firmus energy customers have received some good news today – the price they will pay for natural gas is set to reduce.
The gas supplier will reduce tariffs in the Ten Towns Network area by 7.86% for domestic and small business customers, coming into effect from the 1st October 2025. In the ‘Ten Towns’ network, households can’t switch supplier – firmus energy is currently the only company supplying natural gas to homes.
The price cut follows a review by Northern Ireland’s Utility Regulator and will be welcomed by the 73,000 customers within the network, especially as we head into the colder months when energy use increases.
What does this mean for firmus energy customers?
For customers in the Ten Towns, this will mean the annual gas bill for a typical household with a credit meter will reduce by around £80. Customers with a prepayment meter (PaYG) will see bills reduce by around £78 per year.
Although this is the fifth decrease in prices since 2023, gas prices do remain much higher than they were back in 2020-21. Thankfully the peaks witnessed in 2022, when costs soared to around £2,350 have fallen back but prices remain volatile and above prices we would traditionally expect.
To demonstrate the volatility in cost take a look at how gas prices in the Ten Towns network have shifted over the last few years…this shows the annual cost for a typical bill pay domestic customer (using 12,000kWh per year)…
I’m a firmus energy customer…what network am I in?
With the difference in price drops by area, you may be wondering which area you fall into.
Northern Ireland is broken into three separate gas networks – these are the Greater Belfast area, the Ten Towns area and the West network area. Each is distinct and will have different suppliers, cost and tariff options.
The Ten Towns area includes:
Derry/Londonderry, Limavady, Coleraine (including Portstewart and Bushmills), Ballymoney, Ballymena (Broughshane), Antrim (including Ballyclare and Templepatrick), Craigavon (including Portadown and Lurgan), Banbridge, Newry (Warrenpoint), Armagh (Tandragee) and more than 25 other towns and villages in the surrounding area.
