Network Plus is responsible for the Mains Replacement (Repex) activity throughout Northern Gas Networks (NGN) Leeds and Cumbria operational areas.

We utilise an area-focussed project manager to ensure a continued focus on successful delivery. Each team is highly trained and capable of working across all four pressure tiers. The contract is further supported by our North West and Yorkshire regional reinstatement models and our central safety, commercial, compliance and customer teams.
