Business headquarters postal address appending

I have a list of the names of 1000 organisations in the United Kingdom along with their website urls. See the attached example file.

We need to find and append the headquarters postal address for each organisation.

I think the quickest/ easiest way is to search google with a phrase such as "Keltbray Group headquarters address" or "D&D London headquarters address".... or use head office or "HQ" instead of headquarters.

Or search "Birmingham City University address" with the headquarters or HQ or Head office

Another source of the information may be Companies House. so:
https://find-and-update.company-information.service.gov.uk/company/02859789

If we wanted to proceed, we would need the task doing quickly in 24 - 48 hours maximum

If you are interested please can you complete five further rows in the spreadsheet and send it back with your reply. This so that we can see you understand the task exactly.

Thank you..
