Choosing a name is one of the first (and most exciting) parts of starting your business.
It’s also one of the most important. The right name builds trust, stands out, and says something about who you are.
But your company name isn’t just a creative decision, it also has to meet Companies House rules.
Here’s how to choose a name that’s unique, compliant, and future-proof, explained simply.
Start with something that feels right
Your company name should reflect what you do, what you value, or how you want people to feel when they hear it.
It doesn’t need to be clever, it just needs to make sense.
A few pointers:
- Keep it short and easy to spell.
- Say it out loud, does it sound natural?
- Make sure it still works if your business grows or shifts focus later.
💡 Foundrs tip: A name that’s simple to pronounce and easy to remember will always outperform one that’s overly complicated or abstract.
Make sure it’s available
Before you get attached, check that your name isn’t already taken.
All UK company names must be unique on the Companies House register.
You can use the free search tool on the Companies House website, or (even better) let Foundrs check automatically while you type during setup.
If another company already uses a similar name, your application may be rejected.
It’s best to find this out now rather than later.
Avoid names that break the rules
Companies House has a few ground rules for what you can and can’t call your business.
Your name can’t:
- Be too similar to another registered company
- Contain offensive language
- Suggest a link to the government or local authority
- Include restricted words like Royal, Bank, or Accredited without permission
And if you’re registering a private limited company, your name must end with “Limited” or “Ltd”.
Foundrs automatically checks all these rules as you go, no memorising lists or fine print required.
Check for trademarks
Even if a company name is available on Companies House, someone might still own the trademark for it.
That means they’ve legally protected it for specific products or services.
You can search the UK Intellectual Property Office (UKIPO) database for free to make sure your name doesn’t clash with an existing trademark.
If your name is too similar to a registered brand, choose another one, it’s not worth the legal headache.
Think about your online presence
Once you’ve found a name you like, check the domain name and social handles.
Ideally, you’ll want them to match (or come close).
Consistency across your website, email, and social channels helps customers find you easily.
Even if you’re not ready to build a site yet, it’s worth buying the domain before someone else does.
Keep it simple for the long term
Trends come and go. Your company name might appear on contracts, invoices, and official documents for decades.
Pick something that will still make sense (and sound professional) years from now.
If you’re torn between a creative name and a clear one, go for clear.
You can always add creativity to your branding later.
Double-check before you register
Before you hit submit, review the essentials:
✅ The name is available on Companies House
✅ It meets all naming rules
✅ It’s not trademarked
✅ You’ve secured the domain and social handles
If you can tick all of those, you’re good to go.
With Foundrs, this entire process is built in.
Our setup automatically checks your name as you type, flags issues instantly, and confirms availability before you register, so you can move forward confidently.
In Summary
A good company name is clear, compliant, and feels like you.
It doesn’t have to be clever or complex, it just has to work.
Take a few minutes to check the basics, and you’ll save yourself time, cost, and frustration later.
Foundrs helps you get it right from the start, guiding you through every step of registration with no jargon, no guesswork, and no wasted effort.
