Ask most service businesses where their best customers come from and you’ll hear the same answer: recommendations. A happy client tells a friend, the friend gets in touch already half convinced, and the job is won with very little effort. Referred customers often arrive with more trust and fewer questions about price. A simple referral scheme makes that happen more often.
The trouble is that most businesses leave referrals to chance. They’re grateful when one turns up, but they don’t do anything to make them happen more often. A referral scheme changes that. It turns a nice surprise into a steady, deliberate source of new work.
This guide is for UK service businesses of any size, from trades and clinics to accountants and agencies. It covers how to design a scheme, when to ask, how to track it and how to keep it within the rules.
Check you’re ready for more referrals
A referral scheme amplifies what’s already there. If customers are happy, it helps more of them say so. If service is patchy, it won’t fix that, and it might expose it to more people. Before you start, be honest about a few things:
- Do customers regularly tell you they’re pleased with the work?
- Are your reviews mostly positive and recent?
- Do you already get some referrals without asking?
- Could you handle more enquiries without service slipping?
If the answers are mostly yes, you’re in a good position. If not, fix the service first. It’s the cheapest marketing you’ll ever do.
Decide what, if anything, you’ll offer
Not every referral scheme needs a reward. Many people recommend businesses simply because they like them and want to help a friend. Sometimes the most effective scheme is just asking, clearly and at the right moment. That said, a well-chosen incentive can give people a reason to act rather than just meaning to.
Common options include:
- A reward for the referrer: a discount on their next job, account credit, a voucher or a gift.
- A reward for the new customer: a welcome discount or an added extra on their first job.
- Rewards for both: often the most persuasive, because the referrer feels they’re giving their friend something, not just earning a bonus.
- A charity donation: a donation made for each successful referral, which suits businesses where cash rewards feel awkward.
Keep the reward proportionate to what a new customer is worth to you, and make sure it still makes financial sense if the referral scheme is more successful than you expect. Rewards tied to your own services, such as credit or a free extra, also keep people coming back.
Decide what counts as a successful referral
Be clear about when a reward is earned. Is it when a friend gets in touch, books a first appointment, or pays their first invoice? Paying on a completed, paid job is usually the safest option. Set out any limits too, such as a maximum number of rewards per person, or excluding existing customers and people who’ve already enquired.
The best referral schemes are simple enough to explain in one sentence. If it needs a leaflet of small print, most people won’t bother.
Ask at the right moment
Timing matters more than the reward. People are most likely to recommend you when they’re feeling pleased with what you’ve done. Good moments include:
- Just after a job is finished and the customer has seen the result.
- When a customer thanks you or pays a compliment.
- Straight after they’ve left a positive review.
- At a milestone for ongoing clients, such as a year working together or a successful project.
Build the ask into your normal process so it doesn’t depend on someone remembering. That might be a line in your job completion email, a card left after an appointment, a message a few days after the invoice is paid, or a question at the end of a review meeting.
Be direct and specific. “If you know anyone who needs a new boiler, we’d really appreciate the introduction” works better than a vague “tell your friends about us”.
Make it easy to refer
Every extra step loses people. Give referrers a simple way to pass you on:
- A short message they can forward by text or email, with a link to a page about the scheme.
- A personal referral code or link, so you know who sent whom.
- Printed cards they can hand over, for businesses where face to face matters.
- A simple web page explaining the offer, how it works and the terms.
A good general rule is to ask the referrer to share your details with their friend, rather than asking them to hand over their friend’s contact details to you. It’s simpler, feels less pushy, and avoids data protection questions about contacting people who haven’t dealt with you before.
Track it properly
Without tracking, you won’t know whether the referral scheme is working, and you’ll struggle to reward people fairly. At minimum, record:
- Who referred each new enquiry.
- Whether the enquiry became a customer, and the value of the work.
- When the reward was earned and when it was given.
A spreadsheet is fine to start with. If you use a CRM, add a referral source field and a referrer field so it’s recorded as part of the normal enquiry process. Ask every new enquiry how they heard about you, even if they didn’t use a code. Many referrals happen by word of mouth and never touch your link.
Thank referrers promptly, whether or not the referral turns into work. A quick personal message goes a long way and makes them more likely to refer again.
Keep it within the rules
Most simple referral schemes are straightforward, but there are a few things to keep in mind. This isn’t legal advice, so take proper advice for your own situation.
- Clear terms: publish simple terms covering who’s eligible, what the reward is, when it’s earned and any limits or end date. Advertising rules require promotions to be clear and not misleading.
- Personal data: handle referrers’ and referred customers’ details in line with UK data protection law and your privacy policy. Don’t add referred people to marketing emails unless you have the right permission to do so.
- Reviews are separate: don’t link rewards to leaving reviews. Google’s policies prohibit incentivised reviews, and UK consumer law treats fake or incentivised reviews seriously.
- Regulated sectors: if you work in areas such as financial services, legal services or healthcare, there may be specific rules about referral fees, inducements or promotions. Check with your regulator or professional body before launching.
- Tax: cash rewards and gifts may have tax implications, particularly for business-to-business schemes. Check with your accountant.
Review and refine
After a few months, look at the numbers. How many referrals came in, how many became customers and what were they worth? Who are your most active referrers? Consider a personal thank-you or something extra for them. If take-up is low, test changes one at a time: the timing of the ask, the wording, or the reward itself.
