How To Change Your Company Name In The UK

Thinking about changing your company name? Whether you’re rebranding, pivoting to a new market, or simply want something that fits your business better, a company name change can be straightforward if you follow the right steps.

In this guide, we’ll walk through when and how you can change a limited company name in the UK, the legal rules to watch, and a clear step-by-step process to keep everything compliant and hassle-free.

Can You Change A Ltd Company Name? The Short Answer – Yes

Yes, a UK limited company can change its registered name. Under the Companies Act 2006, you can usually do this by a shareholder special resolution (75% approval), or via a built-in mechanism in your Articles of Association (if your Articles expressly allow directors to approve a name change).

Before you press go on a new name, make sure it actually meets the legal requirements. In particular:

• The name must be unique and not the “same as” another registered company’s name (or too similar in a way that confuses the public).
• Avoid restricted or “sensitive” words and expressions (for example, terms suggesting a connection with the government, the NHS or regulated professions) unless you have permission.
• Include the correct ending (Limited or Ltd), unless you qualify for and elect the permitted exemptions (for example, certain companies limited by guarantee).
• Consider whether you need Welsh-language endings if registered in Wales.

It’s also worth deciding whether you’re changing the legal company name or simply adopting a different trading name. A trading name (often called “trading as” or t/a) is different to your Companies House-registered name, and each path carries different legal and branding implications.

How To Change Your Company Name Step By Step

1) Decide The Scope: Legal Name Change Or Trading Name?

A legal name change is recorded at Companies House and affects all official documents. A trading name is largely a branding choice-you keep your legal name but trade publicly under a different name. If you only need a fresh brand signal, a trading name may be enough (and faster). If you want your legal identity to change (for contracts, regulatory registrations and cheques, etc.), go for a formal Companies House name change.

While you’re weighing options, think about brand protection. If this is a rebrand, check that you can secure a trade mark for the new name and related logos. This helps protect your brand against copycats once you’ve launched the new name.

2) Check Your Constitution And Owner Agreements

Your company’s Articles of Association may specify how a name change must be approved (for example, by directors, by a special resolution of shareholders, or by a particular process). Some bespoke Articles let directors approve a change; others default to shareholder approval.

If you have a Shareholders Agreement, check for any naming rights or consent thresholds around rebranding. It’s common to require supermajority consent or specific processes for material brand changes, so you’ll want to follow those rules to avoid disputes.

3) Pass The Correct Resolution

In most cases, you’ll need both a board meeting to approve the proposal (and the practical steps), and then a shareholder vote passing a special resolution (unless your Articles allow directors to approve the name change on their own). The resolution must clearly state the new name and the decision to adopt it.

For clarity on meeting process and records, it’s good governance to produce a properly drafted board minute and resolution. If you’re unsure, align your meeting and voting process with your Articles and the Companies Act requirements for a special resolution (75% approval) and keep formal records of the decision.

4) File The Change With Companies House

Once approved, file the name change online via Companies House (usually through WebFiling). You’ll either submit the notice of change of name by resolution or, where relevant, confirm the change by a means provided for in the Articles. A fee applies; check the current Companies House fee schedule and same-day options if timing is important.

Companies House will review and, if the name is accepted, issue a Certificate of Incorporation on Change of Name. This is your formal proof of the new legal name and the effective date.

5) Check The Effective Date And Update Your Records

Your new name legally takes effect from the date on the Certificate of Incorporation on Change of Name. From that date, you should begin using (and displaying) the new name in accordance with disclosure rules. Your registered special resolution and internal records should be filed and retained properly for your statutory books.

6) Tackle Your Rebrand Rollout And Compliance Checklist

After Companies House issues the certificate, systematically update your business identity everywhere relevant. The key areas usually include:

• Banking and finance: notify banks, lenders, payment processors and insurers.
• HMRC and other regulators: update VAT, PAYE, Corporation Tax, licensing authorities and any sector regulators.
• Contracts: review active agreements, supplier and customer contracts, leases and software licences. Depending on how parties are identified, some documents require formal updates or a side letter to avoid confusion.
• Digital presence: update your website, social media handles, email domains and app store listings.
• Public-facing materials: signage, packaging, marketing collateral and stationery.
• Internal systems: accounting software, CRMs, HR and payroll systems.

Where agreements name your old entity details, consider whether simple notices will suffice or whether formal changes are needed (for example, where the contract relies on an exact legal name). If in doubt, treat this as an opportunity to tidy your contract suite and ensure counterparties clearly recognise you under the new name.

