It’s challenging to find the right bookie since they all try so hard to attract new customers. Many offer massive bonuses and seemingly unique promotions, but when you take a look at the terms, it becomes clear that they’re anything but. Merely scanning the Internet and looking for the biggest betting bonuses won’t do you any good. You need a site with a fair reward that’s reasonably-sized and with fair T&Cs.

The good news is we have found the top new bookies with excellent bonus offers. No need to wander the Internet and waste hours looking for the top betting bonuses – everything you need is already here.

The list will be constantly updated with new additions. Every time a new bookie enters the market, we will review it and look through its offers. An exclusive welcome bonus is not enough for us to give it a passing grade. Great bookies offer a slew of bonuses and promotions, including deposit, no deposit, and loyalty bonuses as well.

Types of Betting Bonuses

One thing you need to know about bookmaker bonus bets – they come in different shapes and sizes. You may have heard everything about free bets, but there are also deposit and no deposit bonuses, as well as other types of rewards you need to take a look at.

Loyal customers can get their hands on a slew of great bonus offers, including referrals, cashback, and reloads. The last two are reserved for regulars who spend a nice portion of cash each week and month. With cashback and reloads, you’ll be able to ‘reload’ your bankroll for the challenges ahead and stay in the game for longer. Think of both as a loyalty reward for your betting.

The more types of bonuses a bookie has, the better. Of course, you should claim them all if the bookmaker allows it and the terms are fair. You see, betting bonuses don’t come with any strings attached. There are some requirements you must meet to get your winnings out.

Deposit Bonuses

Deposit bonuses are the most common type of bonus in both online casinos and betting sites. These freebies work simply – you get a reward whenever you make a deposit. A welcome bonus, for example, is a deposit bonus. It requires you to sign up and make a deposit before you qualify for the offer. Since they need you to deposit to claim them, deposit bonuses come with a long set of terms and requirements. Read these before registration to learn if that particular sportsbook is the right for you and if the reward is any good.

No Deposit Bonuses

A no deposit bonus is the opposite of deposit bonuses. You get a bonus without making a deposit first. As such, no deposit freebies are among the best sports betting site bonuses. However, they’re also pretty rare – not all bookies have them. Keep in mind that these bonuses don’t come for free. You still have a set of terms and conditions to go through if you want to get your winnings back to your account soon.

Sign Up Bonuses

Sign-up bonuses are also known as welcome offers. As the terms suggest, these bonuses are given to new players upon registration. In most cases, you will also need to deposit to claim the extra funds. It is the most common online betting bonus you can claim. Welcome offers come in different shapes and sizes. Most betting sites will offer a deposit bonus, while others will give you free bets to enjoy.

Free Bets (Bonus Bets)

As mentioned, most online bookmakers will offer a free bet on sign-up. Joining a new bookie will give you a chance to start your journey with a free bet that you can spend on your favorite sports markets. Make sure to check the bonus terms and conditions first. A site may prevent players from certain countries like the USA, Kenya, or Australia from claiming the free bet. They will also state the terms under which you can spend the free bet. In most cases, you will be able to place the extra funds on specified NHL odds or NFL markets.

Deposit to Get Free Bets

Most free bets you can claim at online betting sites will require you to make a deposit. It is especially true for welcome free bets, which are among the best betting bonuses in the UK. As the name suggests, they’re only activated upon a deposit. For welcome free bets, it’s the first deposit. For any other free bets, it’s just a further deposit.

Bet to Get Free Bets

Some betting sites for UK players offer free bets that can be activated when making a deposit and bet. For example, the terms may state that you’ll be given a free wager after placing a bet on football markets with odds of 1/1 or higher. As soon as that condition is fulfilled, you’ll get a free wager that you can later spend under specific terms and conditions.

Loyalty Free Bets

Loyalty free bets are given to a betting site’s most loyal customers. The best bonus betting sites will roll them out weekly or monthly. While it may seem like too much money to spend for bookies, it’s a way to keep customers happy and betting. Of course, these free bets come with specific terms and requirements, too, but you can expect lower wagering. After all, a loyal customer deserves it.

VIP Club Free Bets

If you happen to join a betting site’s VIP club, you’ll be swimming in prizes before you know it. VIP programs usually give a rolling free bet offer to the most loyal customers. These programs may come in different tiers – the higher you get, the beefier free bets you’ll earn.

