Top Bonuses for Existing Players for September 2025

Understanding the Concept of Existing Player Bonuses

Existing player bonuses are casino promotions you receive when you are already a member of a specific UK casino. They are rare compared to welcome bonuses tailored for new customers. However, they might have higher values or have more lenient casino bonus terms.

Some gambling sites offer existing players bonuses for loyal customers or even those who haven’t been active in a while. Each website decides when to provide these types of promotions and what conditions you should meet to be eligible.

Some considerations are needed before you engage in this article because bonuses for existing players are used to keep the player loyal. Still, multiple UK casinos have two pillars of rewarding frequent customers. The first tool to do so is bonuses for registered customers, but VIP schemes make the second pillar.

You must understand that VIP schemes are different from bonuses for existing players because you must work to grab personal bonuses designed based on your playstyle. The most known VIP system is across Casino Reward gambling sites, where you have one VIP scheme across all sister casinos.

For example, suppose you’re a Yukon Gold, Grand Mondial Casino, or Zodiac Casino member. In that case, you will see that the VIP system is the same across all casinos, which is very professional and lucrative.

Existing players bonuses vs loyalty bonuses?

To be eligible for an existing player bonus, being signed for a while on an active account is enough. You don’t have to complete anything else to play with that offer. Loyalty bonuses require a history of constant sessions and, sometimes, a limit of spending that you have to get over. Loyalty bonuses are reserved for players who already are in a loyalty scheme at a certain level.

Another major difference comes from the frequency with which you can find them. Loyalty bonuses are planned and offered on a fixed scheme of spending while existing bonuses do not come constantly.

Outstanding Casinos Where You Find Bonuses for Existing Players

Our experts know that sometimes existing players are overlooked, and there are few promotions available for loyal gamblers. We tested the top online casinos in the UK, and we made a list of note-worthy reload bonuses.

Every day, existing players can log in and play a dedicated free game – no deposit required.  We found out that incentives include real funds and free spins, and winnings are credited directly to your balance with no wagering requirements.

In addition to the free game, Monopoly Casino occasionally introduces game-specific challenges or special tournaments.

Fafabet Casino – Best for Daily Existing Player Promotions

Fafabet Casino offers weekly slot tournaments tailored for returning players.

As an existing player who deposits regularly, you can get auto-enrolled in the special events, making it an easy way to earn extra incentives without opting in or joining a loyalty system.

If you play that game and meet the wager threshold, you’ll get bonus spins or entries into special raffles.

We were also impressed to see that numerous other promotions for existing users are available, such as Slot Masters tournaments, daily free games and even a refer-a-friend bonus. So, if you refer someone who meets a certain wagering condition, you’ll also get bonus funds to play with.

Pros

• Daily games and Game of the Week feature

If you’re on the leaderboard, you can get exclusive incentives, such as free rounds, bonus funds or many others.

Instead of fixed tiers, you receive bespoke incentives, like cashback offers, free spins, or reload bonuses, tailored to your playing style and frequency.

Pros

• Personalised loyalty programme
• Up to 8 daily tournaments

Both of them usually require minimum deposits of at least £20 and can grant up to £500 on deposit losses, which is a generous amount. Besides that, you can access an exclusive Wheel of Spins that offers free rounds on various games, the maximum number being 500 spins.

Pros

• Weekly cashback for returning members
• Game of the Week feature
• Exclusive holiday offers, such as Easter or Christmas

Cons

• No promotions for live dealer games

Free Spins for Existing Players 2025

Free spins with no deposit are the most popular type of UK bonus, so naturally, they are offered to existing players as well. Casinos create free spins for existing players no deposit UK offers to existing customers, and offer them batches of spins on slot games. Usually, these batches start at 20 spins and go up to 100 or 200 spins in one offer.

There are 3 ways in which you can claim free spin bonuses for existing customers:

1. Bookmark this page to see the casinos you’re signed up at and their new bonuses. We show you how to claim each individual bonus and our expert rating of it.
2. You will find the new bonuses in the promotional materials the casino sends you via email or SMS if you’ve agreed to receive such information on your account.
3. Casino representatives contact you via live chat and give you the bonus on your account. Even though we have seen this happen a few times, such cases are rare.

Otherwise, claiming is much simpler if you’re already signed up. Just pick the bonus while logged in to your account, activate it with a code (when needed), and you can start playing.

KCB’s Selecting Method for Existing Customer Deposit Bonuses

When evaluating existing customer deposit bonuses, we focus on several key factors to ensure you get the best value. Our approach is transparent, and we use a set of specific criteria to determine which bonuses stand out:

1. Wagering Requirements: We prioritise bonuses with lower wagering requirements because they make it easier for you to withdraw your winnings. A bonus with a 30x requirement is more favourable than one with 50x or more. We will always aim to choose non-difficult ongoing promos for you.
2. Bonus Amounts: Our goal is to find bonuses that suit different budgets and playing styles. For example, between a bonus of 50% up to £20 and 100 free spins with £10 minimum deposit, we will always choose to show you the one with a higher value, like those 100 free spins, because they will help you spend more time playing your favourite slot.
3. Game Eligibility: Not all bonuses are created equal when it comes to where you can use them. We select only those offers where you can play multiple games, but when we see a high-quality bonus with one game availability, we will also list it.
4. Time Limits: At KingCasinoBonus, we don’t appreciate a low bonus lifetime of 24 hours. On the contrary, we select bonuses for existing players with time limits betwee seven days up to 30 because rushing things can lead to unwanted outcomes.

Weekly Casino Regular Promotions to Know

Yet, some websites also offer special incentives, such as weekly spins of a bonus wheel, prize twister or other special promotional features.

Weekly free spins for existing customers

For weekly free spins existing customers’ bonuses, your rollover during a week and participation in slot tournaments dictate the number of spins you get at the end of that week.

Payment Methods Available

What to choose, debit cards or e-wallets?

• Card payments are better if you deposit large sums.
• Pay by Phone casinos are suited to infrequent players and low depositors.
• Cash depositors have a way to pay with Paysafe.
• E-wallet transfers are recommended if looking for an under-1-hour withdrawal casino.
• Choose PayPal UK casinos for the largest cashout limit and payouts in less than 1 day.

Most of the time, when it comes to gambling, it is better to take the safe route. So, for existing player bonuses, popular services like Visa, Mastercard, or PayPal are the most useful. As far as we’ve seen through our analysis, only 4.5% of cases have any glitches or issues when using these payment methods.

On the speed feature, e-wallets and online services are still the top choices. Skrill, Neteller, Apple Pay and PayForIt are still the best. The transaction speed on these is, on average, 230% higher than bank cards. However, you need to read carefully each bonus description we provide. Sometimes, these e-wallets are incompatible with your bonus.

One trendy option is Pay By Phone if the offer requires a deposit under £30. UK players use it more frequently, and your deposit will be charged on your phone plan. Regardless of your payment, always be aware of the possibly hidden fees and the waiting times needed. Make sure to stick to your budget and play safe!
