Summary of Casino Bonuses

Casinos create bonuses to encourage prospective users to register and place deposits. Casino bonuses are great for players to boost their bankroll, lengthen their gaming sessions, and enjoy testing out games using risk-free wagers. This page will cover everything from the different promo types and their benefits to how to claim a reward, how we rate different bonuses, and how to stay safe when claiming an online casino offer. 

Casino Bonus Types

Every player has their own preferences when it comes to online gambling and will seek out bonuses in line with them. Casinos will also build bonuses to suit different types of players—check out the most common bonus types below. 

New Player Bonuses

Almost every UK online casino offers a one-time new player bonus, which usually consists of a deposit match bonus, a batch of free spins or a combination of the two. 

Deposit Match 

A deposit match bonus is when a casino matches your deposit to a certain percentage, such as a 100% deposit match up to £200. They are the most common type of bonus available, offered by operators like WinOMania, LottoGo, Pub Casino, Barz, Luckster, Happy Tiger and 333 Casino. 

Deposit Bonus

A deposit bonus is any offer that requires a real money deposit, including free spins, deposit-matched cash, or even a combined casino and sportsbook bonus. Fafabet, for example, offers a 100% casino match bonus of up to £200 plus a £20 free bet, which is ideal for players who like to switch between casino and sports betting. 

Free Spins

Free spins are slot stakes with a predetermined value that are designed specifically for use on a single slot or a collection of slots. For instance, NRG Casino gives new players 80 free spins on Big Bass Bonanza when they wager £25 on slots. 

No Deposit

These bonuses don’t require a deposit but give new players a small amount of spins or bonus cash simply for creating an account. No deposit bonuses are lower in value and harder to find than deposit bonuses, but they do exist. Madslots currently gives every new player 100 no deposit free spins at registration. 

No Wagering

As the name suggests, no wager bonuses don’t have wagering requirements attached. Whatever winnings result from your bonus are yours to keep as cash (subject to any win caps). Hotstreak Casino currently offers 100 no-wagering free spins to players who wager £20 on slots, with winnings capped at £200. 

Existing Player Bonuses

After you play through your welcome bonus, there are plenty of reload offers waiting for you to claim at the top UK sites with the best casino bonuses. 

Reload Bonus

Reload bonuses are reserved for returning users who top up their accounts and place more deposits at their chosen online casino. However, they are typically less generous than new player offers. MadSlots offers a free spins reload bonus where returning players get 1 spin per £1 deposited (up to 200 free spins) every Sunday. 

Loyalty Bonus

Many online casinos offer loyalty schemes, VIP programs, or both to reward existing users. Offering exclusive monthly prizes like free spins, cashback, higher withdrawal limits and more, these bonuses are put in place to reward the casino’s most loyal players. 

Cashback

Cashback bonuses work by giving players back a percentage of their lost bets over a set period of time. For example, WinOMania has a weekly cashback promotion where players can earn up to 20% cashback on non-winning wagers every Monday. 

Advantages of a Casino Bonus

Bonuses are one of the key advantages that online casinos have over their brick-and-mortar counterparts. They offer numerous perks that every casino player can benefit from, no matter their budget, gaming preferences, or experience level. 

• Boosted bankroll: This one is obvious, but claiming a casino bonus can give you a sizable bankroll boost. Bigger bankroll = more chance to try games, have fun, and (hopefully) land wins. 
• Risk-free betting: Betting with bonus money or free spins is a great way for beginners to get to grips with game rules, slot features, bet limits and volatility without spending as much money. 
• Enhanced odds: Having a bigger budget means you can play for longer, potentially giving you a greater chance of hitting a winning spin or hand. 
• Increased enjoyment: Playing with bonus money means you can relax and enjoy the gameplay itself rather than worrying about losing as much of your hard-earned cash. 
• Loyalty rewards: Reload bonuses ensure returning bettors are kept rewarded. Claiming these bonuses can have long-term payoffs for loyal players, including cashback percentages and loyalty points. 

Being Careful with Casino Offers

Casino bonuses are alluring, but you shouldn’t take them at face value. Remember, the casino’s goal is to attract new players, not to dish out free money. Make sure to use bonuses responsibly and consider the following points before claiming one. 

Terms and Conditions

The T&Cs can make or break a casino bonus. UK players are often attracted by deceptively large bonuses that turn out to have unmeetable wagering requirements, short expiry dates or harsh win caps. As long as you choose a bonus based on its lenient T&Cs rather than the monetary value, you won’t get caught out. 

Wagering Requirements

Wagering requirements are the number of times you must wager a bonus before you can withdraw any winnings as cash. 35x is around the average wagering requirement in the UK, but they can be higher or lower depending on the casino. If a bonus has very high wagering requirements, it’s likely you’ll burn through your winnings trying to meet them. 

