Sometimes you need to change the name of your company. This is a significant change because it impacts your brand, your messaging to your customers and needs legal and regulatory forms to filled in and filed at Companies House.
It’s straightforward to change the name of your company but there is a process to follow to ensure you comply with the regulations from Companies House and to make sure your itself is not badly impacted by any change. You’ll need board resolutions, shareholder approval, and proper notification to Companies House. Many business owners assume they can simply update their website and letterhead, but that’s just the communications to customers.
Here’s what you can expect: Companies House processes most name change applications within 48 hours, and electronic submissions often complete within 24 hours. The fees are straightforward too,£20 for online filing or £30 if you prefer posting your documents. Find out more at Companies House.
But can you change your company name whenever you want to whatever you want? Unfortunately, no. Your new name must be unique, meet legal requirements, and avoid trademark conflicts. It also can’t be offensive or confusingly similar to existing company names.
This guide walks you through every step of the UK company name change process. From checking eligibility requirements to updating all your business documentation after approval, you’ll know exactly what to expect and when to expect it.
Check if you can change your company name
If you’ve spent weeks brainstorming the perfect new name for your business, it would be incredibly frustrating to discover you can’t legally use the new name. The Companies Act 2006 sets clear rules about when and how UK companies can change their names – and understanding these requirements upfront can save you significant time and frustration.
When a name change is allowed
UK law gives companies two main routes to change their names. The first requires a special resolution with that 75% majority vote from members we mentioned earlier. The second option uses any specific provisions written into your company’s articles of association.
Here’s something many business owners miss: your new name isn’t legally recognised until Companies House officially registers it. This means you must keep using your old name on all business materials, websites, and signage for 14 days after approval.
Companies House gained stronger powers in March 2024 through the Economic Crime and Corporate Transparency Act. They can now reject name change applications when they suspect:
- The name might facilitate fraud
- The name contains computer code
- The name falsely suggests links to foreign governments or international organisations
Miss their 28-day deadline to change your name when directed? Companies House can simply assign your company number as your new name.
Types of companies that can change names
Nearly every registered UK company can change its name. This includes:
- Private limited companies (Ltd)
- Public limited companies (PLC)
- Companies limited by guarantee
The procedures stay largely the same regardless of your company structure—board approval, proper documentation, and official registration with Companies House.
Common reasons for changing a company name
Smart business owners don’t change names on a whim. They usually have solid strategic reasons.
Rebranding ranks as the top motivation. Companies reshape their brand perception or adapt to new business directions. Mergers and acquisitions also trigger name changes as combined entities create unified identities.
Other frequent catalysts include:
- Outgrowing your original name as you expand services or move from local to international markets
- Confusion with similar business names that dilute your message and create legal headaches
- Repositioning for new target audiences or business directions
- Practical ownership issues—lacking the .com domain, poor search visibility, or trademark conflicts
- Names that customers find difficult to spell, pronounce, or remember
Sometimes companies need to modernise outdated brand identities or resolve trademark disputes. Whatever drives your decision, consider how the change affects your stakeholders and overall business strategy.
Choose a new name that meets legal rules
Your brilliant new company name might already be taken—or worse, it might violate UK naming laws. Getting this step wrong means starting over, so let’s make sure you pick a name that actually works.
Check name availability on Companies House
Start with the basics. Companies House offers a free name availability checker that tells you instantly whether your chosen name is available. This tool catches names that are identical or too similar to existing registered companies.
The “too similar” rule trips up many business owners. Names get rejected when they differ only by:
- Punctuation or special characters
- The words “and” and “&”
- Common abbreviations or plurals
- Minor spelling variations
Here’s a real example: if “Tech Spark Ltd” already exists, you probably can’t register “TechSpark UK Ltd” because of potential confusion. Companies House protects established businesses from copycats.
Avoid restricted or sensitive words
Some words require government approval before you can use them. These “sensitive words” fall into clear categories:
- Words suggesting special status (like “Association,” “British,” “Institute”)
- Terms linking you to UK government, devolved administrations, or the Royal Family
- Words for regulated activities (such as “Banking,” “Insurance”)
- Terms that could constitute criminal offenses
Companies House maintains the complete list in Annexe A, updated as of July 2024. Want “British” in your name? You’ll need approval from a prominent independent body proving your field prominence. Planning to use “Charity”? The relevant charity regulator must approve your request first.
