Hi SazzleLondon,
sorry to hear of your experience; I'm glad you were OK though.
I've just recently started a Neighbourhood Watch in my street (down in Tooting) and want to say that the local SNT (safer neighbourhood team - police) have been marvellous. You could also speak to your local SNT about something called "Flash", which is a free service from the Fire Brigade which checks your fire safety AND locks & gives you advice on how to improve areas where you might be vulnerable.
Even if you aren't able to get a Neighbourhood Watch (NHW) started soon, the council might be able to provide you with their Meerkat NHW window stickers which warn people you're part of a watch & are apparently a deterrent. Having said that, I asked the council about starting a watch in my street, and within a month they had organised the launch meeting.
Anyway, keep safe & good luck!
Tracey
