Fire, Flood & Property Damage BI Expert Witness
Fire and flood remain the most common triggers for UK business interruption claims. In litigation, the dispute often centres on the length of the indemnity period, the application of the rate of gross profit to shortfalls in turnover, and whether additional expenditure qualifies as increase in cost of working (ICW) during reinstatement.
A business interruption expert witness analyses the repair period alongside the time required for the business to return to the financial position it would have occupied absent the loss - subject always to the maximum indemnity period (MIP) in the policy. Experts integrate property damage timelines with trading evidence, seasonality, and post-loss recovery patterns.
Where insurers dispute quantum, the expert’s role is to establish a defensible standard turnover baseline, quantify saved expenses and insured standing charges correctly, and present transparent workings suitable for CPR Part 35 scrutiny and joint expert discussions.
Frequently Asked Questions
How is the indemnity period calculated after a fire?
The indemnity period runs from the date of damage until the business returns to the financial position it would have been in absent the loss, subject to the Maximum Indemnity Period. This covers physical reinstatement plus the time to rebuild customer base and revenue - not just the repair timeline.
What financial records are needed for a fire BI claim?
Pre-loss management accounts, audited accounts for 3 prior years, monthly profit & loss, VAT returns, payroll records, and evidence of post-loss trading.
