Before you can register your company with Companies House, you need a name that meets very specific legal criteria. It can’t be too similar to an existing company, it must avoid restricted words, and it has to comply with strict formatting rules. Miss any of these, and your application will be rejected.
Over 560 applications were rejected in 2024 alone because the names could offend or potentially break the law, up from 479 in 2023. These are not trivial errors but unnecessary obstacles that can delay your launch and derail marketing plans.
This guide walks you through how to choose a name that Companies House will accept, avoid delays, and position your business with a strong legal and brand foundation from day one.
How to Choose the Right Company Name for Companies House Registration
1. Understand Companies House Naming Rules
Before you commit to a company name, it must pass Companies House’s legal checks. These rules are strict and apply to every business registering in the UK. Here’s what to look out for:
Prohibited and Sensitive Words
Certain words and expressions are either restricted or outright banned. You’ll need special permission or supporting documents if your name includes:
- Words suggesting government status, e.g. “Authority”, “Commission”, or “Board”
- Regulated terms like “Bank”, “Charity”, “Solicitor”, or “Architect”
- Words that imply national importance, such as “British”, “Royal”, or “International”
Using these without approval will result in your application being rejected. For full guidance, refer to the official list of sensitive words and expressions.
Check for Name Availability
You can’t register a name that’s identical or too similar to an existing company. Even small differences, like punctuation, plurals, or common descriptors like “UK” or “Group”, often aren’t enough to make it distinct.
Use the official Companies House name checker to verify your proposed name before moving forward.
Other Legal Restrictions
- Your company name must end with “Limited” or “Ltd”, unless exempt (e.g. a charity or community interest company).
- Offensive or misleading names will be rejected.
- The core name must use characters from the Roman alphabet (Welsh names may include specific Welsh characters).
Skipping these checks can lead to delays or rejections, both of which are easily avoidable if you handle this step properly.
2. Make It Unique and Memorable
A name that sounds generic or too similar to others won’t just risk rejection, it’ll also be forgettable. Distinctiveness is key, both for legal approval and brand recognition.
Avoid names that blend in with competitors or rely on overused industry terms. “Tech Solutions Ltd” or “Global Traders Ltd” may sound professional, but they’re unlikely to stand out and likely already exist in some form.
Keep it simple, pronounceable, and easy to spell. Complicated or obscure names create barriers for customers and increase the chance of errors on official documents.
When brainstorming, aim for a name that’s short, recognisable, and adaptable. If you can explain it in one sentence and remember it the next day, you’re on the right track.
3. Think Long-Term: Scalability and Versatility
Your company name shouldn’t box you in. While it might be tempting to include a specific service or location in your name (like “Leeds Plumbing Experts Ltd” or “UK Vegan Snacks Ltd”), this can become a problem if you expand into new markets or offer additional services later.
Instead, choose a name that gives you room to grow. If you plan to diversify or scale, avoid overly descriptive or niche wording that could feel outdated in a year or two.
Also consider how the name works across different contexts, for example, will it still make sense if you expand internationally or into a digital-first space?
Think of your name as a long-term asset, not a temporary label. A scalable name protects you from rebranding costs and confusion down the line.
4. Consider Domain Availability and Digital Presence
In today’s business world, your online presence starts with your domain name. Even if your company name ticks all the legal boxes, if the matching domain is already taken or worse, used by a competitor, you could face branding headaches.
Before settling on a company name, check if the exact domain (especially the .co.uk and .com versions) is available. Tools like GoDaddy or Namecheap make this quick and easy.
Also, don’t forget social media handles. Consistency across platforms like Twitter, Instagram and LinkedIn builds brand recognition and prevents confusion.
If your ideal domain isn’t free, consider slight variations but avoid complicated or lengthy URLs. A simple, memorable web address aligned with your company name boosts credibility and helps customers find you fast.
5. Align With Your Brand Identity
Your company name should reflect what your business stands for and who you want to attract. It’s more than just a label, it’s the foundation of your brand’s personality.
Think about the tone you want to set. Is your business professional and formal, or casual and approachable? For example, a financial services firm might want a strong, trustworthy name, while a creative agency might choose something playful or innovative.
Also, consider your target audience. The name should resonate with them and give a clear sense of your mission or values without needing a long explanation.
Consistency matters too. Your company name should fit seamlessly with your logo, marketing materials, and website to create a cohesive brand experience that sticks in people’s minds.
6. Check for Trademarks and Intellectual Property Conflicts
Choosing a company name that’s legally available at Companies House is just one part of the puzzle. You also need to make sure it doesn’t infringe on existing trademarks. Using a name that’s already trademarked can lead to costly legal disputes and force you to rebrand later.
Start by searching the UK Intellectual Property Office’s trademark database to see if your proposed name, or something similar, is already registered in your business category.
If you find a conflict, it’s best to rethink your name now rather than face objections after registration.
If your name is clear, consider registering it as a trademark yourself. This protects your brand and prevents competitors from using a similar name or logo.
Taking these steps early safeguards your business and strengthens your legal position from day one.
7. Get Feedback Before Finalising
Before you lock in your company name, get input from people who matter, your target audience, colleagues, or industry peers. What sounds good to you might be confusing or off-putting to others.
Testing your name helps uncover potential issues like awkward pronunciations, unintended meanings, or cultural sensitivities you might have missed. This is especially important if you plan to operate internationally, where words can carry very different connotations.
Ask straightforward questions: Is the name easy to remember? Does it convey the right message? Would they trust a company with that name?
Gathering honest feedback early saves you from costly rebranding or legal headaches down the line. It also gives you confidence that your name resonates beyond your own perspective.
8. Secure the Name with Companies House
Once you have chosen a name that meets all legal requirements and passed your own checks, the next step is to officially register it with Companies House. This is the only way to secure the name for your company and prevent others from using it.
You can register your company and name online through the Companies House website. The process is straightforward but requires careful completion to avoid delays or rejections.
If the name you choose is rejected, Companies House will provide a reason. Common reasons include similarity to an existing company, use of restricted words without permission, or names deemed offensive or misleading.
If rejected, you can submit a new name or appeal if you believe the decision was in error. It’s a good idea to have several backup names ready at this stage.
Registering your company name officially protects your brand and sets your business up for success from day one.
