Many burglaries occur at night, so it's no surprise that more happen after the clocks change in October and the nights get longer.
Burglars are better able to spot patterns in when homes are occupied at night, as lights are more likely to be on when someone is in and off when they're out. Burglars also have a better chance of being able to successfully hide in the dark.
The Co-op research also highlighted the different nature of home break-ins. Between November and March thieves are more likely to use forced or violent entry than in the summer, when burglaries tend to be opportunistic, taking advantage of open windows or doors and not requiring force to gain entry.
