What is an SIC code?
Standard Industrial Classification (SIC) codes are mainly used for statistical purposes by the government. There are dozens of different codes covering different industries from construction through to computing. When setting up a limited company you simply have to pick an SIC code that fits your business. This lets the government know how many construction businesses are being setup each year compared to the number of computer businesses.
The requirement for new limited companies to provide an SIC code was also introduced in June 2016. Previously companies only had to state their SIC code at the end of their 1st year.
