Why do bettors like William Hill?

As you may have read in my William Hill review, this betting site has definitely gained its place as one of the most popular choices for UK bettors, and for good reason. Bettors appreciated the extensive range of betting markets available from football to global sports like tennis, basketball, and even niche markets like esports. Plus, their live betting feature is absolutely top-notch, allowing you to place bets while the action unfolds. I really like that William Hill consistently delivers reliable odds and promotions, whether it's a seasonal bonus, an accumulator boost, or other offers, there’s always something new going on.

Top 3 William Hill sister sites

I’ve reviewed the best betting sites in the UK and rounded up my top three sites like William Hill. Whether you’re looking for a solid sportsbook, great casino games, or a mix of both, these sites offer similar features to William Hill.

BetMGM - get started with an excellent welcome deal

If you’re in the UK and you’ve heard of betMGM, you might think it only caters to the US markets but I can tell you that it’s more than just an American sportsbook. BetMGM offers a comprehensive range of betting options, not just for US-based events but for global events too. Whether you’re a fan of football, tennis, rugby, cricket or even darts, you’ll find something here to suit you.

BetMGM is renowned for its sleek easy-to-navigate platform, and it’s just as good on mobile too. The BetMGM app offers a smooth experience whether you’re betting on a live football match or checking odds while waiting for the train. I personally love the range of solid live betting options that this site has to offer. Whether on the website or in the app, I could track my bets, place in-play wagers and follow along with the live odds without any hassle. It’s not the most UK-centric site out there, but it’s been getting much better with promotions aimed at UK bettors, which I’ve been really happy to see.

The casino section is actually pretty decent too with a good mix of slots and table games, for those times that I fancy a break from sports betting. BetMGM also offers 24/7 customer support for peace of mind, including a live chat with fairly quick response time and a detailed FAQ section. Admittedly, the UK bonuses aren’t as competitive as some of our other platforms, but let’s take a look at what’s on offer right now.

BetMGM offers both a sportsbook and an online casino, and both come with separate bonus offers. For casino fans, you can grab 10 free spins when you play your first £10. To be honest, it doesn’t get much more simple than that. All you need to do is deposit £10 within seven days of signing up, wagering it once on any casino game - keep in mind that this is excluding live casino and table games - and boom, you’ll get 100 free spins to use on Big Bass Splash. The free spins are worth 10p each, and you’ve got three days to use them. Not bad at all!

For those who prefer sports betting, the bet £10, get £40 in free bets offer is a solid deal. Simply place a qualifying bet at odds of 1/1 or greater, and you’ll get £40 in free bets, broken down into: £10 for football, £10 for horse racing and £20 for Bet Builders. I think this is quite a nice way to grab some free bets to have a go at betting on different markets. Just make sure that you use it within seven days, otherwise your free bets will expire.

📌 What makes BetMGM such a good William hill sister site?
  • Both sites focus on offering a great all-round user experience, especially in the sports sector. While William Hill is obviously more UK focused, BetMGM brings a wealth of international options to the table, including major US leagues, so if you’re a William Hill fan who enjoys variety, BetMGM may be right up your alley.
  • BetMGM is super clean and easy to navigate and their live betting options are top tier, just like William Hill. You can expect a similar betting journey too with easy deposits, a wide range of sports, and reliable customer support. And while William Hill has its UK charm, BetMGM offers a modern touch, which may be exactly what you’re looking for.

bwin - fantastic coverage of sports and betting markets

Now, bwin, this one’s a bit of a hidden gem for UK bettors, especially if you love European sports - and let’s face it, don’t we all? I first came across it when I was browsing for William Hill sister sites that covered UK football leagues, and I’m very glad I did. They’ve got the Premier League, Championship League and some of the lower leagues too, plus a pretty extensive range of international markets. If you’re into football, like me, then this is a massive win. The living betting options are on point too, making it super easy to make in-game bets.

I really like when a site is easy to use as I really don’t have time to search through pages and pages to find the game I’m after. It’s simple and navigating through the various tabs is a breeze. Their mobile app makes betting on the go super smooth too, and I’m rarely left frustrated trying to place a quick bet when I’m out and about. Sure, their casino section is a little bit smaller than William Hill, but they’ve got enough slots and table games to keep most bettors entertained that are just looking for a change of pace. bwin also has decent customer service, although it’s not available 24/7, but they do have a live chat during business hours for quick responses.

