A Standard Industrial Classification code (SIC) is used
by the Companies House to categorise the type of economic activities in which a business is involved. This information should be provided by all the businesses
at the time of company formation, despite the fact of whether their business is
active or dormant.
Where can limited company SIC code be found?
You can get the suitable SIC code for your company in the latest version of codes (SIC 2007) that can be viewed online from the Office for National Statistics (ONS). A condensed version of the full list is available on the website of Companies House. You should use the appropriate code from the condensed list on your annual confirmation statement.
Can a company's SIC code be changed?
The SIC code can be changed at any time if your main business functions change. You simply need to find a suitable SIC code from the condensed list (or conversion Table if you are using a code from the 2003 SIC list) on the website of the Companies house and give it on the next confirmation statement.
What happens if a wrong SIC code is provided for the limited company?
What SIC code should one use if the company is dormant or non-trading?
Dormant companies should choose SIC code 99999, and non-trading companies should use SIC code 74990.
