Covers Expert Analysis

"The William Hill sign-up bonus is a larger amount than typically available at UK sites, which means you have more chances to strike a win. For me, the key advantage lies in the flexibility to use the free bets across different sports. Some sites lock their free bet offers on football or horse racing, so if you're looking for more freedom, William Hill is a great choice."

All William Hill sign up offers for UK players

The industry standard welcome bonus is only £30 in free bets, so the extra £10 available at William Hill means you’ll be starting off with one of the best sportsbook promos available to UK players. To claim, you simply need to type in the code G40 when signing up, place a bet of £10 or more, and you’ll get £40 in free bets regardless of the outcome of that initial bet.

Sports you can bet on with William Hill

William Hill customer support for new players

If you have any trouble claiming the William Hill promo code offer, please know that customer service is here to help. The live chat option is the fastest route to finding a solution, and the agents seem knowledgeable about betting, account, and promotional queries.

That said, availability has some limitations: while live chat is available 24/7, email and phone support are more restricted. When I checked, agents were available for calls from 8am-10pm from Monday to Sunday, so I imagine most players would find this workable.

Sign up offer payment methods at William Hill

Part of claiming the new customer offer at William Hill involves placing a bet with your own money. That means you'll first have to deposit. 

William Hill supports the most popular UK payment methods, including debit cards, e-wallets, and bank transfers, offering a mix of instant deposits and reasonably fast withdrawals.

Under UK Gambling Commission guidance, credit cards are no longer accepted for gambling deposits in the UK.

William Hill Casino sign up offer and bonuses

Most people associate William Hill with sports betting and its status as one of the best horse racing betting sites, but it also offers a strong casino platform and bonuses. If you’d rather play slots, cards, or dice games, here are the promotions you’ll need to know about:

🎰 William Hill Casino welcome offer: Stake £10 and get 200 free spins

The William Hill Casino welcome bonus is similar to its sports betting bonus; a bet-and-get offer. You bet £10 and get 200 free spins to use on selected slots when using the code G40 at the time of registration.

Most casino bonuses are 100% deposit matches, so this sign up offer will appeal to those who prefer smaller deposits. Each free spin is valued at £0.10, for a total bonus value of £20.

🎉 Bonus Drop Boost

The Bonus Drop Boost is a free-to-play game that runs from Saturday to Thursday. You can win cash, free spins, or bonuses simply by logging in and playing each day. It's a tipping-point style game, where you drop a coin into the machine and whichever slot the coin lands in matches up with a prize.

🙌 V Play

With V Play, you can reveal cash rewards when playing your favourite casino games at William Hill. The V Play promotion applies to all slots and table games that display the V Play logo. Whilst using your real money balance on these games, you may randomly be offered a chance to spin the V Play Wheel, where you can win bonuses or cash prizes.

How we rate bonus offers at Covers

Covers uses its BetSmart Rating system to evaluate top bookies across several key areas that matter most to bettors. Instead of focusing solely on promotions, it assesses overall value, including payout speed, security, platform features, and customer support.

Covers Verdict

William Hill is one of the most established names in the UK betting market and is considered by many to be one of the best bookmakers. It has promotions to match its glowing reputation.

With the William Hill sign up offer, you can bet a relatively low stake of £10 and receive £40 back in free bets. Unlike at other bookmakers, these free bets can be used across almost all sports and betting markets. Couple that with low minimum odds and no wagering requirements, and it’s easy to see why the offer is consistently ranked among the best available.

Simply click through a link on this page and use code G40 when signing up today to claim the offer.
