What Is a Good Sports Betting Bonus?

There is no one answer to this question as it depends on what you are looking for from a sports bonus. In saying that, when it comes to sports betting, value is the king. Therefore, good sports betting bonuses could include free bets, risk-free bets with a long, or no expiry date. Restrictions such as being event-specific can also make an impact, as well as how high the wagering requirements are.

Wagering requirements, sometimes known as turnover can make or break a good betting bonus. If you think an offer sounds too good to be true, then we recommend you read the terms of the offer. These will vary massively from bookie to bookie. We haven’t included any bonuses on this page that have crazy turnover requirements of x50 upwards – but they do exist! It goes without saying but the lower the wagering requirement, the more realistic it is that you will meet them and be able to withdraw your winnings.

Free bets are popular means of sports betting bonuses and can be great. They are often used by bookies as welcome promotions but they are just as likely to be used as a means of a loyalty reward. The pitfalls to look out for are short expiration dates, huge turnover requirements, and even minimum odds or stakes.

We would suggest that a good free bet offer would be available for a minimum of seven days and with a minimum odds restriction of around 1/2 (1.5). Anything below those odds would be hard to back considering a free bet will be for a set amount and the stake is not returned with your winnings, so don’t let the minimum odds put you off.

Different Types of Online Sports Betting Bonuses

Welcome Bonuses are the first thing we think of when we consider sports betting bonuses, but there’s more to bookies than those. Furthermore, new customer offers are very unlikely to be exactly the same. They can use the same mechanics but the structure or terms can vary greatly. There isn’t too much variation on what type of bonus is on offer but the great thing about that is that you know what you’re getting.

The most common types of sports bonuses are these:

100% Deposit Boost

Normally this will be a new customer offer, you’ll likely be offered a 100% deposit boost on your first deposit. This is sometimes referred to as a deposit matched bonus. Effectively this will double your first deposit. It is more common for casino players with many sports betting bonuses veering towards the side of free bets.

This is because these promotions tend to come with high wagering requirements – more suited to casinos. This isn’t to say there is no value in these as you have twice as much to play with – just check terms carefully to avoid disappointment.

Bet and Get – Free Bet(s)

This type of offer has become the bread and butter of sports betting bonuses. You’ll notice that a high percentage of our recommended bookmakers offer a bet and get style welcome offer, based on your first bet. This is where you’ll be asked to place a bet in order to get the next bet. For example, 888Sport; register, enter the code 30f, place a qualifying bet and you’ll get 3 x £10 free bets once it’s settled.

It’s a simple process which is why it’s so appealing to punters. On top of that, there are rarely wagering requirements so what you win – you keep.


Profit Boost

Not as common as other bonuses, but its certainly interesting! LeoVegas gives its new players the chance to get up to £100 extra on their first bet with its welcome offer. It’s referred to 100% profit boost and doubles your first bet winnings (if any). It should be noted that it applies to pre-match bets placed on your mobile-only. None of our other bookmakers currently offers this, find out more about LeoVegas with our review.

Risk-Free Bet

No risk but possible reward? Yes, please! New players can be offered a Risk-Free Bet and it is exactly what it sounds like. Place your first bet, and if it doesn’t win – get your money back. This is refunded in cash with many bookies including SportNation, meaning you can withdraw your money or try again for free.

No Deposit Bonuses

From a punter's point of view, these are obviously great. You don’t have to part with any of your hard-earned cash to take advantage, hence the name no-deposit. Sadly, however, these have all but disappeared as sports betting bonuses. You will still find them as free spins with certain online casinos, but are unlikely to discover and that focus on sports.

Sports Betting Bonus – Mobile Specific

Similar to no deposit bonuses, mobile-only bonuses are on the decline. They were more popular when betting apps were just launched but can still sometimes be used to encourage players to check out mobile betting sites. Especially if the bookmaker is particularly proud of a new feature. Often they hold value, so if you do see one pop-up, it’s worth giving it the once over. Find out more about our recommended best mobile betting apps here.

Bet Clubs

These are a cool way for existing customers to benefit from rewards. Although several of the big bookmakers have rebranded their ‘bet clubs’ they still exist. If we look at the Paddy Power Rewards club, it’ not includes its previous bet club. If you place five qualifying bets in a seven day period you’ll get a £10 free bet. You can do this as many weeks as you want so it does pay to stick with a bookie in these situations.

Loyalty Free Bets

You may be thinking that we’ve just covered those. Well, we have and we haven’t. Bet Clubs very clearly show you what reward you will receive for your actions, where loyalty bonuses are more discreet. Loyal customers can receive bonuses out of the blue for specific events, or even have some cash dropped in their account. Unlike Bet Club free bets, they are not guaranteed.

Some sportsbooks also offer VIP clubs that award special bonuses from time to time. It’s certainly worth having a look around at which bookies do offer these. And don’t forget, you can always contact the bookie's customer support channels to request bonuses. Don’t be shy.

