Every tradesperson knows the moment. You are under a sink, up a ladder, elbow-deep in a consumer unit, and your phone rings in the van. You cannot answer. By the time you check it at lunchtime there is a missed call, no voicemail, and a number you do not recognise.
Here is the part that stings: that call was probably work. And by the time you ring back, it is somebody else’s work.
The behaviour behind the number
Two facts decide what a missed call costs you, and neither involves any guesswork about technology:
- Callers with a job in hand do not leave voicemail. The pattern is consistent across every study of consumer call behaviour: reach voicemail, hang up, dial the next business on the list. The job goes to whoever answers second, not whoever rings back at 6pm.
- Trades miss calls exactly when they are earning. A missed call at 11am on a Tuesday is not an interruption you skipped; it is a customer who chose you, called you, and got a ringtone.
Put those together and a missed call is not a delayed conversation. It is a donated job.
The maths, honestly done
Take a plumber on an average £200 job and run the week conservatively:
| Week | Missed calls | Would have booked | Work donated |
|---|---|---|---|
| Cautious view | 3 | 1 in 3 | £200 |
| Realistic view | 6 | 1 in 3 | £400 |
| Busy week | 10 | 1 in 3 | £600 |
At the cautious end, one lost job a week is £800 a month. That is not a marketing number; it is a times-table. Swap in your own average job value and your own honest count of last week’s missed calls, and the sum is yours.
The point is not that every missed call was a job. Some were spam, some were someone’s autocorrect, some would never have booked. The point is that one a week is all it takes for the number to dwarf the cost of having every call answered, which on the UK market starts at £49 a month flat.
Why voicemail does not save you
Voicemail answers the phone in the sense that a mailbox answers mail. The caller hears your greeting, weighs leaving a message against ringing the next result on Google, and mostly chooses the second. Your phone’s missed-call log proves the calls happened. It cannot prove what they were worth, because the ones that were worth something never reached you.
This is also why “missed call alert” services, the ones that text you that a call was missed, do not fix it either. Knowing about the fire does not put it out. The caller needed an answer at 11:47, not a callback at 6:30. See what a missed call service needs to actually do for the full picture.
What actually recovers the money
Only a live answer recovers a live caller, and there are three ways to get one:
- Answer it yourself. Free, and impossible while earning, which is precisely when the calls come.
- A human answering service. Works, at £115–£389 a month with setup fees and contracts. Price comparison on the best UK answering services review.
- An AI receptionist. Answers every call, 24/7, takes the details, and texts you the job. From £49 a month. What that looks like on an actual call: the AI receptionist explained.
Which of those fits is your call. But run your own week through the table above first, because the decision is rarely as close as it feels when you are paying for a service you hope you never needed.
Check it against your own phone
Before you spend anything, open your phone’s call log and count last week’s missed calls during working hours. Ring back the numbers you recognise and ask one question: did you get through to anyone else? You will not enjoy the answers, but you will know your number. Then the only question left is whether a 7-day free trial is worth finding out.
