Power NI announces 4% electricity tariff increase amid rising costs

Northern Ireland’s largest electricity supplier, Power NI, has confirmed a 4% increase in its residential electricity tariff, effective from 1 October 2025.

The announcement, made on 5 September, will see the average household pay an additional 11 pence per day, equating to approximately £40 more per year for credit meter customers and £39 for those using pay-as-you-go (PAYG) keypad meters.

The tariff adjustment, approved by the Utility Regulator, reflects rising market operation and network-related charges beyond the supplier’s control.

Power NI, the only price-controlled electricity supplier in Northern Ireland, serves over 500,000 households.

The company stressed that the decision to raise tariffs was not taken lightly. William Steele, Director of Power NI Customer Solutions, explained:

“We work hard to keep our prices as low as possible. Even though we have seen wholesale energy prices stabilise, they remain higher than previous years. Unfortunately, rising regulated pass-through market and network related costs which are beyond our control, have made a tariff adjustment unavoidable.”

This marks the second tariff increase by Power NI in less than a year, a development that has raised concerns among consumers already grappling with cost-of-living pressures.

Raymond Gormley, Head of Energy Policy at The Consumer Council, noted:

“From October, over 500,000 homes in Northern Ireland will see their annual electricity cost increase to around £1,029 for a typical credit customer and increase to around £1,003 a year for a typical keypad customer. While this is unwelcome news for consumers, we are aware the main drivers for this are increases in market operation and network related charges.”

Support and savings options for C

customers

Power NI has emphasised its commitment to supporting customers through this price adjustment. The company offers a range of discounted payment schemes to help mitigate the impact.

For instance, customers who opt for online billing and monthly Direct Debit can save up to £60 annually. Pay-as-you-go keypad customers can benefit from uncapped discounts and free electricity when topping up £50 or more via the Power NI app or website.

“We value our customers, and we are continuing to work closely with our charity partners and other organisations across our local communities to provide support to those in need,” said William Steele.

“We have a range of assistance available, from tailored tariff guidance to energy-saving advice and account support, so if you’re concerned about managing your bills, please reach out to us – we’re here to help.”

Customers can top up their accounts conveniently through Power NI’s free app, online platform, or 24/7 automated payment line at 08000 285 455. Further details on available support and savings options are accessible at www.powerni.co.uk/pricing.

Consumer Council urges action

The Consumer Council has urged households to explore ways to reduce their energy costs in light of the tariff hike. Raymond Gormley advised:

“We would encourage consumers to think about the way they pay for their energy and see if they can reduce their energy costs. Being on a standard tariff and paying on receipt of a bill is the most expensive way to pay for your electricity.

“By switching payment option, changing billing method or even switching supplier may save you money.”

The Consumer Council provides a free, independent energy price comparison tool on its website, enabling consumers to compare electricity and gas tariffs across Northern Ireland.

Gormley also highlighted the importance of timely cost savings:

“The Consumer Council works closely with the Utility Regulator and regulated supply companies to ensure consumers are protected and supported during price increases. We ensure that any cost savings are passed onto consumers quickly when wholesale energy prices or network-related costs begin to decrease.”

A regulated approach to pricing

As Northern Ireland’s only price-controlled electricity supplier, Power NI’s tariffs are subject to a regulatory formula overseen by the Utility Regulator. This ensures that all costs are scrutinised and approved, providing customers with confidence in the fairness of pricing.

Despite the increase, Power NI maintains that its tariffs remain competitive compared to equivalent averages in Great Britain and the Republic of Ireland.

The tariff adjustment applies solely to domestic customers, with the 4% increase specifically affecting Power NI’s Home Energy customers, though other preserved tariffs may vary.

The average additional cost of 11p per day is based on a standard Home Energy rate and typical household usage of 3,200 units (kWh) per year.

Looking ahead

As households prepare for the tariff increase, both Power NI and the Consumer Council are encouraging proactive steps to manage energy costs. From exploring discounted payment plans to seeking tailored advice, consumers have options to cushion the impact of the price rise.

With energy costs remaining a significant concern for many, the focus on support and transparency from both the supplier and regulator will be crucial in navigating these challenging times.
