Kingston upon Thames, colloquially known as Kingston, is a town in the Royal Borough of Kingston upon Thames, south-west London, England. It is situated on the River Thames, 10 miles (16 km) south-west of Charing Cross. It is an ancient market town, notable as the place where some Saxon kings were crowned.
Ordnance Survey places 318 postcodes in Kingston upon Thames 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 6,917 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 72 | 1,086 | 995 |
| Medium | 114 | 2,635 | 2,348 |
| Low | 132 | 3,187 | 2,534 |
| Very low | 0 | 9 | 2 |
| All bands | 318 | 6,917 | 5,879 |
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.
…and 218 more at-risk postcodes, listed on the district pages below.

Two mapped watercourses are about the same distance from the middle of Kingston Upon Thames's gauges: the Creek (Hogsmill River) (about 200 m) and the River Thames (about 240 m), so this page cannot say which one is nearer to you.
Distances along the river are from the point on each watercourse nearest the middle of Kingston Upon Thames'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.
