Up to Medium likelihood
Properties in PL26 7AR sit in the Environment Agency's Medium 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% | 19 | 15 |
| Low | 0.1% – 1% | 0 | 0 |
| Very low | below 0.1% | 4 | 2 |
Over a 25-year mortgage, a property in a medium-likelihood area has a 22–57% chance of flooding at least once.
PL26 7AR gets about 1,278 mm of rain a year on average (wettest month November, 160 mm; driest June, 70 mm). That is close to 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 29 m above sea level and falls 86 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-west, 60.6 m higher.

The map above shows the real EA rivers & sea likelihood cells around PL26 7AR. 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 |
|---|---|---|
| Oct 2011 | CW8963 - London Apprentice | ~0.3 km |
| Nov 1997 | CW8382 - Pentewan | ~1.5 km |
| Nov 1997 | CW8189 - London Apprentice | ~0.5 km |
| Oct 1988 | CW8839 - Little Polgooth | ~0.4 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.
