A casino promo code, or casino bonus code, is exactly what it sounds like.
They work the same as how you'd input a promo code to get money off a Deliveroo order or when shopping online, giving you access to an exclusive deal.
Instead of getting money off, though, the casino promo codes usually reward you with free spins on selected slots or give you access to a deposit match bonus when you place your first deposit.
You'll usually have to input the casino promo code during the sign-up process to ensure that you qualify for the relevant bonus.
While some offers mention a casino promo code in the terms, most online casinos these days automatically apply bonuses, with no code required.
In many cases, the welcome offer is activated automatically as part of the deposit process, making things quicker and easier for everyone.
That said, as this page proves, promo codes haven't entirely been made extinct. Some casinos still use them for exclusive deals, limited-time offers, or special promotions.
If a code is required, you'll usually need to enter it either during registration or at the point of deposit.
Whether you're using a code or not, most casino bonuses require qualifying deposits to unlock. A £10 minimum deposit is common across UK sites, which makes it easy to claim many welcome offers without committing too much upfront.
Don't limit yourself to offers with codes – if a promo code is needed, simply copy and paste it exactly as shown to avoid missing out.
Over the years, the team here at Hideous Slots have played at and reviewed over 200 casinos – so we've literally seen it all.

As always, all of our recommended sites are fully licensed and regulated by the UK Gambling Commission, which is the gold standard when it comes to safety, fairness, and security in the UK.
When new players sign up to MrQ using our exclusive link, you'll get to use the promo code POTS200 to immediately get credited with 200 free spins on Games Global partner Gameburger Studios' slot, Fishin' BIGGER Pots of Gold. The best part is that there are no wagering requirements attached to any winnings!
Using the code BETGETCASINO, new players who sign up, deposit, and wager £20 on any games on Midnite‘s casino can grab 100 free spins on Reel Kingdom's Big Bass Splash. These spins are valued at 10p per spin, with no wagering required on winnings and seven days to use them up, which is ample time.
If you're a new player signing up to NRG.Bet using our exclusive link, you can use the code nrg80 alongside your first deposit. To claim the free spins offer, you must wager £25 on any Big Bass Bonanza slots. Winnings do come with 10x wagering requirements, which is something to keep in mind.

Casino promo codes can be used to unlock exclusive bonuses, welcome offers, and other special rewards, but sometimes, they aren't as straightforward and clear-cut as they seem.
Before copying and pasting your next casino bonus codes, it's worth understanding the potential advantages and drawbacks of going for this type of casino bonus.
There is no right or wrong answer – it just boils down to your own preferences as a player.
Here's a quick breakdown of the pros and cons to help you decide whether using a casino promo code is right for you.
UK casino bonus codes are a simple and effective way to quickly unlock extra value, whether that's welcome offers, bonus spins, or exclusive promotions.
When used correctly, they can often stretch your bankroll and give you more playtime for the same deposit.
However, they are somewhat of a unicorn these days, since most casino offers are activated automatically or after opting in, as opposed to manually inputting a deposit code.
Still, this page has listed all our favourite casino promo codes currently available this month, offering lucrative bonuses well worth claiming.
Just keep in mind that, like any other casino promotion, promo codes come with wagering requirements and specific terms that need to be followed to the letter. A quick read of the T&Cs before claiming can prevent you from tearing your hair out later on.
All of the recommended casinos on this page are fully licensed by the UK Gambling Commission, guaranteeing you a secure experience, with other benefits like 24/7 customer support, trusted payment methods, and a great variety of games.
If you choose to play at any of our recommended casinos, remember to gamble responsibly.
Casino promo codes sometimes need to be entered when signing up to a new site or before making a deposit to unlock a specific casino bonus.
Yes, as long as you're playing at a UKGC-licensed casino and are using promo codes from a reputable source (like ours). We advise always checking the site's T&Cs before claiming.
Not always. Many UK casinos in 2026 automatically apply welcome bonuses, but some exclusive or limited-time offers will require a valid promo code.
Most UK casino promo codes are entered during registration or at the deposit stage. Always enter the code exactly as it appears to ensure it activates correctly.
Yes, many UK casinos will offer reload bonus codes, cashback promos, or seasonal offers tailored specifically for existing customers.
Most of the time, yes. However, new UKGC laws state the maximum for wagering requirements is capped at 10x, which means you'll need to play through your deposit or bonus ten times before being able to withdraw.
The best promo codes at the moment include Midnite with code BETGETCASINO, which gives players 100 free spins on Big Bass Splash, and MrQ with POTS200, with 200 no-wagering free spins on Fishin' BIGGER Pots of Gold.
