Top Sign Up Casino Bonuses

1. 888Casino – 100% Bonus up to £100

888Casino has long been regarded as one of the best in the business. As well as an appealing no deposit bonus, a 100% matched deposit, up to £100, is available to new customers. While a deposit of at least £20 is required, 30x wagering requirements are realistic.

Winnings are capped at £500, while players have 90 days to play the bonus through. While payment restrictions were found, the terms and conditions surrounding the 888Casino welcome bonus are fair. With thousands of games being available, it is well worth checking out what the casino has to offer elsewhere.

2. 2KBet Casino: 100% Bonus up to £100 + 100 Free Spins

2KBet was only founded in 2020. However, the brand’s online casino has already attracted many players. This is thanks, in part, to the welcome bonus on offer to new customers. Worth as much as £100 and the same number of free spins, a deposit of just £10 is required in order to qualify.

The bonus and winnings are available for 30 days, with 50x wagering requirements being in place. The maximum conversion is 3x the bonus amount, which should suit most players.

3. Grosvenor Casino – Bet £20 Play With £50

The bonus from Grosvenor Casino works a little differently. Here, a deposit of £20 will give players a kitty of £50. A deposit of £20+ will be 100% matched, up to £20, with players having to choose from a £10 bonus for Classic Slot or Live Casino.

Then, spend another £20 on any Grosvenor Casino venue and the casino will match it. Bonus funds will be available for 30 days, with other terms and conditions being favourable. With Grosvenor Casino continuing to make a major impression on the industry, having been around since 1966, be sure to consider this bonus!

The Best UK Casino Bonus Sites by Type

It’s all well finding UK casino bonus sites out there, but not all bonus-offering sites are the same. That begs the question – what are the best UK casino bonus sites by type?

By ‘type’ we mean the different kinds of bonuses a site typically offers. For example some sites frequently offer hefty deposit bonuses, others a countless stream of free spins bonuses, and others specific bonuses for their live casino games.

There’s also the scale of bonuses too, and by that we mean the way the bonus amount is scaled against other factors such as wagering. One thing you’ll notice when looking around casino bonus sites is that large bonuses tend to have high wagering requirements, while smaller bonuses tend to come with low wagering. It’s the same as high risk = high reward, and low risk = low reward. How you feel about this risk/reward ratio is up to you!

There’s payment methods too. Some casino bonus sites allow multiple payment methods for bonuses (including eWallets), while some simply do not.

To help you choose which bonuses might suit you best, we’ve listed a few categories of casino bonus sites below, and we’ve given you the best casino, in our opinion, which fulfils each casino bonus site type.

Different Types of Online Casino Bonus 

Some are undoubtedly more common than others. However, there are a variety of bonuses available to players at online casinos today. It is important to understand the difference between each bonus. Below is a quick breakdown of the online casino bonus offers players in the UK can expect to find:

Matched Deposit Bonus

As you will see from the table at the top of the page, the most common promotion for new customers is a matched deposit bonus. Here, new players will see their opening deposit rewarded by a bonus. This will be 50%, 100% or 200% of your deposit. As such, it can provide players with a large opening kitty. Of course, terms and conditions are found, including wagering requirements, payment restrictions and expiry date.

No Deposit Bonus

Such bonuses are hugely appealing to players. This is because no financial investment is required. Simply completing the registration process will result in a bonus, albeit a small one. This is likely to be as high as just £20. However, with this effectively being free funds to play with, online casino no deposit bonus offers are well worth taking advantage of.

Free Spins Bonus

For fans of online slots, free spins bonuses are likely to appeal. Rather than bonus funds, bonus spins are offered by online casinos. For example, Betfred offers 100 free spins to new players depositing £10+. Spins are likely to be available on selected slots, with wagering requirements once again coming into play.

Best Free Bets Casino Sites

• NetBet – 100% Deposit Match up to £200 + 10 Free Spins
• Betfred – Deposit £10, Get 50 Free Spins
• Kwiff – Bet £10, Get 100 Free Spins
• Mr Play – 100% Deposit Match up to £50 + 20 Free Spins
• Plaza Royal – 100% Deposit Match up to £50 + 20 Free Spins
• Mr Q – Deposit £10, Get 20 Free Spins
• Casiplay – 50% Deposit Match up to £50 + 30 Free Spins
• 888 Casino – £88 No Deposit Bonus

• BritainBet – 200% Deposit Match up to £50
• Mr Green – Deposit £10, Get 50 Free Spins
• Unibet – Bet £10, Get £50
• Monster Casino – £5 No Deposit Bonus

Reload Bonus

For existing customers, reload bonuses are one of the most popular bonuses. Offered to players who deposit over a specific amount in the required timeframe, reload bonuses are available at an increasing number of casino sites.

