AI for tradespeople: win the job while your hands are full
In a trade business, the first sensible reply often wins the job. The trouble is that enquiries arrive while you are under a sink, up a ladder or driving between visits, and they come in on WhatsApp, Facebook, Instagram and email at once. An AI agent can reply in minutes, ask for the address and a photo, and hand you a complete job to price. It must never diagnose a fault or promise a price it cannot stand behind. This guide covers the whole business, not one app, and the safety rules that matter when gas, water and electricity are involved.
What customers ask
These are the messages plumbers, electricians, cleaners, handymen and installers get most.
- My boiler has stopped working. Can someone come today?
- Do you cover my postcode?
- How much is a deep clean for a two-bed flat?
- Can you send a quote if I send photos?
- What time will the engineer arrive?
- Are you on Checkatrade or similar, and are you insured?
- Can you fit a socket in the garden?
Some of these have a fixed answer: which areas you cover, your call-out charge, whether you are insured, your published prices for standard jobs. Most need information before anyone can answer: the address, what is wrong, how old the boiler is, a photo. Collecting that is slow, repetitive work, and it is exactly what an agent does well.
A few messages are not enquiries at all but emergencies, such as a smell of gas, water coming through a ceiling or sparks from a socket. The agent's first job with those is safety advice from your notes and an instant alert to you.
An example conversation
This illustration shows a full conversation on WhatsApp. Names and details are examples.
| Who | Message |
|---|---|
| Chris | Hi, my boiler has stopped working, no hot water. Can someone come today? |
| AI agent | Sorry to hear that, Chris. Could you send your postcode, the make of the boiler if you can see it, and a photo of any error code on the display? |
| Chris | LS6 2AB. It's a Worcester, says EA 227 [photo] |
| AI agent | Thanks. LS6 is in our area. Our call-out charge is £65, which includes the first half hour. I've sent your details to Mark, who will message you shortly with a time. |
| → Passed to Mark: boiler, no hot water, LS6 2AB, Worcester, error EA 227, photo attached | |
| Mark (staff) | Hi Chris, Mark here. I can be with you between 3 and 4 today. Does that work? |
| Chris | Perfect, thanks! |
Outcome: a booked job from a message that arrived while Mark was on another visit. The agent gave the area and call-out charge from its notes and collected everything Mark needed. It never guessed what the error code meant.
A second example: an emergency
This illustration shows the agent putting safety first and getting a person involved at once. Names and details are examples.
| Who | Message |
|---|---|
| Ruth | I can smell gas in my kitchen, can you come? |
| AI agent | Please leave the property now, don't use switches or flames, and call the National Gas Emergency number on 0800 111 999. I've alerted Mark straight away. |
| → Passed to Mark, marked urgent | |
| Mark (staff) | Ruth, Mark here. Please call the emergency line first. Once they've made it safe, I can come and look at the appliance. |
The agent gave the safety line from the owner's note, word for word, and handed over. It did not try to work out how serious the leak was.
What the agent handles, and what goes to your team
The agent can handle:
- Which areas you cover, your hours and your call-out charge
- Fixed prices you publish, such as a standard clean or a boiler service
- Collecting the address, the problem, photos and a good time to visit
- Confirming visits and arrival windows with customers who booked, once you have set the time
- Proof of insurance and accreditations, from your notes
It should pass these to a person, and then stay out of the chat:
- Quotes for anything that needs a look, and every diagnosis
- Emergencies: gas, water leaks, electrical danger, no heating for vulnerable people
- Complaints, snagging and disputes about a bill
- Anything a customer asks about doing the work themselves
The rules that matter in the trades
- No diagnosis in the chat. "That error usually means the pump" sounds helpful and can be wrong. Only the person who sees the job says what is wrong.
- No DIY safety advice beyond your emergency line. The agent never tells someone how to reset a fuse box or bleed a boiler.
- Prices are published or they come from you. The agent quotes only the fixed prices in your note.
- Arrival times come from your diary. The agent confirms a time only once you or your diary have set it.
Write the emergency reply into your note word for word, with the right number for your country and trade. The agent should send exactly that, every time.
Which channels to connect
| Channel | Who uses it | Good to know |
|---|---|---|
| Most customers, especially for photos and arrival times | Use the number on your van and invoices | |
| Messenger | Local people who find you through Facebook groups and pages | Good for "do you cover my area?" questions |
| Customers looking at photos of your finished work | More common for kitchens, bathrooms and landscaping | |
| Landlords, letting agents and commercial clients | One email to one person, with job sheets attached |
Start with the account where most enquiries land, usually WhatsApp. You connect it by scanning a QR code with the work phone, and replies to customers who message you are what it is built for.
The notes to give your agent
Here is an example note for a small plumbing and heating business. Names and details are examples.
You answer messages for Hartley Plumbing & Heating on WhatsApp,
Messenger and email. We cover Leeds postcodes LS1 to LS17.
Hours: Mon to Fri 8am to 6pm, Sat 9am to 1pm.
