25 AI prompts for builders, electricians and plumbers

These are 25 prompts you can paste into a chat tool today. They are for builders, electricians, and plumbers, and they work the same way for other trades. Each one has brackets. The brackets are yours to fill. If you leave a bracket empty, the tool should say so, not guess.

Shaun, 20+ years in UK construction, keeps the prices, the measurements, and the registrations in his own notes, and uses prompts only for the wording. We search the AI world every week so you don't have to. A prompt does not know the job. You do.

The UK Trades AI Prompt Pack is free when you sign up to the weekly email. It is a download of prompts for quotes, chasing payment, tax admin, and customers. The 25 on this page are a set you can copy now. Sign up on the home page if you want the pack as well.

How to use any of them

Write the facts down before you open the app. Price, dates, what is included, what is not, and how you want paying. Paste the prompt, then replace each bracket with your own words. Leave a bracket as [missing] if you do not know yet. A filled bracket is a fact. An empty one is a gap. The tool's job is to keep the gap visible.

Here is the difference on a quote. Weak fill: "Price: about a grand, usual deposit." The draft will invent a total and a due date. Better fill: "Total: £1,240. Deposit: £400 before materials are ordered. Balance within 14 days of the invoice. Not included: making good the decoration, and any rotten timber we cannot see yet." Those figures are an example of how to type a decision you have already made. They are not a rate for your job.

Read the draft once for numbers and once as the customer. A builder's customer wants the start, the price, and what happens if the floor is worse than it looked. A spark's customer wants to know whether the consumer unit is in the price. A plumber's customer wants to know who supplies the boiler. If the draft answers a question you did not ask, take that sentence out.

Delete any promise you would not say out loud. "Fully guaranteed" and "all making good included" are the usual ones that appear uninvited. Send the message from your own email or your usual text thread, and keep a copy there. The chat is not your filing cabinet.

Do not paste card numbers, one-time codes, or a registration number you have not checked on the public register. A town and the work is enough for a first draft. Add the house number yourself when you send it.

Use a fresh chat for each customer. A thread that still contains yesterday's bathroom will mix the names, and you will not notice until the email has gone. If you are pricing three jobs in a morning, three chats. The prompts are the same. The notes are not.

Quotes

Start with these if you only have ten minutes. A quote prompt should put your price at the top and keep your exclusions. The longer guides on quoting and invoices go into the checks. These five are the short versions.

Turn these site notes into a scope of works for a UK customer. UK English. Do not add tasks, materials, or guarantees I did not mention. Do not add a price. If a measurement is missing, write [measure].

Trade: [builder / electrician / plumber / other]
Notes: [paste]

Write a quote email. UK English. Use pounds. Put the total in the first lines. Do not change my figures. Do not add work that is not in the scope.

Customer: [name]
Job: [one line]
Scope: [what is included]
Not included: [exclusions]
Total: £[amount]
Deposit: [amount or "none"]
Valid until: [date]

List the exclusions for this quote as short lines a customer can read on a phone. Use only the exclusions I give you. Do not soften them. UK English.

Exclusions: [paste]

Write the payment lines for a quote. UK English. Use my words for the amounts and the timing. Do not add interest, late fees, or a contract clause I did not type.

Deposit: [when and how much]
Balance: [when]
Who pays for materials: [me / the customer]
VAT: [not registered / included / extra, as I have written]

Add one plain sentence to this quote: the price can change if we uncover a problem that was not visible. Use only the example I give. Do not name other problems. UK English.

Example of what might be hidden: [for example rotten joists, or "do not mention a specific fault"]
Quote so far: [paste]

Customers

These are for the messages that are not a formal quote. Keep them short. A customer on a building site will read two lines, not a letter.

Reply to this message from a customer who wants a price before I have seen the job. UK English. Do not give a price. Ask for the facts I list. Be polite and brief.

I need: photos, the town, what they want done, and whether anyone lives in the property during the work.
Their message: [paste]

Write a text to say I am running late. UK English. Use my new arrival time. Do not apologise more than once. Do not offer a discount.

Customer: [name]
New time: [time]

Write a message asking a customer for photos before I visit. UK English. Say what to photograph. Do not promise I can quote from the photos alone.

What I need to see: [for example the consumer unit, the leak, the whole wall]

Write a short message declining this job. UK English. Give the reason I have written. Do not invent a reason. Do not suggest a price to win it back.

Reason: [fully booked / outside the area I cover / not the work I do]

Explain this extra work to the customer. UK English. Keep my price for the extra. Say it is not included in the original quote. Do not start the extra work in the message.

