Best Odds Guaranteed Bookmakers in the UK – Best Sites for BOG

Best Odds Guaranteed is one of the most valuable promotions in UK horse racing betting and protects you if the odds on your selection drift after you’ve placed your original bet.

With BOG, if the eventual Starting Price (SP) of a horse is bigger than the odds you initially took, the bookmaker pays out at the higher SP instead, ensuring that you don’t miss out on better value.

In this BetIdeas guide, we explain exactly what this perk means, how it works in practice, which bookmakers still offer it, the key terms and conditions involved, as well as the practical strategies you can use to make the most of it.

What Does Best Odds Guaranteed Mean & How Does It Work?

In stripped-back terms, BOG ensures you always receive the best possible payout on your winning selection, no matter how your horse’s price changes on the day of the race.

You place your bet at a fixed price (after the qualifying time, typically from 8am on race day) and if the horse shortens in the market and the Starting Price (SP) is lower, you keep your original higher price.

But if the price drifts and the SP returns are potentially bigger, the bookmaker automatically upgrades your payout to the superior SP.

This “extra” profit from the drift goes on top of your standard winnings (subject to the bookmaker’s daily cap on additional benefit.

The beauty of this sweetener lies in its risk-free upside, as it protects against price movement in your favour while safeguarding the price you originally secured.

It’s especially useful on race day when morning prices can fluctuate due to late money, non-runners, or market variables. Next, let’s take a look at a real-world example for further clarity:

Take Galopin Des Champs for the Cheltenham Gold Cup, for instance. In the morning, he’s trading at 5/4 (1.25 in decimal) and you back him at that price once the window opens (e.g. 8am).

By the off, support has drifted away, however, and he goes off at 7/5 (2.4 decimal) SP.  Without the guarantee, your winning bet pays at 5/4. For a £100 stake, profit = £125, total return = £225.

However, with the perk applied, you’d get paid at the bigger 7/5 after the race result thanks to the bookmakers’ price guarantee (profit = £140, total return = £240. Aan extra £15 profit purely from the drift).

Popular Best Odds Guaranteed Bookies

A large number of popular bookie brands run best odds deals for Irish horse racing in the UK. Below we’ve listed the leading operators, with information on current activation times, caps and how each firm approaches their own format:

William Hill Best Odds Guaranteed

William Hill best odds guaranteed time: 8am on the day of the race

A solid, reliable option for regular punters, William Hill’s BOG is now available from 8am (rolled back in January 2025) on all UK & Irish horse races. You’ll need to opt in via the horse racing homepage and the offer is invite-only for some accounts.

Maximum additional benefit is £/€25,000 per customer per calendar day. It applies to win singles and multiples placed using the best odds guaranteed William Hill deal. Ante-post, Tote, each-way extra and in-running bets don’t apply, meanwhile.

Virgin Bet Best Odds Guaranteed

Virgin Bet best odds guaranteed time: 10am on the day of the race

At Virgin Bet, their BOG promo on all UK & Irish horse racing starts after 10am. The maximum increase in returns is capped at £50,000 per customer per day.

It covers win and each-way bets but excludes ante-post, in-running and cashed-out bets. A generous cap makes it attractive for bigger stakes, though the later start time is a slight drawback compared with 8am operators.

In addition, you must stake £25 or more on the sportsbook in a 7-day rolling period to qualify and if you haven’t met the threshold, the bonus will no longer be visible or active to you.

Unibet Best Odds Guaranteed

Available from: 8am on the day of the race

Unibet rolls out their promo from 8am on selected UK & Irish races (singles and multiples) each day. Daily maximum possible return is £25,000. Exclusions include ante-post bets, Tote, enhanced prices and in-play.

The offer is only open to residents of the UK, Ireland and Belgium, however. This is largely a clean, straightforward offer that comes without strings or complications. Its sunrise start makes it ideal for those who like to bet early on ITV races.

