Known caveats

  • Flood summaries are postcode-geometry signals only and do not replace a property-specific flood assessment.
  • The current public flood seam does not expose a trustworthy row refresh timestamp, so freshness is still partial here.
  • Use the official long-term flood risk service before you rule a postcode in or out on this tool alone.
