The office opens the day view at eight.
Three engineers are columns; each job on the column carries the travel buffer the owner set, so a boiler service in one town is followed by a gap before the cylinder replacement in the next.
Overnight a request came in through the website from a customer inside the service area: a photograph of a dripping stopcock, the property type and a preferred morning slot.
The office quotes a first-hour charge and a parts estimate from the price list, sends it, and the customer approves online before nine.
The job moves from quoted to booked and drops into the gap on the second column.
