William Hill Promo Code April 2026: Use G40 to get £40 in Free Bets

The latest William Hill promo code is G40, which will unlock £40 in free bets when you stake £10. To claim it, you’ll have to click through a link on this page, register, and stake £10 on sports at odds of 1/2 or higher.

With a packed sporting schedule this week, there has never been a better time to read up on the William Hill bonus code and claim it for yourself:

The latest welcome offers from William Hill cover several parts of the brand, including the bookmaker, casino, poker, and bingo sections.

New players can claim free bets on sports betting, while the casino and bingo sections regularly feature free spins and promotional game s.

Comparing bookmaker bonuses helps you understand the real value of an offer, not just the headline amount. William Hill has one of the best sign-up offers available in the UK, with low minimum odds and a high cash value.

The William Hill welcome bonus is highly competitive, and I found it to be one of the best welcome offers in the UK market. Bet £10 for £30 in free bets is the most common welcome bonus at British bookies. With a bonus of £40 in free bets, William Hill gives £10 more.

While the same amount is available at Betway, it comes with higher minimum odds, and the free bets are restricted to accas and bet builders. The flexibility of the William Hill promo code can be rivaled only by the bet365 welcome bonus. While bet365 only offers £30 in free bets, it has a lower minimum odds requirement of 1/5. Which bonus is best depends on personal preference.

From my experience, the William Hill sign-up offer is as straightforward as you’ll find in the UK. After registering and entering the William Hill promo code G40, I placed a £10 bet at odds of 1/1.

Once that bet settled, four £10 free bets were credited to my account. These free bets needed to be used within seven days.

Note that virtual sports are excluded from the welcome offer, but everything else is allowed, including entertainment and political betting. 

When I tested the offer, the process of claiming the welcome bonus took just a few minutes. I registered a new account, placed a qualifying bet, and the free bets were credited automatically once the bet settled.

1. Create a William Hill account

Click through a link on this page to head over to William Hill. Register a new account using your personal information. Make sure your address and full name are entered correctly to make the verification process smooth.

2. Enter promo code G40

To opt-in to the Bet £10 Get £40 promotion, enter the William Hill promo code G40 during sign-up.

3. Make a deposit

Deposit at least £10 into your account using an eligible payment method. I used a Visa debit card, and the funds appeared in my account almost instantly.

4. Place a qualifying bet

Make a qualifying bet of £10 at minimum odds of 1/2 or higher. The William Hill sign-up offer lets you bet on any sports market, excluding virtual sports. You can also make your qualifying wager on entertainment or political markets. After you lock in your wager, all you have to do is wait for the bet to settle.

5. Receive free bets

Once your bet has settled, you’ll receive 4 x £10 free bets in your account. You’ll have to use the free bets within seven days.

Before claiming the William Hill welcome bonus, it’s important to understand the key terms.

Below are the most important points, though the full terms and conditions are available on the William Hill website. It’s a good idea to read them in full before claiming the promotion.

• The offer is for new UK customers only.
• Players must enter the promo code G40 when registering.
• The minimum qualifying bet must be £10+ at minimum odds of 1/2.
• £40 in free bets will be paid as 4 × £10 tokens once the bet settles.
• Free bets expire after 7 days if unused.
• Offer applies to bookmaker markets only (virtual sports are excluded).

If you’ve claimed free bets with William Hill, the best strategy is usually to use them on major events taking place this week, where markets are deep, and odds are competitive.

I found William Hill’s sign-up offer to be the best in class for sportsbook sign-up bonuses in the UK right now. Some bookies have tricky terms and conditions that only the more experienced bettors can wrap their heads around. That’s not the case at William Hill.

The balance it strikes between free bet value and player-friendly terms makes it accessible to low-stakes and beginner bettors alike.

• Simplicity 5/5 ⭐: It’s easy to claim the William Hill welcome offer using code G40 using the steps above. Once you’ve unlocked the promotion, a £10 bet on any sport with odds of 1/2+ will allow you to qualify for the bonus.
• Value 5/5 ⭐: The £40 in free bets is a 400% boost on your initial stake, and is £10 more than the industry standard of £30.
• Terms 5/5 ⭐: William Hill offers the flexibility to bet across sports and bet types, and gives low minimum odds of 1/2. Other UK bookies have minimum odds of 1/1 or higher, so the minimum odds featured on William Hill's welcome offer are more favourable.
• Other promotions 4.5/5 ⭐: William Hill has a nice balance of boosted odds promotions and free-to-play rewards for loyal customers. There aren’t as many promotions tailored to more niche sports like rugby, but football and horse racing fans can’t go wrong.
• Overall bonus rating 5/5 ⭐: For me, William Hill’s bonus can only be rivalled by bet365, which offers even lower minimum odds but with a £10 lower value. Given that only the profit is returned from free bets, I’d rather have William Hill’s higher value.

