Reviews of the Best Best Odds Guaranteed Bookmakers:

1. bet365

Pros

• There are a tonne of betting markets available for participants
• They have a great reputation in the gambling sector
• They’re widely recognised all over the world rather than just in one place

Cons

• Sadly, they do restrict accounts for individuals that win excessively
• They are subject to certain extremely tight national and regional limitations

Due to the many promotions and offers it provides for the sport, Bet 365 is a significant bookmaker on our list of best odds guaranteed bookmakers. They offer a wide range of sports and events as part of their inventory and they provide lots of markets within each sport too. Due to their excellent reputation, they are highly recognised across the world, however if you reside in an unauthorised zone, they do have some tight geographic limits. Additionally, you run the danger of having your account closed if you win too frequently.

2. BetTom

Pros

• Up to £25 as a free bet based on your first day's losses

• Best Odds Guaranteed on all UK and Irish races plus free streaming

• Make secure bank payments using the BetTom app

• Double result payout: first past the post and amended result

Cons

• The main payment methods are Visa and Mastercard

BetTom is regarded as one of the most superior horse racing betting bookies, and it's hard to argue otherwise.

New BetTom customers get up to £25 as a free sports bet, which is dependent on the losses incurred on your first day by 23:59. To qualify, you must place at least three bets worth £10 or more each with minimum odds of 2.00. Half of your losses will be returned to you as a free bet within 24 hours.

BetTom has best odds guaranteed on all races in the UK and Ireland, which includes singles and multiple bets. The promotion is applied only after 10 am on the day of the races and is capped at a maximum of £100. Unfortunately, international races, ante-post bets, and special markets are not considered for the best odds guaranteed promo. Even though BetTom has a diverse range of meets in 16 different countries, UK punters are naturally more inclined to bet on national races which makes BOG ideal for BetTom customers. There are races in Wolverhampton, Newcastle, and many more that can be streamed from your device at the press of a button. A similar bonus is the Double Result Payout, where bets are paid out on both the horse that passes the post first and the official result, if the result is amended.

It's worthwhile noting that BOG is also offered on greyhound racing with the same terms and conditions as horse racing.

3. William Hill

Pros

• They have a huge selection of games and events
• They allow early cash out along with other reload promotions
• They have a great live stream feature on their desktop site

Cons

• Their bonus for new users is not too generous
• They don’t offer live streaming on their phone app at all
• The don’t have the most competitive odds

William Hill is a regular on the best odds betting list due to providing recurring promotions and offers for popular races to their repeat customers. They have a fantastic reputation within the UK & Ireland and are one of the nation’s favourite bookmakers overall. Unfortunately, they don’t have amazing odds for their sports or a generous welcome offer but they do make up for that in other ways and with special features. They always have a huge selection of betting markets and events to choose from and for those fans of racing you can certainly take advantage of their best odds guaranteed offers. Another one of their popular features is the early cash out offer which allows players to withdraw money out early before the event has finished.

4. LiveScore Bet

Pros

• Bet £10 and get £30 in free bets

• Best Odds Guaranteed on all UK and Irish horse racing

• Non-runner money back on famous festivals

• Extra places every day on selected races

Cons

• Acca offer free bet cannot be used on forecast bets, tricast bets, or each-way bets

LiveScore Bet has numerous horse race betting promotions from best odds guaranteed to money back as a free bet. New customers can benefit from the welcome bonus, which is only available in the UK. Place a bet of at least £10 on any sport including horse racing, and you will get £30 worth of free bets. This is rewarded as two £10 free bets and two £5 bet builder free bets.

The Best Odds Guaranteed promotion is available on LiveScore Bet, but the terms and conditions are important to read. You must stake at least £25 in a seven-day rolling period for the offer to apply and ante-post, international racing, and cashed-out bets don't apply. Bets placed with free bet tokens also don't apply. The Best Odds Guaranteed promotion is only for win-only and each-way betting markets and applies after 10 am every day on UK and Irish races. The maximum increase in returns is capped at £50,000 which is standard. So, what does this all mean? If the price that is available for the horse at the start of the race is higher than the odds you placed, you will be paid out the starting price. If not, you will be paid out based on the original odds. Whichever price is higher will be cashed out, as long as the bet is qualifying.

