Please join the Leaseholders Association of Southwark 2000 (aka 'LAS 200'.) They are very knowledgable, run by volunteers but volunteers who know their stuff, and have successfully fought against Southwark on various excessive charges in years gone by, and will help you. They don't reply very quickly because as I said they are volunteers and many of them/us work, but maybe you may have skills you could offer too. (ie ask not what your LAS2000...) but please do consider joining, and they may be able to advise. However, everyone's posts above has been pretty good too! LAS2000 P O Box 23394 LONDON SE16 2WA Write and ask for details of joining. I think it's ?30 a year or something.
