Sub Agent – Water Infrastructure
Surrey | Contract | Up to £380 per day | IR35 TBC
The Project
A significant water infrastructure programme delivering major upgrades across treatment and network assets across Surrey, the kind of project where a capable Sub Agent can make a real difference and build a strong long-term relationship with a contractor who has plenty of work ahead.
The Role
As Sub Agent you will sit between the site management team and the engineering function, taking ownership of day-to-day delivery across your work packages, coordinating site teams, managing subcontractors, driving programme, and ensuring quality and safety standards are maintained throughout. You will be trusted to run your section with a degree of autonomy.
This is the right role for someone who is ready to step beyond pure engineering and take genuine management responsibility or for an experienced Sub Agent who wants to be part of a well-structured, properly resourced scheme rather than being spread too thin.
