What tariff am I on?

Q: 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. 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 (for example if you pay by Direct Debit) 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, we’ll estimate your bill based on your previous usage patterns. Find out how/if your bill is estimated

Q: How do I know which tariff my bills are based on?

Your tariff is shown on the top right of page 1 of your bill. For more information on how to understand your bill, visit our bills & payments section .

Q: Can I change tariff?

For premises with standard meters we’ll need to change your meter to change your tariff. The supply will need to be interrupted for a short period. If it can be done during normal working hours it’s free of charge. All we ask is that you give your new tariff a real chance to save you money and stick with it for a full year. After this time you can switch back again, free of charge. A fee applies for installing a half-hour meter.
