Property Rebuild Costs for Insurance
The rebuild cost of a property is the amount it would cost to completely reconstruct your home from the foundations up if it were destroyed. This figure is crucial for buildings insurance as it determines how much coverage you need. Unlike market value, which includes the land and location factors, the rebuild cost focuses solely on construction expenses.
The Building Cost Information Service (BCIS), part of the Royal Institution of Chartered Surveyors (RICS), provides authoritative data on rebuilding costs. Their calculator helps homeowners estimate these costs based on property type, size, location, and features. Accurate rebuild cost assessments ensure you're neither underinsured (risking financial shortfall after a claim) nor overinsured (paying excessive premiums).
For listed buildings, properties of non-standard construction, or homes with unique features, professional surveyor assessments are recommended as online calculators may not provide sufficient accuracy.
How to Use the BCIS Rebuild Cost Calculator
Step 1: Enter Property Type and Basic Details
Select your property type from the dropdown menu (detached, semi-detached, terraced, or bungalow). This classification affects the base construction cost used in calculations.
Step 2: Provide Accurate Measurements
Enter the external floor area in square meters. For multi-story buildings, measure the footprint and multiply by the number of floors. Accurate measurements are crucial for a reliable estimate.
Step 3: Specify Property Characteristics
Select the number of storeys, bedrooms, property age, and construction quality. These factors influence the complexity and cost of rebuilding your home.
Step 4: Select Your Region
Choose your property's location from the dropdown menu. Construction costs vary significantly across different regions of the UK, with London typically being the most expensive.
Step 5: Review and Use Your Estimate
After clicking "Calculate Rebuild Cost," review the detailed breakdown showing how your estimate was calculated. Use this figure when arranging buildings insurance, but consider professional assessment for unusual properties.
