The number one most preferred casino bonus in the United Kingdom is the welcome bonus. This offer rewards newly-registered players with match deposits bonuses as well as some extras like Free Spins on slot games.
British players are more than willing to register at several online casinos and determine which is the best, hence they do like to claim these bonuses. It is worth mentioning that welcome bonuses come with quite a few terms and conditions that state how to claim them.
Next up, loyalty programs are also popular here. There are many high-rollers in the UK and loyalty programs at online casinos will provide these players with exclusive offers such as unique bonuses, personalized account managers, higher withdrawal limits, Free Spins, cashbacks, etc.
Finally, all types of sports bonuses, especially cashbacks are welcomed with a warm heart. It was mentioned earlier that British players are extremely fond of sports betting, so sportsbook bonuses such as free bets and reload bonuses are popular here.
