Commercial Manager

Commercial Manager – Major London Project

Project: Fenchurch Street

Value: £45M

Sector: Commercial (M&E – Shell & Core)

Duration: Until September 2028

Start: ASAP

This is a proper lead role on a sizeable London scheme — not a “manager in title only” situation.

You’ll take full commercial ownership of a £45M shell and core M&E package, covering mechanical, public health, and ventilation systems. You’ll lead the commercial function on the project and manage the team delivering it.

The role in a nutshell:

You’re responsible for the numbers, the contracts, and the commercial direction of the project. If it impacts margin, risk, or client position — it sits with you.

What you’ll be doing:

• Leading the commercial team on a live project
• Managing cost control, reporting, and forecasting
• Overseeing valuations, variations, and final accounts
• Taking ownership of contract administration and risk
• Working closely with the project lead to drive performance
• Acting as the key commercial point of contact

What you’ll need:

• Strong experience in a Commercial Manager / Senior QS role
• Background in M&E or building services (essential for this one)
• Proven track record leading commercial delivery on large projects
• Ability to manage both the detail and the bigger commercial picture
