Flood risk checker

Search a postcode or postcode area against the current live flood-risk postcode summary seam.

Source: Flood risk postcode summary. Coverage: Live flood summary rows matched postcode GU34 1GY. Treat the result as a postcode geometry signal rather than a property-specific verdict.. Freshness: Row refresh date unavailable in current public seam. Matches: 1.

Postcode	Area	Risk level	Feature summary	Flood zones	Planning note
GU34 1GY	East Hampshire	No direct flood match	No flood feature matches in the current postcode geometry seam.	Zone detail unavailable	Treat this as an early screening signal only and still check the official flood service before you commit.

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.
