Flood Risk
Property-level flood risk from rivers, the sea, and surface water — sourced from DEFRA's NAFRA2 national dataset. A single API call returns the risk level for any of 29 million UK properties, with no GIS expertise required.
Risk profile at a glance
Each property returns up to two flood risk scores — rivers & sea, and surface water — both from point queries at the property location.
Response fields
Returned for each flood risk sub-type in the results[] array.
Built for
Mortgage lenders
Flag high-risk properties at application stage. Surface water risk is increasingly material for mortgage decisions — get both scores in one call.
Conveyancing tools
Add flood risk to property reports automatically. Required disclosure for buyers — previously needed a £30+ specialist search per property.
Insurance underwriting
Pre-underwrite portfolios at scale. Screen thousands of addresses in minutes to identify high-risk clusters before pricing.
