benchmark for live betting and market depth — whether you’re on the Premier League, the Champions League, a Saturday handicap at Haydock, Formula 1 or the UFC, you’ll struggle to find a deeper card anywhere in the UK. New customers can typically claim £30 in Bet Credits from a £10 qualifying bet (the exact promotion can vary at sign-up), with a low £5 minimum deposit making it one of the more accessible premium offers going.
Where bet365 pulls ahead is everything around the bet: Bet Builder, Cash Out, early payout on football, price boosts, Best Odds Guaranteed on racing, and free live streaming of UK and Irish meetings to funded accounts. The app is, year after year, among the best in the business.
Who it’s for: football fans and regular all-sport bettors who want one account that does everything well.
Claim £30 at bet365 → · Code: 365GMBLR
18+. New customers only. Min deposit £5. Bet Credits paid on settlement of qualifying bets at min odds 1/5 (1.20); returns exclude the Bet Credits stake. T&Cs apply.
3. Betfred — the one for horse racing promotion
★★★★☆ 4.5 / 5
A familiar name on every British racecourse since 1967, Betfred still puts racing front and centre — and its Bet £10, Get £50 welcome package is one of the most generous on this list, landing as £20 in sports free bets, £20 in acca free bets and 50 free spins. It’s the bookmaker we reach for during the big festivals, thanks to dependable Best Odds Guaranteed, Tote Placepot coverage, extra-place concessions and the Lucky 15/31/63 bonuses that reward multiple-runner punters.
Football bettors aren’t left out either, with regular acca insurance, enhanced odds and Bet Builder offers running through the Premier League season.
Who it’s for: horse racing fans who want festival concessions and the biggest stake-to-bonus ratio here.
Claim £50 at Betfred → · Code: BETFRED50
18+. New customers only. First bet £10+ at min odds Evens (2.0) within 7 days. Returns as £20 in-play + £20 acca + 50 free spins. 7-day expiry. T&Cs apply.
4. QuinnBet — excellent value for racing bettors
★★★★☆ 4.5 / 5
QuinnBet has won a loyal following among UK racing punters on the strength of competitive prices and a welcome offer built around a safety net rather than a free-bet lottery. Bet at least £10 across three or more selections at odds of 2.0+, and QuinnBet refunds 50% of your first-day losses as a free bet, up to £25 — so a losing start to your week comes back, in part, to bet again.
Racing is the strong suit, with regular Best Odds Guaranteed, extra places and daily offers, but the sportsbook also covers football, tennis, golf, darts and the rest.
Who it’s for: racing bettors who prefer a loss refund to a qualifying-bet free bet.
18+. New UK customers. Min 3 bets of £10+ on separate events at odds 2.0+. 50% of first-day net losses refunded as a free bet up to £25, valid 7 days. T&Cs apply.
5. Betsuna — the newest betting site in the UK on the list
★★★★☆ 4.0 / 5
Launched in May 2026 and run by ProgressPlay (UKGC licence 39335), Betsuna is the freshest face here — a combined sportsbook, casino and bingo site on a single wallet. Its sports welcome offer is among the most generous around: Bet £10, Get £50 in Free Bets. Coverage already spans football, horse racing, tennis, cricket, rugby, golf and more, and the racing markets are deeper than you’d expect from a brand this new.
It’s worth being clear-eyed about a newcomer: there’s no dedicated app yet (the site is mobile-optimised instead), and Betsuna doesn’t have the festival heritage of a Betfred. But the licence is solid, the welcome value is real, and it’s one to watch.
Who it’s for: bettors who like trying a newer brand and want a high-value sign-up.
18+. New UK customers. Bet £10 to receive £50 in free bets. ProgressPlay Limited, UKGC #39335. T&Cs apply.

Free bets & betting offers — FAQs
Which bookmaker has the best welcome offer? For overall value we rate SBK highest, thanks to consistently sharp odds and a clean £40 free-bet sign-up — bearing in mind those free bets must be used on five-leg-plus accumulators. If you simply want the biggest headline figure, Betfred and Betsuna both offer £50.
Are free bets really free? Not quite. You’ll almost always need to place a qualifying real-money bet first, and free bets pay out the winnings only — the free-bet stake isn’t returned. They also carry expiry dates and minimum-odds conditions, so read the terms before you claim.
Can I claim more than one betting offer? Yes. Each UKGC-licensed bookmaker runs its own welcome offer, usually one per household, so you can legally hold accounts with several operators and claim each. Many bettors do exactly that to access Best Odds Guaranteed and extra places across different sites.
Which bookmaker is best for horse racing? Betfred and QuinnBet are our two favourites for UK racing, thanks to regular extra places, Best Odds Guaranteed and racing-specific promotions throughout the calendar.
Are UK betting sites safe? Provided they’re licensed by the UK Gambling Commission, yes. A UKGC licence means segregated customer funds, fair-play auditing, dispute resolution and responsible-gambling tools including deposit limits, time-outs and self-exclusion via GAMSTOP. Every bookmaker in this guide holds one.
