How to Use Claim Codes?
Using UK casino codes is simple. Follow these steps:
- Select a Casino – Pick a site from our best UK online casino promo codes list.
- Enter the Code – Use the relevant sign-up code when registering.
- Make a Deposit – Ensure your deposit meets the casino’s minimum requirement.
- Claim the Bonus – Your bonus funds and free spins will be credited.
- Meet Wagering Requirements – Fulfill wagering conditions before cashing out.
For example, Spin & Win Casino offers a welcome bonus worth 100% up to £500. You need to enter the promo code when you open your online account. The minimum deposit is £10. Clear your bonus funds within 7 days by meeting the wagering conditions (40x deposit + bonus). For example, that means you’d have to gamble £40,000 (40 x £500+£500) before releasing your free £500.
What are no deposit casino bonus codes?
No deposit casino codes are promo codes that give you free spins or bonus cash without needing to make a deposit first. They’re ideal if you want to try out a new UK casino without risking your own money. Just register, enter the code (if needed), and the freebie is added to your account. A good example? 888casino often gives out £88 free play with no deposit required.
| No Deposit Casino | Offer Code | Wagering |
|---|---|---|
| MadSlots | 100 Free Spins on Slots. No promo code needed during registration, spins valid for 7 days. | 40x |

| Luck Casino | 100 Bonus Spins. No deposit promo code is optional, valid on slots | 40x |
| Netbet Casino UK | 25 No Deposit Free Spins | 40x |
Are there casino promo codes for existing customers?
Yes — but they’re a bit more hidden. While most big bonuses are aimed at new players, many UK casinos do offer ongoing promo codes for regulars. These might unlock free spins on the “Game of the Week,” reload bonuses, or special cashback deals. For example, The Vic Casino has used code LIVE20 for an exclusive live roulette bonus for returning players.
Retention bonuses help to keep regular players happy but generally aren’t as large as welcome bonuses. In addition, ongoing casino bonuses tend to be targeted towards specific games such as slots and roulette.
You will need to opt in to the bonus via the cashier page. Make a minimum qualifying deposit and use the promo code provided by the online casino or one of these newer casinos. You’ll find this in your email inbox or on the casino website.
For example, The Vic Casino offers a 100% deposit match bonus worth £20 when you use the existing user promo code LIVE20. This loyalty bonus is eligible on live roulette only.
What are coupon codes or voucher codes for online casinos?
They’re the same thing as promo codes — just different names. Coupon, voucher, or bonus codes are used when you sign up or deposit to unlock a specific casino offer. Think of it like a supermarket voucher: you type it in, and you get a little extra. For example, PlayOJO once had a kicker code like OJOKICK50 that gave new UK players 50 no-wager free spins on Book of Dead — no nonsense, no wagering.
What Are The Codes for Free Spins?
Some UK’s top online casinos, such as bet365 and Grosvenor offer free spins as part of their welcome bonus package. You may receive free spins straight from the off or after clearing a deposit bonus. Use free spins bonus code 365GMBLR to claim 50 rounds at bet365 UK casino. By the way, these spins have no wagering requirements, keep all your winnings. View more low wager casinos here.
Always check the terms and conditions before you decide to use a promo code. Free spins bonuses usually have some sort of wagering requirement attached. You may have to play through your free spins winnings 5-10 times before you release them. There may also be a limit on the amount you can convert to real cash at the end.
Game of the Week’ free spins, Reload bonuses, Prize giveaways and more gambling offers.
