The Best Odds Guaranteed Bookmakers in the UK

If you’re looking for sports betting operators that can offer you the best odds and guarantee them, then you’re in luck. In this guide, we will go over what we consider to be the top-performing operators on the market that offer best odds guaranteed.

Top Best Odds Guarantee Betting Sites

The best odds guaranteed offer is hard to find, and only a few operators have it. Two of the most notable ones are William Hill and Coral. We’ll also show you your alternatives among offshore sportsbooks and whether any offer a best odds guaranteed promotion. Check out our ranking below:

Bear in mind that although these operators are offshore sites, they are still licensed by a major and reputable regulator. Examples include the MGA, GCB, and the Government of Curacao. Even though you may not get the best odds guaranteed at these sites, all of them offer bet boosters that work in a similar way.

Best Odds Guaranteed Explained and Availability at Offshore Operators

As we have already mentioned, few bookmakers offer best odds guaranteed as a feature or promotion. The way it works is that when you make a bet or a selection at a lower price, and it ends up drifting higher, the operator will also upgrade your payout to match the new level.

If the betting odds drop and your position has higher odds, the sportsbook will keep your position, in a way ensuring that it can guarantee the best odds. Of course, there are limitations to this. Most UK bookmakers that offer best odds guaranteed promotions have certain time windows.

For example, if you have the best odds guarantee for UK and Irish horse racing bets, you will be able to start wagering from 9 AM on the day before the start of the race. Bear in mind that no matter what odds you take, the BOG offer will ensure that you get the best possible outcome no matter how the payouts change.

Also known as BOG (Best Odds Guarantee), it is a rare sight at offshore operators. But they have something else up their sleeve. They frequently offer boosted odds both as part of a promotion and on an event rotation on the website. They will provide a much higher payout when you make a boosted bet.

Boosted Odds as an Alternative to The Best Odds Guaranteed Promotion

Most operators on our list won’t offer a BOG promotion, but nearly all will offer boosted odds. They are hand-picked events by the bookie where the payout is increased, allowing punters to take advantage even if they place a bet at min odds. 

How to Claim the Welcome Bonus at The BOG Bookmaker Alternatives

While none of our top operators offers the best odds guaranteed, they do have generous bonuses that you can claim on top of using the odds boost. We would like to give you a step-by-step guide for that. First, you will need to create a new account and go through the ID confirmation process.

  1. Create a new account and go through the confirmation process.
  2. Once the account is activated, go to the Deposit section of the platform.
  3. Make your initial deposit and opt in for the welcome package. Sometimes it may be necessary to place an early bet to activate the offer or enter a promo code.
  4. Ensure that you transfer at least the minimum eligible sum.
  5. Your funds will be available nearly instantly, and you can go ahead and use the odds boosters to play.

You can now go ahead and make your initial deposit. The top bookmakers offer a high deposit match as part of the welcome package, so ensure that you transfer at least the minimum required sum. In some cases, you will be required to place your first bet or enter a promo code to activate the offer.

Wagering Requirements of Online Bookie Bonuses

Any kind of betting promotion at online bookmakers comes with its own terms and conditions. The most notable part of them is the wagering requirements, which need to be completed for the bonus and winnings from it to be unlocked for withdrawal.

The specifics of the wagering requirements of our offshore operators will differ when compared to the top UK bookmakers offering best odds guaranteed. The offshore bonuses will usually be valid for 7 days after activation, and you will need to play through your bonus and deposit amount between 30x and 45x depending on the operator.

Best Odds Guaranteed Offer Alternative Bonus Types

Except for the quite generous welcome packages, our offshore betting sites that are alternatives to best odds guaranteed bookies have a wide range of other promotions. They can vary from standard deposit match (reload) offers to daily deals, cashbacks and free bets. Let’s go over the most notable types in the coming sections.

Deposit Match Bonuses

These are probably the most widespread type of bonus at gambling platforms in general. They will offer you a match to your deposit, usually between 50% and 100% and reward you with bonus funds. They come with wagering requirements, so ensure that you read them fully. Sometimes, you may be required to make a qualifying bet in order to activate the promotion.

Free Bets

Usually offered as part of a welcome package, free bets are a great way to explore and test online bookmakers in the UK. They can also be given out separately as part of a promotion or a giveaway. You can regularly see them also as a daily deal. Bear in mind that you won’t receive the best possible odds with them.

Cashbacks

Cashbacks are an excellent way to apply some damage control to your gameplay. Even if bettors receive the best possible odds guaranteed, their wagers may still be losing ones. This is where this offer comes in, allowing you to return usually between 10% and 25% of your losing bets as straight cash to your account. Bear in mind that free bets don’t usually come with wagering requirements.

