Ordnance Survey places 94 postcodes in Cockermouth 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 1,204 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 33 | 215 | 162 |
| Medium | 42 | 568 | 377 |

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.

Two mapped watercourses are about the same distance from the middle of Cockermouth's gauges: the River Cocker (about 700 m) and Tom Rudd Beck (about 730 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 Cockermouth'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.
