House Rebuild Calculator

This calculator will assist you in insuring your home. Remember that home insurance policies differ, some covering more than others; hence the importance of examining your policy carefully and insuring for the correct amount.

Please note that the Guide to House Rebuilding Costs for Insurance Purposes 2021 assists homeowners to insure their homes. The figures are guidelines based on speculatively built homes (housing estate homes). We recommend that you treat the figure provided within the calculator as a minimum for which you should insure the structure of your home. The guide is not intended for use for one-off properties.

For SCSI members wishing to print this document for valuation files, please note you will need to log into your account as this function is a benefit of membership.

Please Note: Insurance Rebuild Calculator

Please note that the SCSI guide is based on average minimum base construction costs figures from April 2021. The SCSI rebuild figures for 2022 will be released in the near future. Due to increased construction inflation rates over the last year, homeowners may decide to factor in the increase in construction inflation in the interim when renewing policies.


Please do not call the SCSI offices for insurance cost advice as we are not able to provide individual rebuild advice. If you need further assistance please search our database to find a building surveying or quantity surveying member near you that can provide professional advice.
