UK Business Name Availability: How to Check and Register Your Company Name

Picture this: Your company name is registered, but someone else owns the trademark. Sound familiar? Many UK business owners discover this costly lesson only after facing legal battles and expensive rebranding.

Your business name stands as your first handshake with potential clients. It’s your market identity, your brand foundation, and your memorable mark in your industry. Yet picking the perfect name requires more than creative thinking sessions.

The rules around business names might surprise you. Companies House registration, trademark checks, and specific legal requirements create a complex path toward securing your chosen name. One wrong step could mean starting the entire process again.

Ready to protect your business identity properly? This guide shows you how to check and register your UK company name the right way. You’ll learn the essential steps, common mistakes to avoid, and smart strategies to safeguard your brand from day one.

Understanding UK Business Name Types

Let’s clear up a common confusion about business names. Your business identity like a passport and a nickname – one’s official, the other’s casual. That’s exactly how company names and trading names work in the UK business world.

Your company name serves as your official identity at Companies House. It’s your business passport – legally protected and uniquely yours. Every private limited company must add ‘Limited’ or ‘Ltd’ to their name. Welsh companies can choose ‘Cyfyngedig’ or ‘Cyf’ instead 

Trading names work differently. They’re like business nicknames you use day-to-day. One company can have several trading names but here’s the catch – they don’t come with legal protection like registered company names do 

The rules don’t stop there. Using a trading name? You must show your registered company name and address on:

• Invoices and purchase orders
• Business letters
• License applications 

Watch out for these legal pitfalls with trading names:

• Stepping on trademark toes
• Looking too much like another business
• Using restricted words without permission 

Trading names do offer some smart advantages. You’ll only need to file paperwork under the registered company name, plus you can:

• Give different services distinct identities
• Grab matching online domains and social handles
• Run multiple ventures under one roof 

But before you jump in, remember these key limits:

1. Someone else could register your trading name as their company name
2. Without a trademark, others can freely use your trading name
3. No fancy terms allowed (like ‘limited’, ‘Ltd’, ‘LLP’, ‘plc’)

Want bulletproof protection? Consider registering your trading name as a trademark through the Intellectual Property Office. Yes, it means extra steps and costs, but it adds another layer of legal safety.

How to Check if Your Business Name is Available

“Is this name taken?” 

That’s your first question you should ask yourself  when naming your business. Let go through how to find the answer across four essential checkpoints. 

Your First Stop: Companies House Name Checker:

Start your search at Companies House, your official name-checking headquarters. Their free tool quickly spots identical or similar names that might block your registration. P your chosen name into their search box and study those results carefully. Remember – they’ll reject names that look or sound too much like existing ones.

Don’t Skip the Trademark Check 

Companies House approval isn’t enough. Head to the UK Intellectual Property Office (UKIPO) trademark database. This extra step could save you from trademark troubles later. Look for:

• Names matching yours exactly
• Similar names in your industry
• New trademark applications that might affect you.

Secure Your Online 

Home Your domain name matters just as much as your business name. Would your customers easily find you online? Search for available web addresses that match your business name. If your perfect .com or .co.uk isn’t available, consider alternatives that still reflect your brand’s personality.

Social Media: Your Digital Handshake 

Your social media presence needs to tell the same story. Before finalising your name:

• Check username availability on key platforms
• Try adding ‘the’ or your initials if needed
• Keep your handles consistent where possible

Use these four checks as your business name safety net. Each one protects your brand in different ways, working together to build your rock-solid business foundation.

UK Business Name Rules and Restrictions

Rules might sound boring, but they protect your business identity. The UK Companies Act 2006 sets clear boundaries for business names. Let’s break down these rules

The Building Blocks of Your Company Name 

Your registered company name needs ‘Limited’ or ‘Ltd’ at the end. Running your business in Wales? You can use ‘Cyfyngedig’ or ‘Cyf’ instead. Feel free to use standard keyboard characters plus special symbols like &, @, £, $, €, ¥, and #.

Red Flags and Warning Signs The Economic Crime and Corporate Transparency Act says no to names that:

• Open doors to fraud
• Include computer code
• Pretend to be government-linked

Some words need special permission. Want to use ‘Accredited’? You’ll need the Department for Business and Trade’s approval. Fancy something royal like ‘King’ or ‘Queen’? That requires special authorisation.

Playing the Name Game 

Companies House plays detective with your chosen name. They’re smart about it too. Adding dots, spaces, or symbols won’t make two identical names different. ‘Tech4U Ltd’ and ‘Tech4-U Ltd’? Sorry, they’re twins in the eyes of the law..

The Lookalike Rules

Here’s where it gets interesting. The ‘same as’ rule keeps the public from getting confused. But there are two potential exceptions.:

• You’re joining the existing company’s family
• The other company gives you their legal blessing. 

When comparing names, Companies House ignores these bits:

• Business tags (Ltd, PLC, LLP)
• Location markers (UK, Britain)
• Common business words (Co, Company)
• Punctuation marks and special characters 

Remember, these rules aren’t here to trip you up – they’re your guardrails for building a strong, legally sound business identity.

Registering Your Company Name with Companies House

You’ve picked your perfect name – now let’s make it officially yours. The registration process might seem daunting but let’s look at how to get your paperwork right the first time.

Your Registration Roadmap 

First things first – gather your company details. You’ll need your SIC code (that’s your Standard Industrial Classifier) which identifies the nature of your business. If you don’t have this, you can use Company House resources and information to work out which one is most appropriate.  

Next, choose your registered office address. Here’s a fact: it must be a real physical location, not just a PO Box.

Getting Your Papers in Order 

Here’s what you’ll need to include:

• Your company structure and chosen name
• Where official address
• Who’s running the show (director details)
• How your shares are set  up
• Who owns what (shareholder information

Don’t forget your company rulebook – the Memorandum and Articles of Association. Your initial shareholders need to sign these founding documents.

From May 1st 2024, the fee to register was increased significantly.:

• Digital applications: £50
• Postal applications: £71

Tip: If you do not want to use ‘Limited’ in your registered company name, you will need to make a postal application.

How long will you wait?

• Online: Your company could be registered within 24 hours 
• Postal:  around 8-10 working days

Success brings you a Certificate of Incorporation with your unique Company Registration Number (CRN). This eight-character code is your business passport – you’ll need it for:

• Keeping HMRC happy with annual accounts
• Getting your tax affairs sorted
• Talking to government bodies
• Sometimes for setting up your business account

One more thing – create a fresh Government Gateway ID just for your business for your registered business that’s separate from your personal one. 

Tip: Always keep your email address up to date – it’s Companies House’s hotline to you..

Conclusion

Your business name tells your company’s story before you speak a word. Through this guide, you’ve learned the crucial steps to make that story legally sound and professionally powerful.

Smart business owners know – protection comes from preparation. You’ve seen how company names differ from trading names, why each check matters, and what rules shape your choices. Each platform – Companies House, UKIPO, domain registrars, social media – adds another brick to your brand’s fortress.

Here’s what successful entrepreneurs understand: Companies House registration marks your beginning, not your endpoint. Ask yourself: Could trademark registration give your business extra protection, safeguarding your brand and growth? 

Time to prepare: Get your paperwork ready and double-check every detail against those naming rules. One small oversight could mean starting over – and paying twice.

Your business name carries your dreams, your reputation, and your future success. Take these steps seriously:

1. Research thoroughly
2. Verify meticulously
3. Register properly
4. Protect consistently

The extra time you spend today saves headaches tomorrow. Your careful choice and proper registration build the foundation for years of successful trading ahead.
