What this check covers
It looks for an exact match among live companies, ignoring capitals, punctuation, a leading "The" and endings such as Ltd. Then it shows the names next to yours alphabetically, so you can spot close calls.
It doesn't include dissolved companies or apply every Companies House rule. Read our guide to company name rules, and run the official name checker before you register. Your typed name stays in your browser.
