A plumbing and heating firm in Kent has three engineers and one office manager. The firm missed about four in ten calls, and each call can be worth a 180-pound job. A consultant set up an AI voice agent on the firm's real line, linked to its booking calendar. The setup used a script for the eight most common call reasons and three months of call recordings, so the agent learned real customer phrasing. Booking confirmations go out by text. Any call that mentions no heating, a leak, a smell of gas, or an elderly relative goes straight to a person within one ring. The team tested the agent for two days with difficult test calls before any real call came in.
How it wentAfter 30 days and about 190 calls, the missed-call rate fell from 41% to 6%. The agent booked 58% of all calls with no human help, and it passed 22% to a person by its own flags. Bookings that would have gone to voicemail brought about 2,100 pounds in the month, against a bill of 337.90 pounds. On day nine, a distressed elderly caller got polite questions instead of a fast transfer. She hung up and called back annoyed, and the trigger words were fixed after that call.
