Gas mains replacement

At Prestige Pipelaying JV Ltd, we specialise in the safe and efficient renewal of gas mains, working in partnership with the UK Gas Distribution Networks, and other major utility providers. We deliver over 100km of gas mains replacement each year, helping maintain and future-proof the UK’s gas network for homes and businesses.

Gas Infrastructure

Our approach

We follow a structured process to ensure every project meets the highest standards of safety, quality, and compliance.

Planning and risk assessment

Every job starts with a full site review.
We assess utility drawings, identify hazards, and carry out detailed risk assessments to establish safe systems of work before breaking ground.

Excavation and pipeline exposure

Our teams use industry-approved methods to expose existing mains safely while keeping disruption low.
Where required, we install trench support systems to maintain safety and stability.

Installation of new mains

We replace aging assets with durable polyethylene (PE) pipes, known for strength and corrosion resistance.
Depending on the site, we use trenchless methods such as directional drilling, insertion, or Moling to minimise excavation and public impact.

PE pipe jointing and testing

All pipe connections are completed using electrofusion or butt fusion techniques for strong, leak-free joints.
We then perform pressure testing with calibrated gauges to verify integrity and compliance with industry standards.

Service transfers and reinstatement

After testing, we transfer all services to the new main and reinstate roads, footpaths, and private land in line with NRSWA requirements.

Gas Infrastructure

Gas diversions

We carry out complex gas diversions for infrastructure and development projects.

Our teams are skilled in multiple laying techniques – Open Cut, Insertion, Mole Ploughing, and Horizontal Directional Drilling (HDD) – covering mains from 32mm to 355mm in diameter across Low, Medium, and Intermediate pressures.

We manage all connection types including Bag Stop, Squeeze Off, UPT, Branch Saddle, Stopple, and Valve Connections.
