A cover letter for a tradesperson works best when it is short: three paragraphs, not three pages. Employers hiring electricians, plumbers, welders and other trades often read ten or more trades cover letters in one sitting, and a long one can bury the two or three facts that actually decide whether you get a call back: your ticket, your experience, and when you can start. Here is a structure that keeps a trades cover letter short and specific, a sample electrician cover letter you can adapt for your own trade, and the lines that are better left out.
Why length works against you in the trades
A hiring manager or site supervisor scanning applications is usually looking for the same handful of things: do you hold the right licence or ticket, have you done this type of work before, and are you available when the job starts. A one-page resume already carries most of that detail. A cover letter that repeats your whole work history in paragraph form makes the reader hunt for what is new.
A short trades cover letter does the opposite. It tells the reader, in the first two lines, which role you want and why you are a fit, then backs that up with one or two concrete examples instead of a list of adjectives. "Hard-working and reliable" says nothing a resume does not already imply; "I have run service calls solo for three years and hold my own test and tag ticket" says something specific that a reader can act on.
Three paragraphs, three jobs to do
A cover letter for a tradesperson can do its job in three short paragraphs, each with one clear purpose.
- Open with the role and the strongest match. Name the job and the one or two qualifications that matter most for it (a ticket, a licence, years in that exact trade).
- Give one concrete example. A short, specific example of work you have done that matches what the ad asks for, with a real detail (the type of job, the site, the outcome) rather than a general claim.
- Close with availability and a simple ask. When you can start, how to reach you, and a short line inviting the next step.
Paragraph one: the role and the match
Name the job title from the ad and the licence, ticket or years of experience that line up with it. If the ad asks for a current electrical licence and three years on commercial sites, say exactly that you hold both, in one sentence.
Paragraph two: one example, not a list
Pick the single piece of work closest to what this employer needs and describe it in two or three sentences: what the job was, what you did, and what the result was. One well-chosen example reads as proof; five short ones read as padding.
Paragraph three: availability and the close
State your notice period or start date plainly, then close with a short, confident line such as asking for a call to discuss the role. No need to repeat your resume's contact details if they are already on the letter header.
A sample electrician cover letter
Example (fictional applicant, for an electrician cover letter):
Dear Hiring Manager,
I am applying for the Maintenance Electrician role advertised this week. I hold a current electrical licence and have worked on commercial and light-industrial sites for the past four years, most recently as a solo service electrician covering fault-finding, switchboard upgrades and emergency callouts.
In my current role I was the only electrician on site for a 40-store retail fit-out, where I diagnosed and fixed a recurring switchboard fault that two previous contractors had missed, bringing the store back online within a single shift. I am used to working to deadline on live sites with minimal supervision.
I can start within two weeks of an offer and am available for a trade test or interview at short notice. I would welcome the chance to discuss how my experience fits this role.
Kind regards,
J. Alvarez
Notice what the example leaves out: no list of personality traits, no repeated resume bullet points, and no paragraph explaining what an electrician does. The reader already knows that; they want to know what this applicant has actually handled.
What to leave off a trades cover letter
A few things weaken a trades cover letter more than they help it:
- A full work history. That is what the resume is for. Repeating every job in paragraph form just lengthens the letter without adding proof.
- Generic adjectives with no evidence. "Motivated", "hard-working" and "team player" mean little without a specific example attached.
- Apologising for gaps or a career change. State the fact plainly (a gap, a move from another trade) in one neutral line if it is relevant, rather than over-explaining it.
- Anything that does not match this specific job ad. A cover letter written once and sent everywhere tends to read that way. Swap in the ticket, trade and example that match the role in front of you each time.
Email body or an attached letter?
Either works, and most employers accept both. If you are applying by email with no separate cover letter requested, the same three paragraphs can simply be the body of the email, with your resume attached as a PDF. If the job ad or an online form asks for a cover letter specifically, attach a short PDF that matches the formatting of your resume so the two documents read as one application.
Build AI CV's cover letter builder lets you write the three paragraphs yourself for free, or ask AI to draft the body from your saved CV and the job ad you paste in, for 2 credits; either way you edit every line before it goes anywhere. Add your signature from a photo and download a PDF that matches your CV's template, so an attached letter and resume look like a single, tidy application. If you have not built your CV on the site yet, you can start one free as a guest before you write the letter, so the AI draft has your real experience to work from.
If you are starting from scratch, the site's electrician CV example shows how the same licence-first, example-led approach works on the resume itself, and the wider CV examples page covers other trades. If your resume already leans heavily on a list of tickets and machinery, it's worth checking that list is pulling its weight rather than just naming equipment with no context, since the same problem that weakens a cover letter can weaken a resume's skills section too.
Frequently asked questions
How long should a trades cover letter be?
About three short paragraphs, well under one page. Most readers scan a cover letter in under a minute, so anything that takes longer to read than that is probably repeating the resume.
Do I need a different cover letter for every job?
The structure can stay the same, but the ticket, trade and example in it should match the specific job ad each time. A letter that could be sent to any employer tends to read as if it was.
Should I mention pay or sponsorship in a cover letter?
Only if the ad asks for it directly. Otherwise, keep the letter focused on fit and availability, and leave pay and visa questions for the interview or the application form where they are usually asked.
What if I am changing trades or have a gap in my work history?
State it plainly in one line rather than explaining at length. "After four years as a plumber, I completed my electrical apprenticeship and am now looking for my first role as a qualified electrician" tells the reader what they need to know without sounding defensive.
Can AI write the whole letter for me?
AI can draft a starting point from your CV and the job ad, but it only works from what you have actually entered, and you should read and adjust every line before sending it, since only you know which example best matches the job.
