Firmus energy Supply – one of Northern Ireland’s largest suppliers of natural gas – has today [5th March 2026] announced that it will be making a further reduction to its tariffs for all domestic customers living in the ‘Ten Towns Network’ area.
Effective from 1st April 2026, this double-digit decrease will save households an average of over £92 per year. Newtownabbey-based firmus energy Supply previously lowered its gas tariff by 7.86% last October and by 11.84% in April 2025, providing significant additional savings for customers.
Announcing this latest 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.”
The Greater Belfast Network area tariff is also currently under review by the company.
