Best Online Casino Bonus – UK

Explore the best online casino bonuses in the UK with this comprehensive table. It details top casinos like Rialto Casino, offering a 100% deposit bonus and 50 free spins, to Bet365 with bet-and-get free spins. Each entry highlights unique promotions like live casino bonuses, loyalty programs, and new customer offers.

bet365, Barz, Vic, Grosvenorcasinos, Ladbrokes are the best UK casino sites that offer their new players generous casino welcome bonuses. Try your luck at Rialto with their £100 deposit bonus accompanied by 50 Free Spins. Want more offers? Dream Vegas casino currently has a good sign-up bonus of up to £300 and an impressive 150 Free Spins. If simplicity is your preference, Grosvenor UK’s offer might just catch your fancy: deposit £20 and you’ll find yourself with a £50 casino bonus.

Gone are the days of prohibitive wagering requirements (the number of times you need to play a bonus before you can convert it into withdrawable cash) or a minimal number of Free Spins. Look for a gambling website that gives you a genuine chance of winning a decent amount for an initial deposit not exceeding £20.

Additionally, with many sites now having multiple sister-sites, you have a much greater chance of repeating these bonuses across several casinos. Finally, with more and more players looking to game-on-the-go, make sure the casino has a good App, or at least a quality mobile version.

More and more games are now being designed primarily for mobile versions, so there should be no drop-off in quality when playing on your device.

Best Games to Play with a Casino Bonus

Every casino welcome bonus allows certain games to contribute towards the playthrough total. Some games contribute more than others, so which are best?

Slots: Online slots usually contribute 100% towards the bonus amount. That’s because the RTP (Return to Player percentage) is normally lower on slots than it is on table games such as blackjack. View free spins bonuses for top slots with high RTP.

Choose your slots carefully and try to find games that have high payouts. Some very high-paying slots may be ineligible, so always check the terms and conditions page first.

Blackjack: If blackjack contributes towards a casino bonus, you’re in luck. Online blackjack traditionally has a low house edge. However, be wary of bonus abuse if you’re caught only placing very basic blackjack wagers.

Roulette: European Roulette and French Roulette have low house edges of 2.7% and 1.35% respectively. However, you may make your bonus ineligible if you only place even-money bets and no risky wagers at all.

Welcome Offer Types & Terms

Whenever you sign up with a casino for the first time, they will try and tempt you with some freebies; some cashback or Free Spins or matched initial deposit casino bonus, or all of the above! Some Welcome Offers play out over the first 3 deposits; others are just a one off.

Almost all casino bonuses and promotions have an expiry date on them; as a general rule, matched deposit bonuses will need to be used within 30 days and Free Spins within 7 days.

A “matched initial deposit” is the most common type of Welcome Bonus for new customers and means whatever amount you deposit into your account to start with, it will be matched by the casino, so you essentially have more money to play with. Some casinos offer 100%, others as much as 200%, so search around for the best offers. The next most important aspect is the wagering requirement.

So, you can claim a welcome bonus if you’re a new customer at a UK online casino. You can only opt in to a welcome bonus once at any one casino. Also,remember, that you must be resident in the UK and have a validated casino account.  

Deposit Match Bonus

Many casino welcome bonuses feature a deposit match bonus. The bonus may be offered in one hit or split into two or three separate deposits.

Example: You sign up and claim a 100% deposit match bonus worth up to £500. The casino will match your first deposit with an equal amount of bonus cash. You may have to enter a promo code during the sign-up process to claim the bonus too.

Your bonus funds sit in your account until you successfully clear them by playing eligible games such as online slots and roulette. You’ll also have a strict time limit within which to clear the funds.

Free Spins

Some UK online casinos also include free spins in their welcome bonuses. You receive free games to use on a selected slot after you’ve opened your account. You can keep your winnings as long as you meet the wagering requirements. Some free spins bonuses will limit the amount you can claim on your free spins winnings. View the list of the best no deposit casinos here.

Example: An online casino offers 50 free spins on a nominated slot, with spins costing 20p per go. You win £20 on your free spins and must clear the set wagering requirement of 20x before you release your winnings. That means you’ll have to bet £400 (£20 x 20) before unlocking any free cash.

Wagering Requirements and Contribution Rates

Wagering terms are strictly set by the online casino. These relate to the amount you must bet in order to release winnings and bonus funds.

The playthrough requirement usually applies to the size of the deposit only or the deposit plus bonus. Wagering requirements are also applicable to free spins, though some free spins deals may carry no terms and conditions.  

Most deposit match bonuses carry strict game contribution rates. That means some games will contribute more than others towards the bonus total.

For example, imagine you receive £500 in bonus funds to play on slots and games. A typical list of game contribution rates may look like this: All slots: 100%, Roulette: 20%, Blackjack: 20%, Craps: 5%, Video poker: 5%, All other games: 0%.

That means that all slots play would go towards clearing the bonus total. However, only 20p per £1 would contribute from your roulette play, and 5p in the pound for craps play.

Minimal Risk Wagering and Convertible Rate

Bonus abuse is taken seriously by online casinos. A casino may void your welcome bonus if they suspect you of using minimal-risk wagering. This can include only placing even-money bets in roulette (e.g. Red and Black) or playing a lot of low-edge games such as Classic Blackjack.

Some casinos will impose a maximum convertible rate on their welcome bonuses. For example, a casino welcome bonus may carry a 5x max conversion rate.

Imagine you sign up for a 100% welcome bonus worth up to £200 with a 20x wagering requirement. You deposit £200 and receive £200 in bonus funds. You’d have to gamble £4,000 (£200 x 20) before releasing £200 in money. However, with a 5x convertible rate, you could only use your £200 to make £1,000 total.

How do I claim my casino promo?

Very easily. Some casinos will require a code to be used to claim any offer, but this is becoming much rarer. If needed, just cut and paste the code from any search engine or comparison website and simply input it when you make your first deposit. But, in most cases, you will be automatically allocated your Welcome Bonuses and Free Spins when you deposit. There is always a minimum qualifying deposit amount, usually £10 and almost never more than £20, but other than that, claiming your Welcome gift is very straightforward. 

How do I withdraw my casino winnings?

Once you have fulfilled any wagering requirements, your winnings will automatically become available to you and you can click on “withdraw”. With more and more casinos employing the Speedy Payments system, these funds will often be in your bank account within 15 minutes. 

What is a bonus wagering rules ?

This is the amount of times a bonus has to be played, via slots, video games or table games, before you can withdraw it as cash winnings. So, a 35x wagering requirement means that the bonus must go through at least 35 spins on a slot or table deal before it becomes “yours”. The lower the wagering requirement, the better. One of the advantages of the current competitive market is that wagering requirements are lowering across the board. All this means more cash for you to play with. Indeed, more and more casinos are advertising their bonuses have no wagering requirements at all, which means you get to keep whatever you win after just one spin!
