Online betting bonuses are always sought after by those who hold accounts with the various betting brands in the industry.

Of course, these bonuses come in various different forms. It isn’t just free bets for existing customers that are available either because the top brands come up with different incentives all the time. If you want to bypass all of this information, you can always check out the brands that we’ve listed on this very page.

These have all been handpicked by our team of experts, and you can sign up with as many of these sites as you please.

What are existing customer offers?

Simply put, free bets for existing customers are those that are open to all players of a site that currently have an active account. These are completely different from rewards that are available exclusively for new customers. The key difference is that new customer offers are reserved for those that are signing up with a site for the first time, whereas existing customer offers are for everyone to enjoy. 

In order to find out what existing customer betting offers are available at any online site, you need to check out the section that is designated for bonuses or promotions. There will almost always be a link to this section from the homepage, and from here, you can basically pick and choose which offers you’d like to claim. 

Best Existing Customer Offers

Existing customer betting offers come in all shapes and sizes. In the case of sports betting, they almost always provide you with a way to bet without using purely your own money. With this in mind, let us show you some of the more typical existing customer offers that you’ll find with the top brands. 

Bet Free Bet

This is arguably the most common type of existing player bonus, and as the description suggests, you will need to stake some money in return for a free bet. A classic example would be where a site states you must bet £10 in exchange for a free £30 bet. Of course, the actual monetary values you’ll find can be different from site to site. 

Money Back as a Free Bet

This kind of offer is usually tied to a particular situation. For example, you might find that in football, you will get your money back as a free bet should the game end in a goalless draw. Alternatively, in horse racing, you might see that you can get your money back as a free bet if your chosen horse loses by less than a certain number of lengths. 

Profit Boost on Winning Bets

In this instance, rather than taking advantage of any free bets for existing customers, you will simply receive a boost on top of the original winnings. As an example, if the promotion stated that players will receive a 25% profit boost on all winning bets, and your potential return was originally £100, you would receive £125. Note that the percentage can vary for these kinds of betting incentives. 

Mobile-exclusive offers

As the name indicates, mobile-exclusive offers are reserved for players who choose to download the native app and claim an offer. These offers are regularly unavailable on desktop sites, and they generally work as a way to encourage customers to download the sports betting app. These offers can occasionally be a blend of free bets, deposit boosts, insurance wagers, and profit boosts. 

FAQs

  • How often do bookmakers hand out free bet offers to existing customers?

    While there is no standard regularity of free bet offers for existing customers, the best sites do tend to come up with such offers on a weekly basis. It is actually quite common for the top brands to create several free bet offers during the course of a week, and of course, you can claim as many of them as you like. 

  • Do I need to create a new account to claim the bonus?

    If you already have an account with any of the mentioned bookmakers, you can simply log in and claim the offers that are available. However, if you do not yet have an account with the sites identified on this page, yes, you will need to sign up to claim the rewards. 

  • Are free bet offers for existing customers the same value as offers to new customers?

    No. You’ll generally find that new customer offers are much higher than existing customer offers, and that is because new offers are the ones that pull the punters in to begin with. With that said, while existing customer betting offers might be lower, they are still created by the best brands on a very regular basis.
