Sum Insured

Home Insurance is based on the rebuild cost of your home. This is called your Sum Insured, and it will be the maximum we will pay to rebuild your home in the event of a natural disaster.

What do I need to do?

I'm an existing customer...

Renewing your policy? It’s a good time to check your Sum Insured figure each year when your policy comes up for renewal, to make sure it’s up-to-date and will still sufficiently cover the rebuild of your home. While your policy will include an adjustment for inflation, it won’t include any changes, additions or omissions to your property.

You will need to:

  1. Calculate your Sum Insured
  2. Contact us and let us know the new value

Sum Insured calculations

Every home is different and the rebuild cost will vary depending on a number of things, so it’s important you take the time to calculate a figure that is right for you.

As a homeowner, you are in the best position to know the details of your own home – so it makes good sense for you to determine your own rebuild cost. When calculating this cost, it’s important to take into account other items on your property, not just your house (for instance driveways, paving, fences, external garages and retaining walls). See ‘Things to consider’ for more information.
