Getting a new customer costs time, effort, and often money. Keeping an existing one costs almost nothing. Yet most tradespeople spend all their energy chasing new work and put zero effort into staying in touch with the customers they've already got.
Your past customers already trust you. They already know your work. When they need something done again, you should be the first person they think of.
Annual Service Reminders
If your trade involves anything that needs regular maintenance — boiler services, electrical inspections, gutter cleaning — you're sitting on a goldmine of repeat bookings. The problem is that most customers won't remember when their service is due. They rely on you to tell them.
Keep a record of every service job with the date and customer's contact details. Set a reminder for eleven months later. Send a simple message: "Hi Karen, your boiler is due a service next month. Shall I book you in?"
That one message is worth £80-120 in guaranteed work. Multiply it by a hundred customers and you've got a solid base of predictable income every year. Gaffer automates this entirely, sending WhatsApp reminders at whatever interval you set.
The Small Touches That Matter
Customers don't remember the technical details of what you did. They remember how you made them feel. And the small touches are what stick in their minds when someone asks "do you know a good plumber?"
Turn up on time. Every single time. Being punctual is so rare among tradespeople that it makes you memorable.
Clean up after yourself. Properly. Hoover the dust, wipe the surfaces, take your rubbish. Leaving a space cleaner than you found it is the single biggest driver of positive word-of-mouth.
Explain what you did and why, in plain English. A thirty-second explanation shows respect for the customer and builds confidence in the work.
Follow Up After the Job
A quick message the next day: "Hi Steve, just checking everything's working fine with the new tap. Give me a shout if you notice anything." Takes fifteen seconds and tells the customer you care about the outcome, not just getting paid.
Very few tradespeople do this. Which is exactly why it makes such an impression when you do.
Stay in Touch
You don't need to message customers every week. Just pop up on their radar occasionally.
A message at Christmas: "Merry Christmas from [your business]. Thanks for your custom this year." Simple, warm, costs nothing.
A heads-up about something useful: "British Gas are putting prices up again in April. If you've been thinking about upgrading your boiler, probably worth doing it before then."
Referral Rewards
"If you recommend me to a friend and they book a job, I'll take £20 off your next bill." Simple, clear, and it gives past customers a reason to actively mention you rather than just passively recommending you if someone happens to ask.
Why Repeat Customers Are Gold
New customer acquisition has a cost. Repeat customers cost almost nothing to retain. They already trust you, they don't haggle as much, they pay faster, and they're more likely to leave positive reviews.
A tradesperson with 200 loyal past customers who each need work once a year has a business that practically runs itself. Start building that base now. Be brilliant at the work, be easy to deal with, and stay in touch. The rest takes care of itself.
