No, not in the way the word usually means. Delabole sits outside the river and sea flood zones altogether, and no flooding has ever been recorded here. What the mapping does flag is rain, with roughly one postcode in nine carrying a high rating on at least one indicator. There is no river to burst and no sea to come over a wall. There is only what falls on the village and where it goes after that.
On the Environment Agency's river-and-sea flood zones, the figure is zero in both directions. None of the area's postcodes sit in flood zone 3, the higher-probability band, and none sit in flood zone 2, the medium-probability fringe that sits beyond it. Those two zones are separate bands rather than one inside the other, which is why a place can score zero on both and mean it. For a buyer, that is the cleanest possible answer to the question a conveyancer will ask.
Surface water is the risk that actually applies here, and it is measured on a different footing entirely. With the river and sea zones empty, anything the indicators pick up is coming from rainfall, drainage and run-off rather than a watercourse. That is a highway and gutter problem, not a floodplain problem, and it behaves accordingly: local, sudden, and specific to a dip in a lane.
The climate-adjusted picture does not change the answer. The share of the area falling into the flood zones once a climate allowance is applied is still zero, which means the forward look here is the same as the present one.
For insurance, that combination should keep cover straightforward and pricing unremarkable. Insurers rate the individual address rather than the village, though, and a postcode carrying a surface-water flag can still surface in a quote even where the zones are clear. An indicative quote before instructing a solicitor costs nothing and settles it.
Taking every source together, across the 55 postcodes in the area, about 11% carry a high rating on at least one flood indicator, about 13% a medium one, and about 31% a low one. Those bands fold surface water in alongside rivers and the sea, so they overlap with the zone figures rather than adding to them. The two measures answer different questions and should never be stacked.
On the modelled flood extents, nothing sits inside a high-risk area at all, defended or undefended, both figures being zero. The distinction matters elsewhere and is worth understanding: a property marked defended only means the model knows a defence exists nearby, not that the house behind it is safe. Here the question simply does not arise, because there is no extent to be inside.
The shoreline is a separate matter. Every postcode in the area falls within a shoreline management plan, and the stated policy across the twenty, fifty and hundred year horizons is no active intervention. That is the official phrase for nobody is coming. It is a statement of intent rather than a promise, and it describes a coastline rather than a village, with the nearest sea about 2.2 kilometres away and the typical postcode closer to 2.9 kilometres from it. The practical exposure is to the cliff path and the beach at Trebarwith Strand, not to anyone's living room.
At the nearest tide gauge, at Devonport, sea level rose at about 2.35 millimetres a year across the record from 1962 to 2015. That is a measured historic rate rather than a projection, and it is the number worth holding on to when coastal change comes up.
No historic flooding is recorded in the area, which is genuinely reassuring rather than a technicality. It is not the same as proof that water has never come through a door here, because records begin when someone starts keeping them, but nothing on the register suggests it has.
Flood risk in Delabole lands somewhere in the middle: no floodplain, no coastal exposure, no history, and a rainfall flag on a minority of postcodes that a specific address check will either confirm or dismiss in an afternoon.
