Environment Agency Flood Datasets
Below is a more-or-less comprehensive list of Environment Agency flood-related datasets that are available for re-use (mostly on commercial terms).
Where available I have included links to extracts from the EA's Information for Re-use Register and to the corresponding layers on the EA's Interactive Maps site.
Datasets marked with * have been temporarily released as open data, in whole or part, for three months ending 15/05/2014.
