Why We Built Free AI Courses for Electricians, Plumbers and Other Trades

Who AI training forgets

Look at almost any AI course and you can guess who it was written for. Someone at a desk, with a laptop, a calendar full of meetings and a company that pays for the training. The examples are about writing reports, summarising slide decks and analysing spreadsheets.

That leaves out a lot of people who do skilled work for a living. An electrician or a plumber spends the day on site, with a phone in their pocket rather than a laptop on a desk. Many run their own small business, which means that on top of the job itself they write the quotes, answer the customers, chase the invoices and keep the records. A lot of that happens in the evening, after a full day of work.

Those are exactly the jobs a chat AI on a phone is good at helping with. Yet the people who could save the most time are the least likely to be offered any training at all. That is why we built a Trades area.

What we built

There are three courses so far, and all of them are free:

  • AI on the Job (6 lessons) for electricians, plumbers and other trades. Use a chat AI on your phone to write quotes from your notes, answer customers, think through a fault, find the right page in a manual and get your evenings back from the paperwork.
  • AI for Electricians (4 lessons). Quote electrical jobs from your survey notes, read labels and old paperwork from a photo, do the sums with the working shown, and write up job records and handover notes.
  • AI for Plumbers (4 lessons). Quote plumbing jobs from your visit notes, check boiler and heater error codes against the maker's manual, think through leaks and damp from a photo, and write plain notes for customers.
  • We designed them around how people in the trades actually work:

  • On your phone. Everything works in the phone's web browser. There is nothing to install, and no laptop is needed.
  • Short. Each lesson takes between 6 and 12 minutes, so it fits into a break or the end of the day.
  • From the very start. The first lesson explains what AI is, the kinds of AI you will hear about, and how to put a chat AI on your phone, step by step. We do not assume anyone has used one before.
  • Real jobs. The examples include a boiler job, an EV charger quote, a pump change and a late invoice, with made-up but realistic notes, price lists and manuals.
  • Catch the AI out

    Chat AI is useful, but it gets things wrong, and it sounds just as sure of itself when it is wrong as when it is right. For someone writing a quote, a mistake costs money. On a job site, a mistake can be dangerous.

    So the most important skill in these courses is checking. Nearly every lesson has a step we call Catch the AI out. The learner sees something an AI has written and has to find the mistakes before they use it. A few examples from the lessons:

  • A quote where the AI used the wrong length of pipe and the wrong hourly rate. The total looks close enough that it would be easy to send.
  • An answer that points to section 4.7 of a water heater manual. The manual has no section 4.7. The AI made it up.
  • A photo of a faded label on an old control box. The AI reads most of the terminals correctly, misreads a faded 8 as a 3, and then adds that a wire is safe to disconnect, which it has no way of knowing.
  • After a few of these, people stop treating the AI as an expert and start treating it as a quick helper whose work they always check. That habit matters more than any single trick.

    What the courses do not teach

    These courses teach you how to use AI in your work. They do not teach electrical, gas or plumbing work, and they do not replace your training, your licence or the rules where you work. The AI can help you read a label or find the right page in a manual. It never decides whether something is safe. That stays with you.

    Why they are free

    We charge for most of our courses. We decided the trades courses should be free for three reasons.

    First, the people we built them for are mostly sole traders and small firms, with no training budget and no one in HR to approve one. Asking them to pay before they know whether AI is any use to them would keep out the very people we want to reach.

    Second, an hour back each evening is worth more to a one-person business than almost anything else we could teach. If these courses save someone time on quotes and paperwork, that is a good result whether or not they ever take another course with us.

    Third, using AI safely should not depend on what you can pay. If tradespeople are going to use AI on the job, and many already are, we want them to learn to check it.

    The trades courses do not use up the free first course that every learner gets, and you do not need a card to start.

    What comes next

    Electricians and plumbers come first because their jobs have the clearest mix of quoting, fault-finding, manuals and paperwork. We plan to add more trades, and we would like to hear from people in the trades about which jobs they want help with.
