Company Deadlines
1 credit / callEvery date a UK company has, in one call, and a calendar feed you subscribe to.
Accounts, confirmation statement, identity-verification dates (as counts), ICO fee renewal, payment practices and gender pay gap reporting: one sorted list with days left, and a free calendar feed.
Companies House gives two dates. A company has more: accounts and the confirmation statement, yes, but also each director's and PSC's identity-verification date (the last of them falls on 1 December 2026), the ICO data protection fee renewal, and, where the company reports them, the next payment practices report and the next gender pay gap report. This endpoint reads all of them from the public registers and services we already hold and gives them back as one sorted list with days left, overdue first. It also gives you a calendar feed address for the company, free, that Outlook, Google Calendar and Apple Calendar refresh by themselves. People are counted, never named.
what you’d build with it
Accountants' practice tools
Every client company's dates in the tool your staff already live in, with the ID-verification countdown their own software doesn't show.
Client reminders
A practice subscribes each client's feed and the dates sit in the shared calendar; a reminder goes out before the register says overdue.
Onboarding checks
A supplier or borrower with an overdue filing shows it on day one.

…Abbreviated. The full example, every endpoint and runnable code are in the implementation guide above; the integration pack downloads beside it. No account needed to read any of it.
Why developers pick it
Beyond the register's two dates
ID verification per person, the ICO fee, payment practices and pay gap reporting: dates nobody else joins up.
A feed, not a lookup
One free calendar address per company that refreshes itself twice a day; the dates live where the work is planned.
Honest statuses
overdue, due soon, upcoming, ok, or 'check' when a register entry couldn't be found: never a guess dressed as a date.
