Hedge End is a town and civil parish in Hampshire, England. Situated to the east of the City of Southampton, it adjoins the districts of West End and Botley. Hedge End lies within the Borough of Eastleigh and is part of the Southampton Urban Area. The original hamlet developed on Botley Common after 1250 when it was granted to the men of Botley as common pasture. In 1267, royal charters allowed Botley to hold an annual fair and a weekly market on the common which eventually became a market town.
Ordnance Survey places 26 postcodes in Hedge End in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 117 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 11 | 30 | 25 |
| Medium | 5 | 24 | 18 |
| Low | 10 | 63 | 58 |
| Very low | 0 | 0 | 0 |
| All bands | 26 | 117 | 101 |
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.

The nearest watercourse on the river map is an unnamed stream, about 110 m from the middle of Hedge End's gauges. It flows into Pudbrook Lake about 1.1 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on an unnamed stream nearest the middle of Hedge End's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
