Enrich UK Business Dataset

I will share an Excel file containing roughly 5,500 UK companies, each already paired with its Companies House registration number. I now need three additional, fully verified data points for every record:

• Current director’s full name
• Director’s direct email address
• A working telephone number for either the director or the company’s main line

Only information that can be traced back to official sources—e.g., Companies House filings, the company’s own statutory disclosures, or other government-hosted datasets—will be accepted. Open-web guesses, third-party list brokers and generic “info@” emails won’t pass my spot checks.

Because I don’t hold paid API keys or bulk download rights, you’ll need to secure access to these sources yourself (web scraping, API subscription, manual look-ups—whatever is compliant and reliable). Please factor that into your workflow.

Deliverable
An updated Excel spreadsheet, same structure and order as the original, with three new, populated columns for Name, Email and Phone. Before hand-over, test a sample of entries to confirm phone numbers ring through and emails do not hard-bounce.

Completion is defined as at least 95 % coverage across all three new fields and a brief note describing the verification method you used.
