Installing timers on your lights is a good way of creating the appearance that the property is occupied.
Remember to set them so that they fit in with your day-to-day routine, and in rooms you normally occupy at night.
This means placing timers on lights in the lounge and perhaps the main bedroom.
Most people tend to place timers in the hall or stairs lights - but when was the last time you settled down to an evening of relaxation on your staircase?
