Online Casino Bonus – UK Casino Sites Welcome and Reload Offers
Ready to play for real money at the online casinos? Make sure you take the opportunity to claim the value on offer from the casino bonus.
This is the advantage of playing casino games online rather than in the retail casino, arcade or high street bookmaker.
Online casinos offer casino bonuses to UK customers. These can be welcome offers when you sign up, add your debit card to your account or make your first deposit.
Reload casino bonus offers are given when you make more deposits or just play at the casino site online.
Most UK online gambling casinos provide a variety of different welcome bonuses as an incentive to sign up for their services. This type of deposit bonus is received once a player creates an account with the online casino site then makes a deposit. The most common offer is usually the player having their first deposit amount matched by the UK casino site with a deposit bonus.
Deposit Bonus Terms & Conditions
The welcome offer deposit bonus varies per site and per offer. Offers range from no deposit bonus for the casino, free spins, or a 100% matched deposit bonus (or even 200% match deposit bonus). The deposit bonus amount for a deposit match can be as high as £1000.
Even at the best casino sites, casino bonuses have terms & conditions and restrictions. Matched welcome deposit bonus normally requires the player to perform a certain number of bets, known as a wagering requirement.
A typical wagering requirement is thirty-five times the amount of the deposit bonus. Bets may be restricted to specific online casino games and the bonus may have a cap on the maximum win and withdrawal amount.
A max bonus conversion is a limit on the amount you can win from the bonus and have transferred to your cash funds. If there is a limit, typically the max bonus conversion equal amount is a multiple of the deposit bonus.
At a UK casino site like Skol Casino, wagers with only bonus funds contribute to the wagering contribution.
Other T&Cs apply, such as free spins bonus can only be played on eligible casino games, such as exclusive games, game weighting applies, game contributions vary there may be a max bonus bet allowed of £5, for example.
Other restrictions in the terms and conditions of the offer are the expiration. Offers usually must be completed within 30 days of first being claimed.
The best way to understand the welcome bonus at an online casino is to read the terms and conditions. Find the casino bonus offer that best suits your play style.
The best casino sites offer a good variety of promotions and bonuses, the most important being a welcome bonus. Registering for a new casino is a great opportunity to take advantage of these welcome casino bonuses.

Some sites require you to play through an amount of money before being able to withdraw. This can be anything from 1 to 50 times the amount of the casino bonus. Bonuses can also be limited by time or date and even attached to a certain casino game. Be sure to read the terms and conditions of different online casinos before claiming.

What Are Online Casino Bonuses?
What is a Reload Bonus?
Free Spins Deposit Bonus at UK Casino Sites
The free spins deposit bonus is a type of casino promotion that offers players free spins on slot machines. The free spins may be in addition to deposit matched bonus money.
Free spins, sometimes referred to as bonus spins, are usually credited to a player’s account after making a qualifying deposit and can be used on selected slots.
Bonus wins from free spins are often subject to wagering requirements and max bonus conversions.
To avoid wagering requirements, look for no wagering casinos like MrQ Casino.
Casino sites typically offer free spins bonuses as part of a welcome package or as a reload bonus.
The benefit of free spins deposit bonuses is that they a great way for players to try out new slots and casino games. They also provide an opportunity to win real money without risking as much of your own money.
Online Casino Site Withdrawals
If you have been lucky and enjoyed a big win then it is time to withdraw back to your payment method!
British casinos differ online in how quickly each of the sites transfers requested funds back to the customer. The difference between sites can be multiple days.
This is often overlooked before joining your next internet casino site, so don’t get caught out. Check out our reviews and know in advance how quickly each site pays out.
All online casinos have set restrictions on withdrawals that players are able to make. The restrictions can come in the form of an ‘Amount Limit’, ‘Time Limit’ or possibly a combination of the two!
Amount Limit
An Amount Limit is any amount of money that the casino allows to be withdrawn in a single transaction.
For example, a casino can limit you to making a withdrawal of £5,000 in one go.
Established casino sites have the same minimum withdrawal amounts that they have for deposits, plus high maximum daily payout limits.
This is an area where casinos are very different. Many unfortunately use higher minimums, introduce payment caps and pending periods for withdrawals.
Knowing the payout policy of the casino is a very important aspect in deciding which site suits your needs best. For example, Coral Online Casino has a minimum deposit of £5 and no maximum withdrawal amount. It is also important to remember however that bank or card issuers may have limits in place.
Time Limit
A Time Limit is when an online casino limits the number of withdrawals a player can make within a specified time.
You might only be allowed to make one withdrawal per day or twenty in a month for example.
Time and Amount Limit
Most online casinos set up a limit that combines both time and amount. For example, you may only be allowed to make a cash withdrawal of £5,000 per week.
