What a missed call costs a UK trade

The same survey estimates that UK small and medium-sized businesses lose about £3.7 billion a year because they can't always answer the phone. The exact modelled total is £3.67 billion, or about £71 million a week.

Broken down by size, the figures are:

In the same survey, 67% of small businesses said that on an average day they miss at least one call they believe loses them business.

How the figures were worked out

• Censuswide surveyed 1,500 decision makers at UK businesses with fewer than 250 employees, between 23 and 28 September 2026.
• Owners were asked how much revenue they had lost to missed calls so far this year. Each answer band was valued at its midpoint, "don't know" answers were left out and nine months were scaled up to a full year.
• Business numbers and turnover come from the Department for Business and Trade's Business Population Estimates 2025, as the survey's note states.

These are owners' own estimates, not measured losses, so treat the figure as a guide. The method is published in full, and you can read it and judge for yourself.

In a 2026 survey of 2,000 UK adults, published alongside it, carried out between 23 and 25 September 2026, 75% said they would give a business three call attempts before giving up on it.

The same survey found that 58% would tell friends and family to avoid a business that didn't pick up. For a trade that relies on word of mouth, that matters as much as the job itself.

So a missed call isn't always lost straight away. But a caller who gets no answer may well ring the next name on the list, and someone with a burst pipe may not wait for a second try.

Count only the calls that matter for this sum: new customers asking for work. Existing customers and suppliers usually ring back. Then use this:

Cost of one missed new-enquiry call = average job value × the share of new enquiries that turn into work.

Worked example (example figures, not data)

These numbers are made up to show the sum. They aren't averages for any trade, and they aren't Ringzel customer data. Swap in your own, whether you're a plumber, electrician or heating engineer.

1. 1One missed new-enquiry call: £200 × 25% = £50.
2. 2One week: 2 calls × £50 = £100.
3. 3One year: £100 × 48 weeks = £4,800.

Our missed call calculator uses the same sum over a full 52 weeks and starts from different example figures (10 calls a week, 30% won, a £250 job, so £39,000 a year), so put in your own numbers rather than comparing the two.

Change one number and the answer moves a lot. Using the same example figures, missing five new enquiries a week instead of two makes it £12,000 a year. A £1,000 job, such as a larger install, makes each missed call worth £250 at the same 1 in 4.

Where to find your own numbers

• Missed calls: your phone's call log, or your provider's online account, for two normal weeks.
• New enquiries: check which of those numbers aren't already in your contacts or job list.
• How many turn into work: out of your last 20 new enquiries that you did answer, how many booked?
• Job value: your average invoice over the last few months.

If you'd rather work it through by hand, our guide to whether an AI receptionist is worth it uses the same method.

The sum above only counts the first job. In practice a new customer can also bring:

• Repeat work, like an annual service or the next room.
• Referrals. The finding that 58% would warn friends off a business that didn't answer cuts the other way too.
• Reviews, which help the next customer choose you.

If you advertise with Google Local Services Ads, Google says in its own help pages that "Missed calls may negatively affect your responsiveness", which is one of the factors in how its ads are ranked (Google Local Services Help). That statement covers Local Services Ads only. Google doesn't say this about ordinary search results.

We've left these out of the worked example because they're hard to put a number on. Your real cost is probably higher than the sum shows, not lower.

You don't need to answer every call yourself. You need every new enquiry to land somewhere useful. The main options are:

• Call back fast. Most callers give you more than one try, but not many.
• A voicemail greeting that asks for name, number and the job, and says when you'll ring back.
• Forwarding calls you can't take to someone else. Our guide to forwarding calls in the UK has the codes for the main networks.
• A human answering service or an AI receptionist that answers in your business name and passes on the details. Our comparison of AI receptionists and answering services sets out when each one fits.

Our guide on how to stop missing business calls goes through each one, starting with the fixes that cost nothing.

Ringzel is an AI receptionist for small businesses of every type, from trades to clinics and shops (not RingCentral). It answers the calls you can't take and sends you the details. Plans cost £99, £179 or £299 a month, as shown on our pricing page. If your own sum comes out well above that, it's worth a look. If it doesn't, the free fixes above are the place to start.
