Can Someone Use My Brand if I don’t Trademark It?

The uncomfortable answer is quite possibly, yes. An unregistered brand is not unprotected in the UK, but the protection it has is the kind you must build a case for, while a registered trademark is the kind you can simply point to. That difference decides how most brand disputes actually end.

The right you fall back on: passing off

Trade under a name without registering it and your protection comes from passing off, a right built by the courts rather than the register. To stop a rival you must prove three things: that you have goodwill in the brand, a trading reputation customers actually associate with you; that the rival’s use misrepresents their goods or services as yours, or as connected with you; and that the misrepresentation causes you damage. Each element takes evidence. Goodwill means sales figures, advertising spend, customer declarations, press coverage, assembled over the period you have traded.

That evidential weight is the problem, and it lands hardest on the businesses that most need protecting. A brand two years old with a modest customer base may have real momentum and thin goodwill in the legal sense. Passing off also protects the reputation you have built rather than the name as such, so it tends to be local to the markets where you have traded and can struggle against use in a different sector or city. It is a real right, and businesses do win with it, but it is slow, expensive and uncertain in exactly the situations where a young brand needs speed.

What registration changes

A registered trademark inverts the position. Registration under the Trade Marks Act 1994 gives you a statutory right in the mark itself, from the date of registration, for the goods and services covered. To act against an infringer you point to the registration. There is no need to prove years of trading history first, and the registration works before you have much history to prove. It also deters quietly as your mark sits on the public register, where anyone clearing a new name, or their professional, will find it and route around it.

The cost is modest against what it replaces. As at July 2026 an online UK application is £205 including one class of goods or services, plus £60 for each further class. The registration lasts ten years and can be renewed indefinitely for further ten-year periods, so protection continues for as long as the brand does.

The register does not wait for you

Here is the risk that surprises unregistered brand owners most. If someone else applies to register a name similar to yours, the UK Intellectual Property Office (UKIPO) will not refuse them because you were trading first. Since 2007 the registry has not blocked applications over earlier conflicting rights. It notifies the owners of earlier registered marks it finds and leaves objections to them. With no registration, you are not even on the list to be told. Your first notice may be a letter from the new owner of “your” name.

You could oppose their application, and prior goodwill protectable by passing off is a recognised ground, but you would be back to proving goodwill on evidence, this time to a deadline (see our guide on what happens if someone opposes your trademark). Lose the race to the register and the practical options narrow to challenging their mark, negotiating, or rebranding, and none of the three is cheap.

Acting early, and in the right order

The habits that avoid all of this are inexpensive. Businesses commonly search the register before committing to a name, so the marketing budget is not spent decorating somebody else’s mark. Registration tends to come before heavy brand spending rather than after, for the same reason. And because trademarks are territorial, a UK registration protects you in the UK only; businesses selling abroad usually extend protection to their main markets as they grow (our guide on the Madrid Protocol explains the usual route). Where money is tight, the trademark is generally the first registration worth buying, a sequencing question our guide on building an IP portfolio on a startup budget works through.

Two questions that come up

Do I have any rights at all if I never register? Some. Passing off can protect an unregistered brand with established goodwill, and you may use the ™ symbol on an unregistered mark (the ® symbol is only for registered ones). But the rights are harder, slower and more expensive to enforce, and they may not exist at all where goodwill is thin.

What if a competitor registers my brand name first? You may find yourself unable to register without first challenging their mark, through opposition if you catch the application in time or invalidation if you do not, and both routes put the evidential burden on you. In the worst case the practical answer is a rebrand. Registering early is the cheap way never to have this conversation.
