Is it possible to change your company name?
Yes, you can change limited company name any time after you set up your company. UK law gives you this right under the Companies Act 2006.

How to change the name of an existing company?
According to the government of UK there are two main ways to change company name for a limited company. Each one has different steps and paperwork involved when changing business name:
1. By Special Resolution
This is how most companies do it. Your shareholders need to vote on the change company name.
What you need:
- At least 75% of your shareholders must agree.
- You can vote in a meeting or by written agreement.
- Once everyone agrees, you tell Companies House about the change.
Documents needed:
- Form NM01: This tells the government about your name change.
- Copy of your vote results: This proves your shareholders agreed to the change.
How to file:
- Online: £20 fee, takes about 2 days (same day service costs £83).
- By post: Send the form with a £30 cheque.
2. Through your Articles of Association
Some companies have special rules that let directors change a business name without asking shareholders first. If your company has this rule, directors can decide on their own.
What you need:
- Just a decision by your directors.
- No shareholder vote needed.
Documents needed:
- Form NM04: This form is for name changes done through company rules.
- Statement about the change: This confirms you followed your company’s rules.
How to file:
- By post only: Send form with £30 cheque.
What are the effects of a company name change?
Here’s something important, changing business name doesn’t create a new business. Your company keeps the same:
- Company number
- Start date
- All debts and contracts
- Legal responsibilities
Only the name changes. When Companies House approves your new name, they send you a “Certificate of Incorporation on Change of Name.”
This paper makes the change official and shows when it started. You must keep using your old name until you get this certificate.
What are the problems with name change?
While it’s generally easy to change a company name in UK, it’s important to be aware of some potential problems:
Availability of name:
Your proposed new name must not be identical or too similar to any existing registered company. Company House has the right to reject names that may cause confusion. Recent changes under the Economic Crime and Corporate Transparency Act 2023 Act have given the registrar even stronger powers to reject names that are designed to cause objectionable confusion or fraud.
Sensitive words:
There are some certain words and expressions such as Royal, British, Institute or Bank it require special permission from a government department to be used in a company name.
Updating information:
The biggest challenge comes after filing. You will need to update all your business documents and bank account and communications to the new name. This can be very time consuming and requires notifying all stakeholders such as customers, suppliers and HMRC.
What is the checklist for change in name of company?
To ensure a smooth transition, follow this simple checklist when changing business name:
- Check if your name is free: Use the Companies House website to see if another company already uses your chosen name.
- Get approval: Hold a meeting where 75% of shareholders vote yes, or have directors sign an agreement (if your rules allow this).

- Online: Use Companies House website (£20, takes 2 days).
- By post: Fill out Form NM01 or NM04 and mail it.

- Update everything: Change your name everywhere bank, tax office, contracts, website, business cards and tell everyone who works with you
