Measuring retail market performance

Retailers are required to regularly report a series of metrics to us related to their performance, including customer numbers, contract types, complaints, energy debt, payment plans, hardship programs, disconnections and reconnections.

We publish this data on a quarterly and annual basis and provide commentary and analysis that contributes to understanding and decision-making in the retail markets.  

Our performance reporting procedures and guideline (2019) assist retailers to know what data is required to be sent to us at regular intervals.
