Comparing the Best Horse Racing Betting Sites

In order to achieve a definitive list of betting sites, our team of experts at Bookies.com take several factors into consideration. While it’s important for readers to get a welcome offer when they sign up, this needs to be a straightforward offer where customers understand the steps required. There also needs to be a clear chance of landing a return with the bonuses.

Beyond the welcome bonus, there should also be exciting horse racing promotions available with top horse racing bookmakers. We would expect best odds guaranteed for UK and Irish racing along with daily price boosts. Even better if there are extra places for each-way bettors and the chance to get money back or a free bet on selected races or concessions like acca insurance.

Established Site Reputation

While brand reputation isn’t the be all and end all, many of our readers like to opt for an established horse racing bookie that has decades of experience in the industry. It’s always nice to sign up with a betting site that has solid credentials, especially if your chosen £5 deposit betting sites have competitive prices for UK and Irish meetings along with races taking place further afield.

Top Horse Racing Betting App

We also want to see a quality horse racing betting app available from these bookmakers, with iOS and Android users wanting to download these apps and place bets on the move. It’s often the case that the apps are updated with added features, with customers ideally being able to receive offer notifications and have a user-friendly experience on a regular basis.

Customer Service

Customer service is clearly also an important aspect at fast withdrawal betting sites. That means Live Chat on a 24/7 basis as a given, with bettors being connected to a support representative within minutes and able to have their query adequately resolved. A range of payment options is another consideration, with app users often wanting to make deposits and withdrawals using many different modern methods, with the likes of Apple Pay betting sites and Trustly betting sites becoming more popular in recent times.

When signing up with top horse racing bookmakers, the process is pretty similar across the board. It all starts with choosing an operator from the list at Bookies.com and tapping through to the landing page. Here you will find details of the sign up offer, and you can begin the registration process, which should only take a couple of minutes. 

The sort of information you are required to enter includes name, address, date of birth and email address. You will also need to create a username and password, along with a memorable question that can ensure further protection for your account. 

All your personal information is kept secure, and you may be asked to verify your identity, which is part of customer protection and the know your customer requirements. You can then go ahead and make a first deposit, choosing from the range of payment methods that are available.

How to Bet on the Grand National at Horse Racing Betting Sites

Once you have a funded betting account and placed any qualifying bets with one of the top horse racing betting sites available at Bookies.com, you should be in possession of some top drawer Grand National free bets.

You can head to the horse racing section of a bookmaker site where you will find all the Aintree races listed, but make sure you take a look at the latest Grand National trends to help inform your punts. Tap on the race that interests you the most, and you will find a list of runners along with information pertaining to form, weight, trainer and jockey.

In order to bet on a horse running in an Aintree race, you should tap on the odds of your chosen selection. This will automatically add that horse to your bet slip. You can then choose how much you would like to stake on that selection, with a customer needing enough money in their balance to cover the bet.

For a multiple bet, you can add further selections to your bet slip before deciding on the type of bet you want to place and how much you would like to stake.
