How to Update Your Company’s SIC Code — Step-by-Step Guide 2026
A **SIC Code** (Standard Industrial Classification) is a 5-digit number that tells the UK government what your company actually does. When you first incorporated your UK Limited Company via Eteform, you selected at least one code. However, as your business grows or pivots (e.g., from consulting to e-commerce), your original code may no longer be accurate. Updating your SIC code is a vital compliance step to ensure your records with Companies House and banks match your actual activity.
In this guide from Eteform.com, we explain how and when to update your company’s classification.
Why Update Your SIC Code?
- Banking Accuracy: Banks like Wise or Revolut monitor your activity. If your code says “Education” but your bank statements show “Shoe Sales,” your account may be flagged for review.
- Government Statistics: It helps the UK government track economic trends correctly.
- Professional Credibility: When partners or investors look up your company on the public register, they should see a description that matches your current business model.
How to Change Your SIC Code (How-To)
Step 1: Find the New Code
There are over 700 codes to choose from. See our Comprehensive SIC Code Guide to find the one that best fits your new activity.
Step 2: Use Your Next Confirmation Statement (CS01)
Unlike a change of address or director, you do not need to file a separate form to change a SIC code. The change is officially made when you file your annual Confirmation Statement.
Step 3: Update Now (Optional)
If you need the change to show on the public record immediately (e.g., for a bank application), you can choose to file a Confirmation Statement early. At Eteform, we can handle this “Early Filing” for you.
