Q3 2026 Field Report
The Missed Call Index — Q3 2026 Edition
A quarterly field report from Whoza on the calls UK trades businesses don't answer, written by Dru McPherson, founder.
Intro: The £8,000 ladder problem
Fifteen years ago I lost an £8,000 boiler install because I was up a ladder in Cheltenham when the phone rang. It went to voicemail. The woman didn't leave a message. They never do. She rang the next plumber on Google, he answered, and he fitted her boiler, her sister's boiler, and her bathroom two years later. I know because he told me, in the pub, with the exact grin you'd expect.
I carried that one for years. Every tradesperson I know has a version of the same story, and we all tell it like it's bad luck. It isn't luck. It's arithmetic. One unanswered call here, two there, and by Christmas you've paid for somebody else's holiday.
So we measured it. This is the first Missed Call Index: what we found, what it costs, and what the small minority who answer everything are doing differently.
Headline findings
1. Missed calls put £2.3bn of UK trades revenue at risk every year
£2.3 billion a year in revenue is at risk across UK trades businesses from unanswered calls. That's not a scare number. It's 885,000 construction businesses each losing, on a deliberately conservative model, about £2,600 a year in jobs that rang out. The full calculation is in "What a missed call costs", and every input is sourced or declared. Argue with any input you like. The answer stays ugly.
2. A third of small businesses fail to answer the phone
A third of UK micro-businesses fail to answer their incoming calls. One in three. That's from Moneypenny's Small Business Call Report, a proper survey of 300 micro-businesses backed by call data from 10,000 firms, not a marketing blog. If you get fifteen calls a week, five of them are ringing into a void.
3. Voicemail loses 69% of callers before the beep
69% of callers who reach voicemail hang up without leaving a message. Seven out of ten people who hit your recorded greeting are gone before the beep. Voicemail isn't a safety net. It's a polite way of telling customers to try your competitor.
4. Small firms lean on voicemail three times as much as big ones — at exactly the wrong hours
Small and micro businesses are three times more likely than large ones to rely on voicemail (Moneypenny). And the phone rings hardest when you're least able to answer it: customers ring when the boiler dies and the fuse box trips, which is mornings, mostly, which is when you're under a floor. Tuesday at 9am is when you're flat out, and it's when Mrs Patterson's boiler gives up. (Whoza platform data on hourly patterns: pending Q3 export, see appendix.)
5. 88% of construction firms don't use AI — and that's the opening
88% of construction firms neither use AI nor plan to, according to the Government's own AI Adoption Research, while 16% of UK businesses overall already use it. That's nearly nine in ten firms in our sector standing still while one in six across the economy moves. The few who answer every call will quietly take the work of everyone who doesn't.
The data by trade
Unanswered rates and peak windows are Whoza platform data (aggregate, anonymised, ~50 active trade businesses). Figures marked [PD] are reserved for the verified Q3 export and stay unpublished until it lands. Revenue-at-risk is modelled per "What a missed call costs", with trade job values from Checkatrade's 2026 cost guides.
| Trade | Unanswered rate | Peak missed-call window | Est. revenue at risk / month | Source |
|---|---|---|---|---|
| Plumber / heating engineer | [PD] | [PD] | ~£217 | Platform data [PD]; £50 avg job (Checkatrade 2026) |
| Electrician | [PD] | [PD] | ~£217 | Platform data [PD]; £50 avg job (Checkatrade 2026) |
| Locksmith | [PD] | [PD] | ~£430 | Platform data [PD]; £100 emergency call-out (Checkatrade 2026) |
| Roofer / builder | [PD] | [PD] | Withheld until export | Platform data [PD] |
| All trades (modelled average) | ~33% (benchmark) | Weekday mornings | ~£217 | Moneypenny; DBT BPE 2025 |
When the phone rings
Customers don't ring when it's convenient for you. They ring when the school run reveals the leak and the commute reveals the "we need someone today." Your busiest earning hours and your busiest ringing hours are the same hours. You can't solder a joint and take a booking at the same time. Something gives, and it's always the phone.
We'll publish the exact hourly and day-of-week pattern with the verified Q3 platform export. For now, the benchmark: small firms lean on voicemail three times as much as large ones, and 69% of callers punished for it hang up.
What a missed call costs — the calculation, step by step
No hand-waving. Every input below is either sourced or labelled as our assumption.
- Businesses. 885,000 SMEs operate in UK construction, the largest sector by business count (Department for Business & Trade, Business Population Estimates 2025).
- Missed calls. A third of small businesses fail to answer incoming calls (Moneypenny). We model a modest 15 inbound calls a week per business, of which a third, five calls, go unanswered. Call volume is a stated modelling assumption, kept deliberately low.
- Conversion. One in five missed calls would have become a paid job. Stated conservative assumption. That's one lost job a week.
- Job value. £50, the midpoint of a typical plumber's call-out fee (£40–£60, Checkatrade cost guides 2026). We use small-job value, not the £200–£600 full-job figures, to stay conservative.
- Per business per year. 1 job × £50 × 52 weeks = £2,600 a year. Call it £217 a month, walking to whoever answered instead.
- National total. £2,600 × 885,000 businesses = £2.3 billion a year.
Change an input and the number moves. Use Checkatrade's full-job average of £150 or more and it triples. We chose the smallest defensible version, because the smallest version is bad enough.
If you'd rather not watch £217 leave the business every month, see how Whoza answers every call.
What the 6% know
The Government's AI Adoption Research (DSIT, fieldwork February–May 2025, 3,500 UK businesses) found 16% of businesses now use AI. One in six. But in construction, 88% neither use it nor plan to. Strip out the planners and the firms actually using AI in construction come out in single figures: roughly six in a hundred, against 43% in information and communication (two in five) and 54% in a March 2026 British Chambers of Commerce member survey of SMEs (more than half).
This isn't a lecture. I was the 94% for most of my working life; I didn't need an app to fit a bathroom. But here's what the 6% have worked out: AI in a trade business isn't robots laying bricks. It's someone answering the phone while you're laying bricks.
Construction sits among the least digitised sectors in Britain on the Government's own numbers. That gap isn't a failure of the trades. It's the biggest competitive opening we've had in twenty years. The plumber who answers every call doesn't need to be cheaper, faster or better. He just needs to pick up. See how Whoza compares to a traditional answering service.

Declared assumptions (ours, not sourced): 15 inbound calls/week; 1-in-5 missed-call-to-job conversion. Both deliberately conservative.
Deliberately excluded: the widely circulated "62% of calls go unanswered" and "85% won't leave voicemail" figures. Neither could be traced to a primary published source, so neither appears in this report.
