Function: Commercial
Coverage: UK/ West Europe
Projects Portfolio
Reports to: Commercial Director / Business Controller Pre-Fab and Installation
Direct / Functional Reports: Commercial Managers, Managing Quantity Surveyors, Quantity Surveyors, Change Managers, and associated commercial resources
Role Purpose
The Head of Commercial is responsible for providing strategic commercial and contractual leadership across the projects portfolio, with primary accountability for margin protection, commercial governance, contractual strategy, financial assurance, risk management, and commercial performance.
Operating as the senior commercial authority for Projects, the role provides expert leadership throughout the complete project lifecycle — from tender and contract negotiation through project execution, change, claims, recovery, dispute resolution, and final account.
The Head of Commercial acts as the principal escalation point for significant commercial and contractual matters and provides direct intervention on projects requiring special measures due to deteriorating margin, programme delay, significant change, contractual dispute, cash exposure, or other material commercial risk.
A fundamental requirement of the role is extensive contractual knowledge and the ability to understand, interpret, articulate, present, and negotiate complex contractual positions, translating contractual provisions into practical strategies that protect the Company’s entitlement and financial performance.
The role provides independent commercial challenge to project teams and senior management, ensuring that reported project performance is evidence-based, contractual rights are preserved, and commercial risks are identified and addressed before they crystallize into financial loss.
The Head of Commercial also owns the development and consistent application of commercial standards across Projects, including CVR, forecasting, contract administration, commercial assurance, claims management, tender governance, and commercial capability development.

Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
