Who is this for?

  • Founders who want a UK Ltd quickly with minimal admin
  • Remote founders who need a registered office address and mail handling
  • Businesses that want a reliable compliance plan from day one

Step-by-step: how to register online (practical flow)

  1. Choose name + structure: UK Ltd is the most common for trading.
  2. Confirm registered office: compliant UK address (service address if needed).
  3. Confirm directors/PSCs + shares: keep it clean and accurate.
  4. Submit filing: we prepare and file with Companies House and confirm the result.

Real example (online registration checklist)

Typical “ready to file” list:

  • 3 name options
  • Director/PSC details (and documents if verification applies)
  • Registered office plan
  • Share ownership plan
  • What the company does (SIC codes)

Common mistakes to avoid

  • Last-minute address decisions: registered office is required to incorporate.
  • Inconsistent director/PSC details: mismatches create delays and rework.
  • Overcomplicated shares at day one: start simple unless there’s a clear reason.
  • No plan for filings: confirmation statements and accounts deadlines still apply.
