Barely, and not in any way the official mapping recognises. None of the village sits in a river or sea flood zone. Nothing here carries a recorded history of flooding. The only water risk that shows up at all is rain landing on ground that has to do something with it, and it touches a small handful of postcodes. If flooding is the thing keeping you awake about a move, this is one of the few places where you can put it down.
On rivers and the sea, the Environment Agency's mapping puts 0 percent of the area's postcodes in flood zone 3 and 0 percent in flood zone 2. Those two are separate bands rather than one inside the other, with zone 2 covering the additional medium-probability fringe that sits beyond zone 3, so a place can legitimately hold a bit of one without the other. Redlynch holds none of either. The rivers that matter to this part of Wiltshire run their flood plains somewhere other than under these houses.
Surface water is the mechanism worth thinking about instead, because it reaches places rivers never do. It is not mapped here as its own separate share; it sits folded into the combined postcode indicator further down. Surface-water flooding is about how much rain arrives at once and where the ground sends it afterwards, which in practice means lanes, dips, drives that slope the wrong way, and the bottom of somebody's garden. It is also the type most likely to surprise a buyer who checked the flood zone, saw nothing, and stopped looking.
The forward look does not change the picture. Under the climate-adjusted flood zone, which builds in an allowance for future conditions rather than describing today, the share of the area's postcodes affected is still 0 percent.
For insurance, that combination is about as straightforward as it gets. Cover should be ordinary rather than a negotiation, and there is no reason to expect a flood exclusion or a loaded premium as a matter of course. Insurers price the individual address rather than the village, so a specific property at the low point of a lane can still be treated differently from its neighbour up the hill. Get an indicative quote before you instruct anyone, because that is the fastest honest answer about a particular house.
Across the 82 postcodes assessed here, about 2 percent rate high on at least one flood measure, roughly 1 percent rate medium, and around 11 percent rate low. That is a broader indicator than the flood zones above, folding surface water in alongside rivers and sea, so the two sets overlap and cannot be stacked on top of each other. The high-rating share is small enough to be a matter of specific addresses rather than a characteristic of the village.
On the modelled flood extents, 0 percent of postcodes here fall inside a high-risk extent whether a defence is present or not. That is the cleaner version of the answer: nothing in Redlynch is relying on a wall, an embankment or a pumping station to stay dry. Worth knowing generally, because a property described as defended is one where a defence exists in the model, which is a different claim from the property being safe.
The nearest tide gauge is at Portsmouth, where the record from 1962 to 2023 shows a measured rise of about 2 millimetres a year. That is history rather than forecast, and the distance to that gauge tells you roughly how much the sea features in a decision about this village.
No historic flooding is recorded across the area at all. That is genuinely reassuring, with the caveat that a clean record means nothing was recorded rather than proving nothing ever happened.
Flooding is one of the easier boxes to tick here, and the only sensible caution is to check the individual house rather than the village, since a small number of addresses carry a high rating on the wider measure.
