Welcome to eCoC

The Office of the Technical Regulator (OTR) is responsible for compliance with legislation and applicable technical standards in the electricity, gas and water industries to ensure the safety of workers, consumers and property.

With the aim of improving business efficiency, improving compliance, and creating a central source of Certificates of Compliance (CoCs) for Electrical, Gas and Plumbing; the OTR is implementing the eCoC (electronic Certificate of Compliance) system, which is accessible via desktop and mobile devices using the internet.

eCoC is available to licensed plumbing, gas and electrical workers and contractors, and to licensed building contractors. 

If you have not previously registered your licence details on the eCoC system, please register below. If you are already registered, please sign in.

Training and Information

Contractors and workers can get support on how to register and use the eCoC system by:

  • Attending roadshows and information sessions once scheduled;
  • Accessing the quick reference user guides and supporting videos

Please email any queries to; visit The eCoC section of the Energy and Mining website for updates.

ACCC battery recall – LG Chem, SolaX or Opal

The ACCC is urging consumers to urgently check if their LG, SolaX or Opal home energy solar systems are affected by dangerous LG solar energy storage batteries which are under recall, and if so to contact the manufacturer, immediately.

The batteries can overheat and catch fire, which could lead to serious injuries, death and property damage.

LG has indicated it has taken a number of measures to reduce these risks for consumers (including measures to reduce the maximum state of charge to 75 per cent until the battery is replaced). More information about state of charge reductions on LG’s website or on the recall notice.

Consumers can visit the LG Energy Solutions website and use the serial number checker, to identify whether their product is recalled.

To facilitate complete and accurate tracing, installers are requested to register their installations on the LG Energy Solution Australia Product Recall Portal here: Recall Portal Where a battery serial number is not known, LG Energy Solution will pay for installers to visit site and determine the serial number.

Owners of recalled batteries should immediately contact LG Energy Solution Australia on 1300 677 273 or email to arrange an inspection.  If you have a SolaX or Opal system, contact SolaX Power on 1300 476 529 or email

Have you commissioned your inverter correctly?

The OTR has become aware of a number of solar and battery installations where inverters have not been correctly commissioned to the current Australian Standards.

AS/NZS 4777.2:2020 became mandatory in December 2021, and grid connected inverters are now required to be configured to AS/NZS 4777.2:2020 Australia A default settings.

New inverter installations are not permitted to be configured to AS/NZS 4777.2:2015 settings.

AS/NZS 4777.2:2020 introduced a range of important changes to the performance of solar and battery inverters, which are important to the stability of the grid and allow embedded generator installations to better manage disturbances seen on the grid. Rooftop solar is now in aggregate the largest generator in South Australia and it is critical to the future of solar that these operate predictably and reliably.

The OTR will be examining commissioning of inverters to ensure compliance, penalties will apply for non-compliant settings.

Updated Smart Meter Wiring Requirements

A meter installation is required to comply with the Technical Regulator Guideline - Smart Meter Minimum Technical Standard and associated Deemed to Comply Wiring Arrangements (PDF 1.1 MB).

The guideline specifies the ‘Smart Meter Minimum Technical Standard’ and the ‘Deemed to Comply Wiring Arrangements’, which is applicable to Metering Coordinators, Metering Providers and Electrical Contractors.

Recording Electrical Test Results

The Office of the Technical Regulator has developed testing and verification information to help with recording test results:

The visual inspection form, the test schedule and a copy of the eCoC are required for reconnecting the electricity supply.
