Reviewing your sum insured

We’ll adjust the sum insured before we renew your policy each year to make sure your cover keeps up with changes in building costs. To do this we’ll either use the Cordell Sum Sure calculator or we’ll use the building components of the consumer price index as a reference.

The new sum insured amount will be included in your renewal documents, which will be sent to you a few weeks before your policy renews. You need to review the sum insured each year to make sure it’s still enough to rebuild your home. The Cordell Sum Sure calculator can help you with this.

Full replacement for fire

One of the major causes of total house loss is fire. This benefit gives you peace of mind that we’ll rebuild your home even if it costs more than your sum insured. Policy terms and conditions apply.

This is one of the great benefits you can get with a Tower house insurance policy.

Present day value policies are an exception

Some houses will be insured for present day value, rather than sum insured. You can check your certificate of insurance to see if this applies to your home. Generally these are pre-1950s houses that haven’t been fully re-lined, re-wired or re-roofed. If you have completed these upgrades give us a call to see if we can offer you full replacement cover.

If your home is insured for its present day value, you’re covered for the market value of the house at the time of the loss or damage (excluding the value of the land), or the sum insured, whichever is less.
