Best Odds Guaranteed Bookies UK

Last Updated on March 5, 2026 by author

Imagine placing a bet on a horse at 4/1, only to see it start the race at 6/1. Without Best Odds Guaranteed (BOG), you’d miss out on those extra winnings. BOG is a popular promotion offered by many UK bookmakers, ensuring you’re paid at the higher of the odds you took or the starting price (SP) if it’s better. This guide explores what BOG is, how it works, and which UK bookmakers offer the best BOG deals in 2025, helping you make informed betting choices.

What is BOG?

BOG is a bookmaker concession primarily for horse racing, though some extend it to greyhound racing. If you place a bet at a fixed price and the SP is higher, you’re paid at the higher odds. For example, a £10 bet at 3/1 that wins at an SP of 5/1 would return £50 instead of £30 (plus your stake). This promotion protects bettors from odds fluctuations, making early betting more appealing.

Why BOG Matters

BOG is a game-changer for bettors because it eliminates the risk of missing out on better odds. Horse racing odds can shift dramatically due to market movements, and BOG ensures you get the best possible payout. It’s especially valuable during major events like the Cheltenham Festival or Grand National, where odds can be volatile. By choosing a BOG bookmaker, you’re securing better value without needing to monitor odds constantly.

How BOG Works

Here’s a simple example:

• You bet £20 on a horse at 4/1 with a BOG bookmaker.
• By race time, the SP is 6/1.
• If your horse wins, you’re paid at 6/1, earning £120 (plus your £20 stake) instead of £80.

If the SP is lower (e.g., 2/1), you still get your original 4/1 odds. BOG only applies to win and each-way fixed odds bets, typically excluding ante-post, Tote, or in-play bets. Most bookmakers offer BOG from a specific time on race day, such as 8am or 9am.

Benefits of BOG

• Maximizes Returns: Ensures you get the highest possible payout.
• Encourages Early Betting: You can bet early without worrying about odds drifting.
• Covers Multiple Sports: While mainly for horse racing, some bookmakers include greyhounds.
• Enhances Strategy: Pairs well with other promotions like extra places or free bets.

The History of BOG

BOG emerged as a competitive tool in the early 2000s as online betting grew, with bookmakers like bet365 and William Hill popularizing it to attract customers. It became a standard feature among major UK bookmakers, though some, like Betfair Sportsbook, have since withdrawn it. The promotion reflects the industry’s shift toward customer-friendly offers, ensuring bettors get fair value in a dynamic betting market.

Expert Insights

Industry experts emphasize BOG’s value for long-term profitability. According to a Racing Post article, bet365’s combination of BOG and price-matching on ITV races makes it a top choice (Racing Post). Professional bettors often prioritize bookmakers with early BOG times and no payout caps to maximize their edge.

Case Studies

• Cheltenham Festival: A bettor placed £50 on a horse at 5/1 with bet365. The SP was 8/1, resulting in a £400 payout instead of £250, thanks to BOG.
• Greyhound Racing: Using Coral’s BOG, a £20 bet at 3/1 paid out at 5/1 SP, earning £100 instead of £60.
