We issue you a bill on the same day every month/2 months; As your meter is only read up to 4 times a year by the meter operator (NIE T&D), we have to estimate your consumption to ensure that you get your bill when you expect it.

Sometimes we will have an actual meter read but your bill may also contain some estimation. This is because we issue your bill on the same date every month/2 months and the read mightn't cover the full billing period. We’ll estimate your consumption from the actual meter read date to the end of your billing period.

This does not apply to Max Demand or Interval customers as your bills are not estimated.
