Here's a helpful hint

When looking for total replacement cover in your home insurance, you can either get a policy that has "full building replacement", or you can provide the insurer with an estimated sum insured amount during the quote process. This is sometimes called "total rebuild costs". If you do this, it's a good idea to get your home evaluated to avoid underinsuring your home.

What is total replacement home insurance?

Total replacement cover is home insurance that covers the cost of rebuilding your home to the state it was in prior to an insured event. If your home is damaged by an insured event, the insurer will either rebuild it to its previous state or pay you the assessed cost to rebuild it to its former condition.

These types of policies reduce the gap between the amount your home is insured for and what it actually costs to repair or rebuild the home to its original condition.

Only a few home insurers offer total replacement cover, as it provides a higher level of protection than ordinary home insurance policies. It also tends to have higher premiums.

Total replacement cover vs sum insured cover

There are two main types of home insurance available: total replacement cover and sum insured cover. Sum insured cover allows you to nominate the maximum amount of cover you want for your home. For example, if you think your home will cost $1,000,000 to rebuild from scratch, you would insure it for $1,000,000. If your home is completely destroyed by an insured event, the insurer will then pay a benefit up to that set limit.

How does it differ from total replacement cover? Well, total replacement insurance covers the market value of rebuilding your home, whereas sum insured cover makes it your responsibility to decide how much your home will cost to rebuild. If, for example, you're insured for $1,000,000 but your home ends up costing $1,200,000 to rebuild, you'll be $200,000 out of pocket.

How to calculate the replacement cost of your home

According to the Insurance Council of Australia, 83% of Australian homeowners and renters are underinsured. To make sure you have the right amount of home insurance, there are two main methods for working out the cost:

  • Cost per square metre. This is a basic method and is based on the size of the house and the materials it's made of, so it can't be relied upon to provide an accurate figure.
  • Elemental estimating. This is a much more sophisticated method that takes into account a range of factors, including local wage rates, material costs, the quality of the finishes used, the nature of the building site, how many levels the home has, council approval fees and more.

Using online calculators

To help you work out how much cover is enough for your home, many insurers offer handy online calculators. However, rather than taking the figures quoted by these calculators at face value, try to look for a calculator that takes into account current building and replacement costs to help you reach a more accurate sum insured.

This calculator from the Insurance Council of Australia is a great place to start.

Is total replacement home insurance right for me?

The biggest benefit of total replacement cover is that it greatly reduces the risk of underinsurance. Rather than having to rely on your own (perhaps limited) knowledge to decide on a suitable amount of cover for your home, these policies provide the peace of mind of knowing that you will be able to afford the repair or rebuilding costs if disaster strikes.

However, there are a couple of key disadvantages that you should be aware of before purchasing cover:

  • Higher cost. Total replacement cover is usually more expensive than sum insured cover.
  • Delayed payment. You might have to wait a little longer to receive the funds from a total replacement policy, as the insurer will need to complete a thorough assessment to work out the total cost of rebuilding your home.

It’s also important to remember that sum insured policies shouldn’t be dismissed outright just because of the risk of underinsurance. If you’re willing to spend a little time calculating the approximate rebuilding costs for your home, you’ll stand a much better chance of choosing an appropriate level of cover. Many policies also offer a “safety net” that can provide up to 30% additional cover on top of your sum insured if your home is declared a total loss.

Regardless of whether you choose total replacement or sum insured home insurance, it’s essential that you shop around before you commit to any one policy. By comparing the features and costs of a range of policies, you’ll find the best value for money for your individual circumstances.
