Methodology
The position of the postcode is determined using a point location from Open Postcode Geo. This point location places the postcode in the corresponding area within Risk of Flooding from Rivers and Sea and the risk level (PROB_4BAND) is linked to the postcode. This allows flood risk level to be looked up by postcode.
Note that properties within the postcode may have a slightly different point location and thus be located in a different area with a different risk level. Generally speaking the point location of the postcode is determined by the point location of the centremost property in that postcode.
