Strengths

• Links addresses to a range of current statutory geographies, providing authoritative administrative context.
• Produced by ONS Geography, the official geographic support unit for UK statistics.
• File size of 450 MB suggests a substantial dataset covering Great Britain.

Limitations

• Data is from October 2018; its freshness for current applications should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
