NOW LOCK THE DOOR!
Student households tend to have a lot of high value electrical items such as laptops, tablets, games consoles and mobile phones. This can attract opportunistic thieves, who are known for checking for unlocked doors in residential areas.
Make sure you use the key to lock your front door when you arrive home - just lifting the handle on a UPVC door does not lock it.
Also, thieves are not always deterred just because there is someone in the property.
Register your valuables on www.immobilise.com, where you can record all of the serial numbers of your goods. If they are stolen the Police will work with second hand stores to try and retrieve your belongings.
