FAQ
What is a SIC code UK?
The Standard Industrial Classification (SIC) code is a five-digit numerical code that categorises the industry and business activity to which your company belongs.
Why do I need a SIC code?
UK government agencies like Companies House and the Office of National Statistics use SIC codes to identify, categorise, and monitor which areas of the economy are growing and in decline. So you have to provide at least one SIC code for your business in the stage of registering your company.
How do I look up a company's SIC code?
You can search for SIC code for your company in the condensed list of SIC codes provided by Companies House or use our handy free online tool above.
Can I have multiple SIC codes for my business?
You may register a company with up to four SIC codes when applying to Companies House.
What is a NAICS Code? How does it differ from SIC?
The North American Industry Classification System (NAICS) replaced the SIC system in the 90s. This system is used only by United States, Canada, and Mexico. The UK government does not use this classification.
Can I change the SIC code?
Yes, and you don't even have to give a reason why you want to change your SIC code. You need to file a Confirmation Statement (previously known as an Annual Return) to change the SIC code. This form provides the most up-to-date information about businesses to Companies House to be included on the public register.
