Player safety is a big deal when it comes to casino sites.

Sometimes a casino will remove certain requirements such as the 'separate to cash funds' stipulation that's often attached to wagering requirements. UK casino sites with high-quality VIP packages often throw in faster withdrawal options as well. So while standard players may have to endure slower processing times, very important players will often be able to withdraw their bonus funds in half the time. Although min deposit levels usually stay the same, a lot of VIP schemes allow players to deposit larger sums of money - an ideal perk for high-rolling customers. The best UK online casinos, or certainly those with big budgets, often include standout prizes for their high-rolling players.

Quality of Live Casino

Available with tournaments, or as part of points-based schemes, these types of bonus giveaways can include things like luxury holidays, high-value consumer goods, and generous free spins deals. With many top casinos, online players who've attained VIP status will expect to be treated as such - and rightly so. It's therefore a very good sign if a casino operator bestows personalised gifts to their customers. One of the best ways to do this is to offer bonus deals and special gifts on birthdays - it shows that a casino is on the ball and that a dedicated manager is actively monitoring the player accounts. Pretty much all internet casinos featuring a VIP scheme will claim to offer a dedicated account manager. Accordingly, all the operators on Inside Casino are completely safe to use and fully licensed by the UK Gambling Authority. Security is going to be one of your chief concerns if you’ve decided to register and provide personal and/or financial information. Thankfully, all bona fide casinos use Secure Socket Layer (SSL) technology to encrypt connections and lock down your personal data. It’s easy to tell if a website uses SSL.

Your browser will display a padlock to the left of the website’s address. Should you come across an actual casino site without SSL, don’t even think about submitting personal information. If it purports to offer gambling games, you should treat the site with the contempt it deserves and leave.

What to Bet on at the Best Casino Sites?

Established and new casino sites in the UK and all over the world will probably apply wagering requirements at some level. Players hate them of course but without such stipulations, even the most successful UK casinos wouldn't be able to offer a worthwhile welcome bonus or bonus spins deals for very long. As per the UK Gambling Commission, wagering stipulations must be displayed in every single casino promo. Further details can also be found by clicking the 'Full T&Cs Apply' link. As we discuss on our bonus page (link provided below), wagering describes the number of times players need to play through a bonus before being able to withdraw any winnings.

UKGC License

In a lot of cases, bonus funds are considered separate from cash funds and will only contribute to the actual wagering rules. Despite this maddening T&C, many of the best UK online casinos will do their utmost to keep their play-through requirements at reasonable levels. As a general rule of thumb, we'd recommend avoiding online casinos that include wagering restrictions of above x65. Max bonus amounts often apply to multi-deposit welcome bonus offers and are usually pre-fixed with the rather ubiquitous 'up to' phrase: Claim 100% up to £70 plus 100 spins or 1st Deposit - Claim up to £70 and 100 spins In both instances, the £70 sum represents the max bonus. This means that you'll be able to deposit as much as £70 and the online casino will match it. Player welfare and licensing are also key considerations for online casinos in the UK.

Happily, we have the Gambling Commission which sets exacting standards for all British casino sites offering online gambling games. It’s one of the most respected regulatory bodies in the industry because it prioritises player welfare over profit. Thankfully, you can verify whether or not any casino sites are licensed by the UKGC by scrolling down to the home page footer. Hopefully, you will see a link to the Gambling Commission site along with a license number.

Which UK Casino Suits You? 3-Question Quiz

Considering how competitive the industry has become, a lot of casino software companies are under immense pressure to deliver fresh and innovative casino games on an almost constant basis. While this often results in the introduction of some superb games there’s also a lot of chaff - sometimes companies will dole out derivative games that don’t bring anything new to the table but instead rehash tired, hackneyed themes. Take a look at the number of online casino games based on Greek mythology for a prime example of this lazy approach. Thankfully, the very best studios manage to maintain exceptionally high standards when it comes to the development of casino games. Many of them also push the boundaries in terms of innovation and ingenuity - just think of the refined game mechanics that have been released over the past five years or so. If not, the casino site is either disreputable, does not include online gambling games (like Inside Casino) or is based in a foreign country. Thanks to the UK Gambling Commission, all games are rigorously tested to ensure fairness. These tests are conducted by independent third-party companies such as eCogra. All licensed sites in the UK must undergo these regular evaluations.

How we rate and review online casino UK sites

Although the word 'dedicated' seems to mean different things to different operators, the leading UK casino sites should allocate a team member to oversee player accounts, offer 24/7 support and help to deliver bespoke bonus deals such as tailored deposit promotions, free spins incentives, and such like. With the best UK online casinos, VIP players will be provided with clear information about the kind of perks available for any given package. Unfortunately, more than a few casino operators aren't exactly forthcoming about their VIP 'incentives' - this isn't usually a good sign. It's also quite a common practice to use the word salad in order to conceal substandard schemes. To be the best, casino online players should be treated to at least some of the perks mentioned above.

Clear, transparent information should also be provided to players about precisely what incentives are or will become available. What about the people behind the actual online casino and slot games?

Reality Checks

Recent regulatory changes now require operators to conduct a series of checks before assigning VIP status - they must also be overseen by a senior executive. So in the long run, this can only spell good news for players. But what elements help make a compelling VIP package? Offering VIP players standard bonus deals isn't really going to cut it in the UK. The best UK online casino packages usually include bespoke VIP casino bonus offers such as free spins as well as deposit and cashback bonuses that can be used for slots and table games.