Other horse race betting promotions at LiveScore bet include money back as a free bet if your horse finishes second, and extra places every day.

5. HollywoodBets

Pros

• Free bet up to £30 on your first losing acca

• Best odds guaranteed on all British and Irish racing

• Win cash and betting vouchers on South African racing

• Profit boosts on winning horse racing accas up to 70%

• Bet with Visa, MasterCard, Apple Pay, Google Pay, Skrill, Neteller, Rapid Transfer and Neosurf

Cons

• Acca insurance is only available on football

HollywoodBets is a grandiose betting app that is criminally underrated when it comes to horse racing promotions. New customers who register and deposit at least £10 get up to £30 in free bets on their first accumulator bet loss that has more than three legs with odds of 4/1 or greater. The acca bet must be settled within the first week of signing up.

Best Odds Guaranteed means that if the starting price of the horse you bet on is higher than the odds at the time of the bet, you will be paid out whichever is greater. The Best Odds Guaranteed at HollywoodBets is better than other BOG offered by betting sites for countless reasons. Firstly, it is applied to bets placed after 8 am on the day of the race, when other bookies usually apply it after 10 am. Secondly, it is available on British, Irish, and South African horse races and luckily HollywoodBets has extensive coverage of the races. Best Odds Guaranteed isn't offered on ante-post bets, tote bets, and cashed out bets, however this is to be expected.

HollywoodBets aims to be interactive and this is proven by their missions, like depositing a certain amount per day or per month and getting free bets back to use on the horses. In addition there are acca bonus profit boosts on horse racing winning accas up to 70%.

6. BestOdds.com

Pros

• Gain five £5 free bets by placing your first £20 bet

• Best Odds Guaranteed on all ITV races

• Extra places on races like Newcastle

• Watch games via the free live stream on the BestOdds app

Cons

• Payment methods are Visa and Apple Pay

BestOdds was founded in 2021 in Ireland and has consistently delivered competitive odds and horse racing promotions since its establishment. Races are divided into UK & Ireland, International and Future races.

First things first, new UK customers should make use of the welcome bonus. Bet £20 at minimum odds of Evens (2.00) and you will get five £5 free bets that can be used on any sport including horse racing. The first free bet is credited as soon as your qualifying bet settles, and the remaining free bets are credited every 24 hours. Use the code 20x5fb to claim the welcome bonus.

As the BestOdds platform is chaotic, you may not find the Best Odds Guaranteed promotion despite the fact that it exists. It is valid from 10.30 am on the day of the race and applies to singles and multiples bets on all ITV races. The races this includes are specified on the website once you click the offer. Live streaming is available mainly on national races, and rarely on international meets. Log in to watch them live with clear quality and audio.

Extra Places is an extra horse race betting promotion at BestOdds that is handy when you narrowly miss out. The place part of an each-way bet means that you will be paid out if your horse places in the top runners, usually the top three. With this bonus an extra place is added so your bet will be paid out if your horse places in the top four.

7. Vickers

Pros

• Bet £10 and get £20

• Best Odds Guaranteed every day from 10 am

• Money Back Saturday Racing specials

• Bet Vickers mobile app is available for download on iOS and Android

Cons

• Website is lacklustre and cluttered

Vickers Bet was founded by a jockey and therefore it makes sense that horse race betting is exceptional. From best odds guaranteed to money back specials, there isn't much more you can ask for.

Vickers Bet didn't have a welcome bonus for a long time, but recently they have launched a new customer offer. When you place a bet with a minimum of £10 on the sportsbook you will get £20 in free bets to spend on any sport such as horse racing.

Best Odds Guaranteed is applied to selected UK and Irish games from 10 am the morning of the race until the end of the day. Winnings are capped at £1,000 each day. On the Vickers Bet website you can filter races to include only UK and Ireland, which makes it easier to see which races have Best Odds Guaranteed applied. Only races today and tomorrow can be viewed, with no option for futures betting. Overall, there isn't a wide variety of races but the most important events are listed.

Money back specials are regularly available at Vickers Bet, with a minimum deposit as low as £1 on the weekends. Installing the app is encouraged because you can set reminders for races that have best odds guaranteed ensuring that you don't forget to place bets, and also get your stake back on losing bets whenever applicable. Every day there are also extra places on highlighted meets, excluding ante-post bets; between three and five places will be paid out depending on the number of runners.

