Future Flood Prevention

A few businesses in my area have been hit. One of them is relatively small, but it has been hit a couple of times by flooding, so the insurance premium is now running way into the thousands. The premises is also a mixed hereditament, which makes things more complicated, because people live where the business is. Surely, if Flood Re kicks in to help domestic premises, it should kick in for businesses as well. If there is a market failure, which I believe there is, and if it is suitable to have that sort of pooling of risk for houses, it should be the same for businesses.
