Risk review
A structured review across five sources with the questions to ask a seller, an insurer and the local authority — plus the note that official flood maps rarely model surface water well.
How the Flood Risk Self-Assessment works
- Work through each flood source separately; a property safe from the river can still flood from surface water.
- Check the official flood map for your country, and treat it as one input rather than the answer.
- Ask the seller and neighbours directly about history. Local memory routinely knows about flooding that appears on no map.
FAQ
Are official flood maps reliable?
For river and coastal flooding they are generally good. Surface water flooding — the kind that comes from overwhelmed drainage during heavy rain — is much harder to model and is frequently understated or absent.
What should I ask a seller?
Whether the property has ever flooded, whether a claim has been made, and whether flood insurance has ever been refused or loaded. In many jurisdictions there is a duty to disclose known flooding, and the answer should be in writing.
Is this a formal assessment?
No. It structures your own review and points at the authoritative sources. A formal flood risk assessment for planning or insurance is a professional survey, and lenders may require one.
