UK Business Contact Data Compilation

I have a master spreadsheet of 26,811 UK businesses, each already tagged with its registered name, Companies House number and address. The task is to enrich every record with fresh, verifiable contact and employee-count data drawn from three places: the company’s own website, its LinkedIn page and UK government datasets such as Companies House, Gender Pay Gap, ONS or any other relevant Gov.uk source you regularly use.

For every business I need:
• Director or owner’s name, followed—always in this order—by their email and phone number where they are publicly available.
• After that, the general business email and phone number.
• Head-count figures captured separately from each of the three sources above; if the numbers conflict, keep all three.

Accuracy matters more than speed, so please cite each URL you used beside the data you collect; it will help me spot-check and sign off the file quickly. Deliver the finished work in my existing spreadsheet format (CSV or XLSX), keeping the column order intact and adding the new fields at the end.

I will review a 200-row pilot first to confirm layout and reliability, then release the go-ahead for the full dataset.
