01 / Overview

What Is Business Interruption Cover?

Business interruption cover is one of the most critical sections of an ISR policy. While property damage insurance pays to repair or replace your physical assets, it does not compensate you for the income lost while your business is unable to trade. That is where business interruption cover steps in.

This section indemnifies you for the reduction in gross profit and the increased costs of working that result from an interruption to your business operations caused by an insured event - such as a fire destroying your warehouse, a flood damaging your shopfront or a storm disabling your production line.

For many businesses, the financial impact of lost revenue and ongoing fixed costs such as wages, rent, loan repayments and utilities far exceeds the cost of repairing the physical damage. Without business interruption cover, even a well-insured business could face insolvency during a prolonged shutdown.

02 / Inclusions

What Is Covered?

  • Loss of gross profit resulting from a reduction in turnover during the indemnity period
  • Ongoing fixed expenses such as wages, salaries, rent, rates and loan repayments
  • Increased costs of working to minimise the interruption (e.g. temporary premises, equipment hire)
  • Additional increase in cost of working to maintain turnover
  • Loss of revenue from denial of access to your premises due to damage in the vicinity
  • Loss following damage at suppliers' or customers' premises (when extension is purchased)
  • Loss resulting from failure of public utilities such as electricity, gas or water supply
  • Auditors' and accountants' fees incurred in preparing your claim
03 / Exclusions

Common Exclusions

Business interruption cover is subject to the same event-based exclusions as the property damage section - it only responds when the underlying cause of the interruption is an insured event. Additional exclusions and limitations include:

  • Losses arising from events that are excluded under the property damage section
  • Interruption not caused by physical damage to insured property (unless a specific extension applies)
  • Fines, penalties and contractual liabilities arising from late delivery or non-performance
  • Losses beyond the declared indemnity period
  • Loss of market share or goodwill that extends beyond the indemnity period
  • Deliberate under-declaration of turnover or gross profit (underinsurance provisions may apply)

Accurate declaration of your gross profit, turnover and indemnity period is essential. Underinsurance in this section can result in a significantly reduced claim payout through the application of average (proportional reduction).

Business Interruption FAQs

The indemnity period is the maximum length of time the insurer will pay business interruption losses after an insured event. It begins from the date of the loss and should be long enough to cover the time needed to fully restore your business operations. Most policies offer 12, 18, 24 or 36-month indemnity periods. Businesses with complex operations, specialised equipment or long rebuild timeframes should consider a longer indemnity period.
Under an ISR policy, gross profit is generally defined as revenue less variable costs (also known as uninsured working expenses). This figure represents the amount needed to cover your fixed costs and net profit. It is calculated differently from the accounting definition of gross profit, so it is important to work with your broker and accountant to ensure the declared sum insured accurately reflects your exposure.
Standard ISR business interruption cover responds when your own premises suffer physical damage from an insured event. However, extensions for suppliers and customers premises can be added, providing cover when damage to a key supplier or customer's property impacts your revenue. These extensions are usually subject to sub-limits.
Increased costs of working are additional expenses you incur to minimise or avoid a reduction in turnover after an insured event. Examples include renting temporary premises, hiring replacement equipment, paying overtime or express freight charges. These costs are covered under the business interruption section, provided they help reduce the overall loss.
