Best Odds Guaranteed — Every UK Bookmaker With BOG
Best Odds Guaranteed (BOG) is the single most valuable promotion in UK horse racing betting. If you back a horse at an early price and the Starting Price (SP) returns bigger, a BOG-enabled bookmaker pays you out at the bigger price. It’s free value, applied on every race you back, and over a season it compounds into the biggest “edge” most recreational punters will ever get from a bookmaker.

How Best Odds Guaranteed Works — a Worked Example
Say you back Constitution Hill at 3/1 (taken odds 4.00) to win the Champion Hurdle at 10am on race day. You stake £10 win singles.
- Scenario A — The horse drifts. Constitution Hill returns at SP 4/1 (5.00). Your BOG-enabled bookmaker pays you £40 profit instead of £30. You keep £10 extra.
- Scenario B — The horse shortens. Constitution Hill returns at SP 2/1 (3.00). You still get paid at your taken 3/1 price — £30 profit. The “guaranteed” part is one-way.
- Scenario C — Non-runner. The horse doesn’t line up. Stake is refunded. (Ante-post NRMB applies earlier; same-day NR rules kick in from the time BOG applies.)
In other words: BOG is always in your favour. You never lose value, you sometimes gain it.
Why BOG Matters — the Maths
BOG’s impact is counterintuitively large. Imagine 200 bets over a season at a £10 stake, at an average taken price of 5/1 (6.00). If 30% of those bets drift by just one full point by the off (e.g. 5/1 becomes 6/1, 7/1, or 8/1), BOG pays out, on average, an extra £15-25 per drifting winner. Over a season that’s £150-300 of extra value — for doing nothing.
Compared to “price boost” tokens (limited to one bet each), “free bet” promos (requires a losing qualifying bet), or loyalty rewards, BOG is the most efficient bookmaker concession — because it applies on every eligible bet, automatically, with no opt-in.
Terms Variations by Bookmaker
Every operator in the table above offers BOG, but the small print varies. The five things to check:
1. Start time
Most firms start BOG from 8am or 9am on race day. Bet365, William Hill and QuinnBet are the earliest (8am for UK/IE racing). BetMGM starts at 10am, which slightly reduces the drifting-price window.
2. Markets covered
All major firms cover UK and Irish horse racing. Some (Bet365, William Hill) extend BOG to French, South African or Australian racing. Check each bookmaker’s specific list.
3. Bet types
Singles are always covered. Doubles and multiples are usually covered but with exclusions — some firms apply BOG to multiples only if every leg is horse racing, not mixed-sport accumulators.
4. Maximum payout cap
Some firms cap BOG payouts at £1,000-£2,000 per bet. This rarely affects recreational punters but matters if you’re staking more than £100 on big-price selections.
5. Exclusions
Common exclusions: antepost bets (BOG does not typically apply to bets struck before the 48-hour declaration window), Enhanced/Boosted prices (if you take the boost, BOG doesn’t stack), and bets placed via exchange platforms.
When BOG Delivers Most Value
Big festivals
At Cheltenham, Aintree, Royal Ascot and Epsom Derby, the weight of money arrives late and markets move significantly in the final hour. Horses drift 2-4 points regularly. BOG value is at its peak during festival week.
Drift-prone races
Maiden hurdles, novice chases, bumpers and small-field point-to-point races have thin markets that move dramatically on race-day gossip. Back at the 10am show and let BOG do its work.
Getting on early
BOG punishes people who wait until the off. Take your price at 10am — the SP can only equal or beat it (from your perspective). If you wait until 2pm you’ve lost the entire BOG window.
Common BOG Gotchas
- Enhanced price selection. If you choose a “boosted” price (e.g. 5/1 boosted to 6/1), you usually lose BOG on that bet. You’ve already taken the best value.
- Non-runner rule-4 deductions. When a horse is withdrawn after your bet is struck, Rule 4 deductions apply — your taken price is reduced. BOG applies to the adjusted price, not the original.
- BSP vs. ISP. Most firms use Industry SP. Some exchange-based books use Betfair SP for BOG calculation.
- Account restrictions. Winning punters are regularly restricted, which can include BOG removal. This is an unavoidable reality of the market.
Frequently Asked Questions
What does Best Odds Guaranteed mean?
If you back a horse at an early price with a BOG-enabled bookmaker, and the Starting Price returns bigger, the bookmaker pays you out at the larger of the two prices. You always get the better outcome.
Does BOG apply to ante-post bets?
Typically no. BOG applies from the moment the race-day market opens (8am-10am depending on the bookmaker), which is after the ante-post market closes. Ante-post bets have their own protection (Non-Runner Money Back at most firms).
Does BOG apply to multiples?
It depends on the bookmaker and the selection. Horse-racing-only multiples are usually covered; mixed-sport multiples vary. Check the specific operator’s BOG terms.
Can I combine BOG with a free bet?
Yes — most bookmakers apply BOG to bets placed with free-bet tokens, though some exclude free-bet stakes from enhanced-odds calculations. Read the token’s terms.
Which bookmaker has the best BOG terms?
Bet365, William Hill and Betfred have the earliest start time (8am), broadest market coverage (UK + IE + select international) and longest track record. For sheer reliability and payout speed, these three set the standard.
Do exchanges offer BOG?
No. Betting exchanges (Betfair, Smarkets) offer peer-to-peer markets without a bookmaker acting as counterparty, so there’s no “guarantee” to offer. On an exchange you trade the market directly — see our exchange betting guide.
