Business interruption cover: replacing income when you cannot trade

A fire that damages a shop's premises is, in insurance terms, two separate losses. The first is the physical damage — stock destroyed, fittings burnt, the unit unusable — and a commercial property policy is built to pay for that. The second is quieter but often larger over time: the revenue the business does not earn while it cannot trade from that unit, and the fixed costs — rent, salaries, loan repayments — that keep running regardless. Business interruption (BI) cover is the policy that responds to the second loss, and a business without it can survive the repair bill and still fail from the months of lost income in between.

Why property cover alone is not enough

A standard commercial property or fire policy indemnifies the cost of repairing or replacing damaged buildings, fittings and stock, up to the sums insured chosen. It does not, on its own, pay a business's ongoing rent, staff wages, loan servicing or the gross profit the business would otherwise have earned while the premises are being rebuilt or a licence is being reinstated. Those costs continue whether or not the business is trading, and BI cover exists specifically to bridge that period.

In Singapore, commercial insurance covering property, business interruption and related SME risks is sold by general insurers licensed and supervised by the Monetary Authority of Singapore under the Insurance Act, and offered by insurers such as MSIG alongside their property, liability and other commercial lines. BI is typically sold as an extension attached to a property policy, triggered by the same insured events — commonly fire, and depending on the policy, other perils the property cover itself responds to — rather than as a fully standalone product.

What the cover is actually built to calculate

BI policies are usually structured around one of two approaches, and the difference changes what actually gets paid:

• Gross profit basis. The insurer pays the gross profit the business would have earned during the interruption, calculated from historical trading figures, plus increased costs incurred to keep the business running or to minimise the loss.
• Fixed costs / additional expenditure basis. A narrower version that reimburses defined standing costs and reasonable additional expenses during the interruption, without calculating a full gross profit loss.

Whichever basis applies, three details decide whether the payout is actually enough when a claim happens:

1. The indemnity period — the maximum length of time the policy will pay for. If reinstating the premises, replacing specialist equipment or waiting for licences realistically takes longer than the chosen indemnity period, the shortfall is the business's own loss.
2. The sum insured, based on projected trading figures. This should reflect where the business is heading, not where it was at the last renewal — a growing business under-insured on last year's numbers can find its payout capped well below its actual loss.
3. Which perils actually trigger the extension. BI attached to a fire policy typically responds to the same named perils; it does not automatically extend to every possible cause of a trading interruption, such as a supplier's failure or a wider utility outage, unless specifically added.

Who tends to need this most

Any business with significant fixed overheads relative to its cash reserves — a lease, staff, equipment financing — is exposed to this gap regardless of size. It is particularly relevant for businesses operating from a single premises with no easy alternative trading location, and for those in sectors where reinstatement (specialist fit-out, licensing, equipment lead times) tends to take longer than a general contractor's repair estimate would suggest.

What to check before renewing or buying

• Does the BI extension match the indemnity period a realistic worst-case reinstatement would actually take?
• Is the sum insured based on current or projected trading figures, reviewed at each renewal?
• Which perils trigger the BI extension, and do they match the risks the business is actually exposed to?
• Does the policy cover increased cost of working — the extra expense of operating from a temporary location — separately from the core loss-of-profit calculation?

Talk to an advisor

Sizing business interruption cover correctly depends on figures specific to each business — its margins, fixed costs and realistic reinstatement time — that a generic policy limit will not reflect accurately. A licensed advisor can work through those figures with you before your next renewal. Find one through our advisor matching, or ask our assistant about a specific commercial policy's BI terms.
