Standard industrial classification of economic activities (SIC)

A condensed list of SIC codes for providing Companies House with a description of your company's nature of business.



This publication shows a condensed list of the Office of National Statistics (ONS) codes used to classify business establishments and other standard units by the type of economic activity in which they are engaged.
