How do I register a limited company?

If you are starting a business as a limited company one of your first steps will be to register it. Once your company is incorporated, it becomes a separate legal entity with its own legal and tax responsibilities.

This guide explains how to register a limited company, the information you’ll need to provide and what happens after your company has been incorporated.

How do I register a limited company?

You can register a limited company yourself or use a company formation agent or accountant to complete the process for you.

The most common way to register is online through Companies House. You can also apply by post, although this usually takes longer.

When your application is approved, Companies House will issue a Certificate of Incorporation, confirming that your company has been legally formed.

How much does it cost to register a limited company?

Companies House charges a fee to register a limited company. The amount you pay depends on how you apply and the service you choose.

For the latest incorporation fees, including online, paper and any expedited services, see the official Companies House fees.

If you use a company formation agent or accountant to register your company, they may charge an additional fee for their services on top of the Companies House registration fee.

 

How long does it take to register a limited company?

Online applications are usually processed within one working day, although this can vary depending on demand and whether Companies House needs further information. Paper applications generally take longer.

How do I update my company details if they change?

If certain details about your company change after it has been incorporated, you must notify Companies House. Depending on the change, there may also be a requirement to inform HMRC.

Examples of changes you may need to report include:

  • appointing or removing a director;
  • changes to a director’s personal details;
  • changing the company name;
  • changing the registered office address;
  • changing the company’s accounting reference date;
  • changing where the company’s statutory records are kept; and
  • changes to the company’s share capital or shareholdings, such as issuing new shares.

Many changes can be reported online through Companies House.

If the change also affects your company’s tax affairs, you’ll need to notify HMRC separately using the appropriate online service.

Do I need to register for Corporation Tax?

Yes. If your company starts carrying on business, you must register it for Corporation Tax with HMRC.

A company is generally considered to have started doing business when it begins activities such as:

  • buying or selling goods or services;
  • advertising or marketing the business;
  • employing staff;
  • entering into business contracts; or
  • earning income.

You should register within three months of starting business activities. Failing to do so may result in penalties.

To register, you’ll need your company’s 10-digit Unique Taxpayer Reference (UTR). HMRC will normally send this to your company’s registered office after it has been incorporated.
