Business interruption (BI) insurance replaces the profit your business loses while it cannot trade normally after insured physical damage — a fire, a flood, a burst pipe — and pays the extra costs of keeping the business running in the meantime. It sits on top of your property policy: the property cover pays to repair the premises and replace equipment, while BI covers the gross profit that walked out the door during the months of closure, plus continuing costs like rent and salaries. For many SMEs, that trading loss exceeds the physical damage itself.
How BI sits on top of property cover
Picture a fire in your unit. Two distinct losses follow:
- The physical loss — damaged fit-out, equipment and stock. Your commercial property policy pays to repair and replace these.
- The trading loss — every week the doors are shut, revenue stops but rent, salaries, loan payments and supplier commitments continue. Customers drift to competitors. This is BI's territory.
BI typically covers the shortfall in gross profit against what you would have earned, and it usually can't be bought standalone — it attaches to the property policy, responds to the same insured perils, and settles alongside the property claim. Some policies extend to scenarios like denial of access (your street closed by a neighbouring fire) or utility failure; those extensions vary widely, so check what's actually included.
Gross profit and increased cost of working
Two concepts do most of the work in a BI policy:
- Gross profit (in the insurance sense) — broadly, your revenue minus purely variable costs like ingredients or stock that you don't incur while closed. It intentionally includes fixed costs and payroll, because those continue whether or not you trade. Declare it accurately: like property cover, BI applies underinsurance principles, and a understated gross profit figure scales down the claim.
- Increased cost of working (ICW) — the extra spending that reduces the overall loss: temporary premises, overtime, expedited equipment shipping, extra marketing to win customers back. Policies typically pay ICW where it economically reduces the claim — spending S$10,000 on a temporary kitchen to preserve S$40,000 of profit is exactly what this section is for.
Some smaller packages offer a simpler alternative — a fixed daily allowance for each day closed — which is easier to claim but rarely matches a real profit loss.
The indemnity period: the setting most SMEs get wrong
The maximum indemnity period is how long the policy will keep paying from the date of damage — commonly 12 months, extendable to 18, 24 or 36. It needs to cover not just repairs but full recovery:
- Reinstatement is rarely quick: damage assessment, claim agreement, landlord and authority approvals, contractor lead times, fit-out, licensing re-inspections — then reopening.
- Revenue doesn't snap back on reopening day; rebuilding a customer base takes months more.
Twelve months sounds generous until you map a real timeline; many businesses find 18–24 months is the honest number, especially where landlords, MCSTs or regulators sit in the approval chain. The indemnity period is a choice you make at purchase, not at claim time — choose it by walking through your own worst-case rebuild, step by step.
A worked example: fire in a café
An illustrative (not predictive) scenario. A café's kitchen fire causes S$150,000 of damage to fit-out and equipment. The unit takes seven months to reopen: two months of claim assessment and approvals, four months of reinstatement works, one month of re-licensing and rehiring. Trade takes another three months to return to normal.
| Loss | Which policy responds | Illustrative amount |
|---|---|---|
| Fit-out, kitchen equipment, stock | Property (fire/all-risks) | S$150,000 |
| Lost gross profit over ~10 months of closure and recovery | Business interruption | Often comparable to or exceeding the property loss |
| Continuing rent and payroll for retained staff | Business interruption (within gross profit) | Continues monthly throughout |
| Temporary stall to keep the brand alive; reopening marketing | Business interruption (increased cost of working) | Paid where it reduces the overall loss |
With property cover only, this café gets a rebuilt room and ten months of unfunded outgoings. With BI and a sufficient indemnity period, it gets both the room and the runway. Note the indemnity period lesson hiding in the numbers: a 12-month period covers this timeline; a 6-month period would have stopped paying mid-reinstatement.
Frequently asked questions
What is business interruption insurance?
Business interruption insurance replaces the profit your business loses while it can't trade normally after insured physical damage such as a fire or flood, and pays the increased costs of keeping the business going in the meantime. It works alongside your property policy: property cover repairs the premises; BI covers the trading loss during repairs and recovery.
Can I buy business interruption insurance without property insurance?
Generally no — BI attaches to a property policy and is triggered by physical damage insured under it. If the peril isn't covered on the property side, the BI section typically won't respond either, which is why the two covers should be designed together with matching perils and values.
What does gross profit mean in business interruption insurance?
In BI policies, gross profit broadly means revenue minus purely variable costs (like stock or ingredients you don't buy while closed) — deliberately including fixed costs and payroll, because those continue during closure. It differs from the accounting definition, and understating it triggers underinsurance scaling on claims, so calculate it with your accountant or a licensed professional.
How long an indemnity period do I need?
Long enough to cover full recovery, not just repairs — claim assessment, approvals, reinstatement, re-licensing, and the months it takes revenue to return to normal after reopening. Twelve months is the common default, but businesses with landlord, MCST or regulatory approval chains often find 18–24 months is the realistic figure.
Does business interruption insurance cover pandemic closures?
Standard BI policies generally do not — they require physical damage to trigger, and closure by disease or government order without property damage typically falls outside cover, with infectious-disease extensions restricted across the market in recent years. If this exposure matters to you, ask the question explicitly before buying rather than assuming.
