If your business name matters to you, it’s usually worth trademarking — and registering your company at Companies House does not do it for you. A registered trademark gives you the exclusive right to that name for your goods or services across the UK, and the right to stop copycats without first proving years of reputation. It costs £205 to file online for one class.
It’s not a legal requirement, and it isn’t always urgent. But the trap catches people who assume they’re already protected. You are not protected just because you’ve registered a company, bought the domain, or used the name for years. Here’s how to decide — and what to check first.
What trademarking your name actually does
A registered trademark gives you:
- Exclusive rights to your name for the goods or services you registered, anywhere in the UK.
- The right to sue for infringement — without first having to prove you’ve built up a reputation (which an unregistered name always requires).
- A deterrent. Competitors and their advisers search the register before they name things; a registration on record is what they find — and it often turns them away.
- A business asset that adds value when you raise money, license your brand, or sell.
What it does not give you: protection outside your registered classes, protection in countries where you haven’t filed, or any monopoly on ordinary descriptive words.
The three things people confuse with protection
This is where most of the risk hides.
Companies House ≠ trademark. You can own “Bloom & Co Ltd” at Companies House and still have someone else register “Bloom & Co” as a trademark and enforce it against you. Company registration gives you no trademark rights, and the IPO doesn’t check Companies House when it examines a mark.
- A domain isn’t protection either. Owning the .co.uk gives you an address, not a brand right — and a later trademark owner can challenge the domain.
- “I’ve used it for years” is the weakest position. Unregistered names rely on passing off, which means proving three things in court: established goodwill, that someone misrepresented their goods as yours, and resulting damage. It’s slow, expensive and uncertain. A registration replaces all of that with a single right.
When it’s worth doing now
Register sooner rather than later if:
- You’re investing in the name — marketing, packaging, a product launch.
- The name is distinctive (invented or arbitrary), so it’s straightforward to protect.
- You’re raising money or might sell — investors and buyers expect the brand to be owned.
- You operate online or nationally, where conflicts surface fast.
When it’s reasonable to wait (but still check)
- You haven’t settled on the final name.
- You’re running a quick, low-spend pilot.
- The name might be too descriptive to register — worth confirming before you invest in it.
Even if you wait to register, check the name now. Discovering a conflict after you’ve printed packaging or built a following is the expensive way to find out.

Check a name free →What you can (and can’t) register
You can register names, words, logos, slogans, and more — as long as the mark is distinctive. You generally can’t register:
- Purely descriptive names (“Cheap Flights”).
- Generic or common industry terms.
- Marks that are misleading, offensive, or too similar to an existing registered mark in the same field.
A quick test: the more your name describes what you sell, the harder it is to protect; the more invented it is, the easier.
Sole traders and freelancers
You don’t need to be a limited company. A sole trader can register a trademark in their own name and assign it to a company later. If you’re building a personal or service brand under a trading name, a registration is often the single most valuable bit of protection you can buy for £205.
So — should you?
If the name is central to your business and reasonably distinctive, yes — and the smartest first move costs nothing: search the register before you spend a penny on filing. If it’s clear, registering is straightforward. If it’s not, you’ve just saved yourself a non-refundable fee and a rebrand.
