Why You Should Check Your Company Details
The company details held by Companies House are what identify your business to the public, to HMRC and to anyone who searches the company register. If those details are out of date or don’t match your own records, you risk delays, rejected filings and avoidable corrections.
Checking your company details regularly, and before you file your annual confirmation statement and company accounts, is one of the simplest ways to keep your company in good standing. It also helps you spot changes that need to be reported separately, such as a new company name, a new registered office or a change of director.
Company Details to Check
| Detail to check | What to confirm | Why it matters |
| Company name | Matches the registered name at Companies House exactly | A trading name or former name can cause a mismatch |
| Company registration number (CRN) | The unique number issued when your company was incorporated | Companies House and HMRC use it to identify your company |
| Registered office address | Spelling, postcode and full address are correct and current | Every company must keep a suitable registered office on record |
| Directors and shareholders | Names, appointments and shareholdings reflect your current setup | The public register should show who runs and owns the company |
| People with significant control | Anyone who owns or controls the company is listed correctly | Keeping this information accurate is part of your reporting duties |
| Business activity (SIC codes) | Codes describe what your company actually does | They form part of your public company record |
Check Your Company Name and Registration Number
Start with your registered company name and registration number. The name should appear exactly as it is listed at Companies House, which matters most if your company has changed its name or trades under a different one.
Your company registration number is the unique number given to your business when it was incorporated. Before you submit anything, make sure you haven’t used:
- A trading name instead of the registered company name
- A previous company name
- An incorrect registration number
Check Your Registered Office Address
Your registered office address is one of the most important company details to verify. Every company must maintain a suitable registered office address with Companies House.
- If you’ve moved since your last filing, confirm the new address has been formally updated.
- Check the spelling, postcode and other address details.
- If the Companies House record hasn’t been updated, resolve the address change before you confirm your details.
Check Your Officers, Ownership and Business Activity
Your confirmation statement is also the point where you confirm who runs and controls your company and what it does. Review your directors, shareholders, people with significant control and SIC codes, and make sure they reflect how your company operates today.
Keep an Eye on Your Company Accounting Dates
Your company details also include your accounting reference date, which determines when your annual company accounts and Corporation Tax return are due. If your company has recently changed or shortened its accounting period, or has only just been incorporated, double-check that the dates on record are correct so you don’t miss a deadline.
if you find any of your details are incorrect or out of date, you can easily update them either by your annual confirmation statement or via Companies House website
Conclusion: Confirm Your Company Details with Confidence
Accurate company details keep your public record correct and help you avoid delays and rejected filings. Before you file your confirmation statement, take a few minutes to compare your details with what Companies House has on record, and update anything that has changed.
