AI for the Trades

You didn't get into the trade to sit doing quotes at 10pm. This guide is about using AI to claw back that evening admin — the quotes, the chasing, the scheduling, the marketing — without letting it anywhere near the parts of the job where being wrong gets someone hurt. Plain English, no hype, and the hard limits stated straight.

What "AI" means for a one-van or small firm

In practice it's an assistant you talk to in plain language on your phone — you type or dictate, it writes back. Tools like ChatGPT, Claude or Gemini can draft, summarise, explain and organise text. If you're new to it, start with our Beginner's Guide to ChatGPT; everything below builds on that.

Where it genuinely helps

• Quotes and estimates — the writing, not the pricing. Give it the job, your labour rate and your materials list, and it drafts a clear, professional quote with a proper breakdown and terms. You supply the numbers and check them — it just turns your notes into something you'd be proud to send.
• Chasing and admin. Polite payment reminders, follow-ups on quotes, appointment confirmations, a firm-but-fair letter about a late payer. The messages you keep meaning to send.
• Scheduling, in plain words. "I've got these six jobs this week, two need materials ordered first, one's the other side of town — sort me a sensible order." It's a good planner; you make the final call.
• Marketing you never get to. A Google or Facebook post, a "before and after" caption, a tidy description for your website, a leaflet for a new estate. Reviews replies, too — warm, professional, quick.
• Making sense of the boring stuff. Paste in a supplier's terms, an insurance letter, or a chunk of a spec and ask, "What does this actually mean for me?"
• Job notes and handovers. Dictate a rough site note and have it turned into a clean record or a customer-friendly summary of what you did.

What NOT to trust it with — the part that matters

Here's the line, and it's not fuzzy. AI is for the office, not the calculation and not the compliance. On the job, treat anything it says as unverified until you've confirmed it against the regs, the manufacturer, or your own qualified judgement.

• Technical sizing and calculations. Cable sizes and circuit design, gas pipe sizing, structural loads, boiler and flue specs, fall on a drain. These tools can produce a confident, wrong number. Do the calc yourself, to the standard.
• Anything notifiable or certifiable. Building regulations sign-off, electrical work under the regs, and gas work are legal responsibilities that rest on a competent, registered person — not a chatbot.

Gas work must be done by a Gas Safe registered engineer — legal competence and registration sit with a qualified person, never with an AI tool.

Certain building work needs building-regulations approval and sign-off; that responsibility is a human, competent-person duty — AI can explain the process but cannot discharge it.

• Safety judgements. Whether a job's safe to proceed, whether that wall's load-bearing, whether an old system's fit to reconnect — eyes, experience and the right test kit. Not a phone.
• Final pricing. It can format a quote beautifully and still get the sums wrong. Your margin is your business; check every figure.

A word on tax, records and customer data

If you're VAT-registered, your digital record-keeping and returns must meet HMRC's rules — AI can help you draft and understand, but your figures and submissions are your legal responsibility.

VAT-registered businesses must keep digital records and file under Making Tax Digital — use AI to draft and explain, but the submitted figures are your responsibility.

And mind the data: anything you type goes to the tool's company. Don't paste in customers' full addresses, card details or anything sensitive you wouldn't hand to a stranger. If you hold customer information, you've got data-protection duties — know what a tool does with what you feed it.

A safe first task, tonight

Take the last quote you scribbled on a notepad. Type the bare facts into the assistant — the job, your day rate, the materials and rough prices — and ask: "Turn this into a clear, professional quote with a breakdown and simple terms, in British English." Then check every number and send it.

You'll have a smart-looking quote in two minutes, you'll see exactly how it works, and because you checked the figures, there's no risk. Do that for a week on your quotes and reminders and you'll quickly feel where it saves you real time.

The honest bottom line

For the trades, AI is the office assistant you couldn't afford — clearing the quotes, the chasing, the scheduling and the marketing so your evenings are yours again. It is not a calculator you can trust, not a substitute for the regs, and never the competent person who signs off a job. Keep it firmly in the office, own every number and every certificate yourself, and it'll pay for the time it saves you many times over.
