How To Change A Company Name In The UK: Step-By-Step Guide

Changing your company name can feel like a big moment - and in many ways, it is.

Maybe your original name no longer matches what you sell. Maybe you’ve pivoted, expanded, merged brands, or realised your current name is confusing customers (or too similar to someone else’s).

The good news is: in the UK, changing a company name is usually straightforward, especially for limited companies. The key is to follow the correct process, update the right records, and manage the “knock-on” legal and practical changes so your business stays protected from day one (and stays compliant as you grow).

This guide walks you through how to change a company name step-by-step, including what to do before you file anything, how the Companies House process works, and what you should update afterwards (contracts, invoices, website, HMRC, bank accounts, and more).

Can You Change A Company Name In The UK?

In most cases, yes - you can change a company name in the UK, including if you’re running a limited company (Ltd).

But the process depends on what type of business you’re running:

• Limited company (Ltd): you typically change the name by passing the required resolution (or following the approval route allowed by your articles) and filing the change with Companies House.
• Sole trader: you don’t change a “company name” at Companies House (because you’re not a company), but you can change your trading name and update HMRC/branding records.
• Partnership: the partnership can usually change the name under the partnership agreement (or by agreement between partners), and you’ll update your operational records and any registrations.

This article focuses mainly on the company name change process in the UK for limited companies, because that’s where there’s a formal filing process.

One quick reassurance: changing your company name doesn’t mean you’re creating a new company. Your:

• company number stays the same
• incorporation date stays the same
• existing contracts don’t automatically disappear (but you may need to manage the change properly)

Still, there are legal and commercial details you’ll want to handle carefully - especially if you have employees, customers on subscription terms, or supplier contracts in place.

Before You Change Your Company Name: Key Checks To Do First

If you’re thinking, “I want to change my company name - how do I do it?” start here. A bit of prep upfront can save you delays, rejected filings, and branding headaches.

1) Check The Name Is Available At Companies House

Companies House won’t register a new name if it’s the “same as” an existing registered name (or too similar under their rules). So, before you do anything else, search the proposed name on the Companies House register.

Also watch out for:

• names that are too similar to existing companies
• names with certain restricted words (for example, suggesting government affiliation or regulated activities)
• names that might trigger complaints under company names rules

Even if Companies House technically accepts the name, there can still be risks if another business has built up goodwill or trade mark rights in a similar name.

2) Consider Trade Marks And Brand Protection

Companies House registration is not the same thing as trade mark protection.

So if you’re rebranding because you want to grow, invest in marketing, or expand into new products, it’s smart to check whether your new brand name is already protected as a trade mark (and consider registering it yourself).

Trade mark strategy is a separate topic, but the main point is: your company name can be available while your brand name still creates legal risk.

3) Review Your Contracts And Business Documents

Your legal documents often refer to the company name in a very specific way (including “Ltd”, punctuation, and registered office address). The company number is also important.

Before you change the name, take stock of what will need updating, such as:

• customer terms and key client contracts
• supplier agreements
• loan or finance documentation
• shareholder arrangements
• employment documents

If you have investors or multiple owners, it’s also worth checking whether your Shareholders Agreement says anything about major business changes and decision-making processes.

And if you’re not sure what your company’s internal rules require for approvals, your Company Constitution (articles of association) will often set out how decisions must be made.

How To Change A Company Name (Limited Company): Step-By-Step

For an Ltd company, changing the name usually has two main parts:

• getting the right approval internally (often a resolution)
• filing the change with Companies House

Here’s the step-by-step process most small businesses follow.

Step 1: Decide How You’ll Approve The Name Change

In many cases, a company name change requires shareholder approval (not just directors), because it’s a fundamental company change.

However, some companies can approve a name change using a directors’ resolution if their articles of association allow it. So it’s important to check your articles (and any shareholders’ agreement) before you decide the approval route.

You’ll typically approve it by:

• Special resolution (commonly used): requires a 75% majority of shareholders who vote (subject to your articles)
• Written resolution: shareholders sign to approve without holding a meeting
• Resolution at a meeting: shareholders vote at a general meeting

Exactly what you need depends on your articles of association and share structure.

It’s worth documenting things properly, especially if there are multiple shareholders or any chance of disputes later. Many companies also keep meeting minutes and resolutions with their company records to show the decision was validly made.

Step 2: Check If Any Consents Or Notifications Are Needed

This step gets missed a lot.

Before you file the new name, consider whether you need to notify or get consent from:

• your bank or finance provider (some facilities require notification of changes)
• key customers (especially enterprise clients with strict onboarding requirements)
• your landlord (if you have a commercial lease)
• regulators (if you’re in a regulated sector)

This isn’t always a legal requirement, but it can be a contractual requirement. A quick review of your key agreements now can prevent a “breach by accident” later.

Step 3: File The Name Change With Companies House

Once the company has validly approved the change, you file it with Companies House.

Most companies do this online via Companies House (it’s often faster). You can also file using form NM01 (paper filing), depending on your situation.

You’ll typically need details such as:

• your company number
• the proposed new company name
• confirmation of the resolution/approval

After Companies House accepts it, they’ll issue an updated certificate of incorporation showing the new name.

Timing can vary, but online filings are often processed faster than paper filings.

