UK Postcode Flood Risk Data For Long-Term Environmental Planning

Environment Agency flood risk data supports an interactive postcode search tool for embedding in third-party media. The dataset provides long-term flood risk assessments for areas around UK addresses, not immediate forecasts. The Environment Agency published this open data, with a last update in April 2026.

Use Cases

• Map long-term flood risk probability to postcode geographies for spatial analysis.
• Embed postcode-level risk data into third-party websites for public information tools.
• Analyze regional flood exposure by aggregating postcode risk scores.
• Link postcode risk data to the GOV.UK 'Check your long-term flood risk' service for user guidance.

Strengths

• Data is published by the authoritative UK Environment Agency.
• Designed for integration into interactive web tools and third-party media.
• Explicitly covers long-term risk, providing a distinct focus from short-term forecasts.

Limitations

• Specific data volume (rows, size) and column schema are unknown.
• Risk is defined for the area around an address, not the precise property location.
• Data is intended for a specific tool, which may limit its standalone structure.
