You were under a kitchen sink when the phone went. You saw the missed call at lunch, rang back at two, and it went to voicemail. You both left it there. Most plumbers write that off as one lost job and move on. It is worth more than that, and it is worth working out exactly how much.

Why callers do not wait

Think about who calls a plumber. Roughly two kinds of people.

The first has an emergency. Water is coming through the ceiling. They do not leave a voicemail, because a voicemail does not stop water. They ring the next plumber on the list, and the next, until someone answers. The first plumber to pick up gets the job. Every time.

The second is planning something: a bathroom, a boiler swap, a new tap. No panic. But they are ringing three firms for quotes anyway, because everyone tells them to. If you are the one who did not answer, you are the one who is not in the running.

Either way, the caller decides in minutes, not days. Ringing back at 6pm is not answering. It is queueing up behind whoever already picked up.

The sum, first pass

Made-up numbers, deliberately. Swap in yours; the sum is the point.

Say you miss 8 calls a week while on the tools.
Say 3 of those were real jobs, not spam or wrong numbers.
Say your average job is worth £280.

3 x £280 = £840 a week.
Around £3,600 a month. Over £43,000 a year.

That number is big enough on its own. But it is still an undercount, for two reasons.

Reason one: customers are not one job

A boiler needs a service every year. A family that liked your work rings you for the bathroom two years later, and gives your number to their neighbour. When you miss the first call, you do not lose one job. You lose the whole thread of work that would have followed it.

Say a kept customer is worth 3 jobs over five years,
plus 1 referral who is worth the same.

One missed first call = up to 6 jobs that never happen,
not 1.

You do not need to believe the exact multiplier. Pick your own from your own books: look at your five best customers and count what they have actually brought you. Then remember that each of them started with one answered call.

Reason two: if you advertise, you paid for the ring

If you run Google ads or Local Services Ads, each call has a price on it before you answer. You paid to make that phone ring. A missed call while running ads is the same pound spent twice: the ad money that bought the call, then the job it should have won. If that is you, check your call reports this week; the waste is usually sitting there in plain sight.

What to actually do about it

Three honest routes, two of which do not involve us.

Route one: the free fixes, today. Set a missed-call auto-text on your business mobile: "Sorry we missed you, we are on a job. Text your postcode and the problem and we will ring you within the hour." Then pick two fixed times a day to return calls, and keep them. Costs nothing. Works if you only miss a couple of calls a week. Falls down on emergencies, because a flooded kitchen picks whoever answers now.

Route two: a person answers. An office person, a partner, or a paid answering service. A human voice beats voicemail, and for message-taking it works. Falls down because taking a message is not booking a job: they cannot sort a burst pipe from a slow drip, quote your call-out rate, or put the job in your diary. The ringing round still lands on you at 7pm.

Route three: an answering system that books. Answers every call day and night, asks the questions you would ask, handles the emergency by your rules, and books the job straight into your diary with a confirmation text to the customer. This is what we build, so read our recommendation knowing that. It earns its keep when the weekly tally says the leak is real, not before.

Our honest advice: if your tally comes out at one or two missed calls a week, take route one and keep your money. If it comes out at eight, the maths above is your answer.

Do this today

  • Turn on a missed-call auto-text. Five minutes, free, and it starts catching callers immediately.
  • Start a one-week tally: every call that rang out while you were working. A note on the van dashboard is enough.
  • At the end of the week, run the sum above with your own numbers. Write the yearly figure down somewhere you will see it.

Want a second pair of eyes on the sum? Bring your week's tally and your average job value. Twenty minutes, and you will leave with your real number and an honest read on whether it is worth fixing, with us or without us.
