Desk Research for London Council contact details

I need some desk research done to find contact details for particular London Borough Councils.

I am looking for contact details for the head of regeneration for each London Borough and details of any heads of housing partnerships for the council.

Attached is a spreadsheet with examples details for 3 councils and a PDF showing all the London Boroughs.

All the info is available on the council websites by searching for regeneration and Housing.
Would you be able to help with this?

Regards
Rob
