Jon is a forensic accountant and Associate Director in Control Risks’ forensic investigations practice in Europe, the Middle East and Africa. Based in London, Jon works primarily on managing complex fraud, misconduct and accounting mis-statement investigations but also has extensive experience in responding to regulatory inquiries and helping businesses manage their fraud risks proactively.

Jon’s recent projects include: 

  • Managing an accounting misstatement and fraud investigation at a large international food business. The investigation focussed on the conduct of 27 individuals and resulted in uncovering over £100m of inaccuracies within the Balance Sheet.
  • Investigating supplier fraud within a construction business, uncovering collusion between members of staff and external suppliers to create fake invoices and make payments for work not done, resulting in the business recovering a significant proportion of the funds lost.
  • Leading a review of the accounting practices of a high-street restaurant chain, conducting interviews with members of the team, establishing the areas which appeared to have been misstated and recalculating the true values to be reported in the financial statements.
  • Acting as a consultant to one of the “big four” banks to redesign their end-to-end investigations process following criticism from their regulator. This included conducting interviews with internal stakeholders to understand the current process, proposing improvements, and drafting a new guide to conducting investigations at the bank.
  • Directing a review into disbursements from a fund managed by a fast-food business for the benefit of its franchisees. His role was to facilitate the franchisees’ understanding of the mechanisms used to make charges to the fund and to highlight irregular payments.

  • Jon has been involved in investigations across the UK and Europe, working with regulators, external legal counsel, law enforcement and internal investigation and compliance teams. Before joining Control Risks, Jon worked in the forensics department of a “Big Four” firm for over nine years. 

    Jon holds a bachelor’s degree in Mathematics from the University of Nottingham and is a member of the Institute of Chartered Accountants in England & Wales (ICAEW). He is also an Accredited Counter Fraud Specialist (ACFS).
