Understanding your bill

We know that many customers find it difficult to understand their electricity bills. This guide helps to explain some of the important pieces of information on your bill.

Suppliers must include certain information on your electricity bill to make it clear and easy to understand. Not all suppliers’ bills will have the information in the same place as this sample bill.

The front page

On the front page of your bill you will usually find:

Account details

Account number

This is the number for your account with your supplier. You should always reference it when talking to them.

Emergency phone number

Your electricity bill will always show ESB Network's emergency contact number.


This is the address the bill is sent to. It may not be the address where the energy used is being billed for.


Your Meter Point Reference Number (MPRN) is the unique code for your connection to the electricity network. You need this to switch suppliers or if you have a query with ESB Networks.

Billing period
