Before 1 July 2015, we were required to publish a quarterly report on the number of small and large customers on market and non-market contracts.
The data used to prepare each quarterly report was collected from electricity retailers and distributors.
From time to time, retailers advised us of errors they detected in their previous reports. Rather than revising individual quarterly reports when this occurred, the time series report was kept up to date with the latest available data. Those intending to use this data should download the latest version prior to use.
