United Kingdom — Companies House Lookup

Live, direct-to-government access to Companies House (UK Department for Business and Trade).

Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on United Kingdom.

What you get

• Direct query to Companies House. Every tool call hits Companies House (UK Department for Business and Trade) at the moment you ask. No nightly scrape, no aggregator middle layer.
• Unmodified responses. Field names, status codes, and (where available) raw filing bytes are returned exactly as the registry's own system emits them.
• Native ID format support. 8-character alphanumeric (e.g. 00445790 for Tesco PLC, 08804411 for Revolut Ltd).
• Sample entity: Revolut Ltd.

Available tools (jurisdiction = GB)

search_companies, get_company_profile, get_officers, get_persons_with_significant_control, get_charges, list_filings, get_financials, fetch_document, search_officers, get_officer_appointments

For every tool, pass jurisdiction: "GB" (case-insensitive).

Quirks specific to United Kingdom

• PSC Register data is publicly accessible — no AML gating in the UK.
• nature_of_control strings are stable enums (e.g. ownership-of-shares-75-to-100-percent, voting-rights-25-to-50-percent) — useful for downstream pipelines.
• Companies House preserves both legacy and current name spellings; we return verbatim.
• FC-prefixed numbers indicate UK branches of overseas companies — they typically don't file local accounts.
