FloodScore Postcode uses the most complete and up-to-date flood risk data available to quantify the likelihood of flooding to a postcode area due to rainfall, overflowing rivers, tidal surges or groundwater. It classifies the flood risk as being Negligible, Minimal, Moderate, High or Extreme. The results for each postcode include a range of statistics from the average risk to the maximum risk.

FloodScore Postcode is available as a complete database. It is most often delivered as a CSV or SQL file and can be licensed on varying terms, either as a standalone product or alongside our FloodScore Property data.

The database is available on either single or multi-year licence agreements, or as a one-off dataset.
