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.

Questions

Frequently asked questions

Is B1 in a flood zone?

None of the 5 sample points we checked across the B1 postcode district fall in Flood Zone 2 or 3. That does not rule out a zone elsewhere in the district, because the sample is a handful of points and flood zones can be narrow. Check your full postcode to be sure.

Is surface water flooding a risk in B1?

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.

Which flood warning areas cover B1?

The Environment Agency issues flood alerts and warnings for named areas. Within about six kilometres of the centre of B1 these include River Rea at Highgate, Deritend and Digbeth, River Rea at Calthorpe and River Rea. You can sign up for free flood warnings for your address on GOV.UK.
