About Company Name Checker

What this site is

A free toolkit for people starting or running a UK limited company: check whether a name is available, understand why a name clashes, compare ways to register, and keep track of filing deadlines.

Not a government service

Company Name Checker is independent. It is not affiliated with Companies House or any part of the UK government. Only Companies House can accept a company name, and it does that when you file.

Where the information comes from

Company data comes from Companies House's free public data. Fees, rules, dates and prices come from official pages and providers' own published pages. Each one is listed with its source and last-checked date on sources, and every change is logged on data updates.

How content is made and checked

Research and drafting are done with the help of AI tools. A person checks the key facts against the official source before they are published.
