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.
