We're buying a house which appears to be in a siginificant flood risk area (according to the environmental reports). It's on the Somerset levels. Is there any way of finding out if the property has actually flooded before (the vendors say it hasn't, but obviously they would say that!) My DH is now getting quite worried about buying it, because of the flood risk (1 in 75 chance), and also because of global warming meaning it becomes more likely to flood in the future. Any thoughts?
