Since 2024, home insurance premiums have been increasing every year due to the combined effects of climate-related claims and the adjustment of the natural disaster surcharge. The average premium reached 323 euros excluding tax in 2025 according to France Assureurs, and increases are continuing in 2026. In this context, choosing a contract suitable for your home requires understanding a few mechanisms that are rarely detailed by online comparators.
Natural Disaster Surcharge and Home Insurance Budget: The Item No One Masters
The natural disaster surcharge, which increased from 12% to 20% on January 1, 2025, by ministerial order, represents a mechanical cost increase on each contract. Specifically, this tax applies to the damage guarantee, regardless of the insurer or the chosen plan.

This budget item is not subject to negotiation. Whether you choose a mutual insurance company, a bank insurer, or an online broker, the natural disaster surcharge is the same for equivalent coverage. The only variable is the amount of the damage guarantee on which it is calculated.
When you receive a quote, isolate this line. A contract displayed at a low price with a high damage guarantee may generate a heavier natural disaster surcharge than a slightly more expensive contract tailored to your actual needs. A tool that structures the comparison process, such as the site map for choosing your home insurance wisely, helps identify these items before requesting quotes.

Deductible in Home Insurance: The True Cost of a Claim
The deductible is the amount you are responsible for after a claim. Comparators display the annual premium, rarely the deductible. Two contracts at the same price can involve very different out-of-pocket costs in the event of water damage or fire.
Fixed or Proportional Deductible
A fixed deductible (for example, a specific amount in euros) is predictable. A proportional deductible (a percentage of the claim amount) can turn out to be much more expensive for a significant damage. Some contracts combine both depending on the type of claim.
The natural disaster deductible is regulated. For individuals, it remains distinct from the standard contractual deductible. Checking the deductible by type of claim is more revealing than comparing annual premiums.
In the Case of Water Damage and Climate Events
Water damage is the most common claim in home insurance. The deductible applied to this item varies significantly from one insurer to another. For climate events (storm, hail, snow), coverage is generally included in multi-risk contracts, but the compensation limits and deductibles differ.
Before signing, request a simulation of out-of-pocket costs for two or three concrete scenarios: minor water damage, broken glass after hail, theft with break-in. This approach provides a more reliable picture of the contract than merely reading the annual rate.
Home Insurance Cancellation: The Rules That Change the Game
The Hamon law allows for the cancellation of a home insurance contract at any time after the first year, without fees or penalties. The new insurer handles the procedures with the former one. This mechanism facilitates competition, but it remains underutilized.
Since 2023, cancellation in three clicks is mandatory for contracts taken out online. The insurer must offer a cancellation button accessible directly from the client area. In practice, feedback varies on this point: some insurers make the cancellation process less smooth than the subscription.
For tenants, home insurance is mandatory. Therefore, cancellation can only occur if a new contract takes over immediately. For owner-occupants, insurance is not legally mandatory (except in co-ownership for civil liability), but remaining without coverage exposes one to significant financial risks in the event of a claim.
Home Insurance Coverage: Distinguishing the Core from the Options
A multi-risk home insurance contract covers a minimal core:
- The personal liability, which covers damages caused to a third party by you or members of your household
- The fire, explosion, and water damage coverage, present in almost all basic plans
- The theft and vandalism coverage, often conditioned on protective measures for the home (certified lock, shutters)
- The climate events coverage (storm, hail, snow weight), distinct from the natural disaster coverage
Beyond this core, options differ according to insurers. Glass breakage coverage, legal protection, or replacement at new are items to evaluate based on the value of your home’s contents and your exposure to risks.
Assessing the Value of Household Contents
The declared household contents capital determines the amount of compensation. Underestimating this capital reduces the premium but exposes you to partial compensation in the event of total loss. Overestimating unnecessarily inflates the contribution.
A room-by-room inventory, even a rough one, allows for a realistic estimate. Keep invoices for valuable items: they speed up the claims process and limit disputes with the expert.
Tenant or Owner: Different Insurance Obligations
Tenants must provide a home insurance certificate to their landlord every year. Failure to have insurance can lead to lease termination. Non-occupying owners (PNO) have every interest in taking out specific insurance, even if the law only mandates it in certain cases of co-ownership.
Co-owners are required to take out at least civil liability coverage. The co-ownership syndicate has its own contract for common areas, but this contract does not cover the contents of your apartment.
The distinction between these statuses determines the type of contract to seek. An owner-occupant of a single-family home does not have the same needs as a tenant in an apartment, and the price differences reflect this reality.
With premiums structurally rising and deductibles varying by insurer, the choice of home insurance relies less on the displayed price than on the alignment between the coverage taken out and the actual risks of the home. Reviewing your contract every two or three years, comparing deductibles as much as contributions, remains the most reliable method to avoid unpleasant surprises at the time of a claim.
