How to Set Up a Limited Company Online: Full Guide for Entrepreneurs

So, you’ve decided to either set up a business or transition yourself from a freelancer to a limited company. That’s great, and in doing so there are a ton of advantages. But before you head to the Companies House website, there are a number of things to consider and steps to follow beforehand.

How to set up a limited company online

What Types of Limited Company Can Be Registered Online?

It’s important to understand the differences between private and public limited companies before registering your business. The main difference is that a public limited company can raise capital by selling shares to the general public, while a private limited company cannot. Before you set up a company online, make sure to also read about the two types of private limited companies.

Public Limited Companies, aka PLC

A public limited company must have at least two directors and a company secretary and have issued shares up to a value of at least £50,000. It will offer shares to the general public, and potentially the stock exchange.

Startup businesses will not usually structure themselves as a public limited company, and is more often reserved for larger, established companies who are recognised brands, and therefore more likely to attract interest and investment.

Private Companies Limited by Shares

This is the most common type of limited company in the UK, as it predominantly suits smaller, startup businesses.

Private companies often have a single shareholder, who is the original owner or sole trader, and therefore has full ownership and control. However, there is no limit on how many shareholders a company can potentially have.

As a business grows, there’s usually the need for an additional cash injection, at which point there may be the need for new shareholders. With additional shareholders, comes shared control, and - of course - shared profits.

There is also a third type of limited company:

Private Company Limited by Guarantee

This structure is generally reserved for non-profits such as charities and other not-for-profit organisations.

These companies don’t have shareholders and instead have guarantors who pay fixed contributions toward the company’s debt.

Unless you’re operating a non-profit, your business won’t be eligible to operate under this structure.

How Do You Register a Limited Company Online

There are three ways you can set up and register with Companies House:

  1. Set up a limited company online on the Companies House website, which can take just 24 hours
  2. By post using form IN01, which can take 8-10 days
  3. By using a company formation service such as Hoxton Mix

If you choose the latter option, you will have your limited company set up online in record time. Besides, company formation by Hoxton Mix also qualifies as the cheapest way to set up a limited company.

We have already posted material on how to register a company in the UK. Now, let’s go through the steps to create a limited company remotely.

  1. Choose the company type

Double-check if a limited company is right for you; you can also start a business as a partnership, a social enterprise, an overseas company, or an unincorporated association. 

  1. Choose the name

Pick a name that complies with the rules for company names and check if it’s available and doesn’t fall under existing trademarks.

  1. Decide on the shareholders, guarantors, and directors

Appoint individuals for key positions. 

  1. Designate persons with significant control

Identify your beneficial owners (more than 25% of voting rights) and include them in your company’s PSC register. 

  1. Prepare the legal documents

Create a memorandum and articles of association.

  1. Check which records you need to keep

Depending on the type of company you register, owners will have to keep different company and accounting records. 

  1. Register with Companies House

The final step to create a limited company online is sending registration forms to Companies House and applying for Corporate Tax (alternatively, with HM Revenue and Customs).

What info do you need to register your company?

In order to register your company, you’ll need the following:

  • Your company name
  • The names of your company directors
  • The names and addresses of your shareholders (as well as other security information, such as the town of birth or mother’s maiden name)
  • Memorandum
  • Articles of association
  • An address you’re happy to make public (as it’s published on the Companies House website)

How Much Does It Cost To Register?

It costs £12 when registering online, or when doing it by post, the registration fee is £40.

When using a company formation service with Hoxton Mix, prices start from just £10.

Do You Need To Register If You’re a Sole Trader or Freelancer?

If you’re a freelancer or sole trader you do still need to let HMRC know, so long as you’ve earned more than £1000 during the financial year. For more information check out our guide to registering as a sole trader.

Once You’ve Registered, Then What Do You Need To Do?

Once you’ve set up your limited company, you’re ready to start working on your business. Ensure you have a thorough business plan and keep full financial records.

However, you’ll also need to make sure you are making yourself as visible and accessible as possible, which means you need to consider:

  • Creating a brand identity, including logo, slogan etc
  • Setting up a professional website and bespoke email address
  • Sales and marketing
  • Building a team

Companies House and HMRC will send you correspondence to the address you provided during online registrations, so make sure it’s an address where you can regularly receive post or a virtual address that provides a mail forwarding service.

Possible Pitfalls of Setting Up a Limited Company Online

Below are some of the common mistakes people make when opening a limited company online:

  • Registering wrong company type
  • Making typos in filing and governance documents
  • Failing to include all shareholders and directors
  • Choosing the wrong company address
  • Failing to register for corporation tax
  • Not being prepared for financial admin and legal obligations
