They Ring. You’re on a Job.
Busy, no-answer, or a dedicated Slotby line. UK voice, not your voicemail.
For heating engineers
The Boiler’s Dead. You’re Already on a Breakdown.
Slotby is an AI receptionist for heating engineers across the UK. No hot water, fault codes, annual services — it picks up, takes the make and the code if they have one, books a slot, and texts the van.
A Worcester 108 is not “someone will call you back”. The script knows the difference.
What the caller hears
Worcester Combi, Flashing 108. Booked for 11am.
House getting cold, kids at home. Voicemail loses that job to the next Gas Safe van on Google.
Northgate Heating · live booking desk
Slotby: Northgate Heating — boilers and heating. Is the heating off?
Caller: Worcester combi. No hot water since this morning.
Slotby: Any fault code on the display?
Caller: It’s flashing 108. The house is getting cold.
Slotby: That’s a circulation fault. I can get an engineer out at 11am tomorrow.
Caller: 11am works. Please book it.
Text to you: Job booked: Worcester combi, fault 108, Birmingham. Tomorrow 11am.
How it works
Fifteen Minutes to Set Up. Then You Forget It’s There.
02
We Book the Diary.
It offers a slot you actually have, and only says booked when the calendar write worked.
03
You Get the Text.
Job, address, time. You don’t log into anything. If it sounds off, we look at the call the same day.
What it will and won’t do
Calm on a Messy Call. Strict on Safety.
It Will
- Breakdowns, no hot water, annual services, landlord checks
- Boiler make and fault code when they can see the display
- A slot that isn’t stacked on the job you’re already on
- A text with the address and the code, once the diary write works
It Won’t
- Dialling 999, or treating a smell of gas as a booking — hang up, they ring 999
- Jobs outside your Gas Safe patch
- Guessing a parts price on a boiler you haven’t opened
- Saying booked if the calendar write failed
