About us
National Gas is securing Britain’s energy. We transport gas throughout Great Britain, repair and maintain gas pipelines, and manage the meters that allow millions of homes and businesses to access the energy they need. We are the national gas network, providing secure energy to power Britain, achieve net zero, and maintain our industrial competitiveness.
About the role
Keep critical energy infrastructure running safely and reliably. We’re looking for a Mechanical Technician to deliver hands-on support across compressor stations, pipelines and AGI assets.
These are predominantly pipelines-focused opportunities within our operations team, where you’ll maintain and support mechanical systems across operational gas infrastructure. You’ll carry out fault finding, repairs and performance improvement, playing a key role in both routine maintenance and emergency response.
This role provides exposure to a range of disciplines, enabling you to develop experience beyond your core specialism. This is a field-based role, working closely with technicians and wider teams to keep assets safe, compliant and performing at their best.
Why this role matters
The national transmission system underpins essential energy supply. Your work directly protects asset integrity, keeps gas flowing, and supports safe, uninterrupted operations.
You’ll take ownership of high-risk activities, support emergency response, and influence how sites operate - with real impact on safety, reliability and performance.
