SBK, as they say, are ‘rewriting the sportsbook’, and many have taken to their unique betting coverage of sports. Before you take a plunge into their premier betting exchange, you’d be wise to make the most of the generous welcome offer SBK boast. We’ll detail everything there is to know about the promotion in this guide.
What Is the SBK Sign-up Offer?
To qualify for SBK’s new customer offer, you must first deposit at least £20 into your account after signing up. This promotion is a straightforward Bet £20 Get £50 in Free Bets offer, with the free bets split as follows:
-
£5 Bet Builder and £5 Multiple on settlement of your qualifying bet.
-
A £10 Free Bet token and £5 Bet Builder token after 24 hours.
-
A further £10 Free Bet token, £5 Bet Builder token and two £5 Multiple tokens after 48 hours.
Note that free bets require a minimum of three legs.
Qualifying bets must be worth at least £20 and placed at minimum odds of 3.0 (2/1). Single bets, Bet Builders and Multiples can all qualify, provided they meet the minimum stake and odds requirements. While the distribution of your free bets is spread out over two days, these freebies can be used across a range of SBK sports markets.
The offer gives new customers the chance to wager on a number of sports and, while there are a few restrictions in there, the £50 reward still compares well with offers from other leading UK bookmakers.
Users can only qualify for this promotion if they make their first deposit by card or instant bank transfer. Those depositing via Skrill, NETELLER, Revolut, PayPal or a virtual or prepaid card will not qualify.
Also, only residents of the UK who are new to both SBK and Smarkets Exchange are eligible for this promotion.

ThePuntersPage Final Say
SBK’s Bet £20 Get £50 in Free Bets new customer offer provides users with a strong bonus in return for their initial qualifying stake.
The bookie offer punters 250% of their initial stake in free bets, which still compares well with many offers in the industry. A £20 minimum stake is a larger commitment than some rival promotions require, but £50 in free bets is one of the more generous headline rewards currently available.
Other operators, such as Coral and bet365, offer greater freedom in terms of qualifying odds, initial stake and how the free bets can be used. However, this is still a good-value offer from one of the leading online bookies in the UK, particularly for punters who enjoy Bet Builders and Multiples.