Step 4: Update Your Statutory Registers And Company Records

Even after Companies House updates the public register, you should also update your internal records and templates, such as:

• company records (for example, where you store resolutions and key corporate documents)
• company letterhead templates and formal documents
• any share certificate templates (if your templates reference the company name)

In most cases, your statutory registers (members, directors, PSCs) don’t need “amending” just because the company’s name changes, but it’s still worth checking your records are consistent and up to date across your corporate documents.

This is one of those “admin” steps that still matters. If you ever go through due diligence, investment, or a business sale, clean company records can save a lot of time and cost.

What To Update After A Company Name Change (So You Stay Compliant)

Once your new name is registered, you’re not quite done.

From a legal and compliance perspective, the risk isn’t usually the Companies House filing - it’s the aftercare. In other words: making sure you don’t keep trading under a new name while leaving old details on key documents and systems.

1) HMRC, VAT, PAYE And Payroll

If you’re registered for VAT, PAYE, or Corporation Tax, you’ll generally need to make sure HMRC records are updated so your filings match your registered company name.

If you’re running payroll, you’ll also want payslips and payroll software to reflect the correct employer name.

Note: this is general information only and isn’t tax advice. If you’re unsure how the change affects your HMRC registrations or filings, it’s worth checking with your accountant or a tax adviser.

2) Bank Accounts, Payment Providers And Insurance

Most banks will require supporting evidence (often the updated certificate of incorporation) to change the name on accounts.

Also consider:

• payment processors (so customer receipts show the right legal entity name)
• insurers (so your cover is clearly tied to the correct legal entity)
• loan agreements and finance documents

This is especially important if you’re making large transactions or handling client money, because mismatched names can trigger delays or compliance checks.

3) Contracts, Terms And Invoices

Your existing contracts don’t automatically become invalid just because your company name changes - the legal entity is the same company number.

That said, in practice you should handle this carefully. You may want to:

• send a simple notice to customers/suppliers confirming the name change (and the effective date)
• update template agreements going forward
• consider a short deed/variation for major contracts where clarity is critical

If you use standard customer terms, update them promptly so your legal entity details are correct. If you sell online and collect personal data, it’s also a good time to update your Privacy Policy so it reflects the correct controller name and company details.

Also update invoices and receipts - many small businesses overlook this, but a correct legal name, address and company details help with professionalism and reduce disputes (especially in B2B relationships).

4) Your Website, Email Signatures And Business Stationery

UK companies have disclosure rules about what they must show on business communications (for example, on websites and emails). So once you change your name, update:

• website footer (company name, registration number, registered office address)
• email signatures for directors/staff
• quotes, proposals and letterheads
• customer-facing documents (order confirmations, T&Cs, onboarding forms)

This isn’t about being “perfect” - it’s about being consistent and reducing the risk of confusion about who the customer is contracting with.

5) Employment Documents And Workplace Policies

If you have employees, you’ll want to update the employer name in:

• employment contracts
• staff handbook/policies
• HR letters and templates

For new starters, make sure your Employment Contract template shows the updated company name, registration number (where used), and address.

If you’re making broader changes during a rebrand (new group structure, new roles, new reporting lines), it’s worth checking that your documents still match how the business operates in practice.

Common Mistakes When Changing A Ltd Company Name (And How To Avoid Them)

Changing a company name is usually manageable - but these are the issues we commonly see when businesses do it quickly without a plan.

Forgetting The Difference Between A Company Name And A Trading Name

Your registered company name is what appears on Companies House. Your trading name is what you use in the market (which can be different).

You can trade under a different name without changing your registered company name - but you still need to disclose your registered details correctly in many contexts, and you should avoid misleading customers about who they’re dealing with.

If you’re changing your registered name specifically to match your brand, that’s usually a good “tidying up” move - just do it properly.

Not Updating Customer-Facing Terms And Subscription Arrangements

If you have ongoing customer relationships - retainers, subscriptions, auto-renewing plans - make sure your paperwork and notices reflect the new name.

As a general rule: if your customers can cancel or renew, or if you change pricing or key terms, you’ll want your documentation to be clear and up to date. A rebrand is a good moment to sanity-check your Subscription Terms as well.

Not Checking Whether The New Name Creates IP Or Reputation Risk

Even if Companies House approves the new name, another business may still challenge it if they believe it’s too close to their name or brand.

If you’re putting real money into the new brand, it’s often worth doing a trade mark check and a broader brand risk review.

Assuming You Need A New Company Or New Contracts

Many business owners worry that a company name change means they must re-sign every contract from scratch.

Usually you don’t need to do that - but you do need to manage the transition clearly so customers and suppliers aren’t confused.

In some cases, a short contract variation or formal notice is the cleanest option (particularly for high-value contracts, regulated clients, or finance agreements).

Key Takeaways

• In most cases, you can change a company name in the UK, including if you run a limited company (Ltd).
• For an Ltd, the usual process involves approving the change (often by shareholder resolution, or sometimes by directors if the articles allow) and then filing the change with Companies House.
• Before you file, check the name is available and think about brand and trade mark risk, not just Companies House acceptance.
• After your company name change, make sure you update key business records like HMRC registrations (where relevant), bank accounts, insurance, invoices, website disclosures, contracts, and employee documents.
• Your company number stays the same, and contracts often continue - but you should still handle the change carefully to avoid confusion and contractual issues.
• If you have multiple owners, make sure the decision-making process matches your articles/shareholder arrangements and your company records are properly documented.
