Flood risk API

Generate comprehensive assessments of current & future flood risk at UK properties or locations.

Access risk assessments alongside complimentary data including historical flood events and reliance on flood defences.

The PropEco Flood Risk API provides data & analysis relating to the flood risk at UK properties and locations. Each assessment includes:

Flood risk

Risk of flooding from rivers, seas and surface water.

Flood risk with climate change

Risk of flooding across future climate change scenarios.

Elevation

Height above sea level of the property or location.

Historical flooding

Details of recorded flood events.

Flood defences

A check to determine whether the property or location benefits from flood defences.

Access hundreds of data points with just four lines of code and a coordinate.
