Mostly no, and where it is yes the culprit is rain rather than the river. The Stour runs straight through the middle of the place and virtually nothing sits in the river-and-sea flood zones. What risk registers comes from surface water, scattered thinly across the postcodes. Nothing has ever been recorded as flooding here. For a town wrapped around a meander that is a better position than it has any right to expect, and it is not luck.
On the Environment Agency's river-and-sea mapping, about 1% of the area's postcodes fall inside flood zone 2 and none at all fall inside zone 3. Those are separate bands rather than nested ones: zone 3 is the higher-probability core and zone 2 the medium-probability fringe beyond it, so an empty zone 3 sitting alongside a thin zone 2 is exactly the profile of a settlement that stayed off its own floodplain. The old town went up on the limestone ridge above the water, and when the ford was replaced in the sixteenth century the crossing was carried over the meadow on an embankment. Nobody here has ever tried to argue with the river.
Surface water is the risk the river zones do not catch, and here it is what the numbers are really measuring. It is folded into the postcode-level indicators rather than mapped as its own line, and it is the reason this place records any flood risk at all rather than a clean sheet.
Adding the climate allowance shifts almost nothing. About 1% of postcodes sit inside the climate-adjusted zone, the same share as the present-day zone 2.
For insurance this is the straightforward end of the market, but cover is priced off an address and not off a town name. Get an indicative quote before instructing a solicitor, and ask the insurer specifically about surface water, since that is where any loading in a place like this would come from rather than from the Stour.
Across the 128 postcodes assessed, about 7% rate high on at least one flood measure, about 8% medium and about 31% low. At least one measure means rivers, sea or surface water, so those bands overlap the zone figures rather than stacking on top of them. Anyone adding the two sets together is inventing a problem.
Counting homes rather than postcodes lands differently. The Environment Agency's rivers-and-sea mapping lists 3 postcodes here as carrying any risk at all, covering 97 properties between them: 1 at high risk, none at medium and 2 at low. None of the high-risk properties is residential. Only postcodes with some risk appear in that mapping at all, so the absence of everywhere else from the list is the substance of the answer.
On the modelled flood extents across 133 postcodes, no postcode sits inside a high-risk extent, whether undefended or behind a defence, and about 1% sits in a low-risk undefended extent. Defended in that modelling means a defence is present, not that a building is safe, and it should never be read as a guarantee. Here the distinction barely gets to do any work, because there is almost nothing inside the extents in the first place.
The nearest tide gauge with a long record is at Portsmouth, where sea level rose by about 2 millimetres a year across the 1962 to 2023 record. That is a measured historic rate on the coast rather than a projection, and for a town this far up the Stour it is background rather than a warning.
No historic flooding is recorded for the area. That is worth having, because recorded events are what searches and insurers pick up. It is not the same as proof that water has never come up the meadow, only that nobody wrote it down.
Flood risk here comes out middling rather than clean: near enough nothing from the river, a scatter of postcodes flagged on surface water, and an empty history. Check the specific address rather than the town, because in a place with these numbers the gap between the two is the entire answer.
