Here’s an overview of the best BOG sites in the United Kingdom:

1. Betfred best odds guaranteed

Betfred is one of the UK’s leading bookmakers. It strongly focuses on horse racing, featuring competitive odds-on numerous UK and Irish racing markets. The common wagers are singles and each-way. However, Betfred also makes accommodation for accumulators.

Betfred’s BOG is available on all UK and Irish horse racing from 8 AM on race day. Only win and each-way singles qualify. The promo does not apply to multiples or ante-post bets. No maximum benefit cap is stated. Free bets and bonus bets are excluded from BOG.

To qualify, place bets on eligible races before the start. This can be carried out on the website or the Betfred mobile app. There is no need to opt in or use a promo code, which makes it simple for all punters. 

2. bet365 best odds guaranteed

bet365 is a global bookmaker with a strong reputation for horse racing. It covers UK, Irish and international races. There’s a wide range of markets and competitive odds. Singles, accumulators and each-way bet types are all supported. The sports are easy to navigate on the web and mobile devices.

Their best odds guaranteed is only applicable to races held on British grounds. Bets can only be placed starting from 8 AM on race day. Only win and each-way singles are eligible. Betting on the odds require cash, as bet365 free bet credits aren’t allowed. Additionally, there’s no limit to the maximum payout.

To use BOG, simply place bets on eligible races before they start. Not all markets are included, so review qualifying bets.

3. BetMGM best odds guaranteed

BetMGM has earned a reputation in the US market. The UK model is also reputable, especially in terms of horse racing. It includes races from the British circuits, providing multiple betting options. The common ones include singles, accumulators and each-way bets.

BetMGM’s best odds guaranteed promotion becomes active by 11 AM on race day. This is slightly later than many competitions. The promo is only available to selected bettors, whom the bookmaker chooses. There’s also a £10,000 daily win cap.

The late start time and selective eligibility make it less attractive to players. Also, BetMGM reserves the right to tweak or withdraw the offer anytime. Before placing the wager, ensure to verify the offer is still available.

4. Betway best odds guaranteed

Betway is a major UK bookmaker with strong horse racing coverage. It offers various markets and betting options, including singles, accumulators and each-way bets. The platform is accessible via desktop and mobile.

The BOG applies from 9 AM on the race day, slightly later than some competitors who start at 8 AM. However, it is earlier than BetMGM’s 11 AM. Specific markets, such as ante-post, international meetings and bonus markets, are excluded.

To qualify, place bets on selected races before they start. You can start with a minimum stake of £1, or £0.50 each-way. The maximum enhanced payout per day is £25,000. There’s no cap on benefit per bet; it’s just this overall daily ceiling.

5. talkSPORT BET best odds guaranteed

talkSPORT is one of the UK’s leading sports radio stations. It’s known by equestrian fans for live commentary on major events like the Cheltenham and Grand National.

talkSPORT BET, launched in 2022, brings talkSPORT’s sports heritage into online betting. It offers BOG on UK and Irish races. There’s also live streaming on its app, which lets you follow your wagers as they unfold. 

The BOG option is available at 9 AM on race day. It applies to horse and greyhound racing. In-play bets, cashed-out or partially cashed-out bets are excluded.

There’s no required minimum deposit for BOG. However, talkSPORT BET has a £10,000 cap on the extra cash benefit, which are the additional winnings gained from the BOG upgrade.

6. Tote best odds guaranteed

The Tote has been a cornerstone of UK horse racing since 1928. It remains the largest online pool-betting operator. Tote has a huge presence at nearly every UK racecourse and a robust digital platform.

Since Tote is based on pool betting, the traditional BOG doesn’t apply. The structure used is referred to as a Tote Guarantee. Here’s how it works: If the Tote pool dividend exceeds the industry starting price (SP), you get paid more. Tote’s “Tote Plus” adds a 10% bonus on top of dividends.

No separate qualifying deposit or special bet is needed. However, the maximum stake is £500 per selection. Simply place a Tote Win or Each-Way bet (Win part) via web or app to become eligible.

7. Midnite best odds guaranteed

Midnite is a newer UK-focused betting operator. It’s best known for its strong esports markets and modern mobile experience. Midnite also showcases horse racing and betting. The bookmaker live streams and replays thousands of annual UK track events; however, it doesn’t offer the best odds guaranteed option on these events. 

