MAINTAINING A HOME
Avoiding underinsurance: What to consider when buying home insurance
02 March 2020
If the unexpected struck and your home was damaged or destroyed, would you have enough home insurance to start from scratch?
How much coverage will you need to protect your home?
About four out of five Aussie homeowners don’t think they have enough insurance to resume their normal standard of living if their property was badly damaged or destroyed.1 So, how do you know if there’s a gap in your coverage? It’s about understanding exactly how much of it you need.
Sum insured cover
Sum insured cover is the most common type of home building insurance in Australia. To calculate a sum insured for your policy, you’ll let your insurer know how much cover you need when you take out or renew it. If your insurer agrees, that amount will be your sum insured, and your premiums will be determined accordingly.
To arrive at this figure, you’ll have to work out what it would cost to rebuild your home. Two ways of doing this are:
- Estimating the cost per square metre to rebuild. Though this sounds straightforward, it could put you at risk of underinsurance because it assumes an average cost rather than the actual rebuilding cost.
- Something called “elemental estimating”. This method, borrowed from the construction industry, takes into account other considerations you might make when it comes to your rebuild, such as fancy finishes and materials, or unexpected costs.
The unexpected costs of rebuilding
If your home is beyond repair, insurers will classify it as a “total loss”. This may mean you’ll be hit with additional costs, which are useful to factor into your sum insured. These can include:
- increased construction and material costs (eg after a community-wide event like a bushfire or a flood)
- the need to comply with new building codes
- the location of the property (ie the specific address, not just the postcode)
- the slope of the land (sloping land is usually more expensive to build on)
- the construction style (eg a historic building may cost more to build)
- the cost of removing debris, or
- the cost of temporary accommodation while you rebuild.

If you’re building from scratch, you’ll probably need to apply to your local council for permits. You’ll also need to account for architect, builder or surveyor fees. Chat to someone who knows their stuff, like a builder or an architect, in advance of calculating how much insurance you need. That way, you’ll know how much to include in your sum insured for these extra fees.
When you’re considering insurance for your home, think about whether you’d like to cover the things inside it as well.
To work out the right amount of cover for your contents, you need to understand how much they’re worth. If you add new items to your sum insured as you buy them, especially valuable stuff like appliances and electronics, you’re less likely to wind up underinsured.
