Bookmaker reviews UK are quite handy when you are trying to decide which bookie to sign up with. We all have our preferences when it comes to betting – some of us are bonus hunters, some appreciate good promo program, others go for the odds. That’s why it makes sense to consult a good bookmaker reviews website before opening an account with one. We do have a section for the latest bookmaker offers, which you may like to check out before signing up.

Best Sign-up Offer: Ladbrokes

Let us be clear when we say that the impact of a sign-up offer on a new player depends entirely on their financials, as players who enjoy different levels of stakes will feel more strongly about a given offer than others. With that said, high stakes bettors may not like the sign-up offers on display from our list of the best betting sites, as they tend to be more friendly to low-stakes players who would notice a tangible boost from a free £50 or less. In this case, Ladbrokes gets the nod for having the highest amount of matched bet funds available to its players.

Ladbrokes is currently offering players welcome bonus, meaning that players who place an initial wager with the site will receive a free bet good for up to that amount. This means that players can wager over the required minimum bet, but the free bet reward will remain the same in any case. While there are odds requirements to abide by, Ladbrokes new customer offer is the best sign-up bonus available among these best betting sites.

It seems that the other sites on this list of the best betting sites also tend to favor the bet and get free bets model. This is by no means a bad model, and William Hill and the rest of the sites aren’t wrong for using it, they are simply outmatched in this category, though.

Best Betting Markets: Paddy Power

Perhaps more of a sentimental pick than anything else, Paddy Power wins the race to the best betting markets among the best betting sites. The site is notorious for its over the top betting markets and novelty wagers. If you want to wager on football, you can wager on football. If you want to wager on basketball, you can wager on basketball.

Where Paddy Power is not victorious, though, is in its selection of horse racing markets. William Hill is by far the best option when it comes to horse racing betting, as it is the winner among the best betting sites by several lengths when it comes to horse racing. This is especially true in the UK and Ireland, where William Hill prides itself on its odds, as well as the sheer number of markets that they make available to bettors, along with races from the United States and the rest of the world.

This again is a product of which betting markets you most like to take advantage of. If you are a more traditional sports bettor, you will probably enjoy a William Hill or similar best betting site more, as opposed to someone looking to have fun who might prefer Paddy Power.

Best Mobile App: William Hill

The mobile app category goes to William Hill, who tops the rest of the best betting sites with a mobile app that manages to differentiate itself from the rest. The main reason for that differentiation is horse racing coverage, as William Hill offers a truly excellent view of horse racing betting from its app. Bettors can easily place multiple wagers within the same race from one screen, in a visually appealing way, with graphic visualizations of the competitors and their odds to spice up the genre.

William Hill also has a great deal of live streaming available through its mobile app, something only Paddy Power can match them on in this list of the best betting sites. Thanks to this factor, in addition to some going above and beyond in the horse racing field, William Hill wins the mobile app battle between the best betting sites.

Credit to the rest of the sites on this list, though, for all having a strong offering on mobile devices, whether that is on a mobile app, or just a browser-enabled mobile site.

Odds: William Hill

William Hill wins another round between the best betting sites here, relying on some superior odds to get the job done. It must be noted that when it comes to all of the major online betting brands, there generally isn’t a huge difference in between them as far as which has the best odds, but small variations make the difference in this round, and William Hill is the best at capitalizing on the small variations that this round has to offer.

William Hill offers the best odds on horse racing in the UK and Ireland, something that other betting sites may try to keep up with, but simply cannot. Also, William Hill offers regular bet boosting promotions to keep their players getting the best possible odds whenever possible. While other sites may have strong odds as well, William Hill takes the crown in this battle of the best betting odds at the best betting sites.

FAQs: Best Betting Sites

What do I need to register at an online betting site?

