Common Problems When You Register a Business Name

Even with careful planning, you might encounter issues during business name registration. Knowing these common problems can help you resolve them quickly.

Name Rejected by Companies House

If you're registering a limited company, your chosen name might be rejected if it's too similar to an existing name on the Companies House register, contains sensitive words without permission, or is deemed offensive. The Companies House system has strict rules on what constitutes "too similar" – even small differences in punctuation or a single letter might not be enough.

Fix: Always have a few backup names ready. If your first choice is rejected, try your second or third option. Review the Companies House naming rules carefully to understand why your name was rejected and adjust accordingly. You can use their online tool to check for similar names before submitting.

Name Too Similar to an Existing Business (Sole Trader/Partnership)

While sole traders and partnerships don't formally register their trading names with Companies House, choosing a name that is too similar to an existing business can still cause problems. This can lead to customer confusion, damage your reputation, and potentially result in legal action if the other business has a trademark or can prove you are 'passing off' as them.

Fix: Thoroughly search Companies House, the UK IPO trademark register, and online search engines before you start trading. If you find a similar name, choose a more distinct one. Consider consulting a legal professional if you're unsure about the similarity.

Trademark Infringement Claims

One of the most serious problems is using a business name that infringes on an existing trademark. A company that has trademarked a name, logo, or slogan can take legal action against you if they believe your use of a similar name causes confusion or damages their brand. This can result in costly legal fees, fines, and being forced to change your business name and branding.

Fix: The best defence is prevention. Always conduct a thorough search of the UK Intellectual Property Office (IPO) trademark register (www.gov.uk/search-for-trademark) before finalising your name. If you find a similar trademark, either choose a different name or seek legal advice to understand the risks.

Domain Name or Social Media Handles Unavailable

You've picked the perfect business name, but then discover that the corresponding website domain name or social media handles are already taken. This can be frustrating and make it harder for customers to find you online.

Fix: During your initial brainstorming and checking phase, verify domain and social media availability alongside Companies House and trademark searches. If your exact name isn't available, consider slight variations, adding a geographical indicator (e.g., "YourNameLondon"), or using an alternative domain extension (.co.uk if .com is taken, or vice versa).

Sensitive Words Requiring Permission

Certain words, like "Bank," "Royal," "Chartered," "NHS," or implying a connection with government, require special permission to be used in a limited company name. Using them without permission will lead to rejection of your application by Companies House.

Fix: Before you incorporate, check the full list of sensitive words and their specific requirements on the Companies House website. If you wish to use one, ensure you have obtained the necessary permission from the relevant body before submitting your application. Often, it's simpler to choose a name that doesn't include sensitive words.

Advanced Tips for How To Business Name Registration

Beyond the basic registration steps, there are ways to strengthen your business name and brand identity.

Consider Trademarking Your Business Name

For limited companies, while your name is registered with Companies House, this only prevents others from registering an identical or too-similar limited company name. It does not provide broader protection against others using a similar name for a different type of business or product. If your business name is crucial to your brand and you want to prevent others from using it, consider applying for a trademark with the UK Intellectual Property Office (IPO).

A trademark gives you exclusive rights to use your name (or logo) for specific goods and services across the UK, allowing you to take legal action against infringement. This is a significant investment but offers strong legal protection for your brand.

Think Long-Term and for Brand Scalability

When choosing a name, try to think about your business's future growth. Will the name still be relevant if you expand into new products, services, or geographical areas? A name that is too narrow or restrictive might require a costly rebrand down the line. For example, "City Centre Coffee Shop" might not work if you open a second branch outside the city centre or start selling baked goods online.

Opt for names that are versatile, memorable, and can accommodate future expansion without sounding out of place.

Get Professional Advice for Complex Cases

If your business involves a complex name, sensitive words, or you're operating in an industry where naming disputes are common, it's wise to consult with a legal professional specializing in intellectual property or corporate law. They can help you navigate the nuances of trademark law, assess potential risks, and ensure your chosen name is robustly protected.

Similarly, an accountant can provide guidance on the best business structure for your needs, which in turn influences your naming and registration obligations.

Protect Your Brand's Online Reputation

Beyond securing domain names and social media handles, actively monitor your business name online. Set up Google Alerts for your business name to be notified if it's mentioned. This helps you keep track of your brand's reputation and quickly address any potential misuse of your name by others.

Engage with your audience on social media and maintain a professional online presence to reinforce your brand identity and distinguish yourself from any similarly named entities.

How To Business Name Registration FAQ

Do I need to register my business name if I'm a sole trader?

As a sole trader in the UK, you don't 'register' a business name with Companies House in the same way a limited company does. You register yourself as self-employed with HMRC. You can trade under your own name or choose a business name, provided it's not offensive, doesn't imply connection to government, or infringe on existing trademarks. If you use a business name other than your own surname, you must still include your personal name and business address on official documents.

Can two companies have the same name in the UK?

For limited companies, Companies House will generally not allow two companies to register names that are identical or "too similar." There are strict rules to prevent confusion. However, it is possible for a sole trader or partnership to use a trading name that is similar to an existing limited company name, which can lead to confusion or legal issues if a trademark exists. This highlights the importance of checking both Companies House and the UK IPO trademark register.

How much does it cost to register a business name?

If you're setting up a limited company and registering its name directly with Companies House online, the fee is typically around £12-£15. If you use a company formation agent, the cost will be higher but often includes additional services. For sole traders and partnerships, there is no direct fee for 'registering' a business name, as you register as self-employed with HMRC, which does not incur a fee for registration itself.

How long does business name registration take?

Registering a limited company name with Companies House online usually takes less than 24 hours, often within a few hours, if all information is correct and the name is accepted. Registering as self-employed with HMRC is also a quick online process, typically taking a few minutes to complete the form, though it can take a few weeks for HMRC to process and send you your Unique Taxpayer Reference (UTR).

What if my chosen name is taken or rejected?

If your chosen name is already taken or rejected, you will need to choose an alternative. It's highly recommended to have several backup names prepared before you start the registration process. If a limited company name is rejected by Companies House, they will explain why, allowing you to choose another name that complies with their rules. If a name is trademarked, you absolutely must choose a different name to avoid legal action.

Can I change my business name later?

Yes, you can change your business name later, but the process varies by business structure. For a limited company, you must pass a special resolution by shareholders and inform Companies House, which involves a formal procedure and sometimes a fee. For sole traders or partnerships, changing a trading name is simpler, but you should update any official documents, websites, and inform HMRC if your trading name is prominent in your self-assessment records or business communications.
