Qualifications and Professional Memberships

Rob qualified as a Chartered Accountant with the Institute of Chartered Accountants in England and Wales (ICAEW) in 2004, having completed his professional training at Edwards Veeder Chartered Accountants.

He holds Fellowship of the ICAEW (FCA) and is a Member of the Academy of Experts (MAE), one of the UK’s leading professional bodies for expert witnesses.

Rob is also a Certified Cryptocurrency Investigator and a member of the Network of Independent Forensic Accountants (NIFA).

Career Background

Rob began his forensic accounting career in 2004 at Ernst & Young LLP, where he worked as a manager in the Fraud Investigation and Dispute Services practice — one of the most respected forensic accounting teams in the profession. This grounding in large-scale financial investigation and dispute work, across both corporate and criminal contexts, forms the foundation of Inquesta Forensic.

Rob co-founded Inquesta in 2012, building the forensic accounting practice alongside the firm’s broader insolvency and business recovery services. As the forensic accounting work grew, in 2023 Rob established Inquesta Forensic as a dedicated, independent forensic accounting practice — while retaining the Inquesta name to reflect the continuity of his practice and client relationships.

Areas of Specialism

The Forensic accounting discipline perfectly balances financial analysis and legal expertise. The cases Rob regularly handles reflect this complexity. Over the course of 20 years of specialist practice, he has built deep expertise across six primary areas of forensic accounting work:

Proceeds of Crime Act (POCA) Confiscation Proceedings

POCA work is a cornerstone of Inquesta Forensic’s practice. Rob regularly challenges prosecution benefit figures and available amount assessments in the courts, consistently achieving significant reductions to the amounts defendants are required to pay.

Fraud Investigations and Criminal Defence

Rob has defended individuals facing mortgage fraud, tax evasion, money laundering, and Ponzi fraud allegations. He prepares CPR-compliant expert reports for criminal proceedings and has given evidence in court on a number of occasions.

Commercial and Contractual Disputes

Dispute instructions have included defending a $12 million commercial claim and quantifying losses from mis-sold Interest Rate Hedging Products. Rob produces expert reports for court and mediation covering breach of contract, warranty claims, and loss of profits.

Business valuation

Rob acts as single joint expert and party-appointed expert in shareholder disputes, unfair prejudice claims, management buy-outs, and matrimonial proceedings — producing reports compliant with procedural and court-defined standards.

Business Interruption Claims

Rob quantifies losses for claimants, loss adjustors, and insurers following interruption events including fire, flood, cyber attack, and supply chain failure. This establishes the pre-interruption baseline and allows for calculations of the full period of loss.

Matrimonial and Family Disputes

Where business assets form part of a financial remedy case, Rob provides valuations and forensic analysis compliant with the Family Procedure Rules, acting as both party-appointed expert and single joint expert.

Rob’s Case Experience

Acting for the defence in confiscation proceedings involving a convicted drug dealer, Rob reviewed thousands of emails to reconstruct the defendant’s accounts and calculate the true benefit from criminal activity. The prosecution had assessed both the benefit figure and available amount at over £5 million. Based on Rob’s evidence, the confiscation order was reduced to under £300,000.
Instructed to defend an individual charged with mortgage fraud on the basis of allegedly overstated income, Rob analysed the defendant’s earnings across a six-year period. His analysis demonstrated that the income had not been overstated. The prosecution dropped the case before it reached trial.
In a fraud and money laundering investigation, Rob was instructed to defend an individual accused of income tax evasion. The work involved reconstructing 12 years of profit and loss accounts to calculate the tax that would have been payable. Rob gave evidence in court.
As part of a complex Ponzi fraud case, Rob prepared the defence expert report and supporting schedules, then entered into discussions with the opposing forensic accountant to agree a schedule of agreed points before giving evidence in court.
Instructed to investigate a significant discrepancy in the accounts of a UK subsidiary of a FTSE-listed company, Rob used analytical review of high-volume journal postings to identify systematic manipulation of results by senior management sustained over five years.
In a commercial dispute, Rob was instructed to defend against a claim of approximately £5 million brought by the purchaser of a business, alleging breach of warranties and FSA regulation breaches. Rob’s analysis supported a counterclaim for breach of contract, resulting in the client receiving over £100,000 at mediation.
Instructed after HMRC seized cash from a client operating three large cash-based newsagents, Rob performed a cash tracing exercise to establish whether the funds could have originated from legitimate trade. HMRC returned the cash to the defendant.

Rob is experienced in giving expert witness evidence in court and has appeared in proceedings across a range of jurisdictions.

He prepares reports in compliance with CPR Part 35 and the Family Procedure Rules, and has acted as both party-appointed expert and single joint expert. He is a member of the Academy of Experts, which requires adherence to a formal code of practice for expert witnesses.
