My meter has already been read by Airtricity. Why does NIE need to read it too?
Your new supplier may take a one-off meter read to facilitate switching suppliers. This is so that it can calculate your opening bill and so your former supplier can calculate your closing bill. From then on, NIE will continue to read your meter on a scheduled (quarterly) basis and pass this information onto your new supplier. Additionally, your new supplier will accept meter reads provided by you at any time between scheduled meter reads.
