Many people assume that having property insurance means their home is fully protected.
But insurance only works properly if the amount you insure your property for reflects its true value.
If your home is insured for less than it would actually cost to rebuild, you may receive a lower payout than expected when making a claim.
This is known as underinsurance, and it’s one of the most common mistakes people make when arranging property insurance.
The good news is that it’s also one of the easiest problems to prevent once you understand how it works.
The Short Answer
Underinsurance happens when your property is insured for less than the amount required to rebuild or replace it.
If this happens, your insurer may reduce your claim payment proportionally based on the level of underinsurance.
In simple terms:
Being insured does not always mean you’ll receive the full amount of your loss.
The insured amount needs to accurately reflect the real cost of rebuilding your property.
A Question Worth Asking
If repairing damage to your home cost CZK 1,000,000, would you expect your insurance to cover the full amount?
Most people would.
However, if your property was insured for significantly less than its true rebuilding value, the claim payment may be reduced because the property was not adequately insured.
That’s why choosing the right insured amount is just as important as having property insurance itself.
How Does Underinsurance Work?
The easiest way to understand underinsurance is through an example.
Imagine your home would cost CZK 10,000,000 to rebuild.
However, your insurance policy covers it for only CZK 5,000,000.
This means your property is insured for only 50% of its true rebuilding value.
Now imagine a fire causes CZK 1,000,000 worth of damage.
Because your property was only insured for half of its actual rebuilding cost, the insurer may apply the same proportion to the claim.
Instead of receiving the full CZK 1,000,000, you could receive approximately:
CZK 500,000
The important point is that underinsurance doesn’t only affect situations where a property is completely destroyed.
Even a smaller claim may be reduced if the insured amount does not reflect the true rebuilding cost of your home.
How Can Underinsurance Happen?
Underinsurance usually isn’t caused by people deliberately choosing too little cover.
More often, it happens because the insured amount has not been updated as circumstances change.
Common reasons include:
- Construction costs have increased over time.
- You have renovated or extended your property.
- You have installed a new kitchen, bathroom, or other improvements.
- The original insured amount was estimated incorrectly.
- Your policy has not been reviewed for several years.
Over time, these changes can create a gap between what your insurance covers and what rebuilding your property would actually cost.
How Can You Avoid Underinsurance?
The simplest way to reduce the risk of underinsurance is to review your policy regularly.
You should consider checking your insured amount when:
- Construction costs increase significantly.
- You renovate or improve your property.
- You add valuable permanent features.
- Several years have passed since your last review.
A regular review helps ensure your insurance continues to reflect the real cost of protecting your home.
