For most homes in Liphook, flood risk from rivers is very low, and surface water is the risk worth checking. Hardly any of the village sits in the river flood zones. None of it is in the highest-risk zone. A minority of postcodes carry a surface-water flag. The flood-zone map clears most of Liphook, and the checking starts at the postcode level.
The village grew on higher ground above the marshes around the River Wey, and the Environment Agency's mapping still reflects that. Under 1% of Liphook's postcodes sit in Flood Zone 2, the medium-probability band for river and sea flooding. None sit in Flood Zone 3, the highest-probability band. The two zones don't overlap: Zone 2 is the outer band beyond Zone 3, not a larger area that includes it. On the Environment Agency's property-level register of river and sea risk, only one postcode in the village is listed at all, covering six properties, and none of them is rated high or medium.
Surface water is a separate question and needs a separate check. It happens when heavy rain can't drain away fast enough, and it doesn't need a river nearby. Because almost nothing in Liphook falls in the river zones, most of the flood flags described below are likely to come from surface water. The river-zone map won't show them. The Environment Agency's surface-water map, searched by your own address, will.
Looking ahead, the Environment Agency's climate-adjusted flood zone still covers under 1% of Liphook's postcodes. On river and sea flooding, the forward view looks much the same as the current one.
For insurance, what counts is the individual property's risk, not the village's. A home outside the river zones with no surface-water flag should be straightforward to insure. A home on one of the flagged postcodes may attract more questions, a higher premium or an excess, even though it is nowhere near a river.

Looking at each postcode across every flood indicator, including surface water, about 8% of Liphook's postcodes rate high on at least one measure, about 14% medium and about 21% low. These bands overlap with the flood-zone figures above and include them. They aren't extra postcodes to add on top. Most of Liphook still carries no flag at all. That's the figure to check against the postcode of the house you're viewing.
On flood defences, nothing needs defending at the high-risk end. In the Environment Agency's modelled flood extents, none of Liphook's postcodes fall in the high-probability extent, with or without defences. About 1% fall in the low-probability extent with no defence modelled. Even where the model does show a defence, that only means a defence exists on the map. It doesn't mean the house behind it is safe.
Sea level is a distant concern for an inland village, but the record exists. The nearest tide gauge, at Portsmouth, recorded a rise of about 2 millimetres a year between 1962 and 2023. That's a measured historical rate over that period, not a forecast. It matters more to the coast than to Liphook.
There's no recorded flooding in Liphook in the historic flood records. That's reassuring, though it doesn't prove the village has never flooded. Small surface-water incidents on a single street often go unrecorded.
Liphook's flood risk is middling overall and low from rivers. The surface-water flags on a minority of postcodes are what stop it being better, so check the address, not the village.
