Tradie Forms: complete the Tasmania gratuitous work certificate on the official PDF layout before prescribed work starts without charge. Capture certifier, property owner, work description, insurance, and owner sign-off without fighting a flat PDF.

Gratuitous work still needs a clear record. The owner is not paying for the job, but CBOS still expects the certifier, site, prescribed work, insurance declaration, and owner sign-off to be accurate before work begins.

The best time to finish this form is while you are still talking to the owner and checking the site. Licence details, insurance coverage, and the work description are much easier to confirm on site than from memory later.

Use the TAS gratuitous work form as your on-site checklist. More context sits in the Tasmania plumbing forms list.

What the gratuitous work certificate is for

The gratuitous work certificate records prescribed plumbing or gasfitting work performed without charge for a property owner. It is part of Tasmania's building and plumbing compliance paperwork under CBOS.

Use the CBOS approved forms page and the guide to approved plumbing forms as the official references for current requirements.

Details to collect before you export

Certifier details

Add your name, licence number, contact details, and home address accurately. This is the licensed person certifying the gratuitous work.

Check the licence is current and matches the trade scope of the work you are about to perform.

Property owner and work site

Capture the owner name, contact details, and the work site address. The site should match where the prescribed work will happen, not a mailing address copied from an old job.

Prescribed work description

Describe the work in plain language. A vague line like "plumbing repairs" is harder to defend later than a specific scope such as replacing a failed tempering valve or reconnecting a gas appliance.

Insurance declaration

Confirm whether insurance coverage applies and complete the insurance section honestly. If coverage details are unclear, resolve that before work starts rather than guessing on the PDF.

Owner sign-off

The property owner signs and dates the form. Finish the conversation on site so the owner understands what work is being certified.

On-site workflow with Tradie Forms

  1. Open the TAS gratuitous work template on your phone.
  2. Fill certifier, owner, work, and insurance sections while you are still at the property.
  3. Preview the PDF layout before export.
  4. Download the finished PDF and lodge it with CBOS using the pathway required for the job.

Lodgement and record keeping

The template completion notes remind you to post the completed form to CBOS at PO Box 56, Rosny Park TAS 7018, or email cbos.info@justice.tas.gov.au. There are no fees to lodge this form with CBOS.

Keep a copy with the job file so the office can answer questions later without digging through messages.

Common checks before handover

  • Licence number and certifier name match your current credentials
  • Work site suburb and address match the property
  • Prescribed work description is specific enough to explain the job
  • Owner signature and date are complete
  • Insurance declaration reflects the actual coverage position
