A ‘SIC code’ is a Standard Industrial Classification code. These are used by Companies House to classify the type of economic activity in which a company or other type of business is engaged. This information must be provided by all companies at the time of company formation, regardless of whether the business will be active or dormant.
The Office for National Statistics (as well as a number of other government authorities) use these codes to collate important data about the various types of businesses operating and trading within the UK.
Where to find your limited company SIC code?
You can find the appropriate SIC code for your company in the latest version of codes (SIC 2007) which is available to view online from the Office for National Statistics (ONS). A condensed version of the full list is available on the Companies House website. You must use the appropriate code from the condensed list on your annual confirmation statement.
If your company is using an old SIC code from the previous 2003 version of codes, you must search the SIC Conversion Table to find the 2007 equivalent. You should provide the new code on your next confirmation statement.
Can I change my company’s SIC code?
Yes, you can change your SIC code at any time if your principal business activities change. Simply find the appropriate SIC code from the condensed list (or Conversion Table if you are using a code from the 2003 SIC list) on the Companies House website and provide it on your next confirmation statement.
There is no need to notify Companies House before the statement due date, but you can update this information free of charge at any time via WebFiling of software filing.
What happens if I provide the wrong SIC code for my limited company?
This is nothing to worry about. You will just have to change the code when it’s time to deliver a confirmation statement. Alternatively, you can amend the code immediately by updating your statement early.
What SIC code should I use if my company is dormant or non-trading?
Dormant companies should use SIC code 99999. Non-trading companies should use SIC code 74990.
