Betfair is a generous and reliable bookie in the UK, and its sign-up bonus certainly reflects this. When you create an account at Betfair and place a minimum bet of £10 on any market with minimum odds of 1/1 (2.0), you qualify for a sign-up bonus of £50 in free bet builders, accumulators, or multiples. To activate this bonus, which will be valid for 30 days, you need to use the promo code ‘ZSKAON.’
The Betfair welcome offer is available right now at Betfair, which makes the bookmaker one of the best betting sites in the UK for new bettors looking for generous sign-up promotions. It offers great value with a 5x return on your qualifying wager, and you can use the offer across all major sporting events, including football, soccer, tennis, cricket, boxing, and more.
Here is a simple step-by-step guide to claiming your Betfair sign up offer.
Go to the Betfair website or app: Browse the Betfair website and click/tap on the registration button. For a faster sign-up process, use the links in this guide, and they will redirect you to the Betfair sign-up form, where you can register seamlessly. You can also download the Betfair app and sign up using your mobile device.
Enter your details: On the first page of the registration form, enter details such as your gender, name, date of birth, country, postcode/address, phone number, email, and password. You also need to set up a security question, choose your preferred currency, and set up a deposit limit.
Enter promo code: To activate the Betfair sign up bonus, remember to enter the promo code ZSKAON in the designated field.
ID verification: Once you provide all the required details, click/tap on the sign-up button at the bottom of the form to register. You’ll then need to verify your email and phone number.
Deposit funds: To qualify for the sign-up bonus, you need to deposit at least £10 using a debit card or Apple Pay.
Place a qualifying bet: Head to the sportsbook section and wager £10 on any market with minimum odds of 1/1 (2.0). It could be a simple match winner bet, an accumulator across different sports, or a bet builder combining multiple outcomes.
Claim your £50 in free bets: Once you make a qualifying bet, the bookmaker will credit £50 in free bets into your account.
Betfair rolls out promo codes from time to time, and to claim your Betfair sign up offer, you need to enter the right promo code. These promo codes are usually designed to create a sense of exclusivity and activate the right bonus offer. And since Betfair offers both an online casino and sportsbook, you must ensure you’re using a promo code for the right section. For instance, the Betfair sign up offer promo code for sportsbook (sports betting) is ‘ZSKAON’ while for online casino is ‘CASAFS.’
In the UK, you must be over 18 years of age to sign up at Betfair and use its promo codes. And if the promo code is meant for new punters, you can’t use it if you’re already an existing bettor.
Yes, the Betfair sign-up bonus is quite generous, but it comes with some terms and conditions that you must follow when claiming and using the offer. First, the offer is only available for new punters from the UK and the Republic of Ireland. You must also use the ZSKAON promo code when signing up to activate the offer. As well, you must deposit with debit cards or Apple Pay: deposits from other payment methods like Neteller and PayPal, among other options, don’t qualify for the free bets.
Another important term of the Betfair sign up offer is that you must wager at least £10 on any market, at odds of 1/1 (2.0) or more. You must also use the bonus within one month of creating your account, since the offer expires in 30 days after registration. In addition, the offer only applies to the sportsbook, not wagers made through the Betfair Exchange.
So, before claiming this bonus, we recommend that you read the terms and conditions carefully to get the most out of the offer.

The sign-up bonus at Betfair is one of the most generous welcome offers for UK bettors. Let's look at some of the advantages of claiming this bonus compared to offers at other UK sports betting sites.
You get a larger bonus: Betfair’s sportsbook welcome offer is one of the largest in the UK. Most bookmakers will only give you between £20 and £35 in free bets after signing up, which doesn't do much for you. But with Betfair’s £50 in free bets, you can wager on more of your favourite games or markets, enjoy betting for longer without depositing additional funds, and increase your potential winnings.
Eligible for a wide range of sports and markets: Compared to other UK betting sites, Betfair’s sign-up bonus gives you more flexibility. For example, after claiming the offer, you can use it to wager on a wide range of betting options, including bet builders, accumulators, and multiples. In addition, you can use the offer to even place wagers on the Betfair Exchange. Other bookmakers will only let you use the welcome bonus on a specific sport(s), bet types, or a few markets.
Betfair's welcome bonus is more reliable: When you sign up and activate the Betfair sign-up bonus, you get up to 30 days to use the offer. At the majority of top UK bookmakers, you only have 7 days before the bonus expires.
While using the Betfair sign-up bonus, there are also some limitations that you need to watch out for. For example, free bet stakes are not returned with winnings. The offer also excludes certain bet types such as Canadian, Goliath, Lucky 63, Lucky 31, Lucky 15, Heinz, Super Heinz, Patent, Trixie, and Yankee.
Even so, if you use your £50 free bets and your wager wins, the winnings from the free bet (not including the free bet stake) will be added to your account, which you can withdraw if you wish. During our Betfair review, we didn’t see any mention of wagering requirements for the £50 free bets.
One of the biggest appeals of the sign-up offer at Betfair is that you get to claim the bonus even when you make a small deposit and wager. With just a £10 deposit and minimum wager, you get to claim your free bets to boost your betting experience.
We created a table to show you how the Betfair sign up offer stacks up against other top UK bookmakers.
The Betfair sign up offer is meant to encourage new bettors in the UK to sign up at the bookmaker, promising them a bankroll boost once they create an account, deposit, and make a qualifying initial wager. This bonus enhances your overall betting experience, but you must use it wisely. Here are the top tips to maximize your Betfair sign up offer.
Manage your bankroll: To get the most out of your bonus, you need to manage your bankroll effectively by setting bet limits. Instead of placing one large bet in one go, we recommend that you divide your £50 free bets into small bet sizes. This helps you bet for longer and can also increase your potential winnings.
Focus on markets with better value: Each sports betting option, whether football or cricket, has markets that offer better odds and high payouts. So, we recommend that you use the bonus on those profitable bet markets to get the most value from the offer.
Use bonus strategically: This can mean lots of things, but the best one is using the bonus on value bets. Do your research to identify undervalued markets or where the bookmaker assigns inaccurate odds, based on your real-time research. You can also use the bonus on in-play bets to take advantage of the changing odds and momentum shifts.
When claiming and using the Betfair sign up bonus, we recommend that you bet responsibly. Don’t try to chase any losses to recover lost bets or place bets with emotions. Instead, take a break, re-evaluate your betting strategy, and make smart bets based on informed decisions.
Betfair also offers responsible gambling tools that can help you manage your betting habits, whether you’re betting with the Betfair sign up offer or your deposited funds. These tools include deposit limits, loss limits, the Budget Calculator, time out, Gaming Time Check, and self-exclusion. Just click/tap on the ‘Safe Gambling’ button in the top right corner of the bookmaker’s homepage to access Betfair’s comprehensive responsible gambling page.
