Missed calls2 min read

The weeks your phone volume doubles

Every trade has two or three weeks a year when demand arrives all at once. They are entirely predictable, and almost nobody staffs for them.

Published 10 June 2026 · Updated 15 August 2026

Seasonal spikes are unusual among business problems in that you know the date in advance. The first cold snap, the January rush, the morning after a storm.

They are also the weeks where a missed call costs most, because everybody in your trade is equally overwhelmed and the customer simply takes whoever answers.

The spikes worth planning for

These are the reliable ones across UK trades and services. Yours may differ, but the shape does not.

First sustained cold week, usually late October or November: heating, plumbing, boiler replacement
The morning after high winds: roofing, tree surgery, glazing, fencing
First working week of January: gyms, family law, weight management, tutoring
Second half of January: accountants and anything touching self assessment
March and the first warm weekend: landscaping, gardening, driveways, window cleaning
July and August: pest control, particularly wasps
September: nurseries, tutoring, driving schools
November and December: restaurants, spas, salons, voucher sales
Late December to Valentine's Day: wedding venues, photographers, jewellers

Why the spike is worse than the volume suggests

Calls do not arrive evenly across a busy week, they arrive in clusters. The morning after a storm produces most of a roofer's monthly enquiries in about four hours.

A single phone line handles one of those at a time. Even with three people answering, a four hour cluster of two hundred calls cannot be absorbed, and the callers who get an engaged tone do not ring back.

Why hiring does not solve it

You cannot recruit for a week. Temporary staff need training on your business precisely when nobody has time to train anybody, and by the time they are useful the spike has passed.

This is why most businesses simply accept the loss, and why the loss is repeated every year at the same time.

What does work

Capacity that does not need staffing. Software answers a hundred simultaneous calls as easily as one, which is the only property that actually matches the shape of the problem.

Beyond that, prepare the script before the season rather than during it. A heating engineer should have the no heat triage questions loaded in October, not in the second week of the cold snap.

Turn the spike into a pipeline

Not everybody who rings during a spike needs serving that day. Many will accept an appointment later that week if somebody speaks to them and books it.

The businesses that come out of a spike best are not the ones who did the most work that week. They are the ones who captured the enquiries and spread them across the following month.

Questions people ask

Should we take on more work than we can deliver?

No, but you should capture the enquiry and be honest about timescales. A customer told they can be seen on Thursday usually waits. A customer who reaches nobody does not.

Can we just extend our hours during peaks?

It helps and it is worth doing. It does not solve simultaneity, which is the actual constraint during a cluster.