Time Limits

All good things must come to an end, and casino bonuses are no exception. While some have 14-day expiry windows, the more generous bonuses give you a month or longer to meet the wagering requirements. Be aware that while deposit-matched bonus cash usually has a long expiration, free spins tend to expire within 1-7 days of issue. 

Game Limits

It’s important to know which games you can wager your bonus on. Free spins bonuses are restricted to slots, but whether they’re limited to one slot or a broad selection can depend on the casino. Deposit-matched bonus cash is usually reserved for online slots, too, though some sites let you wager on table games or live dealer titles for a smaller wagering contribution. 

Win Caps

Win caps are the maximum amount you can win from a bonus. Though more commonly tied to no deposit offers, many casinos also attach them to deposit bonuses. A win cap can seriously restrict your potential to turn the bonus into real cash, so it’s important to check for them before depositing. 

How We Rate the Best UK Casino Bonuses

We undertake a thorough review process to ensure we only recommend the best casino bonuses for UK players. For a detailed list of our casino recommendations, check out our online casino page. 

Clarity for Players

You shouldn’t have to search high and low for clarity on what a bonus entails. The best casino bonuses label the stand-out T&Cs in their promotional banners so as not to mislead players about the offer. Instructions are explicitly clear about how to claim the bonus, how long you get to claim it, what games you can spend it on, and more.

Value of the Offer

Of course, you want to select a bonus that gives you the most bang for your buck. We believe the offers highlighted on this page provide the best possible value to players of all budgets. Whether it’s a generous package of free spins or a competitive deposit match amount, they give an excellent bankroll boost with fair, achievable terms. Other casinos may offer higher-value deposit matches, but more often than not, the conditions are costly to meet. 

Simple to Claim

We expect the process of claiming bonuses to be simple, with as few steps as possible. If there’s a promo code, it should be detailed clearly in the T&Cs. If not, the opt-in button should be obvious. For casino bonuses in the UK that are applied automatically, we expect them to be issued within 24 hours. Simple, straightforward and swift; these are the cornerstones of a good bonus. 

Fair Terms

As we’ve mentioned, the T&Cs are the most important element of a casino bonus in the UK. We want to see fair terms that enable players to have fun with their bonus rather than worrying about meeting overly strict conditions. The top casino offers on this page have achievable wagering requirements of 35x or under, high maximum win thresholds, decent expiry windows of 14+ days, low minimum deposits of £10 or less, and few ineligible payment methods.

Easy Withdrawal

If you manage to secure a win and meet the wagering requirements, the last thing you want is to have to jump through hoops to cash it out. We test out for ourselves exactly how long it takes for a casino to pay out bonus winnings and use this information to help decide on the best casino bonuses. Withdrawals should be as easy as heading to the Cashier, requesting a payout and receiving the money no more than a few days later.

How to Claim a UK Casino Offer

Using the Barz Casino welcome bonus as a prime example, we’ll show you exactly how to claim a UK casino promotion in the simple steps below:

1. Click the links on this UK casino bonuses page to head directly to the Barz Casino homepage. Then, hit the green “Sign Up” button to begin the registration process. 
2. First, add your name, email, date of birth, and country. On the next page, provide your phone number and address. Finally, create a username and password. 
3. Once your account is complete, Barz immediately gives you the option to fund your account. Remember to deposit £20 or more to claim the welcome bonus. 
4. Select your desired deposit method and amount, then confirm the transaction. The 150% deposit match up to £100 and 100 free spins will arrive in your account as soon as your deposit is processed. 
5. Finally, it’s time to spend your deposit-matched bonus funds on Barz Casino’s games. You can spend your 100 free spins on NetEnt’s popular Starburst slot. 

How UK Casino Bonuses Payout

When you’re ready to cash out your casino bonus winnings, you can pick from several secure payment methods at our top-rated online casinos, including: 

• Visa/Mastercard: Trusted and secure, both Visa and Mastercard payouts take 3-5 days on average. Debit cards are available for withdrawals, but the UKGC has banned credit card payouts. 

• Neteller: Neteller is a very popular e-wallet withdrawal option for UK bettors, offering rapid payout speeds and wide availability. The only downside is that Neteller is sometimes restricted from bonuses. 

• Skrill: Another popular e-wallet, Skrill is fast, accessible and doesn’t require you to enter your private banking details directly into the casino. However, like Neteller, Skrill deposits are sometimes excluded from bonuses. 

• PayPal: Like Neteller and Skrill, PayPal is one of the fastest payout options available, taking around an hour to land in your account after processing. It’s rarely excluded from bonuses and is almost always available at UK online casinos. 

• Bank transfer: Bank transfers are another popular withdrawal method for casino bonuses in the UK. They take a little longer to pay out than other methods (typically between 1-5 days) but have higher maximum withdrawal limits and aren’t excluded from bonuses.
