Tradie Forms: avoid loose gratuitous work paperwork. Fill the Tasmania CBOS form in guided sections, check certifier and owner details, capture the owner signature and preview the official PDF before export.

Tasmanian gratuitous work can feel casual because the job is unpaid. The paperwork should not be casual. The CBOS gratuitous work form records who is doing the prescribed work, who owns the property, where the work will happen, what relationship exists, what work is being performed, how the insurance questions are answered and when the owner signs.

This guide covers common mistakes plumbers and gas-fitters make when the form is left until late or treated like a favour note. Use it before you export the TAS Gratuitous Work form, and browse TAS plumbing forms for related paperwork.

Mistake 1: Treating no-payment work as no-paperwork work

CBOS guidance says a certified plumber must complete a Gratuitous Work Form and lodge it with CBOS for assessment by email or post. The official PDF is for "Plumber and/or Gas-fitter (Certifier) only".

That means the form should be treated as part of the job setup, not something to remember after the work is done.

The fix is simple. Open the form before the job details start to scatter. Confirm the current CBOS process, fill the owner and certifier details, answer the insurance questions and capture the owner signature while everyone is available.

For small jobs, do this before tools are packed away. For family or charity work, do it before the favour becomes a memory and nobody can remember the exact work description.

Mistake 2: Certifier details are old or incomplete

The form asks for the certifier's personal and contact details, including licence number. Old saved details can create quiet errors if you do not review them.

Check:

  • Full name
  • Home and postal address
  • Date of birth
  • Licence number
  • Phone numbers
  • Email address
  • Fax if used

Tradie Forms can save certifier details for reuse, but the final check matters. The exported PDF should reflect the current certifier, not whatever was in the last form.

Mistake 3: The owner relationship is vague

The form asks for the relationship or association between the certifier and property owner. This field is easy to rush because the certifier may know the person well.

Do not write "known to me" if a clearer answer is available. Be plain:

  • Parent
  • Sibling
  • Friend
  • Community organisation contact
  • Neighbour
  • Charity contact

Use the wording that honestly describes the relationship. If the relationship does not fit the current CBOS process, check the guidance before continuing.

Mistake 4: The work site is not specific enough

The work site should identify where the prescribed work will be performed. For a standard suburban property, the street address may be straightforward. For rural properties, units, shared driveways or properties with multiple buildings, add enough detail to avoid confusion.

If the job is not easy to identify from the address alone, keep supporting notes with the job record. The form should not leave CBOS, the owner or your future self guessing where the work happened.

Mistake 5: The prescribed work description is too broad

"Plumbing work" or "gas work" is not enough. The official form asks what type of prescribed work will be performed. Describe the actual work.

Better descriptions are specific and short:

  • "Repair sanitary plumbing to bathroom basin waste"
  • "Install replacement gas appliance connection"
  • "Replace damaged section of water pipe at dwelling"
  • "Carry out prescribed drainage repair at rear of property"

The description should match the unpaid work being done. Do not make it broader than the job.

Mistake 6: Insurance answers are guessed

The official PDF includes insurance questions and references liability insurance for personal injury and property damage. Do not tick answers from habit.

Check the current form wording and your insurance position before export. If the property owner is answering part of the insurance section, make sure they understand what is being answered.

Tradie Forms can make sure a field is not left blank. It cannot tell you what the correct insurance answer is.

Mistake 7: Owner signature is left until later

The form includes property owner sign-off. If the owner does not sign while the details are fresh, someone will have to chase them later.

Capture the signature once the owner has reviewed:

  • Certifier details
  • Owner name
  • Work site
  • Relationship or association
  • Description of prescribed work
  • Insurance answers

Do not use a future date. The signature should reflect when the owner signs the form.

Mistake 8: The exported PDF is not lodged or stored

The job is not finished just because the PDF is downloaded. CBOS guidance refers to lodging the form with CBOS for assessment by email or post.

After export, record what happened:

  • "Gratuitous work form emailed to CBOS"
  • "Gratuitous work form posted to CBOS"
  • "Owner signed form, waiting on insurance check"
  • "Exported PDF stored with job record"

Keep the exported PDF with any lodgement email, owner communication, photos, insurance notes and related trade records.

If your business normally relies on invoices to find job files, create a job record anyway. Gratuitous work may not create an invoice, but it still needs a place for the form, owner signature and lodgement trail.

How Tradie Forms helps avoid these mistakes

Tradie Forms turns TAS Gratuitous Work into guided sections for certifier, property owner, work, insurance and owner sign-off.

You can:

  • Fill the form on site from a phone, tablet or laptop
  • Reuse certifier details where they still apply
  • Use address search or manual address entry
  • Catch missing fields before export
  • Preview the official PDF layout
  • Download the finished form for CBOS and your job record

The platform helps keep the paperwork in order. It does not replace checking the official requirements, deciding whether the work qualifies, or confirming insurance answers.

Gratuitous work is a separate pathway from normal start and completion paperwork. If the job is not gratuitous work, related Tasmanian templates include TAS Form 60 for start work notification, TAS Form 71B for standard of work certification and TAS Form 21 for certificate of completion records.

Use TAS plumbing forms to find the right template before filling a PDF.

Final check before export

Before downloading the form, confirm:

  • The job fits the current CBOS gratuitous work process
  • Certifier details and licence number are correct
  • Owner name and work site are accurate
  • Relationship or association is clearly described
  • Prescribed work description matches the actual work
  • Insurance questions are answered against the form wording
  • Owner signature and date are present
  • The PDF will be lodged or stored through your normal process

That is a short check, but it prevents most of the avoidable back-and-forth.

A better on-site habit

Set up the form like any other job pack:

  1. Confirm the pathway.
  2. Enter certifier details.
  3. Confirm the owner and site.
  4. Describe the work.
  5. Check the insurance answers.
  6. Get the owner signature.
  7. Preview the PDF.
  8. Download and lodge or store it.

The habit is simple enough to use on a Saturday favour job and solid enough for your office to understand later.

Keep the language plain

The form is not the place for internal shorthand. Write names, addresses, relationship and work description in words the owner and CBOS can read without calling you. A clear PDF saves everyone time, especially when the job is unpaid and there is no normal invoice trail to explain the work.

Store proof of what happened next

After export, keep more than the PDF. Store the email to CBOS, postage note, owner message or internal job note that shows what happened with the form. If CBOS asks for more information, keep that request and response beside the same file.

That record protects your future admin time. Nobody should have to search three inboxes to work out whether a no-payment job was actually lodged.

For unpaid work, the form and lodgement note may be the only paperwork trail. Treat them like a normal job record.
