Best Odds Guaranteed decoded — which operators actually deliver

BOG explained: what the promise means, how to trigger it, and where the conditions catch you out.

What does Best Odds Guaranteed actually mean?

Best Odds Guaranteed (BOG) is a bookmaker commitment that protects the early-price bettor from a market that shortens before the off. The mechanics are straightforward: if you take an early price on a horse — say, 8/1 first thing in the morning — and the Starting Price (SP) at the time of the race is larger, for example 10/1, you are paid out at the SP rather than your early price. If your early price is larger than the SP, you keep the early price. Either way, you receive the better of the two.

The practical value of BOG is most evident in ante-post and morning-price betting on British and Irish horse racing, where market movements can be substantial. A horse trained by a big yard and backed heavily in the morning market may shorten from 6/1 to 4/1 by the off; without BOG you would lose 33% of your potential winnings. With BOG, the morning 6/1 is locked in as a floor.

Which operators on BELLE BUYS HOUSES LLC offer BOG?

Of the five operators reviewed on this site, William Hill and BoyleSports offer Best Odds Guaranteed. Betfair’s Sportsbook arm also offers BOG, though Betfair Exchange — the peer-to-peer market — operates differently and BOG is not applicable there. Unibet and 888sport do not offer BOG as of the most recent review cycle.

William Hill BOG — conditions

William Hill’s BOG applies automatically to all horse racing bets placed at an early price. Key conditions to be aware of:

  • Sport coverage: horse racing only (UK and Irish meetings). BOG does not apply to greyhound racing, football, or any other sport.
  • Meeting scope: UK and Irish fixtures covered. International racing (France, USA, Australia) is excluded.
  • Activation: automatic — no opt-in required. Any ante-post or morning price accepted on qualifying races is automatically BOG-eligible.
  • Must be logged in: the bet must be placed via your registered account. BOG does not apply to bets placed in a William Hill shop unless shop-specific BOG terms are active at the time.
  • Maximum stake limits: William Hill reserves the right to apply stake limits on individual markets. Very large ante-post bets may be subject to individual negotiation and BOG guarantees may not apply above certain thresholds. Always check the individual market terms.
  • Single bets and multiples: BOG applies to each qualifying selection in a multiple if each leg individually qualifies. The SP upgrade is applied leg by leg.
  • Each-way bets: the SP upgrade applies to the win portion only. Place terms are settled at the early price place odds; the place portion is not subject to BOG.

BoyleSports BOG — conditions

BoyleSports operates an automatic Best Odds Guaranteed policy that rivals the larger chains in sport coverage, with a particular strength in evening and all-weather cards.

  • Sport coverage: horse racing (UK and Ireland) and greyhound racing. BoyleSports is one of the few operators to extend BOG to greyhound racing, which is notable for value-oriented punters tracking evening Bags meetings.
  • Meeting scope: UK and Irish fixtures for both codes. International horse racing is excluded.
  • Activation: automatic for registered account holders. No opt-in or special code required.
  • Must be logged in: bets must be placed via your BoyleSports online account.
  • Maximum stake limits: BoyleSports applies standard stake restrictions and may cap individual market exposure. Very large early-price requests should be verified with customer services for BOG confirmation.
  • Each-way bets: as with William Hill, the SP upgrade applies to the win portion only.

How to use BOG effectively

The key insight for getting value from BOG is timing. Early prices — those available first thing in the morning, sometimes the evening before a big meeting — tend to be the most generous because the bookmaker is pricing with less certainty about likely market support. By contrast, the SP reflects the full weight of money and is often a reliable indicator of the “true” probability.

The optimal strategy for BOG is to take morning prices on horses where you expect the market to shorten significantly — well-fancied runners from major stables, horses with strong form in the right conditions, or handicappers likely to receive stable support. If the horse shortens, you keep your early price. If something unexpected lengthens it (a fitness concern, a soft market), your BOG means you collect at the larger SP. In either direction, you cannot lose relative to SP.

When BOG does not apply

Several circumstances reliably exclude a bet from BOG coverage, regardless of operator:

  • Non-runners: if a selection is withdrawn from a race before the off, the bet is void and stake returned. BOG is irrelevant in this scenario.
  • Each-way place portions: as noted above, the place portion of an each-way bet is typically settled at early-price place odds, not BOG-adjusted.
  • Unnamed favourites / field bets: ante-post bets taken against “unnamed favourite” or “the field” are not eligible for BOG at most operators.
  • Free bet stakes: BOG upgrades typically apply to cash bets only. If your stake is a free bet token, the SP upgrade may not apply; read the free-bet terms carefully.
  • Bets placed after the off: BOG only protects early-price bets. In-play or “starting price” bets are settled at SP by default and BOG is not applicable.
  • Accounts with restrictions: operators may restrict BOG on accounts that have been identified as bonus-abusing or that have been placed on reduced-payout terms. If you are in doubt about your account status, contact customer services before placing.
