Step-by-Step Company Formation Checklist UK

2. Appoint directors/shareholders: Minimum one director (16+, natural person)—gather passport/ID, DOB, nationality, occupation, service address. Shareholders: details, share classes (e.g., 100 ordinary £1), allotment.

3. Secure registered office: UK postcode address accepting mail—virtual provider letter or lease/utility bill proof. No PO Boxes.

4. Select SIC codes: Primary/secondary from 1,141 options (e.g., 62012 software development)—use GOV.UK finder for accuracy.

5. Prepare governance docs: Signed memorandum (subscribers list); model articles or custom (solicitor-drafted £200+).

7. File online (£12): GOV.UK portal—upload scans if postal (£34). Receive CRN instantly.

Example: Bristol startup checks “InnoVentures Ltd,” appoints founder director (passport scan), virtual office, SIC 72190 research, model articles, files Tuesday—CRN noon, trades Wednesday. This checklist sequence guarantees 95% first-time approval.
