Top 5 UK Bonus Casinos for December 2024

Online casinos today are constantly trying to outshine their competitors by offering the most sought-after promotions. As a result, it’s very hard as a player to know which are the best casino bonuses and where to claim them.

We’ve therefore done the hard work for you and chosen our current top five casinos for bonus offers in the UK:

Rating Casino Claim
🏆 Overall top UK bonus casino 32Red Get Bonus
💰 Best first deposit casino bonus Spin Station Get Bonus
🎁 Best no deposit casino bonus Fun Casino Get Bonus
🤩 Best low wagering casino bonus MagicRed Get Bonus
🎰 Best free spins bonus Winomania Get Bonus

Types of Casino Bonuses

If the idea of an online casino bonus offer seems too good to be true, it's worth examining the logic behind it. There are more than a hundred licensed gambling sites vying for your business in the UK. To attract players and keep them happy, casinos give out big bonuses. They can afford to do this because they aren't paying the high overheads of a physical casino.

The best bonus casino sites will offer:

Welcome Bonus

  • Take advantage of a casino sign-up bonus and enjoy additional bonus funds on top of your initial deposit
  • This is usually done as a specified percentage of your deposit and might be spread out across your first few transactions, or simply apply to your first deposit. For example, Mr Mega offers new players a 100% up to £50 first deposit bonus
  • To claim the casino welcome bonus, you may need to accept it when making your first deposit or by using a specific welcome code

No Deposit Bonuses

  • Players can claim free cash or free spins without a deposit. Be aware that no deposit bonuses often carry steep wagering requirements
  • You'll usually only get a few pounds or spins with a no deposit bonus, but you can still use it to win real money
  • You may be required to enter a no deposit bonus code and/or register an account to claim

Reload Bonuses

  • Casino reload bonuses are for existing players and reward you for making more deposits by matching your deposit amount up to a specific percentage or giving you free spins or cashback
  • Most sites offer these for depositing on certain days or for special promotions
  • You many need to enter an online casino bonus code or click on a link from an email or social media to claim a casino reload bonus

Free Spins

  • As the name implies, this type of online casino bonus can be used on real money slot games for free
  • Some casinos dictate the game or developer you can use free spins promotions on
  • Free spins bonuses are either offered as standalone promotions or as part of welcome bonuses. For example, Duelz Casino’s welcome bonus includes a 100% up to £100 match bonus plus 100 free spins

Loyalty Rewards

  • Some casinos offer a loyalty programme to reward frequent players with points for every time you play or deposit. Points can be redeemed for cash or free play
  • Extra benefits can include prize draws, luxury travel and even a casino birthday bonus
  • High roller casinos automatically enrol you in their loyalty programme, so there's nothing extra you need to do to start earning rewards

Refer a Friend

  • As the name implies, you get rewarded when you refer a friend to your preferred online casino
  • Most casino sites pay out a set bonus when your friend signs up and makes a deposit
  • To claim this casino bonus, your friend will need to use a specific link you give them, or your personalised referral code

One of the main benefits of playing at an online casino is that the site will make it worth your while. Just in case endless fun and huge prizes aren't enough, you can get rewarded before taking your virtual seat by claiming a real money online casino bonus.

Frequently Asked Questions

How do deposit bonuses work?

When you claim a deposit bonus, you'll get extra cash on top of the money you’re adding to your bankroll. For example, you might claim a 100% deposit match bonus that will double the amount of your initial deposit.

Can I cash out my casino bonus?

While online casino bonuses are effectively free money, you can't withdraw your complimentary cash immediately. At an online casino, UK players must satisfy wagering requirements before cashing out.

Do I have to be a new player to claim a casino bonus in the UK?

While welcome bonuses are reserved for new players, the promotions don't end after your first deposit at an online casino. You can take advantage of casino reload bonuses, promotions and loyalty rewards after your initial deposit.

Can I claim bonuses on my smartphone or tablet?

It doesn't make a difference how you choose to access online casinos when it comes to getting bonuses. UK sites offer casino bonuses on iPad, iPhone, Windows Phone, Microsoft Surface and Android devices. Many casinos now also offer mobile-exclusive bonuses specifically designed for UK players who prefer to gamble on the go.

How do I find a great site with a big casino bonus?

Our gambling experts have tested and compared dozens of licensed casino sites in the UK. If you're ready to claim the best online casino bonuses, just visit any of the top-rated sites we've listed on this page.

What types of casino bonuses are there?

There are several types of online casino bonuses, from welcome bonuses that match your first deposit to loyalty programmes that reward you for playing and depositing funds. You can also get free spins and casino cashback bonuses at the best sites.

Are online casino bonuses worth it?

Top casino bonuses add extra value for players, but the terms and conditions can be confusing. That's why we explain them in our reviews and blacklist sites that don’t offer fair and reasonable promotions.

How long does it take to claim casino bonuses online?

You can claim most casino bonuses instantly, but computer systems and checks can mean that you'll need to wait 5 to 10 minutes for the free spins or bonus money to appear in your account. If it takes longer than that, it's best to contact customer support.

What are casino bonus codes?

While some bonuses are allocated to your account automatically, others need to be claimed with a specific code. This will be given to you on a casino site, or via email or social media. Simply input the casino bonus code when making your deposit to claim the offer.
