All UK online casinos offer bonuses, which can be broadly classified into free bonuses that require no deposit and bonuses that require a deposit.
Read on to know about each type of online casino bonus at UK online casinos:
UK online casinos offer no deposit bonuses as signup offers. These are free bonuses that require no deposit.
Also called the casino welcome bonus, online casinos give it to all players who sign up and log in to their accounts for the first time:
Many online casinos welcome newly registered players with no deposit free spin bonuses. The no deposit free spins bonus is a popular variety of casino welcome bonuses.
Usually, you have to make a real money bet to spin a slot once. No deposit free spins bonuses allow you to play slots in the real money mode for free.
You can win real money prizes and cash them out after meeting the wagering requirements:
A casino deposit bonus is also called a match bonus, which matches your deposit amount by a certain percentage.
For example, if you claim a 100% match bonus, the online casino doubles your deposit amount as a bonus.
If you deposited $20, you will get a bonus of $20, making it a total of $40 in your account:
These are free spins you must make a deposit to claim.
The upside is that you receive more far free spins with more favourable bonus terms:
A match bonus combined with a free spins offer creates an attractive welcome package because it gives you the best value for your money.
Some online casinos spread these bonuses over several deposits:
100% Up To £600 Match + 50 Free Spins On Kingdom of Cash

The obvious advantage here is that you don’t have to wager your winnings to cash them out - what you win is yours to keep!
Many online casinos offer multi-tiered VIP programs with exclusive loyalty rewards like reload bonuses, free spins, and cashback deals.
Players who reach the higher rungs of the VIP ladder get perks like higher withdrawal limits, personal VIP hosts, higher betting limits, faster payouts, and priority customer support.
Online casinos offering VIP Programs reward players with points for real money play. You need to collect the required number of points to reach a higher VIP tier and unlock the rewards associated with it.
You can also redeem points for bonus cash subject to low wagering requirements.
Online casinos offer better rates of point-to-cash redemption to players at the higher VIP levels:

Casino bonuses at UK online casinos have terms & conditions, which vary from casino to casino.
We strongly recommend reading the bonus T&Cs before claiming the bonus for the following reasons:
Read on to learn about the most important terms and conditions:
Wagering requirements prevent you from cashing out your winnings before playing through the bonus amount the required number of times.
They may apply to the bonus amount, the free spin winnings, or the bonus plus the qualifying deposit amount.
Online casinos express wagering requirements as multiplier values, denoting the number of times players must wager the bonus before requesting a cashout.
You cannot request a withdrawal when you have an active bonus. If you do so, the online casino will deduct the bonus wins from your gaming account and void the bonus offer.
Wagering requirements protect online casinos from bonus abuse and ensure fair bonus usage. They give players the satisfaction of earning their bonuses before requesting a cashout.
Here’s a wagering requirement applied to a no deposit bonus:
mfortune Casino offers a £10 no deposit bonus with a 20x wagering requirement. This means you must play an amount equivalent to 20 times your bonus.
Here’s a calculation that puts this into perspective:
So, once you’ve played £200, any remaining funds in your bonus balance are converted to real money and transferred to your cash balance. You can now withdraw your bonus winnings.
And here’s how they apply to no deposit free spins:
888 Casino offers 20 Free Spins on . These Free Spins come with a 30x wagering requirement.
Let’s assume you claim these Free Spins and win £10. This means you must wager £300 to convert the Free Spins winnings to real money you can withdraw.
Here’s a calculation that puts this into perspective:
So, once you’ve played £300, any remaining funds in your bonus balance are converted to real money and transferred to your cash balance. You can now withdraw your Free Spins winnings.
When you claim a match bonus, the wagering requirement may apply to both your bonus and the deposit you made to claim it.
See this example:
Blood Moon Casino offers a 400% Up To £800 match bonus with a 45x wagering requirement. This means you must play an amount equivalent to 45 times your bonus.
So, if you deposit £10 to claim this bonus you must wager play £1125 to convert the bonus funds to real money you can withdraw.
Here’s a calculation that puts this into perspective:
So, once you’ve played £1125, any remaining funds in your bonus balance are converted to real money and transferred to your cash balance. You can now withdraw your bonus winnings.
Win caps help online casinos profit from their bonus offers by preventing you from cashing out all your bonus wins.
For example, if you claim a bonus with a win cap of $50, you can cash out only $50 from your bonus wins even if you have won more.
Win caps range from £10 to £200 at most online casinos. Usually, they apply to no deposit bonuses. Deposit match bonuses either have no win caps or very high win caps.
Since all wins area multiplciations of your stake, you can win massive amounts if you make big bets.
Online casinos do not want you to win too much money while using your bonus.. Therefore, they limit the amount you can bet per round or spin. Usually, you’ll be limited to playing £5 per spin or hand.
Online casinos reserve the right to void your bonus if your bet exceeds the bet size limit.
You cannot use your bonus on any game of your choice because casinos exclude high variance slots and games with high return to player (RTP) percentage from their bonus offers. The purpose is to limit your chances of winning big amounts.
A list of eligible slots is available in the bonus T&Cs section. We suggest reading them to ensure that the online casino does not exclude your favorite games.
Casino bonuses have expiry dates. They turn invalid after a few days or weeks or months, depending on the online casino offering them.
You need to clear your bonus before it expires, failing which you will lose your bonus winnings. Check the bonus terms for expiry dates to ensure that you have enough time to clear your bonus.
Game weighting percentages refer to the percentage of your stake amount contributing towards meeting the bonus wagering requirement.
For example, slots have a 100% game weighting percentage at most online casinos. If you wager $100 on slots, $100 counts towards the wagering requirement.
On the other hand, if you wager $100 on a 10%-weighted blackjack game, only $10 contributes towards the wagering reqruiement. Slots are usually 100%-wieghted whil other games range from 0% to 20% depending on which casino you’re playing with.
We choose UK casino bonus sites carefully. We pick only online casinos licensed by the UK Gambling Commission, preferring online casinos that prioritize safety, security, fair gaming, and responsible gambling.
