Power NI

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. It supplies electricity to more than 500,000 customers, but doesn't provide gas.

Power NI has maintained a lot of its market share since competition was introduced from energy companies such as Budget Energy and SSE Airtricity. It still supplies just under 60% of the domestic market.

It says that it offers ‘excellent customer service’. It gives customers advice on energy-saving measures, and also installs them. Power NI says it's committed to community work, supporting local organisations and charities.

Which? verdict on Power NI

Power NI's rating is pretty middle-of-the-road - it sits in third place in the table of six Northern Ireland energy firms. 

Customers gave Power NI four stars out of five for its bill accuracy, with 87% of respondents saying it's good or excellent. This is impressive, but also in line with most of the other NI firms in the survey. 

It got three stars out of five for bill clarity, customer service, dealing with complaints, digital tools, and value for money. 

The one area in which customers were least positive about Power NI was how it deals with complaints. 12% of respondents rated it poor or very poor in this area, which is marginally the highest proportion compared with the other NI suppliers we have ratings for.

Power NI offers a choice of tariffs, including online-only tariffs and monthly or quarterly direct debit bills.

The firm also claims to be the UK leader in pay-as-you-go keypad metering (when customers top up their energy credit as they would a mobile phone).

Power NI has a customer reward scheme called Perks, which offers cashback and discounts with certain brands.

Pros: A well-established company whose customers find its bills accurate

Cons: Only provides electricity, some customers are unhappy with the way it deals with complaints