Competition giveaways

Ok, so technically not a bonus – but these can be very cool. Many bookmakers will give the chance to grab some awesome experience prizes. You can enter competitions in a number of ways but it could be based on a bet. Prizes include trips to stadiums and events such as the Euro’s, Champions League and Premier League. Keep your eyes peeled for these and remember, you’ve got to be in it to win it.

Best Online Sports Betting Bonus – Football Promotions

The most popular sport around the globe is football, because of this, you’ll never be short of finding a sports betting bonus for it. Whilst the above promotions include football, there are also bonuses targeted mainly at football. This is really cool because they will include things like odds boost and accumulator insurances which can offer real value.

Furthermore, these bonuses are likely to be available daily, or at least for every major football game. On top of that, they are open to both new and existing customers, meaning no matter when you joined, you can take advantage. Check out the main types of offers here:

Enhanced odds
Accumulator Boosts
Accumulator Insurance
0-0 bore money back
Live betting enhanced odds

There are many more variations that you could be offered, and they are for the most self-explanatory. We’ll cover the accumulator boosts and insurance to show how they vary.

Accumulator Insurance

This is offered by the big bookmakers such as bet365 and William Hill. They provide you with your stake back if one leg of your acca bet lets you down. We all know how easy that is to happen!

Accumulator Boost

Unibet offer players an accumulator boost, or a multi-boost. This is different from the insurance as it requires your acca to win. There are other sites that offer a similar boost, but Unibet’s variation of it is very simple and you can get up to £1,000 extra on your winnings. It basically increases your profit by either 5%, 10% or 15% depending on how many legs are in your acca:

Legs in accumulator Profit Boost %
3 5%
4 10%
5+ 15%

Worth noting that it will not apply to any accumulator that you cash-out early on.

Unibet-multi-boostSports Betting Bonuses – Pros and Cons

As we mentioned at the start, not all bonuses will suit all player types. So it’s important to check out the terms and conditions of each bookie you sign-up for to avoid feeling disappointed later down the line. We’ve walked you through what sort of sport betting bonuses you can expect as both a new and existing customer, here’s a recap of the pros and cons of claiming those offers.


  • Risk-free bets give punters the chance to place a bet without any of the risks. If your first bet loses, the stake is returned in cash meaning you can withdraw if you want to giving you nothing to lose.
  • Welcome bonuses, in particular, can be very attractive, ensuring you get value from the start
  • Ongoing loyalty bonuses give you rewards
  • Using a bonus or free bet is a good way to turn a profit with less of the risk


  • Terms and conditions can be complicated and make it difficult to complete a bonus
  • Minimum odds can sometimes restrict where you want to bet
  • Wagering requirements can cause a bit of a headache as you have to turn your winnings into cash
  • Expiry dates mean you have to place bets in a certain time period
  • Some payment methods are not eligible for bonuses

Best Sports Betting Bonuses – Grab the Value

In conclusion, sports betting bonuses can be great little extras but shouldn’t be relied on when betting online. Enhanced odds and free bet offers are your best bet when you’ve already claimed a welcome bonus of a certain bookmaker, as they offer the most value. Enhanced odds markets may have a lower maximum stake than other markets, but they are still worth a punt if you fancy the bet of course.

By far the most value lies in welcome offers. Therefore, if you haven’t already it may be worth signing up with a few of our recommended online bookmakers. You’ll then be able to take advantage of all of their welcome bonuses.

Whatever you bet on next, be sure to shop around for a great sports betting offer. With so many around, especially on football – you’re bound to find what you’re looking for. Good luck!

Best Sports Betting Bonuses – Frequently Asked Questions

Q: Can I withdraw winnings from a Free Bet?

A: In terms of sports betting bonuses, free bets are one of the most common. The winnings will be added to your account, but the stake will not be returned. This is how a free bet will work with most, if not all bookmakers.

You should also check the terms of your bookmaker regarding any wagering requirements that may apply to your winnings. You may need to play through those a few more times in order to be able to withdraw, but it varies from bookmaker to bookmaker.

Q: What is a Risk-Free Bet?

A: This is a variation of a free bet. You will place a bet as normal with your own cash, and it loses you will get your stake refunded. If your bet wins, then you win and the Risk-Free Bet will have been used. The refund for a Risk-Free Bet is often in cash, but we recommend you check the terms of the bookmaker.

Q: What UK bookie has the best sports betting bonus for new players?

A: There are tons of exciting welcome offers to sign-up for, and the vast majority will give you a great deal. We’re a football focussed site, so we at PremierLeaguePress like offers which link to football.

Paddy Power gives you the chance of placing a £20 Risk-Free Bet, while at bet365 you can get up to £100 in bet credits. It really depends on you. But we would highly recommend either of these.
