What is a bookmakers welcome bonus?

Before we go any further, it is of course necessary to understand what are the welcome bonuses that are offered by best betting sites. It goes without saying that more and more sports betting sites are present on the UK market every day. From Bet365 to William Hill, Betway to Karamba, Bet-at-Home to 888sport, there are a variety of operators that offers internet users the opportunity to place their sports bets online - each of which has their own unique qualities, as well as some small areas of improvement. Such a significant volume of bookmakers inevitably creates an air of competition to attract sports betting fans, which is where welcome bonuses play an important role.

Coming in many different kinds and forms; these welcome bonuses offered by bookmakers are advantages promised to lovers of sports betting - an incentive to open an account with these well-known bookmakers. In short, it is the bookmakers way of saying "Register with us to bet, we offer you such advantages when you sign-up". Not unlike many other aspects of daily life, these actions reminds us of establishments such as banks and supermarkets with their constant promotions.

In the end, the real winner remains to be you, the bettor, as you will be able to enjoy the numerous sign-up offers of these betting sites, particularly by registering with multiple betting sites. Indeed, just because you register with Bet365 doesn't mean that you shouldn't also register with Betway, and vice versa. In the end, if all bookmakers bonuses on the market are available to you, it will allow you to enjoy huge benefits when placing your bets. It is up to you to register for these benefits, and it is in this mind that we have listed the most appealing welcome bonuses - don't miss out, registration takes only a few minutes!

What are the different types of online bookmakers sign-up offers?

Although over time bookmakers have gradually standardized their various bookie sign up offers, know that these famous sports betting bonuses take different forms, and vary in generosity. Here are the most common, which we find today on the market of UK bookmakers.

Deposit bonus

Perhaps the least popular bonus of the moment, the bonus deposit works in a way that the first amount of money that you pay into your player account will have an influence on the amount that will be offered by the bookmaker. Generally, the value of your welcome bonus will be 100% of the deposit you pay. For example, if you deposit £100 when you register, you can expect to receive a £100 when opening your account (depending on the conditions of obtaining the welcome offer). Without doubt a generous offer, but one that is becoming less and less present on the market in recent years.

The first-bet refund bonus

According to our specialists, this is the best type of bonus currently found on the sports betting market. Often not requiring any real condition to be withdrawn, this refund bonus offer will, as its name suggests, consist of a refund if your first bet is not a winning one. For example, you bet £100 on Liverpool to win against Arsenal in your first bet, but the Reds take a draw at the Emirates? You will then be refunded the amount of your bet in full, and you can safely remove the £100 present on your account (if no other specific condition is dictated by the operator).

The free bet bonus

The third and final type of bookmaker bonus that we find on today's market, is the free bet which is always interesting to consider. As with the first-bet refund bonus, the free bet bonus involves the bookmaker paying out the amount of your first sports bet if your bet is not a winner. The difference between a refund bet and a free bet is that you must play with the same site, as the amount you receive is refunded as a free bet on the bookmakers site. It will be reflected as a second bet, so make sure to read the terms and conditions provided by the bookmaker in order to use this free bet. It is still a generous type of bonus, and is one that is widely appreciated by punters.

No Deposit Bonus: Is there really such thing?

Contrary to the situation which existed a few years ago, bonuses that do not require any payment beforehand no longer exist on the sports betting market. Although some special operations can be organised from time to time, no deposit bonuses seem to have fallen in favour amongst bookmakers, much to our regret. Although we are hoping that some betting sites will prove us wrong in the coming weeks; bookmaker bonuses of this type no longer exist on the UK sports betting market, mainly because their lack of efficiency was noted amongst bookmakers.

Do not register with Unlicensed Bookmakers

It is important for us to remind you not to register with a site that does not hold a license. Being licensed means that if there are problems, they will be investigated. Safety at online sites is always important and the holding of a license that has been granted by a regulatory body is just what you want to see. The site will have had to undergo tests to be granted that license and will not want to do anything that might see them lose it. Joining an unlicensed site means there is no protection for you when disputes occur.

A bonus goes unpaid? Gains to which you are legally entitled to never enter your account? Your personal data has been hacked? Unfortunately, in this situation, there's nothing to be done. Which is why, as experts in the world of online betting, we strongly advise that you avoid unlicensed sites offering  bonuses. It may well be that the bonus offered has so many restrictions it is difficult to withdraw anything anyway. In any case, there are plenty of opportunities available with the best licensed bookmakers on the market - why look anywhere else?
