Hi,

As a first step you could try: Companies House this has the details of all PSC’s provided to Companies House. It is in JSON formet

Thanks you very much, it will help me ,
is there any dumps like this but with details of companies provided to Companies House?

And maybe there is some db dump where list of all officers of companies provided to Companies House?
