Ordnance Survey places 29 postcodes in Mangotsfield in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea).

This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.
