Business challenging trading name

Hello, I am Gemma, your friendly legal assistant at Lawyer Destroyer. I can certainly help you understand the rules around trading names in England and Wales.

The short answer is yes, another business can potentially force you to stop using your trading name, but only if they have the legal right to do so. This usually comes down to who used the name first, what they have registered, and whether the names are similar enough to confuse the public.

The legal position:

There are two main ways another business could try to stop you.

The first is through a registered trademark. If the other business has already registered your trading name, or a very similar name, as a trademark in the UK for the same types of goods or services you provide, they have a strong legal right to stop you using it. Doing so is known as trademark infringement.

The second way is through an older, unregistered legal right called passing off. Even if the other business has not registered a trademark, they might be able to stop you if they have built up a strong, established reputation using that name. To succeed in a passing off claim, they must prove three things. First, that they have an established reputation in the name. Second, that your use of the name is confusing customers into thinking your business is connected to theirs. Third, that this confusion is financially damaging their business.

A common misunderstanding:

Many people think that because they have safely registered their company name at Companies House, they have an absolute right to publicly trade under that name. Unfortunately, this is not true. Companies House registration simply creates a corporate entity. It does not automatically grant you intellectual property rights, and it does not give you permission to accidentally trample on someone else's existing trademark.

Practical next steps:

If another business has formally contacted you, perhaps with a cease and desist letter, it is important not to panic. Taking these disputes all the way to a formal court trial is incredibly expensive, risky, and stressful for both sides. Because of this, these matters are very often settled informally out of court.

1. Gather the facts. Check exactly what the other business does and where they are based. If you are a local bakery in Cornwall and they are a corporate IT firm in Yorkshire, you are not competing for the same customers. In that scenario, legal action is very unlikely to succeed because there is almost no risk of public confusion.

2. Look at the trademark register. You can do a free search on the Intellectual Property Office website to see if the other business actually owns a registered UK trademark. If they do, look closely at the date they registered it and the specific categories of goods or services they are protected for.

3. Build your timeline. Work out the exact date you first started trading under your name. Gather evidence to prove this, such as your very first client invoices, archived copies of your website, or early marketing materials. Prior use is very important. If you were genuinely trading before they registered their trademark or set up their business, you might actually have the stronger legal position.

4. Think about the commercial reality. If you discover that they clearly used the name first, are in your exact industry, and hold a registered trademark, the smartest business decision might be to rebrand. It is deeply frustrating, but negotiating a grace period to change your name is almost always cheaper than fighting a losing intellectual property battle in court.

5. Try to find a sensible compromise. If the situation is a bit grey, with neither side having a perfect run at the name, you might be able to suggest a co-existence agreement. This is where you both agree to respectfully keep using your names, perhaps by promising never to expand into each other's specific geographical territory or product range.

What you should do next depends entirely on the exact timeline of events, what is on the trademark register, and how similar your two businesses genuinely are. Work out those facts first, and that will guide how you should reply to them.
