UK Surface Water Flood Risk Extents for Spatial Planning, Present Day

UK land extents at risk from surface water flooding, provided by the Environment Agency. The data includes three flood probability scenarios: 0.1%, 1%, and 3.3% annual exceedance probability. It was last updated on 2026-05-29 and is designed for spatial planning, not individual property assessment.

Use Cases

• Assess regional flood vulnerability for land-use planning based on defined annual exceedance probabilities.
• Model surface water flood hazard for infrastructure projects based on spatial extents.
• Inform strategic environmental risk assessments based on area-wide flood risk layers.

Strengths

• Provides three specific flood probability scenarios: 0.1%, 1%, and 3.3% annual exceedance probability.
• Created and maintained by the authoritative Environment Agency, with a clear attribution statement.
• Data was updated on 2026-05-29, indicating recent maintenance.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data is explicitly not suitable for assessing risk to individual properties.