Paddy Power Best Odds Guaranteed

Paddy Power best odds guaranteed time: 8am on the day of the race (opt-in required)

The Paddy Power BOG deal comes in from 8am once you remember to opt in on their dedicated promotions page. It applies to win/ew singles and multiples on UK & Irish racing only and there is a raft of exclusions, including best placed with free bets, wagers placed ante-post, Power Price selections.

The maximum payment is £/€1,000 per customer per day here is also way lower than you’ll find elsewhere. That means that this one is likely to be more popular with recreational punters and the low cap limits with the best odds guaranteed Paddy Power promo could make it less appealing for serious bettors.

Ladbrokes Best Odds Guaranteed

Available from: 8am on the day of the race

Ladbrokes offers a price guarantee on all UK & Irish horse racing (singles and multiples) from 8am. Maximum additional benefit is £/€10,000 per day, which is less generous than the terms offered by some of their prime competitors.

Markets like ante-post, Tote/pools, pari-mutuel, enhanced price, betting without place only (top 2/3/4 finish) are all excluded, but that’s nothing out of the ordinary. This Ladbrokes BOG promo is also an automatic opt-in deal, so you don’t have to worry about checking boxes when you log in.

Coral Best Odds Guaranteed

Available from: 8am on the day of the race

The Coral BOG runs from 8am on UK & Irish horse racing and you must be a resident in one of those regions to take part. A £10,000 daily cap per customer applies, which is largely in line with the figures other operators set.

The usual market exclusions apply, similar to the ones listed for brands above. You are automatically opted into this one when you place a win or each way single or multiple bet, so Coral earn extra points for handiness.

BoyleSports Best Odds Guaranteed

Available from: 8am on the day of the race

BoyleSports pays out at the better of your taken price or SP on UK & Irish horse racing after 8am on the day. The maximum bonus attached is a chunky £50,000 per customer per day, making it one of the highest caps in the industry. There is a much lower €/£1,000 cap for bets placed in retail outlets on the high street.

No opt-in is required either, while there is nothing untoward to be concerned about in the exclusions. That coupled with the high upper limits and early start, makes this version of the promo one of the best we’ve encountered.

Betway Best Odds Guaranteed

Available from: 9am on the day of the race

Capped at £25,000 daily per day, Betway guarantees odds on UK & Irish racing (win bets in extra-place races are eligible), making it a solid mid-tier option with a respectable cap.

The promo doesn’t apply to promotions will not work on ante-post bets, combined odds, total odds, overnight, place only, and matched wagers. Again, that’s nothing out of the ordinary, however.  This is another one that opts in automatically, which we like.

BetVictor Best Odds Guaranteed

Available from: 9am on the day of the race

This firm caps their maximum daily benefit per customer to £/€10,000, placing it near the wrong end of the spectrum in terms of attractiveness. Like the others, this applies to UK and Irish racing only, with international meetings and the usual set of excluded markets similar to restrictions found elsewhere.

The low max cap here will put off high rollers, however, it’s still large enough to suit most punters. The quality of BetVictor’s excellent overall horse racing coverage will attract plenty of bettors to the platform.

BetGoodWin Best Odds Guaranteed

Available from: 10am on the day of the race

BetGoodWin is a popular destination for racing punters in the UK, though their offer falls quite a bit short of alternatives elsewhere in terms of value. First, their £/€1,000 cap is modest compared to others, to say the least.

The later start time of 10am might not feel that significant, though opening the offer later than competitors each day does feel like a strange call and will likely lose them business. Ante post betting, special markets and international racing are all excluded too, though opt-in is automatic.

Pros & Cons of BOG on Horse Racing

In the name of transparency and fairness, we’re going to take a look at some of the pros and cons of Best Odds Guaranteed promos now, though they are very much weighted in the former category. Below, we break down the key advantages and drawbacks in greater detail.