7) Update Your Website Docs, Invoices And Legal Stationery

UK companies must display their registered name on business letters, order forms, websites and certain notices. You should also ensure your online terms and compliance documents reflect the new legal name and company details. In particular, refresh your Website Terms and Conditions and your Privacy Policy so they show the correct entity name, registered office, and company number. The same goes for your email footers, letterhead and invoices.

What Names Are Allowed? Companies House Rules To Know

Before you put a new brand on your shopfront, make sure it’s a legally usable company name. Companies House will generally reject names that:

• Are the same as, or essentially indistinguishable from, an existing registered name.
• Contain sensitive words or imply a connection to government or public authorities without permission.
• Are offensive or breach criminal law.
• Mislead the public about your activities or legal status (e.g., suggesting you’re an LLP or charity if you’re not).

You’ll also need the appropriate ending-Limited or Ltd (unless you qualify for and elect an exemption). If you’re rebranding for a UK-wide audience, consider how the name reads across the UK, any Welsh-language requirements (if relevant), and whether the domain and social handles are available.

Finally, company name approval does not equal brand clearance. A Companies House acceptance doesn’t give you exclusive rights to use the name as a trade mark. It’s smart to search and, ideally, protect your brand with a UK trade mark to secure the name (or your logo) for your goods and services.

Do You Need To Tell Customers, Suppliers And Regulators?

Yes. After the legal name change takes effect, you’re expected to update your disclosures and notify stakeholders so there’s no confusion around who they’re dealing with. Think through these areas as part of your rollout plan:

• Customers and suppliers: send a clear notice of name change and the effective date. Confirm that your registered office, company details and bank account identifiers are the same (or highlight any changes).
• Invoices and receipts: include the updated legal name and required details. If you use accounting software, adjust templates.
• Websites and emails: update the footer and contact pages to show the correct legal name, registered office and company registration details. Your Website Terms and Conditions and Privacy Policy should also reflect your new company name.
• Regulators and licences: notify HMRC (Corporation Tax, VAT, PAYE), update your details with the ICO (if registered for data protection fee), and inform any sector-specific regulators and local authorities (e.g., premises licence, professional registrations).
• Company registers and statutory books: record the resolution and retain the Certificate of Incorporation on Change of Name with your minute book and registers.
• Employment documentation: issue a short variation or covering letter to employees confirming the new employer name (the legal entity is the same-just the registered name has changed).

Common Pitfalls When Changing A Company Name

Not Checking Brand Clearance Early

It’s easy to fall in love with a new name only to discover someone already has a similar registered trade mark in your space. Conduct searches early and think about registering your own trade mark so your investment in the rebrand is protected long-term.

Overlooking Your Constitution And Owner Consents

Some companies find out late in the day that their Articles or investor agreements require consent thresholds or specific processes for rebranding. Reviewing your Articles of Association and any Shareholders Agreement up front will save time and avoid disputes.

Using The New Name Before It’s Official

Marketing teasers are fine, but avoid signing contracts or issuing invoices in the new name until your Companies House certificate is issued. Use the legal name that’s current on the public register to keep contracts clean and enforceable.

Forgetting To Update Legal Documents

Your rebrand is more than a new logo. Make sure your website, invoices, letterhead and contract templates are updated, and that active contracts correctly identify your entity after the change. Where appropriate, consider short amendment letters or updated templates so there’s no confusion for counterparties.

Leaving Stakeholder Communications Too Late

Banks, insurers, payment gateways and marketplaces can take time to process updates. Build in lead time and send consistent notices so cash flow isn’t disrupted and customers aren’t confused by unfamiliar billing names.

FAQs About Changing A Company Name

Do I Need A Special Resolution?

Usually, yes-unless your Articles specifically allow directors to approve a name change. A special resolution requires at least 75% shareholder approval. Record it properly and keep it with your company records.

Does My Company Number Change?

No. Your company is the same legal entity before and after the name change-your number, incorporation date and statutory history remain the same. Only the registered name changes (on the new certificate).

How Long Does It Take?

Online filings are typically processed quickly by Companies House, and there are same-day services for an additional fee. Plan your external comms and updates around the effective date on the certificate.

Can I Keep Using My Old Name As A Trading Name?

You can, but it’s usually better from a branding and clarity perspective to transition consistently. If you do use a trading name, ensure your registered name is still displayed where legally required (for example, on websites and invoices).
