Fleet is a town and civil parish in the Hart District of Hampshire, England, centred 38 miles (61 km) south-west of London and 13 miles (21 km) east of Basingstoke, near the towns of Farnborough, Aldershot and Farnham. The town is sometimes referred to as Fleet and Crookham, as the urban development is continuous and inseparable between Fleet, Church Crookham and Crookham Village, while the civil parish of Fleet Town Council manages Fleet town centre and its surrounding areas.
Ordnance Survey places 77 postcodes in Fleet 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 445 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 30 | 114 | 107 |
| Medium | 17 | 75 | 68 |
| Low | 30 | 256 | 242 |
| Very low | 0 | 0 | 0 |
| All bands | 77 | 445 | 417 |
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 Fleet Brook, about 10 m from the middle of Fleet's gauges. It flows into the River Hart about 6.3 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 Fleet Brook nearest the middle of Fleet'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.

No recorded flood outline is mapped around the Fleet town centre means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. FloodRadar has separately logged 10 flood warnings or alerts for the Hampshire area since February 2026. See the flood history link below.