Daily & Weekly Deals

They can be any type of bonus, such as a deposit match, free bets, cashback or anything else. Most betting sites in the UK will have a few daily or weekly deals on rotation regularly for recurring players. We would like to advise you that they still can come with wagering requirements, so read the fine print.

Pros & Cons of The Bookmakers Offer Best Odds Guaranteed Vs Offshore Bookies with Odds Boosts

Here, we would like to make a comparison between the bookmaker sites that offer BOG and our alternative offshore sites. Of course, the most important differentiation is that one has a best odds guarantee, and the other doesn’t. Check out the table below for more details:

Available Sports at BOG Bookies and Offshore Betting Sites

Operators that have a best odds guarantee, such as bet365 and William Hill, will have a wide range of sports and markets available. On the other hand, our best betting sites that offer boosted odds instead have an even better selection due to the lack of strict control from the UKGC. Here is a short list of the most notable sports and their leagues:

  • Soccer – UEFA (Champions League, Europa League), La Liga
  • Basketball – NBA, WNBA
  • Tennis – ITF Men, ATP Challenge Tour
  • Ice Hockey – NHL, SM-Liiga

How to Pick Alternatives to The Best Odds Guaranteed Sites

Picking an alternative betting site that doesn’t pay the best odds guaranteed can be daunting, but with our list of key criteria that our team of experts uses, it will be smooth sailing. As new UK customers to these platforms, you will first need to confirm that they are licensed by a major regulator, such as the MGA or GCB.

  1. Check the operator for a valid licence by a reputable regulator.
  2. Ensure that there is SSL encryption to keep your data secure.
  3. Next, you should see if best odds guaranteed applies to this operator or if boosted odds are featured.
  4. Take a look at the available sports, markets and bet types.
  5. Check out the available bonuses and see which one fits you the best.
  6. Ensure that there is a 24/7 customer support team available.

Next, you should confirm that the website features SSL encryption, as it offers a very high level of protection for your personal data. Next, you can double-check if you will get best odds guaranteed, but you usually won’t. That’s because these sites offer boosted odds instead.

Once the previous steps are done, you should take a look at what sports, markets and types of bets are featured on the platform. It is also a good idea to see how good the bonuses are at that operator, as they can give you the best value for your money. Next, you should take a look at the available payment methods and finally confirm that there is customer support available 24/7.

What Else Can You Do at Offshore Sports Betting Sites

Except for sports betting, our top operators on this page have another side to their platform. They offer a complete gambling experience as they also feature online casinos. If you’re into that type of gameplay or just want a break from making bet after bet, then this is for you.

  • Slot Games
  • Table Games
  • Card Games
  • Live Casino Games (With Real Dealers)
  • Crash Games

You can take advantage and play a wide range of titles from various categories, such as online slots, table games, card games, live casino games, and even crash games. You will be astonished at the sheer variety of their game selections, with thousands of entries. 

Slots are the most popular due to their easy-to-understand mechanics, beautiful themes and laid-back gameplay. Table games will allow you to enjoy some of the classics, such as roulette, blackjack and video poker. Live casino games are played in a lobby with a real dealer and other players, offering an experience as close to a land-based establishment as possible.

Available Payment Methods at Online Bookies with Best Odds Boosts

It is crucial for any player to have a convenient and reputable payment provider that can handle their transactions. Our top sites outshine BOG bookies with a more varied selection of payment options and the support of cryptocurrency payments. Check out for more details below:

Bear in mind that withdrawals can take longer to be carried out. This is due to confirmation processes on both the side of the betting site and the payment provider. If you’re looking for a method that not only handles your withdrawals rapidly, but also doesn’t apply high fees, then pick from one of the e-wallets or use cryptocurrency.

Responsible Gambling Information

Even before placing a single bet, you should be aware that gambling can lead to the development of detrimental habits and addiction. That is why we always advise our readers to play responsibly and never to wager something they can’t afford to lose. You can use the responsible gambling features on most betting sites to help yourself, such as self-exclusion, session limits and deposit limits.

Final Thoughts: Which Bookies offer Best Odds Guaranteed and Alternative Sites

The best odds guarantee (BOG) offer will ensure that you are always getting the best value and get the highest odds. Of course, only UKGC-licensed operators can offer that, and it is relatively rarely seen outside of them. That is why we have hand-picked the best alternative betting sites that instead of BOG, will offer you boosted odds.
