What is a Betting Promo Code/Bonus Code?

A betting promo code is needed to unlock promotions and bonuses offered at some betting sites. Normally only available to new customers, promo codes are linked to specific offers. Promo codes must be entered at the time of signing up or processing an opening deposit. In some cases they can be entered upon placing first bets. Betting promo codes generally surround free bets and bonuses, although a small number of additional offers are available to punters in the UK.

The likes of Bet365, BetVictor and UniBet are among the bookies not to use promo codes for their sportsbook customers at present. Bettors at safebettingsites can rest assured that our recommended promo codes come from reputable bookies. We also update this page on a regular basis, ensuring that bonus codes are up to date. In order to give punters a better understanding of how betting promo codes work, below is both a winning and losing example of using them.

How We Rank Betting Promo Codes

As with everything in which we do here at safebettingsites, our promo code reviews are completely objective. We only recommend betting promo codes from fully licensed and regulated bookies. This includes both established operators and new betting sites. Our experts consider the following factors when ranking promo codes:

  • Safety – Our recommended betting promo codes come from nothing but trustworthy and secure bookies. All customers signing up and wagering on such platforms are doing so safely. A license from the UK Gambling Commission is held by each, while steps are taken to ensure for the safety of punters at all times. Operators also promote responsible gambling at all times. In fact, many are associated with BeGambleAware ( 
  • Eligibility – Once a promo code has been entered, qualifying for your bonus or free bet should be relatively straightforward. There are some bookies who seemingly look to make life as hard as possible for punters, meaning that they do not make it onto our list. 
  • Deposit Methods – The best betting promo codes are also realistic in terms of the deposit methods available. While this varies between bookies, generally speaking, a number of options are available when it comes to making qualifying deposits. 
  • Time – Our recommended promo codes also provide punters with sufficient time to claim bonuses/free bets and meet the wagering requirements. 
  • Rewards – Ultimately, the rewards available through a betting promo code must be worth the time and effort. If a small bonus or limited free bet is all that is up for grabs, it is unlikely to be worthwhile for punters.

Types of Betting Promo Codes

Before you begin locating betting promo codes, it worth considering the different types available to punters in the UK. When it comes to sports betting, the following bonus codes are likely to be available:

Deposit Bonus

The simplest and most common type of betting promo code surrounds a deposit bonus. Bookies will clearly indicate the percentage of the first deposit that will be matched, along with the maximum bonus amount. For example, a 100% welcome bonus up to £100. This means that an opening deposit of £20 will result in an opening balance of £40. 

No Deposit Bonus

Unfortunately, no deposit bonus offers are hard to come by today. More commonly associated with casino bonuses, a no deposit bonus is awarded to players who sign up for a new account. The bonus on offer is normally significantly smaller than a normal deposit bonus, perhaps even as little as £10. Online casinos are likely to offer free spins or a small bonus.

Free Bet

Another common type of promo code is a free bet offer. A free bet or free bet credits will be awarded for those meeting the qualifying conditions. For example, bet £10 get £30 worth of free bets.   

Risk Free Bet 

Here, those who lose their first bet after signing up will see their stake returned, in the form of a free bet. For example, you bet on your favourite Premier League football team or horse racing runner to win, only for them to lose the match or race. Your stake will be refunded up to anywhere between £10-£25. Those whose opening bets are successful will receive winnings as normal. Some such betting offers feature in the table at the top of this page. 

How to Sign Up & Redeem a Promo Code

Redeeming a betting promo code is a relatively simple process, however it can vary between bookies. Having found the bonus code you wish to take advantage of from our list of recommended operators, the first step is to register an account. To give punters a better understanding of how to sign up at a betting site, the following is a useful step by step guide:

Step 1: Visit Sportsbook

Enter your chosen betting site or download the bookie’s mobile app.

Step 2: Locate Sign-Up Page

Click on the “Join Now” or “Register” option, normally located in the top-right hand corner of the page.

Step 3: Sign Up

Complete the registration form. This includes entering your full name, email address and date of birth. Some bookies may require new players to create a username and password.

Step 4: Verify Your New Account

Verify your new account via email.

Step 5: Deposit

Deposit funds and start betting.

