One of the most common misunderstandings in property insurance is the difference between reinstatement cost and market value. They measure fundamentally different things, and confusing them can lead to serious underinsurance or overpayment of premiums.
Reinstatement cost is the amount it would cost to completely rebuild a property from scratch to its current specification. It includes demolition, site clearance, construction, professional fees, statutory fees, VAT where applicable and an allowance for inflation during the rebuild period. It does not include the value of the land. This is the figure that should be used as the buildings insurance sum insured.
Market value is what a willing buyer would pay for the property on the open market. It is influenced by location, land value, demand, comparable transactions and economic conditions. In London, market value is often significantly higher than reinstatement cost because of the high value of the land. In other areas, particularly for large commercial or industrial properties, reinstatement cost can exceed market value.
If a building is insured for its market value rather than its reinstatement cost, it may be over-insured in some cases (paying unnecessary premiums) or under-insured in others. Underinsurance is particularly dangerous because insurers may apply average, meaning they only pay a proportion of any claim. A regular professional reinstatement cost assessment ensures the sum insured is accurate.
A full reinstatement cost assessment should be carried out every three years and index-linked annually between assessments. It should also be updated after major alterations, extensions or changes of use. For residential blocks, managing agents should ensure the assessment is kept current as part of their duty of care to leaseholders.

Market value includes land value and is influenced by location and demand. Reinstatement cost is purely the physical rebuild cost. In London, market value usually exceeds reinstatement cost due to high land values.
The insurer may apply average, paying only a proportion of any claim. If insured for half the true reinstatement cost, you may only receive 50 percent of a claim.
