Canstar Data Insights Director, Sally Tindall says, “It’s understandable that drivers are looking for ways to reduce the cost of their cover, but it’s critical to understand when the savings are wise and when they carry serious risks.”
“Some steps, such as paying your premium annually and comparing your options every year, could save you money without compromising on cover.
“However, it’s important to know where to draw the line. Underestimating your kilometres or removing regular drivers from your policy might seem harmless, but if you need to make a claim, it could have consequences that outweigh any savings from a lower premium.
“If you don’t drive often, you may be eligible for a low-kilometre discount. However, accurately reporting your mileage is often required to qualify for these discounts.
“While many policies cover unlisted drivers, this depends on the insurer and the specific terms of a policy. Some insurers will charge you a higher excess if you weren’t driving when the accident occurred.
“Another cost-cutting tactic is to downgrade from comprehensive cover to third-party property. While this will deliver noticeable savings upfront, it offers no protection for your own car if you’re at fault in an accident, potentially leaving you with significant out-of-pocket repair costs, or worse, being left without a car altogether.
“For drivers looking to cut costs without sacrificing protection, switching insurers can be a straightforward way to achieve this. While your annual renewal notice is a good opportunity to compare prices, don’t let it be a roadblock to savings if you want to switch sooner. Drivers may not realise you can usually switch at any time, although some insurers may charge a cancellation fee for ending a policy early.
“As with all insurance, check the fine print of your new policy before you switch to make sure you’re covered for everything you expect in your insurance.”
