British teenagers collectively caused STG14 million ($A21.56 million) worth of damage to their parents' homes by throwing parties that have got out of hand, a survey suggests.

Around 17 per cent of parents have had to make a claim on their home insurance policy for accidents and damage caused by a teenager's party, with the average claim being STG117 ($A180.21).

The most common problems caused by teenage parties are general rubbish and mess, followed by broken furniture, trampled gardens and plants, stains on the carpets and burns on sofas and chairs, according to Allianz Insurance.