The bookmaker is relatively new, and there’s a high chance BOG will be integrated soon. This is why we added it to our review. 

Concerning its other horse racing features, Midnite features 33,000+ races annually from more than 50 UK tracks plus Irish fixtures. Bettors enjoy live streaming daily from 8 AM–10 PM and free replays of all ATR races with a low £1 minimum stake.

8. Coral best odds guaranteed

Coral is a long-established UK bookmaker, blending extensive high-street presence with a feature-rich online platform. The bookmaker is highly regarded for live horse racing streaming, free-to-play tools and promotions. Coral also delivers a robust betting experience via its web platform and mobile betting apps.

Coral’s BOG is available on all UK and Irish horse racing. It’s also available on greyhound racing. The option is opened to punters by 8 AM on race day, ensuring early coverage for most UK fixtures. Stakes must be placed online or in-store with a Coral Connect card.

Bettors must use the main Win or Each-Way (Win part). For in-shop bets, maximum stakes per race selection apply with £50 on single Win/Each-Way, £25 on doubles and £10 on trebles.

9. 888 Sport best odds guaranteed

888 Sport is part of the longstanding 888 Group, a well-known player in the UK betting market, particularly for its casino expertise. The sports section at 888 Sport is also stacked with extensive features. For horse racing, you’ll find early prices, expert insights and blog content for punters.

The 888 Sport best odds guaranteed promotion requires that bets be placed on the race day. It can be activated between midnight and the race start. There’s no specific start time restriction. Only real-money bets qualify; however, bets made using Skrill and Neteller deposits are excluded.

BOG at 888 Sport is strictly for horse racing. Ante-post markets, international racing, enhanced or special offers aren’t permitted. The maximum benefit is £25,000/customer per day. 

10. Copybet best odds guaranteed

Copybet stands out with its unique tipster-following model. Punters can mirror expert selections automatically, offering novice and seasoned bettors strategic convenience. Its horse racing section features sharp odds, jockey and trainer form and races from most UK and Irish meetings. 

Coverage and qualifications for Copybet’s BOG apply to UK and Irish horse racing in the winner (win) market. Excluded markets include ante-post and future horse racing. BOG applies to bets placed after 8 AM on race day. There is no maximum win cap specified, so potential payouts are uncapped as per normal settlement rules. 

Review the qualifying races for limits, as they are subject to change.

Best odds guaranteed (BOG) explained

BOG is a popular promotion offered by bookmakers in the UK. BOG gives punters the best possible value on a horse racing bet. If the odds on a horse go up after placing your bet, it ensures your payout will be at the higher odds.

The odds on a horse race are based on numerous factors, such as form and weather conditions. These are subject to change, which impacts the odds. For example, if one of the favourites gets injured, it increases the chances of another horse winning. This causes the odds to change for the remaining horses. 

Despite the changes, a typical market will payout based on the odds before the injury. The BOG, however, flips that script. If the odds on your horse increase before the race, you’ll receive a payout based on those improved odds. The initially agreed-upon wager becomes nullified. This market applies to single, accumulator and sometimes each-way bets.

Here’s a practical example to show how it works:

The Royal Ascot is set to begin, and you find a decent horse at 4/1 odds to place a £20 bet. If the horse wins the race, you’ll win £80. However, before the horses are at the start gate, the odds increase to 5/1. The bookmaker will pay out at 5/1 rather than the initial 4/1. This change means you’ll win £100, which is £20 more than the wagered odds.

What if the odds decline to 3/1? You’ll get paid at 4/1, as BOG only applies to odds increase. It’s called best odds guaranteed for a reason.

BOG is typically offered on most races, especially in the UK and Ireland. However, its availability depends on the bookmaker.

The bookmakers that offer BOG mainly enable it on morning/early hours bets before the race. Other bookmakers prefer the lead-up to the race, as the odds are more volatile. This lets punters lock in an early price, knowing they could benefit from increased odds later.

Some bookmakers exclude certain types of bets from BOG, such as ante-post bets. The promotion might also not apply to every market, such as races with fewer horses.

The promotion is usually tied to certain terms such as time limits and minimum bet amounts. Reviewing the terms and conditions will help you familiarise yourself with these conditions.

