Our core services

Insurance and risk management

Insurance and risk management is the cornerstone of every company's capital structure. A poorly constructed programme leaves an organisation vulnerable to major risks, while a well-designed one frees a company to pursue its vision without having to hoard financial capital or maintain unusually high levels of liquidity.

Human Capital

Aon Hewitt is a global leader in providing employee benefit consulting and benefit solutions that deliver long-term value to clients of all sizes, across all industries. Experts deliver market-leading pensions administration and consulting, as well as employee benefits programmes and cost-effective, efficient HR solutions.


Reinsurance is critical to helping insurance companies underwrite risk profitably. Aon Benfield, the world's leading reinsurance broker and intermediary, provides clients with integrated capital solutions and services. These are delivered to agents, brokers, associations, affinity groups and individual customers, as well as companies of all sizes, through Aon's global network of local resources.
