Fire insurance and Building insurance are frequently used interchangeably to cover the physical structure of a property (walls, floors, roof) against perils like fire, lightning, and explosions. While fire insurance is sometimes more limited in scope, modern “fire insurance” often acts as building insurance, though neither typically covers internal home contents. In this article we will refer to Fire insurance, but the same is applicable to a Building insurance.
Your mortgage lender requires fire insurance. You purchase a policy. You assume you’re protected.
This assumption costs property owners thousands—sometimes hundreds of thousands—when disaster strikes.
I’ve spent years helping property owners understand fire insurance, and the gap between what people think they have and what they actually need remains one of the most dangerous blind spots in property ownership. An estimated 70% of properties are underinsured, whilst others overpay for coverage they don’t need.
The problem isn’t that people don’t care about protection. The problem is that they’re protecting the wrong thing.
The Three Numbers That Create Confusion
When you think about your property’s value, three fundamentally different numbers exist.
Market value is what you paid for the property. It includes the building, the land, location premium, supply and demand factors, and the developer’s profit margin if you bought new construction.
Rebuilding cost is the actual cost of materials and labour to reconstruct that specific structure. When you rebuild, you’re not paying for location or market conditions. You’re paying construction costs.
Mortgage amount is what you borrowed from the bank—typically a percentage of the market value after your deposit.
Your bank only cares about protecting the money they lent you. That’s why they require fire insurance matching your mortgage amount.
But here’s what catches people off guard: your mortgage amount may be significantly more or significantly less than your actual rebuilding cost.
Why Market Value Creates Dangerous Assumptions
The biggest misconception I encounter is property owners insuring for market value. This seems logical—you paid HKD 5,000,000 for your property, so you insure it for HKD 5,000,000.
In most cases, this means you’re overinsured.
Mant property owners mistakenly think the amount of fire insurance they need is based on the market value of their home. Market value includes the land, which can represent a substantial portion of your property’s worth. When you rebuild after total loss, the land is already there. You’re only replacing the structure.
Rebuilding cost typically runs lower than market value because it strips away all the market premium—the desirable neighbourhood, the school catchment area, the trendy postcode.
The reverse creates the more dangerous scenario. Some property owners assume insuring for their mortgage amount provides adequate protection. If your mortgage represents 80% of market value and your rebuilding cost sits at 60% of market value, you’re probably fine. But if your mortgage sits well below your actual rebuilding cost, you’re financially exposed.
When Rebuilding Costs Exceed Market Value
Whilst uncommon, situations exist where rebuilding actually costs more than market value.
This happens in less attractive areas where the gap between construction costs and market value narrows. Imagine a scenario where labour and material costs spike due to high demand, but market values in that particular neighbourhood stagnate because people are moving away.
You’re left holding a property that costs more to rebuild than buyers will pay.
Luxury or historic properties often require very careful restoration using specialised materials and craftsmanship, driving reinstatement cost beyond the market value.
The Rebuild Cost Calculation Challenge
Determining accurate rebuilding cost proves remarkably difficult.
You can purchase this information from specialist companies or use online calculators. But any calculation remains a best estimate.
Your calculation becomes outdated quickly.
Do your best to estimate rebuilding cost based on available data, your home’s size, and your property’s grade—low, medium, or luxury. A basic property using simple materials won’t cost the same to rebuild as a luxury home featuring imported Italian marble. This estimate becomes the foundation for your fire insurance coverage.
The Solution That Removes Guesswork
An alternative approach eliminates the estimation challenge entirely.
Some insurers offer fire insurance that charges a fixed premium based on your property’s size and age but guarantees to pay the actual rebuilding cost or your outstanding mortgage amount at the time of loss.
This removes the burden of estimating rebuilding costs and adjusting your sum insured annually for inflation or mortgage reduction. Banks typically charge a service fee every time you change your fire insurance sum insured, making annual adjustments prohibitively expensive.
