No property in an EA risk band
No property in IP24 1HT appears in the Environment Agency's rivers-and-sea flood-risk dataset. That dataset covers one of five flood sources. It is area-level, it covers rivers and the sea only, and it is never proof a place cannot flood — surface water, groundwater, sewers and reservoirs are assessed separately. See the at-risk postcodes in IP24 or get the full picture below.
IP24 1HT gets about 664 mm of rain a year on average (wettest month August, 66 mm; driest April, 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 river map has no watercourse within 1 km of the centre of IP24 1HT.
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 3 recorded flood outlines mapped nearby; 6 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around IP24 1HT. 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.
| Date | Mapped flood extent | Approx. distance |
|---|---|---|
| Dec 2013 | 2013 Flood Outline | ~40.2 km |
| Jan 1968 | 1968 September Flood Outline | ~40.3 km |
| Jan 1947 | March 1947 | ~3.1 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
