What a refer-a-friend bonus is

Refer-a-friend rewards you for bringing a new customer to a bookmaker. You share a personal link or code; your friend signs up through it; and once they’ve met the conditions, you both get a bonus — usually a free bet. It’s word-of-mouth marketing that the bookmaker pays for, because a referred customer is cheaper to acquire than an advertised one.

How the terms really work

The reward is never as simple as “refer someone, get paid”. Both sides have hoops:

  • Your friend must be genuinely new — no existing account, matching device/IP/payment flags can disqualify.
  • They must deposit a minimum amount.
  • They must place qualifying bets — often a set stake at minimum odds — before either of you is paid.
  • The reward is a free bet — commonly SNR, worth ~70–80% of face value.
  • Caps on how many friends you can refer, and how much you can earn.
  • Wagering may apply to the free bet itself before winnings withdraw.

So the trigger isn’t sign-up — it’s your friend becoming an active, depositing bettor.

A worked example

“Refer a friend, you both get £20 in free bets. Friend must deposit £10 and bet £10 at min odds 1.5.”

  • Your friend deposits £10, places a £10 qualifying bet (real money, real risk to them).
  • Once settled, you each receive a £20 SNR free bet, real value ≈ £14–£16 each.
  • If the free bets carry their own wagering, the real value drops further.

The honest arithmetic: to get your ~£15 of free-bet value, your friend has to put £10 of their own money at risk and become a real customer. You’re effectively being paid a small, restricted amount to recruit someone into gambling. That’s worth thinking about before you send the link.

The catches

  • Both-sided conditions — you’re not paid until your friend bets.
  • SNR free bets — ~20–30% below face value.
  • Referral caps and per-account limits.
  • Fraud clauses — self-referral, duplicate accounts and fake friends are void and can get accounts closed.
  • You’re recruiting a gambler — the ethical catch the terms don’t mention.

How to judge whether it’s worth it

  1. Confirm the reward type (free bet vs cash) and apply the SNR discount.
  2. Read what your friend has to do — and whether you’d genuinely recommend the site anyway.
  3. Only refer people who already bet and asked for a recommendation. Never pressure someone into signing up for your bonus.
  4. Compare the underlying bookmaker on merit in our best betting sites.

Honesty note

This is the one bonus with a social dimension, and it deserves a direct word: a refer-a-friend offer pays you to bring another person into betting. The modest, restricted free bet you receive is not a good reason to encourage a friend — especially anyone who doesn’t already gamble or who might be vulnerable — to open an account. Only ever pass on a genuine recommendation to someone who was going to bet regardless. The bonus should never be the motive. And if your own betting is being shaped by chasing these rewards, take a break — play responsibly.