New Casino Bonus

Many sites are content to offer new players the same bonus, year after year. While the 'if it ain't broke, don't fix it' mantra might sit right for some, it's not something that we approve of when it comes to new casino bonuses. We like casinos that hang tight with the zeitgeist and amend their bonus offers on a frequent basis.

We also like to see new casinos pop up and offer tasty treats for the peeps who sign up with them. Make sure you keep an eye on our site as we will find new casino bonuses and new sites offering bonuses and report all our findings back to you.

Casino Bonus Sites Comparison

We have already listed our top ranked online casino bonus offers available today. However, the table below goes into a little more detail, including the key terms and conditions to consider: 

Which Payment Methods Can I Use For Online Casino Bonuses? 

As you will have read in the table above, some online casinos bonuses come with payment restrictions. This will mean that your preferred method of payment could be excluded from the promotion. In most cases, it is e-wallets that are ineligible. This means that punters looking to add funds via Skrill, Neteller, PayPal or Paysafecard may have to look for an alternative. Of course, having made your opening deposit, you can then switch to your no.1 payment option. With credit cards being banned for gambling purposes in the UK, it is recommended to use a debit card for your first deposit. This will put you in a position to qualify for any online casino bonus that may be on offer. 

Online Casino Bonus Key Terms and Conditions 

Before signing up with a casino, it is important to look at its bonus terms. Terms and conditions will impact both how players qualify in the first place, as well as how they profit from the bonus. Below are some of the most common bonus T&Cs, which players must familiarise themselves with:

How To Profit From Online Casino Bonuses 

No matter how good the bonus is, there are no guarantees that a profit will be made from it. However, there are steps which players can take to increase their chances of success. The following are our top 5 tips for profiting from an online casino bonus:

1. Check the T&Cs - Before claiming any casino bonus, be sure to read the small print. There is nothing worse than being surprised by the high wagering requirements or payment restrictions after signing up and depositing. 
2. Wagering Requirements Contribution - Different games will contribute varying amounts towards the wagering requirements. For example, slots may contribute 100%, while live dealer titles may only contribute 10%. Such facts will have a major impact on how quickly you can unlock bonuses.
3. Low Variance Slots - Low, or even medium, variance slots are well worth playing with bonuses. While the size of the wins here may not be large, the number will appeal to newcomers. Such games make reaching the wagering requirements all the easier. 
4. Track Your Progress - It can be easy to get carried away when using a casino bonus. However, rather than placing bets at will, be sure to regularly check on your progress. Doing so will allow players to see how close they are to reaching the wagering requirements. 
5. Forfeit the Bonus? - It may sound crazy, but in some cases, it is actually better to forfeit the bonus. Most players will bet with real money first, rather than bonus funds. In the event of winning big with your own money, it could be worthwhile withdrawing immediately, thus forfeiting the bonus.

How To Sign Up For An Online Casino Bonus 

It is nice for players to have an understanding of how to claim an online casino bonus before getting started. Using the bonus from 2KBet Casino as an example, the following step by step guide will help players on their way:

Step 1: Register an Account

Having selected the bonus that best suits your needs, it is time to register an account with the casino in question. Whether it be via desktop, mobile or tablet, enter the website of the casino. Click or tap on the “JOIN NOW” button. Complete the registration form by entering the required personal details. At this point, also create a password for your account. Click or tap “Submit” in order to confirm. Verify your account via email to complete the sign-up process.

Step 2: Deposit Funds

Login using your username and password. Enter the cashier page, before selecting the “Deposit” option. Select an eligible payment method from the list provided. Enter the amount, ensuring that you hit the minimum deposit requirement. If a debit card is selected, enter the card details, including expiry date and CVV code. Confirm the transaction and wait a few seconds for funds to appear within your account.

Step 3: Claim Bonus

Within 48 hours of making a qualifying deposit, the amount will be doubled in the form of a bonus. For example, if you deposited £20, your opening balance will be £40. If you have not received your bonus within this timeframe, contact the casino’s customer service team.

Step 4: Place Bets

Place bets using your bonus in order to meet the wagering requirements. Look at which games are eligible, as well as how different titles contribute more to the wagering requirements. At 2KBet, this is 50x the bonus amount. 

Step 5: Withdraw Winnings

Once you have met the wagering requirements, withdrawals will be available, should you have money left. When ready, enter the cashier page again, this time selecting the “Withdraw” option. It is recommended to use the same payment method for deposits and withdrawals. However, if you wish to use an e-wallet to speed things up then that is allowed.

Bottom Line on Online Casino Bonus Offers

When the terms and conditions are realistic, there is little doubt that an online casino bonus can be hugely rewarding for players. The majority of bonuses are reserved for new customers. However, reload and cashback bonuses help to keep existing customers satisfied too. Be sure to check out our top ranked offers, each of which comes from a licensed and fair online casino.
