Plumbing & Gas CoC -- Where To Check
Plumbing & Gas CoC -- Where To Check
People ask for a single national expiry date for a plumbing or gas Certificate of Compliance the way the electrical CoC has its 2-year transfer rule. There is not one. Here is what is actually true, and who to confirm with.
Plumbing CoC -- no single national rule
- A plumbing CoC (or completion certificate) is required under some municipalities' by-laws -- on new work, or on transfer of property in some areas
- There is NO single national validity period equivalent to the electrical CoC 2-year transfer rule
- Confirm with your municipality and the Plumbing Industry Registration Board (PIRB) or IOPSA
Gas CoC -- different regime
- Gas installations are governed by the Pressure Equipment Regulations under the OHS Act
- A gas Certificate of Conformity is issued by a SAQCC Gas registered practitioner; it is required on a new or altered installation and is commonly requested on property transfer
- There is no single nationally standardised transfer-of-property expiry period in the secondary sources -- confirm against the regulation text and your insurer's requirement
What we will not do
- We will not print a number of years for a plumbing or gas CoC, because no reliable single national figure exists -- a wrong validity period here could fail a property sale
We do not state a plumbing or gas CoC validity period because there is no single national rule. Confirm with your municipality (plumbing by-laws), PIRB / IOPSA, and SAQCC Gas / the Pressure Equipment Regulations. The electrical CoC 2-year transfer rule is on the separate electrical CoC card.
