The exodus of students from the family home will see £300 million worth of children's belongings left behind.
Research by Lloyds TSB insurance has looked at the possessions many youngsters choose not to take with them when they head off to uni and their potential value.
Some 73 per cent of parents questioned said their offspring leave belongings with them after they move out, with an average value of £735.
Tim Downes, senior claims manager at Lloyds TSB Insurance, has called on all mums and dads to know the value of such items for insurance purposes after 12 per cent of respondents admitted they had no idea how much the stuff was worth.
"Ensuring you have a comprehensive cover will help give you peace of mind, knowing your valuables are protected," he added.
Over half (55 per cent) of parents cleared out their kid's bedroom within a few months of them moving out, while the most popular function for it is to be turned into a guest room.
