With 33 different sports sections and tens of thousands of monthly markets, the reason why many punters choose this platform is abundantly clear. Plus, if you fancy a non-sports bet, the Politics section offers incredibly interesting selections with an in-depth explanation of why they consider politics, both domestic and international, a fruitful area for gambling. It turns out there are more reasons many punters choose this platform: the odds are among the best in the UK, and the Top Price Guarantee is standard for football betting offers. Live betting also has a Cash Out option, and in-game stats will make your live betting an even smoother affair. William Hill customer support is offered in a wide variety of languages, and they’re available 24/7.

Free Bets

UK customers can reach them over the phone as well, and they’re also reachable on public holidays. Plus, the FAQ page is pretty exhaustive when it comes to common issues. Since William Hill is international, the number of payment options is absolutely astounding. They accept debit cards, eWallets, Apple Pay, cash transfers and online banking, plus vouchers and prepaid cards. However, the William Hill sign up offer is unavailable to those using PayPal, Neosurf, Paysafe, NETELLER, Skrill, ecoPayz, Kalibra, or Postepay—in other words, any of the eWallets and prepaid vouchers bet sports betting online free on offer.

Expiry Period

Although they have minimum withdrawal limits, if your total balance is below that limit, you will still be able to withdraw it all (but not partially). You can also set your own deposit limits if you want to.

888sports is one of the best platforms when it comes to bonuses, promotions, and various offers, especially for punters who become the platform’s regulars. Compared to the rest, the 888sport sign up offer is actually on the small side—you place your first qualifying bet of at least £10 (£20 for Each Way bets), and you get three £10 free bets for a total of £30 (not available for users of PayPal, Muchbetter, Paysafe, Neteller, and Skrill). One promotion that’s available on all sports is in case you win at 4/1 odds or bigger with a stake of at least £10, which gives you a £5 free bet. A free predictor game lets you pick the win-draw-win results of eight games in total, letting you win up to £8,000 in cash if you get them all right (if you fail, you’ll get a £1 free bet for each pair you guessed right). Keep in mind that every 888sport free bet you may get expires after seven days, so there’s no use hoarding them.

888sport offers around 30 sport varieties including esports and virtual sports, but their markets are rather UK- and Ireland-centric. This may not be a bad thing if that’s what you’re interested in, but if you’d like to try your hand at some foreign markets, this may not be the place for you. The platform offers your usual betting types, along with a Bet Builder for unique odds, which lets you combine markets within the same event, both pre-match and in-play. However, these are far from boring, especially when combined with constantly running 888sport promotions, which means you can get pretty creative. The FAQ section is available and extremely helpful, covering questions such as technical issues, what the registration process entails, and sports rules, odds converters, and bet builders.

In-Play Bonus Bet Offers

888sport offers a huge variety of payment methods, including cards, prepaid vouchers, eWallets, and bank transfers. However, their betting sign up offers are contingent on you only using debit cards at least for the first deposit that qualifies you for their welcome bonus, so if those are important to you, make sure you read the fine print carefully. Withdrawals are done to the same method used for depositing. If that’s not possible, expect to have to provide more identification before you can get your money. Decent sign up offer, but with restrictions Platform rewards regular punting, as well as winning at high odds The William Hill free bet doesn’t expire as quickly as on other platforms Decent bonuses for a wider range of sports than most William Hill is one of the oldest and most reputable bookmakers on the UK market, established in 1934 at a time when gambling was illegal. Unibet offers 34 sports markets, including lacrosse, pesäpallo, and chess. On your left-hand side of the screen, you can see the number of bets available for any category at any given moment, making it easy to check where everything is going on.

Everything else is eclipsed by football, however, as it had more than 33,000 markets at the time of writing.

Sportsbook	Bonus Amount Example	Rollover Requirement	Time Limit	Sport Restrictions
Barstool Sportsbook	$500 bonus bets	1x playthrough	30 days	Any sport
Unibet	$100 risk-free bet	5x playthrough	14 days	Major sports only

However, sports and racing are considered two separate categories, so don’t be confused if you can’t immediately find the latter.

