What is a betting bonus?

A betting bonus is not just one defined thing. They appear in different shapes and sizes. From betting signup offers through to enhanced odds to daily bonuses on horse racing, there are different types of betting bonuses to explore.

It is important to realise that any betting bonus will have some terms and conditions attached to it. You have to ensure that all terms and conditions are fully read and understood before jumping into something. Sure it’s not the most exciting thing to do, but it will help you not miss an opportunity.

Generally, a betting bonus will be something that the bookmaker offers through a welcome bonus, which will involve some kind of free bet bonus heading back to your account. Any such free bets will then have their own sets of terms and conditions, such as what markets they can be played on.

So let’s take a look at a few different types of betting bonuses below and don’t forget to check out or list of most highly recommended bookies on our Bookmakers Page

Types of Betting Bonuses

Welcome bonuses are the most recognisable of all of the types of betting bonuses. These are the offers that you will see emblazoned across splash scenes when you visit a bookmaker. A form of betting offers for new customers is a matched deposit bonus. This is where, upon depositing an initial qualifying bet and (generally) settling your first bet, a bookmaker will give you bet bonus cash matching your initial deposit, up to a maximum limit.

Enhanced Odds

You will also be able to find special enhanced odds offers as welcome bonuses and ones for existing players too. Say for example in the FA Cup Final, a bookmaker offers a 50/1 enhanced odds sign up offer on Harry Kane scoring first. There may be a £1 maximum stake on that offer only, but if the bet wins then you would bank the bonus cash rewards.

This is a big lure for players who see inflated odds and want a piece of that action. Because offers like this always have a low stake, then they have extra appeal. As far as welcome bonuses go they aren’t a bad deal really because of low risk, but normally the rewards will be offered as free bet bonuses and not real cash, although exceptions do exist.

Money-Back Specials

There are variations of money-back specials available to all players, not just new customers. But they are a popular format for new customer sign up offers. With Money Back Special offers this means that a lost stake will be returned in the outcome of a specific bet not ending in your favour.

Say a losing first goalscorer bet could be returned, if the bet gets ruined within the first ten minutes. Or perhaps a match-winner has been selected and the team opens the scoring but fails to win the match, that could trigger the betting bonus.

What to look for when choosing a sign up betting offer

Let’s focus now solely on the sign up betting offer deals that are so common. Most bookmakers will have them and they will probably all vary slightly in their own unique way. So what exactly should you be looking for in a signup betting offer?

It is worth remembering that any bonus offer that you do end up engaging in, doesn’t determine the overall service of a bookmaker. A generous welcome bonus offer isn’t going to do you much good if the odds in the sportsbook doesn’t offering value. So basically pick the right bookmaker first and then take advantage of a betting offers sign up deal that they have.

Let’s explore some of the main things to look for in betting welcome offers.

Initial stake value

The bookmakers are trying to offer you a betting bonus so that you sign up with them. So there’s generally nothing little risk for the punter in these deals. You are probably going to have to come up with a stake first of all to trigger a welcome bonus.

Here’s what to consider. You are being offered a risk-free bet of £25 to start with if your first bet loses. If you play the bet, it loses and then your stake gets refunded as bet bonus cash, that’s not the same as real cash.

There will be terms and conditions applied to the free bet bonus returned, like a time limit to use it before it expires. So always read the terms and conditions on betting sites with offers and take a moment to assess whether it is of any real value for you.

First bet

Most welcome bonus offers at bookmakers will require the special offer to be activated with the first bet on the account. So make sure that you have hit all of the requirements of the offer, such as minimum deposit, minimum odds, minimum/maximum stake and even check if there is a further step of opting-in into a promotion that needs to be done. Also, check for any bookmaker bonus code that needs to be initiated during sign up.

Minimum deposits

You will have to fund your new account first of course. Most bookmakers will require a minimum of a £10 deposit on an account before playing. Check and make sure than any minimum deposits are performed first.

Deposit methods

Note that not all deposit methods will allow you to qualify for a bookmaker welcome bonus. The most common to not be accepted for bonuses are Neteller, Skrill and Paypal deposits. Check on the website first because the wrong deposit method could mean that you miss on the welcome bonus offer. Credit Card payments and deposits through e-wallets which were funded by credit cards, were banned by the UK Gambling Commission in April 2020.

Time limits

One final thing to remember about any betting sign up offers will have time limits on them. These time limits will be on things like having 7 days from opening the account to make your first deposit. You may have to settle a bet that applies to the welcome bonus offer to complete the deal. Any free bet bonuses that come back to your account after a welcome bonus has been completed will also only be valid for a set period.

Next major sports events

When major sports events come around, such as the Cheltenham Gold Cup, for example, that is when you will see an abundance of extra bookmaker offers come up. The big events like that are going to be a big time for the operators to try and capture extra business, so it’s generally a good time to search for a signup offer.

We have highlighted some of the top events around which are good times to explore bookmaker offers. One of the top ones is going to be the Grand National whether or not you are a big racing fan. It’s one of the biggest days of betting in the calendar year. Other big events include the summer treat of Grand Slam tennis from Wimbledon and the British Grand Prix.

There is also the  Darts World Championships, the FA Cup Final, the UEFA Champions League Final and other top events like the Cheltenham Gold Cup, the Snooker World Championships and Snooker Masters. These are all great times to look for betting sign up offers. You can always look around ahead of big tournaments, like the UEFA European Championships and the FIFA World Cup.

Best betting offers for existing customers

There is also a big market for betting offers for existing customers. Once a bookmaker has a customer signed up they are going to want to keep them around, of course. That is why you will find a great deal of betting offers at online bookmakers beyond that initial welcome bonus.

