From the AI agent playbooks for gas and heating engineers

Read this first

Trade rule for every job here: the assistant never makes a gas safety, carbon monoxide, defect-classification, "safe to leave on", reportable-incident or technical judgement, and never sees certificate, defect or appliance-fault detail. It never explains a fault code, says whether an appliance is safe, or says what a regulation or standard requires. Those decisions are yours, as the registered engineer, and so are any safety, compliance or warranty words in anything you send. Keep customers' names beyond first names, addresses, phone numbers and certificate numbers out of any AI tool.

Safety rule for every job: a message that mentions a gas smell, a carbon monoxide alarm, fire, flooding, electric shock or injury is a phone call, never a drafted message. The assistant writes no reply to it, puts it at the top of your list, and shows you the emergency wording below so you can read it out or confirm it has gone to the customer. You call them. The assistant never decides whether something is serious.

The emergency wording (Great Britain's National Gas Emergency Service number is used below, and it is for Great Britain only; in Northern Ireland the gas emergency number is different, so check with your gas supplier and put that number in instead; National Gas says the number is open 24 hours a day and free to call, and the HSE gives the same number):

If you smell gas or think there may be carbon monoxide (headaches, dizziness, feeling sick, feeling weak, tiredness or confusion, shortness of breath), stop using appliances if you can, open doors and windows, go outside and call the free National Gas Emergency Service on 0800 111 999 (24 hours). Don't go back in until you've had advice. Don't use light switches or naked flames. Get medical advice as soon as possible (NHS 111). Call 999 if anyone is finding it hard to breathe, has suddenly become confused, has lost consciousness, feels weak or has chest or muscle pain. For fire, call 999.

Your notes on what you will fit turned into a sendable quote with scope and exclusions, safety and warranty wording left to you

Writing up quotes lands at the end of a working day, and a slow quote can lose a boiler job. Turning your own notes on what you will fit into a clean quote with a clear scope, what is excluded, your prices and your terms, ready to check and send the same evening, helps customers compare like with like. The assistant works only from the scope you type and your own price book. It never describes the condition or safety of anything you found: that wording is yours.

Time: about an hour to set up your price book and template, then 10 minutes per quote

You will need: your notes on what you will fit, a "Price book" tab with your own prices, your quote template, your own email or quoting app

Works with: a chat assistant that can read a notes document and a price book sheet and write a draft. Check your tool's current features.

Set it up

  1. Make a "Price book" tab with your own prices for common jobs and line items (labour, call-out, a standard boiler swap, controls, flue parts, filters, powerflush if you offer it) and what each normally includes and excludes.
  2. Write your quote template: your business details, scope, what is included, what is excluded, assumptions, price, how long the price is valid, payment terms and how to accept. Add your standard cancellation wording. Leave a line "[GAS SAFE ID AND SAFETY WORDING: you add it]".
  3. After a visit, type only the scope you will quote: what you will fit or do, the parts, the time and anything you are unsure of. Leave out the address, and leave out what you found about the condition or safety of the existing appliance: you add that wording yourself.
  4. Run the instructions. It fills the template from your notes and your price book only. Any item whose price isn't in the book appears as "[PRICE: you add it]". It lists "Questions for you" and any assumptions made explicit.
  5. Check the scope, parts and every price. Add the Gas Safe details, any safety, condition, regulation, warranty or guarantee wording, and the address yourself, then send it.
  6. Compare a few quotes with what the job cost, and update the price book.

The instructions to give your agent

Copy, paste, then fill in the [brackets]
I am a UK gas and heating engineer. From my notes below and my "Price book" tab, fill in my quote template. Use only the facts in the notes and the prices in the price book. If an item has no price in the book, write [PRICE: you add it]. Do not estimate, round or invent any price, quantity, time or part.
Write the scope in plain words, list what is included and what is excluded, list any assumptions you had to make as "Assumptions", and list anything unclear as "Questions for you". Use my template wording for validity, payment terms and cancellation exactly as written.
Do not make any statement about gas safety, carbon monoxide, the condition of any appliance, regulations, certificates, warranties or guarantees: leave a line "[SAFETY, CONDITION AND WARRANTY WORDING: you add it]". Do not suggest which boiler or part to fit. Do not include the customer's address or phone number. Do not send anything.

✓ Check before you rely on it

  • Check every price, quantity and line against your price book and your notes.
  • Check every "[PRICE: you add it]" is filled by you before it goes.
  • Check the scope says what you will actually fit and the exclusions say what you won't.
  • Check it added no safety, condition, regulation or warranty wording, and no boiler recommendation.
  • Check the full price the customer pays is shown clearly.

✕ What it will not do

  • Invent or estimate a price, recommend a boiler or part, or send a quote.
  • State anything about gas safety, the condition of an appliance, compliance or warranties.
  • Decide from your notes that a job is safe or possible.

⏸ Approval gates

  • Drafted or flagged for you: the quote draft, assumptions and questions.
  • Only you decide: the scope, every price, the terms, any safety, warranty or compliance wording and whether to send.

🔒 Data handling

Notes can contain customers' names and addresses. Leave them out of what you give the assistant and add them yourself. Consumer law applies to quotes: show the full price clearly, and when a customer agrees a job at their home, away from your premises or at a distance (for example online or by phone), you must give certain information, including their right to cancel within 14 days (see UK notes). Check the rules for your situation.

UK notes extra

  • GOV.UK: door to door sales.
  • GOV.UK: online and distance selling.
  • CMA: unfair commercial practices guidance.
  • ICO: advice for small organisations.
