Your limited company must specify a SIC code when completing your Confirmation Statement for submission with Companies House. You must choose the SIC codes that closely match your company’s business activities.
What is SIC code?
SIC stands for The United Kingdom Standard Industrial Classification of Economic Activities. The SIC code is a pre-defined 5 digits numbers used in the categorisation of UK businesses’ trading activities. Companies House works closely with the Office of National Statistics to collect statistical trading data for governmental analysis purposes.
Your company’s business activities
Your limited company can have more than one business activities.
Select the SIC codes that closely match your business activities when filling in your Confirmation statement.
For example, you may two main business activities under your company. Say, interior design service and letting of your own property. Your codes can be 74100 for specialised design activities and 68209 for Other letting and operating of own or leased real estate.
New SIC code has 5 digits
Companies House will reject your Confirmation Statement if you use the outdated SIC codes. The latest version is called SIC code version 2007.
It is recommended to file your Confirmation statement online if possible because the SIC codes in the Companies House’s web filing service is the updated version of the codes.
For examples, a dormant company must use the SIC code of 99999 and for non-trading company, the code is 74990.
Old SIC codes have 4 digits
If you are looking at 4 digits SIC codes list then you know it is not the latest version codes.
Take the same examples above, a dormant company under the old code would have code read 9999 and the new code is 99999. For a non-trading company, the old code was 7499 and the new code is 74990.
Convert old SIC to new SIC code
Let say, your current business activity is buying and selling your own property for a profit. The code to use under the old code is 7012 for buying & sell own real estate.
When filing your confirmation statement using the 2007 version of SIC codes, you would choose the code 68100 with the description buying and selling of own real estate.
Another example for you. If your company was set up to manage a residential property, the old code was 9800 for residents property management and the new code is 98000 with the exact same description.
Describe your trading activity
Last but not least, if you are unable to find suitable SIC code that closely matches your principal business activity, you must provide a brief description of your trading activity in your Confirmation statement CS01 part 1 form.
