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.

Great customer service

Our customer service advisors in our local contact centres offer fast and friendly advice. They aim to answer 90% of calls within 20 seconds.

Championing customer service

What really matters to us is the great service we offer. For nine years, we’ve been proud to have the lowest level of complaints out of all the energy suppliers in Northern Ireland!*
