The Best Online Casino Reviews & How We Rank Top UK Casino Sites

Any of the best UK casino sites that intend to stay on top of the rankings must comply with a number of features. Below are a few criteria, from Casino Deal’s point of view, to help you understand why we publish the best online casino reviews.

Variety of Games at UK Online Casino Websites

Casino and games: There must be a wide variety (slot machines, roulette, cards, etc) and gameplay options (live, mobile, progressive prizes, etc).
Progressive Jackpots: How much are the jackpots? Jackpots are the main attraction for players who like to compete for huge sums. After all, who doesn't want to become a millionaire whilst having fun?
Casino Bonuses: Welcome bonuses and promotions make a difference to both new customers and loyal members. The bonus funds, bonus terms and first deposit offers are the factors that accumulate many points in reviews.

Live Casino & Hosted Live Casino Games at Casino Deal

With some great Live Casino software providers out there, our reviews make sure they cover in detail this side of things. There are also dedicated live casino bonuses, live casino welcome bonuses, as well as live dealer wagering requirements too.

Casino Deal's Most Trustworthy, Safe & Secure Licensed UK Online Casinos

All online casinos must have permits for operating, provided by the government agencies for the country where their headquarters are, to act legally. Not just the best online casino sites, but all online betting sites must have an appropriate operating licence.

In order to accept new customers in the UK, every online casino must be licensed by the UK Gambling Commission. The most common licences held by the best online casino sites are from Malta and Gibraltar. The casino platform is developed to focus on protecting financial activities and preventing player data leakage and transactions. There are technologies, such as encryption, that prevents hackers from accessing the system. Therefore, our top recommended online casino sites are the most secure sites; security comes first.

Casino Deal's Most Popular UK Online Casino Payment Methods

Online casino deposits and withdrawals must be both fast and safe. A quality online casino website should accept various casino payment methods, from debit cards to digital wallets, for UK players to withdraw bonus money.

Popular Debit Cards Accepted at UK Online Casinos:

  • Visa and Maestro – Worldwide leader in payments, Visa is accepted at all online casinos, whilst Maestro is accepted at ‘most' top UK casinos. They are well-trusted online payment options with a very good international reputation. Please note that credit cards are no longer accepted at online casinos.

The Most Popular Prepaid Payment Option for UK Online Casinos is:

  • Paysafecard – The leader in online prepaid payment methods. Used by many online casinos for the acceptance of deposits only. It is the most common prepaid card in the online casino industry. Of course, because it is a prepaid method, it cannot be used for withdrawals.

Popular e-Wallets Accepted at UK Online Casinos:

  • PayPal – The largest e-wallet service in the world, PayPal is the most popular online casino payment method. However, PayPal Casinos have regulations to meet. This is why only the most reputable online PayPal casino operators have this as a payment method for depositing and withdrawing. Players can deposit without a PayPal account, however, it is advised to have a PayPal account whilst depositing at UK casinos, for added security.
  • Skrill – Another highly reputable, industry-leading e-wallet is Skrill. Skrill is well-known in the online UK casino industry as a fast, convenient and secure option in the depositing and withdrawing of funds.
  • Neteller – Alongside PayPal casinos, Neteller is the leader of e-wallet’s in the online UK casino industry. Neteller is a trustworthy, safe and reputable online banking method. It is a chosen service for transferring funds in and out of online casinos due to its ease of depositing, lightning fast withdrawals, and strong security.

Other Popular e-Wallets Used at Online Casinos

  • ecoPayz – A diverse and flexible e-wallet, widely popular amongst online gamers. Established in 1999, with its head office in the UK, the best online casino players have full trust in this reputable payment method.
  • Trustly – Fast, uncomplicated and 100% secure. Online UK casino players do not have to register, as is the case with all digital wallets. A majority of all casino players own a normal bank account and use online banking, that's all they need for Trustly.

Popular Cryptocurrency used as Online Casino Deposit Methods:

  • Bitcoin – One of the newest emerging trends amongst keen online casino players gambling at Cryptocurrency Casinos. Only a few online casinos in the UK offer Bitcoin, but more are sure to come.

Casino Deal's UK Online Casino Customer Support Experience

An online casino should offer agile customer support, with professionals being fluent in English and able to solve any problem. Another big help is when customer support service hours are expanded to encompass weekends, and late hours. In other words, a 24/7 live chat customer support team is ideal. Online casinos offering Live Chat, Email, Phone and FAQs are certainly the most efficient and this is something that serious casino players should look for.
