Guides

Plain-English guides to UK company filings, with the deadlines, fees and rules that matter — and, where it helps, a lookup against live Companies House data so you can check a specific company rather than read about it.

• Confirmation statement Deadline, cost and how to file the annual CS01 — plus a lookup for any company's own due date.
• SIC codes The full UK SIC 2007 list — search every code, see how many companies use it, and jump to the businesses behind it.
• Company status Active, dormant, liquidation, strike-off or dissolved — check any company's status, and see this month's UK insolvencies.
