How we tested each best casino bonus

Welcome bonuses are the best way to entice customers to an online casino site, with bonus funds or spins the most common offer amongst UK online casinos.

The best offers give users a high bonus amount from a small qualifying stake, with minimal wagering requirements needed before withdrawal.

We've tested all aspects of the UK's best casino bonus offers, compiling these into a comprehensive and up-to-date review of each.

Our experts utilised their years of experience within the UK casino scene to evaluate every part of what makes the casino bonuses listed throughout this piece the best the UK has to offer.

Bonus Amounts

Casino bonuses can come in many forms, with the most common of these being free bets, spins and bonus funds.

The bigger the bonus amount the better, with these providing players with risk-free funds to test out the games on offer with their casino site of choice without spending their own money.

We evaluate each of our casino’s bonus amounts carefully, holding them in comparison with all others out there, and regularly checking these to monitor any changes to the offers themselves, as well as the T&C's.

Qualifying Stake

A qualifying stake stake is the amount a player must either deposit or wager as their first bet in order to be eligible to claim their site's welcome bonus.

These often vary between sites, however most will only requiring you to bet/deposit £10 or £20 in order to claim their welcome bonus.

It's worth remembering that offers which have a lower qualifying stake may seem the better options as they're lower risk, however these are likely to return less bonus funds than offers that require you to deposit/stake greater amounts.

We assess each site's qualification stakes meticulously, whilst also taking into consideration the amount you're able to claim in the form of a bonus to make sure bettors know which offers are the best and why.

Regular comparisons are done between each and every single offer we evaluate, offering a comprehensive overview of the offer and the major positives that it brings.

Wagering Requirements

Most online casinos will have some form of wagering requirements included in their sign up offers. All this means is that any bonuses and/or winnings that come from their offer must be staked and re-staked a certain amount of times before you're able to withdraw.

These can vary from site to site, but for the most part the lower the wagering requirements the better, but this of course has to be held in comparison with the bonus amounts, with higher bonus amounts almost always equating to higher wagering requirements.

We stringently evaluate and test each of the wagering requirements of all our online casino sites, with most of this analysis being drawn from our personal experience, with first-hand knowledge informing everything we report on.

Terms and Conditions

An offer's terms and conditions is a very important part of casino bonus offers, with our team delving into all of these, explaining exactly what they mean to ensure users know all the important details before claiming each offer.

Every detail has been rigorously broken down, to ensure these are understood to the fullest extent. This is to help everyone ensure they claim their welcome bonuses in the easiest and most simple way possible.

About the Author - Tom Fuller

Online betting and casino sites have been my passion for seven years now, and during this time I've managed to accrue a huge amount of experience with casino offers.

This journey has been both enjoyable and enlightening, providing me with a plethora of knowledge and first-hand experience in regards to casino offers, something that means I know exactly what to look out for when judging an offer, as well as what a top-tier casino bonus should look like.

Every bit of this expertise has been combined into this analysis on the best casino bonus offers, as many rank as firm fan favourites, with some being outsiders that look worth taking a punt on.

Best Online Casino Bonuses Ranked

All British Casino

All British Casino (ABC) brings one of the most unique sign up offers out there and one that proves to be extremely valuable to players.

New customers are able to get their initial deposit matched up to £100, which means that if you deposit £100, All British Casino will give you an extra £100 on top of this in the form of bonus funds.

This amount is one of the highest bonus amounts around, with you struggling to find an offer that allows you to claim more.

All British Casino also allows players to claim 10% cashback on all of their losses, with this being actibed once a player's funds drop below £10.

This is a great way for players to get back into the game, with All British Casino giving them a portion of their losses back as cash.

Overall, ABC's welcome offer is comfortably one of the best out there, as it gives players not one, but two separate chances to claim bonus funds, with £100 being one of the most valuable deposit matches around.

Sky Vegas

Sky Vegas' sign up offer is truly fantastic, with two bonus offers combining into one, making it perfect for any and all types of player.

New customers will be rewarded with 50 free spins that can be used on a select set of games without needing to make a deposit, with these also coming with no wagering requirement.

This proves to be one of the best no-deposit offers out there, with users also then able to claim another 200 free spins by staking £10 on any Sky Vegas slot game.

The Sky Vegas offer proves to be excellent given this, as it allows players the opportunity to choose what type of rewards they want and tailor it to their own style of playing.

The 50 no-deposit free spins surpasses the likes of bet365, with the ability to then claim a further 200 off of just a £10 stake also proves to be great value.

