Firmus Energy Supply announces 10.1% gas price decrease across Ten Towns Network
Firmus energy Supply has today (Thursday, March 5) announced it will be making a further reduction to tariffs for all its domestic customers living in the ‘Ten Towns Network’ area.
Effective from April 1, the double digit decrease will save households an average of over £92 per year. The Newtownabbey-based natural gas supplier previously lowered its tariff by 7.86% last October and by 11.84% in April 2025.
Announcing this latest tariff reduction, Ryan Miskimmin, sales director at firmus energy Supply, said: “This is our third consecutive tariff reduction for the Ten Towns Network in the space of a 13-month period.
"This latest reduction of 10.1%, which follows engagement with the Utility Regulator and the Consumer Council, is sure to be welcomed by our growing number of customers who have made the switch to natural gas.
“Since April last year, our consecutive reductions have decreased our tariffs by 27% with a cumulative saving of around £300 per customer. We know that these savings, coupled with the constant heat and instant hot water that natural gas provides, will be warmly welcomed by customers in the Ten Towns Network.”
The Ten Towns Network area includes Antrim, Armagh, Ballymena, Ballymoney, Banbridge, Coleraine, Craigavon (including Lurgan and Portadown), Limavady, Derry/Londonderry, Newry and more than 25 other towns and villages in the surrounding areas.
The Utility Regulator confirmed its review of the regulated gas tariff for firmus Energy in the Ten Towns area has concluded.
Colin Broomfield, director of markets at the Utility Regulator said: “In early February 2026, we began a formal review of the regulated tariff for domestic and small business gas customers of firmus energy.
“Our analysis has resulted in a 10.1%, or £94 per year, decrease to the regulated tariff for domestic and small business customers in the Ten Towns area. The decrease will come into effect on 1 April 2026. This follows on from the announcement last week that SSE Airtricity Gas Supply’s regulated tariff is reducing by 8.1% or £80 per year.
“The reasons for this reduction to firmus energy’s regulated gas tariff is due to a fall in wholesale gas costs and an over-recovery being returned to customers.
“Both tariff reviews were completed before the recent conflict in the Middle East began. The conflict has impacted gas prices globally, which have risen sharply over the last few days. We expect that wholesale gas prices will remain volatile while the conflict continues. We will continue to monitor the regulated tariffs over the coming weeks.”
Meanwhile, the Greater Belfast Network area tariff is also currently under review by firmus energy Supply. The area covers Belfast, Lisburn, Bangor, Holywood, Donaghadee, Groomsport, Millisle, Newtownards, Carryduff, Comber, Newtownabbey, Carrickfergus, Larne, and east Down.
