How Long Does It Take to Set Up a Limited Company

Learn how long it takes to set up a limited company in the UK, what steps are involved and how to avoid delays

Setting up a limited company in the UK is a fairly straightforward process, especially when compared to other business structures around the world. But while it can be quick, the time it takes depends on how you apply, what information you have ready and whether there are any complications during the process.

This guide explains how long it takes to register a limited company, what steps are involved and how to make the process as smooth as possible.

How long does it take to register with Companies House?

If you apply online through Companies House using the standard formation process, your limited company can often be set up within 24 hours, sometimes even on the same day.

Applications are processed Monday to Friday during office hours. If you submit your application late in the day or outside working hours, it will be reviewed the next working day.

Key timeframes to expect:

  • Online application: Usually within 24 hours

  • Paper application (via post): Typically 8 to 10 working days

  • Same-day service: Available for an extra fee if submitted before 3pm (weekdays only)

Most new business owners choose the online route, which is cheaper and quicker than sending forms by post.

What information do you need to set up a limited company?

To avoid delays, make sure you have all the required details ready before starting your application. You will need:

  • A unique company name

  • A registered office address in the UK

  • At least one director (must be at least 16 years old)

  • Details of any shareholders and how many shares they hold

  • A statement of capital and company constitution (usually the default 'Model Articles')

  • SIC code to describe what your company does

  • A valid email address

  • A method of payment for the Companies House fee (£12 for online applications)

If you are appointing someone as a director or shareholder, you will also need their full name, address, nationality and date of birth.

How to register your company

There are three main ways to set up a limited company in the UK:

  1. Register directly with Companies House using the online service on GOV.UK

  2. Use a company formation agent who submits the application on your behalf

  3. Ask your accountant to handle it as part of their setup service

The quickest and most cost-effective method is registering directly through Companies House.

What could delay the process?

Although most companies are registered quickly, there are a few common issues that can cause delays:

  • Choosing a company name that is too similar to an existing one

  • Entering incorrect or incomplete information in your application

  • Trying to register a sensitive or restricted word (such as “Royal” or “Bank”)

  • Using a non-UK address for the registered office

  • Filing by post instead of online

To avoid these problems, double-check your application and make sure all details are accurate.

Can I speed up the process?

Yes. If your application is urgent, you can use the same-day incorporation service, which costs £100. To qualify for same-day registration, you must:

  • Apply online through a formation agent or directly via Companies House software

  • Submit your application before 3pm on a working day

  • Include “same day” in the subject line of the email if filing through software

  • Ensure all documents are complete and correct

This service is often used when legal or financial deadlines require a company to be set up immediately.

What happens after the company is registered?

Once your application is approved, you will receive:

  • A certificate of incorporation

  • Your company registration number (CRN)

  • Confirmation of the company name and date of formation

  • Copies of your memorandum and articles of association

You can then open a business bank account, register for corporation tax with HMRC and start trading. If your turnover is expected to exceed £90,000, you may also need to register for VAT.

Do I need to wait for anything else before trading?

No. Once you receive your certificate of incorporation, your company is legally formed and you can begin trading right away. However, it is advisable to:

  • Open a dedicated business bank account

  • Set up bookkeeping or accounting software

  • Register for PAYE if you plan to pay yourself or any employees

  • Register for VAT if required

  • Get business insurance if your industry demands it

Final thoughts

Setting up a limited company in the UK is a fast and efficient process. Most online applications are completed in 24 hours, with many approved on the same working day. Delays are rare if you have all your information ready and follow the correct process.

By planning ahead, checking your details and choosing the online route, you can have your company up and running in no time. If you are unsure about any part of the process, a formation agent or accountant can handle it for you with minimal hassle.
