The Standard Industrial Classification, abbreviated as SIC, is a system for classifying industries by a five-digit code. In the United Kingdom, the SIC codes are used by government agencies and private organizations to categorize and analyze industries at various levels of detail. The codes are designed to promote uniformity and comparability in the presentation of statistical data related to economic activities.

Understanding SIC Codes: Simple Steps

  1. Identify Your Industry Sector: The first step in understanding SIC codes is recognizing the broad industry sector that your business operates within. SIC codes are organized into major groups such as Agriculture, Construction, Manufacturing, and Services, among others. Each of these is further divided into more specific categories.
    ​

  2. Find the Relevant SIC Code: Once you've identified your broader industry sector, you can search for the specific SIC code that applies to your business. The UK government's Companies House website provides a searchable database of SIC codes.
    ​

  3. Use the SIC Code: Businesses in the UK are required to provide their SIC code when registering with Companies House. This code is used for statistical analysis, to help in classifying business activities for tax purposes, and it can also affect which regulations might apply to you.

    • Even if your company is dormant (99999) or non-trading (74990), you'll still need to provide the appropriate SIC code. This ensures your business is properly classified from a regulatory standpoint and for statistical purposes.
      ​

  4. Stay Updated: SIC codes are periodically reviewed and updated to reflect changes in the economy and the emergence of new industries. It's good practice to regularly check if your business's registered SIC code accurately reflects your current main business activity.

Conclusion:

SIC codes are a standardized numerical system that helps categorize businesses according to their industry sector in the UK. Understanding and selecting the correct SIC code for your business is essential for compliance with legal requirements and for ensuring that your business is accurately represented in government statistics and analyses. For further guidance or to find your SIC code, visiting the UK's Companies House and ONS websites is a great starting point.
