Best Odds Guaranteed Bookmakers UK 2026

What Is Best Odds Guaranteed?

Best Odds Guaranteed (often shortened to BOG) is a horse and greyhound racing offer that pays your bet at the higher of the early price and the Starting Price (SP) if it wins. If the SP is shorter than the price you took, you keep the higher early price, so you always get the better of the two on winning bets.

It is usually applied to win and each-way bets on selected horse and greyhound races. It only improves returns on winning selections; losing bets are simply settled as losers with no change.

Example of Best Odds Guaranteed

1. You backed a horse for £10 at odds of 4/1 earlier in the day on a race that has Best Odds Guaranteed.
2. By the off, the horse has drifted, and its official Starting Price is 6/1, and the horse wins the race.
3. Without BOG, you would be paid £40 profit (4 × £10). With BOG, the bet is settled at 6/1, so you receive £60 profit instead (6 × £10), plus your £10 stake back.

It pays to find out which bookies do best odds guaranteed before placing a bet on specific races, as some operators can offer enhanced odds that increase potential winning value.

Best Odds Guaranteed Bookie: Betway

If you’re looking for the bookmakers with best odds guaranteed promotions, we’ve managed to identify our top pick for you

Betway is the best betting site with the best odds guaranteed promotions.

A reputable sportsbook in the UK, Betway provides bettors with the opportunity to secure the SP if better than the EP early on the day of the race. It is worth noting that the promotion excludes all Extra Places races

The UK & IRE horse racing markets offered at Betway are among the best in the UK, with the BOG offer providing additional value on top of the competitive odds that are consistently provided to registered punters.

It is important to note that these can change over time, so we recommend you keep a close eye on them to avoid any nasty surprises. For instance, the daily activation window may change from 09:00 to 10:00 GMT.

Best Odds Guaranteed Times

Best Odds Guaranteed (BOG) times are the hours on race day during which a bookmaker will apply BOG to your horse/greyhound bets, and these windows vary by bookie.

Most bookies switch BOG on from a set morning time (often 8-10am) up until the off, and bets placed outside that window will not qualify. BOG only applies to bets placed on the day of the race, not to ante‑post bets.

Check out the BOG time that is available at our recommended top bookies below:

• BetVictor: 09:00 GMT
• Betway: 09:00 GMT
• QuinnBet: 10:00 GMT

How We Rate and List the Best Odds Guaranteed Bookmakers

At Mr. Gamble, our team of experts determines the ranking and list of BOG bookmakers by following a strict methodology.

We carefully consider several factors at each site we review, ensuring you receive an unbiased and accurate opinion informed by expert thinking. Among the factors we analyse are:

BOG Market Coverage

We check out the BOG market coverage when ranking and listing our recommended bookies. We look at the range of markets offered and the value that can be provided.

Many bookies offer horse racing best odds guaranteed promotions, but that doesn’t mean they are the best. We compare those who do to maximise the value you can obtain.

BOG Activation Window

At Mr. Gamble, we closely examine the BOG activation window. As detailed earlier, some bookies can open their windows as early as 08:00 GMT. However, some may not open them until hours later, such as at 10:00 GMT. These two hours can make a huge difference to punters; we make sure to recommend and list those that give you plenty of time before a race may start.

Payout Limits

We analyse the payout limits that may be imposed on BOG offers. Most bookies will limit how much can be won from the uplift (odds that have moved). However, not all of them will impose the same restrictions. Some bookies can cap winnings at a higher amount than others, helping these betting BOG sites to rank better than others.

Transparency of Terms

Are the terms and conditions of the BOG offer clear? At Mr. Gamble, our experts rank betting sites BOG is offered based on the transparency of these promotions. We consider how clear and easy the rules are to understand, as these promotions can be laced with specific terms that are easy to misunderstand or miss.

Consistency of BOG Availability

Does the bookie consistently make BOG offers available? Those who do will be rated higher at Mr. Gamble, as it means you can receive more potential value when betting as a bettor. It may not be available at every race, but the top bookies will often offer it for the biggest meets. If this is the case, our experts will have listed the site positively.

BOG Betting Markets

If you want to bet in the UK with the best odds guaranteed offers, you’ll likely only find bookies offering them across horse racing and greyhound racing events. In rare cases, you may find a sportsbook offering football bets as a promotional offer; these are usually very restrictive as they come with several terms and conditions. Enhanced odds are more common than BOG in football betting.

Best Odds Guaranteed Horse Racing

The best horse racing betting sites at Mr. Gamble regularly feature BOG promotions. UK horse racing is the core market for this promotional offer. You can find it available for UK and Irish races, giving you ample betting opportunities to enhance the potential returns when selecting a winner.

In UK and Irish horse racing, you can find odds ahead of the day of the race. This is known as the early price (EP). With BOG offers, you can bet on the day of the race from the activation window on the odds that are shown, and still receive the best odds if they drift ahead of the race.

For example, you may take a horse at 4/1 after 10:00 GMT on race day. If the odds drift to 6/1 before the race starts and it wins, you’ll receive a payout at 6/1 because of the offer. Some bet types may be ineligible, as the promo applies only to win-only and each-way markets.

