I need a lightweight web page that mirrors the “Advanced Search” on Companies House yet goes one step further: the resulting CSV must also list the directors’ names and addresses. In other words, the download should contain at least Company Name, Company Status, Director Name and Address fields instead of omitting the people data the way the public site currently does. You are free to pick whatever stack you’re most comfortable with—Python (Flask/FastAPI), Node/Express, or PHP are all fine—as long as the solution: • Pulls data through the official Companies House API, respecting its authentication and rate-limit rules • Lets me apply the same filters available on https://find-and-update.company-information.service.gov.uk/advanced-search (company status, incorporation date ranges, SIC, etc.) • Adds the extra director-level information to the export • Produces a clean CSV file for download in a single click • Runs from a simple browser page I can host myself (no login required) Please include concise setup instructions and any small helper scripts so I can deploy and test everything quickly within the £50 scope.
