What happens if your home is underinsured?

If your home is underinsured, it means the value of your insurance policy doesn’t cover the costs it would take to replace it. In essence: your coverage isn’t enough.
This can leave you vulnerable to bigger bills and higher costs when the worst happens, such as flooding or bushfires.
According to Mozo banking expert Peter Marshall, underinsurance can deliver a massive blow to homeowners’ wallets when they need help the most. This is especially crucial to consider nowadays, as more and more people compromise on coverage to keep premiums down.
“Underinsurance is dangerous because many homeowners probably don’t even know that they are underinsured, then when it comes time to make a claim, they find themselves out of pocket,” says Marshall.
“Owning a property is a huge investment, not to mention everything that comes with it, like appliances, furnishings and all your belongings. Leaving it unprotected or only partially protected is a big financial risk.”
Unless your policy has underinsurance protection or total replacement cover, you’ll have to make the difference with your money.
How to avoid underinsurance and work out how much home insurance you need
You can take a few strategies to ensure your home & contents insurance adequately protects your property.
- Get a property valuation. Unless you’ve kept diligent receipts, it can be challenging to pinpoint the cost of replacing your home and everything inside. Get a professional property valuation to estimate how much cover you may need. Some home insurance policies also use smart technologies like AI to calculate the value of your home, such as Honey Insurance, which can make avoiding underinsurance simpler.
- Compare home insurance policies. Most Australians don’t take the time to research and compare home insurance policies. It’s easier to switch than you think! Make sure to read the product disclosure statement (PDS) and send for a quote so you can get an idea of what value is on offer.
- Opt for underinsurance protection. If the value of your home is liable to change during your coverage, you may want to opt for a policy with underinsurance protection. This clause acts as a safety net and insures your home for up to 30% more than the agreed-upon value in case you find yourself short of the rebuild costs.
- Go for value, not price. Insurance that doesn't adequately cover your property and belongings isn't worth the money, no matter how cheap (or expensive) the premium is. Instead, balance your coverage needs with your budget, instead of letting your budget have the last word.
