Finance Director – Aon Underwriting Managers (AUM)

The Finance Director – Aon Underwriting Managers (AUM) will own the Finance agenda for AUM, acting as the primary Finance business partner to the AUM CEO and leadership team. The role owns financial planning, forecasting and performance management for AUM, provides insight and challenge to drive growth, and ensures robust financial control and governance. The position has no direct reports but is supported by Aon’s Global Capability Centre (GCC), which is situated in Krakow, and operates within a centre‑of‑excellence Finance model.

A key part of the scope is the new “alignment model”, under which AUM’s revenue and costs are allocated to countries based on deal flow into AUM. This requires close collaboration with FP&A teams across multiple geographies. The role covers AUM’s footprint in London, Chelmsford and Redhill, with a hybrid working pattern.
