Why a business name needs more than one check
“Is this name available?” has four different answers, because a business name lives in four different places. Companies House decides whether you can register it. The trademark register decides whether someone can stop you trading under it. Domain registries decide whether customers can find you. And the sensitive-words rules decide whether the registrar will accept the name at all without a supporting letter.
Most free checkers look at one of these. This one runs all of them from a single form, then tells you exactly which rule any conflict comes from, so you know whether it is a hard stop or something you can work around.
What the free check gives you
A verdict per register, in plain English. For Companies House you see the exact conflicting company, its number and status, and which comparison rule caught it. For domains you see each extension separately. For sensitive words you get the approval body and the guidance to apply to. For trademarks you see how many similar marks exist in your classes, so you know whether the name is walking into a crowded space before you spend anything.
The full report adds the trademark shortlist itself, an AI-assisted risk assessment of each mark, social handles, a passing-off web search and a spellability score. See the step-by-step guide for the order these checks matter in.
Still choosing a name?
If you have a shortlist, check each one here. If you have nothing yet, the name generator produces ideas that have already survived the same checks, so you only see names you could actually use.
