Best Odds Guaranteed Bookies

Most punters know the fickle nature of sports odds and how they tend to change, often swaying away from your favour as time passes, but what if there was a way to circumvent this issue?

I’m talking about Best Odds Guaranteed promotions, or “BOGs”. These are typically available only on horse and greyhound races and allow you to get the most value from your wagers by guaranteeing you’ll win at the odds you’ve chosen or the listed starting price.

The reason why BOGs are huge in the UK horse racing industry is that non-adjusted odds tend to fluctuate wildly. They can skyrocket or plummet between the time they were listed and the moment the race starts, but they hardly float around the same margins.

You can find Best Odds Guaranteed deals at numerous UK-licensed bookies, but it wouldn’t hurt to know what sets these promos apart.

Many UK bookies offer Best Odds Guaranteed promotions, but some are swamped with complex limitations, while others start too late to be considered valuable. I’ve pinpointed 5 bookies with the most lucrative BOG deals, so if you’re interested in learning more, let’s dive into the reviews.

#1. betway

Betway Homepage

Betway has a solid racebook, but we are particularly fond of its British and Irish tracks as they are backed by the Best Odds Guaranteed (BOG) promotion every day from 09:00 a.m. onwards, which is close to the industry’s standard. Their Irish horse racing bets coverage, in particular, is excellent.

Tracks covered by this promotion include Newmarket, Newcastle, Bangor-on-Dee, Cartmel, Curragh, Doncaster, Yarmouth, Leicester, Hamilton, Nottingham, and several others.

One of the best features of Betway’s BOG offer is that you don’t have to opt-in to activate it. Essentially, you only need to place any horse-racing stake (excluding the “Luckies” 15, 31, or 63) in the morning before the race starts, and if you qualify for the Best Odds Guaranteed, you’ll see a small indicator on your slip.

Another reason why we love Betway’s horse racing in general is that most events are live-streamed in high quality. Moreover, this bookie imposes a generous daily benefit limit to its Best Odds Guaranteed promotion of £25,000.

Similarly to most UK bookmakers, Betway doesn’t allow you to mix the BOG deal with other odds-related promos, such as boosts or free bets.

Pros:

  • Most horse-race betting types are supported by the BOG deal
  • Hefty £25,000 daily benefit limit
  • Backs all available Irish and UK horse racing tracks
  • Doesn’t require you to opt-in to use

Cons:

  • BOG doesn’t apply to greyhound racing
Free Bet Up To £30 & 100 Free Spins
*New UK customers only. Min Stake: £5. Maximum Free Bet: £30. First bet on a Football or Horse Racing multiple with 3+ selections. Overall odds: 3.00 (2/1) or higher. Free Bets available upon settlement of the qualifying bet. 100 Free Spins on Gold Blitz (£0.10 per spin) credited on settlement of qualifying Acca bet. No wagering requirements on free spin winnings. Debit Card deposit only (exclusions apply). This offer is valid 7 days from the new account being registered. 18+ GambleAware.org. Bet the Responsible Way. Full terms apply.

#2. Betfred

Betfred Homepage

Betfred is another stellar choice for horse race punters looking for a sweet BOG deal. The site’s Best Odds Guaranteed promotion starts a bit earlier than Betway’s, at 08:00 a.m. sharp, which is undoubtedly a huge boost for them. Our favourite part is that it covers both UK & Irish racetracks and greyhounds.

There are a few unfortunate limitations that we’re not too fond of. For instance, highlighted (featured) races, tote, pari-mutuel, and lucky 15, 31, and 63 aren’t eligible bets for the Best Odds Guaranteed, which are popular in the horse racing betting market.

On the upside, the terms and conditions of this promotion impose no limits on how much cash can be won with BOG-adjusted prices. Betfred is among the few UK bookies with, or better said, “lacking” such rules, making them an ideal choice for prolific bettors. On the other hand, Betfred is also a solid bookmaker for low deposit bettors, as it accepts deposits of just £5, in contrast to others.

Pros:

  • No limit on earnings made through Best Odds Guaranteed
  • The promotion starts as early as 08:00 a.m.
  • Good for cash-strapped racing fans as it accepts £5 payments
  • BOG covers both horses and greyhounds

Cons:

  • Multiple bet types are excluded from Best Odds Guaranteed
  • Slightly narrower coverage of UK & Irish race tracks
Bet £10, Get £50 In Free Bets
New customers only. Register, deposit with Debit Card, and place first bet £10+ at Evens (2.0)+ on Sports within 7 days to get 3 x £10 in Sports Free Bets & 2 x £10 in Acca Free Bets within 10 hours of settlement. 7-day expiry. Eligibility exclusions & T&Cs Apply.

#3. BetVictor

BetVictor Homepage

BetVictor is our third choice, as this bookie offers a slightly stricter cap on daily BOG-adjusted winnings. Still, the site is comparable to Betfred and Betway in virtually all other fields, where you will get the best odds out there for UK and Irish horse racing.

