A business name is one of the few early decisions that's genuinely difficult and expensive to reverse once customers, suppliers and search engines have attached to it. This checklist walks through every practical check a UK founder should complete before filing anything.
Start with what the name needs to do
Before generating name ideas, write down the jobs the name needs to perform: it should be easy to say aloud and spell correctly from hearing it once, memorable enough that a customer can find you again without a saved link, flexible enough to cover reasonable future product expansion, and free of unintended negative meanings in English and any export markets you might target. Names that pass all four tests tend to outperform cleverer names that fail one or two of them.
It's worth explicitly deciding whether you want a descriptive name (clear about what you sell, but harder to trademark distinctively and harder to extend into new categories), an evocative or invented name (more brandable and trademark-friendly, but requires more marketing spend to build recognition from zero), or a founder name (personal and authentic, but can feel limiting if you plan to sell the business eventually).
The availability checks, in order
- Companies House name search — check no identical or 'too similar' name is already registered as a UK company.
- UK Intellectual Property Office trade mark register — search for existing marks in your goods/services class that could block registration or lead to a legal challenge.
- Domain availability — check the .co.uk and .com for your exact name and close variants.
- Social media handle availability — Instagram, TikTok and Facebook at minimum, even if you don't plan to use all of them immediately.
- A plain Google search of the name plus your product category — to catch existing informal use, forums, or a company operating under the name without formal registration.
Running these checks in this order is efficient because each one is progressively more work to fix if it fails — a taken domain is a minor inconvenience, but a trade mark conflict discovered after you've built a brand around the name can be existential.
Reading the name out loud, to other people
Names that look fine written down sometimes fail badly when spoken — unusual spellings, unclear word boundaries ('Pen Island' problem) or homophones with unrelated words can undermine an otherwise strong name. Say your shortlisted names aloud to at least five people outside your immediate team, ask them to spell it back to you and to guess what the business sells, without giving them any other context.
This simple test catches a surprising number of problems before they become expensive: names that get consistently misspelled will lose customers trying to find you again by typing the name into a search bar rather than clicking a saved link, which matters more for a repeat-purchase e-commerce brand than almost any other consideration.
Legal structure and the registered company name
Remember that the name you trade under (your brand name, on your website and packaging) doesn't have to be identical to your registered company name at Companies House — many UK businesses trade under a brand name while their legal entity has a more administrative name, using a 'trading as' designation. This gives some flexibility if your ideal brand name is unavailable at Companies House but is available as a trade mark and domain, though you should still avoid a company name so different from your brand that it confuses suppliers, banks or HMRC correspondence.
Future-proofing the name
Consider where the business might realistically be in five years, not just at launch. A name tightly scoped to one product ('London Yoga Mats') can become a liability if you expand into adjacent categories, whereas a slightly broader name gives you room to grow without a confusing rebrand. Equally, avoid a name so broad and generic that it fails to differentiate you at all — the strongest names sit in the middle: distinctive enough to own, broad enough to stretch.
If international expansion is a realistic medium-term goal, check that the name has no awkward meaning or pronunciation issue in your most likely export languages, and confirm that the .com and equivalent country-code domains are available or realistically acquirable.
Finalising and locking the name in
Once a name clears every check, move quickly to lock it in before someone else does: register the domains, file the Companies House registration, submit the trade mark application, and claim the core social handles, ideally within the same week. Names that pass every check are rarer than founders expect, and a name that's freely available today can be registered by someone else within days if you delay after publicly discussing it, including in casual conversations with suppliers or freelancers who might repeat it.
