William Hill Best Odds Guaranteed
Last checked:
Take a price on a race and if the starting price ends up bigger, you're paid at the bigger one. William Hill run their own version, and what decides whether it's worth anything to you is the small print rather than the headline. Here's theirs, read from the promotion itself.
What William Hill's terms actually say
- Not automatic: you need to be logged in or take a price marked as qualifying.
William Hill's wording, in full
“Online only. Opt-in req. Applies 08:00 day of race until start. Valid on Race Winner market. £25k daily cap applies to additional winnings. Full T&Cs apply.”
Quoted from William Hill's live promotion — “Best Odds Guaranteed on all UK & Irish Horse Racing”. Their own terms are the ones that count; we re-check this automatically.
What it's worth
It only ever pays you more, never less — if your price shortens you keep the price you took. A £10 bet at 5.00 that drifts to an 8.00 starting price:
Paid at the price you took
£50.00
Paid at SP (8.00)
£80.00
What the guarantee added
£30.00
Worked example only — it describes how settlement works and says nothing about whether a bet will win.

Things worth knowing about best odds guaranteed
- It applies to race-day bets, not ante-post
- Almost every bookmaker starts the guarantee at a set time on the morning of the race. A bet struck weeks in advance at a big price is an ante-post bet and normally sits outside it.
- It doesn't make a bad price good
- BOG protects you against a drift; it doesn't protect you against taking a short price in the first place. Comparing the price before you bet still matters more.
- Watch for “selected players”
- Several operators reserve the right to apply it only to some accounts. If the terms say selected players or selected races, check it's showing on your betslip before you rely on it.
