Set up a private limited company

7. Register your company

You can register your company if you have everything you need to set up.

Register online

You can register online if your company is limited by shares and uses standard articles of association (‘model articles’).

It costs £12 and can be paid by debit or credit card or Paypal account. Your company is usually registered within 24 hours.


Register by post

You can register by post using form IN01.

Postal applications take 8 to 10 days and cost £40 (paid by cheque made out to ‘Companies House’).

You can be registered on the same day if you:

  • get your application to Companies House by 3pm
  • pay £100

Your envelope (and any courier’s envelope) must be marked ‘same day service’ in the top left-hand corner.

Send your application to the address on the form.

Other ways to register

You can also register:

If your company is based overseas, you’ll need to register as an overseas company. You can contact UK Trade and Investment (UKTI) for advice.

After you’ve registered

Once the company is registered you’ll get a ‘certificate of incorporation’. This confirms the company legally exists and shows the company number and date of formation.

You’ll also need to register for Corporation Tax within 3 months of starting to do business.
