Casino bonuses are promotional offers designed to attract new customers and reward existing players. They come in many forms — free spins, deposit bonuses, cashback offers and more — but they all work differently and understanding the terms is essential before claiming any offer.
This guide explains every type of casino bonus available to UK players, how each one works, and how to find the best value deals right now.
Key Facts
- Casino bonuses come in several types — free spins, deposit bonuses, cashback and no wagering offers
- Most bonuses have wagering requirements that you must complete before you can withdraw winnings
- No wagering bonuses offer the best value — the casino pays winnings as real cash immediately
- Casino Compare UK rates every offer for difficulty, risk and estimated value at casinocompare.uk
Types of Casino Bonus
Free spins
Free spins let you play a slot game for free. Winnings are usually paid as bonus funds subject to wagering requirements — though no wagering free spins pay winnings as real cash immediately. See our full guide to how free spins work
Deposit bonus
A deposit bonus matches a percentage of your deposit as bonus funds. For example, a 100% deposit bonus on a £50 deposit gives you £50 in bonus funds, taking your total to £100. These bonuses almost always have high wagering requirements and are harder to profit from than free spins offers.
No wagering bonus
The best type of casino bonus. You receive any winnings from a no wagering offer directly as real cash — no playthrough conditions required. See our full no wagering guide
Cashback bonus
A cashback offer refunds a percentage of your losses over a set period. For example, 20% cashback on losses up to £100 means if you lose £100, you get £20 back. Cashback is usually paid as bonus funds with wagering requirements, though some cashback offers pay in real cash.
Reload bonus
Casinos offer a reload bonus to existing customers when they make a subsequent deposit. Usually smaller than welcome bonuses but still worth claiming. Check the promotions page of any casino you are already registered with.
What Are Wagering Requirements?
Wagering requirements are the most important thing to understand about casino bonuses. They tell you how many times you must bet your bonus before you can withdraw any winnings from it.
For example, a £10 bonus with 10x wagering means you must wager £100 in total before withdrawing. Most players lose their bonus funds before completing this, which is why no wagering offers are so much better value.

How to Compare Casino Bonuses
When comparing casino bonuses, look at these factors in order of importance:
- Wagering requirements — lower is always better. Zero wagering is ideal, 20x or under is good, 40x+ is poor
- What the bonus pays — free spins winnings as real cash vs bonus funds makes a huge difference to actual value
- Time limits — how long you have to use the bonus and complete wagering. 7 days is tight, 30 days is comfortable
- Game restrictions — which games contribute to wagering requirements and which are restricted
- Maximum win cap — some bonuses cap how much you can win (e.g. £100 maximum from free spins)

Casino Bonus Terms to Watch Out For
- Bonus expiry — always check how long you have to use the bonus. Missing the deadline means forfeiting it
- Game contribution rates — slots usually contribute 100% to wagering but live casino and table games often contribute much less
- Maximum bet while wagering — most casinos restrict your maximum bet size while you have an active bonus (usually £5 per spin)
- Withdrawal restrictions — some casinos require you to complete wagering before you can withdraw even your original deposit
In particular, our step-by-step guides for each offer highlight all of these terms on Casino Compare UK.
Frequently Asked Questions
Can I claim a casino bonus more than once?
Welcome bonuses are for new customers only, and you can only claim them once per casino. However, existing customers can claim reload bonuses and ongoing promotions regularly. Check the promotions page of each casino you are registered with.
What happens if I withdraw before completing wagering?
If you withdraw your deposit or winnings before completing wagering requirements, you forfeit the bonus and any bonus winnings. Your original deposit is unaffected — you can withdraw that at any time in most cases, though some casinos do lock deposits until wagering is complete. Always check the terms.
Are casino bonuses worth claiming?
Yes — particularly no wagering and low wagering offers which give you a genuine positive expected value. High wagering deposit bonuses are harder to profit from but still worth claiming if you follow step-by-step guides. Start with easy casino offers
Do casino bonuses affect my ability to withdraw?
Only if you have an active bonus with wagering requirements. Once wagering is complete — or if you have no active bonus — you can withdraw freely. Some casinos let you forfeit an active bonus at any time to unlock withdrawals. Check the bonus terms for details.
Summary
Casino bonuses come in many forms but the principle is the same — the casino offers you something extra to sign up or keep playing. In particular, the best bonuses are no wagering free spins offers, where the casino pays winnings as real cash immediately.
Always check wagering requirements before claiming any bonus. Lower is always better — aim for 20x or under and prioritise no wagering offers wherever possible.
