What does a missed call really cost a building or trades firm?
You cannot answer the phone from the top of a ladder. More than half of callers will not even leave a voicemail, and the work you are chasing is the work paying next month's wages.
The short answer: the call you missed was probably the enquiry you needed. More than half of people will not leave a voicemail if they cannot get through, so a missed call is not a message sitting in your inbox for later. It is silence. And in a trade where cash flow decides who is still standing next year, the enquiries you never hear about are the expensive ones.
Why the phone always rings at the worst moment
Nobody in construction misses calls out of laziness. They miss them because of where the work happens:
- You are on a roof, under a floor, or halfway up a ladder.
- You are on site, and the site is loud.
- You are driving between jobs.
- You are quoting one customer while another is trying to reach you.
- It is 7pm and you are finally eating, and the phone goes again.
The office-hours assumption does not hold either. People ring when they get home from work, which is exactly when you have stopped.
What can honestly be said about the numbers
Be sceptical of the figures the AI industry throws around here. Most of the "you lose X% of jobs to slow replies" claims trace back to software vendors with no method and no sample. Here is what stands up.
| What we can back with a source | Figure | Source |
|---|---|---|
| People who will not leave a voicemail if they cannot get through | 54% | Moneypenny, UK, 2024 |
| People who say unanswered calls are their top phone frustration | 35% | Moneypenny, UK, 2024 |
| People who would go elsewhere after a poor experience on the phone | 38% | Moneypenny, UK, 2024 |
What we will not tell you is that "X% of homeowners immediately ring your competitor", or that tradespeople lose a precise number of hours a week to admin. We looked. There is no honest UK source for either, so we are not going to invent one.
The bit that actually hurts: cash flow
A missed enquiry is not just lost revenue. It is lost revenue in an industry with the thinnest margin for error in the country.
Construction has been the worst-hit UK sector for company insolvencies four years running, with 3,950 construction firms becoming insolvent in the twelve months to November 2025, around 17% of all cases where the industry was recorded. Late payment makes it worse: the government estimates late payments cost the UK economy around £11 billion a year, and close around 38 businesses every single day.
In that context, an enquiry you never answered is not an inconvenience. It is the job that would have covered the month.
And you cannot simply hire your way out
The usual answer is "we will get someone in the office". Good luck. The Construction Industry Training Board reckons UK construction needs an extra 41,200 workers a year between 2026 and 2030, roughly 206,000 people by 2030, just to meet expected demand. The people are not sitting there waiting.
What to do instead
- Find out your real number. Your phone system or your mobile can tell you how many calls went unanswered last month. Most firms are shocked. Start with the truth rather than a vendor's statistic.
- Answer out of hours, not just in them. The enquiry that arrives at 7pm is worth exactly as much as the one at 11am.
- Get the answer right the first time. Half-answering, then promising to "get back to you", is how a keen customer goes cold.
Where Ryku fits
It answers the calls, emails, chats and messages you cannot get to, in your firm's voice, day and night. It knows your services, your areas, your rates and your availability, because it is trained on them. It books the site visit into your diary, and it clears the inbox overnight.
It will not pretend to be an engineer. It does not give structural, safety or building regulations advice, and it does not price a job it has not been told how to price. Anything technical, and anything that sounds urgent, goes straight to a person on your team.
Frequently asked questions
How many calls does a trades business actually miss?
There is no honest national figure, and you should distrust anyone who quotes one. The number that matters is yours, and your phone records have it.
Will customers know they are talking to an AI?
Yes, and they should. It introduces itself. What people care about is that somebody picked up and sorted them out rather than sending them to voicemail.
Can it quote a job?
It can give the rates and prices you have already set, and it can book the site visit that leads to a real quote. It does not invent a price for work it has not seen.
Will it replace my office manager?
No. It covers the calls nobody could reach and the hours you are shut, so your people are not trying to run the phone from a scaffold.
