Flood Risk Zones for London with Four Risk Categories

London flood risk zones are mapped based on data from the UK Environment Agency and the Centre for Ecology & Hydrology. Each spatial cell is assigned one of four flood risk categories, considering flood defences and their condition. The dataset is derived from the Environment Agency's national dataset and was last updated on 2026-06-24.

Use Cases

• Modeling property-level flood insurance premiums based on the four risk categories.
• Prioritizing infrastructure maintenance and flood defence investments based on risk zone data.
• Informing urban development planning and land-use zoning based on flood hazard maps.

Strengths

• Data originates from authoritative national sources: the UK Environment Agency and the Centre for Ecology & Hydrology.
• Risk assessment incorporates the condition of flood defences, likely providing a nuanced view.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