Original job: [one line]
Extra: [what and why]
Price for the extra: £[amount]

Getting paid

The figures stay yours. A prompt can make the chase clear. It should not invent a legal threat. For business customers and the late-payment rules, use the invoice guide and the GOV.UK pages linked from it. Do not let a draft add interest you have not worked out.

Draft a UK invoice from these notes. Do not invent prices, dates, quantities, or bank details. If something is missing, write [missing: what].

Invoice number: [number]
Dates: [invoice date and the date of the work]
Customer: [name and address]
Work: [lines and amounts]
Total: £[amount]
VAT: [as I have written, or "not registered"]
Pay to: [the details I use]

Write a polite payment reminder. UK English. No interest, no courts, no debt collectors. Do not apologise for asking.

Customer: [name]
Invoice: [number]
Amount: £[amount]
Due date: [date]
How they can pay: [as on the invoice]

Write a firmer reminder. UK English. Calm. Use only the next step I have written. If I left the next step as "I will write again", do not upgrade it.

Invoice: [number]
Amount still unpaid: £[amount]
Original due date: [date]
Pay by: [new date]
Next step I will actually take: [your words]

Write a message asking for the deposit before I order materials. UK English. Use my amount. Say I will order when the deposit arrives. Do not threaten.

Deposit: £[amount]
What it covers: [materials / the start of the job]

Materials, the van, and the people on the job

These prompts sort lists. They do not calculate how many bags you need. Read the tub, the length, and your own take-off. If you want the tool to draft a list, give it the quantities you have already counted.

Turn this scope into a materials list for me to check. UK English. Use only materials I named. If a quantity is missing, write [quantity]. Do not estimate quantities.

Scope: [paste]
Materials I named: [paste]

From this job list, write a morning note of what must be on the van. UK English. Do not add tools I did not mention.

Tomorrow's jobs: [paste]
Gear I said I need: [paste]

Write a short note for a new starter on this task. UK English. Short lines. Use only the steps and the warnings I give. Do not add extra safety rules.

Task: [what]
Steps: [your order]
Warnings I want included: [your words]

Write a supplier order I can send by text or email. UK English. Use my quantities and product names exactly. Do not add items. Ask them to confirm the price and the collection or delivery day.

Supplier: [name]
Order: [lines]
Account name if I gave one: [name or "none"]

Reviews and complaints

Reply as yourself. A public review is not the place for a row, and it is not the place for a customer's address. The prompt can hold the tone. You check the facts.

Draft a reply to this complaint. UK English. Acknowledge the point they raised. Use only the remedy I have written. Do not offer money or extra work unless it is in my remedy. Do not argue.

Their message: [paste]
Remedy I will offer: [your words, or "I need to visit before I offer anything"]

Draft a public reply to this review. UK English. No surnames, no address, no job price. Thank them if there is a fair point. Say how they can contact me. Under 80 words.

Review: [paste]
How they can reach me: [phone or email]

Write a short message asking a customer for a review, after the job is finished and they have paid. UK English. One ask. No discount for a review. Tell them which site.

Site: [Google / Checkatrade / Facebook]
Their name: [first name]

Admin you will actually reuse

The last four are for notes you already have. The tool sorts them. It does not know your diary, your certificates, or next week's parking.

Turn this voice note into a job sheet with headings: customer, address, work, exclusions, price if I said one, next step. UK English. Do not add facts. Mark unclear words as [check].

Note: [paste, after you have corrected obvious errors]

Make a reminder list from these certificate and expiry dates. UK English. Do not change a date. If a date is missing, write [date]. Sort them with the soonest first.

Items: [name and date, one per line]

Write a text about access for this job. UK English. Use only the points I list: parking, where to put a skip or a van, pets, and the hours I can work. Do not add rules.

Points: [paste]

From this list of jobs, write a next-week note I can send to myself. UK English. Keep my order. Do not add jobs. Flag any job with no day next to it.

Jobs: [paste]

When the answer is wrong

A wrong answer is usually a fluent one. It has added a start date, a guarantee, a product, or a legal threat you did not type. Paste it back and say what to remove. If it happens twice, write the message yourself from your notes. Five minutes of your own words is better than a draft you do not trust.

Use one prompt for one job. A thread that still contains yesterday's customer will mix the names. Start a fresh chat when the job changes.

The prompts above are enough to cover a normal week: a quote, a customer who wants a price from a photo, a deposit before you order the boiler or the cable, and a review request once they have paid.
