Home insurance covers the cost of repairing or replacing your house when something goes wrong. When buying home insurance, price is important, but not everything. Focus on what you need, and what is (and isn't) covered by different policies.

Home insurance covers the building itself and the fixtures, for example, plumbing and built-in cabinetry. It can also cover legal costs if someone is injured on your property.

If you own an apartment or unit under a strata title, check with the body corporate to see if you need home insurance. The body corporate may be responsible for insuring the building. 

Contents insurance covers household items and personal belongings, such as furniture, televisions, clothes and jewellery. This can be bundled as home and contents insurance. If you're renting you only need contents insurance.

Getting the right cover with home insurance

When choosing home insurance, understand what the policy covers. This will help you compare policies and get the home insurance that best suits your needs.

Cover the cost of rebuilding your house

There are two main types of home insurance:

• Sum-insured cover — an estimate of how much it would cost to rebuild your home if it was totally destroyed.
• Total replacement cover — what it would cost to repair or rebuild your home to the same standard.

You're less likely to be underinsured with total replacement cover. However, not many insurers offer it and it's often more expensive.

To avoid being underinsured with sum-insured cover, check if your insurer offers a 'safeguard' or 'safety net'. This means they add up to 30% to your sum-insured amount in the event of a total loss.

Calculate the cost of rebuilding your house

Work out an accurate sum-insured amount to avoid being underinsured. Most insurers have calculators on their websites to help you do this.

Find a calculator that uses 'elemental estimating'. It will ask you for lots of details about your home, like:

• if your home is built on a slope
• the quality of internal fixtures and fittings
• when your house was built

Elemental estimating is more accurate than 'cost per square metre', which is a rough estimate based on the size of your house and the materials used.

Check if other expenses for rebuilding your house are covered, called 'supplementary costs'. For example, accommodation during rebuilding, and removing debris from the site.

Check the exclusions

Home insurance covers loss and damage caused by defined or insured events. These can include fire, flood, storm, theft and vandalism.

Check what events aren't covered. This could include damage caused by the sea, smoke, landslides or power failures.

Even if flood is included, damage to some parts of your house may not be covered. See storm, flood and fire insurance.

Adjust your excess

Most insurers allow you to adjust your excess. Weigh up the difference between having a low excess with a higher premium, versus the opposite. You may be able to save on your premium by increasing your excess.

Comparing home insurance

Get quotes from more than one insurer to find the best value and a policy that suits your needs. Compare the Key Fact Sheets of different policies. If you want more detail, read the product disclosure statement (PDS).

Compare these features:

Premium	cost for the same type of cover
Excess	amount you pay to make a claim option to reduce your premium by paying a higher excess
Exclusions	items and events not covered check for exclusions, caps, limits or other conditions
Legal liability cover	cover for injury to other people and their property at your home
Extended cover	adds extra to the sum-insured so you're not underinsured if there’s a total loss
Cover limits	maximum limit on how much you can claim for certain items

Renewing your home insurance

When it's time to renew your policy, check your level of cover. Take into account any changes you've made to your property. For example, landscaping, renovations, or a new pool may increase the cost of rebuilding.

Get quotes from a few other insurers to check you're getting the best deal. You may end up paying more by staying with your current insurer.