250 free spins are one of the highest sets available to be claimed by players, and given this can be claimed from just £10, puts them well above most other casino offers in the UK.


BoyleSports casino's welcome offer is one of the strongest around, with new players able to claim a 500% bonus to use on slots from just a £10 stake.

The possibilities are almost endless with their £50 in free slots bets, with tonnes of games to choose from.

Users are given more than an ample amount of funds to try out loads of different slot games and find the one they enjoy the most.

This does come with a 40x wagering requirement, however this proves to be on-par given the bonus amount on offer with Boylesports' welcome bonus.

The maximum amount you can claim from this offer in the form of bonus funds is £50, whilst the max payout is £500, a strong amount for an offer of this ilk.

Sky Casino

Sky Casino, is essentially just another version of their Sky Vegas site, except for the fact that the latter places more of a focus on slots and other associated games, whilst the former combines both slots and the popular card and table games.

This results in their bonus offer being well worth checking out, with users being able to claim 100 free spins from just a £10 deposit.

The lack of any qualification stake is a handy aspect of this offer, as players do not have to risk their own funds in order to claim the bonus amount.

However, that is not the best aspect of this offer, this being the fact that there are absolutely no wagering requirements attached to any winnings. Yes, any winnings can be immediately withdrawn as real cash.

Virtually no other bonus offer on this list has no wagering requirements and we simply cannot understate how valuable this is. Winnings do not need to be risked again, and again increasing the chance of losing them.

Instead, any and all cash earned from the free spins can be withdrawn as real cash into players accounts. With few others offering a no wagering requirements free spins bonus offer the Sky Casino sign up bonus stands out.


Coral casino's welcome offer proves to be one of the strongest in terms of value users are able to claim.

New users can claim a £50 casino bonus from just a £10 stake, with you needing to wager this on slots in order to be eligible.

This means that Coral's welcome bonus returns a stake-to-bonus ratio of 500%, with this being one of the highest bonus amounts from offers that require with a £10 stake.

Very few other casino sites allow users to claim bonus funds of up to £50, with only the likes of Boylesports or All British Casino being able to match or beat this.

The bonus does come with a 40x wagering requirement, however this is par-for-the-course with offers of this standard, with Boylesports boasting the same wagering requirement for their offer.


Betfred's casino sign-up bonus proves to be generous on the whole, as it allows players to claim hundreds in free spins from just a £10 stake.

New users just need have to wager £10 on slots within the first seven days of creating their account in order to be eligible.

Users are then able to claim £10 worth of free spins, with players able to choose the denomination these come in.

Players can claim 200 5p spins, 50 x 20p spins or 100 x 10p spins, with the amounts of these all equating to £10 no matter which option you choose.

This makes Betfred's offer slightly more unique, as it gives players the freedom to choose how many free spins they want, as well as how much they want each free spin to be worth.

200 spins is one of the highest amounts of free spins out there, bettering the likes of bet365, with many competitors struggling to match this.


New users can claim 125 free spins with Betway casino's sign-up offer, with users needing to use these ‘Big Bass Bonanza’.

This can be claimed by staking just £10 on their casino games, vegas games or live casino tables.

The amount of free spins cannot be underestimated, with Betway providing their players with more than the total son offer with bet365 and BetVictor.

And whilst the free spins can only be used on one game, ‘Big Bass Bonanza’ is one of Betway's most popular games and boasts an RTP% of almost 97%, making it a great option when it comes to using free spins.

The best part of Betway's casino offer is the fact that your free spins don't come with any wagering requirements, meaning that any winnings won from these free spins can be withdrawn right away.

125 free spins definitely provides players with some serious potential, and only having to wager £10 to claim these only increases the quality of Betway's offer.


The secret to bet365’s casino welcome offer lies in its simplicity. Players can earn 100 free spins by wagering £10 on their eligible casino games when using the code ‘365GOAL’ at sign-up.

Players can choose whatever game they want to wager this £10 on, with only live slots and live casino out of the question, with users than able to use their 100 free spins on one of four slots that have been pre-selected by bet365.

This isn't the widest selection out there, however it's better than offers which forces users to play on one solitary slot.

No wagering requirements for these free spins is also a huge bonus, with users then able to withdraw any winnings won from these without needing to stake any more.

This offer is perfect for the casual player, as well as those looking to claim some free spins without having to wager much in the first place.


New players to Unibet simply have to deposit £10 in order to be able to claim £40 in free casino bonuses.

The bonus amount is impressively high and can open up some considerable casino betting opportunities for players.

It must be noted that the £10 in real cash will be utilised before the bonus funds and that this comes with a 50x wagering requirement.

