Can ChatGPT Write a Plumber's Quote? Yes. Here Are the Rules
Short answer: yes. ChatGPT or a similar tool can turn rough site notes into a tidy itemised quote in a couple of minutes. It can't price the job. It doesn't know your labour rate, your supplier prices or what's behind the wall. The AI writes the words. You set the price.
That's the main rule. The rest is method.
Nobody starts a trade to write quotes at 9pm. If that's your evening, this is for you.
Why do it
Quotes are evening work. Kitchen table, after a full day. The typing and wording are the slow bit. That's what AI is good at.
The judgement is yours. What the job needs. What you charge. That doesn't change. AI is good at drafting and structuring text, and bad at measurements and site conditions. Use it for the paperwork, not the thinking.
I set up AI for businesses. The pattern that works is simple: you give it rough notes, it drafts, you check and send.
The method
- Take notes on site. Bullets. A voice note in the van. Photos. No full sentences needed.
- Paste them in with your own prices. Never ask it to guess prices.
- Ask for the customer version. Plain English, clear scope, clear total.
- Check every line. Scope, materials, labour, VAT, exclusions, how long the quote is valid.
- Send it from your own email or phone. Not from the AI tool.
A prompt to copy
Change the bits in brackets:
I'm a UK plumber. I've surveyed a [3-bed semi]. Scope: [replace the combi boiler like for like, new filter, flush the system, move the condensate pipe]. My labour is [£X per day, 2 days]. Materials: [boiler £X, filter £X, fittings and sundries £X]. Write a clear itemised quote for the homeowner with labour, materials and a total. Add short exclusions (anything not listed is not included) and say the quote is valid for [30] days. Under 300 words. Friendly, plain English. Do not add any prices I haven't given you.
That last line matters. Without it, AI sometimes fills gaps with numbers that look sensible and are wrong.
Check before you send
- Every price matches what you gave it. Add the total up yourself.
- Nothing promised that you didn't mean. AI loves friendly extras like "aftercare included" or "all tidying up included". Cut anything you won't honour.
- Exclusions are clear. Making good, redecorating, hidden faults, asbestos, anything you'd charge extra for.
- No technical or safety claims you can't back. Certificates and regulations are yours to word.
- VAT is right for your business.
- Your name, number and the date are right.
What not to paste in
Keep customers' personal details to a minimum. "3-bed semi in Leeds" is enough for the AI. Add the real address in your own document. Check the privacy settings of whatever tool you use. The ICO has guidance on using personal data with AI. Ten minutes well spent if you use it daily.
When not to use it
- Odd or complex jobs. If you don't know what's behind the wall, you need a site visit, not a template.
- Big jobs likely to turn into arguments. Get a proper contract.
- If you won't check it. An unchecked AI quote is a liability.
Make it repeatable
Write one good quote. Save it. Next time, paste it in and say "write the next one in the same style". Keep your price list in a note and paste that in too. It picks up your wording, your layout and your usual exclusions.
Then follow up
A quote sitting in an inbox is a lost job. Two or three days later, send: "Hi, just checking you got the quote. Any questions?" AI can draft that too. It's the easiest win in the whole process.
What I don't know
I'm not a plumber. I don't know your prices, your jobs or your area. I know how to set AI up so it saves you typing. The trade judgement is yours.
Quick FAQ
Does ChatGPT cost anything? There's a basic version at no cost. Paid plans add features. The basic one can draft quotes.
Which tool is best? No single winner. Try two or three. Keep the one that sounds most like you.
Will customers know it's AI? If you've edited it and it sounds like you, it's just a good quote from you.
Is it allowed? Yes. You're responsible for what you send. Same as ever.
