The Companies House API gives websites and applications direct access to official UK company data — including registration details, officers, filing history, charges, persons with significant control (PSCs), and live company status. At CodeCareLabs we integrate this API to automate verification, reduce manual checks, satisfy KYC/AML obligations, and improve trust in your business workflows.
From simple lookups to fully-automated KYC workflows — these are the capabilities most clients ask for.
Real-time lookup against the official Companies House register — name, number, status in one query.
Company name, registered office, incorporation date, SIC codes, type, jurisdiction — full record retrieval where applicable.
Current and historical directors, secretaries, PSCs (Persons with Significant Control), and their roles.
Active, dissolved, liquidation, administration — track changes and trigger alerts in your system.
Annual accounts, confirmation statements, charge filings, officer changes — the complete document trail.
Implement the onboarding flows to verify business identity, screen against PSC data, satisfy compliance.
Company directories information powered by official data — auto-updating, always accurate.
Catch typos, format errors, and non-existent company numbers before they corrupt your database.
Replace screenshot-based verification with cryptographically-signed official verification using Companies House API.
If your platform touches UK businesses, Companies House data probably saves you hours of manual work every week.

We identify exactly which Companies House endpoints you need — search, profile, officers, filing history, charges, PSCs — to avoid over-engineering.
API authentication, rate-limit handling, retry logic, response caching, and encrypted credential storage — all built right.
Search boxes, profile cards, officer lists, status badges, alerts — designed to match your existing brand.
Sync to your database, trigger webhooks, populate records, generate PDF reports — whatever your workflow needs.

Staging deployment, production cutover, monitoring setup, and ongoing maintenance with optional SLA.
Three of the most common ways businesses turn Companies House data into measurable wins.
Auto-verify new business accounts in minutes instead of days. Customer enters a company number → we fetch and verify against Companies House → KYC checklist auto-completes → onboarding moves forward without manual review.
Build a branded UK company search tool inside your platform. Users type a name or number → autocomplete suggestions → click to view full profile, officers, filings, status. Embed in lead-capture forms, dashboards, or public-facing apps.
Auto-populate company data when adding new leads or accounts. One field (company number) → 5+ fields auto-filled (registered address, SIC codes, directors, incorporation date). Live syncing keeps records fresh as data changes at Companies House.
