Utility Regulator comments on decrease to Firmus Energy’s regulated gas tariff

Commenting on Firmus Energy’s regulated tariff announcement, Colin Broomfield, Director of Markets at the Utility Regulator said: 

“In January 2024, the Utility Regulator commenced a review of Firmus Energy’s regulated gas tariff for domestic and small business customers in the Ten Towns area. Following our analysis, the review has determined that from 1 April 2024, Firmus Energy’s regulated tariff will reduce by 15.6%, or £213 per year. This reduction is primarily driven by the steady fall in wholesale energy prices. 

“This decrease to Firmus Energy’s regulated gas tariff is good news for consumers and follows the announcements made last week regarding decreases to the regulated tariffs of Power NI and SSE Airtricity Gas Supply. This means that regulated electricity and gas tariffs in Northern Ireland will compare as follows to Great Britain and the Republic of Ireland:

Average annual bills from 1 April 2024

Power NI (electricity) and SSE Airtricity (gas, Greater Belfast and West)

Power NI (electricity) and Firmus Energy (gas, Ten Towns)

Great Britain

















Note: Figures above based on the annual bill of a domestic customer consuming 12,000 kWh of gas and 3,200 kWh of electricity on the standard tariff. [i]Exchange rate of 0.85 used.

“We welcome these recent decreases to electricity and gas bills, however we recognise that many households and businesses are still struggling with the cost-of-living crisis. If you are worried about paying your 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.

“Tariff reviews form part of our regular scrutiny to make sure that consumer bills reflect the actual cost of providing gas to homes and businesses. We will continue to monitor the regulated suppliers’ tariffs and 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 and Firmus Energy, in consultation with the Department for the Economy and the Consumer Council for Northern Ireland. 

A briefing paper for the Firmus Energy tariff review has been published.