Bet Insurance (Risk-free Bets)

What if you could insure your bet and cover your losses if your prediction doesn’t go right? One of the most popular bonus bet offers for UK punters; bet insurance is most commonly a paid service that will give back at least part of your profit. Read the terms for this bonus before accepting it since they can confuse new punters.

Betting Promo Codes

At some sportsbooks, you will need to use promo codes to unlock a bonus. Also known as bonus codes, these are a string of letters or numbers or a phrase you need to enter to claim the reward. Betting promo codes are listed on the promotion’s page. If you don’t enter the code when prompted, you won’t argue the bonus. Keep this in mind if the bookie requires you to use sports betting bonus code. If you have any doubts, you can get in touch with a customer support agent.

Betting App & Mobile Bonuses

As you surely already know, the betting industry has mostly moved online. Punters these days enjoy betting on their mobile devices more than betting on their PCs. Why sit in front of a computer screen when you can do it anytime and anywhere? It is possible via betting apps, which may also feature a special mobile-only bonus.

It is usually done to promote the betting app and attract new customers. You don’t need to know the specifics – if the terms are fair, claiming a mobile-exclusive bonus is a must. In most cases, it’ll probably be a free bet.

However, mobile bonuses can also come in other shapes and sizes depending on what the betting site is trying to achieve.

How Do Betting Bonuses Work?

Many of you will be wondering how a bonus bet works. That’s a legitimate question. New punters rarely know the specifics of online sports betting bonuses, ending up confused about whether to get one.

We’re here to clear things up for you. Do you know how betting shops have promotions for new players or regulars? Well, it’s the same with online sports gambling bonuses, except they’re much better. You can use the extra funds to bet online or on the go, and they often have great terms and conditions that allow you to win a nice sum of cash.

Of course, they don’t come for free. Betting bonuses are subject to a set of terms and conditions that must be met if you don’t want to lose the extra cash. Among these, wagering requirements are the most important. To put it simply, these requirements state the number of times you have to play the bonus funds over before you’re able to withdraw any winnings.

If you get a free bet worth £10 and need to wager it 10 times, you must place bets equal to £100 to get your winnings.

The good news is that some sites will give you bonuses for free, although these are rare. Once you complete the wagering and any other terms that must be met, you’re free to keep the money you’ve won with the bonus.

What is a Betting Bonus?

A betting bonus is a gift a site gives to its new or existing customers. In many ways, it’s similar to land-based casino comps, but you won’t be getting free drinks this time. Online bookmakers hand out free bets and other types of bonuses to attract new customers and retain their seasoned vets.

You should go for a betting bonus if the terms allow it. Keep in mind that you need to give these a careful read. There might be nooks and crannies in the fine print you can easily miss and, in that way, lose your extra funds.

There’s plenty of extra cash to be earned at the top online sports betting sites, from welcome deposit bonuses to no deposit bonuses, free bets, and beyond.

Why Should You Try to Get a Betting Bonus?

Who wouldn’t want to get their hands on a free bet at sites such as William Hill and Unibet? Sportsbook bonuses allow you to keep playing and possibly win some real money too. Yes, you can use a betting site bonus to win real money, but you’ll have to complete certain objectives before you’re able to withdraw winnings.

Since you’re earning extra cash, you will be able to bet on more markets than you previously thought and increase your chances to win. Of course, there are some disadvantages to sports betting bonuses, but the pros far outweigh the cons.

Advantages of Betting Bonuses

There are plenty of advantages betting bonuses have. First and foremost, let’s address the obvious – it’s extra money you’re getting. It means more money on your bankroll and more chances to win.

If you were not sure about betting in some markets, such as Esports bets, you could do it with a bonus. Why spend your own money when you can do it for ‘free’? Rewards are a great way to experiment with some markets, and if you’re lucky, you may win a nice amount of cash.

If you want to be successful at sports gambling, you’ll need to use strategies too. Instead of spending a lot of your cash to try some, you can use that welcome bonus you’ve got upon registration (or otherwise). Since it’s bonus money, you won’t have a hard time even if you fail to score. It won’t be money out of your pocket.

As you can see, there are plenty of advantages of getting a betting bonus, which is why it’s essential to claim the extra funds.

Disadvantages of Betting Bonuses

While it’s great to have some extra money when betting online, you need to keep in mind that bonuses don’t come for free. The biggest disadvantage is wagering requirements. While the top bookies will keep them low, big bonus bets will likely come at too high a price.

What’s the point of getting a gigantic bonus if you need to roll it over 50 times? Those terms are simply too high and nearly impossible to complete in a short timeframe. It’s the same with free bets. While they’re a great way to try out new markets, you shouldn’t just rush into getting them if the terms are unfair.

