Mostly no, but the exceptions are real and some of them are homes. Only a small part of the area sits in the river flood zones. About one postcode in ten rates high risk once rainfall is counted as well. The Kennet and the Dun both run through town. Hungerford's flood risk belongs to particular streets, and a town-wide average won't tell you which ones.
On the Environment Agency's river-and-sea flood map, about 2% of the Hungerford area's postcodes sit in Flood Zone 3, the highest-probability band. Another 1% sit in Flood Zone 2, the medium-probability fringe that lies beyond Zone 3. The two bands don't overlap, so the smaller Zone 2 figure is correct rather than a mistake. Those are river and sea figures only. Any surface-water figure elsewhere on this site uses a different measure, and the two shouldn't be read as the same thing.
Surface water is the flooding the river zones don't see: heavy rain with nowhere to drain, pooling in the dip at the end of a lane. There's no standalone surface-water share for the area. It's folded into the postcode indicators set out below, which is why those run higher than the river zones. Don't take a clean result on the river map as the whole answer.
Looking ahead, the Environment Agency's climate-adjusted flood zone takes in about 4% of the area's postcodes, compared with about 2% in today's Zone 3. That's modelling of how the flood extent could grow, not a forecast for any particular house.
For insurance, the question is always the individual address. A home in the river zones, or one near a watercourse, can expect more questions from insurers and possibly a higher premium or a larger excess. A home up the hill won't. Get an indicative quote before you instruct a solicitor, because the underwriter is the one professional in the transaction with nothing to gain from you completing.
Across the area's postcodes, counting every indicator including surface water, about 11% rate high on at least one measure, about 11% medium and about 21% low. These bands overlap with the river zones above, so they can't be added to them. It's a broader net, catching any postcode that trips a single indicator.
The more useful figure is homes. The Environment Agency's rivers-and-sea mapping lists 1,344 properties in the area's at-risk postcodes: 161 at high risk, 85 at medium and 228 at low. Of those at high risk, 116 are residential. Only postcodes carrying some risk appear in that list, so the total isn't every property in the Hungerford area. It is every property the model has reason to worry about.
On whether anything stands between the water and the house: about 3% of postcodes fall inside the high-probability flood extent with defences left out of the model, and the same 3% with defences included. In this model, the defences don't shrink the high-risk footprint at all. "Defended" only means a defence appears in the model. It says nothing about whether the property stays dry, and no survey should treat it as a guarantee.
The nearest tide gauge in the national record is at Portsmouth. Across its measurements from 1962 to 2023, it recorded sea level rising about 2 millimetres a year. That's a measured historic rate at a coastal gauge, not a forecast, and for an inland river town it's background rather than a warning.
Hungerford's flood risk is middling. Most of the area is dry, but the homes that aren't are counted in their hundreds, and the model's defences do nothing for them. What you pay depends on which street, and on how close the house sits to the river.
- Put the exact address into the Environment Agency's long-term flood-risk service, for both rivers and surface water.
- Get an indicative buildings-insurance quote before you instruct a solicitor.
- Ask the seller directly whether the property has ever flooded or made a flood claim.
- Ask your surveyor to comment on drainage and on how close the property is to the river.
