Your HDF (Harmonised Downloadable File) holds every 30-minute reading from your smart meter. It lets us price your real usage instead of guessing, and takes a couple of minutes to get once your account is set up.
Step 1
Create an ESB Networks account
Go to esbnetworks.ie and register for an online account with your email. You will need your MPRN, the 11-digit number printed on your electricity bill.

Step 4
Upload it to EnergyPal
Drop the CSV onto the upload box on our homepage. We price your real usage against every current plan in a few seconds.
Tip
Download the longest date range available. A full 12 months captures winter heating and summer solar, so the ranking reflects your whole year.
