Before deciding on a name for your business, do research into its availability and whether other companies are using a similar name. Check that the name isn't already registered with Companies House using their name availability checker and be aware of any trademarks or registered intellectual property rights. Search the domain names registry to check that it's possible to register a relevant name for your website. You can use Nominet's WHOIS web tool to find out if the domain name is already registered in the UK and who the owner is if it's already registered.
