Do UK Casinos Really Offer No Deposit Bonus Codes For Existing Players?

The term ‘no deposit bonus’ usually refers to a type of welcome bonus where you receive bonus credits or free spins in return for creating a new account. This type of no deposit bonus isn’t available to existing players.

However, existing players can receive regular bonuses and promotions that do not require a deposit.

If you are looking to receive regular no deposit offers, we recommend you consider the following tips:

Pick Casinos With Loyalty or VIP Programs

Many of the best online casinos have extensive loyalty rewards programs (LRPs) and VIP schemes.

These can be used to receive free spins and extra bonus credits in the following way:

  • Every time you make a deposit or wager, you earn Comp Points.
  • The more Comp Points you earn, the higher you climb in the Tier System.
  • Every time you reach a new Tier, you will receive new rewards and benefits.

Among the rewards and benefits of most LRPs are free spins and bonus credits. Furthermore, you may also get the opportunity to redeem your Comp Points for bonus credits and free spins in an online store.

While these rewards are not technically ‘free’ (because you need to wager real money), they are offered as an extra incentive. It is a great way to be rewarded for your loyal patronage.

Pick Casinos With Frequent Promotions

To retain loyal players, there are some casinos that release regular promotions. These promotions usually promote a new or popular title, or they are offered on a daily, weekly, or monthly basis as an extra incentive to keep playing.

This type of promotion will usually require you to make a real money deposit. They are therefore not like regular no deposit bonuses, but serve as an indication of a casino’s generosity.

The same casinos tend to reward you with free bonuses on special occasions - for example, to promote a new slot game, or to celebrate a significant date, such as your birthday or anniversary with the casino.

Winning Free Bonuses Through Slots Tournaments

Many casinos hold regular Tournaments that reward top-ranking players with free spins and/or bonus credits.

These Tournaments work in the following way:

  • The casino runs a Tournament to promote a specific slot game.
  • Players opt-in to the tournament and wager on the slot game.
  • A leaderboard will then rank the players by the amount they win on the eligible slot.
  • When the tournament ends, a prize-pool will be shared between the top-ranking players.

While they are rarely the top-prize, it’s common for certain players to receive bonus credits or free spins in their share of the prize-pool. Please remember that you will need to make an initial deposit to participate in the tournament.

Bonus Terms for No Deposit Casinos for Existing Players

All free spins and bonus credits are subject to a set of terms and conditions. It is essential you read and understand the T&Cs before you use your bonus.

Understanding the T&Cs will help you to:

  • Accurately compare the generosity of an online casino’s existing player promotions.
  • Avoid breaching the rules and losing your bonus.
  • Win real money using existing player free spins and bonus credits.

Wagering Requirement

Wagering requirements stipulate how many times you have to wager or ‘play through’ the value of your bonus before you can withdraw your winnings.

Wagering requirements are signified by a multiplier (for example, 10x). Therefore, if your bonus is worth £10, you would have to wager £100 (£10 x 10) using your bonus before you could cashout your bonus wins.

Casinos use wagering requirements to ensure that players do not claim a bonus and withdraw its value immediately - which is commonly known as ‘bonus abuse’. Casinos like to emphasise that it is a bonus they are offering, not free money.

By forcing players to ‘play through’ its value a number of times, casinos ensure that inauthentic players looking to abuse the bonus system are discouraged.

Wagering requirements can apply to the value of your bonus (in the case of bonus credits), the value of your free spins winnings, or the value of your bonus/free spins winnings plus the value of your deposit (in the case of a deposit bonus).

Example

Here is an example of how to work out wagering requirements:

BC.Game offers a £5 no deposit bonus with a 0x wagering requirement. This means you must play an amount equivalent to 0 times your bonus.

Here’s a calculation that puts this into perspective:

£5 bonus x a 0x wagering requirement = £ to wager.

So, once you’ve played £, 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

Casinos do not allow you to withdraw unlimited amounts using your casino bonus. Generally, you will be restricted to withdrawing between £10-£200 in real money using your bonus. Win Caps apply mainly to no deposit bonuses.

Bet Size Limits

There will be a maximum bet limit for every single bet you make using your bonus credits. This maximum bet limit tends to be set to around £5 per bet.

