Gas price decrease across Ten Towns Network announced by firmus energy
Firmus energy has today (Thursday, September 4) announced it will be making a further reduction to its tariffs for all domestic customers in the Ten Towns Network area.
Effective from 1st October 2025, the decrease will save households an average of £78 per year. The company previously lowered its gas tariff by 11.84% in April.
Ryan Miskimmin, sales director at firmus energy Supply, said: “We are pleased to share our second tariff reduction of the year and are always committed to passing on any savings to customers, whenever it is possible for us to do so. Having engaged with the Utility Regulator, and Consumer Council, we are able to announce this reduction of 7.86 %.
“Since April this year, our consecutive reductions have decreased our tariffs by almost 19%, representing an average household saving of £210 per year. As we head into the colder months, we know that these savings coupled with the constant heat and instant hot water that natural gas provides, will be welcomed by Ten Towns customers.”


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.
An announcement regarding the Greater Belfast Network area will be made in the coming weeks. It covers Belfast, Lisburn, Bangor, Holywood, Donaghadee, Groomsport, Millisle, Newtownards, Carryduff, Comber, Newtownabbey, Carrickfergus, Larne, and East Down.

The Consumer Council has welcomed the tariff reduction announcement.
Karen Smyth, director of Infrastructure and Sustainability at the independent consumer organisation, said: “We welcome this gas tariff decrease from firmus energy, as it indicates a slight downward curve in wholesale energy prices. However, energy prices are still well above pre-pandemic levels, and the energy market continues to remain very volatile due to ongoing global geopolitical concerns.
“The Consumer Council works closely with the Utility Regulator and regulated supply companies to ensure that any cost savings are passed onto consumers quickly when wholesale energy prices begin to decrease and we also help protect and support consumers during energy price increases.
“We know from our ongoing research that most consumers in Northern Ireland are still really worried about home energy prices. We urge anyone who is struggling to pay their energy bills or top-up their meters to contact their supplier directly as suppliers have indicated that they are keen to offer their customers help and support.”
