Simon Sheaf (General Insurance Actuarial Practice Leader)

I have worked in, and consulted to, the general insurance industry for nearly 25 years.  I focus on the provision of practical advice to enable clients to make informed management decisions in financial and operational matters. Prior to joining Grant Thornton in 2006, I was the Chief Actuary at a general insurance company.

My extensive experience in the general insurance sector includes the following:

  • Establishing and leading in-house actuarial functions
  • Solvency II
  • Developing capital models
  • Estimating claims reserves
  • Pricing of portfolios and individual risks
  • Fulfilling the role of the Independent Expert on Part VII transfers
  • Section 166 Skilled Person reviews
  • Actuarial due diligence for mergers and acquisitions
  • Fulfilling the role of the Scheme Actuary on Schemes of Arrangement
  • Developing and implementing management information systems
  • Providing advice and guidance to boards and senior management teams

I currently sit on both the Council and the Management Board of the Institute and Faculty of Actuaries. I am also a member of the Institute and Faculty of Actuaries' General Insurance Board. In addition, I was formerly Chairman of the Institute and Faculty of Actuaries' General Insurance Education and CPD Committee and am a former member of its Education Board , Education Committee, and General Insurance Reserving Oversight Committee.

I am happily married. I used to have hobbies but now I have two daughters instead!
