Partly, and where it applies it applies hard. Most of the town sits outside the river and sea flood zones. A defined slice does not, and that slice is exactly where the harbour, the old streets and the photographs are. Nothing on record says the town has ever flooded. The water is still closer here than almost anywhere else you will look.
The Environment Agency's mapping puts about 9% of postcodes inside flood zone 3, the highest probability band for rivers and the sea, with a further 1% in zone 2, the medium probability fringe that lies beyond zone 3 rather than wrapping around it in the way most people assume. Nine per cent is not most of a town. It is also not nothing, and it is not scattered at random: the zone follows the water, and so does the property everybody wants.
Surface water is the one that catches people out in a town built on a slope, because it has nothing to do with a river and everything to do with where rain goes when the drains give up. It carries no separate published share for this area. It is folded into the combined postcode indicators below, which is why a house sitting well clear of flood zone 3 can still come back flagged.
Looking forward, the climate adjusted version of the zone, which builds in an allowance for future sea level and rainfall, covers about 1% of postcodes.
For insurance, the thing to hold on to is that Brixham is not one postcode. Cover, excess and premium are set at address level, so two houses on the same street can be quoted very differently, and a buyer who takes the seller's word that it has never been a problem around here has bought a story rather than a quote. Get an indicative quote before instructing a solicitor, not after the survey comes back.
On the combined postcode indicators, which fold surface water in alongside rivers and the sea, about 14% of postcodes rate high on at least one measure, 13% medium and 28% low. Those bands overlap with the flood zone figures rather than adding to them, and mixing the two is how a town ends up sounding twice as wet as it is.
Counted as homes rather than postcodes, the Environment Agency's rivers and sea mapping lists 2,124 properties across the postcodes carrying any risk at all. Of those, 193 sit at high risk, 213 at medium and 297 at low, with 118 of the high risk ones residential. Only postcodes with some risk appear in that list, so it describes the exposed part of Brixham rather than the whole town.
About 3% of postcodes fall inside a high risk flood extent with no defence present in the model, and about 2% inside one where a defence is present. Present in the model is the precise phrase and it promises nothing. It means something has been built, not that it is high enough, maintained, or designed for the storm that eventually turns up.
Proximity is the defining fact. About 42% of postcodes sit within 500 metres of the coast, that being the threshold the data draws rather than a statement about any single address, and the median postcode is around 630 metres from the water. The closest is about 16 metres.
Every postcode here falls under a shoreline management plan, and the stated policy over the 20, 50 and 100 year horizons is hold the line, meaning the intention is to maintain the coastal defence line where it currently runs. An intention is not a defence, and it is not a guarantee that the funding arrives in year 40.
At the nearest tide gauge, at Devonport, sea level rose about 2.35 millimetres a year across the record from 1962 to 2015. That is a measurement of what has already happened rather than a forecast of what comes next.
No historic flooding is recorded for the area at all. That is genuinely reassuring, and it is worth being precise about what it means: nothing has been logged in the dataset, which is not the same as nothing ever having happened in a town whose oldest streets were built long before anyone was keeping records.
Flood risk here lands middling, and the average flatters one part of town while flattering nobody in the other. Buy on the map rather than on the reputation, because in Brixham the two disagree by a couple of hundred metres.
