Mostly no, and then very specifically yes. The river-and-sea flood zones cover only a sliver of the village. Broader indicators, the ones that count rainwater with nowhere to go, flag around one postcode in eight as high risk. Nothing in the historic record has flooded. This is not a floodplain village. It is a dry village with a handful of wet addresses, and which one you buy is the whole question.
On rivers, the Environment Agency's zone mapping puts about 3% of the area's postcodes in flood zone 3, the high-probability band, and about another 3% in flood zone 2. Those two are separate bands rather than one inside the other, so zone 2 is the additional medium-probability fringe sitting beyond zone 3, not a bigger circle drawn around it. Both are small shares. The River Till runs close to its source here, which is a modest amount of water for most of the year and an opinionated amount of it for the rest.
Surface water is the part that actually catches people out, and it does not show up in the zone maps at all. The broader postcode-level indicators fold rainfall runoff in alongside rivers, and they produce a noticeably larger high-risk share than the river zones do. On chalk downland with a valley running through it, water that cannot soak away goes wherever the road camber sends it. The difference between the two measures is not a contradiction. It is the difference between a river breaking its banks and a lane turning into a stream for four hours in February.
Looking forward, the Environment Agency's climate-change allowance raises the zone share to about 8% of postcodes. That is the modelled position under a wetter future rather than today's map, and it is the figure to hold in mind if the plan is to stay for thirty years rather than five.
For insurance, none of this is fatal, but it is not free either. A property sitting in a high-probability extent will attract questions, a higher excess for flood specifically, and in some cases a refusal from the cheapest comparison-site quotes.

At postcode level, on at least one flood measure, around 13% of postcodes here rate high, about 8% medium and about 20% low. Those bands include surface water and overlap with the river zone figures rather than sitting alongside them, so they should never be stacked together into a bigger total. Around 20% at low risk is doing something useful: it means a fifth of the place carries a rating that is not nothing.
The count of homes is the more concrete version. Across the 47 postcodes that carry any river or sea risk at all, the Environment Agency's mapping covers 1,154 properties, of which 86 sit at high risk, 34 at medium and 108 at low. Seventy of the high-risk properties are residential. Postcodes with no risk do not appear in that list, so this is the affected slice rather than the village.
On defences, about 4% of the area's postcodes fall inside a high-probability extent where the model includes no defence, and about 4% inside one where a defence is present. The word "defended" is doing less work than it sounds like it is. It means a structure exists in the model. It does not mean the water has been beaten, and no surveyor will tell you otherwise.
The nearest tide gauge is at Portsmouth, where the record from 1962 to 2023 shows sea level rising by roughly 2 millimetres a year. That is a measured historic rate rather than a projection, and for a village this far inland on Salisbury Plain it is context rather than a threat.
There is no recorded historic flooding in the area at all. That is genuinely reassuring and it is also not a guarantee, because a record only holds what somebody wrote down.
Flood risk here sits in the middle: not a place with a flooding problem, but a place with flooding postcodes. Get the address checked on the Environment Agency's own long-term risk tool before you fall in love with the garden.
