According to the most recently available government statistics (Autumn 2011) the annual figures for burglaries into all building (i.e. dwellings and others) in Essex are up to a figure of 13,855.
if you think about it that means you have a very real chance of being burgled all the time – unlike the lottery were you stand more chance of dying each week than winning.
However, you can drastically reduce your chances of being burgled by (a) taking sensible physical security measures such as fitting suitable locks and (b) fitting an alarm.
