Will your address flood, and can you get it insured and mortgaged?
Enter an English postcode and see free of charge its flood zone and the risk bands for rivers, the sea and surface water. What the numbers mean, which past floods were recorded around the property, which warning areas cover it and what to ask your insurer, surveyor and solicitor is in the report for that one point.
A flood is the most expensive thing that can happen to a home, and a flood zone or a surface water flow path can change the insurance terms, the mortgage offer and the resale price. The report gathers the Environment Agency data for your address before you commit; it is not a substitute for a flood search from your conveyancer.

- Every recorded past flood and the flood warning areas that cover the address, with dates, sources and causes where the Environment Agency has them

Frequently asked questions
Is BB3 in a flood zone?

Is surface water flooding a risk in BB3?
2 of the 5 sample points (40%) sit in an area the Environment Agency rates at least low risk for surface water flooding, and 1 of those at medium or high risk. Surface water risk is highly local: it follows dips, underpasses and the line of old streams, so look at your own postcode.
