What does Best Odds Guaranteed mean? | BOG guide for punters in 2026

Best odds guaranteed (BOG) is a type of sports betting promotion where your winning bet will get paid at the higher of the odds you took or the official starting price (SP) at the off. It is mostly a horse racing betting feature, though some UK bookies like Coral, Ladbrokes, and BoyleSports also offer it on greyhound racing.

In this guide, you’ll learn how it works, which bets count, the typical T&Cs to watch out for in 2026 and which UK bookmakers offer best odds guaranteed. I’ll also walk you through some concrete and timely examples.

What is Best Odds Guaranteed? Explained for new punters

In the simplest terms, Best Odds Guaranteed is a type of offer that gets your winning bet the best possible payout when you lock in a price early. I touched on this briefly in my betting odds guide. Here’s how it works in practice:

1. Place a bet before the start of the event (primarily applies to horse racing).
2. If the event starts and the Starting Price is higher than it was when you placed your bet, you’ll get the higher odds. If the odds are lower, you keep the price you already have.

Important note: Bookmakers have different times and deadlines for when BOG is available.

Platforms like BetGoodwin, BetVictor, CopyBet, and Grosvenor apply BOG once you place a qualifying bet. Others like Ladbrokes, Paddy Power, and Coral require a one-time opt-in via the promotions page. A few bookies restrict it to loyalty scheme members, such as Sky Bet, which limits the offer to its Sky Bet Club members.

What is the Starting Price (SP)?

In the simplest terms, the Starting Price (SP) is the price (odds) at the moment a race begins. It’s calculated from the on-course betting market at the off.

For SP, you will be paid odds at the precise instant the stalls open or the tape rises. Best odds guaranteed on horse racing offers compare the price you took against the SP at the same bookmaker, not against the best price available across other top UK betting sites.

To put it simply, BOG is a safety net for your own bet, not a way of finding the best price across every site. That said, you can rest assured that the bookie will not pay you at a worse price than the SP if that SP turns out to be bigger.

How Best Odds Guaranteed works (examples & infographics)

When you place a bet at an early price with a BOG bookmaker, the offer runs quietly in the background until the race is settled. You do not need to do anything extra. Once the result is confirmed and the SP is known, the bookie checks your taken price against the SP. You receive whichever is the bigger of the two.

Let’s look at two examples.

Example 1: the price drifts (you win more)

You place a £10 win bet on a horse at 5/1 at 8:30 am the morning of the race. When the race starts around noon, the SP has gone out to 7/1.

In short, you get an extra £20 for taking the odds being offered at the time of betting.

Example 2: the price shortens (you keep your price)

Now the other way round. Unibet had BOG on the 5:50 pm race at Yarmouth on 18 June 2026. At about 3:02 pm (just under three hours before the off) that same day, a horse called Celestra was priced at 8/13. Now, imagine you placed a £10 bet on Celestra to win at those odds.

Which UK bookmakers offer Best Odds Guaranteed?

According to the UK Gambling Commission’s registry data, there are currently 175 online bookmakers actively accepting bets in July 2026. I worked through around fifty of the better-known UK bookmakers, checking if BOG is available and the fine print of the offers. After that, I placed BOG bets and put them into practice.

I narrowed that list down to 22 best bookmakers for BOG, listed below in alphabetical order. I found William Hill, CopyBet, bet365, Sky Bet, Paddy Power, Coral, Ladbrokes, and BOYLE Sports to be the best.

BOG activates at 8 am, 9 am or 10 am on race day at most sites. The table below is a quick guide. The “maximum benefit” column is the most you can gain from BOG (I explain why that matters a bit further down).

Terms correct as of July 2026; always check the bookmaker’s current T&Cs before placing a bet. Bookmakers tested are listed alphabetically (not by rank).

What is the best UK bookmaker for BOG?

On the fine print alone, my favourite is CopyBet. It is the only one that switches BOG on from “final field declarations”, which can be the evening before the race, far earlier than everyone else’s 8 am or later.

It also has no cap on winnings, needs no opt-in, and covers multiples as well as singles. That mix of the earliest start, no limit, and no fuss is hard to beat on paper. No other betting site on our list is as friendly with its BOG policies.

How to know if a bookie’s BOG is actually good?

The honest answer is that “best” bookie for BOG depends on what you care about, so let me first set out what makes a BOG offer good. Four things matter:

1. An early start time. BOG only protects your price from the moment it switches on. The earlier, the more time the price has to grow in your favour while you are protected. So an 8 am start beats a 10 am start.
2. No cap on the bonus. Some bookies put a limit on how much extra BOG can earn you. A high limit (or no limit) is better, especially if you bet larger amounts.
3. No hoops to jump through. The best offers work automatically. The trickier ones make you opt in, join a club, or bet a certain amount each week first.
4. More bet types allowed. Some sites give you BOG on multiples too, not just single bets.

