Sheffield is a city in South Yorkshire, England, situated 29 miles (47 km) south of Leeds and 32 miles (51 km) east of Manchester. It is the second largest city in Yorkshire and the administrative centre of the larger metropolitan borough of Sheffield, which had an estimated population of 579,517 in 2025.
Ordnance Survey places 805 postcodes in Sheffield 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 17,540 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 282 | 2,361 | 1,763 |
| Medium | 99 | 1,257 | 870 |
| Low | 411 | 13,793 | 10,155 |
| Very low | 13 | 129 | 64 |
| All bands | 805 | 17,540 | 12,852 |
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 705 more at-risk postcodes, listed on the district pages below.

Two mapped watercourses are about the same distance from the middle of Sheffield's gauges: the River Don (about 450 m) and the River Loxley (about 530 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 Sheffield'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.
