Plumber cover letter example

Plumbing employers want to know your registration class, the work you run and whether it passes inspection. This example is from the same certifying plumber as our CV example, applying for a supervisor role, and every claim comes from his CV.

Re: Plumbing Supervisor, residential new builds

Kia ora Sarah,

I'm applying for the Plumbing Supervisor role on your new build team. I'm a certifying plumber with eight years since qualifying, and at Tōtara Plumbing in Auckland I run the plumbing on 15 to 20 townhouse new builds a year, from rough-in to final fit-off.

A supervisor has to get work signed off and keep a crew moving. I book and attend our council inspections, and last year my first-time pass rate was above 95 percent. I supervise a licensed plumber and a third-year apprentice, checking and signing off their work, and I price variations on site so clients approve changes before work goes ahead. I also test and certify backflow devices for 40 commercial maintenance clients each year. Before Tōtara, I did bathroom and kitchen renovations and maintenance at Kākā Plumbing and Gas, so I plan new builds knowing what a house has to stand up to later.

I'd like to take the next step with a firm that focuses on new builds, where planning jobs from the drawings and running a small crew is most of the work. That's the part of the trade I do best and want to grow in.

I'm a certifying plumber with a current practising licence from the Plumbers, Gasfitters and Drainlayers Board, and I hold a Site Safe passport and a full driver's licence with my own tools. I'd be glad to meet on site or in the office.

Ngā mihi,

Hemi Parata

  1. 1Opens with the class and the workloadCertifying status and 15 to 20 new builds a year tell a manager in two lines that he already carries the load a supervisor does.
  2. 2Proof matched to a supervisor's jobInspection pass rates, signing off others' work and pricing variations are the things a supervisor is trusted with, and his renovation years show he knows the long-term side of the trade.
  3. 3Why this firm, kept shortIt ties the move to the firm's type of work and the step he wants, without claiming anything about the firm he can't know.
  4. 4Licence and an easy closeRegistration class, practising licence and own tools are what a plumbing employer checks first, and offering to meet on site fits how trades hire.

Opening lines

Other ways to open.

The first line decides whether the rest gets read. Each of these names the job and leads with proof. Swap in your own facts.

  • “I'm applying for your Certifying Plumber role, bringing eight years since qualifying and a first-time inspection pass rate above 95 percent last year.”
  • “As a certifying plumber who already supervises a licensed plumber and an apprentice, I'd like to be considered for your Plumbing Supervisor position.”
  • “I'm applying for the Backflow Technician role, where I can build on testing and certifying devices for 40 commercial clients each year.”
  • “After running the plumbing on 15 to 20 townhouse new builds a year, I'm applying for your Senior Plumber vacancy on residential projects.”

Common mistakes

What gets plumber letters skipped.

  • Leaving out your registration class.

    Say whether you're a tradesman, licensed or certifying plumber, and that your practising licence is current. Employers screen on it first.

  • Saying your work is high quality without proof.

    Give an inspection pass rate or the number of jobs you run a year. Numbers like these show quality better than adjectives.

  • Covering plumbing, gas and drainage equally when the job is one of them.

    Lead with the work the ad is about, such as new builds or maintenance, and keep the rest to a line.

FAQ

Questions, answered.

Something else on your mind? Email support@smartcvs.ai and a person will reply.

Do plumbers need a cover letter in New Zealand?

For most tradesman roles a short email is enough, but a letter helps for supervisor, certifying or commercial roles, where the employer wants to know how you run jobs and people.

Should I mention gasfitting and drainlaying if the job is plumbing only?

A short mention is fine, since it shows range and can help on mixed jobs. Keep the letter focused on the plumbing work the ad asks for.

How do I show I can supervise if I've never had the title?

Describe what you already do, such as checking and signing off an apprentice's work or running jobs from rough-in to fit-off. That's the proof an employer looks for.
