How to Check if a Name Is Available for a Company

Picking a name for your new business is one of the most exciting parts of starting out. It also carries more legal weight than most people realise. Before you commit to a brand, print business cards, or build a website, you need to confirm that the name you have in mind is actually free to use. Knowing how to check if a name is available for a company is a fundamental step that protects you legally and prevents costly rebranding later.

The good news is that the process is straightforward and largely free. The UK has clear, accessible systems in place to help you verify name availability before you invest time and money into a business identity.

Can You Check if a Company Name Is Available in the UK?

Yes, absolutely, and you should do so before taking any other steps. Companies House maintains a publicly searchable register of every limited company incorporated in England, Wales, Scotland, and Northern Ireland. You can search this register directly at https://find-and-update.company-information.service.gov.uk/ at no cost, with no account required.

The search is case-insensitive and returns results for exact matches as well as similar names. This matters because Companies House will reject a new company name that is considered “the same as” an existing registered name, even if the spelling differs slightly. Punctuation, common words like “the” or “and,” and company suffixes like “Ltd” or “Limited” are typically disregarded when comparing names.

How to Check if a Company Name Is Still Available: Step by Step

The Companies House name search is the starting point, but a full availability check involves a few distinct layers. Type your proposed name into the Companies House register and review the results carefully, paying attention to names that are phonetically similar or visually close to yours. A name that passes the register search is not automatically cleared for use.

You should also search the UK Intellectual Property Office (IPO) trade mark database to confirm no one holds a registered trade mark for the same or a confusingly similar name in your industry sector. A company can exist under one name while holding a trade mark that prevents others from trading under a similar name, so checking both databases gives you a complete picture.

How to Check if a Name Is Taken for a Company: Beyond the Register

Passing the Companies House search does not mean a name is entirely clear. A business operating as a sole trader or partnership is not required to register with Companies House at all, yet that business may have built up significant reputation and goodwill under its trading name. Using an identical or near-identical name could still expose you to a legal claim under the law of passing off.

Searching Google thoroughly for your proposed name, combined with a trade mark check and a look at industry directories, gives you a much fuller picture. If you are setting up in a specific sector, checking relevant trade association member lists is also worth doing. The few extra minutes spent on these searches can save considerable legal expense further down the line.

MediumSimilar name used by a sole traderConsider rebranding or adding a distinguishing term
MediumMatching domain already ownedNegotiate purchase or adjust name
LowSimilar name in an unrelated industryProceed with caution and document your checks

According to Companies House guidance on company names, certain words and expressions also require special permission or supporting documentation before they can be used in a company name. Words such as “Royal,” “Chartered,” or “University” fall into this category and will be refused at the point of incorporation if the relevant approval has not been obtained.

Which AI Business Name Generator Actually Helps Before You Check Availability

AI business name generators have become genuinely useful as a brainstorming tool, and several have improved significantly in recent years. Tools such as Namelix, Looka, and Shopify’s free name generator can produce creative, domain-friendly suggestions based on your keywords and preferred style. They are particularly helpful when you are struggling to move beyond generic or taken names.

That said, no AI name generator checks the Companies House register or the UK IPO trade mark database in real time. They generate ideas, not legal clearances. The right way to use these tools is to generate a shortlist of candidates, then run each one through the official checks described above. Treating an AI suggestion as a cleared name without doing that verification is one of the most common mistakes new business owners make.

What Happens After You Confirm Your Company Name Is Available

Once you have confirmed that a name clears the Companies House register, the trade mark database, and any other relevant checks, you can move forward with confidence. Incorporating a limited company in the UK is done through Companies House, either directly via their online service or through a formation agent, and the process typically takes 24 hours or less when submitted online. The Companies House registration service walks you through each step of incorporation.

It is also worth registering your preferred domain name and social media handles at the same time as you secure the company name. The digital and legal identity of a business need to align, and leaving a gap between incorporation and domain registration occasionally gives others the opportunity to register the same domain. Acting on all fronts simultaneously protects your brand from the outset.

How to Check if a Name Is Available for a Company: What You Need to Know

Checking whether your chosen company name is available is not a single-step process; it is a layered due diligence exercise that covers the official register, trade mark law, common law reputation, and digital presence. Each layer addresses a different type of risk, and skipping any one of them can leave your business exposed. The Companies House register tells you whether the name can be legally incorporated, but it does not tell you whether using that name is commercially safe.

