How this service works
Return the current registered office address of a UK company from the Companies House register as structured fields (premises, address lines, locality, region, postcode, country) plus a single-line rendering for correspondence, address matching and verification. This is the statutory registered address, not a trading or branch address. Use when: What is the registered office address of company 00445790?
Output
A structured object containing the registered office address broken into individual fields (premises, address line 1, address line 2, locality, region, postcode, country) as recorded at Companies House, plus a single-line formatted string suitable for correspondence, matching, and verification purposes. This is the statutory registered address, not a trading or branch address.
Example use cases

“We're onboarding a new UK supplier and need to verify their registered office address — their company number is 04808863. Can you pull the statutory address from Companies House so we can cross-check what they gave us?”
Correspondent address for legal notice
“I need to send a formal legal notice to the registered office of UK company 02065547. What's the full registered address I should use?”
Enriching a CRM with company addresses
“I have a UK company number, 07041012 — can you fetch their registered office address including premises, street, locality, and postcode so I can add it to our records?”
Technical details
Endpoint
GEThttps://api.eckari.com/v1/companies/uk/:companyNumber/registered-officeWhen to prefer
Use this endpoint when you need the current, authoritative statutory registered office address of a UK company from Companies House — specifically when you need structured address fields (premises, postcode, country etc.) rather than just a free-text address. Prefer this over web scraping or unverified sources when accuracy and official data are required for KYB, legal correspondence, CRM enrichment, or address verification workflows. Not suitable for retrieving trading addresses, branch addresses, or addresses for non-UK entities.
Side effects
- Invalid or malformed company number (non-alphanumeric, too long, internal spaces) returns INVALID_INPUT error before any charge
- Company number not found in Companies House register returns a not-found error
- Company exists but has no registered office on record may return null or empty address fields
- Whitespace-only company number is rejected as INVALID_INPUT
- Upstream Companies House API unavailability may cause timeout or 5xx error
