That's around £10,000 for the average phone-reliant business — money that rings out after hours, on the job and at peak times. Here's how the numbers stack up, and how to work out your own.
Missed calls are the most expensive problem no one measures. A plumber up a ladder, a salon owner mid-blow-dry, a receptionist with three lines ringing — each missed call is usually a customer already phoning a competitor. It never shows up in the accounts, because you can't see the jobs you never heard about.
No smoke and mirrors. This is a model built on cautious assumptions — so you can check every step and decide for yourself.
We started with a single phone-reliant small business and asked a simple question: how many genuine new-customer calls slip through in a normal week — the after-hours ones, the ones that ring out mid-job, the ones that hang up at peak time?
Four a week is a low estimate for most trades. £50 is deliberately cautious — a fraction of what a new patient, a legal matter or a boiler job is really worth. Even so, it adds up to £10,000 a year walking out of the average small business.
The ONS counts around 5.5 million private-sector businesses in the UK, almost all of them small. We modelled a conservative subset of 2 million that live or die by the phone — trades, clinics, salons, garages, agents and the like.
These are cautious inputs. For higher-value trades the per-business figure is many times larger — which is why we treat £20 billion as a floor, not a ceiling.
The average hides big differences. Using the same "just a few calls a week" idea with realistic customer values:
| Business | New customer worth | 3 missed calls a week ≈ |
|---|---|---|
| Salon | £45 | £7,000 a year |
| Tradesperson | £180 | £28,000 a year |
| Car garage | £220 | £34,000 a year |
| Dental practice | £300+ | £46,000+ a year |
| Law firm | £500+ | £78,000+ a year |
Illustrative, based on typical new-customer values × 3 missed calls a week × 52 weeks. Your own figures will differ — that's exactly what the calculator is for.
The national figure is a model. Your figure is real — and you can have it in 30 seconds. Move four sliders and see it for yourself.
