Oil and GasNorthern Ireland, United Kingdom51-200 Employees

Firmus energy, based in Antrim, Northern Ireland, operates as a gas supplier and distributor within the oil and gas sector. It secured supply and distribution licenses in 2005 to develop a natural gas network outside greater Belfast. The network has since extended to a broad set of towns across Northern Ireland, expanding access to natural gas beyond the Belfast area.

It serves approximately 60,000 customers in Greater Belfast and more than 111,000 homes and businesses across Northern Ireland with natural gas, and it was licensed to supply electricity in 2009, becoming the first to offer dual-fuel contracts for large industrial customers. In 2025, the company expanded its Mallusk headquarters and was reported to be acquired by Yuno Group.
