Meter readings 

Accuracy is everything. NIE Networks read your meter and we bill you every month or three months, depending on your tariff. If you miss the meter reader, you can still provide your readings to us directly.

Flexibility to suit your needs

We hope you’ll want to stay with us for the long-term. But our non-contracted small business customers are free to leave at any time. Not sure if you’re on the best deal? Call our Customer Helpline for advice from our energy experts.
