Online casino bonuses UK

UK casino bonuses

Since online gambling in the UK is regulated by the UK Gambling Commission, there are some rules that casinos need to follow when offering bonuses. Rules that are set to protect the player and make gambling in general more fair. Which is nice, but it of course limits the size of the casino bonus offers to some extent. But in our opinion, it is more important to have fair terms than large amount of bonus money.

Every UK casino bonus is forfeitable

Forfeitable casino bonus means that the bonus money and the real money are separated. So you as a player have the possibility to withdraw the real money at any point in time. Including the potential winnings. UK online casinos also need to make it very clear what money they are using at all times.

UK Casino bonus terms & conditions: What keep an eye on?

UK casino bonus terms and conditions

In the UK all the terms and conditions apply only to bonus funds. Wagering is the key thing to keep an eye on when comparing casino bonuses. Only bonus funds need to be wagered in the UK as your own funds you can withdraw at any point.

Casino bonus wagering

UK casino bonus offers can be either bonus money or free spins. Bonus money has the wagering requirements directly implied but with free spins the bonus wagering is for free spins winnings which essentially are bonus money as well.

Best online casino bonuses are wager-free, but these of course aren’t that common and are always free spins without wagering. For bonus money, 35 times wagering on bonus money is pretty much the best that the market currently offers. Typically wagering need to be done in casino slots as other casino games have lower or non existing wagering contribution.

Unless the wagering is completed within a given time frame the bonus funds expire. Meaning that they will be automatically removed from the account and the bonus balance will drop to zero.

Other casino bonus terms

While wagering requirements are the most important thing of any UK casino bonus, you also wanna check:

All UK casino bonus sites need to clearly provide the information above. Of course you as a player have a responsibility to make sure you choose a suitable casino bonus offer for your needs. It’s pretty simple to estimate how long it would for example take you to complete the bonus wagering.

Every casino slot spin in the UK lasts 2 seconds by law. Wagering for example a 100 pounds in bonus funds with 35 times wagering would take roughly two hours when betting 1 pound a spin. Bet two pounds per spin and you have split the time in half.

Choose online casino bonus for your needs

Choosing UK casino bonus

Best online casino bonuses are suitable for most players. But of course, every player is unique and you should choose a casino bonus that is the best casino bonus for you. Here are some tips what to keep in mind when comparing casino bonuses:
