Looking to boost your betting rewards while sharing the fun with friends? Many UK bookmakers now offer generous refer a friend bonus programmes, giving you and your mates extra perks just for signing up and placing bets. These promotions are a great way to earn free bets, cash bonuses, or other rewards while enjoying your favourite sportsbooks.
Refer a friend bonuses reward existing customers for introducing new players to UK bookmakers. Rewards range from £10-£100 per referral depending on the bookmaker and betting type. Top offers include Paddy Power (£20 cash per friend), Betfair (£20 free bets, up to £100 total), and Spreadex (risk-free £100 spread bet). This guide explains how these programmes work, compares the best current offers, and shows you how to maximise your referral earnings.
In this guide, we’ll explore the top UK bookmakers with referral bonuses, how these programmes work, and how to make the most of them.
How Refer a Friend Bonus Programmes Work
Refer a friend bonus programmes are promotional offers provided by UK bookmakers to encourage existing players to introduce new customers to their platform. These programmes create a mutually beneficial experience where both the referring player and the new customer gain rewards.
The Referral Process
The process for participating in a refer a friend scheme is straightforward:
| Step | Action | What Happens |
|---|---|---|
| 1 | Invite a Friend | Log into your account, access the referral section, share your unique link via email, text, or social media |
| 2 | Friend Signs Up | Your friend creates a new account using your referral link or code |
| 3 | Friend Places Bets | They place qualifying bets within the specified timeframe (usually 7-28 days) |
| 4 | Reward Credited | Once requirements are met, the bonus is credited to your account (typically within 24-48 hours) |

Paddy Power: Friends with Benefits
Paddy Power offers one of the most straightforward referral programmes in the UK betting market. Their “Friends with Benefits” scheme provides:
How it works:
- Log into your Paddy Power account and navigate to the “Refer A Friend” section
- Share your unique referral code with friends via email, text, or social media
- Your friend signs up using your code and stakes at least £10 on sports at minimum odds of 1/2 (1.50)
- Once they place their qualifying bet, you receive £20 cash credited directly to your account
The key advantage of Paddy Power’s scheme is that you receive cash, not free bets — meaning you can withdraw immediately without wagering requirements. With up to 10 referrals per month, you could potentially earn £200 monthly.
Spreadex: The Most Generous Referral Programme
Spreadex offers one of the most comprehensive referral programmes among UK bookmakers, catering to both spread betting enthusiasts and fixed odds bettors.
Spread Betting Referral Bonus
- Log into your Spreadex account and navigate to the “Refer A Friend” section
- Invite a friend via email from your account dashboard
- Your friend must place five qualifying sports spread bets with a minimum £2 stake per bet, each capable of winning or losing £20
- After the qualifying bets are completed, you receive a risk-free £100 Total Goals spread bet
- If the bet loses, Spreadex refunds your losses within 24 hours; if it wins, you keep all the profit
Fixed Odds Referral Bonus
- Send an invitation to a friend via email or text from your Spreadex account
- Your friend must place a minimum of £10 in fixed odds bets at odds of at least 1/2 within 28 days of registering
- Once their bets are placed, you earn £10 cash credited directly to your account
Spreadex’s referral scheme offers two types of rewards — one tailored for spread betting and one for fixed odds betting — giving you the flexibility to choose the bonus that suits your betting style. There’s also no cap on the number of referrals, making it potentially the most lucrative programme available.
Betfair Exchange Refer a Friend
Betfair’s referral programme rewards you with £20 in free bets for each friend you introduce to the exchange:
- Share your unique referral link with friends
- Your friend must sign up and bet over £50 within 30 days of referral
- You receive £20 in free sports bets once they qualify
- Maximum of 5 referrals, for a total of £100 in free bets
Note that Betfair requires higher betting activity from your friend (£50) compared to Paddy Power (£10), but the rewards are comparable.
Smarkets Exchange Referral Programme
Smarkets offers a straightforward referral bonus where both you and your friend benefit:
- Both referrer and referee receive a £10 risk-free bonus
- Your friend must enter your unique referral code during signup
- Both accounts must be fully verified (ID and proof of address)
- Both must place bets with minimum liability of £20
- Maximum of 50 referrals per account = up to £500 potential
Smarkets does not award referral bonuses if your friend deposits via PayPal, Skrill, Neteller, or virtual/prepaid cards due to high levels of promotion abuse through these methods. Ensure your friend uses a debit card or bank transfer.
Unibet Refer a Friend Scheme
Unibet offers one of the most lucrative per-referral rewards, though with higher requirements:
- Earn £60 per friend referred once they wager £400 on sports betting or £1,000 in casino within 60 days
- Refer up to 3 friends for a maximum of £150 in bonuses
- Access your unique URL from the promotions section of the Unibet website or app
The higher wagering requirements mean this offer suits friends who are already active bettors rather than casual newcomers.
How to Maximise Your Referral Earnings
| Strategy | Description | Potential Benefit |
|---|---|---|
| Target active bettors | Refer friends who already bet regularly | Higher completion rate |
| Explain the process | Help friends understand qualifying requirements | Avoid failed referrals |
| Use multiple bookmakers | Refer same friend to different platforms | Multiply rewards |
| Time it right | Refer around major events (World Cup, Euros) | Friends more likely to bet |
| Choose cash over free bets | Prioritise bookmakers offering cash rewards | Immediate withdrawals |
Tax Considerations for UK Referral Bonuses
If you’re earning significant amounts through referral programmes, you should be aware of the tax implications:
- Trading allowance: You can earn up to £1,000 per year tax-free from “casual income” including referral bonuses
- Over £1,000: You must declare earnings on a self-assessment tax return and pay income tax on amounts above £1,000
- Regular referral income: If consistently earning from referrals, HMRC may consider it business activity requiring registration
Keep records of all referral bonuses received throughout the tax year. If you approach or exceed £1,000, consult an accountant for guidance.
Becoming an Affiliate: The Next Level
If you can deliver a steady stream of new customers to bookmakers — or even online casinos — you may want to consider becoming an affiliate instead of relying solely on refer a friend programmes.
- Commissions for every player referred (ongoing revenue share, not one-time)
- No cap on earnings — successful affiliates earn thousands monthly
- Professional tools and tracking dashboards provided
- Works across multiple operators simultaneously
- Requires much more effort — building traffic sources, maintaining websites
- Need to establish partnerships with operators
- Time investment before seeing significant returns
- Must comply with advertising regulations
Affiliate partnerships can be significantly more lucrative long-term, offering ongoing revenue share commissions rather than one-time bonuses. However, this requires building traffic sources and establishing partnerships with operators.
Terms and Conditions to Watch
Before participating in any refer a friend programme, always check these key terms:
| Term | What to Check | Why It Matters |
|---|---|---|
| Qualifying bet requirements | Minimum stake, odds, bet types | Determines if friend can easily qualify |
| Time limits | Days to complete requirements | Short windows may pressure friends |
| Payment method restrictions | Which deposit methods qualify | E-wallets often excluded |
| Household restrictions | Same address, IP, or payment method rules | Family members usually excluded |
| Bonus expiry | How long to use free bets/bonuses | Some expire within 7 days |
| Wagering requirements | Rollover needed before withdrawal | Cash rewards preferable to free bets |
Remember that betting should be enjoyable entertainment, not a source of income. Never pressure friends to sign up or bet more than they’re comfortable with. If you or someone you know is struggling with gambling, visit BeGambleAware.org or call the National Gambling Helpline on 0808 8020 133.