The fine print most punters don’t read makes betting bonuses a double-edged sword. If you don’t meet the wagering requirements, you won’t be able to get your winnings out. Since we’re all in it to win it, getting our winnings is essential. If the terms are unfair, you won’t claim them, resulting in forfeited bonus funds and no cash out.

Understanding Bonus Terms & Conditions

As mentioned previously, betting bonuses come with a slew of terms and conditions you need to read carefully. Rarely any punter reads the fine print below a bonus – almost everyone is attracted to the massive sums of cash on the front page. However, failure to read the bonus T&Cs can lead to you losing the bonus funds and the winnings made with them.

While wagering requirements are essential, there are other terms you also need to keep in mind. For example, you can’t just spend the whole bonus or free bet on a specific sports market and be done with it. Bookies will limit the maximum bet size when using the bonus funds and put a cap on winnings. After all, they won’t let you win a million with a free bet.

Below you can see a list of the most important terms and conditions you should understand before claiming a betting bonus.

Minimum Deposit

To claim a betting bonus, you need to make a minimum deposit first. In this way, a bookie ensures that players would still make a good deposit to give back some extra cash. The minimum deposit is usually pretty low, and unless you cover it, you won’t be able to qualify for a bonus. It is generally stated right below the reward on the front page or promotions page, along with the wagering requirements and other important terms and conditions. In most cases, you’ll need to deposit something close to £10 or £20 to qualify for the welcome free bet (or any other kind of offer). With that qualifying deposit, you’ll be able to claim the bonus and play with it later.

Maximum Winnings

While it would be great to win a million when using a betting bonus, bookies will usually cap the maximum winnings. Major sites such as Unibet might choose not to, but in most cases, there’s a limit to how much you can win with a bonus. And that’s OK – you’re still getting extra money for free, so you can’t expect to win such significant amounts with it. It’ll always be a nice amount of cash, though, not just a few pounds.

Wagering Requirements

Wagering requirements state the number of times you have to roll an online betting bonus over to withdraw your winnings. Wagering is an inseparable part of bonus terms and conditions and must be completed in a certain time frame before you can withdraw your winnings. They usually come in the form of 30x or 40x – this means that you should wager the bonus funds 30 or 40 times before making a withdrawal request. If you put in the offer before it, there’s a great chance that your bonus will be forfeited.

Time Limits

As mentioned, the wagering should be completed in a limited timeframe. How much time you have depends on the bonus. Free bets usually have an expiry date of a few days to a week, while bigger rewards may have a 15-30 days expiry date. All of this is indicated under the fine print right beneath the bonus offer. Read it carefully to learn how much time you have to complete the wagering. If you don’t finish on time, you will lose your remaining bonus funds and any winnings with them too.

Odds Restrictions

There are restrictions placed on odds when it comes to bookmakers with bonuses when you’re betting with a bonus. When you play with your own money, you can place bets on any odds you want to. However, when it comes to using a bonus, you will have to put them on odds specified by the bookie. The odds restrictions are in place, so you don’t bet on the highest ones and win a fortune. Together with the cap on maximum winnings, it’s a measure that protects bookies from suffering massive losses from a bonus.

Checklist for Choosing the Best Betting Bonuses

  1. If you want to earn a good bonus, you need to shop for the best ones online. It means finding a licensed and regulated bookie with rewards that have fair terms and conditions;
  2. The wagering requirements are the first thing you need to check before hitting the Claim button. If they’re too high and must be completed in a few days, those terms are highly unfair;
  3. A free bet worth a fiver or tenner may look great, but read the other terms too. There might be some things you don’t like that may affect your chances of winning something with the bonus;
  4. The best betting bonuses are not necessarily the biggest ones. Remember – the bigger a reward is, the more likely it is that the wagering will be sky-high;
  5. The markets available with a sports bonus are also important – you don’t want to spend the reward on unattractive markets with bad odds.

  • How do bonus bets make money?

    While you may get money for free, getting your winnings out certainly comes at a price. That’s where wagering requirements come in – thanks to them, bookies can make money on bonus bets. To put it simply, you will need to spend some money before getting the money won with a bonus. The wagering is usually more comfortable to complete the lower the bonus amount is. Keep in mind that you also have a limited time frame to complete the wagering. Miss it, and you will have your bonus funds stripped away.

    A betting bonus without a deposit is called a no deposit bonus. It’s rare to see it these days, but that’s what makes it special.
