Hi
I live in South London
Can I suggest you take a look at the crime statistics for the areas in which you are interested:
http://www.crimestatistics.org.uk
Borough of Lewisham (including Lewisham)
Crime Statistics: ALL CRIME for Lewisham Apr 2004 - Mar 2005
Borough of Greenwich (including Blackheath)
Crime Statistics: ALL CRIME for Greenwich Apr 2004 - Mar 2005
Ofsted – Home Page is the government standards agency for UK schools
BBC has some league table information
BBC NEWS | Education | League Tables
Each London borough has their own website with lots of information about nurseries and schools and the local areas.
Travel in most areas of London is good with train, underground and Docklands Light Railway (DLR). For example Bromley is the last London borough before Kent. Train Travel from here is about 25 – 35 mins to Central London, underground to Tower Hill is about 10 – 15 mins and then DLR to Canary Wharf 10 – 15 mins. So is more a case of find the best place to live for a good work life balance.
I hope this helps. I would be happy to found out over information if required.
Regards
Mark