These are generally a lot more valuable to players as well. Just to explain, imagine that you frequently play accumulators. If you have a bookmaker which offers accumulator insurance, where the lost stake is refunded if just one leg of the bet loses, then over time that could give you a lot more value than picking up a £10 free bet as a welcome bonus.

So it is always worth taking some time to look around and explore just exactly what is on offer inside a bookmaker’s website. Of course, offers will change, offers will come and go but some great ones stick around and here we take a look at some.

Acca Insurance

This is a popular form of betting bonus, for those who like a little bit of a flutter on an acca. Acca insurance is generally when a bookmaker offers the bonus of a return of stake if an accumulator loses by just the one leg. This is a very common offer that punters can take advantage of and most bookmakers will have some kind of version of it.

Free Bet Clubs

Several operators also offer a free bet club. This isn’t going to be found in the betting offers sign up deals though. Free bet clubs can be thought of a loyalty club really, where a bookmaker will issue a free bet once a week if you have bet to a stake minimum amount during the week. Just for an example, you may get a £5 free bet on a Sunday for having placed £25 worth of qualifying stakes during the week like at Coral’s Bet & Get Club.

Horse Racing bonuses

It is not uncommon at all to find things like Best Odds Guaranteed, Extra Places and Non-Runner No Bet options for horse racing. With horse racing being such a major part of the UK sporting scene then bookmakers compete for a lot of action in this area. Getting the Best Odds Guaranteed (where you get paid at the bigger price if horse’s starting price is larger than an early board price that you took) can add a lot of value.

Acca Percentage Bonuses

Another popular way that bookmakers deliver a little extra to successful bets is through Acca percentage bonuses. A lot of top operators will offer this. If you manage to land a successful acca, which in and of itself is a pretty tough thing to do, then you will claim a percentage bonus on top of your winnings. How much that will be will be will depend on the size of the accumulator. You may get a 5% win bonus for example on a successful 4-fold, but then a 15% bonus say on a successful 10-fold. It will vary from bookmaker to bookmaker so check out the terms.

Enhanced Odds

Bookmakers offer enhanced odds options beyond welcome bonuses. It’s not that uncommon for bookmakers to give price boosts on select markets. Again this is another variable between different operators. Some, notably like BetVictor do tend to throw out a lot more enhanced odds offers than other bookies do.

The good thing about enhanced odds that are out there for existing customers is that they are just going to be a straight boost of cash on top of your regular odds. It’s not going to be a complicated affair of free bet bonuses. Bookmakers will just raise the general market price a bit of a selection to back.

A variation of this will be bet boosts. Sometimes bookmakers give out a bet boost to customers. These then can be applied to a bet of your choice. One of the bookmakers who frequently do this is William Hill, where they supply good bet boost options for their customers. The boosts will likely have terms and conditions, such as minimum stake.

Money-Back Specials

Usually, this will crop up when there is a big sporting event. A Money Back Special is a type of bet where the bookie offers to eliminate some risk on a given outcome. It may be that your first qualifying stake on an account gets refunded if it is lost. The operator returns the lost stake as cash or bet bonuses to your account. As mentioned above this is the most popular form of welcome bonuses for online betting.

UK Bookmakers without Betting Bonus

There are also some bookmakers, that don’t offer any welcome bonus at the moment. Reasons for this decision are different but don’t affect the bookmaker itself.

Best betting sites in the UK

So the big question is which are the best betting sites in the UK? There are so many options to choose from, and that can lead to confusion. But that’s what we are here for, to make the choice just that little bit easier.

Here we take a look at the top bookmakers which we have studied. Again there have been many different criteria applied in our search, even down to things like security and account management. Time and time again in the many different areas in which we looked, the same names kept coming up.


The bookmaker just continues to grow and grow in stature in our opinion. One of the immediately notable things about Bet365 is the vastness of their sportsbook and the value of their odds within in. They are consistently competitive and at the better end of the scale for market value when doing odds comparisons.

That’s not just on the top markets either, it is on the lesser backed ones as well. Bet365 are not a site which delivers a tremendous amount of big betting offers. But they do have some in a place like their Best Odds Guaranteed, Each-Way First Goalscorer markets and 0-0 Bore Draw insurance.

It is the odds and market variety that makes bet365 stand out, which is such a good thing. They also deliver a superb live streaming service.

William Hill

This is one of the most famous names in bookmaking. William Hill is one of the biggest bookmaker operations in the world and because of all that experience and trading power, they are consistently reliable when it comes to good odds. They have the power to trade at lower margins. On top of that, you have a website which is just jammed full of some tremendous betting opportunities.

The sportsbook is extensive and on top of that, they do deliver a tremendous amount of betting bonuses. Just visit their promotions page and you will see how much extra they offer their existing customers through their bonus. There are bet boosts, enhanced odds, extra places on horse racing and golf, and their popular golden goal promotion. William Hill, as expected,  have a huge racing section on their website and top account management.

Paddy Power

Paddy Power is pretty much the epitome of a bonus bookmaker. They have always been one of the front runners when it comes to launching unique and frequent betting bonuses. That has helped give them such a big identification in the market, along with their edgy best-mate vibe. There’s no heirs and graces with Paddy Power but for all of their publicity stunts and social media presence, they deliver a great service.

They are another of the top bookmarks who offer such a good sportsbook, which of course is the staple of any operator. That has to be in place and it is probably one of the more user-friendly websites as well. It just grabs and holds your attention, but with features like live streaming, high-quality racing, virtual sports, stacks of bonuses and a decent welcome bonus to top it all off, they remain one of our top picks for online betting.
