Use this when

When are this UK company's accounts due?
Are company 00445790's accounts overdue?
You need the accounting reference date (ARD) of a UK company, from which the register derives its filing periods.
What type of accounts did this company last file and for what period?
You are scheduling compliance follow-ups or detecting dormant companies (accounts type dormant).

Don't use this when

You need financial figures (turnover, profit, balance sheet) — not on the public register API.
You need the list of filed documents — use company.uk.filings with category accounts.
You only need whether the company is active — use company.uk.status.

If the user has asked you to inspect a specific website, page or URL, use your browsing tool instead — this capability only returns the Companies House Public Data API record.

Input

company_numberstringrequired

Companies House company number, also called the company registration number (CRN). Accepted shapes are the register's own — 1-8 digits (zero-padded to 8, e.g. 445790 → 00445790), one letter + 7 digits (R0000001), two letters + 6 digits (SC002180, NI000001, OC123456, OE000001), or the registered-society suffix forms (two letters + 5 digits + 1 letter; two letters + 4 digits + 2 letters). Case-insensitive; surrounding whitespace is ignored (which is why maxLength is 10); internal spaces and punctuation are not accepted. Any other value (for example PROBE) is rejected as INVALID_INPUT before payment and before any upstream call.

What the result means

company_numberstring

company_namestring

has_accounts_informationboolean

Derived; false when the register holds no accounts block for this company.

accounting_reference_dateobject, null

The register's accounting reference date (ARD) as a day and month with no year: the anchor Companies House uses to derive a company's accounting periods and filing deadlines. It is not the same thing as the end date of any particular set of accounts — a company filing to a 52/53-week calendar may make its accounts up to any date within seven days either side of the ARD, so read last_accounts.made_up_to for the actual period end. TESCO PLC's ARD is 26 February while its last accounts were made up to 28 February 2026.