For most players, these limits are not usually an issue. Casual online gamers make relatively small deposit amounts, small bet sizes and withdraw relatively small amounts.
However, when it comes to high roller players these limits can create issues and can often become quite complicated.
High roller players make larger deposits, bet bigger amounts and also want to make bigger withdrawals from their accounts. When this happens online casino providers make special exceptions for these players. These withdrawals can be negotiated on a case by case basis with the online casino customer support teams.
Withdrawing funds from your online account is the best part of online casinos. Lucky and skilful players can often withdraw more than they are depositing. In recent years, like depositing, withdrawing has become seamless.
During the sign-up process, the online casino will let players know what payment methods are accepted. Whichever method is used to deposit must also be used for withdrawals. It should be noted that not all payment methods offer a withdrawal option. The player will therefore have to provide an alternate method for withdrawals.
Does it cost to withdraw?
Popular online casino sites in the UK only charge to withdraw if players are using an alternative method such as PayPal.
It is normal for withdrawals to a debit or credit card to have no cost associated with them.
This information should be pointed out to players during the sign-up process. Consult that casino’s online help centre, FAQs or live chat service before joining.
How long will it take for the money to show up in my account?
Unfortunately, there are no set standards across online casinos in the UK when it comes to withdrawing your winnings. Withdrawal times depend on payment methods and time of year for example.
For players using payment methods like debit cards, it will usually be back in your account within two days. Sometimes this can take up to five days.
Is there a maximum or minimum withdrawal limit?
This is something that does exist at the majority of online UK casinos but varies greatly. Players may find that they are limited to a daily, weekly or monthly withdrawal amount. Players should again consult the specific casino’s guidance for detailed information.
Payment Methods at UK Casino Sites
The majority of casino sites we feature will accept a good variety of methods including Visa and Mastercard. Some will accept PayPal, some will let you pay by phone, and some will accept alternative payment methods.
It is also important to understand and look out for fees associated with withdrawing – read the withdrawing section above.
What to check
There are a number of things players should check before they can comfortably start playing at the best online UK casinos.
If players live outside the UK they are still able to use certain online casinos featured at Casino Sites Online. Sites are available in various currency and language options. Some casinos are restricted from operating in certain countries and can not accept players from there.
The accepted payment methods change from casino to casino. Players will see the accepted methods in our reviews. It is important to make sure that whichever online casino you choose accepts your preferred payment method for withdrawals and deposits.
Online Casinos accept a variety of payment methods. We have listed some of the most common payment methods that online UK casinos use below.
VISA
All licensed UK online casinos accept deposits made by Visa debit card and usually without a transaction fee. The only consideration for Visa users at online casinos is to update your saved card details. Do this when you receive a replacement card from your bank (if you have suffered a theft, loss or card expiry).
Mastercard and other Credit Cards
The UK Gambling Commission announced a ban on casino sites allowing customers in Great Britain to use credit cards to gamble. From April 2020 credit card payments are no longer accepted by UK casinos. This was introduced as a measure to protect vulnerable people from experiencing gambling-related harm.
Maestro Casino Review
Maestro is actually owned by Mastercard. It is a debit card network and you can therefore use this to fund your casino account quickly and easily. This can either take the form of a debit card or a prepaid card.
Online Casino E-Wallets
Less known to casino customers is the e-wallet deposit method. There is an increasing range of e-wallet solutions available at online casinos. Examples are Skrill and Neteller.
PayPal
PayPal is a great way of making casino deposits and withdrawals. Payments in and out are often instant so money is transferred to your account quicker than the debit card method. The only requirement is that you must make sure your PayPal is actually linked to any major bank debit card.

Paysafecards
Many customers use Paysafecards because it is a secure casino deposit method. It allows online casino site players to deposit funds to a prepaid card, like a gift card. Bank accounts and credit cards are not needed, just find a local sales outlet and buy the Paysafecard there. You can then use that Paysafecard to pay online into your casino account.
Customer Service at Online Casinos
Online casinos have dedicated Customer Service teams for resolving customer queries and complaints.
They offer a variety of means to communicate with them. Contact methods provided by casino sites online include live chat, an email address and a dedicated telephone number.
Customer Service can also be contacted by Facebook messenger, WhatsApp, and Social Media at the best online casinos UK.
Times of customer support availability vary across sites. For example, Casino.com provide a 24/7 service. BGO casino is only contactable between 10:00 am and 10:00 pm.
What We Consider When Reviewing Customer Service
As these UK online casinos are dealing with real money it is important to know that they offer good customer service. The majority of these sites say that they have good customer service as they know it is valued by players. Because of this, we are very critical and precise when researching and reviewing this important component of online UK casinos.
