Betfair Sign Up Offer & Bonus Code (November 2026)

Betfair bonus code ZSKAOL: added by the offer page

ZSKAOL is Betfair’s own promo code for its Sportsbook welcome offer. Betfair’s terms say to click the offer’s banner advert, which takes you to the sign-up journey with the code entered automatically, and that the code cannot be entered manually. On the offer page our Visit Betfair button opens, the first step reads ‘Join Here with promotion code ZSKAOL’.

Betfair Casino has its own welcome offer and code, and Betfair’s Exchange promotions page showed none:

The Sportsbook offer can’t be used with any other offer or sign-up offer, so decide which one you want before you join.

How to claim the Betfair sign-up offer

1. Open Betfair using the button above and choose to join.

2. Enter your details (the offer page adds the code ZSKAOL for you; it cannot be typed in). Your age and identity are checked at this stage.

3. Set a deposit limit you are comfortable with — licensed sites let you do this at sign-up or in your account settings.

4. Deposit at least £10 with a payment method the offer accepts. Only Pay by Bank, debit card or Apple Pay deposits qualify.

5. Betfair gives you 30 days from opening your account to make the deposit and the qualifying bet.

6. Place the qualifying bet at minimum odds of Evens (2.0).

7. Your free bets are credited as described in the terms. Use them before they expire (30 days).

Betfair Bet £10 Get £50: what counts as the qualifying bet

The qualifying bet is a bet of £10 or more on the Betfair Sportsbook at odds of 1/1 (2.0) or bigger, after a deposit of at least £10, all within 30 days of opening your account. Betfair’s terms add:

• You can’t take part if you have, or have ever had, a Betfair account, and your account must be registered in the UK or Republic of Ireland.
• Unmatched, unsettled and void bets don’t count, and neither do ‘same market’ bets on the Sportsbook.
• Cashed-out and partly cashed-out bets are excluded, as are bets placed wholly or partly with free bets.
• Canadian, Goliath, Heinz, Lucky 15, Lucky 31, Lucky 63, Patent, Super Heinz, Trixie and Yankee bets are excluded.
• If Betfair has emailed you to say you are excluded from promotions, you won’t qualify.
• Phone verification needs a device that can receive an SMS.

How Betfair’s five £10 free bets work

Once the qualifying bet has settled, Betfair adds 5 × £10 Sportsbook free bets to use on bet builders, accumulators or multiples on any sport. You can see them in the ‘My Bonuses’ tab at the top of Betfair’s website. They are valid for 30 days after they are awarded, and free bet stakes aren’t returned with winnings.

As an illustration only: a £10 free bet on a treble at combined odds of 4.0 returns £30 if all three selections win (£40 minus the £10 free bet stake). If one selection loses, it returns nothing. Odds of 4.0 imply roughly a one-in-four chance, so expect most bets like this to lose. Work out other prices in our bet calculator with “Free bet (stake not returned)” ticked.

How the Betfair offer compares

A £10 qualifying bet unlocks £50 in free bets — £5.00 in free-bet credit per £1 staked, not cash. Of the 15 UK sign-up offers we list, 4 give more free bets per £1 of your own money (level with Betfred). Its minimum odds of Evens (2.0) are harder to meet than 4 of the 15 offers with published minimum odds.

Free bet stakes are normally not returned. As an illustration only: a £5 free bet that wins at odds of 2.0 returns £5 in winnings, not £10. Work out other prices with our bet calculator, which has a free bet (stake not returned) option, or see how free bets work in our free bets guide.

Betfair payment methods

For this offer: Only Pay by Bank, debit card or Apple Pay deposits qualify. Credit cards cannot be used for gambling in Great Britain.

Safer gambling tools at Betfair

As a Gambling Commission licensee, Betfair must offer deposit limits, time-outs and self-exclusion in your account settings, and it takes part in GAMSTOP. Use them before you need them.

Betfair Casino welcome offer

Betfair runs a separate sign-up offer for its casino. It is not part of the betting offer above: since 19 January 2026, Gambling Commission rules say offers in Great Britain cannot require you to use both betting and casino games.

Betfair Casino promo code CASF51: how the free spins work

Betfair Casino’s welcome offer is for new customers aged 18 or over in the UK or Republic of Ireland who have not played Betfair Casino, using one account. Register with the code CASF51. Betfair doesn’t use the words ‘no deposit’, but under its terms the first 50 spins need no deposit:

• Opt in on the promotion page, then launch Crabbin’ For Cash Extra Big Catch Jackpot King or another eligible game and accept the offer. You get 50 free spins worth 10p each, and all of them play on the game you launched.
• After using them, opt in again in the Casino promotions hub, then deposit and spend at least £10 on eligible Jackpot King games. The next 50 spins, also 10p each, are added straight away on the game where you qualified. Deposits by e-wallets such as PayPal, Neteller and Moneybookers don’t count, and the terms give no deadline for this step.
• Each set of spins expires 7 days after it is awarded. Betfair says winnings are paid in cash; its offer terms don’t mention a wagering requirement.
• The six eligible games are all Jackpot King slots: 7s Deluxe Fire Wheel, Crabbin’ For Cash Extra Big Catch, Eye of Horus, Fishin’ Frenzy, The Goonies and Betfair Even Bigger Bananas. Some may not be available on Betfair’s iOS app, but they are on a mobile browser or desktop.

Compare it with other casino offers on our free spins page and no deposit free spins page.

Betfair sister sites

Betfair is on more than one Gambling Commission licence. On 5 November 2026, the Commission’s public register listed betfair.com under 39439 (PPB Counterparty Services Limited: betting and virtual betting), 39426 (PPB Entertainment Limited: casino and bingo) and 39435 (Betfair Casino Limited: casino). Those licences list one other site:

• Paddy Power paddypower.com

Sister sites share an operator, but their offers can differ: check each site’s own terms. Under Gambling Commission rules, a self-exclusion covers all gambling with the licence holder, so every site on its licence, unless you asked for a narrower one, and the operator must take reasonable steps to apply it to your accounts with its group companies too.