For those users looking for a purely cash-based offer, this one stands out, with many returning either just free spins or a mixture of the two.

Quadrupling the initial stake for players is a great option for any player, but the wagering requirements must be taken note of here.


Grosvenor specialise in their casino offerings, and as such, offer one of the best online casino experiences in the UK right now.

A core part of this is in their bonus offer, such that new players are able to claim £30 in free casino funds when they deposit £20 into their account.

Users will need to them wagering their bonus amount and deposit amount (£50) before being able to withdraw winnings, however the wagering requirements for this are quite generous at only x30.

The maximum payout for this offer is also very strong at £2000, with most offers of this ilk only allowing players to win and withdraw up to £1000 at most.

The sheer simplicity and effortless methods by which players can get their bonus, sets the Grosvenor bonus offer head and shoulders above the rest in terms of ease of use.

Whilst others offer more in terms of bonus amount, the lack of frills or complicated steps, and of course the fact that players earn more than they deposit, places Grosvenor uniquely well on this list.

What are the best online casinos for deposit-match offers?

All British Casino's welcome offer is comfortably the best offer in the UK, as it allows users to claim a whopping £100 in bonus funds via the form of a deposit-match.

Few sites will let players approach close to £100 in bonus funds, with All British Casinos take this one step further with the cash back addition to their offer.

On top of their valuable deposit match offer, players can get 10% of all total losses back should their account balance drop below £10.

Providing players with some truly free funds on top of the deposit match truly sets ABC apart from the rest, and makes this two-fold bonus offer the best deposit match bonus around.

What are the best online casinos for free spins offers?

Sky Vegas takes up the mantle of having the best free spins offer in the UK thanks to their double-barrelled offer that offer 50 no-deposit free spins, as well as an extra 200 spins that can be claimed from a £10 stake.

Virtually no other online casino site gives away free spins for free, with the total amount of 250 spins on offer being one of the highest around, providing users with ample opportunity to explore a range of their slots games, and in turn, have more chances to win cash given these free spins don't come with any wagering requirements.

The sheer number of spins that Sky Vegas offers, as well as some of the fact that 50 of these don't even require you to make a deposit to claim, places them head and shoulders above their competitors when it comes to free spins welcome offers.

What are the best online casinos for bet-and-get offers?

BetVictor are the best in class when it comes to bet-and-get welcome offers, with new customers simply having to stake £10 in order to receive £30 in free casino bets, as well as 100 free spins.

The sheer range of opportunities provided to players by this bonus offer is what sets it apart, and well of course its inherent value.

BetVictor pencils in how and where these bonus funds can be used, with these needing to be spread across slots, live casino and live game shows.

This opens up new opportunities to customers, who may have previously not explored them with their own cash.

Of course, £30 and 100 free spins are both great sets of bonus funds, but it is how users are encouraged to spend them, and the experiences that come from this that sets the BetVictor offer apart.

What are the best online casinos for first-deposit offers?

Unibet sits atop of our best first deposit rankings, offering players a £40 casino bonus when they deposit £10.

This outclasses the likes of Grosvenor, who only provide their players with £30 in bonus funds.

The value here is clear, with players being able to kick off their playing with Unibet casino with £50 in their pocket, £40 of which is provided by Unibet themselves.

Users are not shoehorned into only being able to play on one area of Unibet’s casino, instead being able to experience loads of their offerings all without fear of risking their own cash.

What players are able to do with their bonus funds comes from the value provided to them, and the Unibet first deposit offer is comfortably one of the best out there.

What are the best online casinos for no deposit bonuses?

Sky Vegas are virtually one of the only casino's in the UK right now who have a no deposit bonus, and as such this stands them head and shoulders above the rest.

New users will be able to claim 50 completely free spins immediately after signing up. No deposit, staking or code is needed to be able to get the bonus spins.

Players can use these on a variety of games, and they come with absolutely no wagering requirements, allowing users to keep 100% of their winnings.

As one of the few no deposit casino bonuses in the UK, the Sky Vegas offer already stands out, even more so when considering the lack of nay wagering requirements.

Different Types of Online Casino Bonuses Explained

First Deposit

First-deposit offers are very easy to understand, with the amount you're able to claim being determined on the amount you first deposit after signing up.

Some of these are set amounts, such as ‘Deposit £10 and Get £30 in free casino funds and 50 free spins’.

Others offers prove to be more variable, with players earning more bonus funds with a greater first deposit.

These are often presented ‘Deposit between £10 or £20 and Get £30 or £40 in free casino funds and 50 or 100 free spins.