For 95% of cases, this guaranteed replacement approach proves worthwhile.
The limitations? Not many insurers offer this structure. If you have a very small mortgage or exceptionally low rebuilding costs, you may overpay in premium. Properties older than 50 years typically don’t qualify—presumably due to higher risk and uncertainty around older construction methods and materials.
Hidden Factors That Inflate Rebuilding Costs
Even accurate rebuilding cost calculations miss critical factors that emerge during actual reconstruction.
Current building codes create the largest and most frequent source of underinsurance. When you rebuild, you must comply with modern standards—updated electrical systems, environmental compliance, sprinkler systems, improved insulation—even if your original structure was built decades ago.
These changes may significantly increase rebuilding costs beyond what a standard calculation tells you.
Construction input prices can rise sharply due to supply and demand, as well as global factors such as trade wars or supply chain disruptions. This volatility means even recent calculations become outdated rapidly.
The Scale of the Problem
The human cost is equally severe. Many homeowners are unaware of gaps in their coverage, with most choosing policies based on premium costs rather than total coverage.
Policy Exclusions That Shock Homeowners
Exclusions like war or nuclear fallout exist in fire insurance policies. You’re unlikely to face these scenarios. But if you do, you’re facing total loss with no coverage.
More realistic concerns centre on water damage. Standard homeowners insurance typically excludes many types of water damage—flood, surface water, and water backing up through sewers or drains.
The Tai Po case last year demonstrated complexity at scale—several towers burnt down simultaneously. The claims process stretched on as insurers assessed all claims and determined liability. When third parties bear responsibility, insurers pursue those entities to recover losses, extending the timeline before you receive settlement.
What Property Owners Get Wrong During Claims
You should examine excess terms carefully. They vary dramatically between insurers, particularly for water damage claims.
For the same property, I’ve seen policies ranging from nil excess to HKD 10,000 or 10% of the claim amount, whichever is higher.
That difference becomes substantial on a HKD 500,000 water damage claim. One policy pays the full amount. Another requires you to cover HKD 50,000 yourself.
Most property owners don’t compare excess terms when purchasing fire insurance coverage. They focus on premium costs and coverage limits, missing this critical detail that determines your out-of-pocket expense when you actually need to claim.
The Responsibility Gap
Here’s the uncomfortable truth: it’s your responsibility, not your insurer’s, to ensure you have adequate fire insurance coverage.
Far too many homeowners have no idea what rebuilding their home would actually cost. Many homeowners simply buy the coverage amount their bank suggests to cover their mortgage.
That suggestion often isn’t enough.
Over two-thirds of homes are currently underinsured. There is a growing disconnect between property values and actual reconstruction costs.
Building a Proper Protection Strategy
Start by obtaining a professional rebuild cost assessment. Specialist companies provide detailed evaluations based on your property’s specific characteristics.
Review your fire insurance policy annually. Construction costs, building codes, and your property’s features change. Your coverage needs to keep pace.
Consider guaranteed replacement cost coverage if your property qualifies. This provides whatever is needed to replace your home in its original condition.
Document your property thoroughly. Photograph every room, major systems, finishes, and custom features. Store this documentation off-site or in cloud storage. When you need to claim, detailed records support accurate settlement.
Understand your excess structure across different claim types. Water damage, storm damage, and fire may carry different excess amounts.
Don’t assume your mortgage-required fire insurance coverage protects you adequately. It protects your lender. Your job is protecting yourself.
Why This Matters Now
Fire insurance isn’t just about satisfying your mortgage lender. It’s about protecting your most significant asset from devastating financial loss.
The gap between what people think they have and what they actually need continues to widen. Construction costs rise faster than property values in many markets abroad—this may become true in Hong Kong as well. Building codes become more stringent. Climate-related risks increase.
You can either address these realities proactively or discover them when you’re standing in front of your damaged property, realising your coverage falls HKD 1,000,000 short of what you need to rebuild.
