Companies House can give you a broad insight into your customer's company 

  • directors' names and service addresses
  • accounts information
  • confirmation statement
  • charges
  • other business activity

All of the above will be fundamental and a vital foundation when chasing a debt to build that initial picture of how likely it is to recover your outstanding invoices.

The Section within Companies House  on Persons with Significant Control can give you another avenue - an additional  person to contact or another address to try.
