How we Rank

To feature on 123Bookies, we review each online betting site as thoroughly as possible, making sure we only include the very best bookies. They need to demonstrate to us that they are one of the very best betting sites for UK players. In order to achieve a top rating we judge them on several topics, where we have a thorough checklist with questions like:

☆ Software/Games

Do they have sleek and fast design? Does it have fast loading times? Is it easy to navigate the site? Do they have a clear betting slip? Is it mobile/tablet compatible? Do they have a varied and extensive selection of markets and bets? Do they have competitive odds? Do they offer additional features such as cashout or inplay betting?

☆ Cashier

Is there a good selection of banking methods? Is the site secure? Is it easy to deposit funds? Are withdrawals processed quickly? Start to finish, is it an easy and quick process?

☆ Bonuses/Promotions

Are their bonuses competitive, engaging and easy to claim? Do they offer a Welcome Bonus or Free Bet for new players? Do they keep existing members happy with regular promotions and enhanced odds? Is it easy to understand their offers with clear terms and conditions? Do they reward their loyal players?

☆ Customer Service

Do they have an easy to use Help section? Do they have easy to find contact information? Is the information clear, including hours of operation, country codes etc.? Do they offer a variety of customer support methods – e.g. Email, Phone, Chat, Mail? Are they quick to respond? Do they offer good service? Are they polite? Are they knowledgeable?

☆ Overall

Before we give a betting site a toprating we’ll answer all the above questions and more, and we’ll need to get a big YES to all of them to issue a 123Bookies approval. Of course all bookies will also need to be mobile and tablet compatible and be UK regulated to meet specific standards for fairness, safety and security.