For new customers, the William Hill promo code is G40 for £40 in free bets when you stake £10. Existing customers can't use the welcome offer. However, you will have access to ongoing promotions, including odds boosts, acca offers, and free-to-play games.

These do not require a promo code to claim. Simply head to the 'Offers' section when logged into your account. 

Existing customer promotions at William Hill can provide excellent ongoing value if you take advantage of them regularly.

From football bonuses and accumulator boosts to casino spins and bingo offers, these promotions help extend your betting budget and add extra value. Here’s what’s available:

Here are some of the ongoing promotions existing customers can enjoy at William Hill:

If you’re interested in the casino side of William Hill, new UK players can currently get 200 free spins when they deposit and wager £10 using the BBS200 promo code.

The spins are worth 10p each and apply to Big Bass Splash. Note that the spins expire after 72 hours, and any winnings from them are capped at £30.

William Hill is one of the most established bookmakers in the UK, founded in 1934 and now offering sports betting, casino, poker, and bingo. You also may have come across one of their 1,200 brick-and-mortar betting shops on British high streets.

Since launching online, William Hill has quickly become a heavyweight, rivalled only by bet365. Both betting sites are licensed by the UK Gambling Commission, providing strong regulatory oversight for British customers.

In my experience, the site feels reliable and straightforward to use, with quick account setup, familiar markets on football and racing, and a mobile app that makes placing bets during live matches simple.

Ratings for the William Hill betting app vary across platforms. The mobile betting app is generally well-rated, while independent review sites are more critical of its customer service and withdrawals.

UK customers at William Hill have several secure payment options for deposits and withdrawals, with most transactions processed quickly. The main methods available include:

• Debit cards (Visa and Mastercard)
• PayPal
• Apple Pay (UK only)
• Paysafecard
• Instant bank transfer
• Skrill
• Neteller

I deposited and withdrew via Visa debit card, and found the transactions to be near-instant. Just be aware that William Hill states on their website that it can take 3-5 business days, so be prepared to wait a little longer.

In any case, I’d recommend verifying your account as soon as you register. This will ensure you can move your money with more ease.

Customer support at William Hill is solid, with 24/7 live chat providing the quickest assistance. While many issues can be resolved via the help centre, support is also available through several channels:

• Live chat: Available 24/7 through the website
• Email: customerhelp@williamhill.co.uk
• Phone: Customer helpline available for certain queries (limited hours)
• Socials: Support via X
• Website: Comprehensive help centre and FAQs

I tested the live chat myself at around 3pm on a weekday. Within two minutes, I was talking to a member of staff. After verifying a few details, they were quick to give me the answer.

William Hill offers a wide range of betting markets across the most popular UK sports, particularly football and horse racing. Major matches often feature 100+ markets, including:

• Match result
• Both teams to score
• Over/under goals
• Player goalscorer bets
• Bet builders (custom accumulators)
• In-play betting with live odds updates

Horse racing also includes win, each-way, forecast, and tricast betting across UK and Irish races.

Odds at William Hill are generally competitive but not always the best available. For example, a £20 bet at 1/1 returns £40, slightly higher than 7/8 (£37.50) offered elsewhere.

However, rivals such as bet365 and BetVictor often offer rotating odds boosts which can blow William Hill’s odds out of the water. In my experience, it’s best to have a few different betting accounts and shop around for the top odds. If you’re looking for the latest promo codes at other UK books, we have them here:

William Hill offers betting across 40+ sports, including football, horse racing, tennis, rugby, boxing, cricket, and motorsports.

Football stands out for its huge range of leagues and hundreds of match markets, while horse racing is a core strength thanks to extensive UK and Irish race coverage, live streaming, and regular racing promotions.

There are plenty of niche options too, including politics and entertainment odds. I was particularly impressed with the variety of political odds. Most UK betting sites offer odds on the next Prime Minister and the next election-winning party, but William Hill has additional lines like:

• Party leader exit dates
• Next permanent party leader
• Next London mayor
• Next Democratic and Republican US presidential nominees

One limitation of William Hill is that its odds are not always the most competitive compared with some newer online bookmakers, particularly on niche markets. I’d also like to see more personalised promotions for regular players, as many offers are fairly standard across the industry.

However, beyond minor complaints, William Hill is an industry leader. There aren’t any major limitations in my eyes.

William Hill promotes responsible gambling through tools such as deposit limits, time-outs, and session reminders.

Players can also access support via GamStop, GamCare, Gambling Therapy, and YGAM, helping customers manage play and seek assistance if needed.
