Germany
Moderate combined riskNew national heat record of 41.8°C set in June 2026; heat-related deaths this year already exceed any full year since 2016.
For every €100 of economic output, the state already owes €64 — and most homeowners would pay storm and flood damage out of pocket.
System: Voluntary, no mandatory system (41% of homes lack natural-hazard cover)
Trend: Mandatory insurance included in coalition agreement, design still open
France
Moderate combined risk2026 heatwaves are projected to cut French GDP growth by roughly a third of a percentage point this year.
France insures nearly everyone against disasters, but is raising the price of that safety net as claims climb.
System: CatNat, mandatory, 98% coverage
Trend: Surcharge raised 12%→20% as of Jan 2025, fiscal strain per Court of Auditors
Italy
High combined riskJanuary 2026 storm 'Harry' caused over €500m in damage across Sicily, Calabria and Sardinia alone.
Debt is the highest of the four, and four out of five euros in flood or storm damage go uninsured.
System: Voluntary, no mandatory system
Trend: Highest gap of the four countries
United Kingdom
Lower combined riskOver 6 million English homes already sit in areas at flood risk; that figure is projected to reach 8 million by 2050.
Debt sits close to one year of national output; flood cover exists, but only for a small, subsidised slice of homes.
System: Flood Re, hybrid, flood cover only
Trend: Scheduled to end in 2039, gap could widen afterwards
No European system has yet solved this trade-off: France covers almost everyone but at rising cost to taxpayers; the UK covers a narrow slice cheaply, with an expiry date; Germany and Italy leave the bill largely to households. As storms and heatwaves become more frequent, the choice for every country is the same — pay for prevention and shared insurance now, or pay for recovery later, and less fairly.
