Thank you for the investigation. It’s great to get responses to queries about this service and you’ve provided a lot of detail here for an issue which is technically outwith the API itself.
I appreciate lots of the queries around data are over “old” or “exceptional” records / cases. I’m less interested in “completeness” than “comprehension” and “consistency”. To know what Companies House does (and doesn’t do) and to ensure that I can provide consistency to our users.
I appreciate that the data is subject to the requirements of legal procedure and that this a “look up” service is a secondary requirement and that there will be certain operational constraints e.g. what data is stored, from when. I have followed up on the subject of data “silently disappearing” in another post.
Thanks again.
