Property insurance is meant to protect you if something goes wrong — fire, flood, structural damage, theft of fixtures. But the protection an insurance policy actually provides depends entirely on one number most owners never question closely: the property’s insured value.
If that value is based on an outdated or inaccurate valuation, the coverage itself may not be enough when you actually need to make a claim.
Underinsurance: The Risk Nobody Notices Until It’s Too Late
Underinsurance happens when a property is insured for less than its actual current value — often because the valuation used to set the policy was done years earlier, before renovations, market shifts, or rebuilding cost increases changed what the property is genuinely worth.
The problem with underinsurance is that it stays completely invisible until a claim is filed — at which point the payout may fall well short of what’s actually needed to repair or rebuild. Some insurers also apply what’s known as an average clause, reducing the payout proportionally if the property was insured below its true value, even for a partial claim.
Overinsurance Wastes Money Quietly
The opposite problem — insuring a property for more than it’s actually worth — doesn’t create a coverage gap, but it does mean paying premiums calculated on an inflated value. Over years, this can add up to a meaningful, avoidable cost.
Why the Original Purchase Valuation Isn’t Enough
Many property owners insure based on the valuation done at the time of purchase and never revisit it. But construction costs, material prices, and market values shift over time — sometimes significantly within just a few years. A valuation from five or ten years ago is unlikely to reflect what it would actually cost to rebuild or replace the property today.
Getting the Insured Value Right
The insured value should reflect current rebuilding or replacement cost, not simply the market sale price — these two figures are related but not identical. A professional valuation specifically for insurance purposes accounts for construction costs, materials, and labour at today’s rates, which is what actually determines what it would cost to rebuild if the worst happened.
Revisiting this valuation periodically — particularly after any renovation, or every few years even without changes — helps ensure the policy reflects reality rather than a snapshot from whenever the property was first insured.
