Best online casinos with bonus codes in the UK
What is a casino bonus code?
If you’ve been in the online casino world or the iGaming industry for a while, you’ve likely already claimed a bonus. As you may recall, these offer exciting rewards for your account, usually in the form of extra funds, free spins, and many other perks.
Well, there’s another way to activate bonuses, and that’s through casino bonus codes. By entering a bonus code when making a deposit—since this is the main method of activating any offer—you can instantly unlock the associated promotion.
Since there are already public bonuses that you can claim directly, you might wonder why you should use casino bonus codes. The reason is simple: these offers are completely premium, often providing better rewards than standard bonuses.
How to get a casino bonus code in 2025?
One of the best things about casino bonus codes is how easy they are to access. Whether through your email, social media, or even directly on the platform, you’ll always have them at your fingertips for a successful activation. Here’s a step-by-step guide to help you out:
- Find a casino that supports bonus codes. We have plenty of recommendations, but choose the one that feels safest and most convenient for you.
- Sign up at your preferred online casino. The registration process is usually quick, requiring just a few details to create your account.
- Take part in casino bonus code campaigns. During special promotions, you’ll find a range of offers, including exclusive bonus codes you should grab whenever possible.
- Subscribe to the platform’s newsletter. This way, you can receive casino promo codes directly to your email.
- Follow the casino on social media. Another effortless way to get access to the latest promo codes.
It’s that simple! With the variety of sources where a casino can distribute promo codes, they will naturally come your way. However, keep in mind that not all casinos follow these same standards, so some may not offer every method mentioned above.
Types of casino bonus codes
Since every casino bonus code comes with its own bonus, it’s no surprise that there are different types of bonus codes available. These can vary not only in their rewards but also in how they are activated or obtained. Here’s a breakdown of the most common ones:
Welcome bonus codes
Welcome or sign-up bonuses are the perfect offers for new players, often being the first promotion they can claim, with generous rewards. Many of these bonuses require a casino bonus code for activation, which is usually publicly available on the platform where you register.
Even though it’s a welcome bonus, and just like the original offer, these codes can only be used once per player—regardless of whether a new welcome bonus is introduced later. Despite this limitation, the offer typically lasts long enough to fully make up for it.
No deposit bonus codes
On the other hand, a no deposit bonus code allows you to skip the requirement of making a payment to claim the bonus. It works just like regular bonuses, but you can activate it at almost any time from your account while enjoying similar benefits.
That said, don’t expect massive amounts—after all, it’s a free offer, which comes with both advantages and limitations. However, the terms and conditions (T&Cs) of these offers are usually among the most flexible, balancing out the fact that their rewards aren’t as high as deposit-based bonuses.
Deposit bonus codes
As you might expect, deposit bonus codes require an investment from you to activate. A minimum deposit amount must be added to your account before you can claim the offer. Depending on the casino, your rewards may be credited instantly or released over a fixed number of days.
Since a deposit is required, the rewards tend to be larger than those from a no deposit bonus code, and they can last longer—sometimes even weeks rather than just a single bet. The minimum deposit amount needed is usually quite low, often ranging between £10 and £20.
Free spins bonus codes
Instead of opting for extra funds in your account, you have the option to use casino bonus codes that grant free spins. These, in simple terms, allow you to play selected casino games for free, which may include slots, table games, and even live casino titles.
The biggest advantage of using free spins over a standard bonus fund is the sheer number of spins you can receive—ranging from 100 to 300 free spins. The bet amount per spin is fixed, but since they can often be used on games like progressive jackpots or feature-buy slots, their potential value is significant.
Cashback bonus codes
This type of bonus code is relatively rare, but we’ve encountered it firsthand in previous experiences. Instead of awarding bonus funds or free spins, cashback bonus codes refund a percentage of your losses over the course of a week, allowing you to keep playing for longer.
Cashback offers could be considered part of the no deposit bonus category since they only require you to enter a casino bonus code to activate them—without needing to make a deposit. However, the main condition is that you must play consistently at the casino offering the deal, usually around five days per week. If you meet this requirement, you can be sure that a portion of your losses will be returned as guaranteed funds.
Exclusive bonus codes
Many casino bonus codes are for one-time use only, especially when they are released for special events or seasonal promotions. Once their validity period expires, you likely won’t see them again, and there’s no guarantee they will return next year.
These codes are limited for a reason—they offer enhanced bonuses compared to standard casino promotions. Whether they boost cash rewards, free spins, or cashback, they rank among the best offers available. It’s always worth trying to activate them, as missing out on these exclusive opportunities can be a real loss.
Bonus codes for Plinko
If you’re a fan of the popular Plinko game, you’ll be pleased to know that some casinos offer exclusive bonus codes specifically for this exciting title. These codes can grant you extra funds or free spins that can only be used in Plinko, giving you a great chance to maximise your winnings while enjoying one of the most entertaining games available.
Plinko casino bonus codes are typically available during special campaigns or as part of exclusive promotions from select casinos. Be sure to check the terms and conditions, such as wagering requirements and expiration dates, to make the most of this offer and enhance your gaming experience.
Bonus codes for casino: Terms and conditions
Activating a casino promo code is as simple as entering it when making a deposit. However, like any bonus, there are several important terms you need to be aware of. Otherwise, you might run into unexpected surprises when trying to use them.
But don’t worry—most of these conditions won’t reduce the potential of your promo code, but rather define how you can use it. Below, we explain the key requirements you should know before activating any casino bonus code, so read carefully!
- Wagering requirements (Rollover): Bonuses wouldn’t be much use if you couldn’t keep your winnings! Thankfully, you can, but you’ll need to wager the initial bonus amount a certain number of times before withdrawing. The specific wagering requirement will always be outlined in the casino’s terms and conditions.
- Expiration dates: Every casino promo code and its associated bonuses come with a time limit. Typically, the validity period ranges from one to two weeks, though some may last up to a month. Plan your gameplay accordingly so you don’t miss out on your rewards.
- Game restrictions: Certain games or even entire game categories may be excluded from specific promo codes. This is an important detail to check at your chosen casino, as ignoring it could significantly limit how you use your bonus.
- Betting limits: Both casino promo code and free spins often come with fixed betting limits. If you place bets outside of this range, you could face penalties for violating the casino’s terms and conditions. Once again, it’s crucial to understand these limits before playing.
- Maximum winnings: Finally, just like betting limits, there are usually caps on the total amount you can win from promo code rewards. Fortunately, these limits tend to be quite high, meaning it would take an exceptional amount of luck to exceed them.

Which UK casinos offer casino bonus codes?
In this guide, we’ve listed all the casinos that provide the most exciting casino bonus codes available in the industry today. Of course, this list is constantly changing, so we encourage you to stay alert for new options that may appear.
Can casino bonus codes be used simultaneously?
No, this is not possible. If you try to enter one bonus code immediately after another, we do not recommend it either. The vast majority of casinos allow only one active bonus per user, meaning that if you haven’t fully used your existing bonus and activate a new one, any remaining funds from the previous bonus will be automatically lost.
Are casino bonus codes available for mobile users?
Yes! Most casino apps aim to include all their features, including the ability to use casino bonus codes. Just like on a PC, you’ll find a section to enter bonus codes when making a deposit. Make sure to type it correctly!
Where can I find the latest casino bonus codes?
If you’re already registered at a casino, your best option is to check its social media pages, as well as enable email notifications in your account settings to receive bonus codes directly. If you’re struggling to find the latest codes, you can always rely on our regularly updated list.
