Company Name Checker
Free UK company name checker using Companies House rules
Company Name Checker is a free, independent tool for checking whether a UK company name is available. It applies the Companies House "same as" rules from Schedule 3 of the 2015 Names Regulations, stripping out endings like "Ltd", punctuation, accents, "The" at the start and a final "S", then compares what's left against every live UK company. A simple exact-match search for "Acme UK Ltd" would miss "The Acme Company Limited"; this one catches it and shows the reduced form Companies House compares.
Each result places your name on an A-to-Z view of the register, lists similar names that could still draw a "too like" objection, and links any clashing company to its Companies House record. Data comes from Companies House's monthly file of live companies, with a live Companies House search when that finds no clash, so recently registered companies are caught too.
Around the name check sit a business name generator that checks every idea, a .co.uk, .uk and .com domain checker, a UK company search with filing deadlines, a VAT number format checker, and guides to registering a limited company, identity verification, confirmation statements and trade mark searches. Every fee and rule carries an official source and a check date.