For most punters, Betfred is great. It is a big, trusted name with no cap, no opt-in and no membership card. Our Betfred review found that the platform is the rare one that gives you BOG in its 1,250+ high-street shops as well as online. One thing to note is that its Lucky 15, 31 and 63 bets do not count online.

If you want a safe all-rounder, bet365 is an obvious choice. Our bet365 review found no cap on BOG wagers and friendly start times of 8 am.

A quick warning on the other end. A few offers have small caps that you should know about before you bet big. 36Vegas and BetTOM cap the bonus at just £100 per bet, DragonBet at £250 per race, and BetGoodwin and Paddy Power at £1,000. For small stakes, these are fine, but for high rollers, they’ll hold you back.

BOG is more of a safety net, not a free bet pass. Most horses that win actually end up shorter at the off than they were in the morning, so the early price you take still matters a lot. Take good early prices first.

Which bets qualify for BOG?

Not every bet qualifies. Best odds guaranteed is typically available on win and each-way bets on UK and Irish horse racing across most UK bookmakers from the designated time on the day of the race.

Always check your bookmaker’s own T&Cs. Rules differ between operators, and they can be updated at any time.

Best Odds Guaranteed terms and conditions to watch

Operators with the best terms cover BOG from the earliest moment prices are put out. CopyBet is a good example. Other terms that determine whether your bet qualifies include:

Day-of-race start times

8 am is the standard time most BOG offers activate, including at bet365, Ladbrokes, Paddy Power, BOYLE Sports, and Unibet. At other bookies, BOG kicks in later at 9 am (Sky Bet, Grosvenor and BetMGM) or 10 am (BetGoodwin).

CopyBet is the exception. BOG is available from the point of final field declarations, which can be the evening before or even midnight on the day of the race.

Maximum benefit and payout cap

Several bookies cap the additional payout from BOG per day. For example, BOYLE Sports set the limit at £50,000. Some cap the payout benefit per bet, including BetGoodwin at £1,000. If you do not want to be bothered by these payout caps, consider bet365 and CopyBet, which have no restrictions on the benefits.

Market and region exclusions

BOG at most UK bookies applies only to UK and Irish racing. International racing, including Australia, the USA, Japan, Singapore, Hong Kong, and New Zealand, is excluded at bookmakers including bet365, William Hill, and Unibet.

Opt-in and qualification requirements

Some bookmakers require an active step from you before BOG applies. Paddy Power requires a one-time opt-in on the promotions page, after which it applies to all qualifying bets from 8 am the following day.

Coral and Ladbrokes also require a one-time opt-in. Our William Hill review found that it operates on an invitation basis, meaning the offer must be extended to you by the bookmaker. Sky Bet limits BOG entirely to Sky Bet Club members, which requires placing at least £30 in bets per week.

Rule 4 deductions

If a horse is withdrawn from a race after you have placed your bet, Rule 4 deductions reduce the odds across the board to reflect the smaller field. BOG still applies in most cases, but the comparison is made after the Rule 4 deduction has been applied to both your taken price and the SP.

Does BOG apply to football and other sports?

As of July 2026, no UK bookmaker offers best odds guaranteed on football leagues, cup competitions, or any other sport beyond racing. What is best odds guaranteed in horse racing is the full scope of where this offer operates.

Greyhound racing is the only extension, and not all bookmakers cover it. Those that do include Coral (UK and Irish greyhound races on race day), Ladbrokes (UK greyhound racing from 8 am), BOYLE Sports (UK and Irish greyhounds from 8 am, up to £50,000 online), BetGoodwin (UK and Irish greyhounds from 10 am).

How to know if your bet qualified for BOG

At most bookmakers, you can check your open bets after placing. Paddy Power, for example, will show a BOG indicator on eligible settled bets in your account history, whether your horse won or lost. At BOYLE Sports, the BOG icon appears on the meeting listing itself, so you can see before you place whether the offer is live for that race.

Is opting for Best Odds Guaranteed worth it?

If you’re regularly betting on horse racing and greyhounds, BOG is an obvious feature to have. It costs you nothing extra, and either pays you more or makes no difference.

Bookmakers reserve the right to remove BOG. Accounts that repeatedly target BOG markets with large stakes and exploit early prices may be restricted or lose access to the offer, but this does not typically apply to the vast majority of punters.
