Compliance by state

Notice of Intention and Certificate of Compliance in WA plumbing

In Western Australia a licensed plumbing contractor submits a Notice of Intention 24 hours before starting major plumbing work, then a Certificate of Compliance within 5 working days of finishing it, through the plumbing eNotice system (Plumbers Licensing and Plumbing Standards Regulations 2000). The certificate has four copies: the Plumbers Licensing Board, the owner, local government where relevant, and the contractor's own 6 year record.

Official name: Notice of Intention (before major plumbing work); Certificate of Compliance (after major plumbing work)
Regulator: Plumbers Licensing Board, Building and Energy
Who issues it: The licensed plumbing contractor responsible for the work
When: Major plumbing work (Building and Energy's guidance describes the requirement for AMR plumbers undertaking the activities of a licensed plumbing contractor in WA)
Deadline: Notice of Intention: 24 hours before work starts, or with the Certificate of Compliance within 5 working days of completion for emergency work. Certificate of Compliance: within 5 working days of completing the work.
Lodgement: Submitted through plumbing eNotice. The Certificate of Compliance's yellow copy goes to the Plumbers Licensing Board, blue copy to the owner or occupier, pink copy to local government in non-sewered areas.
Keep records for: The contractor keeps the green copy of the Certificate of Compliance for 6 years
Penalty: Not stated in Building and Energy's published plumbing eNotice guidance

Homeowner? If you've had major plumbing work done in WA, you should receive the blue copy of the Certificate of Compliance: it's meant to come to you as the property owner or occupier as part of the plumber's normal process.

What the certificate must show

For drainage work: notification that the work has been completed, tested and is ready for inspection (regulation 70), lodged before the Certificate of Compliance
The completed, signed and dated Certificate of Compliance, in its four coloured copies

Produce it from a ServiceM8 job

In Settings > Forms > Add Form, create a form called Plumbing job WA.
Add Multiple Choice for Work type with options Standard / Emergency / Drainage, and Date for Notice of Intention submitted (required unless Emergency is selected).
For Drainage, add a Checkbox for Ready for inspection notified (regulation 70) that must be ticked before the Certificate of Compliance fields unlock.
Add Text for Certificate of Compliance reference and a Date field for Date lodged, both required.
Attach the form to two job badges: NOI lodged, mandatory before dispatch for non-emergency work, and CoC lodged, mandatory before the job can be marked complete.
Set a job reminder 4 working days after completion so the 5 working day Certificate of Compliance deadline is never the first anyone notices it.

Before work: the Notice of Intention

A Notice of Intention must be submitted to the Plumbers Licensing Board 24 hours before major plumbing work starts. Building and Energy's own guidance describes this obligation for AMR plumbers, meaning plumbers licensed elsewhere in Australia and practising in WA under automatic mutual recognition, undertaking the activities of a licensed plumbing contractor. Emergency work is the one exception: if the job is genuine emergency plumbing work, the 24 hour advance notice does not apply, but the Notice of Intention still has to be provided, alongside the Certificate of Compliance, within 5 working days of the work being finished.

After work: the Certificate of Compliance and its four copies

Within 5 working days of completing major plumbing work, the plumbing contractor completes, signs and dates a Certificate of Compliance. It is a four part form: the yellow copy is the original, and it goes to the Plumbers Licensing Board. The blue copy goes to the property owner or occupier. The pink copy goes to the local government authority, but only in non-sewered areas. The green copy stays with the contractor, who keeps it for 6 years.

Drainage work has an extra step

For drainage plumbing specifically, the work has to be notified as completed, tested and ready for inspection before the Certificate of Compliance can be lodged. That notification sits ahead of the certificate in the sequence, not alongside it, so a drainage job that skips straight to lodging the certificate is out of order even if the paperwork itself is otherwise correct.

A separate system from gas eNotice

Plumbing eNotice and gas eNotice are two different services under Building and Energy, so a business doing both plumbing and gasfitting work in WA lodges through two systems rather than one. The underlying pattern is the same in both: something submitted before the work (a Notice of Intention for plumbing, nothing equivalent for standard gasfitting) and something submitted after (a Certificate of Compliance for plumbing, a Notice of Completion for gas), each going to the regulator and to the customer.

Tracking the two deadlines in ServiceM8

Because the Notice of Intention deadline sits before the job starts and the Certificate of Compliance deadline sits after it finishes, they need two separate checkpoints rather than one end of job form. Add a job badge such as NOI lodged that has to be ticked off before the crew is dispatched for anything but emergency work, and a second badge Certificate of Compliance lodged that becomes mandatory once the job is marked complete, with a 5 working day reminder built into the job schedule so it doesn't slip past the deadline."
