How Does the SBK Sign-Up Offer Work?
The SBK Bet £10 Get £40 offer is a deposit-and-bet welcome bonus. Make a £10 first deposit by debit card or bank transfer, then place a single £10 bet at minimum odds of 3.0 (2/1). Both Bet Builders and Multiples qualify as long as the stake is £10 or more; each-way bets under £10 total and cashed-out bets don’t count. Once your qualifying bet settles, SBK release the £40 in free bet tokens across three consecutive days rather than all at once. No promo code is required, but you must register through the offer link for the bonus to attach to your account.
What’s Included in the £40?
The SBK £40 is credited in tranches over three days, made up of Bet Builder, Football Bet Builder and Horse Racing Multiple tokens:
When
You Receive
On settlement
£5 Football Bet Builder + £5 Horse Racing Multiple
After 24 hours
£5 Bet Builder + £5 Football Bet Builder + £5 Horse Racing Multiple
After 48 hours
2 × £5 Multiple + £5 Bet Builder
That’s £40 in total in £5 tokens. The key condition: every SBK token requires a minimum of 4 legs, so they’re built for Bet Builders and accumulators — across football and horse racing — rather than singles.
What Is the Catch With the SBK Free Bets?
There are three honest catches with the SBK £40 worth knowing before you claim. First, the qualifying odds are high — your £10 bet must be at minimum odds of 3.0 (2/1), steeper than the evens or 1.5 most rivals ask. Second, the tokens need a minimum of 4 legs and come in fixed £5 denominations, so they’re only usable on Bet Builders or multiples, not singles, and not on full cover bets. Third, the winnings are paid but the stake isn’t returned (a £5 token at 3/1 returns £15, not £20), tokens expire 5 days after credit, and excluded deposit methods (Skrill, Neteller, Revolut, PayPal and virtual or prepaid cards, including virtual Monzo) don’t qualify. Note too that this £40 is a limited-time boost — available to new customers signing up until 17:00 BST on 7 October 2026.
How Do You Claim the SBK Sign-Up Offer?
To claim the SBK Bet £10 Get £40 offer, follow these four steps:
Register through the offer link — no promo code needed, but you must sign up via the link for the bonus to attach.
Deposit £10 by debit card or bank transfer (Skrill, Neteller, Revolut, PayPal and virtual or prepaid cards, including virtual Monzo, are excluded).
Place a £10 bet at minimum odds of 3.0 (2/1) — a Bet Builder or Multiple both qualify, and cashed-out bets don’t count.
Get £40 in tokens — credited across three consecutive days once your qualifying bet settles. Use each token on a 4+ leg selection within 5 days.

In our test, the SBK £40 arrived exactly as advertised — in £5 Bet Builder and Horse Racing Multiple tokens across three days once the qualifying bet settled. The 4-leg requirement means it rewards punters who genuinely build multiples, so plan to use the tokens on Bet Builders rather than expecting flexible free bets.

What Is SBK?
SBK is the sportsbook arm of the Smarkets betting exchange, built around exchange-powered odds and a strong Bet Builder product. It offers deep football coverage — Premier League, EFL and European competitions — alongside horse racing and the other major sports, with pricing that tends to be sharper than the traditional bookmakers because it draws on exchange liquidity. The app is clean and fast, and the Bet Builder is its standout feature, which is exactly what the Bet £10 Get £40 welcome offer is designed around.
Our Verdict on the SBK Sign-Up Offer
SBK delivers a big headline at Bet £10 Get £40, and the value is genuine if you’re a Bet Builder or accumulator punter — the tokens span football and horse racing, and SBK’s exchange-powered pricing is among the sharpest around. The honest catches are the higher qualifying odds of 3.0 (2/1), the 4-leg minimum on every token, and the fact that this £40 is a limited-time boost. Use it as intended — on genuine multiples over the 5-day window — and it’s one of the stronger offers for combination bettors. A strong sign-up from a sharp, well-backed operator.
