You have just finished looking at a job. The customer wants a quote by tomorrow, it is nearly six, and you still have paperwork from the last two jobs sitting in the van. The work itself was the easy part of your day.
If you are a plumber, electrician, builder, or any trade where the real skill happens with your hands, the writing side of the business is pure overhead. Quotes, follow-ups, job ads, explaining to a customer why the “small leak” is actually a rotten joist.
AI can take most of that typing off your plate. The tools — ChatGPT, Claude, Gemini, and others — work like a very fast office assistant: you tell them what happened in plain speech, they turn it into something written. Here is how that looks across a normal week, starting with the big one.
Quotes from the van, by voice
Say you are a plumber and you have just walked a bathroom refit. Instead of trying to remember everything at your desk tonight, sit in the van and talk into your phone for two minutes. Most AI apps have a microphone button that turns your speech into text — just tap it and ramble:
“Bathroom refit, upstairs. Strip out old suite, customer supplying new bath and basin, I supply the toilet. New pipework to the basin, maybe three meters of copper. Retile around the bath, about four square meters. Two days with my apprentice. Usual day rate plus materials, tiles are extra if they pick the fancy ones.”
Then ask:
“Turn my notes above into a clear written quote for a customer. Plain English, itemized, with a section for what’s included and what’s not. Leave the prices as [PRICE] so I can fill them in.”
You get back a clean, professional-looking quote while you are still parked outside the job. Now the important part: you check every number. Quantities, days, prices, what is included — the AI writes the words, but the figures are yours, and it will happily invent a plausible-sounding figure if you leave a gap. Leaving prices as blanks to fill in, like in the example above, is the safest habit.
Between jobs: follow-ups that actually get sent
Every trade knows the quote that died in silence — not because you were expensive, but because nobody nudged. Following up feels awkward, so it does not happen.
Make it a red-light task. Waiting outside the merchant’s, phone out:
“Write a short, friendly follow-up text to a customer I quoted last week for a fuse board replacement. No pressure, just checking if they have questions and mentioning I have a slot open the week after next.”
Ten seconds to read, one tap to send. Do this for every quote over a week old and you will win jobs you would otherwise have quietly lost.
Explaining the work in plain terms
You know why the whole circuit needs rewiring. The customer heard “money” and stopped listening. When a customer understands the why, they say yes faster and complain less later.
Tell the AI what you found and who you are talking to:
“I’m an electrician. Explain to a homeowner, in plain, friendly language, why a fuse board from the 1980s with no RCD protection should be replaced. Short — five or six sentences — honest about safety without scaring them.”
Read the result with your professional hat on. If it overstates or understates the risk, fix it — you are the qualified one, and anything that touches safety or regulations gets checked by you, not trusted to a chatbot. But as a translator from trade-speak to customer-speak, it is genuinely good.
Writing the job ad for an apprentice
Say you are a builder and finally busy enough to take someone on. Job ads are their own strange language, and a bad one attracts nobody.
Give the AI the real picture:
“Write a job ad for a first-year carpentry apprentice at a small building firm. Two-person company, mostly house extensions and lofts. We want someone reliable and keen, no experience needed, must be able to get to sites locally. Friendly tone, no corporate buzzwords.”
You will get something readable that sounds like a real firm rather than a recruitment agency. Add the true details — pay, hours, how to apply — yourself. Never let the AI fill in things like salary or qualification requirements on its own; it does not know your business and will guess.
End of week: turn the job into tomorrow’s marketing
Finished a nice loft conversion? While it is fresh, voice-note what you did and ask for a short post for your Facebook page or Google profile: what the job was, one problem you solved, one line inviting inquiries. Before-and-after photos plus three honest sentences beats any slogan. Ask the customer before posting photos of their home.
The one rule that covers everything
AI is a confident writer and an unreliable witness. It does not know your prices, your lead times, your regs, or what you actually saw under that floor — and when it does not know, it sometimes makes something up rather than staying quiet. So the deal is simple: it drafts, you verify. Every number, every date, every claim about materials or safety passes through you before it reaches a customer.
That still leaves it doing the part of your evening you hate most.
Try this today
Next job you price up, do the two-minute version: sit in the van, voice-note the walkthrough into ChatGPT, Claude, or Gemini, and ask it to turn your notes into an itemized quote with the prices left blank. Fill in the numbers, send it tonight instead of tomorrow. Being the first quote in the customer’s inbox wins more work than being the cheapest one.
