Yes, and the risk is high. About a quarter of the village's postcodes sit in the highest-risk river flood zone. Four in ten rate high on at least one flood measure. The rivers here have dozens of recorded floods behind them. In Yalding, the flood search is the first document to read, before the survey.
On the Environment Agency's river-and-sea mapping, about 27% of Yalding's postcodes fall in Flood Zone 3, the highest-probability band, and a further 2% in Flood Zone 2, the medium-probability fringe beyond it. The two bands don't overlap. Almost all of the exposure sits in the top band, with very little middle ground. The agency holds 52 recorded flood events for the area, the most recent in December 2013, when a main river exceeded its channel where no raised defences stood. About 27% of postcodes sit within a historic flood outline.
There is no separate published surface-water share for Yalding. Surface water is folded into the postcode-level measures below, so no separate surface-water figure appears here.
With the climate allowance applied, the share of postcodes in the modelled flood zone is about 28%. That is the Environment Agency's forward look at the same rivers. It is a modelled extent, not a prediction of when the next flood will come.
Insurance is where a buyer feels this first. Homes in the highest flood zone, or with a recorded flood on the address, can face higher premiums, larger excesses or fewer insurers willing to quote. Get a real quote for the exact address before you instruct a solicitor, because a listing's "riverside" becomes a line on the premium.
At postcode level, about 41% of Yalding's postcodes rate high on at least one flood measure, about 22% medium and about 30% low. These bands fold surface water in with rivers and sea, and they overlap with the zone figures above, so the two sets can't be added together. They measure the same village in two different ways.
Counting homes rather than postcodes gives a more useful figure. The Environment Agency's rivers-and-sea mapping lists 24 postcodes in Yalding that carry some risk, covering 365 properties. Of those, 161 are at high risk, 96 at medium, 18 at low and none at very low. Of the high-risk properties, 125 are homes. Postcodes with no river or sea risk don't appear in the count.
The mapping also answers whether anything stands between the water and the house. About 27% of postcodes sit inside the high-risk extent with defences left out of the model, and the figure is the same 27% with defences included. Defences in the model make no difference to the share at risk. "Defended" only means a defence appears in the model. It says nothing about whether a given home stays dry.
Yalding lies about 9 kilometres from the coast at the median postcode, and every postcode falls under a shoreline management plan. The policy for the next 20 years is to hold the line, which means maintaining the existing defences. For the 50-year and 100-year horizons it switches to managed realignment, which means letting the shoreline move in a planned way. Either policy is a stated intention, not a guarantee and not a defence that already exists.
The nearest tide gauge, at Dover, recorded sea levels rising by about 2 millimetres a year between 1961 and 2010. That is a measured past rate, not a forecast.
Flood risk is Yalding's weakest point, and it is serious. Buy here only once the flood searches, insurance quote and property-level mapping for your exact address all say you can live with the answer.
