Flood risk tools for spatial and property insight
Cotality offers two flood risk solutions that work together - visualising potential flood impact on the map and providing a flood risk score at the property level.

Flood map visualisation
View modelled flood extents by type (river, rainfall, coastal) and return period, giving you a spatial understanding of where flood risk exists and how severe it may be.
Property-level flood scoring
Get a simple, easy-to-understand flood risk score for every address, using the same underlying flood data to support quick assessments and comparisons.
Calculated on position of main dwelling
Cotality addresses are generally positioned on the main dwelling of a property, providing a more accurate assessment of risk.
Flexible access and overlays
Access flood data via API or web platform, and overlay it with your own datasets for richer, contextual insights that support tailored analysis.
