Rental car excess insurance is one of the most effective ways to reduce unexpected costs when hiring a vehicle. While many rental companies include basic insurance in their rental agreements, that protection often comes with a high excess. If the hire car is damaged or stolen, you could still be responsible for paying hundreds or even thousands of pounds before the insurer covers the remaining costs.
This is where rental car excess insurance becomes valuable. It reimburses some or all of the excess you pay following a valid claim, giving you greater financial protection and confidence when driving a rental vehicle.
In this guide, you’ll learn how rental car excess insurance works, what it covers, what it doesn’t cover, and whether it’s worth buying before your next trip.
What Is Rental Car Excess Insurance?
Rental car excess insurance is a separate insurance policy that reimburses the excess charged by the rental company if the hired vehicle is damaged or stolen during the rental period.
Most rental agreements include Collision Damage Waiver (CDW) or Theft Protection, but these policies usually require you to pay an excess if you make a claim. Excess insurance is designed to refund that amount, subject to the policy’s terms and conditions.
If you’re new to vehicle hire, our guide to what is rental car insurance explains how the different types of rental cover work together.
How Rental Car Excess Insurance Works
Understanding how excess insurance works is straightforward.
- You hire a vehicle from a rental company.
- The rental agreement includes basic insurance with an excess.
- If the vehicle is damaged or stolen, the rental company charges you the excess.
- You submit a claim to your excess insurance provider.
- If the claim meets the policy conditions, the insurer reimburses the excess you paid.
This allows drivers to avoid significant out-of-pocket expenses while still benefiting from the rental company’s primary insurance.
What Does Rental Car Excess Insurance Cover?
Although cover varies between providers, many policies include reimbursement for:
- Collision damage excess
- Theft excess
- Accidental vehicle damage
- Fire damage excess
- Vandalism-related excess
More comprehensive policies may also cover:
- Tyre damage
- Windscreen repairs
- Roof damage
- Undercarriage damage
- Lost or damaged keys
- Towing and recovery charges
- Administration fees charged by the rental company
Always review the policy wording carefully to understand the exact benefits.
What Isn’t Usually Covered?
Like any insurance product, rental car excess insurance includes exclusions.
Claims may be declined if:
- You breach the rental agreement.
- An unauthorised driver uses the vehicle.
- You drive under the influence of alcohol or drugs.
- The vehicle is used off-road where prohibited.
- Damage results from reckless or dangerous driving.
- You fail to report an accident as required.
Reading both the rental agreement and your insurance policy before travelling can help you avoid problems if you need to claim.
Rental Car Excess Insurance vs Rental Company Cover
Rental companies frequently offer excess reduction products at the rental desk. While convenient, these options can be considerably more expensive than purchasing an independent excess insurance policy before your trip.
Independent providers often offer:
- Lower overall cost
- Higher reimbursement limits
- Cover for multiple rentals
- Additional protection for tyres, windscreens, and keys
Comparing both options before you travel can help you find better value.
Who Should Consider Excess Insurance?
Rental car excess insurance may be particularly beneficial for:
- Holidaymakers hiring vehicles abroad
- Business travellers who rent cars regularly
- Drivers hiring premium or luxury vehicles
- Families taking road trips
- Anyone wanting to reduce unexpected financial risk
Do You Still Need Standard Rental Car Insurance?
Yes. Excess insurance does not replace the rental company’s primary insurance. Instead, it works alongside it by reimbursing the excess you are required to pay following a covered claim.

Can Credit Cards Cover Rental Car Excess?
Some premium credit cards include rental vehicle insurance or excess reimbursement as a cardholder benefit. However, eligibility, exclusions, and coverage limits vary considerably.
Before relying on this protection, check:
- Which countries are covered
- Vehicle type restrictions
- Maximum rental period
- Claim limits
- Whether payment must be made using the eligible credit card
Our upcoming guide on credit card rental car insurance explains these benefits in more detail.
Hiring a Car Abroad
Excess amounts can be significantly higher when hiring vehicles overseas. Before travelling, check whether your excess insurance covers international rentals and whether there are any country-specific restrictions.
The GOV.UK driving abroad guidance provides useful information about driving requirements in different countries.
Tips Before Buying Rental Car Excess Insurance
Compare Policies Carefully
Look beyond the premium and compare reimbursement limits, exclusions, and additional benefits.
Check Maximum Excess Limits
Ensure the policy covers the full excess charged by your rental company.
Review Vehicle Restrictions
Luxury, sports, commercial, and off-road vehicles may not be covered.
Understand the Claims Process
Keep copies of your rental agreement, payment receipts, accident reports, and photographs to support any future claim.
Common Mistakes to Avoid
- Assuming excess insurance replaces standard rental insurance.
- Buying duplicate cover without checking existing benefits.
- Ignoring country exclusions.
- Not reading the rental company’s terms and conditions.
- Failing to inspect the vehicle before collection.
Is Rental Car Excess Insurance Worth It?
For many drivers, the answer is yes. A relatively inexpensive excess insurance policy can protect against substantial excess charges if something goes wrong during the rental period. Frequent travellers and anyone hiring vehicles abroad may find it especially valuable.
Final Remarks
Rental car excess insurance provides an extra layer of financial protection by reimbursing the excess charged after a covered claim. Understanding what it covers, comparing providers, and checking your existing insurance can help you choose the right policy for your next hire. By preparing before you travel, you can enjoy greater peace of mind and avoid costly surprises if an accident or theft occurs.
