Your experience in this trade

If you’ve been working as a plumber installing, maintaining, or repairing water, sanitary, sewerage, drainage, roofing, or gas systems, the correct qualifications and licence are essential.

The RTO assesses your experience against the qualification standard. Confirm the separate licence requirements above with the regulator before you apply.

Delivering RTOs

The partner RTO assesses your evidence and issues your qualification.

All qualifications are nationally recognised and issued by our partner RTOs. Qualification availability and partner details are confirmed during your review. For a licence, confirm the exact accepted qualification and units with the regulator; every qualification listed here may not meet those requirements.

How to Get a New South Wales Plumbing Trade Licence

  1. Free skills review

    Tell us about your trade background, years of experience and any certificates you hold. We check which qualification fits and whether your work history suits RPL.

    Already have the qualification? We’ll confirm it’s the right one for your licence and can pass you to Trade Licence Solutions, our trade licensing team, to help prepare your application.

  2. Build your evidence portfolio

    Your RPL it account manager helps you gather a clear portfolio of evidence: resume, job history, photos of work, reference letters, certificates and more.

  3. RTO assessment

    We submit your portfolio to a partner RTO. The RTO may ask for more evidence or a short interview, and, if you are assessed as competent, issues your nationally recognised qualification.

  4. Apply for your licence

    Once your qualification is issued, you apply to Building Commission NSW, yourself or through Trade Licence Solutions, our trade licensing team. Building Commission NSW decides your application.

RPL it Australia provides guidance and evidence support. The RTO makes the assessment decision; the regulator makes the licence decision.

To support your experience, consider providing any of the following evidence:

  • Resume with industry experience & job roles
  • Employment contracts, job descriptions
  • Reference letters from employers, managers, and colleagues
  • Professional trade memberships
  • Photos or videos of completed work
  • Licences, tickets, or certifications already held

Fantastic service, advice and support! Well done RPLit!!!

Thomas Phan

Couldn't be happier with the service from Adam! I was a bit skeptical at first since everything seemed quite easy to achieve. But Adam knew his stuff, and he guided me through the process very efficiently, and supported me with any queries along the way. It only took me nearly 2 weeks to get my Diploma with NO tasks required, purely from my profile.
