Property insurance is a critical financial safeguard for commercial property owners. However, a concerning statistic shows that over 90% of commercial properties in Ireland are not insured for the correct amount. This widespread issue largely arises from a fundamental misunderstanding: the confusion between market value and reinstatement cost. Understanding the difference between these two valuation concepts is crucial for proper insurance coverage and avoiding significant financial risk.
Understanding Market Value: What Determines Property Worth?
Market value represents the price a willing buyer would pay a willing seller for a property in its current condition. This figure is influenced by numerous factors beyond the physical structure itself. A property’s location plays a significant role; properties in desirable areas command premium prices regardless of their construction costs. The surrounding amenities, proximity to business districts, transport links, and future development plans all factor into market valuation. For instance, a building located near a new public transportation hub might see its market value increase substantially.
Economic conditions heavily influence market values. During economic booms, property prices often rise rapidly, while during recessions, they may fall substantially—all without any physical change to the buildings themselves. Additionally, market value incorporates the land on which the property stands, which can constitute a substantial portion of the total value, particularly in urban areas where land is scarce. In Dublin, for example, land value can account for up to 60% of the total market value of a commercial property.
The property’s potential for development or alternative use also affects its market value. A commercial building situated on land with potential for residential development might have a market value far exceeding its value as a current commercial space. Supply and demand dynamics within specific property sectors further influence market pricing, creating fluctuations that have little connection to actual building costs.
Market value assessments typically involve comparing similar properties that have recently sold in the area, adjusting for specific differences between properties. Estate agents and property valuers specialize in determining these values for purchase, sale, or investment purposes.

Defining Reinstatement Cost: How Much to Rebuild?
In contrast, reinstatement cost refers specifically to the expense of rebuilding a property if it were completely destroyed. This value focuses exclusively on construction-related expenses and excludes the land value entirely, since land typically remains even after a catastrophic event like a fire or flood.
Reinstatement costs encompass several key components. First, there’s the expense of clearing the damaged structure and preparing the site for rebuilding, which can often amount to 5-10% of the total rebuild cost.. Then comes the cost of constructing a new building of the same dimensions, character, and function as the original, using current building materials and methods. The while online rebuild cost calculators can provide a rough estimate, you must account for all building elements, from foundations to roof, including mechanical and electrical installations.
Professional fees form another crucial component of reinstatement costs. These include fees for architects, structural engineers, quantity surveyors, and project managers who would oversee the reconstruction process. These fees can typically range from 10% to 15% of the overall construction cost. Planning application fees and building regulation compliance costs must also be factored in.
Importantly, reinstatement costs include VAT where applicable, which can add a significant percentage to the total figure. For commercial properties, the potential loss of income during the rebuilding period might necessitate additional business interruption insurance, though this is separate from the reinstatement cost itself.
Unlike market values, reinstatement costs change primarily with construction industry factors—labor rates, material costs, and building regulation requirements. The SCSI (Society of Chartered Surveyors Ireland) reports that construction price inflation in Ireland has reached 14% annually, with tender price inflation rising by 22% over the past 18 months due to pandemic effects, supply chain disruptions, and the Ukraine conflict. This rapid inflation underscores the need for regular reassessment of reinstatement costs.
The Critical Distinction: Why Market Value and Reinstatement Cost Matter for Insurance
The confusion between these two values creates serious financial risks for property owners. Insurance policies for buildings operate on the principle of indemnity—putting the insured back in the position they were in before the loss. Since rebuilding a property requires funding the construction work, not buying an equivalent property, insurance coverage should be based on reinstatement cost, not market value.
Insuring a property for its market value can lead to significant problems. If market value exceeds reinstatement cost, the owner pays unnecessarily high premiums for coverage they don’t need. Conversely, if reinstatement cost exceeds market value—common in areas with depressed property markets but high construction costs—the owner faces underinsurance.
The consequences of underinsurance become apparent through the “Average Clause” found in most property insurance policies. This clause stipulates that if a building is underinsured, any claim payment will be reduced proportionally. For example, if a property with a true reinstatement value of €1,000,000 is insured for only €600,000 (60% of its proper value), then any claim, regardless of size, may be reduced by 40%. Even a partial loss of €100,000 might result in a payment of just €60,000, leaving the owner to cover the shortfall. Studies show that, on average, underinsured properties receive 40-60% less in claim payouts than they should.
In today’s volatile construction market, underinsurance occurs easily if property owners don’t regularly update their insurance values. Post-pandemic supply chain issues, material shortages, and inflation have dramatically increased building costs, meaning valuations from even two years ago may now be significantly outdated. The cost of steel, for instance, has increased by over 30% in the last year alone.

Obtaining Accurate Reinstatement Cost Assessments: How to Ensure Proper Coverage
es. RICS (Royal Institution of Chartered Surveyors) regulated surveyors follow established methodologies for calculating these costs accurately. They consider regional variations in construction costs, current building regulations that might require enhanced specifications during rebuilding, and specific features of unique or historic buildings that may be more expensive to replicate.
The RICS recommends that commercial property owners commission a full on-site RCA every 3-5 years, with desktop reviews in the interim to account for inflation and changing building costs. This approach ensures that insurance values remain current and adequate. According to a recent RICS survey, properties with up-to-date RCAs are 85% less likely to be underinsured.
The Role of Professional Advisors: Insurance Brokers and Chartered Surveyors
Insurance brokers often recognize the importance of correct valuations but lack the specific expertise to calculate reinstatement costs themselves. Progressive brokers partner with surveying firms to offer their clients access to professional RCA services, recognizing that correct insurance values protect both the client and the broker’s professional reputation.
For property management companies overseeing multiple buildings, establishing a regular program of reinstatement cost assessments represents best practice in fulfilling their duty of care to clients. Many insurers now actively encourage or even require professional valuations as part of their underwriting process, especially for larger or more complex properties. Some insurers offer discounts of up to 10% on premiums for properties with a recent professional RCA.
Protecting Your Investment: The Importance of Understanding Reinstatement Costs
By understanding the fundamental difference between market value and reinstatement cost, and by obtaining professional assessments of the latter, property owners can ensure they have appropriate insurance coverage. This protects their financial interests, satisfies insurance policy conditions, and provides peace of mind that in the event of a catastrophic loss, they will have sufficient funds to rebuild without facing unexpected financial burdens.
In an era of volatile construction costs and complex building requirements, the investment in professional reinstatement cost advice has never been more important for responsible property ownership and management.
