Frequently Asked Questions

What is the Standard Industrial Classification (SIC) code?

A Standard Industrial Classification code or SIC code is a 5-digit code and describes the main business activity of a company.
This provides Companies House, the Office for National Statistics (ONS) and other government bodies with a comprehensive framework of data and insight into UK businesses and industries.
Even if your company is dormant (99999) or non-trading (74990) you'll still need to provide the appropriate SIC code.

How many SIC codes does my company need?

The vast majority of companies select a single SIC code which they feel describes the nature of their business. However, you can choose up to four SIC codes, so if a single code just can’t on its own describe what the company does, you can choose to include more than one.

Why Would You Need to Change Your SIC Code?

There are many reasons why you may want to change your SIC code:

- Your principal business has changed
- You entered the wrong SIC code when you established your company. This is easy to do if your business carries out multiple forms of work. And many of these SIC codes are extremely vague.
- Your business has expanded and you want to incorporate new SIC codes into your company. You can actually have up to four industrial SIC codes.