Different Types of Bookmaker Offers Explained

The company now operates worldwide and has close to 1,600 licensed betting offices all over the UK and 2,300 betting shops, employing around 14,000 people total. William Hill offers everything your gambling heart might want, including a sportsbook and a casino, with a reputation of Britain’s favourite bookmaker to boot. They also sponsor the annual William Hill Sports Book of the Year award which is dedicated to excellence in sports writing. The William Hill website is pretty easy to navigate, although sports betting seems to disappear between all the other games. The interface looks high-end, in line with their whole presentation, and you can even choose the odds format you prefer.

🖥️ Which sites give free bets?

A quick button takes you to all live events, while a Search bar just below that can help you locate the exact markets you want to bet on. William Hill reviews show that the apps, both iOS and Android, are also held in high esteem among their users, but for punters who don’t want to commit to downloading an app, their mobile site works just as well. When it comes to offers and bonuses, the bookie’s reputation still holds up under scrutiny. For example, new customers who bet at least £10 on odds 1/2 or greater will receive £30 in free bets, in two £15 denominations, to be used within 30 days (which is longer than many platforms offer). To claim this offer, you’ll need to use the William Hill promo code during sign up.

William Hill also offers different bet betting apps with sign up bonus uk bonuses and promotions on a wider range of sports than many others. This means that, aside from football and horse racing, fans of golf, cricket, and tennis are also likely to find something to suit their needs. UK and Irish horse and greyhound races also have best odds guaranteed, and the bookie also offers great bet boosts for accas, which include one bet boost per customer per day on accas with three or more selections, excluding horse and greyhound racing. Aside from general offers and bonuses, William Hill promotions often include current events like derbies, so make sure you’re keeping your eye out for anything you may like. William Hill’s middle name is variety, so you’re likely to find anything and everything here. With the number of available markets, we’d be hard-pressed to find something Unibet doesn’t support.

Sportsbook	Bonus Type	Offer	Minimum Deposit
BetMGM	Risk-Free Bet	Up to $1,500	$10
FanDuel	No Sweat First Bet	Up to $1,000	$10
DraftKings	Deposit Match	20% up to $1,000	$5
Caesars	First Bet Insurance	Up to $1,000	$10

This is especially true when it comes to football: any match insights you can imagine have their odds already set, along with Unibet promotions for major events, and you can bet on even the most advanced statistics like the number of offsides or fouls committed.

Sportsbook	Bonus for Referrer	Bonus for New Friend	Friend's Requirement
Caesars	$100 bonus bet	$100 first bet insurance	Bet $50

They also sponsor a large number of sports clubs: in England, it’s the football clubs Aston Villa, Preston North End, and Middlesbrough and the Warwickshire County Cricket Club. Unibet reviews show that customers generally trust the bookie and hold it in high esteem. The Unibet website first lets you choose among a number of different locations from all over the world, and if you can’t find your own there, you get to choose a general website in English, Spanish, French, and Russian. Of course, the UK has its own website with localised offers, focusing mostly on football and horse racing. Their sports app is separate from the casino and poker apps, and is available on both iOS and Android.

Step 2: Register your account

The Unibet sign up offer is designed to take the pressure off newcomers: if your first sports bet (minimum £10 deposit and £1 bet, minimum odds 2/5) loses, you get your money back, up to £40, along with a £10 casino bonus. The same offer is available for racing, but they’re claimed separately, and one cancels out the other. This is due to racing (greyhound, horses, and harness racing) being separate from other sports on the Unibet platform, and the popularity of racing in the UK proves that this is a good thing for many users. Their other promotions are pretty extensive and cover football, horse racing, tennis, and major US Sports. One of the best Unibet promotions currently available is the Refer a Friend bonus, where you can get up to £250 for inviting five of your friends, and each subsequent friend who accepts the invitation nets you an increasing amount of money. Even if you can’t resolve your issue that way, their customer support agents are very kind, prompt, and available in a number of languages.