These represent a great opportunity for players as they require no initial risk of their own cash in order to earn these free casino bets or spins, with a simple deposit being all that is required.


These too are extremely valuable opportunities for new players, with them being able to claim casino bonuses without having to risk any real money.

The only difference is that the bonus funds are matched exactly to the first deposit made by players.

An example of a deposit-match offer may be ‘Deposit £20 Get £20 in free casino bonuses’, with certain casino sites offering free spins as an extra bonus on top of these, making them well worth keeping an eye out for.

The opportunity for any user to claim free bonus bets is particularly good as it is one of the few that do not require them to risk any of their own cash.

Free Spins

Free spins is an offer that allows players to claim free spins, with these either being issued as no-deposit free spins, or requiring users to stake a certain amount in order to claim them.

An example of a free spins offer will look like: ‘Deposit and Wager £10 on any casino games to receive 50 free spins’.

No-deposit offers will almost always come in the form of free spins as well, with users being gifted a certain number of spins for merely signing up, with players not required to deposit or stake certain amounts to get involved.

These are great for any customers who enjoy playing slot games, with most of these offers not having wagering requirements attached to them.


These are comfortably the most common type of casino bonus offers whereby players deposit and place a set amount and in return get bonus funds and or spins.

This generally comes in the form of something like ‘Stake £50 Get £100 + 50 Free Spins’, with players wagering a set amount of their cash in order to earn a casino bonus and spins.

Offers vary in initial wager and bonus amounts but will always return their users with more bonus funds than the deposit, sometimes offering a wealth of free bets for players to explore.

Best Casino Bonus Offers for Existing Customers

Most casino sites run some promotions for existing customers to enjoy that provide current players the chance to claim bonuses through frequent play.

Some online casinos have promotions for existing customers whilst others don’t, therefore players need to be aware of what is on offer and how it works before claiming.

Loyalty Bonuses

Loyalty bonuses are programs offered by casino sites that give users free bets or spins as rewards for playing with them consistently.

Players will usually have to wager a certain amount of funds within a certain time frame in order to be eligible, with this time frame almost always being either daily or weekly.

Many online casinos operate some form of loyalty bonuses to reward their customers for playing with them, with these proving to be a great way to earn extra bonuses as they provude players with bonus funds that they would have otherwise been ineligible for.

Free-to-Play Games

Free-to-play games are completely free to enter and can provide players with free spins or bonus funds to use on certain games..

The frequency of these is almost always daily, however some online casinos will have weekly free-to-play games as well.

These can be skill-based, such as Grosvenor's number match game, spin the wheel games or a slots-style machine, with all offering a range or free spins or free casino bonuses.

Then again the chance to win something from nothing is too good to pass up and an eye should always be kept out for any and all free-to-play games with casino sites.

Special Jackpot Games

Some online casino sites will run monthly, weekly or even sometimes daily special casino games that offer massive jackpots.

These will often provide a game with one of the highest potential payouts out there, with all players invited to have a chance to win.

Users will have to wager their own cash for these, but in turn will have a chance to win the special jackpot, with the amounts on offer usually being £1,000+.

The opportunity for these is often too good to pass up, and users will be aware of these special jackpot games weeks before they occur, able to plan for them.

Online Casino Bonuses FAQs

How do I claim a Casino Bonus?

Claiming any casino bonus is usually a very straightforward process. Players simply need to sign up for a casino site, enter a promo code if this is required, and from here adhere to any steps laid out by the casino site.

This could be depositing a certain amount or wagering a specific amount, with all the relevant nformation being easily locatable in the T&Cs of each casino site.

What are wagering requirements?

Wagering requirements are a set of terms & conditions that casino sites apply to winnings off of bonus funds.

Bonus funds earned off of a casino offer must then be wagered a certain amount of times before any winnings can be withdrawn.

For instance, if a casino offer has a 10x wagering requirement from an offer which gives them £10 in bonus funds, they would have to wager that £10 10 times before being able to withdraw any winnings earned off this.

Can I cash out my casino bonus?

No, bookmakers do not allow for casino bonus funds to be cashed out as users are essentially playing with house money, thus the house will then not allow them to cash out these bonuses for real cash at any time, with you needing to wager this amount before being able to do so.

What happens if I win a bonus bet?

If a player wins a bonus bet then these funds will be placed into their account as real cash, with the initial bonus stake removed.

This is because the stake is house money, not the player's real cash, to begin with, and as such will not be returned to the player, but any winnings or profits will.

All that is then left is to see what the wagering requirements are, or if these can be removed immediately, which can always be found in the T&Cs.
