Research from Newcastle Building Society also revealed that almost one in five (17%) people of university age do not have home contents insurance.
Despite this, more than a third (35%) of students have left the house without locking the windows and 18% have forgotten to lock the door.
Other acts of forgetfulness by 18 to 24-year-olds included failing to check their smoke alarm battery (57%), leaving the house with washing machines and ovens still running (56%) and leaving possessions on display (42%).
The findings show that of the 1,990 students surveyed, 14% have made a claim, with 7% being for burglary and 2% for damage from appliances.
Wendy Lee, commercial director at Newcastle Building Society, said: "It is worrying to see the number of 18 to 24-year-olds who admit to forgetful acts over a year.
"It stands to reason that leaving your home without locking the doors or setting the alarm creates a risk for burglary but it can also affect your home contents cover should you come to claim."
