UK genealogy companies

Thanks to a database from Companies House you can access, free of charge, UK company financial accounts and information about directors and secretaries (year and month of birth!) as well as other information throughout the life of the company. That's over 170 million company records. Unfortunately you can't search by director name.

Try out the beta service here. I searched for companies with names involving genealogy/family history. Not all are active.
