In Victoria, a licensed plumber must issue a compliance certificate when the total value of the plumbing work exceeds $750, counting labour, materials, appliances and GST, including materials or appliances supplied by the customer. Some work needs one whatever it costs. Give the customer the certificate within five days of completion or termination of the contract, and lodge it with the Building and Plumbing Commission (BPC) through VBA360 within five days of completion.[1]
When one is required
Only a licensed plumber can issue a compliance certificate. Registration alone is not enough. The $750 threshold counts labour, materials, appliances and GST, even when others supply the materials or appliances.
Work in the second row of the table needs a certificate regardless of cost.
| Trigger | Detail |
|---|---|
| Total work value | More than $750 including labour, materials, appliances and GST |
| Any cost | Installing, relocating or replacing a Type A gas appliance, converting fuel, installing, modifying or relocating consumer gas piping (other than gas company work), below-ground sanitary drains and gullies, and cooling tower system work |

Five days, not business days
The customer copy is due within five days of completion or of termination of the contract. The lodgement with the BPC through VBA360 is due within five days of completion. The BPC counts these as five days, not business days.
Where applicable, record the eleven-digit consent number and confirmation that the as-laid plan was lodged with the water authority. Include the appliance, fixture and scope details.

Whose work you can certify
A licensed plumber can certify work they carried out or completed, supervised, or engaged another licensed plumber to do. When taking over earlier work, the issuing plumber must inspect or test that work, complete or supervise the remaining work and state compliance. Incomplete work still needs the required certificate, recording why it stopped and the stage reached.
Complex gas work such as Type B appliances is overseen by Energy Safe Victoria and is a separate process.
