For several weeks, many departments have been placed on red or orange alert for floods. The overflows continue, affecting both city centers and residential areas. This repetition of extreme episodes permanently modifies the risk assessment.
Departments on alert and flood zones
Next to 47% of French municipalities have at least one flood zone. This represents around 17 million inhabitants exposed, sometimes without being fully aware of it at the time of purchase or rental.
Areas close to major rivers or the coast are particularly monitored. But rapid floods linked to intense rains now also affect historically less exposed areas.
Increasingly costly natural disasters
Floods are among the most expensive weather events for insurers. The average cost per affected household often fluctuates between 10,000 and 14,000 eurosaccording to industry estimates.
On a national scale, the annual bill can amount to billions of euros when several major episodes combine. This financial pressure weighs directly on the balance of the compensation system.
Beyond homes, floods also disrupt transport, businesses and administrations. This multiplication of disasters creates a context where the question offlood home insurance becomes central for households.
Home and flood insurance what you will pay
Faced with the increase in claims, insurers are adjusting their risk models. Result: premiums could increase by 8 to 11% on average in 2026, with disparities depending on the most exposed regions.
The companies explain that they do not pass on the full costs to policyholders. However, the bonus remains a direct lever to absorb the billions of euros paid after each major episode.
In areas classified as at risk, certain specific increases may be added. Conversely, less exposed territories could experience more moderate increases.

Owner or tenant are you really covered?
Whether you are an occupant or a lessor, home insurance is compulsory in most situations. But not all guarantees are equal, especially when faced with the risk of flooding.
Natural disaster guarantee how it works
Compensation is based on official recognition of the state of natural disaster by decree. Without this publication, the specific guarantee is not activated, even in the event of significant damage.
Once the order has been published, you have a limited period of time to report the claim. A legal franchise applies, the amount of which may increase in municipalities regularly affected.