Depending on the bookie, promo codes must be entered in order to claim bonuses and rewards. This process differs between betting sites, with codes having to be entered at the time of registering, depositing or placing bets. A box with the heading “Do you have a promo code?” or “Enter Bonus Code” will be available, with punters then having to ensure that they enter the code correctly. This means taking into account any uppercase and lowercase letters, as well as numbers. Double check your code before confirming! Any mistakes here can mean missing out on a welcome bonus or free bet. 

Betting Promo Code Terms & Conditions

No matter which bookie you sign up with, betting promo code terms and conditions are likely to be in play. However, there is nothing for new customers to worry about, with most of the T&Cs being very simple to follow. With that being said, the following are the main terms and conditions in which punters must look out for when utilising betting promo codes:

Minimum Deposit

With no deposit bonus offers being hard to come by in the UK today, a qualifying deposit must normally accompany a promo code. A deposit of at least £10 is generally required. However, this can be less in some cases.   

Minimum Bet

An opening deposit may be enough to redeem a promo code, however it is more likely that a bet must also be placed. The minimum stake is set at £5 or £10 in most cases.

Minimum Odds

In order to not make things too easy for punters, qualifying bets, as well as bets placed using bonus funds, must meet minimum odds requirements. Ranging from bookie to bookie again, this prevents bettors from simply wagering on the favourites. 

Wagering Requirements

Punters might have to wager bonus funds a particular number of times before withdrawals can be made. This could be anywhere from x1 or x30 the total bonus amount. Those using free bets will only be able to take home winnings made.

Maximum Bonus

When it comes to a welcome bonus, a maximum bonus amount will be set. Whether it be £50, £100 or £200, bookies generally look to cater for the masses. 


Betting promo codes will likely only be available for a certain period of time. Once this date has passed, promo codes will become ineligible, with an alternative normally becoming available. 

Payment Methods

The method of payment used by new customers can also impact upon your ability to redeem a promo code. An increasing number of bookies state in their T&Cs that a debit card must be used. As a result, e-wallets, such as PayPal and Skrill, or bank transfers will not qualify. 

Cash Out 

Cashed out bets are likely to be ineligible.

Are Promo Codes Available to Existing Customers?

While being rare, promo codes are occasionally available to existing customers at UK betting sites. A qualifying bet or deposit is normally enough to unlock an ongoing promotion. However, in some cases, a bonus code must also be entered. Examples could be surrounding an accumulator boost, acca insurance, money back special, best odds guaranteed or enhanced odds offer. Bookies will generally make it clear as to when such promotions require a bonus code to qualify. 

Other Popular Betting Promotions This Month

Whether a promo code is necessary or not, there are a host of additional betting promotions available to punters in the United Kingdom this month. Delivered by only safe and reliable bookies, the following are some of the offers in which we suggest checking out. Each comes with its own benefits, as well as full T&Cs. 

Bottom Line on Betting Promo Codes

For those with experience of betting online, promo codes will be familiar ground. However, for newcomers, they take some understanding. The first thing to remember is that failure to enter the relevant promo code, at the required time, will mean missing out on a potentially rewarding reward. We have listed some of the best betting promo codes available today, with our experts constantly being on the lookout for new additions. Having found a promo code that suits your betting needs, look into the terms and conditions, before potentially signing up. Promo codes are becoming increasingly common, with many of the leading bookies utilising this option. 


My code didn’t work. What is my next step?

In this event, be sure that you have entered the promo code correctly, using all upper and lowercase letters as they appear, along with any numbers. Next, be sure to check that the promo code has not expired. If nothing is wrong here, contact the customer service team of your chosen bookie.

I didn’t receive my bonus/free bet after entering a promo code. What can I do?

Firstly, it may take time for bonus funds or free bets to be credited. Punters may have to wait up to 48 hours in some cases. However, if you have still not received your reward, be sure to check that you met all of the promo code terms and conditions. If still unsure, contact the customer service team.

How can I keep up to date with the latest betting promo codes?

Signing up for newsletters from your bookmakers is an easy way to stay up to date with the latest promo codes and bonus offers. Meanwhile, we recommend regularly visiting this page, with our experts adding new codes and betting sites on a consistent basis.

Is there a promo code for free bet offers?

In some cases yes. Placing an opening bet is the standout qualifying requirement, however some operators will introduce a promo code on top of this.

Are promo codes available for existing customers?

The majority of bookmakers will offer some form of promotions to customers who are already signed up. However, the majority do not require a bonus code to be eligible. Promo codes for existing customers are applicable in some cases however, so be sure to look at the terms and conditions before looking to qualify.
