Registering Your Company Name Doesn't Protect It

Plenty of founders register their company at Companies House, breathe a sigh of relief, and assume the brand name is now legally theirs. It isn't. Company registration and trademark registration are two entirely separate processes, and the gap between them is exactly where competitors, copycats, and opportunists tend to slip through often without the original founder realising anything was ever at risk.

Why Company Registration Doesn't Do What Founders Think

Registering a company name at Companies House confirms that no other UK company can register under that exact name. It does nothing to stop a different business from trading under a near-identical brand, using it on a competing website, or building a product around a confusingly similar name in a different sector. That protection only comes from a registered trademark, administered separately by the UK Intellectual Property Office. Founders who skip this step often find out the difference the hard way usually when a competitor with a similar name shows up and there's no legal ground to stand on.

What a Trademark Search Should Catch Before You Even Apply

Before filing anything, the first real step is searching the UKIPO trademark database for names that are identical or confusingly similar to the one being applied for not just exact matches, but phonetic and conceptual near-misses too. This step matters because a conflict discovered before filing is far easier and cheaper to resolve than one discovered after, and the UKIPO doesn't refund the application fee if a clash is found later in the process. A thorough search at this stage is the cheapest insurance a founder will ever buy for their brand.

The First-to-File Trap Worth Understanding

The UK trademark system largely operates on a first-to-file basis, meaning the first party to submit a valid application generally secures the statutory protection not necessarily the first party to actually use the name in business. This creates a genuine risk for founders who trade under a name for months or years before formally registering it: an unrelated party could file first and gain the registered right. There's a partial safety net in UK common law through the tort of "passing off," which lets an earlier unregistered user challenge a later registration if they can show they've built up sufficient goodwill under the name but that's a harder, more expensive legal fight than simply registering early would have been.

What It Actually Costs in 2026

Trademark fees changed meaningfully this year. As of the current UKIPO fee schedule, the standard online application costs £205 for the first class of goods or services, plus £60 for each additional class a roughly 25% increase on the previous fee structure, introduced from April 2026. Founders can also opt into the UKIPO's Right Start Service for an upfront fee of £125, which provides a preliminary examiner assessment before the full application proceeds, reducing the risk of a costly rejection later in the process. For straightforward applications with no objections or oppositions, registration typically takes three to four months from submission to completion.

Picking the Right Classes Actually Matters

Trademarks aren't registered in the abstract they're registered against specific classes of goods and services, and getting this wrong is one of the more common, avoidable mistakes founders make. A name registered only in the class covering software, for example, offers no protection if a competitor uses a similar name to sell physical merchandise. Many founders across the UK startup ecosystem bring in a trademark attorney specifically for this step, not because the filing itself is complicated, but because choosing the wrong classes can leave real gaps in protection that only become obvious once it's too late to fix cheaply.

When Registering Actually Becomes Urgent

A few moments make trademark registration considerably more pressing than "get to it eventually": launching a product or service in the UK market for the first time, receiving investment where investors expect to see demonstrable IP ownership, noticing a competitor already using a similar name, or planning to license the brand or franchise the business model. Each of these raises the practical and financial stakes of not having formal protection in place, and each is a common trigger point where founders realise the informal approach no longer covers the risk.

The Bottom Line

A registered company name feels like protection because it involves paperwork and an official-looking certificate, but it isn't the legal shield most founders assume it is. Trademark registration is the separate step that actually protects a brand name from being used by someone else and given that it typically costs a few hundred pounds and a few months to complete, it's one of the more affordable pieces of legal protection a growing business can put in place before it's needed rather than after.

I came across this breakdown while reading Entrepreneur Plus UK, and it laid out clearly how often founders conflate company registration with brand protection a gap that ends up costing far more to fix than it would have cost to prevent.
