Register a Trading Name in the UK
Choosing how your UK business presents itself is one of the first branding decisions an overseas company makes when setting up here, and it often gets tangled up with the legal process of incorporation. The two are related but not the same thing, and mixing them up leads to a common misunderstanding: that a trading name needs to be formally registered somewhere, the way a company name does.
It doesn’t. A trading name is simply the public-facing name your business operates under, and it can differ freely from the name registered at Companies House. What does need attention is a smaller set of rules around disclosure, trademark risk, and making sure your registered company details still appear correctly wherever you’re doing business.
This guide sets out the actual distinction, what’s legally required once you’re trading under a different name, and where overseas businesses most often get it wrong.
What Is a Trading Name, and How It Differs From a Company Name
Your company name is the legal identity of your business, chosen and approved during incorporation, and recorded permanently on the public register at Companies House. It’s protected by law: no other UK company can register an identical or near-identical name once yours is taken.
A trading name is different. It’s the name customers, suppliers, and the public actually see, used on your website, marketing, signage, and day-to-day communications. It doesn’t have to match your registered company name, and in the UK, a large share of businesses trade under a name that differs from what’s on file at Companies House. Crucially, using a trading name involves no registration process at all. You simply start using it.
The distinction matters because the two names carry entirely different legal weight. Your company name is protected the moment it’s registered. Your trading name isn’t protected by anything unless you take a separate step to protect it, which is where trademark registration comes in.
Trading Name vs Company Name: The Key Differences
The clearest difference is registration. Your company name goes through Companies House as part of incorporation and can’t be changed without filing the correct form. Your trading name requires no filing at all, either to start using it or to change it later.
The second difference is protection. Because your company name is on the public register, no one else can register the same one. A trading name has no equivalent protection; another business could legitimately use the same trading name unless you’ve separately trademarked it.
The third is disclosure. Wherever you use a trading name, your full registered company name, company number, and registered office address still need to appear on official documents, invoices, and your website. The trading name can carry the branding, but it can’t replace the legal disclosure requirements that come with the registered name.
Why It Matters for Overseas Companies
Overseas businesses setting up a UK entity often arrive with a brand name already established in their home market, and a natural assumption that some UK equivalent of a “DBA” or “doing business as” filing applies here too. It doesn’t work quite the same way. There’s no formal UK filing to trade under a different name, which is often a relief once businesses realise it, but it also means the compliance obligations sit in a different place: disclosure and trademark risk, not registration.
This becomes a real issue when a business assumes that simply using a name gives it some protection. If a competitor is already trading under a similar name in the same sector, and neither has trademarked it, there’s no straightforward way to stop them, and no registration record to point to as proof of prior use. For a business bringing an established brand into the UK market, checking trademark availability before committing to that name here is worth doing early, not after the branding is already live.
How It Works in the UK: Choosing and Using a Trading Name
Before adopting a trading name, it’s worth checking it against the same broad standards that apply to company names: not identical or confusingly similar to an existing registered name or trademark, not misleading about what the business does, and free of restricted words that would otherwise need special permission. There’s no formal approval process to pass through, so this check is entirely the business’s own responsibility.
Once you’re using the trading name, your registered company details need to appear correctly wherever the business operates: on invoices, letterheads, contracts, and the website https://www.paulbeare.com/uk-company-formation/, typically in the footer or an “about” or “legal” section. This applies regardless of how prominently the trading name features in your actual branding.
If the trading name has commercial value worth protecting, registering it as a trademark through the UK Intellectual Property Office is a separate process from anything to do with Companies House, and one worth doing early if the brand is central to how the business will be known in the UK market https://www.paulbeare.com/legal-compliance/.
Key Compliance Requirements
The table below sets out what’s actually required once you’re trading under a name different from your registered company name.
Common Mistakes International Businesses Make
The most common mistake is assuming a trading name needs to be registered somewhere, then either delaying launch while searching for a filing process that doesn’t exist, or paying for a service that claims to “register” something with no legal registration to speak of.
The second is dropping the registered company name entirely from invoices, contracts, and the website once a trading name is in use. Branding can lead with the trading name, but the legal disclosure requirement doesn’t go away just because the trading name is more visible day to day.
The third is assuming a trading name carries the same protection as the registered company name, and only discovering it doesn’t when a similarly named competitor turns up in the same market. Checking trademark availability before committing marketing spend to a name is far cheaper than dealing with a naming conflict after the fact.

Questions & Answers
Do I need to tell Companies House if I start trading under a different name?
No. There’s no filing requirement to adopt or change a trading name, unlike a change to your registered company name.
Can two different UK companies use the same trading name?
Yes, unless one of them has trademarked it. Without a trademark, trading names aren’t protected from being used by another business.
Can my company have more than one trading name?
Yes. It’s common for businesses serving different markets or running distinct brands under a single registered company.
Does my trading name need to appear on my website?
The trading name itself doesn’t have to, but your registered company name, number, and registered office address do, regardless of how the site is branded.
