Utility Regulator welcomes decrease to energy bills


The Utility Regulator has concluded its review of the regulated tariffs for Power NI and SSE Airtricity Gas Supply. An announcement around Firmus Energy’s regulated gas tariff will be made next week. 

The review has determined that from 1 April 2024, Power NI’s domestic tariff will reduce by 6.3% or £64 per year, whilst SSE Airtricity Gas Supply’s tariff for domestic and small business customers in the Greater Belfast and West gas areas, will reduce by 22.8% or £320 per year. 

Colin Broomfield, Director of Markets, Utility Regulator, explains further: 

“In January 2024, the Utility Regulator commenced a review of Power NI’s regulated electricity tariff, and SSE Airtricity and Firmus Energy’s regulated gas tariffs. 

“Following our analysis, we have agreed that a 6.3% decrease in Power NI’s electricity tariff and a 22.8% reduction in SSE Airtricity’s regulated gas tariff will become effective from 1 April 2024. These reductions are primarily driven by the steady fall in wholesale energy prices. 

“These reductions will see a typical Power NI domestic customer paying £64 less a year. The annual bill for a typical domestic credit customer with SSE Airtricity Gas Supply will decrease by around £320 per year.”

Colin Broomfield continued: 

“While this is good news for consumers, we recognise that many households and businesses are still struggling with the cost-of-living crisis. If you are worried about paying their electricity or gas bill, help is available. We would encourage you to contact your supplier in the first instance, to make them aware of your circumstances, and discuss the options available. In addition, there are a number of agencies who can provide free and independent advice to households, including Advice NI, Christians Against Poverty, the Consumer Council and Money and Pensions Service’s MoneyHelper.

“We will continue to monitor the regulated suppliers’ tariff and will ensure any further falls in costs are passed through to customers at the earliest opportunity.” 

This tariff announcement marks the conclusion of a review undertaken by the Utility Regulator, Power NI and SSE Airtricity Gas Supply, in consultation with the Department for the Economy and the Consumer Council for Northern Ireland.
