No property in an EA risk band
No property in TN15 0HP 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 TN15 or get the full picture below.
TN15 0HP gets about 749 mm of rain a year on average (wettest month October, 84 mm; driest July, 46 mm). That is 36% 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 127 m above sea level and falls 39 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south-east, 3.3 m higher.
The river map has no watercourse within 1 km of the centre of TN15 0HP.
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 2 recorded flood outlines mapped nearby; 62 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around TN15 0HP. 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 | 07302C200_Dec2013_Medway_Eden_Teise_Beult | ~16.0 km |
| Sep 1968 | 07337E200_SEPT1968_Darent_Sevenoaks_Greatness | ~1.4 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.
