Flood Risk FAQ
What flood risk zones exist in the UK?
The Environment Agency categorises flood risk into four types: river (fluvial), surface water (pluvial), coastal (tidal), and groundwater. Each has risk levels from very low to high, based on the probability of flooding in any given year.
Does flood risk affect property value?
Yes — properties in high-risk flood zones typically sell for 10-15% less than comparable properties in low-risk areas. Insurance costs are also significantly higher. Flood risk is a material consideration that must be disclosed during property sales.
Can I access flood risk data via API?
Yes — the Homedata API provides flood risk assessment, noise levels, landfill proximity, and environmental scores for any UK property via UPRN. Free tier: 100 calls/month. Get your API key.
