Missed Call Recovery

Why do gas engineers miss boiler enquiries (and how do you fix it)?

6 min read

Most Gas Safe registered engineers in the UK miss more boiler enquiries than they win. The peak season runs October to February, the calls cluster between 07:00 and 09:00 and again at 17:00 to 20:00, and that is exactly when you are either driving between jobs or elbow-deep in a combi swap. This article explains why the leak happens and how to plug it without hiring an office.

When do gas engineers receive most boiler enquiries?

Two peaks. The morning rush (07:00 to 09:00) when a homeowner wakes to no hot water and starts ringing engineers before work. The evening rush (17:00 to 20:00) when they get home, find the heating still off, and try again. Around 75% of boiler-replacement enquiries happen in those windows. Both are the worst times to be available — you are commuting, on a job, or with family.

Why is voicemail the wrong fallback for a gas engineer?

UK homeowners with no heating in February do not leave voicemails. They hang up and dial the next gas engineer on Google within 30 seconds. The Yell.com effect: by the time you check your phone at lunch, three competitors have already booked their afternoon survey.

How much revenue does a missed boiler enquiry actually represent?

An average UK boiler installation runs £2,400 to £3,800 supply-and-fit, with margins of £400 to £900 per job. Miss six enquiries a week during the winter peak, convert nothing from voicemail, and you have lost roughly £15,000 in profit between October and March. For a two-engineer firm, the leak doubles.

What does a 60-second AI response do for a gas engineer?

The Keystone OS picks up calls in your company name, asks the right qualifying questions (boiler age, fuel type, postcode, urgency, landlord vs homeowner), offers a live survey slot, and sends an SMS confirmation before the homeowner rings the next engineer. Compliance-sensitive enquiries (suspected leak, CO concern) trigger an immediate human handover with full context.

Does this work for landlord gas safety certificate enquiries too?

Yes, particularly well. Landlords book CP12 inspections in batches and value the speed and professionalism of the response. The AI can capture portfolio size, multiple addresses, and recurring renewal dates, then book a route-optimised inspection day automatically.

Frequently asked questions

Why do gas engineers miss so many boiler enquiries?

Because peak enquiry windows (07:00-09:00 and 17:00-20:00) overlap exactly with when engineers are driving between jobs or finishing on site. UK homeowners with no heating do not leave voicemails — they ring the next engineer.

How much revenue does a missed boiler enquiry cost?

Around £400 to £900 in lost profit per missed installation enquiry. A typical one-man firm misses 6 to 10 enquiries a week in winter, costing £15,000+ in profit between October and March.

Can AI handle gas-safety-sensitive enquiries safely?

Yes. The Keystone OS triages standard enquiries and books surveys, but immediately routes any safety-critical issue (suspected leak, CO concern) to you with full context.

Does it work for landlord CP12 batch bookings?

Particularly well. The AI captures portfolio size, addresses, and renewal dates, then books a route-optimised inspection day for you.
