Metering Code

The Electricity Industry (Metering) Code 2012 provides information on the rights, obligations and responsibilities of Code participants. It outlines rules for providing metering installations at connection points, metering services, standing data and energy data.

Metering Code Model Service Level Agreement (SLA)

We provide metering services to electricity retailers in accordance with the Metering Code Model* Service Level Agreement (SLA). The SLA includes information on the costs and timeframes of metering work and services – including scheduled and off-cycle meter reading, electricity meter upgrades and installations, retailer credit management and the provision of metering data for these tasks.

The SLA also relates to the Electricity Industry (Metering) Code 2012 by detailing how we and electricity retailers meet Code obligations.

*Applicable to retailers where no other agreement is current.
