What is a No Claim Bonus?
A No Claim Bonus (NCB), sometimes called a No Claims Discount, is a reward offered by many Car Insurance providers in Australia to policyholders who don’t make a claim during their policy period.
The longer you go without lodging a claim, the bigger the discount you can earn on your Car Insurance premium. It’s a simple way insurers encourage careful driving while helping you save money.
How Does a No Claim Bonus Work?

The mechanics of a No Claim Bonus are straightforward, but there are a few details worth knowing to make the most of it. Here’s how it typically works:
- Earning the Bonus: Each year you hold a Car Insurance policy without making a claim, you build up your NCB. Most insurers use a rating system, often starting at Rating 6 (no discount) and moving up to Rating 1 (maximum discount) over several claim-free years.
- Discount Levels: The discount percentage increases with each claim-free year.
- Rating Protection: Many insurers offer an option to protect your NCB, meaning one at-fault claim won’t reset your discount. This usually comes at an extra cost but can be worth it for frequent drivers or those with high premiums.
- Transferring Your NCB: If you switch insurers, most will recognise your NCB history, provided you can supply proof (e.g., a renewal notice or a letter from your current insurer). This portability makes it easier to look around for better deals without losing your hard-earned discount.
- Claims that Affect Your NCB: Not all claims impact your NCB. For instance:
- At-fault claims (where you’re responsible for the accident) typically reduce or reset your NCB.
- Not-at-fault claims (where another party is liable) usually don’t affect it.
- Claims for events, such as hail damage, theft or vandalism, often won’t impact your NCB, but this varies by insurer.
A No Claim Bonus is a chance to keep your insurance costs down. By understanding how it works and what affects it, you can make smarter choices.
