company
check_company_deadlines
Look up a UK limited company by company number (preferred — e.g. 01234567 or SC123456) or by name, and get its statutory Companies House deadlines: when annual accounts and the confirmation statement are due, days remaining, the automatic late-filing penalty for accounts, and dormancy signals from the public register. Free, no account; data from the official Companies House register.
late
uk_late_filing_penalties
The current Companies House late-filing penalty bands for annual accounts — private companies and public companies (plc) — the doubling rule for two late years running, and what missing a confirmation statement risks. Static reference — no lookup performed.
