Routing gas underground keeps supplies protected and frees up valuable space above ground. We install underground commercial gas pipework to the required standards, managing the full process from route survey to final certification.
Our underground pipework services
- MDPE gas main installation — medium-density polyethylene mains for durable underground supply.
- Ducting & sleeving — protecting pipework where it enters buildings or crosses services.
- Electrofusion & transition fittings — robust, leak-free underground connections.
- Excavation & reinstatement — trenching, bedding, marker tape and surface reinstatement.
- Testing & certification — pressure testing and documentation on completion.
Done safely and to standard
Underground gas work requires careful planning around existing utilities and correct depth, bedding and protection. Our engineers follow IGEM and Gas Safe requirements, mark and record routes correctly, and ensure every connection is tested before commissioning.
Where it's used
Underground pipework is ideal for connecting separate buildings on a site, supplying new plant rooms, extending mains to warehouses and industrial units, or feeding external kitchens and modular buildings.

Underground works are usually combined with testing & purging and feed into a wider commercial gas installation. To connect to a live main without shutting down, see gas hot tapping.
