UBO Ownership Tree — UK PSC Beneficial Ownership Chains

Independent tool built on public UK Companies House (GOV.UK) data. Not affiliated with, endorsed by, or connected to Companies House or GOV.UK.

Extract beneficial-ownership chains straight from the official UK Companies House persons-with-significant-control (PSC) register — no API key, no login, no scraping of paid data feeds — and turn any UK company into a complete ownership tree. Give the actor a company name or number and it walks the corporate PSC chain level by level, returning flat one-record-per-owner output: owner name, owner kind (individual or corporate), nature of control, direct vs indirect ownership, chain level, and a source URL for every record — exported to CSV, Excel, or JSON.

Why UBO Ownership Tree?

• 🔎 Verify who really owns a UK company — walk corporate PSCs up the chain instead of stopping at the first layer, the way compliance teams and analysts need it.
• 🛡️ KYB/UBO checks from the official register — auditors, banks, insurers and fintechs get source URLs on every record for audit trails.
• 💼 Flat one-record-per-owner output — import straight into Excel, your CRM, or a KYB pipeline with zero post-processing.
• ⚡ No API key, no login — reads the public Companies House PSC pages directly; cap the bill with maxResults.
• 🔗 Source URLs on every record — click through to the exact PSC page the record came from.

Use cases

• KYB / compliance: beneficial-ownership verification, sanctions-adjacent screening, audit-ready evidence with source URLs.
• Lead generation: map who owns target accounts before outreach — account managers and SaaS sellers chase the real decision-maker.
• M&A / market research: understand group structures behind UK companies at a glance.
• Journalism / due diligence: trace indirect ownership through holding companies.
