SIC (Standard Industrial Classification) codes are used as a framework for classifying business activities based on a list of numeric codes. SIC Codes are used by Companies House and HMRC as a means to identify and group businesses by the sort of products and services they supply.
SIC Codes are used as part of the VAT registration process by HMRC. The SIC Code list was last revised in 2007.