How to qualify for best odds guaranteed 

Betfred ranks first on the list of best bookmakers that offer BOG. That’s why it’s the case study in this section. Understanding how to qualify is essential to take full advantage of this offer. However, note that the qualification process might differ slightly elsewhere.

Place a bet after 8 AM on race day

BOG applies only to bets placed after 8 AM on race day. Any bet made before this time does not qualify for the offer.

Bet on UK or Irish horse racing

The promotion is only available on select races in the UK and Ireland. Verify the qualifying races on the bookmaker’s site before placing your bet.

Avoid ante-post and special bets

BOG does not apply to ante-post bets. Lucky 15s, Lucky 31s, Lucky 63s and special market bets also don’t make the cut. Check the terms to ensure your bet qualifies under BOG.

Place single bets only

Best odds guaranteed is only available for single bets. If you place multiple bets or accumulator bets, you will not qualify for this offer. Stick to single wagers!

Use real funds for betting

Promo funds or free bets provided by Betfred can’t be used for the BOG option. Only place your bet with real funds in your account to trigger the offer.

Check for Super Extra Place races

BOG doesn’t apply to bets on Super Extra Place races. These are typically highlighted in the race book. Avoid betting on these if you wish to use BOG.

Be aware of Rule 4 deductions

Rule 4 deductions may apply if a horse is withdrawn from the race. In such cases, Betfred will payout at the higher odds after the deduction is applied to your bet.

By following these guidelines, you can ensure that your bet qualifies for the best odds guaranteed promotion.

Standard odds vs best odds guaranteed

To make the most of best odds guaranteed, you need to know how it differs from standard odds. Here’s how these two options compare in practice:

Standard odds

With these odds, you get the fixed price at the time of your bet. You keep the original odds if the odds shorten or lengthen before the race. 

Example scenarios:

• Odds shorten (standard odds):
  • Bet: £10 at 5/1
  • Starting price: 3/1
  • Payout: £50 (5/1)

No change: you receive the original odds

• Odds lengthen (standard odds):
  • Bet: £10 at 5/1
  • Starting price: 7/1
  • Payout: £50 (5/1)

No change: you receive the original odds.

Best odds guaranteed 

BOG ensures that if the starting price (SP) of your selection is higher than the price you took that you’ll be paid out at the higher odds.

• Odds lengthen (BOG):
  • Bet: £10 at 5/1
  • Starting price: 7/1
  • Payout: £70 (7/1)

You receive the higher SP.

Feature	Standard odds	Best odds guaranteed (BOG)
Odds adjustment	Fixed at the time of bet placement.	Adjusted to the higher of the odds taken or the starting price at race time.
Odds drop protection	If odds shorten, you still receive the original odds.	If odds lengthen, you receive the higher SP.
Potential for higher payout	Limited to the original odds; no opportunity for increased payout.	You will receive an increased payout if the SP is higher.
Availability	Available for all bets, including multiples and ante-post.	Typically applies to single bets placed after a specific time on race day. Exclusions may apply.
Restrictions	Applies to all bet types.	Excludes certain bet types, such as ante-post bets.
Timing	Can place bets at any time.	Must place bets after a specified time on race day, such as after 8 AM.
Free bet eligibility	Free bets are accepted. No impact on odds.	Free bets are generally excluded as BOG applies only to real-money bets.

BOG vs odds boost vs bet boost

BOG, odds boosts, and bet boosts are top promotions at sportsbooks. They are designed to add value to the punter’s gaming. Although the goal is the same, each operates differently. Here’s how they compare:

BOG

Best odds guaranteed is primarily used in horse racing sites. It only applies if the odds increase after a placed bet. Using the promotion is advisable when the odds fluctuate between placing your bet and race time. If the odds lengthen, you could walk away with a substantially higher payout. 

Odds boost

Odds boost is a promotion where enhanced odds are offered on selected markets. For instance, the normal odds for Liverpool to win their UCL game are 2/1. With an odds boost, the odds could become 3/1 or more. The odds aren’t subject to change, so you must take advantage of it before the event begins.

Bet boost

Bet boost works similarly to odds boost. However, it’s generally offered on multi-bet combinations or accumulators. A bookmaker might offer to boost the odds of your accumulator by a certain percentage, such as 25%. This can significantly increase your potential winnings if your multi-bet wager is successful.

