Understand the risks of underinsurance and learn how to accurately value your assets to ensure your policy provides full protection when you need it most.
What is Underinsurance and Why is it a Key Consideration?
Underinsurance occurs when the sum insured on your policy is less than the actual cost to rebuild, repair, or replace your assets. This creates a gap between your level of cover and your potential financial loss, meaning a claim payout may not be enough to restore your property or business to its previous state.
In Australia’s dynamic economic environment, the costs associated with rebuilding property and replacing business assets can change significantly over time. Factors like fluctuating material costs, labour availability, and supply chain logistics all influence the true replacement value of your assets. Because of this, insurance policies that are not regularly reviewed can quickly become outdated, leaving asset owners unintentionally exposed.
The Difference Between Market Value and Rebuild Cost
Rebuild or replacement costs, on the other hand, are driven by the practical expenses required to reconstruct a building or replace an asset from the ground up. These include:
- Costs of building materials and specialised equipment
- Wages for skilled labour
- Demolition and site clearing expenses
- Professional fees for architects and engineers
- Council applications and compliance with current building codes
Replacement value is the total cost to recreate an asset from scratch in the current market.
Why Underinsurance is a Growing Concern
Ongoing economic shifts can affect the cost of both building materials and business assets. For business owners, the replacement cost of commercial machinery, specialised tools, and electronic equipment can increase, while supply chain issues can extend the time and cost associated with business interruption.
For businesses that hold stock, such as retailers or trades, fluctuating inventory levels can also create a risk. A sum insured based on an average stock level may be insufficient if a loss occurs during a peak period.
The Financial Impact: How Underinsurance Affects Your Payout
Many commercial insurance policies contain a provision known as an "Average Clause" or "Co-insurance Clause." This clause is designed to ensure that assets are insured for their full value. If you are found to be underinsured at the time of a loss, this clause can result in a claim payment being reduced proportionally.
This means that even for a partial loss, you may not receive the full amount claimed. The insurer calculates a payout based on the ratio of how underinsured you were.
How a Proportional Payout Works
The principle is that if you have only insured a percentage of the asset’s total value, the insurer will only pay the same percentage of your loss. The formula is typically:
(Sum Insured / True Replacement Value) x Amount of Loss = Payout Amount
Consider a commercial shed with a true rebuild value of $1,000,000.
| Scenario | Sum Insured | True Value | Level of Cover | Loss Amount | Insurer Payout | Your Shortfall |
|---|---|---|---|---|---|---|
| Correctly Insured | $1,000,000 | $1,000,000 | 100% | $200,000 | $200,000 | $0 |
| Underinsured | $800,000 | $1,000,000 | 80% | $200,000 | $160,000 | $40,000 |
As the example shows, being underinsured by 20% resulted in the claim payout for a partial loss also being reduced by 20%.
The Hidden Costs of a Shortfall
For a business, the financial consequences of a reduced payout can be significant. A shortfall in funds can impede the ability to repair premises, replace essential equipment, or replenish stock, delaying the return to normal operations.
When key assets covered by a business package insurance policy cannot be fully replaced, it can affect business continuity and revenue. In some circumstances, this can even lead to personal financial liability for business owners who need to cover the difference out-of-pocket.
Common Triggers for Underinsurance in Business and Property
Underinsurance often happens gradually and without notice. Several common business and property management activities can create a gap in cover if insurance policies are not updated accordingly.
- Property Upgrades: Failing to update policies after significant renovations or improvements.
- Asset Accumulation: Overlooking the cumulative value of tools, office fit-outs, or equipment acquired over time.
- Stock Fluctuations: Inaccurate stock valuations that don’t account for seasonal peaks.
- GST: Forgetting to include GST in replacement cost calculations, which can be a significant oversight for entities not registered to claim input tax credits.
Property Upgrades and Renovations
When you add a new mezzanine to a warehouse, complete a significant office fit-out, or extend your commercial premises, you increase the property’s replacement value. It’s a common mistake to assume that standard policy indexation will cover these capital improvements. A policy review is essential to ensure the new, higher value is reflected in your sum insured.

