Can You Change Your Company Name?

Absolutely! As a limited company registered with Companies House, you can change your business name at almost any time, for a variety of reasons. There are, however, specific legal steps you’ll need to follow so that your new name is recognised officially-and so that all your contracts, tax affairs and customer relationships continue smoothly.

It’s important to remember that your company’s name is a legal identifier. That means changes must be properly approved within your business, submitted to Companies House, and reflected across all your key records.

Why Might You Want to Change Your Company Name?

There are lots of good reasons business owners decide to change their company’s name, including:

• Rebranding to reflect new products, services or business direction
• Merging with another business or acquiring a brand
• Resolving trademark, legal or reputational issues
• Securing a more memorable or marketable name
• Expanding into new markets or locations

No matter the reason, it’s vital to manage the name change process carefully to avoid confusion, contractual issues, or accidental non-compliance with the law.

How To Change Your Company Name: Step-By-Step Guide

Below, we’ll break down the main steps involved in changing a company name in England and Wales. These apply to most private and public limited companies, but if your business is structured differently (for example, as a partnership or sole trader), the process will be different-check our guide on business structures for more info.

1. Check Your Company Constitution and Shareholder Approval

Before anything else, you need to make sure your company has the authority to change its name. This usually means:

• Checking your company’s Articles of Association for any special rules around changing the company name (most allow for it, but some may require extra steps or approvals)
• Obtaining the correct authorisation, which is typically a special resolution (at least 75% of shareholder votes need to approve the change)

Sometimes, your company’s directors may have the power to approve a name change, depending on your Articles. If you’re unsure, consider seeking advice or a review of your Articles of Association.

2. Choose a Suitable New Name

This is where creativity meets compliance! You can select any name, but Companies House sets some key restrictions. Your new company name must:

• Be sufficiently different from already registered company names
• Avoid suggesting connections to government, public authorities, or professional bodies (unless you have permission)
• Not be offensive, misleading, or include sensitive words or expressions without approval

Check the Companies House name availability checker to see if your new name is free to register. Also, consider searching the UK trade mark register, as picking a name already trade marked by someone else could lead to expensive legal disputes.

3. Pass A Special Resolution

Once you’ve settled on a new name, formally pass a special resolution. Usually, this means:

• Drafting the resolution wording stating that the company name is to change
• Arranging a shareholder meeting (or using a written resolution process as permitted in your Articles)
• Recording the outcome in writing, including details of the votes cast

You need at least a 75% majority to pass the resolution. Keep a signed copy of the resolution for your records and to submit to Companies House.

4. File the Name Change with Companies House

The main legal step in a company name change is to notify Companies House and get their formal approval. Here’s how:

• Complete Form NM01 (Notice of Change of Name by Resolution)
• Attach a copy of the signed special resolution
• Pay the required fee (£10 for standard processing, or £50 for same-day service if you file online before 3pm)

You must file the documents within 15 days of passing your resolution. This can be done online or by post. Full details are available on the Companies House website.

5. Wait for the Certificate of Incorporation on Change of Name

When Companies House processes your application and approves the new name, they’ll issue an updated Certificate of Incorporation on Change of Name. This certificate is your legal evidence that your company can operate under its new name.

Don’t start using your new name on contracts and formal documents until you receive this certificate!

6. Update All Business Records and Public Materials

This is a step often overlooked after a company name change, but it’s just as important. Make sure you:

• Update your company’s statutory registers and records
• Change the name on your company seal (if you use one)
• Update business stationery, invoices, letterheads, contracts, and payroll documents
• Amend your website, email addresses, business signage and shopfronts
• Inform banks, HMRC, insurers, customers and suppliers of your new company name
• Update intellectual property (such as trade marks or patents), business licences, permits, and any industry registrations

It’s also a good chance to refresh your branding and marketing materials, so your customers and partners know who you are under your new identity.

What Legal Issues Should You Watch Out For?

While the mechanical part of changing a company name is relatively quick, there are some legal and regulatory pitfalls to avoid:

1. Intellectual Property Conflicts

Choosing a name that’s too similar to an existing trade mark or company name could open you up to costly disputes. Always check both the Companies House register and the UKIPO trade mark database.

More tips on protecting your brand can be found in our guide to protecting your intellectual property.

2. Sensitive Words and Regulatory Approval

Certain words like ‘Royal’, ‘British’, ‘Bank’, ‘Charity’, or those that imply a regulated activity, need formal permission from relevant government departments or industry bodies. If your chosen name falls into this category, you’ll need extra documentation, and approval can take longer.

3. Contracts and Existing Agreements

If you have ongoing contracts, agreements, or lease arrangements under your old company name, review whether you need to notify other parties or sign a formal amendment or deed of variation.

This helps ensure continuity of your legal obligations and minimises the risk of contractual confusion or disputes down the line.

4. Tax, Banking, and Licences

HMRC and your bank must be updated about your name change. You may need to provide a copy of the new Certificate of Incorporation on Change of Name for their records.

It’s also essential to update any business licences, permits, or regulatory registrations. Trading under an old name could make you non-compliant or even void certain insurances.

Common Questions About Changing a Company Name

Let’s address some of the worries business owners often have about this process:

How Long Does It Take?

Filing a change of company name online is relatively quick-often within 24 hours for the standard fee, or by the end of the same working day for the fast-track service (if submitted before 3pm and you pay the same-day fee). Paper applications take longer, so if speed matters, online is best.

How Much Does It Cost?

• £10 for standard processing
• £50 for same-day service

The payment is made to Companies House when submitting your NM01 form. If you’re unsure about the paperwork or your company’s particular circumstances, investing in legal support can help avoid rejected filings or costly mistakes.

Do I Also Need to Register a New Trade Mark?

If your new company name is linked to your branding or logo, it’s a good idea to register a trade mark to protect your new identity, especially if you plan to market to the public.

What About Trading Names?

If you use a trading name (sometimes called a business name) that’s different from your registered company name, remember that these are not the same in law. Changing your company name does not automatically affect your trading names, but you may wish to align both for consistency and avoid confusion.

Be sure to check that your proposed trading name complies with the Companies Act 2006 and doesn’t infringe any other rights.

Do I Need to Tell Anyone Else?

Yes! After completion, you must notify:

• HMRC
• Your business bank(s)
• Existing suppliers, clients, and contractors
• Landlords and lenders
• Insurers
• Industry regulators
• The public, via your website and signage

Failing to update records can lead to practical and legal headaches, so set up a checklist and cover all your bases.

Do You Need Legal Help to Change Your Company Name?

Many companies handle a name change themselves, but legal support can be very helpful if:

• Your company structure or shareholdings make the authorisation process complex
• You’re unsure if your chosen name is available or carries legal risks
• You need to draft or update resolutions, contracts, or notify external parties properly
• You want to review your Articles of Association or update your Shareholders’ Agreement at the same time
• You plan to change other company details (like directors, address, or structure) in addition to the name

Lawyers can also help coordinate your change of name with other regulatory obligations, brand protection and intellectual property steps for a smooth transition.
