Yes, and not from a river. Almost nothing here sits inside the river flood zones. About a fifth of postcodes still rate high on at least one flood measure. What makes the difference is surface water, which is rain arriving faster than the ground and the drains can take it away. This is the sort of flooding that never gets a swollen river on the regional news and still ruins a ground floor.
Start with the mapping most buyers have heard of. On the Environment Agency's river-and-sea flood zones, 1% of the area's postcodes fall inside zone 3, the highest-probability band, and a further 1% inside zone 2, which is the medium-probability fringe lying beyond zone 3 rather than a larger area containing it. Those are small numbers and they are honest ones. If your only question is whether a watercourse is going to come over its banks into the village, the answer is that it is a minority concern affecting a handful of properties.
The problem is that river-and-sea mapping is not the measure that matters most here. On the postcode-level indicators, which fold surface water in alongside rivers and sea, 21% of Tatworth postcodes carry a high rating. Surface water is a function of topography, hard standing and drainage capacity rather than proximity to a channel, which is why a house can sit nowhere near a stream and still take water through the back door after an hour of the wrong kind of rain. Somerset villages surrounded by farmland are exactly the geography where this happens.
Looking forward, the climate-adjusted extent brings 4% of postcodes inside the modelled flood zone. That is a modelling allowance rather than a prediction of any particular year, and it is the figure a lender or an insurer is increasingly likely to be looking at over the life of a mortgage.
For insurance, this is not a village where cover is unobtainable, but it is a village where the specific address matters more than the postcode. Get an indicative quote before instructing a solicitor, ask the seller directly what they currently pay and whether they have claimed, and put the exact address into the Environment Agency's long-term flood risk service rather than relying on any village-level summary, including this one. Two houses on the same lane can sit either side of a contour and price completely differently.
The full postcode picture reads as 21% high, 17% medium and 44% low, each of those being a rating on at least one flood measure. Those bands overlap with the river-and-sea zone figures above rather than adding to them, so a postcode counted in the high band may be there because of surface water alone. It is one property's risk described three different ways, not three separate risks stacked on top of each other.
Counted as homes rather than postcodes, the Environment Agency's rivers-and-sea mapping covers 122 properties across the six Tatworth postcodes that carry any risk at all. Of those, 30 are at high risk, three at medium and 13 at low. Twenty of the high-risk properties are residential. Postcodes with no modelled risk do not appear in that list at all, which is why the count is small against the size of the village.
On defences, 1% of postcodes sit inside the modelled high-risk extent with a defence present, and another 1% inside the high-risk extent with no defence in the model. A defence appearing in the model means a structure exists, not that the house behind it stays dry. Defences are designed to a standard and water occasionally declines to read the specification.
Sea level is context rather than threat here. The nearest tide gauge is at Devonport, where the record from 1962 to 2015 measured a rise of about 2.35 millimetres a year. That is a measured historic rate at the coast, and the mechanism that would put water in a Tatworth kitchen is rainfall, not tide.
There is no recorded historic flooding across the area in the mapping, which is genuinely worth something. It is not the same as proof that no house here has ever flooded, because records are patchy and small events go unrecorded, but nothing in the history is flagging a repeat problem.
Flooding is the weakest thing about Tatworth. The river risk is negligible and the surface-water risk is not, so the answer for any individual house sits somewhere between a non-issue and a serious one, and nothing short of an address-level check will tell you which.
