Yes, and the river flood zones make Staplehurst look drier than it is. Hardly any postcodes fall in the official river-and-sea flood zones. Once surface water is counted, about a third of postcodes are rated high. The river has flooded the village before. Look at the maps you'd normally skip before you look at the kitchen.
On the Environment Agency's river-and-sea mapping, about 2% of Staplehurst's postcodes are in Flood Zone 3, the highest-probability band, and none are in Flood Zone 2, the medium-probability band just outside it. The river risk is real but limited to a small part of the village. The Environment Agency has four recorded flood events here. The most recent was in December 2013, when a main river rose higher than its channel could hold and there were no raised defences to stop it.
The river-and-sea zones leave out surface water, which is what happens when heavy rain can't drain away fast enough. That's the risk that catches out buyers in places like Staplehurst, because it doesn't need a river nearby. It isn't shown on the zone map, so a home can sit well outside every flood zone and still be exposed. The postcode figures further down include it. About 2% of postcodes also sit within the Upper Medway Internal Drainage Board's area, where the drainage of low-lying land is actively managed.
The Environment Agency's climate-adjusted mapping widens the river-and-sea flood zones to about 3% of postcodes. That's a forward-looking model of what wetter decades could do. It isn't a forecast for any particular street, but it shows which way the flood lines are expected to move.
For insurance, the postcode matters more than the viewing. A home carrying a high flood flag can mean higher premiums, a larger excess, or insurers declining to quote at all. Buyers who get a quote after exchanging contracts sometimes find the house was cheap for a reason. Get an indicative quote on the exact address before you instruct a solicitor, and ask the seller directly whether the property has ever flooded or made a flood claim.
At postcode level, and counting any of the flood measures including surface water, about 33% of Staplehurst's postcodes are at high risk on at least one measure, 30% at medium risk and 47% at low risk. These shares overlap, because a postcode can carry several flags at once. They also can't be added to the flood-zone figures above. They're a broader measure, which is why they come out so much higher.
Counting homes rather than postcodes, the Environment Agency's river-and-sea risk data lists 144 properties across the postcodes that carry any risk. Of those, 27 are at high risk, 9 at medium, 17 at low and 8 at very low, and 13 of the high-risk properties are homes. Postcodes with no river or sea risk don't appear in these counts. A small number of properties, then, but for those owners the risk is concrete.
On whether anything stands between the water and the high-risk homes: about 2% of postcodes fall inside the high-risk flood extent without defences in the model, and the figure stays at about 2% with defences included. The defences make no difference to the high-risk count. Even where a defence does appear in the model, that only means it exists. It doesn't mean the house behind it is safe.
The nearest tide gauge, at Dover, recorded sea levels rising by about 2 millimetres a year over its record from 1961 to 2010. That's a measured historical rate at the coast, not a prediction for an inland village. The water most likely to reach a Staplehurst home comes from the sky and the river, not the sea.
Flooding is Staplehurst's weakest point. The river risk is small, but the surface-water exposure is broad enough that every buyer should treat it as a question to answer before making an offer.
