Request up to the last 24 months of your electricity consumption data (i.e. the amount of power you used). This information can help you understand your electricity usage habits and make informed decisions when choosing a power plan for your household.

Choose to request either:

  • a summarised report - the consumption data recorded on each of your bills, or
  • a detailed report - the consumption data in its most detailed format

The amount of data provided will depend on the period you are requesting for, the type of meter, and how often the meter was read, e.g. if you have a smart meter, your data may include 15-minute interval readings. We recommend requesting a summarised report due to the volume of information you could receive in a detailed report.

Request consumption data or contact Mercury online.
