A Harmonised Downloadable File (HDF) is a record of all the meter read electricity consumption data (30-minute interval reads only) collected by the smart meter in your home. A maximum of two years’ worth of data is recorded, and you can download this file from your ESB Networks Online Account to review.

Please note, ESB Networks does not have access to a customer’s electricity tariff data, just the consumption data recorded by the smart meter in your home.  For queries relating to your electricity bill, please contact your supplier.

If you do not have a smart meter installed in your home, you will not have access to a HDF (Harmonised downloadable file). 

Please note that as part of the smart metering project, ESB Networks are currently working on making electricity consumption data available to all customers who have a smart meter installed. This service is being rolled out starting October 2022 and will take a number of months to complete.    As part of this rollout, some customers may only be able to view data from the day the update occurred on your meter. 

Your smart meter data for a maximum of the past two years is available to access on your ESB Networks Online Account.  Via your account, you can view a graphical representation of your usage and download your HDF. Please note, you must be the registered customer of the Meter Point Reference Number (MPRN) to access your smart meter data.
