The Problem

6–8 Missed Calls Every Working Day

Crestline Plumbing is a two-person operation run by brothers Tom and Dave Okafor in Bristol. Like most sole traders and small tradespeople, they cannot answer the phone while under a sink or on a job site — which is most of the working day.

Tom estimated they were missing 6–8 calls daily. Some callers left a voicemail; most did not. By the time Tom returned calls in the evening, the customer had already found someone else. The lost work wasn't just the immediate job — it was the repeat business and referrals that typically follow a successful first visit.

The Solution

Instant SMS Response That Collects Job Details Automatically

Engium connected to Crestline's business mobile number. Any missed call or incoming text triggers an immediate SMS response: a brief, professional message explaining they're currently on a job and collecting the caller's availability, job type, and address via a short conversational sequence.

Tom receives a structured job summary — what's needed, where, and when the customer is available — delivered to his phone within minutes of the initial contact. He reviews it between jobs and confirms via a templated reply that Engium sends on his behalf.

Every missed call now becomes a lead with job details collected — not a lost customer.

The Results

27% More Jobs, Zero Missed Leads

In the two months following setup, Crestline booked 27% more jobs per month from the same incoming call volume. The improvement came entirely from capturing leads that would previously have gone cold. Tom's evening callback time dropped from 90 minutes to under 20 minutes, because callers now arrive pre-qualified with their details already recorded.

Tom also used the job summary data to notice that 40% of enquiries were for boiler servicing — information he used to create a targeted leaflet for the following autumn.