Casinos implement bet limits to make it more difficult to fulfill the wagering requirements. Without a maximum bet limit, you could go ‘all in’ a number of times and, if lucky, rapidly fulfill the wagering requirements.

Eligible Games

Every bonus comes with a list of eligible games. If you try to play any game not on the eligible games list you may lose your bonus. High RTP and high volatility games are excluded.

Please only play games on the eligible games list. This list applies to both your bonus (free spins and bonus credits) and winnings made from using your bonus.

Expiry Dates

No deposit bonuses come with an expiry date. Once you meet the expiry date your bonus and/or bonus winnings will be removed from your account and you will have to deposit to carry on playing. Most no deposit bonuses last between 2-7 days.

Please make sure you wager the entirety of your bonus immediately if you want to fulfill the wagering requirements.

Game Weighting Percentages

Game weighting percentages refer to how much of your stake contributes to the wagering requirements. Let’s use an example to illustrate what we mean by this.

Consider the following situation:

  • Slots (100%)
  • Table Games (4%)

In this example, we see that 100% of your stake on slots goes towards the wagering requirements. Therefore, if you bet £100 on a slot game, £100 will go towards the wagering requirements.

Alternatively, only 4% of your stake on table games will go towards the wagering requirements. Therefore, if you play a table game such as blackjack and bet £100, only £4 will go towards the wagering requirements.

This is why we generally recommend you play slot games using a no deposit bonus.

It is also worth noting that if you claim a deposit bonus, you will only start to fulfill the wagering requirements once you use your deposited funds. Game weighting percentages apple only when using bonus funds.

What To Expect From Our Recommended UK Online Live Casinos

Our job here at NoDeposit365.co.uk is to find the best casinos for every category, and make them easy to find. To guarantee that the casinos we feature are of the highest quality, we have designed an in-depth evaluation. Here’s an overview of the criteria we check for:

  • Licensing: Every casino must hold a UGKC license. This ensures they are regulated by strict laws designed to protect gamblers.
  • Games Library: A large games library with titles created by leading software providers is essential.
  • Banking Methods: We expect fast payouts and a diverse variety of banking methods for both deposits and withdrawals.
  • Terms and Conditions: Bonus terms should be fair and communicated in a transparent, easy-to-understand way.
  • Site Layout & Design: Content should be easy to find and the entire casino should be mobile-friendly.
  • Online Reputation: The casino should have a great reputation among former and current players on online casino forums.

FAQs

Yes, you can. However, please be aware that you can not claim the same no deposit bonus twice, nor can you claim more than one ‘welcome bonus’ at the same casino.

If you want to claim more than one no deposit bonus, here’s what you can do:

Yes, you can. To win real money with existing player no deposit bonuses, all you have to do is fulfill the terms and conditions. Once you do, you will be able to withdraw some of your bonus money.

Yes, they are! Mobile players are treated exactly the same as regular players who play on desktop and laptop. You can opt-in to a promotion, play your favourite casino games, and withdraw your winnings all from your mobile device.

For a list of the best online casinos for regular mobile players, please go to our list of the Best Gambling Sites With No Deposit Casino Bonus Codes For Existing Players.

All major mobile platforms are supported, including:

  • iOS
  • Android

It depends. More often than not, no deposit bonuses for regular players are superior to those offered to new players.

Casinos understand it is more profitable to keep an existing customer than to acquire a new customer. Because of this, they will treat regularly depositing players to superior bonuses and promotions.

However, the generosity of casinos can vary significantly. For the best deals, we recommend you sign up to a casino that features on our list of the Best Gambling Sites With No Deposit Casino Bonus Codes For Existing Players.

It’s unlikely. Most free spins offered to existing players are used to promote a popular slot or a new slot. Rarely will you be able to play any game, either with your free spins bonus, or with your free spin winnings.

For more information about which online casino games are eligible, please refer to our section on Eligible Games.

No, not always. Most online casinos will credit their no deposit casino bonuses automatically, or to any existing player that ‘opts-in’ to a no deposit promo. A no deposit bonus code is usually reserved for new players.

On average, they tend to last between 2-7 days. However, the validity of an existing player bonus can vary significantly. Please ensure you read the terms and conditions to find out how long your bonus lasts.
