JSON Parquet

Companies House data,
ready to import.

Bulk snapshot files of the full Companies House register — the fastest way to bootstrap your database. Pair with companies.stream to keep it current with real-time updates.

Same format as the stream — no translation needed.

The snapshots use the exact same JSON structure as companies.stream. Bootstrap your database from a snapshot, then switch straight to the stream — no schema mapping, no ETL, no bulk CSV reformatting.
