Taking the step to form a private limited company is an exciting milestone. It gives your business a professional identity, protects your personal assets, and opens up new opportunities.

Business and financial paperwork verification featuring a close-up of hands working on a contract. Ideal for corporate, investment, and legal consulting.

When it comes to the paperwork, you might be wondering: what's the best way to register with Companies House? The process is more straightforward than you might think. You have four main paths to choose from.

What You'll Need Before You Start

Regardless of which method you choose, you'll need to have a few key details ready:

Unique Company Name

Check the Companies House register to ensure your chosen name isn't already taken or too similar to another

Registered Office Address

Must be a physical UK address where official mail can be sent. It will be publicly available

Director(s)

At least one director needed. Full name, date of birth, nationality, occupation, and residential address required

Shareholder(s)

At least one shareholder (can be same as director). Decide on number and value of shares

SIC Code (Standard Industrial Classification)

Code that identifies what your company does. Find the right one on the government's condensed list

Once you have this information, you're ready to choose your registration method.
