Site Agent / Senior Site Agent

Contract | Outside IR35 | £400–£425 per day | South East England (Surrey area)

We’re looking for a Site Agent or Senior Site Agent to take charge on major wastewater treatment projects within a long-running regulated water framework: valued at £15M+. In pre-construction and early contractor involvement now, with main works set to begin early next year. You’ll be on the ground early enough to influence how they’re built.

The Opportunity

You’ll be the site lead from first principles through to completion. That means:

• Shaping the early stages alongside the Project Manager and Senior Project Manager, supporting planning and documentation through de-risking, ECI, ecology and trial holes
• Leading enabling works and welfare setup, then running day-to-day operations through the full construction phase
• Coordinating civils, mechanical, electrical and ICA (MEICA) works across multiple disciplines on technically demanding sites
• Owning the standards: Health, Safety, Environmental and Quality compliance, plus the Construction Phase Plan and Environmental Plan
• Driving subcontractor performance and keeping clients, supply chain and internal teams aligned
• Working safely around live services, where your judgement matters most

What You’ll Bring

• A proven track record as a Site Agent or Senior Site Agent on water or wastewater infrastructure
• Experience leading subcontractors and multidisciplinary teams on projects of £15M+
• A strong grasp of Tier 1 contractor processes and the paperwork rigour that comes with them
• Knowledge of civils reinstatement works
• Confidence and competence operating around live services
• SMSTS, CSCS (appropriate to your level) and First Aid; Temporary Works Coordinator or Supervisor is a bonus

Water sector experience is preferred but not essential. If you’re a Tier 1 operator with the process discipline and safety mindset to match, we want to hear from you.

The Package

• Rate - £400–£425 per day
• IR35 status - Outside IR35 (subject to assessment)
• Duration - 24 months plus
• Hours - Monday to Friday, site hours 07:30–17:30
• Base - Fully site-based, 5 days a week

High-value work with a framework client who takes safety seriously. The client runs robust HSE processes to protect everyone on site, and you’ll be working with people who share that commitment.

A Quick Note on the Role

This is a hands-on, on-site position, so you’ll always be on a working site or hub, never behind a desk.
