Companies House

What SIC code should I use?

If you are filing your first annual return you will need to choose your SIC code to state your principal business activity. A SIC code (Standard Industrial Classification) is used to classify a company's nature of business or the type of economic activity in which they are engaged. Even if your company is dormant (99999) or non-trading (74990) this still has to be indicated by using the appropriate SIC code.

Companies House adopted the latest version of SIC 2007 on 1 October 2011 and all companies filing their annual return after this date need to supply the latest version of their SIC code. 

To help you select the most appropriate code for your business, please use one of the following links:
