Background: Companies House data only includes registered office addresses. We require the actual trading addresses (principal place(s) of business) for analysis, marketing outreach, or compliance.
Objective: Build a pipeline that takes a list of UK company numbers (and optional SIC codes), and outputs a CSV with:
Company number
Company name
Number of employees
Turnover (where available)
SIC code(s)
Trading address (street, city, postcode)
2. Scope of Work
Core Data Ingestion
Download/ingest the monthly Companies House bulk CSV (or use the Companies House API) to get company number, name, postcode, SIC code(s).
Trading-Address Enrichment
Primary method: Parse iXBRL filings for .
Fallback method: Query a Places‐API (e.g. Google Places or Foursquare) by “company name + postcode” to retrieve formatted address.
Data Merging & Cleanup
Consolidate registered vs. trading address fields.
Standardize address formatting.
Deduplicate and log failures for manual review.
Export & Delivery
Export a final CSV with the key fields.
Provide a short one-page README describing usage and dependencies
4. Required Skills & Experience
Strong Python (or Node.js) coding for data pipelines.
Experience parsing XBRL/iXBRL (e.g. python-iXBRL or equivalent).

Familiarity with web-scraping frameworks (Scrapy, BeautifulSoup, Puppeteer) is a plus.
Data cleansing and address standardization best practices.
