The Real Cost of Missed Calls for Plumbers

Why every unanswered call costs plumbing businesses hundreds of pounds in lost revenue.

Genni Team

You're under a sink fixing a leak. Your phone rings. You can't answer, because your hands are full and you're in the middle of a job.

That call was a homeowner with a burst pipe emergency, willing to pay £800 for immediate call-out. They called the next plumber on Google. Job gone.

Sound familiar?

Plumbing is a Phone Business

More than almost any trade, plumbing relies on phone calls:

  • Emergencies - Burst pipes, no hot water, blocked drains
  • Urgency - People need help NOW, not tomorrow
  • High value - Average plumbing job: £250-600
  • Repeat business - Fix someone's boiler, and they'll call you for everything

But here's the problem: You're busy doing the work. And when you're working, you can't answer calls.

How Many Calls Are You Missing?

Here is the shape of it for a one-person plumbing business. These are assumptions, not measurements: put your own in. Our own line took 287 calls since August 2025, and most single-site businesses we see take twenty to sixty a month.

Calls a month, assumed: 40

Assumed answer rate while you are working: 30-40%

On those assumptions you are missing 24 to 28 calls a month.

What a missed call costs you

What a missed call is worth depends entirely on what you charge, so put your own numbers in. Here is the shape of it. None of this is measured: it is arithmetic on assumptions you should replace with yours.

  • Missed calls a month, from above: 25
  • Jobs won, if one in five of those enquiries converts: 5
  • Average job value: £350
  • Lost revenue a month: £1,750
  • On those assumptions, a year: £21,000

Halve it again, on the basis that you would have been too busy to take some of them, and it is still £10,500 a year.

Enter AI Receptionists

Genni answers your calls 24/7/365:

  • Emergency calls: Answered rather than missed, with what the caller said recorded in their own words
  • Quote requests: Details taken, you call back same day
  • Questions: Common questions answered ("Do you do bathroom installations?" "What areas do you cover?")
  • Booking requests: the caller's details, passed to you to confirm

Cost: £150/month

That is the price of one small job. Not £24,000 a year for a full-time receptionist, not £12,000 for someone part-time. £1,800 a year.

Put your own numbers in. If she catches two or three jobs a month that you would otherwise have missed, she has covered her cost.
