If you fit gas boilers, rewire houses or MOT cars, your phone rings while your hands are full. You're under a bonnet, up a ladder, or holding a live wire, and the call goes to voicemail. The caller, who wanted a job doing today, rings the next number on Google. That's the whole problem, and it's why trades and garages lose work they never even knew was on offer. 85% of people who don't get through the first time don't call back (Dialzara).
An AI front-desk agent fixes this by answering every call in a natural voice, booking the job or the MOT slot, and only bothering you for the calls that actually need you. Here's how to get one live, start to finish. It's less work than you think, and most of it is decisions, not technical setup.
What it'll do once it's running
Before the steps, here's the job it's taking off your hands. An AI front-desk agent for a trades or MOT business will:
- Answer the phone 24/7, including the evening and weekend calls you currently miss
- Quote standard prices ("how much is an MOT", "do you do landlord gas certificates")
- Book jobs and MOT slots straight into your calendar or job-management software
- Take down the details of a new enquiry and text the customer a confirmation
- Pass the call to you when it's something only you can answer
It won't replace your judgement on a tricky diagnosis or a big quote. It'll just stop you losing the routine calls while you work.
Step 1: Sort your number
You've got two choices. Either the agent gets a new phone number that you point your advertising and website at, or, better for most, you port your existing number so the AI answers the line customers already have. Porting takes a few days and means no lost calls and no reprinting the van. If you'd rather test first, start with a new number forwarded from your main line out of hours, then port fully once you trust it.
Decision to make now: do you want the AI answering every call, or only the ones you don't pick up in a few rings? Most garages start with "answer only what I miss" and move to "answer everything" once they see it works.
Step 2: Connect your calendar or booking system
This is the step that turns the agent from an answerphone into a receptionist. Connect it to wherever your jobs live: your calendar, your job-management software (the kind tradespeople use for scheduling and invoicing), or your MOT booking diary. Now when the agent books a 9am MOT, it lands in your actual diary, with the customer's reg and number attached, and you don't retype a thing.
If your booking lives in someone's head or a paper diary, sort that first. The AI can only book into a system that exists.
Step 3: Write down what it should say
The agent needs to know your business, and this is the bit only you can do. Spend half an hour writing down the answers to your most common calls. For a garage that's: MOT price, how long it takes, whether you do repairs, opening hours, where you are. For a trades business: what you cover, your call-out area, rough pricing for standard jobs, whether you do emergencies.
Keep it to the questions you actually get asked. You don't need to script everything. You need to cover the ten things people ring about. Anything outside that, the agent escalates to you.
Step 4: Set your escalation rules
Decide what the AI handles itself and what gets passed straight to a human, you or whoever's free. Good defaults for trades and MOT:
- Handle alone: standard bookings, prices, opening hours, directions, MOT slots
- Escalate to a human: a big or unusual quote, an emergency ("I can smell gas"), an angry customer, anything the agent isn't confident about
The emergency rule matters. A "smell of gas" or "no heating and a newborn in the house" call should reach a person fast, not sit in a booking flow. Set that explicitly.

Step 5: Connect the follow-up
A booked job is worth more if the customer turns up. Set the agent to text a confirmation when it books something, and a reminder before the appointment. For MOTs, a reminder when the next one's due is free repeat business most garages forget to chase. This is usually a toggle, not a project.
Step 6: Test it like a customer
Before you go live, ring your own number and behave like a real caller. Book an MOT. Ask an awkward question. Try to confuse it. Then check the booking actually landed in your diary with the right details. Do this a few times with different scenarios: a simple booking, a price question, a deliberate emergency to check escalation fires. If anything lands wrong, fix the script or the rules and test again. Twenty minutes here saves a week of "why didn't that job show up".
Step 7: Go live, then watch the first week
Switch it on and keep an eye on it for the first week. Listen back to a few calls (the good setups record and summarise them), check the bookings are clean, and tweak the script where the agent fumbled. After a week it'll be running quietly in the background and you'll mostly notice it through the jobs appearing in your diary that you didn't have to answer the phone for.
The mistakes to avoid
Two things trip people up. The first is over-automating, trying to make the AI handle everything including the calls that genuinely need you, then wondering why a customer got a clumsy answer to a complex question. Let it do the routine stuff brilliantly and hand off the rest. The second is no human fallback. If there's no escalation path, an unusual call dead-ends, and that's worse than voicemail. Always have a route to a person.
Set up right, the agent earns its place in a week: it answers the evening calls you used to miss, books the MOTs and the boiler services while you work, and only interrupts you when it should. The phone stops being the thing that costs you jobs and starts being the thing that brings them in. Curious what it costs to run? Our pricing guide has the full breakdown.
Frequently asked questions
How long does it take to set up an AI receptionist for a trades or MOT business? The setup itself is quick, often a day or two of decisions plus a few days to port your number. Most of the work is writing down your common answers and escalation rules, not technical configuration. Many businesses are live within a week.
Can an AI receptionist book MOT slots and jobs into my diary? Yes, as long as it's connected to your calendar or job-management software. A booked MOT lands in your actual diary with the customer's registration and number attached, so there's nothing to retype.
Will the AI handle emergency calls? A properly set-up agent escalates emergencies straight to a human. You set the rules, so calls like "I can smell gas" or "no heating with a newborn in the house" go to a person fast rather than into a booking flow.
Do I need to keep my existing phone number? You can. Porting your existing number means the AI answers the line your customers already have, with no lost calls and no need to reprint the van. You can also start with a new forwarded number to test first.
What happens to calls the AI can't deal with? They escalate to you or whoever's free, based on the rules you set. Always make sure there's a human fallback so unusual calls never dead-end.