Check for trademark conflicts
Here’s where many business owners make costly mistakes. Companies House registration doesn’t protect you from trademark disputes—that’s a separate legal issue entirely.
Choose a name too close to a registered trademark and you’ll face expensive legal challenges. Worse, you might be forced to rebrand completely. The UK Intellectual Property Office provides a trademark search tool to help spot potential problems.
Search beyond exact matches too. Check similar spellings, pronunciations, and related concepts. Planning international expansion? Search the European Union Intellectual Property Office and World Intellectual Property Organisation databases as well.
Decide between ‘Limited’ or ‘Ltd’
Most private companies must end their name with either “Limited” or “Ltd”—there’s no legal difference between them. Pick whichever looks better to you.
Your choice appears on your Companies House registration and incorporation certificate. After registration, though, you can use either version on business stationery and literature. Most companies choose “Ltd” during registration for simplicity.
The only exception: when filing documents with Companies House, use your registered name exactly as it appears on your certificate.
Some companies qualify for exemptions from using “Limited” or “Ltd.” This typically applies to companies limited by guarantee with articles promoting commerce, art, science, education, religion, or charity.
Pass the right resolution to approve the change
Your chosen name meets all the legal requirements. Now comes the formal approval process—and this is where many business owners get caught out by the paperwork requirements.
The Companies Act 2006 sets out specific procedures you must follow to make your name change official. Get this wrong, and you’ll face delays or rejection from Companies House.
Board resolution vs. shareholder resolution
You have two main routes to authorise your company name change. Shareholder approval through a special resolution needs at least 75% support. Alternatively, if your company’s Articles of Association explicitly allow it, the board of directors can approve the change through a board resolution.
Most companies start with directors meeting to discuss and approve the proposed name change. This initial approval then leads to seeking shareholder consent, unless your articles specify otherwise.
Check your company’s articles carefully. Standard articles usually require shareholder approval, but custom articles might allow directors to authorise a name change directly without shareholder involvement.
How to pass a special resolution
Special resolutions for company name changes need approval from shareholders representing at least 75% of voting rights. You can accomplish this in two ways:
At a general meeting – Provide at least 14 days’ notice to all members and directors. Your notice should include meeting details, the exact wording of the special resolution, and information about proxy rights.
Through a written resolution – Private companies can use this more convenient option, allowing members to vote without a meeting. The resolution must explicitly state it’s a special resolution and secure approval from at least 75% of eligible voting members.
Here’s a crucial point: when calculating the majority for special resolutions, you count shares with voting rights rather than the number of shareholders. If your company has 100 shares with one shareholder owning 60 shares and two others owning 20 each, the 60% shareholder effectively controls the decision.
Using Form NM01 or NM04
You must notify Companies House within 15 days after passing the resolution. The form depends on how your name change was approved:
- Form NM01 – Use when changing your company name by special resolution. Attach a copy of the resolution with your application.
- Form NM04 – Use when changing your company name through means provided in your articles of association (typically board resolution).
Form NM01 costs £20 online or £30 by post. Form NM04 must be submitted by post with a £30 fee.
Processing times vary significantly. Online applications typically complete within 24 hours, while postal applications may take up to 10 days. Need it faster? Same-day service costs £83.
Remember: your company name won’t officially change until Companies House registers it. You’ll then receive a Certificate of Incorporation on Change of Name as confirmation.
Submit the name change to Companies House
Your resolution is approved and forms are complete. Now comes the crucial step: getting Companies House to officially register your new company name. The submission method you choose will determine both your costs and how quickly you can start using your new identity.
Filing online vs. by post
Companies House has made online submissions the clear winner for most businesses. Nearly 90% of companies now file their name changes electronically, and it’s easy to see why. The online service handles changes made by special resolution only, which covers the majority of name change applications.
