Companies House Public Data API Access

Hi all.

I was wondering how I would go about obtaining an API key. We would like access to Companies House Public Data API, and would like to be able to retrieve a company SIC codes within a spreadsheet.

I’ve created an account for Companies House and was redirected here by the support email.

Many thanks,

All documentation can be found
Please note that the API service is not intended for bulk retrieval of every company’s data of course.
There are bulk products (for example Companies House) for that and others if you are interested.
