How Much Does a Missed Call Actually Cost an Irish Plumber?

There's no invoice for a missed call. No line item in your accounts. Nothing that shows up anywhere — which is exactly why most plumbers underestimate how much it's really costing them.

You're under a sink, up a ladder, or driving between jobs, and the phone rings. You can't get to it in time. No big deal, right? Except that call doesn't go to voicemail and wait patiently for you to call back — in most cases, it just goes straight to the next plumber on Google.

The 27% problem

Industry-wide, roughly 27% of inbound calls to busy trades businesses go unanswered. That's not a reflection of anyone doing a bad job — it's just the nature of the work. You can't run a drill and answer a phone at the same time, and most one- or two-person operations don't have a dedicated person sitting by the phone all day.

Work out your own number

Instead of relying on an industry average, it's more useful to work out roughly what it's costing your business specifically. The formula is simple:

That weekly figure — €297 — happens to land right around what a fully installed AI receptionist costs per month. Recover just one of those calls a week, and the system has already paid for itself.

Why it's worse than the number suggests

The direct lost job is only part of it. A few things compound the real cost:

• Referrals: a happy customer typically refers a few more jobs your way over time. A customer you never got doesn't refer anyone.
• Reviews: the business that answers the phone is the one that gets the 5-star Google review after the job's done — not you.
• Repeat business: that customer's boiler will need servicing again next year. If someone else answered this time, they'll probably call that same business again.

The actual fix

None of this requires answering every call yourself. It just requires something answering every call — qualifying the job, taking the details, and getting it booked, even while you're mid-job or after hours. That's the entire premise behind FlashBooked's AI receptionist for plumbers: it picks up when you can't, so the calls you're already paying to generate (through ads, Google, word of mouth) don't quietly leak away.
