Our Culture

Founded in 2005, firmus energy is responsible for the construction and operation of the natural gas network outside Greater Belfast (from L’Derry to Ballymena and from Antrim to Newry), providing safe, cheaper, practical and environmentally-friendly natural gas to homes and businesses. We supply over 50,000 customers across our licensed area, and also compete in the natural gas market in Greater Belfast, where we supply over 50,000 customers. We love protecting the environment. We have displaced over 1 million tonnes in carbon emissions. That’s the same as taking 40,000 cars off the road. We have been building out our natural gas network since 2006 and in that time have laid approximately 1,700km of gas mains to bring a safe, affordable home heating alternative. That’s like travelling from our Antrim offices to Frankfurt as the crow flies. Important information for candidates: firmus energy use reserve lists for positions where more than one candidate is deemed suitable for a position. Reserve lists are in place for 12 months during which reserve candidates will be offered the same or similar post should one become available during this time. Specific Purpose (temporary) Contracts only: Should a permanent vacancy arise during the course of a Specific Purpose / temporary Contract, the successful candidate will be offered the position on a permanent basis subject to pre-specified conditions.
We work hard to create a culture where people feel valued and where their contribution matters. We always strive to live out our values by behaving with integrity, empathy, clarity and teamwork. We have fun too. We care about what our staff think and have an array of communication channels including our ‘MD Talkback’ where staff get to ask our MD anything they like! And our ‘Right Track’ committee enables employees to make suggestions for improvements across the organisation. We also care about the physical and mental health of our people and hold many wellbeing initiatives as well as staff events. We offer several benefits such as private medical insurance, performance related pay, generous annual leave, life assurance, income protection, enhanced parental pay, gym subsidies, free parking and much more.
