Firmus Derry gas customers to receive 10% reduction for gas while oil prices soar
Firmus energy has today announced that it will be making a further reduction to its tariffs for all domestic customers living in Derry, Limavady and the rest of the ‘Ten Towns Network’ area.
The double-digit decrease will save households an average of over £92 per year.
Firmus previously lowered its gas tariff by 7.86% last October and by 11.84% in April 2025.
The new lower tariff becomes effective from 1st April 2026, and comes in contrast to soaring home heating oil prices locally following the Israel-US assault on Iran and subsequent violence in the Middle East.
Announcing this latest Firmus tariff reduction, Ryan Miskimmin, Sales Director at Firmus Energy Supply, said: “As Northern Ireland’s largest gas supplier by volume, we want to provide the best value possible to all our customers by reducing tariffs when possible.
“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.”
Karen Smyth, Director of Infrastructure and Sustainability at the Consumer Council welcomed the price reduction.
Karen Smyth said: “We welcome this gas tariff decrease from firmus energy. However, energy prices are still well above pre-pandemic levels, and the energy market continues to remain 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. We also help protect and support consumers during energy price increases.
“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.”
