There definitely are home edders in that area (we are South West London). There's a West London home ed yahoo group, which would be a good starting point. It shouldn't be too hard to find, but let me know if you can't locate it.
Hello lilyfire, I wonder whether you could help.... we also live in SW London and am thinking about HE for my daughter who is currently 21 months. Would you mind pointing me in the right direction re. Home ed groups? I'm aware that there is a group in Kew and also one further out near Surbiton, I think. Do you know of any more. We are in Twickenham, so the Kew group is probably our nearest unless you know of any others?
