Best Odds Guaranteed Bookmakers UK 2025
Best odds guaranteed offers are designed to give punters maximum value on their racing bets. Join us for a deep dive into how BOG works and learn which best odds guaranteed betting sites do it best.
What is Best Odds Guaranteed?
Best odds guaranteed (BOG) is a popular promotion offered by horse racing betting sites and greyhound racing bookmakers.
It ensures that if you place a bet at an early price on the day of a race and the starting price (SP) is higher, you’ll be paid out at the bigger price.
If the SP is lower than the odds you originally took, your payout remains based on the higher odds you locked in - giving you the best possible return every time.
This promotion is particularly valuable during major racing events like the Cheltenham Festival, where Cheltenham offers from top bookmakers often include BOG, to ensure punters get the best returns on their bets.

Best Odds Guaranteed in Action
Let’s say you’re backing a horse in the 3:30 at Cheltenham. You check the odds in the morning and see your selection is priced at 5/1. Confident in your pick, you place a £20 win bet with a bookmaker offering Best Odds Guaranteed.
Later in the day, just before the race goes off, the odds drift, and your horse is now available at 7/1.
- Without BOG – Your bet stays locked in at 5/1, meaning a win would return £120 (£100 profit + £20 stake).
- With BOG – Your bookmaker automatically upgrades your odds to 7/1, increasing your potential returns to £160 (£140 profit + £20 stake)—without you having to do a thing!
Now, imagine the opposite happens: you take 5/1 in the morning, but by race time, the horse is backed into 3/1. No problem—your bet remains at 5/1, so you still benefit from the higher odds you originally took.
Why BOG Matters
BOG gives you the best of both worlds—you’re protected if the odds shorten, and you get a boost if they drift.
It’s a no-brainer for any serious punter looking to maximise value on their horse racing bets.
Here’s why it makes a difference:
- Better payouts, automatically - If the odds improve after you place your bet, you’ll get the higher odds without having to do anything. This means you never miss out on extra winnings.
- Less worry about timing - With BOG, you don’t have to stress about placing your bet too early and missing out on better odds later. No matter when you bet, you’ll always get the best price.
- Works for accumulators too - In most cases, BOG doesn’t just apply to single bets but also to multiples, so you can enjoy the benefits across your entire bet slip.
Common Best Odds Guaranteed Terms & Conditions
The specific terms of Best Odds Guaranteed (BOG) can vary between bookmakers, but there are a few common rules you’ll find almost everywhere.
- Start Time: BOG only applies to bets placed after a certain time each day, which differs between bookmakers. If you place your bet before that time, you won’t qualify for the offer.
- Eligible Bet Types: Not all bets qualify for BOG. Ante-post bets, forecasts, tricasts, price boosts, and enhanced accumulators are usually excluded. Sticking to standard win and each-way bets is the safest way to ensure you’re covered.
- Rule 4 Deductions: If a Rule 4 deduction applies (when odds are adjusted due to a runner withdrawing), you’ll still get paid at the Starting Price (SP) if it’s higher than your adjusted fixed odds.
- Cash Out Restrictions: If you cash out a bet—whether partially or fully—it won’t be eligible for BOG.
- Free Bets: Bets placed using free bet stakes typically don’t qualify for Best Odds Guaranteed, so check the bookmaker’s terms before placing your wager.
By understanding these common terms, you can make the most of BOG and ensure you always get the best possible odds.
