Flood risk lookup FAQ
How do I check flood risk for a UK postcode?
Enter the full postcode and choose a search radius. We geocode the location, then query the Environment Agency flood-monitoring API for nearby flood warning areas and any active warnings or alerts.
Is this the same as Flood Map for Planning?
No. Blue overlays here are live flood warning areas from the Environment Agency monitoring service, not the static Flood Map for Planning zones used in planning applications.
Why check flood risk before buying a property?
Flooding can damage property, raise insurance costs and affect mortgageability. A postcode flood lookup highlights nearby warning areas so you can dig deeper before you buy.
What does an all-clear status mean?
Clear means no active Environment Agency flood warning or alert was returned within your radius at check time. It does not guarantee the property will never flood — review long-term risk and insurer advice separately.
Data from the Environment Agency flood-monitoring API and OpenStreetMap. Live warnings change quickly — always confirm on GOV.UK check for flooding for official advice.
