Up to Low likelihood
Properties in SR2 7HH sit in the Environment Agency's Low flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
| Likelihood band | Annual chance | Properties | Of which homes |
|---|---|---|---|
| High | greater than 3.3% | 0 | 0 |
| Medium | 1% – 3.3% | 0 | 0 |
| Low | 0.1% – 1% | 1 | 0 |
| Very low | below 0.1% | 0 | 0 |
Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.
SR2 7HH gets about 661 mm of rain a year on average (wettest month November, 74 mm; driest March, 40 mm). That is 43% drier than the UK as a whole, which averages 1,163 mm a year.
A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.

The ground here sits at about 41 m above sea level and falls 24 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south, 4.2 m higher.
The river map has no watercourse within 1 km of the centre of SR2 7HH.
That means this spot is not on the river map, not that there is no water here: Ordnance Survey’s river map (OS Open Rivers) leaves out small streams, ditches and culverts. Contains OS data © Crown copyright and database rights 2026.
Because properties in the low likelihood band; 310 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around SR2 7HH. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
None mapped within ~1 km of this postcode's centre.
No recorded outline near this postcode means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. The full report tests every other flood source at the exact building.
