William Hill gives new customers £30 in free bets after a £10 qualifying sports bet at odds of 1.50 or greater. Use promo code R30 if prompted.
William Hill, Smarkets, and any other operator mentioned here are independent third parties. Their live prices, promotion terms, eligibility rules, payment-method restrictions, and settlement decisions always prevail over our summary, so verify them before you deposit or place a bet.
Prefer to see the full flow before you place anything? This walkthrough uses the same William Hill offer and shows the bookmaker side, the oddsmatcher step, and the calculator together.
Switch William Hill and Smarkets to decimal odds in account settings. The calculator and oddsmatcher do not match fractional odds.
Independent guide only. We are not acting for William Hill or any exchange, and you must follow each operator's own rules when using this walkthrough.
Enough to cover your qualifying stake in your William Hill account - typically £10–£25 depending on the offer.
Around the same amount in your Smarkets account for the lay side. The calculator will give you the exact figure.
In both your bookmaker account and exchange account, switch the odds display from fractional (e.g. 5/2) to decimal (e.g. 3.50). The calculator only accepts decimal - mixing formats is the most common beginner mistake. Look for a toggle in account settings or somewhere on the betting slip.
Open the calculator in another tab — never mentally calculate a stake. The numbers are precise.
Don't start an offer if you're interrupted, tired, or in a rush. Mistakes compound when you're distracted.
Odds shift in seconds. Before you confirm each bet, check that the odds in your bookmaker and exchange still match what the calculator was given. If they have moved more than 0.05, re-enter the new odds into the calculator first.
A mistake on a qualifying bet typically costs £2–£10. A mistake on the free-bet conversion can cost the full free-bet value. Running through these takes 30 seconds.
Read each step in full before placing the bet. The calculator gives you the exact numbers - never improvise the stake. Mistakes on a qualifying bet typically cost a few pounds; mistakes on a free bet can cost the whole conversion.
Open the site, complete the registration with your real details. No VPN. You may be asked for ID verification.
Make sure the deposit method is a UK debit card — Skrill, Neteller, and PayPal deposits exclude you from the offer.
William Hill is strict about deposit methods. Double-check the terms before depositing.
The Live Oddsmatcher shows back/lay matches; Smarkets is where you place the lay bet. Sign up to Smarkets if you haven’t (free, instant).
In the Live Oddsmatcher sidebar, set Bet phase = Qualifying, Bookmaker = William Hill. The board now shows William Hill matches with low odds (1.5–4.0) — ideal for the qualifying bet. Sort by rating; pick the top match.
Click the top match to expand the inline calculator. The back/lay odds are pre-filled. Enter Back stake £10 — the calculator shows the exact lay stake.
On William Hill, click the same outcome from the oddsmatcher. Enter exactly £10. Confirm.
On Smarkets, click the BLUE sell button next to the same outcome. Enter the lay stake from the calculator. Confirm.
BLUE sell button, not the GREEN back button. Selling is what cancels out your risk.
Once the qualifying bet settles, you receive 3× £10 free bets. They cannot be combined into a single £30 bet — each must be used separately.
Back in the Live Oddsmatcher, change Bet phase to Free bet (keep Bookmaker = William Hill). Pick a match with back odds 5.00+ if available — higher odds extract more cash. Click the row to expand the inline calculator, switch to "Free bet (SNR)" mode, enter Stake £10.
On William Hill, tick "Use Free Bet" BEFORE confirming. Place the £10 free bet on your chosen outcome. Then place the corresponding sell bet at Smarkets.
Different match (same Live Oddsmatcher filters), same flow: click row → inline calc → £10 free bet at William Hill, lay at Smarkets. Repeat until all three £10 free bets are converted.
Total profit usually £20–£24 spread across both accounts. Withdraw to your debit card from each.
William Hill requires 1.50+ on the qualifying bet - higher than Bet365's 1.20 threshold. A bet at 1.40 won't qualify, even though it would have qualified at Bet365. Always check the specific bookmaker's threshold.
You receive 3× £10 free bets, not a single £30 free bet. They must be used separately, each on its own bet slip. Staking £30 on one bet uses only £10 of free-bet credit plus £20 of your own money.
Skrill, Neteller, PayPal, and other e-wallets are excluded from the William Hill welcome offer. UK debit card is the only safe deposit method.
The free bets expire after the window shown in your William Hill account. Use them promptly rather than saving one for later - the clock keeps ticking on every free bet once credited.
Higher odds = more profit on a free bet, but very high odds (10.0+) have wide back-lay spreads on Smarkets - wide enough to sometimes wipe out the profit. The 5.0–7.0 range is the sweet spot for SNR free bets.
Most UK bookmakers allow withdrawal back to the original debit card. Withdrawals typically clear in 1–3 business days.
