SIC Code 77400

What is SIC code 77400?

SIC code 77400 is the Standard Industrial Classification code for leasing of intellectual property. Every UK limited company must register at least one SIC code with Companies House when it incorporates. The code tells Companies House what industry your business operates in.

This code falls under the Administrative and Support Service Activitiessection of the UK SIC 2007 classification system. If your company's activities have changed since incorporation, you can update your SIC code when you file your next confirmation statement.

When do you need SIC code 77400?

• ✓Incorporating a new company — you must choose at least one SIC code when you register with Companies House
• ✓Filing a confirmation statement — your SIC code is reviewed as part of the annual confirmation statement (CS01)
• ✓Changing your business activities — if your company now does something different, update your SIC code
• ✓Annual accounts — your SIC code determines which accounting exemptions may apply to your company

How to change your SIC code

You can update your SIC code when you file your confirmation statement through the Companies House WebFiling service. You can't change it at any other time — it's only editable as part of the CS01 filing.

You can register up to four SIC codes per company. Most companies only need one or two. Choose the codes that best describe what your company actually does — not what it might do in the future.
