In this role you will support operational and strategic decision-making across installation projects, service contracts, and maintenance activities, while ensuring robust reporting, governance, and scalable finance processes.

This is a hands-on leadership role suited to a commercially minded finance professional who can both run an effective control function and influence performance across the wider business.

This role is a full time permanent role, based from our Abingdon office on a hybrid basis. The role will also involve some occasional travel.

• Drive visibility of project margins, job costing, and contract performance to enable timely interventions

• Identify and deliver margin improvement, cost efficiency, and working capital opportunities

What we're looking for:

• Significant experience in a senior finance leadership role

• Ability to influence and challenge senior stakeholders constructively

• Confident communicator with the ability to explain financial concepts clearly

• An analytical and insight-driven leader, with a focus on outcomes

• Resilience and adaptability in a fast-paced, evolving environment

• High integrity and ownership mindset

• Experience partnering with operational or project-based businesses such as construction, engineering, facilities management, or fire & security services is highly desirable

What we can offer:
