Reinstatement Cost Assessments (RCAs) - RICS Building Surveyors London | Nassars Surveyors

Reinstatement Cost Assessments (RCA)

Accurate, RICS-compliant valuations that protect your property and your policy.

A Reinstatement Cost Assessment (RCA) is one of the most important yet often overlooked aspects of property management. At Nassars Surveyors, we provide precise, evidence-based valuations to ensure your property is correctly insured, not underinsured, not overinsured, but fully protected in the event of a loss. We act for freeholders, resident management companies, managing agents, and insurers, carrying out RCAs for individual buildings and entire portfolios across London and the UK. Our assessments follow RICS guidance and are completed with the same accuracy and professionalism that define all our services.

Why a Reinstatement Cost Assessment Matters

Insurance policies are only as strong as the reinstatement value behind them. An inaccurate valuation can lead to significant financial risk with underinsurance leaving you exposed, and overinsurance wasting money on excessive premiums. We make sure your reinstatement value reflects current building costs, materials, and site conditions, helping you make informed, compliant, and financially sound decisions. Our goal is simple. To give you confidence that your property is insured for exactly what it would cost to rebuild, no more and no less.

Our Approach

Each assessment is detailed, compliant and practical, carried out with precision and clear reporting.

1. Inspection and Data Collection

We inspect the property, reviewing construction type, age, condition, and location.

2. Measurement and Cost Calculation

Using the latest RICS cost data, BCIS indices, and our own market experience, we calculate a reinstatement figure specific to your property.

3. Adjustments and Specialist Considerations

We factor in demolition, professional fees, access, heritage constraints, and inflation to ensure a complete, defensible value.

4. Reporting and Advice

We provide a clear, easy-to-understand report with recommendations for insurance and review cycles, typically every three to five years.

When You Should Update Your RCA

You should update your reinstatement cost assessment:

We also offer portfolio RCAs, providing consolidated reports and guidance for property groups or managing agents overseeing multiple buildings.

Common Causes of Underinsurance

Underinsurance is a common issue in property management and can have serious financial consequences. Our experience shows that many buildings are underinsured for reasons such as:

Outdated or historic valuations that no longer reflect current costs.
Major refurbishment or extension works not included in the last assessment.
Rising construction costs and material price inflation.
Inaccurate square footage or omitted ancillary structures (garages, outbuildings, etc.).
Excluding demolition, debris removal, or professional fees from the calculation.

We help clients avoid these pitfalls through accurate, up-to-date, and fully compliant reinstatement assessments.
