Accessing your metering data
You or an authorised third party can request up to two years of metering data for your premises. You must have been the electricity account holder for the period for which you request data.
Types of data available
We can provide quarterly summary metering data or monthly detailed metering data, depending on the type of meter at the premises.
Please note: Data is available from 1 January 2007.
Quarterly summary data
If you have an accumulation meter (i.e. a meter which is read by our meter readers each quarter), a summary of quarterly metering data will be provided as a PDF file via email or post. To find out more about reading the summary data, please see Understanding your site consumption report – Accumulation metering data (PDF 347.9 kb).
Monthly detailed data
If you have an interval meter (i.e. an electronic device that records your electricity use every 30 minutes and which is collected daily via remote communication), detailed monthly data will be provided as a CSV file via email only. To find out more about reading the detailed data, please see Understanding your site consumption report – Interval metering data (PDF 293.3 kb).
Daily detailed data
If you have an electronic basic accumulation meter, data broken down to 30-minute intervals may be available for a further fee. The availability of this data depends on your meter type and a list is provided in our Guide to Meter Types for Daily Data (PDF 569.6 kb). Detailed daily data will be provided as an Excel file (xlsx) via email only. To find out more about reading the daily data, please see How to interpret a daily data report (PDF 778.2 kb).
The data is usually free of charge, but fees may apply if you request data:
- More than four times in any twelve month period
- In a different format to that specified above
- Which is more than two years old.
For charges refer to Alternative Control Services.
