UK Companies House KYB + Financials

KYB and financials for any UK company in one JSON: officers, PSC beneficial owners, status, charges, filing history, plus financials parsed from filed iXBRL accounts and deterministic rule-based red flags. Built for AI agents, KYB onboarding and due diligence. Never fakes a number — and flags when figures aren't current.

What it does

• Full KYB in one call — officers (current and historical), persons with significant control (beneficial owners), company status, outstanding charges (secured debt), and recent filing history, straight from the official registry.
• Financials from filed iXBRL accounts — turnover, profit, net assets, cash and more, extracted deterministically where the accounts are machine-readable.
• Honest about currency — when the latest accounts are filed as PDF only (common for large/audited filers), the Actor flags the figures as not the latest (isLatestFiling: false) instead of silently returning stale data.
• Rule-based red flags — dissolved/inactive status, overdue accounts or confirmation statement, insolvency history, outstanding charges, negative net assets, losses, and more — each explainable.
• Deterministic and auditable — KYB data is authoritative from the registry; financials are extracted, never estimated. No LLM guessing.

financials.coverage is full (turnover disclosed), partial (balance-sheet items only — typical for small/filleted filers), or unavailable (no machine-readable iXBRL). Always check isLatestFiling and asOf: if newer accounts exist but are PDF-only, the figures shown are the most recent that could be machine-read, and this is stated explicitly.

Use it from an AI agent (MCP)

Once published, this Actor is callable through Apify's hosted MCP server (mcp.apify.com). Because Companies House requires a free API key, this Actor fits human-in-the-loop and configured-agent workflows (where the key is supplied once) rather than fully autonomous discovery. One company in, one combined KYB + financials + red-flags record out — ready to chain into screening.

Use cases

• KYB onboarding and supplier/counterparty due diligence on UK companies
• Pulling beneficial owners (PSC) and officers for downstream sanctions screening
• Monitoring company status, overdue filings and outstanding charges
• Feeding structured UK company data into an AI research or compliance agent

FAQ

How do I get KYB and financials for a UK company? Pass the company name or number as query plus your Companies House API key. The Actor returns officers, PSC, status, charges, financials and red flags in one JSON.

Do I need an API key? Yes — a free Companies House REST API key (Live application). Get one at developer.company-information.service.gov.uk.

Why are the financials sometimes older than the latest accounts? Many large or audited companies file their most recent accounts as PDF only, which isn't machine-readable. Rather than fake a number, the Actor returns the most recent machine-readable figures and flags isLatestFiling: false with an explanation.

Are the numbers estimated by AI? No. KYB data is authoritative from the registry; financials are extracted from filed iXBRL, never estimated.

Pricing & disclaimer

Pay-per-event: $0.04 per company lookup. No subscription. A free Companies House API key is required (the key is free; Apify charges only the per-lookup event).

KYB data is authoritative from the registry; financial figures are extracted from filed iXBRL accounts on a best-effort basis and may not reflect the most recent accounts if those are filed as PDF only. Informational only, not investment or legal advice.
