Toddington has almost no risk from rivers or the sea, and a moderate risk from rain with nowhere to drain. About one postcode in a hundred is in the highest river flood zone. Once surface water is counted, about one in ten is flagged high on some measure. Nobody in the area has a recorded flood on file. Whether a house is at risk depends on which street it is on.
The Environment Agency's river-and-sea mapping puts about 1% of the area's postcodes in flood zone 3, the highest-probability band, and none in flood zone 2, the medium-probability fringe outside it. On the river measure, almost all of Toddington and its neighbouring villages sit outside both zones. Rivers barely trouble the village.
Rain is the problem. Surface water collects wherever the ground and the drains can't keep up, whatever the height above a river, and the Environment Agency maps it separately. It makes up most of the risk in the area, and it shows up in the postcode figures below, not in the river zones.
With climate change factored in, the Environment Agency's zone share for the area stays at about 1% of postcodes. On its projections, the river risk doesn't grow much.
For most houses here, river flooding shouldn't affect insurance much. Where surface water is a factor, an insurer will price the specific postcode, and two houses on the same road can get different quotes. Get an indicative insurance quote on the exact address early on. That costs nothing and settles the question faster than any map.
Across the area's postcodes, about 10% rate high on at least one flood measure, 13% medium and 36% low, where the measures cover rivers, the sea and surface water together. A postcode counts here if any single measure flags it, so this is the widest net on the site. A low rating means a small chance of flooding in any given year, and a small chance still means the house can flood.
Counting properties is more concrete. The Environment Agency's rivers-and-sea mapping lists 27 properties across 3 postcodes in the area, which are the only postcodes with any river or sea risk at all. Of those, 4 properties are at high risk, 3 at medium and 1 at low, and just 1 of the high-risk ones is a home. That is a very short list for an area of this size.
The mapped high-risk extent covers about 1% of postcodes with flood defences left out of the model and about 1% with them included. Adding the defences to the model makes no difference to the share, and that suggests there's little in the way of engineered protection here to count. A seller describing a house as "defended" would need to say which defence and where, and on these numbers nobody can.
The nearest tide gauge is in Portsmouth, where the sea rose by about 2 millimetres a year between 1962 and 2023. That is a long way to send an inland Bedfordshire village to find a sea level reading, and it's about as relevant as it sounds.
The Environment Agency has no recorded flood events anywhere in the area. That is reassuring, and it is about as much reassurance as a flood record can give. It means nothing has been mapped. It can't prove that a cellar on a low corner of the village has never had water in it.
Toddington's flood risk is middling. Rivers are close to a non-issue, but surface water is common enough across the area that the exact house needs checking.
