When taking out a high value home insurance policy, it’s vital that you know what the re-building costs of your home are. The market value of your home does not correlate to the re-building costs so you should always have it surveyed wherever possible.
The best course of action is to hire a member of the Royal Institution of Chartered Surveyors to a do survey of your property. The surveyor will be able to prepare a Rebuilding Cost Assessment for you, which you can then provide your insurer to make sure that your policy covers the full re-building costs.
If for whatever reason you cannot hire a professional surveyor, then you can use the Building Cost Information Service (BCIS) of the Royal Institution of Chartered Surveyors (RICS). Click here to go to the calculator.
