Platform provides a search interface for company information. Search is heavily crippled by CAPTCHA and delays on multiple searches, features that severely limit scraping. The information provided is also limited and does not include address details.

It is possible to browse the registry without a search term by selecting other criteria, though to do so would take a very long time.

Reviewer comments

Added title and more details. I am being lenient with the lack of addresses provided as it could be argued that this does not constitute a companies register. I have decided to give it the benefit of the doubt.
