To help readers get an idea of the best betting sites the UK offers, here are our top recommendations 🠋

Anyone looking around for new customer offers at betting sites, or even just offers for existing customers will know that it is easy to get buried under a ton of information.

So how do we break down the best betting sites? Our experts look at different criteria to judge betting sites by. Examining specific areas helps narrow down the best betting site offers. 
 
Here are some of the crucial areas that we put under the microscope to put together our rankings: 

➳ Welcome Offer 

The welcome offer is the first thing punters will experience when registering with a betting site. However, a welcome bonus doesn’t determine your overall betting experience. 

But we still judge sign-up offers by the bonus amount and something that gets overlooked, which is how complicated it is to claim it. 

➳ Fair Offers 

Betting offers come in different shapes and sizes. For example, some may offer a huge free betting bonus value but require a significant risk, making it less favourable.  
 
We look for what we feel are fair offers, which are essentially good value compared to risk. We also look at how the free bets from offers can be used and things like wagering requirements.   

➳ Seasonal Offers 

The sports betting scene changes throughout the year. First, there’s early action in the year with the likes of Six Nations Rugby, followed by the Cheltenham Festival, the knockout stages of the Champions League and conclusion of the Premier League and so on.  
 
We look at how well a bookie performs in promotions targeted at seasonal tournaments.  

➳ On-going Sports Offers 

Assessing the number of offers on popular sports is essential. The likes of horse racing and football are two big staples of UK betting site offers, and it’s where most customers are driven to.  
 
But not only do we look at the range of offers for specific sports, we also consider the number of free bets that can be applied to any sport. 

➳ Easy to Claim 

We support the best betting offers that are easy to claim. Having to go through a complicated process to redeem a bonus is not something a punter wants to suffer.  
 
We look at the terms and conditions of bookmaker offers to determine how much time you may need to invest to claim the offer. 

The best betting promotions come in different forms. Some, like Money Back Specials and Acca Bonuses, are more common than others. 
 
Here are some of the most common types of bet sites offered. 

↪ Money Back Betting Offers 

This is a popular form of betting bonus. After placing a qualifying stake on a select market, you are credited with a free bet bonus if some particular set of circumstances unfolds.  
 
An example is the Fitzdares 0-0 Bore Draw Insurance, where customers get a stake refund on pre-match Champions League bets if the game ends goalless. 
 
A Money Back Special is not as common among betting sites sign-up offers. But they are widespread among existing customer offers and can be integrated into your regular betting if they fit your strategy.  

↪ Acca Bonus Betting Promotions  

For players who enjoy a punt on an accumulator, finding bookmakers that offer a win bonus for successful acca will be a good fit. 
 
There are plenty of examples of Acca Bonuses available - 10Bet adds a cash bonus of up to 100% of your winnings up to a maximum of £5,000 for pre-match football accas of at least three legs. 
 
Acca Bonus promotions work on a sliding scale. The more legs that are in your successful accumulator bet, the bigger the percentage of payout is. 
 
While the top-end bonus of these promos look super-enticing, they will only apply to enormous accas. But still, even picking up a 10% bonus on a four-fold is a significant boost. 

↪ Acca Insurance Betting Promotions  

Another popular type of accumulator promotion is taking insurance on your accumulator bets. These, too, are very common, like the acca win bonuses. 
 
An Acca Insurance promotion covers a qualifying bet if it loses by one leg. Unfortunately, it can be a teeth-grinding experience losing a big acca because of one selection. 
 
Accumulator bets are a risky form of wagering. That's because all the individual legs have to win for the bet to be successful - the more legs, the taller the task.  
 
So snapping up acca insurance where you'll get a free bet or even cash back on a bet that loses by only one leg makes this a great promotion. 

↪ Loyalty Clubs 

A great way to stack up some free bets are through Loyalty Clubs. However, we will add the caveat that it is not worth overreaching your betting bankroll to try and claim a bonus through these types of programs. 
 
But if the bet requirements during a weekly promotional offer for a Loyalty Club is within your means, then rewards can be claimed. 
 
Many betting sites have some form of Rewards Club, including 10Bet, BetVictor and BetZone. 
 
The requirements will differ across them. But a minimum amount of stake will be required on settled bets within the qualifying period, usually a week. 

↪ Enhanced Odds 

While not a free bet offer, enhanced odds are some of the best bonus offers that can be snapped up, especially if they fall into place on a market you were already considering. 
 
Many bookmakers, including BetUK, Mr Play produce a lot of odds boost markets. They are for pre-selected market options, but because they don't come with extra T&Cs, they are a straightforward kind of bonus.  

↪ Free Bets Offers  

There are other ways to collect free bets. One of the popular ways is getting credited with a free bet by placing a bet on a qualifying market. 
 
These are generally launched on a specific event. So, for example, it could be placing a bet on the match winner of the UEFA Champions League final and getting a free in-play bet for that fixture. 
 
Among bookmakers that offer promotions like this are BetUK, who give a £3 free bet every week for at least £15 staked on horse racing.  
 
The best way to snatch up these kinds of one-time deals is to visit the 'promotions' pages regularly. 

A welcome bonus can be claimed only once after registering a new account with a bookmaker.  
 
You are not obligated to use a betting site's new customer betting offers, but they can provide a nice little betting boost to get started with. 
 
