Online casinos based in the UK will often offer casino bonuses to entice new players through their digital doors. They'll also have rewards and promotions to keep members happy so that they remain a loyal customer.
There are several types of rewards and bonuses. Welcome bonuses will often match the first deposit of a new account, so savvy customers will have double the amount to play with. There are also free spins that are usually tied to specific slot machines, offering members the chance to play these titles free of charge. No deposit bonuses can offer free spins or bets without a new punter having to place money in their casino wallet, giving them a chance to try the casino without stumping up any cash.
There are many more bonuses and rewards, often tied to a loyalty or VIP programme where members earn points and climb to higher tiers based on how much they play at the casino.
Check out our guide to find out how online casino bonuses work, how to go about choosing a bonus, and where to find the best casino bonuses in the UK.
How Do Online Casino Bonuses Work?
Online casino bonuses are offered by casinos to reward new customers and loyal members alike. If a player wins using a bonus, such as a free spin or deposit bonus, there are usually wagering requirements that they will have to meet before those winnings can be withdrawn. If the requirements are not met within a certain timescale, then the winnings are forfeit.
Finding the Best Casino Bonuses UK
Searching for the best casino bonuses in the UK can often be like trying to find a needle in a haystack. There are hundreds of online casinos competing for your custom, so they often try to outdo each other with their promotions.
The easiest way to find out which casinos are offering the type of bonuses you may be interested in is to use a casino comparison site. These online tools will run searches based on specific bonuses or how much those bonuses are potentially worth.
Once you've found a selection of casinos that meet your criteria, it's worth investigating what the wagering requirements of each casino is. What is best for one player may not be best for the next. Whether the wagering requirements are achievable will depend largely on your budget and how often you visit online casinos. Winnings may be void after a short time period, or they may require more wagering than is possible for you in your playing time.
Another factor to consider is the casino itself. While one bonus may entice you, another casino may have regular bonuses that could prove to be more valuable in the long term. The casino with the initial biggest bonus may not be the one that's best suited to your playing habits, so it's worth trying it and getting a feel for it first.
How to Choose a UK Casino Welcome Bonus
Online casinos have a number of different welcome bonuses they offer in order to tempt new customers. For example, a casino might offer free spins on a slot game just for registering. However, if you do win anything, there'll be wagering requirements to meet before those winnings can be withdrawn.
Deposit bonuses match a player’s initial deposit up to a certain value, for example, 100% up to £100, which would give the player a total of £200 to bet with. Some of these bonuses are for one single amount, while other deposit bonuses offer several tiers so that players must make two, three, or even four deposits in order to take full advantage of the offer.
Casinos often offer free spins as a welcome bonus, either on its own or as a sweetener on top of a deposit bonus. These allow players to try the casino for free, although they're normally restricted to one game or software company. Again, any winnings from these free spins and rewards would be subject to the wagering requirements of the casino, so it’s important to read the terms and conditions and understand them before betting.
Can You Cash Out On an Online Casino Bonus?
Most casinos will state that any online bonus is credit for playing at the casino, and not money that can be cashed out. Similarly, the winnings from any promotion or casino bonus will be subject to wagering requirements. These will dictate how many times the winning funds must be gambled before they can be withdrawn.
