Machinery breakdown insurance in Singapore for factories
What a fire policy leaves out
A commercial fire or property all risks policy insures machinery against external perils: fire, lightning, explosion, flood, impact, theft. It excludes damage that starts inside the machine. A compressor that seizes, a transformer that shorts, a CNC spindle that fails under load. Each is a breakdown, and the property policy does not respond.
Machinery breakdown insurance, also called boiler and machinery insurance, fills that exclusion. One insurer's published wording covers physical loss or damage to machinery while in operation, unless excluded, with options to add business interruption and goods in cold storage.
| Cause of loss | Fire or property all risks | Machinery breakdown | Machinery all risks |
|---|---|---|---|
| Fire, lightning, explosion | Covered | Excluded | Covered |
| Flood, water damage | Covered if selected | Excluded | Covered |
| Theft | Covered if selected | Excluded | Covered |
| Electrical short circuit inside the machine | Excluded | Covered | Covered |
| Mechanical failure, seizure | Excluded | Covered | Covered |
| Operator error, dropping during handling | Usually excluded | Covered | Covered |
| Wear and tear, corrosion | Excluded | Excluded | Excluded |
Machinery all risks combines both sets of perils in one policy. One bank-distributed product describes it as covering fire, flood, theft and accidental damage, filling gaps left by maintenance contracts. The choice depends on what the property policy already covers and whether the plant moves.
Which plant is insured
Underwriters write machinery breakdown for a schedule of items, not a blanket sum. Common schedules in Singapore include:
- Production lines in food processing, printing, precision engineering and plastics.
- Boilers, pressure vessels, compressors and chillers.
- Transformers, switchgear and generators.
- Lifts, escalators and building services plant in commercial buildings.
- Refrigeration plant for cold rooms and central kitchens.
- Medical and laboratory equipment.
Each item is listed with its make, model, year and replacement value. Items left off the schedule are not insured. The broker reconciles the schedule to the fixed asset register at each renewal and adds new plant mid-term by endorsement.
Electrical breakdown cover for switchboards and transformers is often the most valuable item on the list. A failed transformer can stop a whole site, and the lead time for a replacement can run to months.
Business interruption after a breakdown
Property damage is the smaller loss. A S$200,000 compressor that takes 10 weeks to replace can stop S$2 million of output. Machinery breakdown business interruption pays the gross profit lost, or the increased cost of working, during the indemnity period.
The indemnity period is the number of months the policy will pay for. It must cover the longest realistic replacement lead time plus commissioning. For imported plant that is 6 to 12 months, not 3. The broker sets it from the supplier's quoted lead times, not from a default. See business interruption indemnity period for how the period is set.
Cold storage deterioration is a related extension. It pays for stock spoiled when refrigeration plant breaks down or power fails. Food manufacturers, central kitchens and pharmaceutical warehouses carry it. The sum insured is the peak stock value in the cold room.
Property insurance claims in Singapore rose 60.5% in 2025 on premiums of S$864.1 million. The industry's own statement links the rise to fire incidents and several large losses. Business interruption is where a mid-sized loss becomes a large one.
What is excluded
Breakdown wordings share a core list of exclusions:
- Wear and tear, erosion, corrosion, scale and gradual deterioration.
- Faults existing at inception that the insured knew about.
- Damage the manufacturer or supplier is liable for under warranty.
- Consumable parts: belts, filters, tooling, bulbs, refrigerant.
- Wilful overloading or operating outside the maker's specification.
- Fire, explosion and theft, which belong to the property policy.
Exclusions are why a maintenance contract does not replace insurance, and insurance does not replace maintenance. A maintenance contract covers scheduled service and parts that wear. Insurance covers the sudden failure that maintenance did not prevent. An insurer may decline a claim where service records show a missed overhaul, so the records are part of the risk.
Non-residential premises fires rose 13.5% to 471 in 2025, and electrical faults caused 43.5% of them. An electrical fault that starts a fire is a property claim. The same fault that destroys only the switchboard is a breakdown claim. The 2 policies need to meet without a gap, and the broker aligns the excess and the definitions so that neither insurer can point at the other.
Setting the sum insured for second-hand machines
Breakdown cover is written on a reinstatement basis. The sum insured is the cost of replacing the item with a new one of the same capacity, including freight, duties and installation. It is not the book value and not the second-hand price paid.
Worked example. A factory bought a used injection moulding machine for S$120,000. A new equivalent costs S$350,000 delivered and installed. If the item is insured for S$120,000 and suffers a S$60,000 repair, the insurer applies average: S$60,000 × (120,000 ÷ 350,000) = S$20,571. The owner bears S$39,429 plus the excess. Insured at S$350,000, the full S$60,000 less excess is paid. The example is arithmetic, not a quotation.
Older machines may be written on an indemnity basis instead, paying market value less depreciation. That lowers the premium and the claim in equal measure. The owner should choose knowingly.
What moves the premium
The broker's submission sets the rate through 6 inputs:
- Type and age of plant, with rotating machinery and high-pressure plant rated higher.
- Total sum insured on the schedule and the largest single item.
- Maintenance regime, with service contracts and records as evidence.
- Operating hours: 1 shift or 3.
- Business interruption sum insured and indemnity period, if added.
- Claims history for 5 years.
Manufacturing recorded 124 workplace fatal and major injuries in 2025, 20% of the national total. Plant that fails can injure the operator as well as stop production, so work injury compensation and breakdown cover are reviewed together. A factory with documented service records and a current asset schedule gets a cleaner quotation than one that presents a lump sum. Product details are at machinery breakdown insurance.
Frequently asked questions
Does fire insurance already cover machinery breakdown?
No. Fire and property all risks policies exclude damage that starts inside the machine, such as electrical short circuit or mechanical failure. They pay only when an insured external peril, such as fire or flood, damages the plant. Breakdown needs its own policy or a machinery all risks policy.
Is wear and tear excluded?
Yes, on every wording. Gradual deterioration, corrosion and consumable parts are the owner's maintenance cost. The policy pays for the sudden failure that follows, but not for the worn part that caused it unless the wording says otherwise.
Can I insure lost production after a breakdown?
Yes, by adding machinery breakdown business interruption. It pays lost gross profit or increased cost of working for the indemnity period chosen. The period should match the longest replacement lead time, which for imported plant can be 6 to 12 months.
How is the sum insured set for second-hand machines?
At the cost of a new replacement of the same capacity, delivered and installed, if the policy is on a reinstatement basis. Insuring at the purchase price of a used machine triggers average, which cuts every claim in proportion. An indemnity basis at depreciated value is the alternative, with a lower premium and lower claim.