Welcome bonus offers are such a prominent feature of online sports betting. Visit any of the recommended bookmakers from this page and find one there. 
 
The most common format of a welcome bonus is a free bet. An example is the BoyleSports welcome offer, where you make a qualifying bet of £10 and get back £20 in free bets. 
 
Some welcome bonuses will credit free bets in one lump sum, but some may split the bonus total into smaller chunks. 
 
Another common form among Welcome Bonus offers is simply a matched deposit bonus. That's when a bookmaker will credit you with a free bet bonus linked to the value of your initial deposit without needing to make a qualifying bet. 

We have extensively researched the existing customer betting offers with the best betting sites. They are often worth digging deeper into because they provide long-term value for day-to-day betting. 
 
While betting sites with welcome bonus offers attract punters in through the door, promos for existing customers are great to fit into your regular betting. 
 
With that in mind, here are some of the best existing user betting offers and promotions that we have found. 

⤿ Horse Racing Money-Back 

There are good examples of horse racing bonuses where you can claim a lost stake refund. Boylesports have a money-back special if second to the SP FAV, while Coral will refund if a selection is beaten by a length or less. 10Bet have a similar offer if your horse loses by a neck or less. 

⤿ Cashback Bonuses 

Some bookmakers offer cashback rewards based on losses during a period. An example is the Fitzdares 10% back on losses in a promotional week played on Create-a-bet plays. In addition, Tebwin provides cashback offers on various sports like tennis, MMA and F1. 

⤿ Acca Free Bet Bonuses 

While punters can collect acca win bonuses and acca insurance offers, another acca offer is also available - claiming a free bet for placing a certain amount of acca stake.  

NetBet have a £5 free bet back for placing a £10 four-fold acca. In addition, BoyleSports have an acca loyalty club where you receive a free bet for placing regular accas. 

⤿ Best Odds Guaranteed 

This is a staple horse racing promotion and will be found on most betting sites for UK and Irish racing. Place a stake, and if your horse wins at a bigger SP than you backed your selection at, you get paid at the higher price. 

⤿ Fair Chance Offers 

A famous horse racing betting offer like BetVictor’s Run For Your Money lets punters receive a cash refund if the chance of their backed selection is scuppered right at the start of the race.  

Seasonal betting offers apply to major tournaments that swing into action throughout the calendar year.  
 
Think about the build-up to a FIFA World Cup or European Championships. You will see a lot of bookmakers push extra promotions to entice punters.  
 
These are big times for bookmakers as it is a great way to capture new registrations from event-specific promotions. 
 
Anytime a significant event such as the Grand National or Champions League is on, you can expect to see plenty of offers. For football tournaments, that could be a price boost on the outright winner or a money-back special on the Golden Boot market. 
 
Other major sporting events on the calendar, such as the Cheltenham Festival, Wimbledon Tennis and the PDC Darts World Championship, are also likely to have new promotions launched for them.  
 
Bookmakers will generally have extra place offers for the top horse racing events, best odds guaranteed, and free bet specials for feature races. So something like Royal Ascot is a great time to scout around for additional bookmaker bonuses. 

Anytime that you are doing online betting, you are going to come across betting bonuses. 
 
But they are not necessarily things that you have to use at all. So just because an offer exists doesn't mean you have to take part and use it.  
 
Perhaps one slight negative about looking for bookmaker promotion is that they can be tempting to play. Especially if you suddenly see a massive price boost for a particular match outcome or a free bet bonus. 
 
But the key thing to remember about any offer at the best bonus sites is that they should fit into your betting plans. It should not be the other way around because then you can end up betting on markets that you are unfamiliar with and even just taking offers that may not be a great deal, to begin with. 
 
New Customer offers are probably the type of bookmaker bonus that most players get pulled into. A problem with these are that players are lured into opening an account just because of the bonus, only to find issues like deposit restrictions and having to play through the free bet value to release the bonuses.  
 
You are under no obligation to use a Welcome Bonus. However, if such an offer requires a £10 minimum stake to trigger a free bet bonus, but you only play £1 horse racing accas, then you need to ask yourself if it is worth it. For some players, it may be, but it's all about your personal preference. 
 
The desire to open an account at a bookmaker should be based on the quality of the sportsbook, competitive odds, customer service and other features that you will rely on daily. 
 
There are so many terms and conditions that come attached to bookmaker promotions. We wouldn't expect anyone to plough through a long page of T&Cs for any offer.  
 
But listed alongside a deal will be key T&Cs, and these should be looked at. They will give a general picture of the steps you need to follow.  
 
Here are some things to watch out for when it comes to betting site offers: 

➪ Qualification Time 

Most welcome bonuses will have to be completed within a certain period from the opening of the account. That may be 30 days, for example, when any qualifying bet has to be settled.  

➪ Free Bet Expiration 

99% of the time, any free bets that are credited will come with an expiration time. So once they land in your account, you may only have a limited time to use them. The key T&Cs of a deal will inform you of how long it takes. 

➪ Market Restrictions 

Free bets may also come with market restrictions, meaning you can only play them on the next horse race or the First Goalscorer market. 

➪ Deposit Restrictions 

This is an area of betting site welcome offers that can catch punters out. Some bookmakers will exclude third-party payment methods like Skrill and PayPal from welcome bonus offers. So if you don't use a valid payment method, you'll miss out.
