Here’s where plumbing businesses quietly lose money every week: not on the tools, not on materials, but on the 30–60 minutes of written admin that happens after every job. The quote description. The follow-up message. The “running late” text. The review request you never quite get around to sending. The complaint you’re not sure how to handle in writing without it escalating.

ChatGPT handles all of it. And for plumbers specifically — who typically work alone, are constantly on the move, and have zero interest in sitting at a desk — it’s one of the most practical tools available. Because it runs on your phone.

Prompt 1 — The Job Quote Description

Describing the scope of a job in writing — clearly, professionally, with enough detail that the customer understands what they’re paying for — takes most plumbers 10–20 minutes per quote. Multiply that by the number of quotes you send per week and you’re looking at a significant chunk of unpaid time.

This prompt does it in under 60 seconds. You speak the job details, ChatGPT writes the professional description.

"Write a professional quote description for a plumbing job with the following details: Job type: [e.g. replace leaking stopcock under kitchen sink]. Property: [e.g. 3-bed semi, domestic]. What’s involved: [e.g. isolate supply, remove old stopcock, fit new quarter-turn valve, test and check for leaks]. Any additional notes: [e.g. customer has asked us to check the pressure while we’re there]. The description should be: professional, clear, jargon-free enough for a homeowner to understand, and specific enough to justify the price. 80–120 words. No waffle."

Prompt 2 — The Running Late Text

It happens on almost every job. You’re held up, a previous job ran over, traffic is a nightmare. You need to let the next customer know — but you’re elbow-deep in someone’s boiler cupboard and the last thing you have time to do is craft a professional message. So you send something rushed and half-apologetic, or you send nothing at all and they’re standing at the door wondering.

This prompt generates a professional, warm delay message in seconds from your phone.

"Write a short, professional text message to send to a customer letting them know I’m running late. Details: Customer name: [their name]. I’m running approximately [X] minutes late. Reason (optional): [e.g. previous job ran over / traffic on the A-road]. I’m still coming today. The message should: apologise briefly, give an updated arrival time if possible, sound professional but human — not corporate. Under 40 words. No emojis."

Prompt 3 — The Complaint Response

A customer gets in touch to say something isn’t right. Whether they have a genuine point or not, how you respond in writing determines whether this stays a manageable conversation or escalates into a negative review. Most plumbers either respond defensively or say nothing and hope it goes away. Neither works.

This prompt writes a calm, professional response that shows you take concerns seriously — without admitting fault you don’t owe.

"Help me respond to a customer complaint for my plumbing business. The customer said: [describe or paste their message]. What actually happened from my side: [explain briefly — e.g. ‘the joint was fine when I left, they may have knocked the pipe’ / ‘I did flag this issue to them at the time’ / ‘this is within normal settling’]. Write a professional, calm reply that: (1) thanks them for letting me know, (2) acknowledges their concern without admitting fault I don’t owe, (3) offers a clear next step — e.g. I’ll come back to have a look, or let’s speak on the phone. Under 80 words. Professional and reassuring."

Prompt 4 — The Google Review Request

Plumbers live and die by their local Google ranking. Reviews are the single biggest factor in whether someone calls you or your competitor. Most happy customers would leave a review if you asked — but the ask feels awkward, especially in a trade where you’re not used to asking for that kind of thing.

This prompt writes a natural, non-pushy review request you can send by text right after a job. It works.

"Write a short, friendly text message I can send to a customer after completing a plumbing job, asking for a Google review. The job was: [briefly describe — e.g. ‘fixed a leak under their kitchen sink’]. The message should: (1) check they’re happy with the work, (2) mention that a quick Google review makes a real difference to a local independent tradesperson, (3) include a natural, non-pushy ask — not salesy, (4) thank them. Under 50 words. Sound like a real person, not a template. I’ll add my Google review link at the end."

Prompt 5 — The Social Media Post

You know you should be posting on Facebook or Instagram. You know potential customers look you up online before calling. But after a day on the tools, writing a social post is the last thing you want to do. So nothing gets posted, your profile goes quiet, and the plumber down the road who posts three times a week picks up the jobs you should have got.

This prompt generates a week’s worth of posts in one go. Five minutes, done.

"Write 3 short Facebook posts for my plumbing business in [location]. Each post should be different in angle: (1) A job completion post — we just finished [describe the job briefly, e.g. ‘a full bathroom suite install in Cheltenham’] — friendly, professional, ends with our area covered. (2) A trust-building post about why customers should use a qualified local plumber rather than whoever’s cheapest — no jargon, plain English. (3) A seasonal/practical tip for homeowners — e.g. what to do if your pipes freeze, how to find your stopcock. All three: under 60 words each. Local, human, no hashtags."

Why These Prompts Work When Others Don’t

Every prompt above is built on the CRAFT Method. When you give ChatGPT a specific role, a clear ask, and the right context about your business, it stops producing generic filler and starts producing output you can actually use. That’s the difference between “we value your feedback” and a message that actually sounds like a tradesperson who cares about their work.