Call-out charge: £65 including the first 30 minutes, then £45 an hour.
Fixed prices: annual boiler service £95. Fitting a tap from £80.
We are Gas Safe registered and fully insured; send the registration
number 000000 if asked.
For a new job, collect: postcode, the problem, the make of any
appliance, a photo, and the best times to visit. Then hand to Mark.
Never diagnose a fault or say what an error code means.
Never quote for anything not in the fixed prices above.
Only confirm a visit time once Mark has set it.
If someone mentions a smell of gas, reply exactly: "Please leave the
property now, don't use switches or flames, and call the National Gas
Emergency number on 0800 111 999. I've alerted Mark straight away."
Then hand to Mark and mark it urgent. Do the same for water through
a ceiling or sparks, using the advice to turn off the water or power
at the mains only if it is safe to do so.
Complaints and bills go to Mark. Sign off as "Hartley Plumbing".Wording that works
| Situation | Weaker reply | Better reply |
|---|---|---|
| "How much to fix my boiler?" | "Usually around £150." | "Our call-out is £65 including the first half hour. Could you send a photo of the error code so Mark can tell you more?" |
| "What does error EA 227 mean?" | "That's the ignition, easy fix." | "Mark will look at that for you. I've sent him your photo." |
| "What time will you get here?" | "Sometime this afternoon." | "Mark will message you with a time shortly." |
| Enquiry on a Sunday | No reply until Monday | "We're closed today. I've taken your details and Mark will reply first thing Monday. If it's an emergency, here is what to do..." |
Set it up step by step
- Write down your area, hours, call-out charge and any fixed prices.
- List the details you always need for a new job: postcode, problem, appliance, photo, times.
- Write the emergency reply word for word, with the right numbers.
- Add Spaces to the AI agent you already use. The agents page has the steps for Claude, ChatGPT, Cursor and others; you sign in through your browser and approve the connection. Chat apps such as Claude or ChatGPT act when you ask them in a chat, so for replies around the clock use an always-on agent such as Claude Code, Codex, OpenClaw or Hermes.
- Connect WhatsApp by scanning the QR code with the work phone, then add Messenger or email if enquiries come there too.
- Test with a friend: a normal enquiry, a price question, an emergency and a complaint.
- Check hand-overs between jobs, not only at the end of the day.
Common mistakes to avoid
- Letting the agent quote "ballpark" prices for jobs it cannot see. Customers remember the lowest number.
- Forgetting holidays and fully booked weeks. Tell the agent when you have no space, so it does not imply a quick visit.
- Not checking hand-overs during the day. A collected job that waits until evening loses its head start.
- Messaging past customers about offers. Reminders are for people who booked, such as an annual service they asked to be reminded about.
What if...
| If this happens | What the agent should do |
|---|---|
| The postcode is outside your area | Say politely that you do not cover it. |
| A customer asks how to fix it themselves | Say a person will advise, and hand over. No DIY instructions. |
| A landlord reports a job for a tenant | Collect the address, tenant contact and problem, and hand over. |
| A customer is unhappy with finished work | Apologise once, say you will reply personally, and hand over. |
| The agent is not sure whether it is an emergency | Treat it as one: send the safety reply and hand over. |
Checklist before you go live
- Your area, hours and call-out charge in the note match your website and van.
- The emergency reply is written word for word and tested.
- The agent asks for every detail you need, in one message.
- You know how to pause all sending if you are away: Settings, then Pause everything.
Where to start
Start with WhatsApp and new job enquiries. Keep diagnoses, quotes and emergencies with you, and check hand-overs between visits for the first fortnight.
Once it works, add arrival-time confirmations for booked jobs and connect the next channel. While you build trust, ask your AI agent to hold replies as drafts, and nothing goes out until you approve it.

FAQ
Can the agent give quotes?
Only the fixed prices you publish, such as a standard service. For anything that needs a look, it collects photos and details and you send the quote. That protects you from a number you cannot stand behind.
Can it book jobs into my diary?
Only if your AI agent can reach your diary or job tool through its own connection. Spaces handles the messages, not calendars. Without that, the agent collects good times and you confirm.
What about emergencies at night?
The agent sends the safety reply from your note and alerts you, whatever the time. For replies around the clock you need an always-on agent rather than a chat app you open yourself.
Can customers send photos and videos?
Yes. Your agent can download attachments from the chat, so a photo of the fault reaches you with the rest of the job details.
Can I message old customers about their annual service?
If they asked to be reminded, yes. Sending service offers to everyone who ever contacted you is a campaign, and that is not what Spaces is for.
Will it work on my personal WhatsApp?
It works with the WhatsApp number you connect, including a personal one, but read the caveat at the top of this page first. WhatsApp restricts automation, and Spaces lowers the risk without removing it.
What if I am on a job and the agent hands me a chat?
The customer stays in the same chat and the agent stops replying there. Answer when you are free, and hand it back to the agent if you want it to carry on.
