IAR vs Fire Insurance Malaysia: Which One Does Your Factory Actually Need?

Does your factory actually need IAR, or is fire insurance enough? Most buyers ask the question the wrong way around. They compare the two products line by line, find IAR "better" on paper, and buy it without asking whether the extra coverage costs more than the risk it protects against.

This article is a decision framework, not a comparison chart. By the end, you should know which cover fits your factory today, and what would need to change for the answer to flip.

We skip the product glossary (we have a comparison guide for that) and focus on the actual decision: sum insured thresholds, occupancy mix, claim likelihood, and the specific scenarios that push a factory one way or the other.

The Quick Answer (For Readers in a Hurry)

If your factory is small, occupies a single building, runs a low-hazard process, and has straightforward property, fire insurance is usually enough. If your factory is mid-to-large, has complex occupancy, depends on expensive machinery or stock, or sits in a flood or multi-peril zone, IAR is usually the right answer.

But the quick answer is wrong in specific cases, and those cases are where factories lose money. Read on.

What "Fire" and "IAR" Actually Differ On

At the highest level, fire insurance is a named-perils policy and IAR is an all-risks policy. Fire pays when a listed peril (fire, lightning, explosion, and optionally flood, storm, impact, riot) damages insured property. IAR pays when "any accidental physical damage" happens to insured property, subject to standard exclusions. The burden of proof is inverted. Under fire, the insured proves the peril. Under IAR, the insurer proves the exclusion.

That difference matters at claim time. It matters less at renewal time, because both are property policies and both are priced on similar rating factors.

The Five Tests That Decide

Rather than weighing feature lists, run these five tests against your own factory. If three or more point toward IAR, that is likely the right answer. If three or more point toward fire, fire insurance is likely enough.

Test 1: What Is Your Total Sum Insured?

This is the single biggest practical driver. Insurers and the market itself treat fire insurance as the natural home for small to mid-sized risks, and IAR as the natural home for larger ones.

Total Sum Insured RangeMarket DefaultWhen to Push BackBelow RM10 millionFire insuranceHigh-value stock, complex machinery, flood-proneRM10 to RM30 millionEither works; compare on price and scopeDepends on occupancy and loss exposureAbove RM30 millionIAROnly if occupancy is simple and claims history is clean

Test 2: How Complex Is Your Occupancy?

Single-process factory with one clear occupancy class? Fire insurance handles this cleanly. Mixed process (production plus warehouse plus office plus R&D), multiple storage classes, or process changes over time? IAR handles this more cleanly because the coverage scope follows the physical assets rather than a peril list.

Test 3: What Is Your Biggest Single Loss Exposure?

Run this thought experiment: imagine the worst-case claim your factory could suffer. Is it a fire that destroys the building and stock? Fire insurance can handle this. Is it an unforeseen event that a peril list might not capture (a process-related spillage, a rare mechanical failure, a contamination event, an impact from an adjacent structure)? IAR is designed for this ambiguity.

Test 4: How Sophisticated Is Your Risk Management?

Counter-intuitive but true: factories with better risk management usually benefit more from IAR, not fire. Why? Because IAR rewards documented controls. A factory with predictive maintenance, thermography, hot work permits, and sprinkler AMCs presents the kind of risk profile that insurers will cover comprehensively at a reasonable rate. A factory without those controls may find IAR expensive, because the insurer is pricing unknowns.

Test 5: How Much Claim-Time Ambiguity Can You Tolerate?

Fire insurance disputes often turn on whether the peril was covered. IAR disputes turn on whether the exclusion applies. If your finance team and your ops team cannot afford a 6-month claim investigation while production is halted, IAR generally clears faster because the argument is narrower.

Where Factory Owners Get This Wrong

Three common errors we see at policy audits:

Error 1: Assuming IAR is Always More Expensive

Sometimes it is. Often it is not. An IAR programme priced against a well-documented risk can come in below a fire insurance policy with multiple extensions (flood, storm, riot, water damage, etc.), because the IAR base rate absorbs all those perils without individual loadings. Always compare on like-for-like scope, not headline premium.

Error 2: Buying Fire When the Process Has Outgrown It

The factory starts with a simple process, buys a standard fire policy, and keeps renewing. Over 5 years, the process expands, the stock value triples, a new storage area is added, and nobody re-evaluates the insurance structure. The fire policy is now trying to cover risks it was never designed for, and the next claim exposes the mismatch.

Error 3: Buying IAR Because Someone Said To

A small-to-mid factory with a clean occupancy and a tight asset register may be better served by a well-structured fire policy with targeted extensions. IAR sometimes gets recommended because it is "safer," not because it is the best fit. Ask why. If the answer is vague, push back.

Does Switching at Renewal Cost More?

In principle, switching from fire to IAR (or vice versa) at renewal costs nothing more than the normal quote process. In practice, a mid-term switch requires additional underwriting work and may attract loading. Do it at renewal if possible.

The switch is also a good trigger to re-evaluate sum insured. Most factories that switch from fire to IAR discover their fire policy was under-insured, because the reinstatement basis drift was never corrected. Catching this before a claim is worth the exercise even if you decide not to switch.

What About Business Interruption?

Both fire and IAR typically pair with a Business Interruption (BI) section. The BI cover responds when a property damage claim halts production. BI sum insured is usually the larger of the two covers for mid-sized manufacturers, because revenue loss over 6 to 12 months often exceeds the property damage value.

Whichever property cover you choose, the BI section is where most factories are under-insured. See our business interruption insurance guide.

FAQ

Is IAR always better than fire insurance?

No. IAR is wider, but width is not always value. Small factories with simple risks often get better value from a properly-structured fire policy than from a generic IAR programme. The question is fit, not feature count.

Can I have both fire and IAR on the same property?

You don't need to. An IAR policy already covers fire perils, and running both creates overlap that complicates claims. If you are moving from fire to IAR, the old fire policy should be cancelled or non-renewed.

Does IAR cover flood and storm automatically?

Most IAR policies in Malaysia include flood and storm in the base cover, subject to exclusion zones and sub-limits. Fire insurance includes flood and storm only if the respective extension is purchased. This is one of the most common reasons buyers switch to IAR in flood-exposed industrial parks.

Does IAR cover machinery breakdown?

IAR covers external physical damage to machinery but typically excludes internal mechanical or electrical breakdown. For that, you still need a separate MB/MLOP cover. See the MB insurance page for scope.

Is IAR more expensive for smaller factories?

Often yes, because insurers have minimum premiums for IAR programmes that make the cost per RM1 million of sum insured higher for small risks. This is the main practical reason why fire insurance dominates the under-RM10-million market.

Does IAR cover theft?

Most IAR policies include theft accompanied by forcible entry and violent means (burglary), subject to sub-limits. Simple shrinkage or employee dishonesty is usually excluded or requires a separate fidelity cover.

If I have a multi-site business, should I go IAR?

Usually yes. IAR is easier to administer across multiple locations with one declaration, and the premium economics typically favour IAR once you pass 2 or 3 sites. Multi-site fire policies also work, but reconciling extensions across sites becomes admin-heavy.

Foundation Conclusion

The fire versus IAR decision is not won by feature comparison. It is won by honest assessment of your factory's sum insured, occupancy complexity, loss exposure, and risk management maturity. The right product is the one that leaves fewer unanswered questions at claim time for a reasonable annual cost.
