Firmus Energy will lower gas tariffs by 10.1% for domestic and small business customers in Northern Ireland's Ten Towns Network area. The reduction equals a £94 yearly saving on average and starts April 1, 2026. The Utility Regulator approved the change after a review launched in early February 2026.

Lower wholesale gas costs and return of over-recovered amounts to customers drove the tariff cut. Colin Broomfield, director of markets at the Utility Regulator, said the review finished before recent Middle East conflict raised global gas prices. He expects wholesale prices to stay volatile and plans ongoing monitoring of regulated tariffs.

This marks the third tariff reduction for Ten Towns customers in 13 months. Ryan Miskimmin, sales director at Firmus Energy, said tariffs fell 27% since April 2025, for total savings of about £300 per customer. The company now reviews tariffs for the Greater Belfast Network area.

The Utility Regulator noted last week's 8.1% cut, or £80 yearly, to SSE Airtricity Gas Supply's regulated tariff. Broomfield advised customers facing payment issues to contact suppliers first. He listed Advice NI, Christians Against Poverty, the Consumer Council, and MoneyHelper as sources of free advice.