Best Odds Guaranteed Greyhounds

Another popular market at UK bookmakers that offers BOG is greyhound racing. It is the second most common BOG market in the UK and essentially replicates horse race betting in its workings. You need to place a bet on the same day as the race and after the activation window to benefit from any odds that may drift before the race starts.

The best greyhound betting sites allow you to watch the biggest greyhound races through live streams and telecasts they have, enabling you to maximise the value that can be obtained. It’s important to make sure you recognise and satisfy the terms and conditions, as these can vary at each sportsbook.

Best Odds Guaranteed Football

A best odds guaranteed bookie may offer the promotion for football betting. However, it's extremely rare and isn’t something new UK customers should always expect to see. The best betting sites may offer it on specific matches, but it’s important to recognise that this isn’t the norm. Enhanced odds and odds boosts are more common for football betting.

Common Terms and Conditions for BOG Promotions

BOG promotions come with many common terms and conditions you must be aware of. These include:

• Opening Time: “Opening Time” is when BOG starts applying on race day, e.g. from 8am, 9am, or 10am until the off, with any bets struck before that time not qualifying for BOG.
• Bet Type: The “Bet Type” section states which bets qualify, typically fixed‑odds win and each‑way singles (and sometimes multiples) on UK/Irish horse or greyhound racing.
• Cash Out: Most T&Cs state that bets fully or partially Cashed Out do not benefit from BOG, because the bet is settled early at the cash‑out value rather than the SP. This policy is standard across the best online betting sites with cash out.
• Rule 4: The Rule 4 clause says standard non‑runner deductions still apply to your bet, and BOG is then applied to the post‑deduction price if the SP is higher.
• Each‑Way Terms: Each‑way place terms (e.g., 1/5 odds, 3 places) are fixed by the race terms, and BOG only affects the win part of the bet unless explicitly stated otherwise.
• Payout/Benefit Cap: A “maximum benefit” clause caps the extra BOG uplift per customer, per day, or per bet (for example, £1,000, £10,00,0 or £25,000 in additional winnings).
• Minimum/Maximum Stake: Some betting sites specify minimum stakes (e.g., £1 win / 50p each‑way) and occasionally cap stakes on races or customers for which BOG is available.

Why Bet at Best Odds Guaranteed Betting Sites

Best Odds Guaranteed (BOG) means that when you back a horse early with a BOG bookmaker, your winning bet is always settled at the better of the price you took or the official Starting Price (SP). This turns price moves in your favour on winners without ever making them worse.

Odds move because money, information, and market sentiment change through the day: money arriving, going, or reacting to going changes, jockey switches, tip coverage, and trading. If you bet early at 4/1 and the horse drifts to 8/1, without BOG, you are stuck on 4/1 and effectively “sold” your winner too cheaply, but with BOG, you get paid at 8/1 instead.

Think of BOG as a built-in edge that only kicks in when the SP is bigger than your early price, while never hurting you when the SP is shorter. Examine the table below to visualise the value being offered when using BOG offers compared against when it isn’t being used in a simplified way:

Odds can appear in more complex forms (11/8, 4/6, 7/4, etc.), but using a betting odds calculator can help you to work out what odds are greater/shorter than those to see if you benefit from the promotion.

Why This Matters Long Term?

It is recommended to bet with a BOG bookie due to the additional value available. Essentially, you’re leaving money on the table when you do not use a bookie that has BOG promotions, especially as odds can change frequently in the lead-up to a race on the day.

By using BOG, you can increase the potential profits returned over a longer period. This can help you to prolong gambling sessions further, as it can increase your bankroll.

Betting Promotions To Use When BOG Is Not Available

If BOG isn’t available as a promotion for a specific sports market that you want to bet on, it’s possible to find a different type of bonus that may be used. Some bonuses are more versatile and expansive compared to best odds guaranteed promotions, including the following…

Free Bets

Free bets are widely offered by bookies. You may find sites with betting apps with a sign up bonus that can be used to claim this promotion. 

Free bets are exactly what they say they are: bets that can be placed without risking any real money. You may have to make a qualifying deposit and place a bet on min odds. Can be ideal for betting at online football betting sites UK.

No Deposit Free Bets

A sportsbook free bet no deposit can be more difficult to find, but they are available. This works the same as a free bet offer, but without the requirement to deposit funds first. These are completely risk-free. 

Again, sports free bets are typically available across various sports and events; horse and greyhound racing (not alongside BOG) may be possible to wager on.

Enhanced Odds

Several bookies continue to offer punters enhanced bets odds when using their sportsbook. It’s a common promotion and can be available to bettors as frequently as BOG promotions. Almost all sports can benefit from bet boosts, but they will be at the discretion of the bookmaker and whether they choose to inflate specific odds. You won’t often find odds boosts available on BOG races, but it can happen.

Acca

Acca free bets or acca insurance offers are widely available at many UK sportsbooks, with this bet type hugely popular with British punters. You can find the best acca insurance offers at Mr. Gamble; this offer lets you get your stake back if one of your selections lets you down in an acca of 4+ bets. Football betting tends to benefit more from this promotion than others.

Best Odds Guaranteed: Pros and Cons

Best Odds Guaranteed (BOG) mainly offers upside on winners by paying the better of the early price or SP, but it also comes with limits and restrictions that matter to regular bettors.
