This guide explains the full online incorporation process, required documents, costs, timelines, and common mistakes to avoid.


Can You Set Up a UK Company Online?

UK company formation can entirely be done online through Companies House or authorized online formation agents. After submitting the application your company is typically incorporated electronically, and documents are issued via email.

The UK system is designed to be digital-first and internationally friendly.


Step-by-Step UK Company Formation Online Process

Step 1: Choose Your Company Type

  • Business credibility


Step 2: Select a Company Name

Your company name must meet the following criteria:

  • Company registration number

  • Memorandum & Articles of Association

Your company is now legally active.