Best Odds Guaranteed Times

The best odds guaranteed bookies kick things off at different times each day, while each vendor also applies different daily caps to their promos. See the table below for comparison:

Key Terms & Conditions for BOG Bookie Deals

While the offer is largely a straightforward and punter-friendly promotion, every bookmaker applies a specific set of rules to keep their offers fair and sustainable.

These terms are broadly similar across most of the firms featured on BetIdeas and others, but there are variations in the fine print, so reading through T&Cs is essential. Here are some of the most common terms and conditions you’ll encounter:

• Bets must be placed after the stated time on race day (typically between 9am and 10am, depending on vendor). Early morning bets before the window often settle at the taken price or SP without the guarantee applying.
• Only real-money bets qualify — Free bets, bonus funds, Power Prices/enhanced odds, cash-out bets, partial cash-outs and bets using tokens or promotions are usually excluded.
• Applies to win and each-way bets (where stated) — Most cover standard win singles, each-way and multiples, but only on the win part for each-way, while others limit to outright win markets.
• Rule 4 deductions are applied before comparing prices — If a non-runner triggers Rule 4, the adjusted SP is used for the odds comparison, ensuring fairness.
• Non-runners usually settle at SP (guarantee may not apply) — If your selection becomes a non-runner, the bet often voids or settles at SP without the guarantee kicking in.
• Maximum additional winnings cap per customer per day — This limits the “extra” profit from odds drifts.
• Exclusions apply — Ante-post bets, pool/Tote wagers, forecasts/tricasts, place-only markets, in-running/live bets, and non-UK/Irish races (e.g., France, USA) don’t qualify.

Other frequent restrictions with best odds guaranteed bookie companies include no application to betting without the favourite, insurance bets or certain enhanced place offers. Some bookies require manual opt-in via the promotions page to take part, too.

Why Have Some Bookmakers Withdrawn BOG?

Several prominent UK bookmakers (including Betfair Sportsbook), have discontinued best price guaranteed on horse racing and greyhounds.

The Betfair best odds guaranteed promotion was removed entirely by the firm from its sportsbook in October 2023, with customers directed toward its Exchange platform instead, where better prices are often available without the need for extra concessions.

Other operators have also pulled or restricted guarantees, either fully or partially. The primary motivations behind these withdrawals are rising operational costs and squeezed margins.

However, compounding this, the UK government’s gambling tax reforms, including the steep rise in Remote Gaming Duty (from 21% to 40% effective April 2026), have put extra pressure on bookmakers’ profitability.

Firms argue these “punters’ taxes” force reductions in customer-friendly offers like BOG to offset the burden, though racing-specific betting duty on UK/Irish horse racing remains unchanged for now. Punters are advised to shop around for the strongest remaining offers.

Most Popular Events for Best Odds Guaranteed in Horse Racing

Price guarantees deliver the biggest value during major UK and Irish horse racing festivals, where large fields, public betting, non-runners and late market moves frequently cause big price drifts.

These top-tier meetings are known for producing dramatic, early morning price swings, turning BOG betting into a powerful tool for nabbing extra profit on drifters.

Below are some the standout events from the racing calendar where punters benefit most from this betting perk.

Cheltenham Festival (especially Gold Cup day)

Cheltenham is the pinnacle of National Hunt racing, with more than 20 races over four days in March each year. The highlight is the Cheltenham Gold Cup on the final day, which is often a volatile betting market due to ante-post favourites drifting or shortening.

Massive crowds and media attention amplify price swings here, making horse racing best odds guaranteed promos especially lucrative for the race, and similarly for the other common extra place races like the Ultima Handicap Chase or County Hurdle, where outsiders can drift substantially for enhanced returns.

Grand National Meeting at Aintree

This world-famous steeplechase, contested every April, is probably the most recognisable race on the planet. It’s a massive betting event and draws huge wagering volumes each year, with prices on longer shorts often drifting wildly due to late non-runners or public sentiment.