8. Ladbrokes

Pros

• Get £30 in free bets by placing a £5 sports bet

• Best Odds Guaranteed on UK and Irish racing

• Get your stake back if your horse is declared a non-runner on selected races

• Horse racing bet builder with multiple markets

• Win tickets for The Ladbrokes Trophy at Kempton

Cons

• Mobile app is slow and occasionally glitches

Ladbrokes is a reputable betting site that offers a whole host of sports like horse racing. The esteemed bookmaker is the five-year sponsor of the Kempton Park Racecourse and shows just how involved it is in the racing industry. As a Ladbrokes customer, you are in with the chance of winning tickets to watch the festival live as well as at Cheltenham.

New customers at Ladbrokes who bet £5 within two weeks of registration will get four £5 free bets and two £5 bet builder football market free bets. To improve, Ladbrokes could curate a welcome offer specifically for horse racing, as some UK betting sites have started to develop.

Best Odds Guaranteed is applied to all UK and Irish horse races including singles, multiples, early prices, and board prices. When the starting price returns are greater, you are promised to be paid out the higher earnings. The markets on which Best Odds Guaranteed is applicable are only win-only and each-way bets. The offer is capped at £10,000 each day and doesn't include ante-post, tote, place only, and top finish bets. To claim it there is no minimum spend; you just have to place a bet from 8 am on the day of the race. You cannot cash the bet out.

Ladbrokes also shows other promos like daily boosts, free spins to redeem cash bonuses or Ladbucks, extra place offers, and lastly non-runner no bet bonuses.

9. Puntit

Pros

• Puntit welcome offer worth £10 in free bets

• Best odds guaranteed on UK and Irish horse racing from early morning

• Jump Start cash refund if your horse fails to come out

• Lucky Dip horse racing singles markets

Cons

• Few racing bonuses on the sports home page

Best odds guaranteed is just one of the many horse racing promos that Puntit offers. To get acquainted, Puntit offers new UK customers £10 in free sports bets when you deposit £20 and place a bet on any sports market with odds of 1/1 or greater. Although this is one of the more miserly welcome bonuses, you can still use it to experiment with horse race betting.

The Best Odds Guaranteed bonus at Puntit can be found on the sports offers page which is somewhat hidden. From 9 am, Puntit will pay out the highest price out of the SP and the original odds. Hence, you can take the Early Price or the Board Price at any UK or Irish race. There is no wagering requirement and the maximum real cash benefit is £10,000 per day. Qualifying bets cannot be cashed out or subject to a bonus. In the future, Puntit could refine its platform by applying Best Odds Guaranteed on Lucky Dip betting, as at the moment the promotion is not available. Instead, you choose a stake, spin the wheel, and receive a random selection where the odds are final.

Below Best Odds Guaranteed you will see the Jump Start bonus, which gives you your refund back if your horse loses before the race even begins. An instance where this would be applicable is if the horse refuses to come out from its starting position, so Puntit would return your stake.

10. CopyBet

Pros

• Official partner of the QPR football team

• Double your stake by betting £20 and getting £20 back in free bets

• Best Odds Guaranteed for all users every day

• Profits boosts on any single bet by up to 15% every day

• Platform is sleek and contemporary

Cons

New users in the UK who bet £20 on a single or acca bet with odds of 1.9 or greater will get £20 from Copybet as a free sports bet to use on any sport.

When you see a BOG icon next to a meet, this indicates that the race qualifies for the Best Odds Guaranteed promo. You can view races weeks in advance and additionally browse through future races. This means that you will be paid out the starting price if it is higher than the early price or the show price. You don't need to turn this feature on or use any cryptic promo codes, BOG applies itself to all singles, accumulators, and other multiples that are on UK or Irish horse races. In total BOG includes almost 90 racecourses, 60 of which are in the UK. Win-only and each-way betting are the only markets that are eligible.

Other racecourses that BOG isn't applied to are South African, Japanese, and American. In spite of this, the odds are still competitive and there are plenty of amazing betting markets. Live streaming isn't offered by Copybet right now, but we will keep our eyes peeled for any new advancements.
