What happens when one electrician issues a Certificate of Compliance and another later says that the installation is not compliant?
A conflicting Certificate of Compliance ("CoC") does not necessarily mean that the original certificate was incorrectly issued.
The difference may arise because:
- Electrical work was carried out after the original CoC was issued;
- The electricians disagree on the interpretation of an applicable standard;
- Defects were overlooked during the original inspection; or
- The installation has deteriorated over time.
Before taking action, gather:
- The original CoC;
- The accompanying test report;
- The issuing electrician's registration details;
- Details of any electrical work completed after the CoC was issued;
- The second inspection report;
- Photographs; and
- All relevant correspondence.
Where the dispute concerns the interpretation of an applicable health and safety standard, the Electrical Installation Regulations provide a formal dispute-resolution process involving the Chief Inspector.
However, not every disagreement follows the same legal route. Defective workmanship, negligence, consumer disputes and contractual issues may require different remedies.
Before cancelling a sale agreement, delaying transfer or withholding payment, obtain both legal and technical advice to understand your rights and obligations.