To register at an online betting site, one must be of legal age to wager in the area in which you live. This is generally 18 years old, but it never hurts to check your local laws. At some bookmakers, you need to possess a bank account to wager, as that is where you will be paid out, but this varies depending on the rules of the bookmaker, along with the funding methods that they offer. Always be sure to check on these requirements before attempting to set up an account at a bookmaker.

While this can seem a bit inconvenient or strict at times, depending on a bettor’s feelings on such regulations, it should be comforting to know that the best betting sites are working to make sure that their players are being protected with these measures. While some bettors would prefer to simply use a functional payment method and start placing their bets, the overall well-being of players is preserved by these rules being in place.

With regards to age restrictions, it goes without saying that children should not be able to risk their funds or the funds of their parents at betting sites until they are old enough to make decisions with clarity and a level head. As far as banking requirements are concerned, those rules ensure that players are in full control of their funds when making deposits and withdrawals, as opposed to those funds going to an online wallet that can be hacked or subject to other criminal activity more easily than a traditional bank account can.

Playing at a betting site that adheres to specific rules such as the above is not required, but can serve as a nice bit of protection against issues that could cause headaches down the road. Whether or not those rules are for you is your decision, but having the power to take advantage of them is vital.

How do I register at an online bookmaker?

Registering at an online bookmaker is simple, and convenient. Simply visit one of the best betting sites above, and find the Join Now or Register button. From there, you will be guided through a form to fill out containing your personal information and the information you want to use to login to the site. This is fast, simple, and doesn’t waste any of your time.

Of course, when creating an account, you will want to keep an eye out for various promotions available to you in the way of sign-up bonuses. We have covered some of the promotions available at the best betting sites listed above, but those sites and others always have other promotions going on that make signing up with them more appealing.

Depending on your budgets and betting strategy, some of those promotions are more beneficial than others, so be sure to find one that matches your needs before you set up an account.

Also important to do before setting up an account is to make sure that the site you are signing up with offers adequate betting markets in the areas in which you like to wager. We mentioned some strengths of some of the best betting sites above, but everyone has different interests, and should make sure that those interests are represented in their chosen betting site.

If you are a fan of a more niche sport, you will want to be able to bet on that, and need to make sure your chosen site can accommodate you. The same can be said about live wagering, which is a great way to find value in the middle of a match if you know what you are doing.

These are just a couple of the things that every bettor should look for before registering with an online bookmaker. It may take some time and feel like a lot of work, but is greatly beneficial.

Is it safe to do deposits and withdrawals at online bookmakers?

Yes! Online bookmakers are subject to stringent financial regulations as they take in funds and pay out funds to players constantly. They would not legally be allowed to continue doing business if there were any safety issues with depositing and withdrawing funds.

This is the biggest benefit to doing your sports betting with a trusted bookmaker brand. While the biggest names in the sports betting industry do not always have the most generous odds or sign-up bonuses, what they do have is security, and the ability to provide their players with safe deposits and withdrawals, and a place to play where they know that everything will run smoothly on a consistent basis. There is a lot to be said for that, and is why the best betting sites above are highly recommended.

Can I set a betting limit?

Some bookmakers do allow players the ability to set a limit from within their site, but others do not. This is something to look into before creating an account. However, even at sites that do not offer this feature, it is always important to keep a limit in your head before you place any bets. Responsible betting is the best kind of betting.

Generally speaking, this feature can be found in the account security section of big name betting sites, with players having the capability to set limits as to how much they deposit, what games they can play, and other things that can make the online betting experience just a little more secure across the board.

The big benefit here, of course, is the ability for players to take care of themselves from a financial perspective, by not allowing themselves to deposit more than they can afford, or to play games where they tend to lose track of how much they have spent. This means that players can make sure that their games remain fun, without the ability for them to become stressful for monetary reasons.

All of the best betting sites also have links available to literature about responsible betting, to make sure that anyone who feels that they need information on that topic has immediate access to it. That commitment to responsibility is another benefit of using a trusted sportsbook brand, and why they are so highly recommended.
