Filton has no mapped rivers-and-sea flood risk: neither the national risk assessment nor the planning Flood Zone map covers it. That is not a statement that Filton cannot flood — this figure covers rivers and the sea only, and surface water flooding is not included. The nearest gauge is 1.2 km away.

Filton has 11,444 residents and 5,098 homes. Ranked equal 3078 of 7,114 — the places where the national risk assessment maps no rivers-and-sea exposure for any home, so the position is a tie rather than a low score.

What Does Filton's Flood Risk Classification Mean?

0% of postcodes in Filton sit in Flood Zone 3, the planning band for land with a 1% or greater annual chance of river flooding or 0.5% or greater of sea flooding — and the map that draws it deliberately ignores flood defences.

The flood risk band for rivers and the sea is not mapped here, which means the national assessment finds no rivers-and-sea exposure for Filton's homes rather than a low amount of it. That is a statement about rivers and the sea only: surface water flooding is not included, and it is the larger source nationally.

Which Postcode Districts Cover Filton?

Each district below is one postcode district that falls inside Filton. The band is the one shared by most of that district's postcodes, so it describes the district rather than a single street — enter a full postcode in the checker for one address. A district can cover more than one town: every district here overlaps another place, so the checker may name a neighbouring town for some of these postcodes.
