Hazel Grove is a village in the Metropolitan Borough of Stockport, Greater Manchester, England. It lies within the historic county boundaries of Cheshire and became part of Greater Manchester in 1974. The built-up area, as defined by the Office for National Statistics, had a population of 20,170 at the 2021 census.
Ordnance Survey places 24 postcodes in Hazel Grove 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 316 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 9 | 61 | 57 |
| Medium | 6 | 126 | 125 |
| Low | 7 | 70 | 55 |
| Very low | 2 | 59 | 57 |
| All bands | 24 | 316 | 294 |
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 Poise Brook, about 10 m from the middle of Hazel Grove's gauges. It flows into the River Goyt about 2.9 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 Poise Brook nearest the middle of Hazel Grove'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.