When you file online, you’ll complete the NM01 form electronically and upload a digital copy of your special resolution. The process is straightforward and gives you immediate confirmation of receipt. Postal submissions tell a different story entirely. You’ll need to download and print the appropriate form—NM01 for special resolution changes or NM04 for changes authorised by your articles of association. These paper forms must be posted to Companies House with a cheque for payment.
The choice seems obvious, but some businesses still prefer the traditional postal route, particularly for complex applications or when they need to submit Form NM04.
Fees and processing times
Your submission method directly affects both timing and cost:
- Online filing: £20 for standard service or £83 for same-day service
- Postal filing: £30 for standard service
Companies House processes most online applications within 24 hours, though they officially allow up to 48 hours. Same-day service provides extra peace of mind if you’re working to tight deadlines.
Postal submissions require significantly more patience. You’re looking at a week or longer for processing. This extended timeline means you’ll wait longer before you can officially begin operating under your new company name.
Receiving your Certificate of Incorporation on Change of Name
Companies House will issue your Certificate of Incorporation on Change of Name once they approve your application. This document serves as official proof of your name change and includes both your original and new company names, along with your unchanged company registration number.
Electronic filers receive their certificate digitally, while postal applicants get theirs by post. Keep this certificate at your registered office address or SAIL address if your company has one. While it doesn’t replace your original Certificate of Incorporation, it provides legal evidence that your company operates under its new name.
What to do after the name change is approved
Getting your Certificate of Incorporation on Change of Name feels like the finish line, but it’s actually just the starting gate. Your real work begins now—updating every aspect of your business to reflect your new identity.
Update HMRC and other authorities
HMRC needs to know about your name change immediately. This covers all your tax registrations: Corporation Tax, PAYE for employers, Self Assessment, and VAT. VAT registrations have a strict 30-day deadline, so don’t delay.
Different HMRC offices handle different taxes, which means separate notifications. Contact your Corporation Tax Office directly or call the Corporation Tax helpline. PAYE matters go through the HMRC employer helpline or the National Insurance Contributions and Employers Office.
Don’t forget your local council and other authorities—they need updates too to keep services running smoothly.
Change name on bank accounts and contracts
Your business bank accounts must match your official Companies House registration. Each bank has different procedures: some accept online or phone updates, while others want written instructions plus a certified copy of your Certificate of Incorporation on Change of Name.
Financial agreements, loans, and insurance policies all need updating to stay valid. Here’s a critical point many business owners miss: failing to notify your insurer could void your policy when you need it most.
Update website, email, and branding
You have 14 days to update all business stationery, signage, and websites. Your new company name must appear on:
- Website and email signatures
- Business letters, invoices and receipts
- Cheques and orders for money, goods or services
- Licence applications and all business correspondence
Set up email redirects from old addresses—you don’t want to lose important communications during the transition.
Notify customers, suppliers, and partners
Stakeholder communication separates successful name changes from chaotic ones. High-value clients deserve personal calls or meetings where you can explain the change and address any concerns. Suppliers need reassurance they’re still working with the same reliable company.
Create an internal communication plan for your team. Update their email signatures and business cards, and make sure everyone knows how to handle customer questions about the change.
Guide to changing your company name
Changing your company name doesn’t have to be overwhelming. Yes, there are legal steps to follow and paperwork to complete, but thousands of UK businesses successfully rebrand every year.
The process breaks down into manageable steps: check your eligibility, choose a compliant name, pass the right resolution, submit your application, and update your records. Most business owners find the hardest part is actually choosing the new name—not the legal procedures.
Your investment is modest too. At £20 for online filing, the cost is far less than most businesses spend on monthly software subscriptions. The real value comes from positioning your company for future growth and better market recognition.
The key to success? Don’t rush the process. Take time to research name availability thoroughly, ensure you have the required shareholder support, and plan your post-approval updates carefully. Business owners who prepare well avoid costly mistakes and complete their name changes smoothly.
Remember, your company name is more than just words on a certificate. It’s how customers find you, how suppliers recognise you, and how your team identifies with your mission. A well-executed name change can open new opportunities and help your business connect with the right audience.
Whether you’re rebranding to reflect growth, avoiding trademark issues, or simply modernising your image, you now have the knowledge to move forward confidently. Your new company name is just a few forms away.
