Why referrals matter
People pick a plumber they've heard good things about.
You're working inside someone's home, often when something's gone wrong. That's why so many homeowners ask friends, family or a neighbour who they used before they search online.
Trust comes first
A leak or a dead boiler is stressful. Customers want someone a person they know has already vouched for.
Neighbours have similar homes
Houses on the same street often share boiler ages, pipework and problems. One good job can be relevant next door.
You probably already get referrals
Good plumbers hear “my sister gave me your number” all the time. It just isn't written down anywhere.
Informal means untracked
Without a record, it's easy to forget who recommended you, and the thank-you never happens.
How it fits
It slots in after the job, not instead of it.
ReferralLoop adds referral tracking around the way you already work. It doesn't replace anything you already use.
What ReferralLoop adds
- A referral link and QR code for your customers
- A list of every referral and where it came from
- Job value against each referral
- Reward tracking so nobody's forgotten
- A message helper for contacting the new customer
What you keep doing your way
- Your CRM or job management tool
- Booking and scheduling
- Quotes and invoicing
- Phone calls and site visits
- Your boiler service reminders
Example programme
A simple £25 thank-you, earned when the job's done.
Paying out when the referred job is completed means you only reward work that actually happened. It's an example — some plumbers prefer money off their next service.
You choose your own reward, amount and when it's earned. ReferralLoop tracks it; you give the reward yourself.

Timing
Best times to ask for a referral
Moments that tend to work well for plumbing and heating businesses. They're suggestions, not rules — you know your customers best.
- 1
After a successful repair
The leak's fixed and the relief is real. A quick mention lands naturally.
- 2
After a boiler service or install
Heating's working, paperwork's done — a good moment to leave the QR card.
- 3
When they compliment the work
If they say “I'll tell my neighbour about you,” give them the link there and then.
- 4
In your completion message
Add one line and the link to the text or email you already send.
Sharing
Where to share your link
Every business gets one referral link. Send it wherever you already talk to customers.
- WhatsApp after a job
- Invoice footer
- Completion email or text
- Boiler service follow-up
- Google Business profile post
- Facebook page
