How We Rate & Review

Background Check on Safety

With every online betting review, security and safety are among the most important factors for ranking a site. We start the reviews process by finding out whether the site has been fully certified and is regulated by recognisable regulatory bodies such as the UK Gambling Commission. We also investigate the kind of betting software that powers the bookies,as well as the betting margins for both the popular and less popular sports.

The bookie must be running on a critically acclaimed software provider like Kambi Games or Playtech's Geneity Limited for us to give it good rating. Lastly, on security our team of expert reviewers also confirm whether the sports betting site uses industry standard 128-bit SSL encryption to protect player data when making real cash bets in Britain.

Deposit and Check Out the Customer Service Help Options

The rating that a betting site will receive here will primarily depend on how smooth the process of loading the cash will be. Moreover, several deposit options like Credit and Debit Cards from VISA and MasterCard as well as e-wallets like PayPal and Skrill are tested. Our review team also reaches out to the customer support agents via all the available methods to check how quickly they respond and how helpful their solutions are. Online sports bookies with fast response times and helpful answers will score highly in this criterion and do well in our reviews for online betting sites.

The Range Of Sports and Betting Types Provided

After the playing cash for online bets is loaded, our review team places bets on a few different sports markets available on the site. The team starts with wagering on most popular sports such as football, horseracing, rugby and NFL. Then we switch to less popular options such as snooker and yachting.

One of the main aspects that we highly consider is the presence of an in-play betting section coupled with HD live streaming. If available, we then try out a few live bets at the sportsbook. After all the sporting events are tested through different types of bets like the head to head and/or triple head and even a handicap bet, we shift to checking transaction speeds. The leftover cash in the account is cashed out to gauge the speed and efficiency of the withdrawal process.

Include the Betting Site in Our Top-Rated UK Shortlist

Once everything under our non-negotiable standards checks out, we add the sportsbook to our recommended top picks for online bets. So, you truly can expect the cream of the crop when you visit OnlineBetting.co.uk.
