You’ll be part of a skilled operations team, carrying out daily and weekly site tasks, supporting planned and statutory maintenance, diagnosing faults, and contributing to more complex project work across our biomethane assets.

SGN Green Gas Solutions is a wholly owned subsidiary of SGN. We own and operate several biomethane gas clean‑up plants and network entry facilities, and we also provide operational and maintenance services to third‑party sites.

We deliver safety, warmth, and comfort to homes and businesses. Every role, whether in the office or on the front line, plays a key part in this mission. Here’s how you will contribute…
