How much do missed calls cost a trade business?

Last updated: 24 July 2026By: Jamie, founder of TradeSiteHQReading time: 4 min

More than any other single leak in the business. Worked example: a plumber missing 5 calls a week, at a £340 average job and a 40% win rate on answered calls, loses roughly £2,950 a month — about £35,000 a year — to calls that rang out while they were on the tools. The maths for your trade is below, along with the five ways to stop it, compared honestly.

62%

of calls to small trade businesses go unanswered

85%

of missed callers won't leave a voicemail — they ring the next name on Google

78%

of customers hire the first business that responds

Figures from industry call-handling studies; they match what TradeSiteHQ's own website audits of UK trade businesses keep finding.

The maths by trade

Lost revenue = missed calls per month × average job value × your win rate on calls you do answer. Using typical UK average job values and the same 5 missed calls a week (≈22/month) at a 40% win rate:

TradeTypical average jobLost per monthLost per year
Electrician£280~£2,460~£29,500
Plumber / heating£340~£2,990~£35,900
Roofer£1,200~£10,560~£126,700
Builder (small works)£2,500~£22,000~£264,000

Your numbers will differ — fewer missed calls, different job sizes — but even at half these volumes the loss dwarfs what any website or phone system costs. Not every missed call is a new job (some are suppliers or existing customers), which is why the formula only counts them at your win rate.

Why trades miss so many calls

Because you're working. Under a sink, up a ladder, on a saw — precisely the hours (8am–5pm) when customers ring. It isn't a discipline problem and answering-your-phone advice doesn't survive contact with a Tuesday. The fix has to work without you touching the phone.

The five ways to stop the leak — compared

OptionTypical UK costDoes it save the job?
Do nothing / voicemail£0Rarely — 85% of missed callers won't leave a message
Answer everything yourself"Free"Only by interrupting paid work; not sustainable solo
Answering service£50–£200+/monthPartly — a human answers, but the message still waits for you and per-call fees stack up
Office help / family on phones£1,200+/month part-timeYes, at the highest cost — suits 3+ van firms
Missed-call text-backStandalone tools vary; included in some website subscriptions (TradeSiteHQ: within £149/month)Mostly — caller gets an instant SMS, replies with the job, you answer when hands are free

How missed-call text-back works

  1. A customer rings your business number and you can't answer.
  2. Within seconds they get a text from your number: "Sorry I missed you — what needs doing?"
  3. They reply by text with the job (85% who won't leave a voicemail will happily text). You respond when your hands are free — the enquiry never reaches the next name on Google.

The customer installs nothing and every exchange is logged, so no enquiry lives only in your memory. It's the only option on the table that responds in seconds, at 2am or mid-boiler-swap, for no per-call fee.

Frequently asked questions

What is missed-call text-back?

An automatic SMS sent to any caller you don't answer, within seconds, from your own business number — turning a lost call into a text conversation you pick up when free.

Won't customers just leave a voicemail?

Mostly no — around 85% won't. Voicemail is a record of the customers you already lost.

Is an answering service better?

Different tool: humans answering suits complex, high-volume enquiries but costs per call and the message still waits for you. Text-back is instant and free per call; many trades need only that.

How fast do you need to respond to an enquiry?

Within minutes — 78% of customers hire whoever responds first, and lead-response research puts a 5-minute reply at roughly nine times the conversion of a 30-minute one. On the tools, only automation responds that fast.
