When you rent a car, you often face a decision about insurance. The rental company will offer you their own coverage options. These can seem straightforward, but they often come with a high price tag. Understanding what you need and what you already have can save you a lot of money. Rental companies are pushing more risk onto customers and charging record prices to buy it back at the counter pushing more risk onto customers.
Understanding Rental Car Insurance
When you rent a car, you’ll likely be offered a Collision Damage Waiver (CDW) or a Super CDW. These are not technically insurance policies. Instead, they are waivers that limit your financial responsibility if the car is damaged. The standard CDW often still has an excess, which is the maximum amount you would have to pay. Super CDW usually reduces this excess to zero or a very low amount.
The average daily cost of “Super CDW” has increased across most markets. Average excess liabilities have also climbed. This means the amount you could be liable for if you don’t take the rental company’s waiver is higher than before. In Australia, the average excess increased from AUD $4,982 to AUD $5,585 between 2024/25 and 2025/26 AUD $5,585. In Europe, the average excess rose to €2,155 €2,155.
If I were in this situation, I’d check my personal car insurance policy first. Many policies extend cover to rental cars, which could save me the cost of buying a waiver at the counter.
Why Rental Insurance Matters
The decision about rental car insurance can have a significant financial impact. The excess amounts can be very high, meaning a minor accident could cost you thousands. For example, in Australia, the average excess liability is now AUD $5,585 AUD $5,585. If you don’t have adequate cover, you could be responsible for this entire amount.
Rental companies are increasingly pushing more risk onto customers. They are also charging higher prices for their own insurance products. In Australia, Europcar almost doubled its daily Super CDW rate in one year Europcar almost doubled its daily rate. This makes it even more important to understand your options before you arrive at the rental desk.
Consider a scenario where you are driving in a foreign country. You might not be familiar with the local driving laws or road conditions. A small mistake, like a minor scrape in a car park, could lead to a large bill if you haven’t secured the right protection. This is why understanding the excess and the available cover is crucial.
What I’d want to do is ensure I have a clear understanding of the maximum I might have to pay. This helps me budget and avoid unexpected costs. It’s about peace of mind as much as financial protection.
Common Pitfalls with Rental Insurance
Accepting the First Offer
Many people accept the insurance offered by the rental company without question. This is often the most expensive option. Rental companies make a significant portion of their profit from selling these waivers. They are designed to be convenient, but convenience comes at a premium. The average daily Super CDW cost in Australia increased to AUD $53.21 AUD $53.21 per day.
Ignoring Existing Coverage
A common mistake is not checking if your existing insurance or credit card already provides cover. Many standard car insurance policies in the UK extend to rental cars. Some credit cards also offer rental car insurance as a perk. Failing to check this means you might be paying for cover you already have. This is a missed opportunity to save money.
Misunderstanding What’s Covered
Even when you buy a waiver, it’s essential to read the terms and conditions. Some waivers might exclude damage to certain parts of the car, like tires, windows, or the undercarriage. They might also have exclusions for driving on unpaved roads or in specific conditions. If an incident occurs that falls outside these terms, you could still be liable for the full cost of repairs. The rental company’s insurance is not always comprehensive.
Not Comparing Third-Party Options
There are specialist third-party companies that offer rental car excess insurance. These policies are often much cheaper than buying directly from the rental company. For instance, AXA Hong Kong & Macau launched a product offering rental car excess coverage up to HKD 42,000, which is around $5,376 coverage up to $5,376. If I were faced with this choice, I would compare the price and coverage of a third-party policy against the rental company’s offer. I’d want to see a clear saving and ensure the terms were comparable.

Checking Your Personal Car Insurance
Your own car insurance policy might already cover you for damage to a rental car. This is often the most cost-effective solution. You need to check the wording of your policy. Look for sections related to “driving other cars” or “temporary use of another vehicle.” Some policies may have limitations, such as the duration of the rental or the type of vehicle. Understanding these details is key to avoiding unexpected costs.
Leveraging Credit Card Benefits
Many credit cards offer rental car insurance as a benefit to cardholders. This can be a valuable perk, especially for frequent travellers. The coverage provided can vary significantly between cards. Some offer primary coverage, meaning you don’t need to claim on your own insurance first. Others offer secondary coverage, which kicks in after your personal insurance has paid out. Always verify the terms and conditions with your credit card provider before relying on this cover.
Exploring Third-Party Excess Insurance
Specialist providers offer rental car excess insurance as a standalone product. These policies are typically much cheaper than the waivers sold at the rental desk. They are designed to cover the excess amount you would otherwise be liable for. For example, one product offers personal accident protection up to HKD 120,000, or about $15,380 protection up to $15,380. When considering these options, compare the excess covered, any exclusions, and the claims process.
If I were renting a car abroad, my first step would be to get quotes from a couple of reputable third-party insurers. This usually provides a much better rate than the rental company’s offer, and I’d want to secure that saving.

Understanding Rental Company Waivers
If you decide to purchase a waiver from the rental company, understand the difference between CDW and Super CDW. A standard CDW will likely have a significant excess. The Super CDW aims to reduce this excess to zero or a very low amount. However, the cost can be high. In Europe, the average daily Super CDW cost is €30.82 €30.82. Always ask for a clear breakdown of what is covered and what the excess is.
