Business Interruption

Loss that stands up to the insurer's expert.

Business interruption claims turn on the counterfactual - what the business would have earned had the interruption not occurred. We reconstruct pre-interruption performance from primary records and model the loss on a basis that is transparent and defensible.

Every quantum report is prepared as an independent expert under CPR Part 35, written to withstand challenge from the insurer's own appointed accountant.

What We Cover

Quantum that survives the other side's scrutiny.

A business interruption figure is only as strong as the assumptions behind it. We set out the basis of calculation clearly so the loss can be tested, defended and relied on - whether the claim settles or proceeds to a contested hearing.

Common Questions

Business interruption questions answered.

If your question is not covered below, contact us directly and we will respond the same working day.

  • The loss is the difference between the financial position the business actually achieved and the position it would have achieved had the interruption not occurred. We reconstruct the pre-interruption baseline from primary records, model the counterfactual taking account of trends and market factors, and set the loss against the relevant indemnity period and policy terms.
  • We accept instructions from policyholders, insurers and their legal advisers. As an independent expert our primary duty is to the court, and our analysis is prepared to the same standard whoever instructs us.
  • Our reports are written to be tested. We state the basis of calculation, the assumptions relied on and the records used, so the figure can be defended in correspondence, in a joint statement with the opposing expert, and in oral evidence if the matter proceeds to a hearing.
  • Timelines depend on the complexity of the business and the completeness of the records. We agree a realistic timetable at the outset and work to any court or policy deadlines. Urgent instructions can be accommodated where capacity allows.
  • Yes. All quantum reports are prepared to comply with CPR Part 35 and the accompanying Practice Direction, including the required declaration and statement of truth, with the expert's duty to the court overriding any duty to the instructing party.
