SBK is a modern mobile-only betting app launched in 2019 by the team behind the Smarkets betting exchange. It promises to “rewrite the sportsbook” by combining a traditional sportsbook interface with exchange-quality odds. In this in-depth review, we cover SBK’s £40 free bet welcome offer, app features, odds, and how it stacks up against competitors. Read on to learn what makes SBK unique, its pros and cons, and whether it lives up to the hype for UK punters.
SBK New Customer Offer: Bet £20 Get £40 In Free Bets
New UK customers at SBK can claim a “Bet £20 Get £40 In Free Bets” welcome bonus – one of the most generous offers in the market. Here’s how it works and the key terms:
- Offer Overview: Deposit and place a £20 bet at minimum odds of 2.0 (evens), and SBK will credit you with £40 in free bets within 48 hours of your qualifying bet settling.
- Wagering Requirements: There is no further wagering requirement on any winnings from the free bets – you keep what you win (minus the free stake) as cash. However, free bet tokens themselves expire 7 days after being credited if not used.

Also, you must not already have an account with SBK or Smarkets (one welcome offer per person/household).

SBK & Smarkets: Background and Brand Overview
SBK is operated by Smarkets (Malta) Ltd. It uses Smarkets’ exchange technology to deliver sharp odds through a traditional sportsbook interface. You simply back selections – no need to learn exchange mechanics – but benefit from better odds thanks to low margins.
SBK is purely sports-focused with no casino or poker. It’s regulated by the UK Gambling Commission and is only available via mobile app – there’s no desktop betting. If you prefer desktop betting, consider Smarkets directly instead.
Odds and Markets – Exchange-Level Odds That Often Beat the Rest
SBK’s biggest strength is odds value. Prices are powered by the Smarkets exchange, meaning they’re often better than high-street competitors. The app highlights top prices, flagging when SBK beats other bookies.
Market Coverage
SBK offers over 20 sports including football, racing, tennis, cricket, basketball, golf, and niche categories like esports and politics. Football and racing are particularly strong. You’ll find deep coverage for Premier League, Champions League, and global leagues, plus UK and Irish racing.
Bet Builders and Multiples
Football and basketball Bet Builders are available, with options for cards, corners, goalscorers, etc. The interface is clean and intuitive. Multiples can also be built across events.
No Casino
SBK sticks to what it does best – sports. There are no slots, table games, or bingo to distract.
SBK App User Experience and Features
SBK’s mobile app is slick, fast, and clean. It features a minimalist interface that loads quickly and supports one-handed navigation.

Auto Acca
SBK’s Auto Acca tool builds accumulator bets automatically based on your preferences – ideal for weekend football.
Fresh Legs Promo

Live Betting and Streaming
SBK offers strong live betting options with responsive odds and stats. Football, tennis, and basketball are all well supported.
Streaming

Verdict – Is SBK Worth It?
If you bet primarily on sports via mobile and care about getting the best odds, SBK is a fantastic choice. It’s particularly strong for football and racing fans who like Bet Builders and accumulators. The £30 welcome offer is one of the best in the UK, and the Fresh Legs promo shows real innovation.
It’s less suited to punters who enjoy casino games, lots of small promos, or desktop betting. But for a clean, value-driven sportsbook built for today’s bettor, SBK gets a big thumbs up.
Overall, a sharp app for sharp bettors.
