Quick answer
How can a tradesperson use ChatGPT?
ChatGPT, and others like Claude, Gemini and Copilot, can sort your notes, tidy up a message, make a checklist, compare options or spot questions you've missed. They can also get things wrong, or make things up, and sound very sure about it. So check everything it gives you.
The jargon
The words you'll come across, in plain English.
- AI: artificial intelligence: computer tools that can write, answer questions or make pictures from what you type.
- ChatGPT: an AI chat tool made by OpenAI. Claude, Gemini and Copilot are similar tools from other companies.
- Prompt: what you type to tell an AI tool what you want.
- Draft: a first version you check and change before using.
- Training: AI companies using chats to improve their tools. You can often turn it off.
- Temporary or incognito chat: a chat mode that isn't kept in your history or used for training.
Ask it properly
How do I ask ChatGPT properly?
Ask like this
Rewrite this appointment message in plain UK English. Keep the date, price and cancellation wording exactly as they are. Give me one short text.
Not like this
Make this better.
Say who it's for, what it's for, paste in your facts, say what mustn't change, and say what you want back.
Good uses
What is ChatGPT good for?
- A customer update from facts you've checked
- Turning job notes into a checklist
- Questions to ask on a site visit
- Making technical wording simpler
- A few ideas for a headline
- Checking spelling
A safe routine
What's a safe way to use it?
- Decide: exactly what you want
- Strip out: anything it doesn't need, like names and addresses
- Ask: with your facts, what mustn't change, the tone and the format
- Check: every fact against your own records
- Own it: put it in your own words and send it the normal way
A heating engineer might ask it to shorten an appointment message. They still check the date, arrival time and number before sending. If something needs an inspection, a live price, a qualified judgement or legal advice, get that. Don't keep asking the AI until it says what you want to hear.
A request to reuse
Is there a request I can reuse?
Task: [what you need]. Who it's for: [customer, supplier]. Facts: [from your records]. Don't change: [dates, prices, wording]. Don't add: [promises, claims, guesses]. Tone: plain UK English. Format: [text, email, checklist]. Last step: list anything I need to check.
Save it without any customer details, and improve it when the same mistake keeps cropping up.
Check it
How do I check what it writes?
Check names, dates, measurements, prices, legal points, safety steps and links against your own records. Never use AI as the final word on safety, tax, law, staff, insurance or customers' rights.
Keep things private
How do I keep things private?
Never paste customers' addresses, key safe or alarm codes, bank details, ID, health information, passwords or private contracts into an AI chat. Check its privacy settings before using anything about customers or staff. In ChatGPT, you can stop your chats being used to train it.

FAQs
Frequently asked questions.
Is ChatGPT always right?
No. It can be confidently wrong, including with sums and sources.
Can it write my quotes?
It can help with the wording. You decide what's included, the quantities, the price and the terms.
Can I paste a customer's email into it?
Only if you need to, and take out their name and details first.
Will it make me sound like a robot?
It can. Give it an example of how you write, then edit it in your own words.
What if it gives me two different answers?
Trust neither. Go back to your records or a proper source.
Can it diagnose a fault?
Don't rely on it for anything safety critical. Follow proper procedures and the manufacturer's instructions.
