The one stat worth trusting
This niche is full of scary numbers from companies selling answering services, most with no real research behind them. The figure worth anchoring on comes from an actual survey: Moneypenny's Small Business Call Report (2022), which surveyed 300 UK micro-businesses and analysed call data from 10,000 firms.
Two findings matter most for a trade business:
- 33% of small businesses failed to answer incoming calls
- 69% of callers who reach voicemail hang up without leaving a message
- Small firms are 3× more likely than large ones to rely on voicemail
What a missed call actually costs
A missed call isn't a lost message. It's a lost job. To put a number on it, use real call-out fees rather than a vendor's invented figure. Checkatrade's 2026 cost guides put a typical plumber call-out around £40–£60, with the wider market £70–£160 and emergency call-outs £100–£120+. Electrician hourly rates sit around £45–£60, more out of hours.
Work a conservative example. Say you miss 4 calls a day. Not all are jobs, say 1 in 5 turns into real work at an average £150. That's roughly 4 missed jobs a week, about £2,400 a month, ~£28,000 a year, walking to whoever picks up next.
Scale the numbers to your own call volume and ticket size and the point holds: even a low missed-call rate is real money when each job is worth three figures.
The numbers you should ignore
Plenty of figures get repeated across answering-service marketing with no source. Treat these as unproven:
- '£24,000 a year lost to missed calls', traces to AI-vendor press releases, no primary survey
- '62% of inbound calls go unanswered', vendor blogs, no named study; the defensible figure is Moneypenny's 33% failing to answer
- '85% won't leave a voicemail', circulates widely; the sourced UK number is 69%
- '£30bn lost across UK businesses', could not be traced to any primary source
Why you miss calls (and why none of it is fixable by trying harder)
The reasons are structural, not a discipline problem:
- You're on the tools, up a ladder, under a sink, hands full
- Calls land outside 9–5, at lunch, or at the weekend
- Emergency work clusters: a cold snap and every no-heat call comes at once
- There's no one in the office to pick up, and a person can't answer two calls at once
The fix is a callback, not a faster ring
Voicemail loses 69% of callers because it waits for the customer to act. The pattern that recovers those calls is the opposite: ring the customer back automatically, within seconds, before they've dialled the next firm.
That's what an AI receptionist does in callback mode. A missed call triggers an immediate return call, in your firm's voice. That triages the job (no-heat, lock-out, leak), books routine work straight into your diary, and pages you for genuine emergencies. The research on response speed is blunt: faster contact wins far more of the work (Harvard Business Review / Oldroyd, on inbound lead response).
It won't replace you on the job. It stops the calls you can't answer from becoming someone else's job.
