Moving house does more than change your address. It can change your insurance premiums as well.
Insurers assess risk based on postcode, property type and personal circumstances. Even relocating a few streets away can increase or decrease what you pay.
Here are six common reasons your home and contents or car insurance may change when you move.
Location factors affecting home and contents insurance
1. Natural hazard risk
Your new suburb’s exposure to natural hazards plays a major role in your premium.
Insurers assess flood zones, bushfire risk, cyclone exposure and storm history when pricing policies. In recent years, extreme weather events across Australia have increased rebuilding costs and influenced how insurers calculate risk.
If you move to a higher risk postcode, your premium may increase. If your new area has lower exposure, you could pay less.
Always check whether flood cover is included automatically or offered as an optional extra.
2. Home security
Crime statistics in your new suburb can also affect pricing. Areas with higher rates of theft or vandalism may attract higher premiums.
Security features can help reduce risk. Insurers may take into account:
- Monitored alarm systems
- Deadlocks on doors and windows
- Security screens
- Lockable garages
Upgrading security may not dramatically reduce your premium but it can improve your overall protection.
3. Age and structure of your new property
The age, construction type and condition of your new home influence how it is insured.
Older properties may have outdated wiring or plumbing which can increase risk. Construction materials such as brick, timber or concrete affect how well a property withstands fire, storms or impact damage.
Rebuilding costs have risen significantly due to higher labour and material prices across Australia. When moving, review your sum insured carefully to ensure it reflects current replacement value rather than the market value of the property.
Location factors affecting car insurance
1. Your neighbourhood
Your car insurance premium is also influenced by postcode.
Insurers assess local accident frequency, theft rates and claim history in your area. Even moving a short distance can change your suburb’s risk profile.
If your new area has a lower accident rate or lower vehicle theft statistics, you may see a reduction in premium.
2. Where you park your car
Where your car is kept overnight affects risk.
Parking in a locked garage is generally viewed as lower risk than street parking. Even secure off street parking such as a private driveway can make a difference.
If your new home offers improved security for your vehicle, notify your insurer as this may positively affect your premium.
3. How far you drive each year
Your annual kilometres travelled also matter.
Some insurers offer lower premiums for low kilometre drivers. If your new home is closer to work, school or public transport, you may drive less each year and qualify for adjusted pricing.
Be realistic when estimating annual kilometres. Underestimating could affect a future claim.
