PromptFiling — UK 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.
