Ambit is a leading specialist delivering high-quality commercial fit-out, refurbishment, and complex cut & carve projects across London and the UK. As part of the Workplace Futures Group, we combine technical excellence with forward-thinking design to transform existing buildings into high-performing, future-ready spaces.
We are seeking a Project Commercial Manager (Quantity Surveyor) with proven experience in refurbishment, retrofit, and cut & carve environments, where complexity, risk, and technical understanding are critical to success.
The Role
You will take ownership of the commercial delivery of projects that involve working within and transforming existing structures — often in live environments, constrained sites, and technically challenging conditions.
This is a role for a commercially astute professional who understands the nuances of refurbishment and cut & carve delivery, from managing unknowns and risk to driving value through strong procurement and cost control.

- Develop and manage cost plans, budgets, and financial reporting aligned to complex project conditions
- Drive procurement strategies suited to phased works, specialist packages, and constrained environments
- Manage and administer valuations, variations, and change control, including managing design development impacts
- Identify and mitigate commercial risks associated with existing buildings, including surveys, unknown conditions, and structural interfaces
- Work closely with project and site teams to align construction sequencing, programme, and commercial planning
- Administer contracts (typically JCT), ensuring robust commercial protection in complex delivery scenarios
- Manage subcontractor performance, ensuring value, compliance, and cost certainty
- Lead on final accounts, ensuring timely and commercially favourable close-out
Required Experience & Skills

- Someone confident managing uncertainty, change, and evolving design information
- Strong communicator able to work across technical and non-technical stakeholders
- Detail-oriented, proactive, and capable of delivering in a fast-paced, high-expectation environment
- A team player aligned to Ambit’s values of quality, collaboration, and excellence
