Job description

Interim Head of FP&A | London | c.£800-£1,000/day (Outside IR35)

A newly appointed CFO for an established business in the insurance sector is building out the FP&A function from the ground up as they look to professionalise their finance function. We're looking for an interim leader to help shape it.

This is a rare "blank page" interim mandate. You won't be maintaining an existing function — you'll be building one, working directly with the CFO to design how FP&A operates, reports, and adds value across the business.

What you'll be doing:

• Building out the FP&A function from scratch, reporting directly into a newly appointed CFO
• Designing and implementing MI/management reporting frameworks where none currently exist
• Supporting the finance workstream of an ongoing Workday implementation
• Partnering closely with the CFO to shape the function's structure, processes, and priorities
• Bringing best-practice FP&A thinking into an organisation ready to invest in it

What we're looking for:

• A hands‑on interim FP&A leader with a track record of building or transforming finance functions
• Experience working in insurance - strong capital management and and understanding of underwriting processes.
• Experience implementing or supporting Workday (Finance/Adaptive) strongly preferred
• Comfortable operating at pace in a "zero to one" environment with high visibility to the CFO