It can be particularly stressful for players when they feel they have lost their money unfairly. This is why it is imperative for the best casinos to offer a range of customer support avenues that operate efficiently.
Live chat is usually able to provide the quickest and most reliable customer service to players experiencing problems. It also provides players with confidence during problem-free playing sessions. However, new casinos also need to provide excellent customer service when actually dealing with customers.
All UK online casinos reviewed at Casino Sites Online include our experience of contact with the customer service teams.
Joining Process at UK Casino Sites
Congratulations, you have sifted through our reviews and selected the UK online casino that is perfect for you! Now the next step is to sign-up and take advantage of that generous welcome casino bonus. Before starting the sign-up process be sure to have your selected payment method ready.
- Go to your chosen casino and select ‘Join’ or ‘Register’.
- Most casinos will now ask players for personal information such as an address, email, date of birth, phone number and name. They may even ask for identification such as a passport or driving license scan.
- The next section of the registration process will require you to enter the information for your chosen payment method. Be sure to have checked that your currency is accepted.
- Once this is completed you may have to verify your email.
Joining most online casinos is a simple process. Use the Join Now or Register button on the homepage to begin the registration process. The next step requires you to provide information about yourself including your name, email address and mobile phone number.
How to prepare
Some online casino players prefer to keep casino offers separate from personal or work emails. One way to manage that is by creating a new email address and using it just for online casino gambling accounts.
What to expect
When joining you will need to provide personal details such as your name, date of birth and address. This is for the casino site to be able to complete an electronic identity check. The check will verify that you are a UK resident and over eighteen years of age.
Some sites may ask you for identity documentation. This is to prove that the information you have provided is correct. Acceptable documentation would be a photo of your passport or driving license.
You may also be asked to enter your mobile number and have it confirmed to be able to join the site. For most sites, you will simply be asked to provide verification via your email address.
The final step of the registration process at online casinos is to select a username and password. The site will prompt you to select a secure password to protect your account. Use at least 8 digits, avoid easy to search or guess phrases such as your name. A random 8 digit combination is often the best approach to guarantee a secure password.
Finally, choose a name you are comfortable with as it will most likely be unchangeable and on some sites may be publicly visible.
Depositing Money at English Casino Sites
Now that you have completed the registration process the next thing to do is fund your account. Depositing money into your online account is easy and you can start playing with the real money casino games.
Go to the deposit page that should have been suggested once you finished registering. It should also be located in your ‘My Account’.
Select your payment method and how much you want to deposit.
At this point, you should be aware of any fees associated with depositing or withdrawing using that payment method. Check the terms and conditions of the welcome bonuses as you may have to deposit over a certain amount to qualify.
After clicking submit the casino will accept your payment method. You should see your balance at the top of the screen in your casino account.
Regulation, Security and Safer Gambling
Who regulates online gambling in the UK?
The UK Gambling Commission licenses and regulates the people and businesses that provide gambling in Great Britain.
The UKGC was set up under the Gambling Act 2005. It regulates commercial gambling in Great Britain in partnership with licensing authorities.
The requirements of licensed online gambling sites are the Licence Conditions and Codes of Practice. Licensed websites are assessed to ensure they are following the requirements and can therefore be considered to be the best casino sites.
This ensures that all online gambling businesses comply with the industry regulations and standards as highlighted in their licensing agreements. The UKGC protects players from unfair gambling services and ensures a safe and secure environment both online and at physical casinos.
All regulated online casinos in the UK have secure protection methods for player wallets and funds in their websites and apps. Casino games are checked by organisations like eCOGRA. They ensure that online casino games are fair for all players and payout at the advertised rate.
Why you should only play at regulated online casinos
Regulation, Security and Safer Gambling is a very important concern for players when choosing an online casino. Everyone wants to feel safe and know that their money is protected. The best new online casinos in the UK are regulated and use the latest online security features. This makes sure that there is a safe and enjoyable environment for all.
Regulated UK casinos are amongst the most secure in the world. The Gambling Commission regulates all commercial gambling in Great Britain in partnership with licensing authorities.
This means that the UKGC regulates all of the best new online casinos in the UK. They do this in addition to UK physical casinos, all sports betting, arcades, bingo, the National Lottery and more.
Moreover, all online casino sites operating in the UK must obtain a gambling license from the UK Gambling Commission. This is the only way they can legally provide classic casino games such as slots and card games to UK players.
It is important to note that there are online casino sites out there operating illegally outside the regulation of the UKGC. These should be avoided. Online casinos in the UK must display their license number at the bottom of the home page. Players will only find safe, regulated online casinos that hold a UK license on Casino Sites Online.
