What Are Multi-Vehicle Car Insurance Policies?

If you’re in a household with multiple cars, then you might want to consider taking out a multi-vehicle car insurance policy.

Technically, a multi-vehicle car insurance policy isn’t a specific type of car insurance. Rather, it involves bundling multiple vehicles onto one policy.

Anyone who has more than one vehicle in their house can typically qualify for a multi-vehicle policy, even if all of the vehicles don’t belong to you. Generally, the owners of the cars only need to reside in the same residence to qualify, and even then there are exceptions.

A commonly accepted checklist in the industry for adding multiple vehicles is as follows, although this will, of course, vary from provider-to-provider:

  • Single people with more than one vehicle
  • A couple with more than one vehicle
  • Friends, siblings and relatives who have more than one vehicle between them
  • Families (single parent and partnered) with children who are old enough to drive and own their own vehicles

The last point in this checklist is worth looking into, as there are some providers in the market who will allow you to bundle your cars onto a single policy even if your children live out of home.

Most of the providers that are eligible for Canstar’s Car Insurance Star Ratings will cover multiple vehicles, and we’d recommend you check the terms and conditions to see the various inclusions and exclusions.

The table below displays a snapshot of car insurance policies that can offer cover for multiple vehicles on Canstar’s database with links direct to providers’ websites. Please note this table has been sorted by Star Rating (highest to lowest) then by provider name (alphabetically) and was formulated based on a male aged 30-39 in NSW, without an extra driver under 25 years old.

Why have a multi-vehicle car insurance policy?

The main advantage of having a multi-vehicle car insurance policy is the convenience and potential savings they may offer. Some people find bundling all their household’s vehicles onto a single policy from the same provider simplifies the process as there’s just one set of paperwork and one payment that needs to be made.

In addition to this convenience, some insurers offer discounts for car-bundling, sometimes per-car! Progressive Direct, for example, surveyed 458 customers who switched to a multi-car policy in 2017 and discovered an average saving of $505.

There are some disadvantages of having a multi-vehicle car insurance policy. Depending on the number of cars listed, the premiums you have to pay could potentially be pretty intimidating. Younger drivers (like your children) or drivers with an extensive claims history may be resulting in higher premiums, due to the fact that research shows younger Australians are more likely to make claims going forward.

Some of the pros and cons of multi-car policies are summarised below:


  • You can expect to have one set of paperwork and one renewal date for multiple vehicles
  • Your insurer may offer you discounts, sometimes per vehicle
  • Your no claims bonus likely won’t be affected – each driver on the policy will still have their own claims history
  • New drivers and cars can be added at any time (in most cases)


  • You’ll potentially be faced with a large one-off insurance bill each year
  • Your premiums will be combined with the premiums of other drivers who may be seen as a bigger risk
  • The discounts on offer don’t automatically equal good value!

How many cars can you add to your policy?

This will depend on your provider, but typically multi-car policies offer cover for between two and five cars. This is done to target families or households, as getting multiple cars onto the one policy brings in more business. RACQ, for example, offers a 5% discount for any type of covered vehicle combined onto one policy.

Check the PDS document from your provider to see how many vehicles you can add. While most of the providers we rate will allow multi-car policies, not all of them will allow the same number of cars to be covered.

Remember, just because you’re getting a discount on your car insurance by bundling multiple cars, that doesn’t mean you’re getting good value – there could be cheaper yet more suitable options out there, so make sure you compare your options:

What other car insurance discounts are there?

Having multiple vehicles listed under the one policy isn’t the only way to get discounts on your car insurance. Some of the other more prominent methods are as follows…

  • Multi-policy discounts: these are discounts given to people who take out multiple different kinds of insurance policies (such as home and contents insurance) as well as car insurance with the same provider. Our database shows these discounts can be as much as 5-10% per policy.
  • No claims discounts: no claims discounts are offered by some car insurance companies to reward safe drivers with long periods between claims. These discounts vary between all 45 providers we rate, according to Canstar data.
  • Car alarm discounts: some insurers will give lower premiums to drivers that install safety features such as alarms on their cars, as these features can reduce their chances of theft and damage
  • Loyalty discounts: offered to reward customers that have stayed with one provider for a long time, these discounts are often tiered based on the length of your customer relationship with the insurer. For example, SGiO offers a loyalty discount as high as 25% for a customer of 25+ years with 10+ eligible policies.
