Choosing car insurance is about more than comparing monthly premiums. The true cost of a policy becomes clear when you make a claim, as the excess, coverage limits and exclusions determine how much you have to pay out of pocket. Understanding how these work helps you choose car insurance that genuinely suits your vehicle’s value and your budget.
Excess and out-of-pocket costs: the hidden cost of car insurance
Most guides compare third-party, third-party fire and theft, and comprehensive policies. This breakdown overlooks a factor that often has a greater impact on the final bill: the excess. According to SRA data cited by Boursorama in October 2026, car repair costs rose sharply between 2021 and 2025, driven by more expensive parts and onboard electronics.
Two policies with the same premium can leave you with very different out-of-pocket costs after an accident. A driver who chooses a high excess to reduce their monthly premium risks a sharp gap between the price they pay and the amount they have to shell out for a broken windscreen or a collision. Before signing, it is more reliable to compare your out-of-pocket costs after a claim than to look at the annual premium alone.

Third-party, third-party fire and theft, or comprehensive: a comparison of car insurance policies
The level of coverage depends directly on the vehicle’s value and how it is used. Here is a comparison of the three common policy types, their coverage and the drivers they are best suited to.
| Policy type | Coverage included | Suitable for |
|---|---|---|
| Third-party (liability) | Damage caused to third parties only | Older or low-value car, limited budget |
| Third-party fire and theft | Liability + theft, fire, glass breakage and weather events | Recent used car, daily urban use |
| Comprehensive | All the above coverage + damage to the insured vehicle (collision, vandalism, road departure) | New car, vehicle financed with a loan or lease |
A vehicle with a low residual value does not warrant comprehensive cover. Conversely, a new or financed vehicle calls for full damage cover, because the owner is repaying a loan on an asset that could be destroyed or stolen.
Electric or hybrid vehicles: coverage to check carefully
Repair costs after a collision vary depending on the powertrain. For an electric vehicle, replacing or repairing the high-voltage battery is a major expense with no equivalent in a combustion-engine model. Standard policy damage cover does not always cover this component beyond a certain limit.
Before taking out a policy for an electric or hybrid vehicle, check these three points in particular:
- The battery payout limit: some policies cap coverage at an amount below the actual replacement cost, which can account for a significant share of the vehicle’s price.
- Assessment procedures: an assessor without training in high-voltage technology may undervalue the damage or recommend replacement when a repair would suffice.
- Coverage for a home charging point: damage (power surge, fire) to a charging point installed at your home may be covered by your home insurance, your car insurance, or neither.
These differences between policies are rarely visible on an online comparison site. Reading the policy schedule is the only reliable way to identify them.
Natural disaster surcharge and weather events: two separate items on your policy
In October 2026, Le Journal de l’Économie reported that the surcharge funding the natural disaster scheme applicable to car insurance policies increased on 1 January 2025. This surcharge is mandatory and appears on every policy, regardless of the type of cover chosen.
It should not be confused with optional cover for weather events (hail, storms, flooding). The surcharge funds a national scheme, not your own coverage. A driver whose premium goes up may assume they are better protected against hail, when in fact only their contribution to the national fund has increased.
For actual protection against weather-related risks, check that “weather events” or “acts of nature” cover is included in your policy, with a clearly stated limit and excess.
Driver profile and no-claims bonus: what affects your car insurance premium
Your premium depends as much on the driver as on the vehicle. The no-claims bonus-malus coefficient (CRM) remains the most direct pricing factor. A driver who has not made an at-fault claim for several years benefits from a coefficient that significantly reduces their premium.
Other factors also come into play:
- Age and length of time holding a licence: young drivers pay an additional premium that gradually decreases over three years without an at-fault claim.
- Declared annual mileage: low mileage can significantly reduce your premium, provided you do not exceed the declared limit, or risk losing your cover.
- Where the vehicle is parked: a car kept in a locked garage costs less to insure than one parked on the street, especially in a densely populated urban area.
Accurately adjusting these details to reflect your circumstances, without underreporting them, helps ensure your premium matches the actual risk. Providing inaccurate information may result in a claim being refused, wiping out any savings from a lower premium.
Choosing car insurance comes down to balancing the type of cover, the excess and the driver’s actual profile. Comparing premiums without factoring in out-of-pocket costs after a claim means judging a policy by its label rather than its contents. Reading the policy schedule line by line remains the only way to genuinely protect both your budget and your vehicle.