For anyone in the early stages of setting up a new business, the time invested in these checks is minimal compared to the cost of rebranding after the fact. Many sole traders and small company owners have discovered, sometimes expensively, that a name they believed was free turned out to carry an existing trade mark or an established business reputation that made continued use untenable. A proper check at the start is simply good practice.

Starting a business is one of the most significant decisions a person can make, and getting the name right matters. The official tools are free, accessible, and designed precisely for this purpose. Use them fully, document your searches, and if there is any genuine ambiguity around a name you love, a brief consultation with a trade mark solicitor will cost far less than a dispute further down the road.

  • Always check the Companies House register first, then the UK IPO trade mark database, then search Google and sector directories to cover both registered and unregistered name conflicts.
  • AI name generators are a useful brainstorming tool but do not perform legal clearance checks; treat their output as a shortlist to verify, not a confirmed availability result.
  • Securing your domain name and social media handles at the same time as incorporation protects your brand identity across all channels from day one.

How to Check if a Name Is Available for a Company: Frequently Asked Questions

What is the quickest way to check if a company name is available in the UK?

The fastest method is to use the free search tool on the Companies House website, which returns results instantly and requires no account or registration. You can access it at find-and-update.company-information.service.gov.uk and search by name or keyword.

Is the Companies House name search completely free?

Yes, searching the Companies House register is entirely free for anyone and does not require you to create an account. You can run as many searches as you need without any charge.

Can two companies have the same name in the UK?

No; Companies House will refuse to incorporate a company with a name that is considered the same as an existing registered name, even if spelling or punctuation differs slightly. Each registered company name must be sufficiently distinct from all others on the register.

Does passing the Companies House name check mean I can use the name freely?

Not necessarily, because a name may clear the register but still conflict with a registered trade mark or an established unregistered business trading under the same name. Always check the UK IPO trade mark database as a second step.

What is the UK IPO trade mark database and why should I check it?

The UK Intellectual Property Office maintains a searchable register of all registered trade marks in the UK, which you can search at ipo.gov.uk. Checking it ensures that no one has already protected your chosen name for use in the same type of business activity.

What does "same as" mean when Companies House compares names?

Companies House applies specific rules when assessing similarity, disregarding punctuation, common words such as "the" or "and," and company type suffixes such as "Ltd" when comparing names. For full details on how this works in practice, the Wikipedia entry on company name availability provides a useful overview of how naming conventions operate across different jurisdictions.

Can a sole trader prevent me from using a company name?

Yes, a sole trader or partnership that has built up reputation and goodwill under a name can bring a claim for passing off even without a registered trade mark. Searching for existing businesses trading under your chosen name is an important part of the availability check.

Do I need to check domain name availability separately?

Yes, domain availability is not linked to the Companies House register and must be checked independently through a domain registrar. A company name can be registered with Companies House even if the matching domain is already owned by someone else.

Which words are restricted in UK company names?

Certain words such as "Royal," "British," "University," and "Chartered" require special permission or supporting documentation from the relevant authority before Companies House will accept them. The full list is available in the Companies House guidance on incorporation and names.

How do AI business name generators work?

AI name generators use your keywords and style preferences to suggest available-sounding names, often with a bias towards short, memorable combinations that work as domain names. They do not check the Companies House register or trade mark database, so their suggestions must always be independently verified.

Can I reserve a company name before I incorporate?

There is no formal name reservation system through Companies House for standard incorporations; the name is only secured once your company is actually registered. The only way to hold a name is to incorporate the company, even if you do not intend to begin trading immediately.

What should I do if the company name I want is already taken?

Consider adding a distinctive word, a geographical reference, or an alternative descriptor to differentiate your name sufficiently. If the existing company appears to be dormant, you may also be able to contact its directors to discuss a voluntary name change or dissolution.

How long does it take to register a company name with Companies House?

Online applications submitted through the Companies House web filing service are typically processed within 24 hours, and many are completed within a few hours. Postal applications take considerably longer, usually between eight and ten working days.

Can I change my company name after registration?

Yes, a company can change its registered name at any time by passing a special resolution and filing the change with Companies House, subject to the usual name availability rules. The fee for a name change is currently £8 when filed online through Companies House.