The only downside I could find is that the welcome offer isn’t as good as some of the betting sites that are more established in the UK. But it's still worth checking out as it's straightforward and a nice way to get started. New bettors can register and get a £20 Backup Bet. Here’s how it works:

  1. Click our links to head over to bwin and start the registration process.
  2. Fill in the requested personal details and hit submit.
  3. Place a sports bet (3+ selections) with a minimum of £10 up to £20 with combined odds of 3.0 or greater. Just keep in mind that you can’t include horse racing in your bet when claiming this offer.
  4. If your bet wins, you’ll take home the winnings. But if your bet loses, then you’ll receive your £20 bonus bet back as a free football bet. This bonus bet will be valid for seven days.

It’s an excellent offer for any bettors who like to place multiple selections, and the fact that it covers football (my personal favorite) is a bonus. You get a safety net with the backup bet.

⚡ What makes Bwin a site like William Hill?

If you’re used to betting on William Hill, then you might find a lot to love about bwin. Both of them have a long history in sports betting, and the user experience is pretty similar. For example, navigating bwin is a breeze - just like William Hill. Whether you’re looking to bet on football, tennis, or horse racing, you’ll find all your go to options with ease.

The live betting also stacks up well to William Hill, offering that same excitement of placing those in-game bets. And let’s not forget the promotions either - while clearly not as big as what you’d find at William Hill, bwin offers a decent first bet safety net to make signing up even more rewarding. The real draw of bwin though is of course the European focus as this site’s coverage of UK and European leagues is fantastic.

Betano - modern betting site with great bonus offers

Alright, let’s talk about Betano - this one’s relatively new in the UK market so I had to do a bit of a deep dive, but I think it’s definitely got some potential. They cover a huge variety of sports that includes the big ones like football but also rugby, tennis and even some virtual sports thrown in there as well. I’m always looking for new markets to explore and Betano doesn’t disappoint there.

The site itself is easy to navigate and the mobile app works like a charm. I’ve had no issues with placing bets on the go, and the live betting options are actually really good too. I especially like how quickly the odds update in real-time, so I’m never left out of the loop. Betano also has a growing list of UK-specific promotions too so they’re starting to offer some pretty solid options. Their casino platform is still expanding, but it’s got a few slots and games for users to explore if they so choose, including popular titles like Big Bass Splash. Betano has decent customer support, with live chat which is fantastic, but you may find that the email support is slower than competitors.

Betano’s welcome offers are pretty straightforward, giving new players a solid start with two main offers to choose from. Let’s take a look at all betting bonuses available from this platform:

  • Football welcome offer - bet £10, get £30. If you’re new to Betano and love a good football bet then this one’s for you. Simply opt in, bet £10 on any football market with odds of 1/1 or greater within three days of signing up and you’ll get 2 free £10 bets on selected football markets and 1 free £5 for football, plus a £5 slot bonus on Big Bass Splash. It’s important to keep in mind though that the casino bonus bet comes with a 30x wagering requirements before any winnings can be withdrawn.
  • Sports welcome offer - bet £10, get £10. With this offer, you can opt in and bet £10 on any sports with odds greater than 1/1 within three days of signing up and receive a free £10 bet, just remember that this expires in five days.

📎 Why should bettors who like William Hill choose Betano?

I think what makes Betano so appealing to William Hill fans is the versatility. Like William Hill, Betano offers a great selection of both sports betting and some casino games too. The sports selection in particular really stands out, especially the football markets, making it great for any UK football fan. And just like William Hill, they’ve got a good mix of live betting options, so you can stay on top of the action as it unfolds. They don’t have quite the global coverage of William Hill, but it’s a solid alternative for UK bettors.

Comparing William Hill sister site welcome offers

BetMGM offers the biggest welcome offer, while bwin might appeal more to football fans. Betano has two welcome offers, giving players a choice between the football bet and general sports bet.

Final thoughts on William Hill sister sites

After comparing betMGM, bwin, and Betano, it’s clear that each of these William Hill sister sites brings something special to the table. Whether you’re after the massive variety that BetMGM offers, the football-focused features of bwin, or the flexibility of Betano’s sports and casino options, there’s something for everyone. As always, I’d recommend considering what’s most important to you - whether it's the welcome offers, the specific leagues you want to bet on, or the overall user experience - and then choosing the site that best suits your needs. Ultimately, all of these sites have one thing in common and that’s that they’re fantastic William Hill sister sites, keeping you in the game with great odds and exciting promotions.
