There is no point re-inventing the wheel, so without further ado and with thanks to Kam Hong Leung for doing such a great job, here’s a link to the Contacts List on Kam’s Rotherhithe Community Safety Forum. I will be surprised if you cannot find what you’re looking for there:

As a back up, the SE16 London Voices website is a useful source of local contacts.  It is a little out of date and I have been unable to get hold of its owner, but I find that it is still a very good resource:

Finally, you may want to try Southwark Council. There is a set of phone numbers on their Contacts page. So far I (Andie) have never had an answer to an e-mail query to their general e-mail address, so my own personal strategy would be to stick with the phone numbers and be prepared to be held in a queue:
