What is Electrical Certification?

Electrical certification is a legal document that confirms electrical work or installations have been completed safely and comply with relevant electrical certification requirements in Auckland. This certification ensures that the electrical installation is safe for use and meets the requirements of the law.

Is Electrical Certification Required?

Yes, electrical certification is often required for both insurance purposes and building code compliance. Many insurers now request electrical certification before providing coverage, especially when dealing with older homes that are being sold.

This certification ensures that electrical installations are safe and comply with the required safety standards, reducing the risk of electrical hazards or malfunctions.

Who Issues Electrical Certification?

In Auckland, registered certified electricians are responsible for issuing electrical certifications after completing electrical work. The type of certification depends on the complexity and risk of the job. The more complex or risky the work, the higher the qualifications required of the electrical worker to certify it.

Does an Electrician Need to Provide a Certificate?

Yes, by law, any electrical worker who completes work on an electrical installation must issue certification. This certification must be provided to the person or entity that requested the work within 20 working days of the installation's connection.

Additionally, the electrical worker is required to keep a copy of the certification for at least seven years and must produce it within 10 working days if requested by relevant parties.

Types of Electrical Certification

There are different types of electrical certification, each serving a specific purpose depending on the nature of the electrical work.

Energy Work Certificate

Insurers commonly request an Energy Work Certificate, which is a general term for all types of electrical certification. The specific certification required will depend on the type of installation or work completed.

Certificate of Verification (COV)

A Certificate of Verification (COV) may be required in the following cases:

  • If there are no existing documents and an insurance company requires electrical certification.
  • If electrical work has been completed but certification from the original installer is not available.
  • When an installation has been disconnected for more than six months and needs reconnection.
  • If you believe your installation is unsafe due to age, improper  installation, or damage.
Electrical Safety Certificate (ESC)

An Electrical Safety Certificate (ESC) is issued by registered electrical workers for low-risk work such as maintenance, repairs, or replacements. This certification confirms that the work complies with safety standards.

Electrical Certificate of Compliance (COC)

A Certificate of Compliance (COC) is issued for general-risk electrical work such as new installations, alterations, or additions. The COC includes an ESC section, which verifies the safety of the work performed. This combined document is referred to as a COC&ESC.

Electrical Record of Inspection (ROI)

For high-risk electrical work, an additional level of inspection is required. High-risk work includes:

  • Switchboard upgrades or relocations
  • Mains supply cabling and earthing
  • Solar installations
  • Parallel Generation (such as generator installations)

For these types of work, the electrical worker will issue a combined COC&ESC, and a registered electrical inspector will issue a Record of Inspection (ROI). The ROI is also recorded in Energy Safety’s High Risk Database. Both documents are required for high-risk electrical installations.

Energy Meter Inspections (ROI)

Energy meters are provided by the network retailer in collaboration with a Metering Equipment Provider (MEP). For any work involving energy meters, such as installations, relocations, or rewiring, an inspection by a Network Warranted Electrical Inspector (Warranted Person) is required. This ensures that the meter has been installed correctly and has not been tampered with.

Legislation Governing Electrical Certification

All regulations surrounding electrical certification are outlined in the Electricity Safety Regulations 2010. This legislation sets the standards for electrical safety in New Zealand, ensuring that all installations and electrical work are completed to the highest safety standards. Electrical certification requirements in Auckland are in line with these regulations.