Best Odds Guaranteed promotion at BetVictor can bring you a maximum amount of extra cash at £10,000 each day, which is 2.5x less than Betway’s offer. On the upside, most types of horse racing wagers are eligible for this promotion, excluding only live bets, ante-post stakes, and wagers placed with bonus bets.

Another similarity between BetVictor and Betway is that they both launch their respective BOG promos at 09:00 a.m.

Beyond Best Odds Guaranteed, BetVictor also offers another interesting “guarantee”. The “Run For Your Money” promotion is full cashback insurance for matches where your horse (or horses) refuses to run at the start.

Pros:

  • No opt-in is required to qualify for Best Odds Guaranteed
  • All standard wagers from £1 and higher are eligible
  • Decent £10,000 benefit limit
  • A solid “Run For Your Money” alternative to BOG

Cons:

  • Best Odds Guaranteed don’t cover greyhounds
Bet £10 Get £30
18+ New customers only. Opt in, deposit & bet £10+ on any football market (odds 2.00+) within 7 days of registration. No cash out. Get £30 in Free Bets + 1x100% Boost tokens (max £10 stakes) for selected football markets Free Bets expire in 7 days. T&Cs apply, see below. GambleAware.org | Please gamble responsibly

#4. Ladbrokes

Ladbrokes Homepage

Ladbrokes is one of the few UK bookies that cover both singles and multiples with a decent BOG promotion, putting them in a unique bracket. Every day from 08.00 a.m. until the race starts, you can place a real-cash wager on any UK and Irish horse race to qualify for the site’s Best Odds Guarantee of up to £2,500. This is among the superior best odds guaranteed offers due to the value and the fact you it covers multiples.

The early start and support for extensive market types are the main draws of this particular promotion. Beyond the BOG, we also love that Ladbrokes offers a 100% match on horse-racing bets of up to £5 once a day every week.

Pros:

  • No major limits besides the winning cap
  • No opt-in required
  • BOG promo starts early at 08:00 a.m.

Cons:

  • BOG-adjusted winnings limited to £2,500
  • Best Odds Guaranteed does not apply to greyhounds
Bet £5 & Get £30 in Free Bets
18+ New UK+IRE Customers only. Certain deposit methods & bet types excl. Min first £5 bet within 14 days of account reg at min odds 1/2 to get 4x £5 free bets. Free bets available to use on selected sportsbook markets only. Free bets valid for 7 days, stake not returned. Restrictions + T&Cs apply.

#5. bet365

Another recommendation for a UK Best Odds Guaranteed bookmaker is bet365. This is a long-running sports betting site founded in 2000 that generally offers competitive odds for horse racing events, so even without a BOG deal, you may want to give them a shot, as there odds across the board are some of the best around.

Whilst bet365 has been in the market for a long time, they are constantly innovating, making them one of the standout operators and one which many new betting sites look to replicate in terms of success.

Unlike our top four picks, the best odds guaranteed at bet365 has only a handful of significant rules. The promo starts at 8:00 a.m. each day of the week, and you can win up to £10,000 on price adjustments. While both of these rules may seem inferior to the terms presented by BetVictor or Betway, the true benefit of bet365 is that there are no other limitations.

Another standout factor of the Best Odds Guaranteed feature with bet365 is their Best Odds Guaranteed for greyhounds, which is something most of their competitors do not offer. Simply take a price on your chosen bet, and if the SP is bigger, bet365 will pay you out at the bigger odds.

Pros:

  • Higher payouts: if the SP (starting price) is higher than the odds you took, you’ll get the better price.
  • Applies to multiple bets: Best Odds Guaranteed covers various bet types, including singles and accumulators.
  • No extra steps: automatically applied, so there’s no need for users to manually opt-in.
  • Offers Best Odds Guaranteed for greyhounds

Cons:

  • Restrictiotns apply: certain bet types and events may not qualify for the offer.
  • Regional limitations: best Odds Guaranteed is not available in all locations.

#6. BoyleSports

The trend of Best Odds Guaranteed for horse racing continues with BoyleSports, who offer another chance to get the best odds around for all UK and Irish horse racing.  What’s impressive about the BoyleSports Best Odds Guarantee is their max daily winnings of £50,000 per player.

Better yet, similarly to some of the other Best Odds Guaranteed bookmakers mentioned above, BoyleSports try to get ahead of the competition with an 8:00 a.m. start for placing bets for the forthcoming day. However, only the outright winner on a singles bet is allowed for BoyleSports’ Best Odds Guaranteed.

Pros:

  • 8:00 a.m. start for BOG.
  • £50,000 max winnings per day for BOG.
  • No need to opt-in.

Cons:

  • Does not apply to ante-post tote/pools, place only, match bets, prices bets and specials.
  • Location restrictions.