Key differences:

Feature	BOG	Odds Boost	Bet Boost
Available on	Horse racing	Single bets, often on sports events	Multi-bet combinations (accumulators)
When it applies	After bet placement, if the odds improve	Before the event begins	Before the event begins
Value increase	Improved odds at race time	Fixed increase in odds	Percentage boost on multiple

Best odds guaranteed on free bets

BOG does not apply to free or bonus bets gained from welcome offers at any of our listed bookmakers. Only cash bets qualify for BOG. If you use a free bet, you will be paid at the odds taken, even if the SP is higher.

This industry standard applies to Betfred, bet365, Betway, talkSPORT BET, Coral, 888 Sport and Copybet.

Advantages of best odds guaranteed offers

The BOG option is used by several sportsbooks in the UK and Ireland. The option guarantees the best odds in the horse racing market. 

Do you want to try the promo, but are unsure of its benefits? Here’s a breakdown of seven advantages of BOG: 

1. Increased payouts

When the odds increase after a bet is accepted, BOG ensures that the payout is based on the higher odds. This can lead to a significantly higher payout if the horse you bet on wins the race. 

2. Reduces risk

With BOG, punters have peace of mind as they can’t miss out on the best odds. No matter which way the odds swing, only the highest odds will apply to their bet. This provides security.

3. Encourages betting confidence

Punters are more confident about betting on their preferred horse because they’re guaranteed the best possible value. BOG also promotes strategic betting, as bettors don’t rely heavily on the bookmaker’s initial odds.

4. Applies to various bet types

BOG typically applies to single and accumulator bets. This makes it a versatile offer for different betting preferences. It also encourages flexibility when betting on UK and Irish horse racing events. 

5. Ideal for volatile markets

Horse racing odds are famous for fluctuating rapidly. BOG ensures you benefit from favourable changes in odds, especially for events or races that are difficult to predict.

6. No minimum stake

Most BOG offers don’t require a minimum stake. This means you can qualify with any bet size. Whether a small wager or a larger one, the offer applies equally.

7. Enhances bet value

BOG ensures you get the best value for your stake. You receive an enhanced payout if the odds improve after you place your bet. This improves your chances of maximising profits.

Disadvantages of best odds guaranteed offers

From the above section, you can see the benefits of using BOG. Although they are great, certain limitations are still attached to this type of offer. To offer a balanced scale, here are five major disadvantages of placing a best odd guaranteed bet: 

1. Limited availability

Not all races qualify for BOG. Most bookmakers restrict it to UK and Irish horse racing. Certain events, like early morning markets, may be excluded. This limits how and where you can take advantage of the offer.

2. Single bookmaker restriction

BOG is bookmaker specific. You cannot combine offers across multiple sites. If a competitor offers better odds, you cannot benefit from both. As a result, there is the potential of missing out on higher payouts elsewhere.

3. No protection on lowered odds

BOG does not adjust if the odds drop after placing a bet. You only benefit when odds increase. This means you may lose potential value if the market moves against you.

4. Exclusions on bet types

Some bet types may not qualify. For instance, accumulators or each-way bets might be excluded depending on the bookmaker’s terms. This reduces flexibility for bettors who prefer complex wagers.

5. Promotional limitations

Bookmakers may cap stakes or limit winnings under BOG offers. There might also be restrictions on using free bets or loyalty bonuses. This prevents full exploitation of the offer.

Summary – The best odds guaranteed in the UK 

This guide shows why the best odds guaranteed offer is popular with British punters. There are a lot of benefits, such as increased payouts, reduced risks and safety from volatile odds. However, there are also drawbacks to note. The major one is the individual sportsbooks’ terms, as they have time frames and may cap wins. 

If you are searching for a BOG bookmaker, you can choose one from this guide. They have been vetted using the Sun Factor ranking system, so they are licensed, legit and offer a great user experience. Before choosing, it’s advisable to conduct independent research. This way, your selection matches your betting preference.

Lastly, gamble responsibly! Adhere to policies such as bankroll management and time limits. If gambling becomes a problem or an addiction, reach out to an organisation such as the Gambling Commission or the Responsible Gambling Council.
