Founded in 1934, William Hill is still thriving with a big welcome bonus, custom bet builder and the biggest max payout in the UK.

How to Open an Account at Online Betting Sites

Over the past months, I've placed bets, tested withdrawals, and compared odds across all 15 bookmakers. Now I’m ready to tell you which sites actually live up to the hype and which ones only look good on paper. Unibet had noticeably more football streams than I expected, and Betway's welcome bonus, while headline-grabbing, is split across four separate bets, which made matched betting a headache. Neither of those things showed up in any competitor review I read beforehand. The 15 bookmakers below earned their spot based on what I actually experienced, not what their marketing says! When you bet just £10, you’ll get 2x £15 free bets, which can be used on 40+ sports. It doesn’t matter if you enjoy football, tennis, boxing or volleyball, you can tune into streams and take advantage of early cash out. I’m also a fan of their #YourOdds Bet Builder that lets you combine goals, cards, corners, and player markets into one custom bet and pays up to 10,000/1.

To save yourself the frustration, make sure you only claim additional bonuses when the company allows it (the table above should help you do that). Most betting sites check your eligibility when you claim a promotion or enter a bonus code. If you've already claimed a welcome offer from another sister betting site in the same network, the bookmaker may reject the bonus, remove any free bets awarded, or inform you that you do not qualify for the promotion. Always check the bonus terms before signing up, as eligibility rules vary between licence holders. A sister betting site, is what we consider a bookmaker, which allows you to bet on sports, that shares a UKCG license with other websites.

For instance, BetVictor, Parimatch and TalkSport Bet are all under license number 39576 and are operated by 'BV Gaming Ltd.'. Each allow you to claim a welcome bonus, without interference. Yes, sister sites are completely legal in the UK and in fact make up a large portion of the betting sites on the market. It is easier for a new site to make an entrance into the market by using a shared license and sportsbook provider. Therefore you might notice that some sites look really similar to each other, as their layout is virtually the same, or slightly changed.

Hyper Sports

Yes, as long as the network allows it. Licence holders which allow for multiple bonus claims: You may be thinking of having a family member sign up with their own name and email, but as the T&Cs often state – only one bonus per household and IP address is allowed. If a relative of yours were to open an account with the same bookmaker as you, in order to claim a welcome offer, the best odds of that happening would be if they live at a different address and use a different Wi-Fi network. Closure reasons and the bookmaker group determine your options. Inactivity or business-related closures may still allow access to sister sites. Horse racing fans get Bet Builder too, now extending into win, each-way, head-to-head, and finishing position combos, as well as the best guaranteed odds on UK events. The William Hill mobile is loaded with features, including in-play betting, live streaming and partial cash out, while winning limits reach up to £2,000,000 on football, dwarfing most rivals! Licenses: UK, Malta, Italy, Denmark, Spain, Belgium, Germany, Sweden, Mexico, South Africa, Portugal, Ireland, Poland, France, USA Betway offers a strong initial impression upon registration, with two distinctly different welcome bonus choices: 'stake 10 get 40 in free bet tokens', or receive £30 matched free bet if your first acca loses, with a further 30 Uber Eats voucher. The welcome offer has clearly been formulated with the bettor's best interests at heart. Now, you will most likely be accustomed to standard 'bet 10 get 10' welcome offers, this really has pushed your average free bets into the stratosphere!

3. Sky Bet – Best for Sign Up Offer Value

A good example is the LeoVegas Group, where players can claim promotions from brands such as BetMGM, BetUK, LeoVegas and 21.co.uk. 5 bonuses per player (across the network)ProgressPlay follows a different model, allowing players to claim up to five welcome bonuses across its network of betting sites. Because the allowance is limited, choosing which offers to claim becomes more important. I remember when I claimed my first bonus, and one of my mates was excited to show me the next one he’d found. Back then, there was no such resource, so it was really up to chance whether we could claim a welcome offer.

Step 1: Verifying the Bookmaker’s UKGC Compliance

The market has grown significantly since then, with hundreds of bookmakers to choose from. Creating this guide has helped lift the fog, grouping all the bookies in a simple and organized way, so I hope it's as helpful to you, the player, as it is to me. Most betting companies only allow you to pick one bonus within their network. ProgressPlay Limited is a slight exception, as they allow 1 sports and 5 casino bonuses across all bookies under the licence. Usually you can claim one sports or casino offer per player/household.

Why Does BetMGM Offer The Best Online Casino Bonus?

The way it plays out is as follows: you can only claim one casino offer per player for the whole licence, as in the case of Videoslots Limited. But sometimes you can take advantage of multiple offers – Rank Interactive Limited allows one sports or casino offer per brand. You can also claim both Paddy Power and Betfair's offers, under PPB Counterparty Services Limited. If you try to sign up for 2, 3 or more ProgressPlay sites and want to claim more than 1 sports welcome offer – you simply won't be able to. What could happen is you decide to deposit funds and place a bet, but then not receive a free bet when that punt settles. Things get off to a good start with the bet £10 at odds of 2.0+ and get £30 in free bets welcome offer. However, its loyalty program, Unibet Rewards, is the head-turning feature. It gives you personalised offers based on how you actually bet. I’ve locked in profit boosts, combo boosts, and free bet tokens. Every day, there is a new reward, which is tailored to your sporting interests. Horse racing fans get Uniboosts, three odds boosts a day on UK and Irish racing, and Best Odds Guaranteed from 8 am daily.
