Check your flood risk on a map (Flood Risk Assessment Wales Map)
Check if you're at risk
The Flood Risk Assessment Wales map shows your risk of flooding from:
surface water and small watercourses
The map also provides additional information about your area, such as:
the location of flood defences
the areas benefitting from flood defences
You can also see all the areas we cover for free flood warnings and alerts.
(Right click on the map button to open it in a new tab)
You can also check your flood risk by postcode.
The Flood Risk Assessment Wales map has no official status for planning purposes. You should not use it to inform Flood Consequences Assessment to support planning proposals. Use the Flood Map for Planning / Development Advice Map for development planning. Together, these two maps form the Wales Flood Map.
