How is my bill calculated?

Northern Ireland Electricity Networks (NIE Networks) read all electricity meters four times a year and send the meter readings for our customers to us. Remember, NIE Networks is a different organisation to Power NI. As an Energy Online customer you can also submit your own meter readings online, during your meter reading window.


When we receive your meter reading we work out how many units of electricity you have used since the last time your meter was read and multiply this figure by the current unit rate for your tariff. Your tariff and current unit rate can be found on Page 2 of your bill. We then deduct any discount and add VAT.


If you miss the meter reader they’ll usually provide an information card explaining what you need to do. If we don’t receive a meter reading from NIE Networks or if you miss the opportunity to submit your own meter reading during the meter reading window, we’ll estimate your bill based on your previous usage patterns.
