Since competition between online casinos for UK gamblers is massive, each casino tempts you with great casino bonuses.

On Sign Up

A good sign-up bonus needs to have two things: some free money or free spins to get you playing immediately after registration and good extra bonus money and bonus spins if you decide this online casino is worth your time and money.

Leo Vegas Casino has both covered and adds excellent mobile casino games in the mix, too, so you can enjoy the bonus package wherever you prefer to gamble. If you want to combine sports betting with a mobile casino gaming site, Leovegas is the best option with an enormous game selection.

  • 10 instant free spins on registration

Leovegas casino offers 10 free spins no deposit as a sign up bonus, followed by a welcome bonus up to £100 + 20 spins.

On The First Deposit

Out of all the casino sites offering first deposit casino bonuses in the UK, 21 Casino is among the best. Their first deposit bonus offer per player is 121% up to £300. Some casinos welcome new players with a bonus spread across multiple deposits; however, you only need to deposit once to claim this hefty casino bonus at 21 Casino. Claim the full first deposit bonus and play with £548!

Bonus Package On Several Deposits

Big bonuses used to be common at UK online casinos. Now in 2021, most bonuses tend to cater to the crowd depositing £100 or less, making sizable deposit bonuses a rarity. Besides Casino Rewards casinos, Dr slot also has an excellent big bonus for depositing players. Dr Slot’s massive 5-part bonus package hands you £1000:

  • 1st deposit: 300% up to £50

Dr Slot grants a hefty bonus package up to £1,000 over 5 deposits.

No Deposit Required

777 Casino offers a great no deposit casino bonus. You get a 77 free spins no deposit bonus on sign-up to play the popular Starburst slot game. Once you’ve cleared the 50x wagering requirement, you can withdraw your spin winnings.

If you prefer free bonus money, we recommend Pink Casino. This casino site offers its casino players £10 no deposit bonus funds for fun slots, instants and Slingo. Live casino and table games contribute less to the wagering requirement, but you can also play these exciting games with the no deposit offer.

Deposit Match Bonus Funds

Deposit bonuses are the biggest and most common casino promotion. They form the basis of almost all welcome packages. The deposit offers are tied to how much you deposit, calculated from the match-up percentage and limited by the maximum bonus amount.

So if the bonus is a 100% deposit bonus offer, your bonus will be the size of the qualifying deposit. Deposit match casino bonuses are also given to existing players, but then they are called reload bonuses.

No Deposit Bonus

A no deposit bonus is free spins or bonus money to play casino games for free with no deposit required. No deposit bonuses are perfect for testing real money casinos risk-free. You get free spins for adding a card, but most times, no card registration is needed.

UK casino players always get brilliant no deposit offers. We have listed new no deposit casinos 2021 for Britons to try out. New players may want to test a couple of casinos before making their 1st deposit. If you get a great experience with your free bonus and want to deposit, check out BonusFinder for the best first casino bonuses for depositing players in the UK.

Bonus Spins

If you enjoy playing slot machines, extra spins are the best casino promotion for you.

Often erroneously called free spins, bonus spins, or extra spins are real money spins you get when you deposit and are for selected games, typically online slots. They have the least terms and conditions (T&Cs) attached to them. What’s more, you often get bonus spins with deposit match bonuses. Typically, you’ll get the full number of spins with the minimum casino deposit. Extra spins are especially great for playing jackpot games. Get yourself a no wager bonus to keep what you win.

Existing Players: VIP and Loyalty Bonuses

As an existing customer, you also receive a wide variety of bonuses. Existing casino players get a wide variety of extra rewards as loyalty bonuses and via a VIP scheme. Most casinos run a loyalty program, where your real-money gaming accumulates VIP points. Mostly loyalty bonuses are extra free spins, deposit bonuses or a chance to exchange your loyalty points into cash. Their VIP scheme also treats VIP players with exclusive bonuses on top of the VIP customer service.

High Roller Bonuses

A high roller is a player with a big gambling budget who are looking to gamble with high stakes. We have a couple of exclusive casino bonus offers for big money games. Casino Rewards casinos grant perfect high roller bonuses. As a high roller, you’ll enjoy the Luxury Casino sign up bonus. They offer a £1,000 bonus over five deposits for high roller players.

Deposit Match Percentages

Deposit match bonuses come with varying match percentages and max bonus funds. While 100% deposit bonus offers are the most common, you can also find up to 500% deposit casino bonuses. The higher the percentage, the more you get with your real-money deposit amount. In turn, the max bonus amount varies between £25 and £500 in bonus cash funds. Even with a smaller bonus value from your deposit bonus offer, you have a chance for bonus winnings.

100% Bonus Genesis Casino
200% Bonus PocketWin
300% Bonus Dr Slot
400% Bonus Unibet
500% Bonus Coral Casino

A bonus code is a character combination you have to enter when making a deposit or register for a casino account if you want to be eligible for the bonus offer. You’ll find active bonus codes from our page, promotional emails, social media promotions, and advertisements on the casino’s website.

