Best Online Bookies

In the UK, there are tons of betting sites online to choose between where the majority of sites is appealing to both beginners and professionals. The betting itself we will leave up to you as this site aims to give recommendations on what betting sites you should play at rather than on what games you should bet on.

Our aim is also to teach you how to identify good betting sites on your own. When evaluating betting sites online, the first thing you should take a look at is the general quality of the site regarding banners, graphics, and design. After you have visited a few betting sites, you will be able to recognize quality at first glance.

When evaluating betting sites, you should also pay attention to what platform the site is using. More or less every betting site, with a few exceptions rent a platform (which can be seen as the site’s engine) from a supplier specialised in developing technology for bookies. If you are experienced, you have most likely noticed that several pages look almost the same where this is the reason why.

Depending on what platform the site uses, it affects how many sports events you will be able to bet on. It also influences how fast your odds will be settled and in many cases also the odds themselves. Two of the most common platforms for online bookies are Kambi and SBTech where both are considered to be premium suppliers, and if being general when comparing them, Kambi is a bit faster when updating odds and also has a better solution for live betting and mobile use. SBTech, on the other hand, has more events you can bet on including traditional betting and live betting. Since we recommend becoming a member of several betting sites, fast payment solutions are important, as you want the possibility to transfer money from one site to another quickly. Hence, we always recommend betting sites that offer e-wallets like PayPal, Skrill or Neteller. At last, polite and professional customer service is key to a good betting experience as it often is the support team that manages everything from bonus issues to payments.

Best Odds

Intuitively, high-value odds are necessary for creating the best return on your betting. The best way to win on your bets is to combine good odds with your particular knowledge of the game. When you have chosen a game to bet at, make sure you are a member of a few different betting sites already and choose the best odds. It might be a good idea to use our calculator to check whether you have some real value in your betting tip compared to the bookies.

As an indicator, you can take the best odds you find for your bet and also add the best odds for the other possible outcomes. If the margin is negative for the fictive bookie, you most likely have identified a betting possibility with real value.

If you have identified several odds that for sure will give you value if playing all three possible outcomes in a 1×2 game you might want to place the bet at different betting sites making sure you win. This phenomenon is called sure betting and is completely legitimate to do. However, it follows with some risks as odds may be updated very fast and it in some cases takes time for the bookie to settle your odds.

The odds of the online bookies, of course, estimate the matches differently – they are people, just like you and me; there is no guarantee in their analyses. They can display entirely different odds, which means that the percentage of your refund is getting closer to one hundred and that you as a player get better opportunities to find value. This can be exploited to your advantage when you play so keep in mind always comparing odds before you bet.

Outside of the betting world, chances are often expressed as a percentage. If you flip a coin, the chances that it will land on the tail is 50% vs 50% for the head. Any possible outcome will in all cases be 50%. If you throw a 6-page dice, there is one in six chances that any of the numbers will appear. This means that the chance is 16.66% (100% divided by 6 possibilities). When betting, your chances of winning (odds) is expressed and calculated as described above.

Odds are simply the chance or probability of a particular outcome of an event. Each result has a certain chance or risk of occurring. By that, odds are simply an expression of these chances. Bookies provide odds or prices that match those chances. High odds correlates to lower chance of winning, and low odds suggest there is a greater chance of winning. If you bet on a game with high odds, chances are not to win as much, but if you do, you get better dividends.

Most online bookies give you the opportunity to choose what kind of odds you want to bet on, giving you as a player an option.

In our bookie comparison here at casivo.co.uk, we will only compare odds from our UK partners we have picked carefully where only the betting bookies we consider reliable and worth playing at. To find out exactly which these are, you can find them easily in the list on our site above.

Bookie Margin

With so many bookies claiming to have the best odds and an equally large number of sites comparing betting odds, how can you be sure you are getting the best deal?

In this section, we will simply try to explain how the odds work, assisting you to make an educated decision when looking for the best odds out there. It is smart not to place a bet without knowing how much it would really cost you. Bookies are always looking to win, regardless if you win or not, their profit is depended on how they adjust the odds to attract bets in the right proportion to secure long term profit. This is accomplished by providing odds that is higher than the actual statistical probability. This so-called, deviation represents bookies margin, i.e. what a bookie is charging a player for making betting available.

Have you identified a good betting opportunity and wonders what the bookie margin might be? By calculating the house margin using our calculator, it can be used as an indicator to see how good your bet actually is in the eyes from the bookie.

New Betting Sites

To explore new betting sites are exciting and fun, not to mention the joy in claiming a new welcome offer that often consists of both deposit bonuses and free bets. Before becoming a member of a new betting site, we want to emphasize the importance of making sure that the site is legit.

It goes without saying that the sites we promote at Casivo are reviewed and looked through when it comes to proper bonus offers and general safety. If planning to join a site that we have not reviewed, a good idea is to make sure that the betting site is licensed by the UK Gambling Commission which is the authority in the UK that verify that the site follows procedures and best practices handed out. If the site lacks the proper license, it is a big no-go as there is a high risk that something shady is going on.

Further, we also recommend making sure the most common e-wallets and credit cards are accepted for both deposits and withdrawals. If everything seems okay, we encourage our visitors to become members at new betting sites where the biggest incentive except a new betting bonus is that you will have more sites to cherry pick the best odds from and that you will be able to participate in more campaigns handed out by the operators.

Checklist new betting sites

  • UKGC license in place
  • Generous welcome offer
  • Weekly campaigns
  • Good odds
  • Fast payouts

Betting Bonuses

Betting bonuses are extremely favorable by the punters because these promotions can boost their credit balances and give them a financial freedom to try different things. Nevertheless, it is not always about the sign-up bonuses. Nowadays gamblers are given numerous other cash-back specials and exclusive deals that aim to keep their attention at a particular bookie.

It is not only recommended to become a member of several betting sites just to get the best odds, it is also so you can claim as many welcome offers and betting bonuses as possible. When becoming a member of a new betting site it is common that you get a welcome offer where deposit bonuses are most common. Compared to when becoming a customer at a casino site, the deposit bonuses tend to be a bit lower but are compensated with a lower wager requirement, often around five times your bonus money. When claiming a betting bonus, another common requirement is that you must wager the bonus on odds above a certain level, often higher than about 1,25 or similar. Not having such a requirement it would be too easy converting your bonus into real cash. Similar to what is described in the odds section, you can claim two bonuses and wager them towards each other until someone converts into real money.

Checklist betting bonuses

  • Minimum 100% deposit bonus
  • Minimum £100 in bonus
  • Free bets
  • Low wagering requirement
  • Unlimited winnings

Deposit Bonus

You should get a signup bonus when becoming a member on a new bookie. Often a deposit bonus of 100%, but sometimes even higher. A regular deposit bonus is for instance 100% up to £10 which means that the bookie doubles your deposit up to £20. Example: Deposit £10 and get £10 extra. As we mentioned before, the betting company has a turnover requirement that you need to take into consideration. The good thing is that they are not as high as for casino bonuses.

Free Bets

The majority of the betting sites online hand out their welcome bonuses in a so-called free bet fashion. The reason they are called like that is that you don’t necessary play with your own money but rather with a credit the bookie gives you. The amount you are given will usually be not taken off your first wager. Instead, you will be rewarded with a free token with equal value as your free bets. To withdraw your money, there will be wagering requirements you need to meet first.
