Power NI

Power NI is the biggest electricity retailer in Northern Ireland, and has been running for more than 80 years. We reveal whether it's any good.
Tom Morgan

Power NI is part of Energia Group, an Ireland-based energy company that generates power in coal and gas-fired power stations, plus wind farms. The company, which has supplied electricity in Northern Ireland for over 80 years, serves more than 500,000 customers. Note that Power NI doesn't supply gas at this time.

The energy supplier has maintained a lot of its market share since competition was introduced from energy companies such as Budget Energy and SSE Airtricity. According to the group's website, Power NI is currently fulfilling 62% of the domestic market’s electricity needs and 48% of the commercial market.

Power NI is convinced that it offers ‘excellent customer service’, claiming that unlike other suppliers, it doesn't lock customers into a fixed contract. It also promises that its users won't be stung by hidden fees.

The company says it's committed to community work, supporting local organisations and charities.

I've never noticed any discrepancies.

However, the energy supplier scored three stars for bill clarity, suggesting there's still room for improvement when it comes to communication with customers. Some respondents described their bills as 'confusing' or 'complicated'.

In our latest Which? customer satisfaction survey, Power NI got three stars out of five for customer service, dealing with complaints and overall value for money. 

Responses were fairly mixed on the subject of costs – while some customers praised 'competitive pricing', others told us their plan is 'too expensive'. Power NI offers a choice of tariffs, including online-only tariffs and monthly or quarterly direct debit bills.

It's too expensive.

Five stars for value for money because they're competitive on pricing.
