Reinstatement Cost Assessments
Clear, professional advice to help commercial property owners insure their buildings accurately and avoid unnecessary risk.
A Reinstatement Cost Assessment (RCA) provides an independent, evidence-based assessment of the cost of rebuilding a commercial property and its contents in the event of total loss. It forms the basis for setting appropriate levels of building insurance, ensuring cover reflects the true cost of reinstatement.
We provide Reinstatement Cost Assessments for commercial property owners, delivering clear advice that helps protect against underinsurance or unnecessary premium costs.

When and Why a Reinstatement Cost Assessment Is Needed
For commercial property owners, ensuring buildings are insured to the correct reinstatement value is essential to managing risk.
A Reinstatement Cost Assessment calculates the cost of rebuilding the property as new, including demolition, professional fees and statutory costs. This figure often differs significantly from market value or purchase price.
RICS guidance recommends that Reinstatement Cost Assessments are reviewed regularly, typically every three years, or sooner where buildings have been altered, extended or refurbished. Without an up-to-date assessment, owners may be exposed to underinsurance, leading to reduced insurance payouts in the event of a claim.
Equally, over-insuring a property can result in unnecessarily high premiums without any additional benefit. A properly prepared assessment provides clarity and supports informed discussions with insurers and advisers.
How We Support Property Owners
Our role is to provide clear, defensible reinstatement values that reflect the specific characteristics of each building.