Asset Accumulation in Trades and Construction
For tradespeople and construction businesses, tools and machinery are vital assets. As a business grows, it naturally accumulates more equipment. A new vehicle, an upgraded diagnostic tool, or a second set of specialised gear can quickly increase the total value of your business contents.
Relying on second-hand or depreciated values for insurance is incorrect; the sum insured should reflect the cost of replacing items with new equivalents. Maintaining an up-to-date asset register is a crucial step in ensuring your construction and trades insurance limits remain adequate.
Practical Steps to Ensure Your Cover Matches Your Replacement Costs
Proactively managing your sums insured is the most effective way to protect against underinsurance. This involves a methodical approach to valuing your assets and regularly reviewing your policy.
- Engage Professionals: For buildings, a formal valuation from a qualified quantity surveyor provides the most accurate assessment of rebuild costs.
- Use Calculators as a Guide: Reputable online building cost calculators can offer a useful starting point for initial estimates.
- Account for Supplementary Costs: Ensure your calculations include allowances for all aspects of a rebuild, not just the construction itself.
- Conduct Annual Reviews: Make it a habit to review your insurance policy at least once a year with your broker to adjust for inflation, asset changes, and business growth.
Supplementary Rebuild Costs to Consider
A basic calculation of cost-per-square-metre is rarely sufficient. A comprehensive valuation should also factor in other potential expenses, though coverage for these items will depend on your specific policy wording.
- Demolition and Debris Removal: This can be a substantial cost, particularly after a major event like a fire or storm.
- Compliance with Modern Standards: A rebuild must adhere to the current Australian Building Codes and local council requirements, which may be stricter than when the original structure was built.
- Professional Fees: Costs for architects, surveyors, engineers, and project managers are often a necessary part of the rebuilding process.
Reviewing Your Sums Insured
A thorough audit of your business contents, stock, and other assets is fundamental. Indexation, an automatic increase in your sum insured applied by some insurers at renewal, can be helpful but may not keep pace with sharp rises in costs or significant changes to your business. It is always important to notify your broker of any material changes to your operations or assets.

Frequently Asked Questions
What is the "average clause" in an insurance policy?
The average or co-insurance clause is a policy condition that can reduce your claim payout if your assets are insured for less than their full replacement value. The payout is reduced in proportion to the amount of underinsurance.
Does market value affect how much I should insure my building for?
No. Your sum insured should be based on the full rebuild cost of the building, not its market or sale value. Rebuild costs include materials, labour, fees, and demolition, which are unrelated to real estate market prices.
How often should I review my business insurance sums insured?
It is advisable to review your sums insured at least annually at renewal. You should also conduct a review whenever you make significant changes, such as purchasing new equipment, renovating your premises, or substantially increasing stock levels.
Is debris removal included in my building sum insured?
This depends on your policy wording. Some policies include a specific, separate benefit for debris removal, while others expect it to be factored into the total building sum insured. It’s an important cost to account for.
Can underinsurance affect my public liability claim?
Underinsurance typically relates to property and asset policies. A public liability claim is based on your legal liability for personal injury or property damage to a third party and is not directly affected by the valuation of your own assets.
What happens if building costs increase during my policy period?
Some policies include an "escalation clause" or "inflation adjustment" that automatically increases your sum insured by a set percentage throughout the policy period to provide a buffer against rising costs. Check your policy to see if this feature is included.
Are professional fees covered in a standard property policy?
Fees for architects, surveyors, and engineers are often required for a major rebuild. Whether these are covered depends on your policy. They may be included as an additional benefit with a sub-limit or need to be factored into your overall sum insured.
Why is inflation a risk for my insurance coverage?
High inflation directly increases the cost of materials, labour, and transport. If your sum insured doesn’t keep pace with these rising costs, you can easily become underinsured without making any changes to your property or assets.
