Frequently Asked Questions

The Estimated Annual Bill (EAB) is a simple indicator of the cost of electricity for an average household for one year and allows the consumer to compare prices between electricity suppliers.
The EAB includes VAT and all energy related charges such as the Standing Charge and Public Service Obligations (PSO) Levy. The EAB also takes into account the following information;

    • Is your meter Urban or Rural?
    • Is your meter 24 Hour or Day/Night?
    • Do you have Night Storage Heating?

The EAB does not include non-energy related items such as credits for switching, loyalty points or non-cash offers.
The EAB is based on expected average electricity consumption for one year. The average consumption figure is approved and published by the Commission for the Regulation of Utilities (CRU). Currently, the value for estimate annual average consumption for electricity is 4,200 kWh.
CRU has asked all suppliers to provide an estimated annual bill and mandated that Suppliers use industry average annual consumption figures as published by them, when calculating the EAB.
Please note that your actual annual consumption may vary from these figures so your actual bill may be higher or lower than the EAB stated.

Your MPRN is your Meter Point Reference Number.

The MPRN is a unique 11 digit number specific to the Meter at the property.

The MPRN can be found on the top right hand of your electricity bill.

If you have moved to an existing property, the previous owner or landlord can provide you with the MPRN number.

If you have moved to a new house, contact ESB Networks on 1850 372757 and they will verify your MPRN number.

Your electricity meter counts the units of electricity you use which are measured in kWh (kilowatt hours).

To read your meter record the numbers on the display from left to right including any zeros and ignore any numbers in red or any numbers surrounded by a red box.

If there is only one display on your meter then you have a 24 Hour Meter.

If there are two displays you have a Day/Night Meter and you must record both numbers.

Meter readings keep your bill accurate – by submitting monthly meter readings you ensure you only pay for what you use. Email with your monthly meter reading and we will keep your bill as accurate as possible.