Rating Bookies with Best Odds Guaranteed: Things We Looked For

Although they may appear similar, every Best Odds Guaranteed promotion is different. There are usually limitations to how much can be won, which bets can be placed, and which race tracks are covered. Additionally, the timing of BOG deals is extremely important, as the “real” best odds are typically listed early.

These are just some of the factors I used when evaluating Best Odds Guaranteed promotions at UK bookies, so let me elaborate on the process:

  • BOG Starting Time: Typically, most bookies launch their BOGs between 09:00 and 10:00 a.m., which leaves you with a solid 3-4 hours before the first UK races start. The best bookies offer their BOGs even earlier; for example, Betway’s Best Odds Guaranteed starts at 08:00 a.m.
  • Benefit Limit: Best Odds Guaranteed offers usually carry no rollover requirements and apply to all eligible bets, so to avoid losing too much money, most bookies will impose a benefit limit expressed in cash. Benefit limits may vary greatly from one site to another; for example, you can earn up to £2,500 via Ladbrokes’ BOG or up to £25,000 at Betway.
  • Sport Eligibility: Most bookies offer Best Odds Guaranteed deals on horse races, but some extend such offers to greyhound races as well.
  • Requirements & Significant Terms: Best Odds Guaranteed promos should be easy to use. In fact, you won’t have to do anything at all when you’re using such deals at top UK bookies, as your odds will automatically instantly be reconfigured as “Best Odds” if they’re eligible.

The Importance of Timing with BOG Promotions

One of the key “features” of every Best Odds Guaranteed deal is the moment it becomes active. I should also emphasize that BOG promos are usually available every day, so we’re mainly looking at the hour when they become active.

Simply put, horse race wagers are usually the best as soon as they’re listed. Various factors can make them better or worse over time, so you’re essentially racing to secure an advantageous position and the highest possible value for each eligible wager.

Restrictions & Rules

Bookies wouldn’t be making any money if anyone could use the best possible odds at any given time. This is the reason why every UK bookmaker will have a set of limitations and restrictions that define eligible bets, minimum qualifying wagers, maximum benefit limits, and other important factors. You will notice information in the fine print if best odds guaranteed applies to your offers.

I warmly recommend reading the full terms of each BOG deal you encounter to know what to expect. Even though these promos never have a “catch” that could adversely impact your betting experience, some Best Odds Guaranteed are more valuable than others.

Look out for Bookies with Best Odds in Multiple Bets

Part of your best odds guaranteed strategy may be to utilise full-cover bets such as Lucky 15 and Lucky 31. However, you will find these best are often excluded from the best odds guaranteed policy. Even though full-cover bets aren’t available, combining best odds guaranteed with multiple bets that bookies allow can see your potential earnings shoot up. If the starting price of any of your selections is greater than the price you originally took, a BOG policy means that your bet will be settled at the higher price. If you can combine some of these the returns could be very good.

If you enjoy placing multiples on horse racing, you should be aware that some bookies do not include BOG on some bets including perms and multiples, although they may say doubles and trebles are fine.

This means that you should definitely be picky when choosing your bookmaker, as you will notice the big difference best odds guaranteed can make on multiples.

Pros & Cons of Best Odds Guaranteed Bookmakers

Fundamentally, Best Odds Guaranteed promotions are inherently flawless – they are considerably different from regular sports bonuses since they don’t carry rollover requirements and or need a deposit to activate. However, it could be said that the incentive to place wagers knowing that your odds may get better than what you paid for could foster irresponsible betting, which is the only drawback BOG deals may have.

The advantages are quite obvious. You can get more value from a wager you’d place anyway, up to a certain limit. I’d also argue that the lack of any bonus requirements is a superb benefit in its own right.

How to Get Best Odds Guaranteed

In most cases, no specific actions are required to activate Best Odds Guaranteed promotions. Bookies launch these promos every day at a predetermined time and have certain conditions that need to be followed, and as soon as you meet these, placing a wager is all you need to do to participate in a BOG promotion.

Although no opt-in is needed for activating Bets Odds Guaranteed on your bets at the online bookies I recommend, keep in mind that some bookmakers may have different rules.

Managing Your Bankroll Effectively

As I mentioned, BOG deals may indirectly incentivize irresponsible gambling. You may feel like you’re spending less and think that using that extra cash for other bets is a smart choice, or you may think that it would be a waste not to reap every good opportunity that comes your way.

In truth, Bets Odds Guaranteed bonuses are only good if the punter is well-disciplined.

These deals are available every day, so unless there’s a major tournament, you won’t miss anything by spreading out your wagers to fit your bankroll and realistic financial capabilities.

Fortunately, all bookies I recommended actively support safer gambling, allowing you to use a range of tools to limit your spending or keep you away from gambling altogether at the chosen venue.
