Running a company in the UK is not only about selling products or keeping accounts. Sometimes, businesses also need to change their names. Maybe you rebranded, found a better name, or want to refresh your image. To make this change legal, you must use the NM01 form.
In this article, we will explain what the NM01 form is, why it matters, how to file it, and how it connects with things like confirmation statements and working with a VAT registration accountant.
What Is the NM01 Form?
The NM01 form is the official document you file with Companies House when you want to change the name of your limited company.
It is not enough to just use a new name in your marketing. The law requires you to update your company’s legal name in the official register. The NM01 form makes sure your new name is approved and recorded.
When you file the NM01 form, you must also pay a fee to Companies House. Once approved, your new name becomes official and will show up on all records.
Why Do Companies Change Their Names?
Changing a company name can happen for many reasons:
Rebranding – To give your business a fresh look.
Mergers – When two businesses join and want a new joint name.
Clarity – To make the name more simple and easy to remember.
Market Shift – To match new products or services.
Legal Issues – If your old name is too close to another registered company.
No matter the reason, the NM01 form is the legal path to make it happen.
How to File the NM01 Form
Filing the NM01 form is simple if you follow the steps carefully:
Choose your new name – Make sure it is unique and not too similar to another company.
Check availability – Use the Companies House name search tool.
Fill out the NM01 form – You can file online or by post.
Pay the fee – Standard service is cheaper, while same-day service costs more.
Wait for approval – Companies House will check and confirm the change.
Once accepted, your certificate of incorporation will show the new company name.
Link Between NM01 Form and Confirmation Statements
After changing your company’s name, you also need to update it in your confirmation statements.
A confirmation statement is a yearly report that gives Companies House updated information about your company. It includes:
Company name.
Directors and shareholders.
Registered office address.
Persons with significant control.
If you change your name using the NM01 form, but forget to update it in the confirmation statement, your records will look wrong. This can cause problems with banks, partners, and even legal penalties.
That’s why both the NM01 form and confirmation statements work together to keep your company details correct and trusted.
Role of a VAT Registration Accountant
Changing your company’s name also affects your taxes. Your VAT registration is linked to your company name, so once the NM01 form is approved, you may need to update HMRC records.
This is where a VAT registration accountant helps. They:
Update your VAT registration certificate with the new name.
Inform HMRC about the change quickly.
Make sure invoices show the correct business name.
Guide you on tax planning during rebranding.
Without an accountant, many companies miss these small details and face delays or fines.
Common Mistakes When Filing NM01 Form
Business owners sometimes rush the process and make mistakes, such as:
Choosing a name too close to another company.
Forgetting to update confirmation statements.
Not updating HMRC and VAT records.
Using the new name before approval.
Entering wrong details in the NM01 form.
Avoiding these mistakes saves time and keeps your company records clean.
Why Professional Help Matters
While filing the NM01 form may look simple, it affects many parts of your business. An accountant or company secretary can make the process smooth. They can:
Check name availability.
File the NM01 form correctly.
Update confirmation statements on time.
Manage VAT changes with HMRC.
Keep payroll and banking details accurate.
This support saves stress and ensures your business remains compliant.

Build a stronger image with your new name.
