What details do I need to form a limited company in the UK?
Starting a limited company in the UK is a popular choice for entrepreneurs seeking limited liability protection and tax efficiency. But before you register, it’s crucial to gather the right details to ensure a smooth process. This guide breaks down everything you need to know, from company name rules to post-registration obligations.
What is a Limited Company?
A UK limited company is a legally separate entity from its owners (shareholders) and managers (directors). The two most common types are:
- Private Company Limited by Shares: Ownership is split into shares, and liability is limited to the value of unpaid shares.
- Private Company Limited by Guarantee: Members guarantee a fixed amount if the company dissolves (common for non-profits).
Key benefits include personal asset protection, professional credibility, and potential tax advantages.
