Rebuild Insurance Cost Assessment – Optional Survey Add-On

A Rebuild Insurance Cost Assessment (Reinstatement Valuation) is an optional supplementary service available alongside our Level 2 Home Surveys and Level 3 Building Surveys. It provides an indicative estimate of the property's likely rebuilding cost for buildings insurance purposes, helping you establish an appropriate insurance sum insured when purchasing a property.

​

This calculation is offered as an addition to our core residential surveying services, rather than as a standalone valuation service. It uses information gathered during the property inspection, together with current BCIS residential rebuilding cost data, to produce an estimated rebuilding figure based on the property's characteristics.

​

Why an Accurate Rebuild Cost Estimate Matters

Buildings insurance should be based on an appropriate estimate of rebuilding cost, rather than the property's purchase price or market value.

​

If the declared figure is too low, the property may be underinsured, potentially leaving the owner financially exposed following a significant claim.

​

Rebuilding costs also change over time. Construction labour, materials and professional fees respond to market conditions, while changes to Building Regulations can affect the cost of rebuilding older properties. Relying solely on a historic figure or annual index-linking may not always keep cover adequate.

​

What Does the Additional Calculation Include?

We review the available information about your property and apply the relevant BCIS residential rebuilding cost data to produce an estimated rebuilding figure.

Depending on the property, this may include allowances for:

• Demolition and site clearance;

• Removal and disposal of damaged or contaminated materials;

• Professional fees, including architects', surveyors' and engineers' fees;

• Compliance with current Building Regulations and other statutory requirements;

• Construction, labour and material costs; and

• External works and landscaping, where appropriate.

​

The precise items included depend on the property and the methodology and assumptions used.

The calculation provides a practical indication of rebuilding cost for buildings insurance purposes. It may be useful when arranging insurance following a property purchase or reviewing an existing sum insured.

​

Important: An Indicative Estimate, Not a Full Reinstatement Cost Assessment

This calculation is based on a limited range of property information and standardised BCIS residential rebuilding cost data. It does not involve detailed measurement and valuation of every building element.

​

It should therefore be treated as an indicative estimate rather than a definitive, fully property-specific reinstatement cost assessment. This supplementary service is not a standalone reinstatement valuation and is not a substitute for a full professional reinstatement cost assessment where one is required.

​

Rebuild Cost Is Not the Same as Market Value

A common misconception is that buildings insurance should be based on a property's market value. These are two different figures:

• Market value reflects what a property might reasonably sell for.

• Rebuild cost reflects the estimated cost of reconstructing the property following a total or substantial loss.

In areas with high land values, rebuilding cost can be substantially lower than market value. Conversely, properties with unusual construction, complex architectural features, difficult access or specialist materials may carry a comparatively high rebuilding cost.

​

Is This Additional Service Suitable for Your Property?

The calculation is primarily intended for standard residential properties, such as houses, bungalows and flats of conventional construction, where rebuilding costs can be reasonably estimated using standard BCIS residential rebuilding cost data.

It may not be appropriate for:

• Listed or historic properties;

• Properties of unusual or non-standard construction;

• Properties with significant or unusual architectural features or specialist materials;

• Properties with extensive alterations or extensions that could materially affect rebuilding costs; or

• Non-residential properties.

For properties in these categories, we recommend obtaining a full professional reinstatement cost assessment, which provides a more detailed and property-specific basis for determining the appropriate buildings insurance sum insured.

An Optional Addition to Your Level 2 or Level 3 Property Survey

Our core services are RICS Level 2 Home Surveys and Level 3 Building Surveys. If you are instructing us to survey a property, you can also request a Rebuild Insurance Cost Assessment as an optional addition.

The calculation is prepared using information gathered during the property inspection and can be included alongside your survey report, providing an additional indication of the rebuilding cost for buildings insurance purposes.

​

This service is available in conjunction with a Level 2 Home Survey or Level 3 Building Survey and is not offered as a standalone instruction. Where applicable, this additional service will be offered as an optional add-on during the quotation process, allowing you to include it alongside your Level 2 Home Survey or Level 3 Building Survey