While players are keen to find bonus codes for UK casinos, a bonus code usually isn’t required for welcome bonuses. As a new player, you’ll often receive your bonus funds and spins without any promo code.

How to Use a Bonus Code

Here’s our step-by-step guide on how to claim a casino bonus using promo codes:

  1. Choose your favourite bonus and click a link from BonusFinder UK
  2. Sign-up the registration form
  3. If there is a code you need to use, it automatically fills in on the registration form. After that, you’re eligible to receive your sign-up bonus.
  4. Fill in the working code if it doesn’t fill in automatically.
  5. Finish the registration process and start playing.

In case the code you added doesn’t work, you can contact directly to your online casino’s customer support, and they will happily help you get your bonus money.

🧾 T&Cs: Terms and Conditions

Before you claim an online casino bonus, it is important you read the T&Cs attached to the bonus offer. In 2021, online casinos are always required to make their T&C’s very visible and easy to read. They are usually quite similar, but some differences make some bonuses worth it more than others.

We explain the most common terms & conditions casinos attach to their free spins, bonus money and other bonuses. For example, most often, bonuses exclude live casino games. While the rules don’t make it impossible to win, they limit what you can and can’t do while playing with your bonus.

Wagering requirements

The most common limitation attached to bonus offers is bonus wagering requirements. Wagering requirements dictate how many times you must wager your bonus before you can withdraw them. Both winning and losing rounds with bonus or bonus winnings count towards the wagering requirements. Most online casinos have wagering requirements of 40 to 50, but then there are low wagering casinos with wagering less than 30x and no wagering casinos with no wager bonus offers.

Once you have cleared your wagering requirements, your bonus wins are transferred to your real money balance. This balance is also called the deposit balance, where your deposits are. This balance is free from wagering requirements and can be withdrawn anytime.

Wagering Contributions

Even if the welcome bonus is not for selected games, it may still have varying game contributions. This term means that games contribute to the wagering requirements according to the game weightings. The varying game weighting requirements determine the qualifying slots and games and their wagering contributions.

If you want to play a specific game or type of game, make sure its game contribution is above 0%, preferably 100%. Bonus funds are separate to cash funds, and sometimes only bonus funds count towards wagering contribution. With a no wager bonus, you don’t need to care about wagering contributions.

Other Bonus Terms

Besides wagering requirements, other t&cs apply as well. Let’s run through the most typical restrictions and limits attached to a deposit bonus offer. When you know what t&cs to look for, you’ll indeed find the ultimate bonus and avoid any unpleasant surprises. This way, you’re guaranteed to enjoy playing your favourite casino game with a bonus and have a fantastic gaming experience.

Maximum Win

Always check the bonus terms and conditions since some online UK casino sites limit the amount you can win. Particularly if it’s a free spins bonus, there’s probably a max win attached. You should check if the spin winnings are credited as bonus or cash funds.

Minimum Deposit

Often, casinos attach a minimum deposit amount to every deposit bonus type they offer. You can get excellent match deposit bonus offers with a minimum deposit of £10, £20 or £50. These bonus deals could be even more valuable to you than some free spins no deposit casino promos! Check out our list of top minimum deposit casino sites in the UK.

Payment Method Restrictions

You might not be eligible for the bonuses with specific payment methods at real money casinos. E-wallets such as Skrill and Neteller are typically among the restricted deposit methods. Always make sure you can receive the bonus before you make a deposit.

Game Restrictions

Usually, there is a pre-chosen list of slots you can play with free spins and sometimes also deposit bonuses. Moreover, not all games count towards the wagering requirement, and not all games contribute equally to the wagering requirement.

Completely restricted games often include table games, video poker and sometimes also progressive jackpot slots. The game restrictions are primarily due to the high return to player (RTP) of these games.

Expiry

Be aware of the time limits and expiry. Most casinos require you to cash in your bonus and meet the wagering requirements in a specific time frame. Welcome bonuses are usually only available during your first week after registration, while for other bonus types, the time limits are usually 30 days.

Betting Limit

All casinos limit how much you can bet with your bonus funds. When playing with cash rewards, most of the time, the max bonus bet size is tied to your deposit (max bonus bet could be 10% of your deposit); sometimes, it’s a certain sum (“£5”). If you bet more, you’ll be in breach of t&cs and can’t get your bonus or spin winnings.

💡 Tip: Play Slots and Bet Small

If you’re not bothered about the finer points of terms & conditions, play slot games, stay under the maximum bet limit and realise not all slot games count the full 100% against the wagering requirement. You do need to remember that you can’t withdraw your bonus in real money right away.

We recommend trying, for example, Starburst, one of the most popular games from NetEnt, and Rainbow Riches, an Irish-themed old school slot from Barcrest. While not as frequent as Starburst free spins, you can get Rainbow Riches free spins from some UK online casino sites.
