The cost of car insurance is not determined solely by the choice of policy. Pricing is based on factors that most consumer articles only touch on: average claims costs by vehicle model, geographic segmentation, and how the deductible is factored into the premium. Understanding these mechanisms can help you negotiate a policy that suits your needs without paying too much.
Repair costs by model: the factor insurers weigh most heavily
Your insurance premium does not just reflect the likelihood of an accident. It also takes into account the average cost of each repair for the insured model. A vehicle with hard-to-find parts or bodywork that requires specialist procedures (aluminium bonding, ADAS sensor recalibration) can generate more expensive claims, even if accidents occur just as often.
Before taking out a policy, comparing potential repair costs with the vehicle’s residual value can make all the difference. For a model more than eight years old whose market value has fallen, a comprehensive policy with a low deductible can cost more in total premiums than the amount of a covered damage claim. In that case, it may be better to switch to an intermediate policy (extended third-party cover) while keeping theft and fire cover.
Owners of older or classic vehicles can also find insurance for a 306 convertible on Aide Auto, illustrating how each vehicle profile calls for a policy tailored to its actual value and specific risks.
Recycled parts offer a practical way to reduce costs. Their use in repairs approved by an assessor has increased in recent years, according to SRA data. Check whether your policy explicitly allows them: an insurer that accepts recycled parts can reduce the cost of a claim, which may help keep your premium down at renewal.

Car insurance deductibles: balancing the annual premium against out-of-pocket costs
Increasing your deductible is the most common advice for lowering your premium. The principle is simple: you agree to pay more out of pocket if you make a claim, and the insurer reduces your premium. The problem is that few drivers calculate the actual break-even point of this trade-off.
Take your claims history over the past five years into account. If you have not reported any damage, a high deductible (around €600 to €800) may make sense: the accumulated annual savings far outweigh the statistical risk of having to pay that amount yourself. However, a driver who makes a claim every two or three years may be better off keeping a moderate deductible.
- Fixed deductible: a set amount deducted from the payout, regardless of the claim cost. Better suited to frequent minor damage (parking incidents, light hail).
- Percentage-based deductible: a percentage of the claim amount, sometimes subject to a cap. Riskier for major claims, but often comes with a lower premium.
- Distance- or time-based deductible: included in some theft policies, it requires a waiting period or a certain distance to be met before cover applies. Read the policy-specific terms, not just the coverage summary.
The coverage summary displayed online does not always specify the type of deductible that applies to each item. Always ask for the policy-specific terms before signing.
Electric or hybrid vehicles: pitfalls of comprehensive cover
For a recent electric or hybrid vehicle, the policy name alone does not tell you what is covered. Damage to the high-voltage battery, onboard charger or charging cables is specifically excluded in many policies, including comprehensive cover.
Check three things before comparing quotes:
- Is the battery covered if it is damaged in an incident involving no identified third party (damage while parked, or hitting an obstacle in the road)?
- Is the deductible for electrical damage the same as for the rest of the vehicle?
- Does the policy set a specific reimbursement limit for high-voltage components?
Replacing the battery in a recent electric vehicle can account for a very significant share of the vehicle’s value. If the policy excludes this item or applies a disproportionate deductible, comprehensive cover may no longer be worthwhile. We recommend asking every insurer you contact for a battery-claim coverage estimate.

Canceling and switching car insurers: how the Hamon Law works in practice
After the first year of your policy, the Hamon Law allows you to cancel your mandatory car insurance at any time and switch insurers. Your new insurer handles the cancellation process and must ensure there is no gap in cover.
This does not guarantee an automatic reduction in your premium. Switching insurers is only worthwhile if you compare policies with strictly equivalent cover: the same deductible, the same payout limits and the same exclusions. Comparing only the advertised price without checking these three factors could leave you with less cover.
One often-overlooked point: when switching, make sure your statement of information is up to date and has been sent to your new insurer. This document summarizes your no-claims bonus and claims history over the past five years. An incomplete statement of information can lead your new insurer to place you in a higher risk category, wiping out the savings from switching.
One final technical point: if your premium increases despite no claims, check the tax breakdown on your renewal notice. Some recent increases are due to changes in the terrorism tax or contributions to the Guarantee Fund, rather than a reassessment of your risk profile by the insurer.
