Flooding probability from surface water % in lending decisions.
Flooding probability from surface water % gives the annual probability of surface-water flooding at the address, a percentage distinct from the category field, published modelled with 98.45% coverage across England. Where modelled, it remains separate from declared evidence so you can validate it against your own reference records. Attribution and refresh period are in the dictionary.
Pretira publishes flooding probability from surface water % modelled at 98.45% coverage across England, refreshed yearly, with declared and modelled kept separate.
