The best betting sites UK - CasinoHawks tips

When it comes to choosing your online betting site, first and foremost you should check whether or not the site in question is offering odds on the games you intend to bet on. This is becoming easier as time goes by, since all major online betting sites are now offering hundreds of betting options, across all sports and events. You can expect anything from football, tennis, basketball and volleyball to horse racing, motor racing, greyhound racing, surfing, darts, placepot and esports betting. And for each match available, you can expect dozens of markets on each and every event.

Another interesting catagory you find across all the best betting sites these days is the Special section, which includes odds on popular TV shows, awards, concerts and even Royal baby betting!

Once you’ve identified a couple of sites that will be offering odds on the event that’s of interest to you, it’s worth checking out whether the site also offers what is known as in-play or live betting. This involves the possibility of betting on an outcome once a game has started, so you might take advantage of changes in momentum to make more accurate predictions. In-play betting offers many other advantages; the odds keep changing and may turn more in your favour, and there will also be additional betting options depending on what happens during the game, which will make your betting experience much more varied and exciting!

And now, it's time to have a look at our (non-exhaustive) list below to see what kind of bonuses you can expect from some top online betting sites:

£ 10 free bet on first deposit. Min. deposit £20. Bonus bet valid for 7 days. Min odds 3/1 (4.0). Min. 3 selections. Bonus bets cannot be split. Cash out not eligible.

£ 50 no wagering bonus on first deposit. New UK customers only. Min. £20 deposit. Max. bonus £50 consisting of 10 wager-free bonuses of £5 each. £5 awarded for every £100 wagered. Bonus expires 7 days after registration.

Find the best betting odds

Of course, another factor to look out for when identifying the bestbetting sites for the UK are the odds on offer; try to find a betting site which offers reasonable and value odds, and make use of an odds comparison site to try and determine the most favourable ones for a particular game. To do this, you need to look at what is known as ‘implied probability’; essentially, you have to identify those odds whose implied probability is less than what you think the actual probability is. This means that according to you, the online betting site considers that a team is less likely to win than you think it actually is, and therefore offers high paying odds if you back that team.

Last but not least, another factor we recommend looking out for, and which we shall be examining in more detail below with regard to our recommended betting sites, are the offers or promotions which online betting sites are running, and which are UK players may start taking advantage of as from today.