BOG shines here across the three-day festival, particularly on the National itself, where market movement can turn a solid early price into a much bigger payout.

Epsom Derby

The Derby Festival runs in early June each year, with the Derby, the headline act and flat race of enormous prestige. This classic over the unique Epsom Downs invites flurries of ante-post interest, but race-day money and non-runners frequently push odds in all kinds of directions, particularly in markets for the Derby itself and the Oaks.

With the bookmaker’s odds guarantee, any early bets receive protection, while extra value also available when favourites ease in the betting.

Royal Ascot

Royal Ascot 2026 spans five days of elite flat racing with royal pageantry in June every year. Key highlights include the Queen Anne Stakes, King Charles III Stakes, Prince of Wales’s Stakes and Gold Cup.

The Group 1s here can see large, dramatic price drifts in the markets. The Best Odds promotion excels again for the big handicaps too, where gamble develop from early prices, opening up avenues towards bigger returns.

Glorious Goodwood

The Goodwood Festival runs from late July through to early August every 12 months and includes five glorious summer days of racing on the Sussex Downs.

Iconic races like the Sussex Stakes and Goodwood Cup see sharp market moves from holiday crowds and the usual tranches of late money. Bookmakers best odds guaranteed betting offers are highly effective weapons here, especially on wide-open handicaps where prices dance about, turning race-day bets into improved payouts.

Ebor Festival at York

The Ebor Festival at York Racecourse takes place in August and features the prestigious Ebor Handicap on the final day of the meeting.

The Juddmonte International (Wednesday), Yorkshire Oaks (Thursday) and Ebor Handicap (Saturday), among others, often spark volatility in the betting markets, and price guarantees can add real value, with odds in a constant state of fluctuation on race day.

Irish Derby and Punchestown Festival

This event at the Curragh usually falls in late June/early July, and draws top European three-year-olds in a classic prone to market swings with influence from international raiders.

The Punchestown Festival meanwhile, emerges in spring, closing the jumps season with Grade 1s like the Champion Chase and Gold Cup. Both deliver strong BOG opportunities through large fields and late drifts, especially at Punchestown where end-of-season form can shift prices sharply.

Effective BOG Tips & Strategies

Best price guaranteed is better than a mere safety net. When used in the right way it can be a powerful edge. Here are five practical strategies, provided by our team of experts at BetIdeas, that you can use to get the most from the promo while using our UK and Irish horse racing betting tips.

Bet early but after the window opens

The key here is to act as soon as the promotion activates (the Paddy Power BOG time is 8am, for instance). Place your selections right after this time on televised/ITV races, where prices are often sharpest early. This can help you to nab competitive morning odds while fully qualifying for the promotion. If the horse drifts later due to non-runners or market moves, you automatically get the higher SP payout.

Combine with price boosts

Many operators run early boosts or enhanced odds on selected races that still qualify(always check terms to confirm). Take the boosted price after the window opens, then enjoy the extra benefit if it drifts further to a bigger SP. For example, a boosted 5/1 becomes 6/1 SP payout.

Use on each-way outsiders

Longshots and mid-range each-way contenders frequently have drifting prices in large fields, especially handicaps. It protects the win portion of your each-way bet if the price lengthens, boosting overall returns significantly when the horse places or wins. Focus extra place races where possible (e.g. 5 or 6 etc.).

Shop the early price across multiple bookies

Don’t settle for one bookmaker. Compare early prices from 8am onward across all qualifying betting sites. Grab the best available fixed price on your selection, then let the offer handle any drift. Tools like odds comparison sites help spot the top offer quickly. This “price shopping + deal” combo often yields the highest effective odds.

Monitor Rule 4 races

In races affected by non-runners, a Rule 4 deduction reduces odds proportionally. Most bookmakers apply the adjusted SP for comparison, so check post-non-runner if your taken price still holds value. If the deduction is small and your horse drifts anyway, the promo can still deliver extra profit. Always review the final SP settlement terms for your bookie.
