In South Australia, covered plumbing work needs an electronic Certificate of Compliance (eCoC) within 7 days of completion. The worker and the contractor both sign off, and the customer gets a copy by email or in print. Jobs such as changing tap washers or clearing blocked drains are outside the requirement.[1][2]
Which plumbing jobs need an eCoC
The SA Government lists the covered plumbing work below. Check each job against the list before you close it out.
| Covered by the eCoC | Listed as not covered |
|---|---|
| Pipework and fixtures from the mains water supply or sewer | Changing tap washers |
| Sanitary plumbing and drainage | Clearing blocked drains |
| Water heaters | Installing domestic tapware |
| Backflow prevention | Stormwater systems |
| Alternative water systems | See the listed work-specific exclusions |

Timing, sign-off and the customer copy
For plumbing, the certificate is due within 7 days after the work is completed. The worker and the contractor both sign off.
The eCoC system is free for contractors and workers. Each job gets a unique job number, you can save progress and attach images, and the customer receives the certificate by email or as a print or posted copy. The public cannot log in directly.
Electrical and gas work in the same system have their own timing, so do not apply the plumbing 7 days to them. A submitted certificate cannot be edited, so an error needs a replacement certificate.
Job close-out checklist you can copy
This is our suggested checklist, not a government form. Use the completion date as day 0 and set your own reminder well inside the 7 days.
