Referral marketing software for UK small businesses: what to check

What to take away

Five tools carry most of the UK small business marketMention Me, ReferralCandy, Referral Factory, Viral Loops and LoyaltyLion.
Three tests decide the winnerthe price in pounds, the data protection duties, and the integrations your shop already depends on.
Most platforms charge a monthly fee, a fee per active advocate, or a share of referred revenue, so model the cost at your real referral volume.
Ask for written UK pricing and a completed data protection questionnaire before any trial starts.

Named tools for a UK shortlist

Mention Me is London-based and sells on annual contracts. It publishes no list price, so expect a quote and a minimum term. It suits retailers with a busy order book.

ReferralCandy lists its plans in US dollars and charges a monthly fee plus a share of referred sales. Its Shopify app is the usual route in for small shops.

Referral Factory sells a no-code campaign builder, so you can launch without hiring a developer. Its entry tier targets low referral volumes.

Viral Loops runs template campaigns covering waitlists, milestones and friend referrals, with plans tiered by volume. It suits product launches as much as shops.

LoyaltyLion is London-based and prices on monthly order volume, so the fee climbs as the programme works. Referrals sit alongside points and reward tiers.

Talkable quotes per client and targets larger e-commerce brands, so it rarely wins on price for a micro-business.

US and European vendors bill in dollars or euros, so the sterling cost moves with the exchange rate. A UK VAT-registered business usually accounts for overseas digital services through the reverse charge.

Data protection duties that shape the shortlist

Referral tracking records personal data: the advocate's identity, the friend's email address, the purchase, and the link between them. If you run a referral programme, you process that data under the UK GDPR, as implemented by the Data Protection Act 2018.

UK GDPR referral data duties

Advocate's identity recorded
Friend's email address stored
Purchase data linked to referral
Lawful basis identified
Consent and retention set
Deletion requests handled
Reward terms clear before sharing

The ICO's UK GDPR guidance covers lawful bases, consent, retention and individual rights. Our guide to GDPR-compliant referral tracking sets out the practical steps, from the first shared link to a deletion request.

Advertised referral offers also fall under the CAP Code, enforced by the ASA, so reward terms must be clear before anyone shares a link.

Integrations that decide the shortlist

A native app for your shop platform saves weeks of work. Check for Shopify, WooCommerce, BigCommerce and Squarespace support. Then check email tools such as Klaviyo and Mailchimp, because invites usually leave by email.

In-store referral matters too. If customers join at the till, the software needs an EPOS link, or a staff workflow that issues and tracks codes by hand.

Fraud checks and payout rules

Referral programmes attract self-referral and duplicate-account attempts. Ask how the tool spots a referral from the same device, address or card, and whether that check runs before or after the reward is paid.

Reward reversals matter as much as approvals. If a friend returns the order, the software should claw the reward back or hold the advocate's balance as pending, and you need that rule written down before launch.

A short selection sequence

Write down the reward you can afford in pounds, and the margin it comes from.
List the systems the tool must feedshop platform, email, till, and accounts.
Ask for written UK pricing at three referral volumes: low, expected, and double.
Send a data protection questionnaire covering lawful basis, retention and deletion.
Run a one-month paid pilot and compare referred revenue with the fee.

What the fee has to earn back

Since referral programme ROI varies by sector, judge a fee against your own gross margin rather than a headline rate. A 5% revenue share looks cheap at a 60% margin and expensive at 15%.

Common questions

How much does referral marketing software cost in the UK?

Small business plans commonly start around £20 a month and rise past £150 once you add volume, payouts and support. Quote-only tools sit above that band.

Can a small business run a referral programme without software?

Yes. A shared spreadsheet and manual codes can work below roughly a hundred referrals a year. Software earns its fee when attribution, payouts or fraud checks take a day a month.

Does referral marketing need consent under the UK GDPR?

Not always. Consent is one lawful basis, but legitimate interests can also apply. Record that assessment and give people a clear way to object.
