Tilbury is a port town on the north bank of the Thames in the borough of Thurrock in Essex, England. The town was established as separate settlement near East and West Tilbury and Tilbury Fort in the late 19th century, on land that was mainly part of the parish of Chadwell St Mary. The Gravesend–Tilbury Ferry was an ancient and important crossing point. Tilbury is part of the Port of London with a major deep-water port which contributes to the local economy. It lies 24 miles (39 km) east of central London and adjoins the town of Grays. It is the southernmost point in Essex. At the 2021 census the Tilbury built up area had a population of 14,185.
Ordnance Survey places 232 postcodes in Tilbury 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 6,163 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 0 | 0 | 0 |
| Medium | 2 | 3 | 3 |
| Low | 8 | 117 | 112 |
| Very low | 222 | 6,043 | 5,270 |
| All bands | 232 | 6,163 | 5,385 |
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 the River Thames (Northfleet Hope) (tidal here), about 250 m from the middle of Tilbury's gauges.
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 the River Thames (Northfleet Hope) nearest the middle of Tilbury'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.
