Checks if a proposed company name is already registered, or if there is an existing company name which is too similar to the proposed name, under the Companies House 2006 regulations.

If similar name(s) are found the method will return the name entered and a list of companies, detailing the company name and company number, with names the same as or too similar to the proposed name.
