Homeowners could lose out if they do not know the value of the contents of their loft, says Saga Home Insurance.
The insurance provider says many people undervalue their lofts, which could cause future claims to be unsuccessful.
"Often the most unexpected items turn out to be valuable," said Andrew Goodsell, Saga chief executive.
"If your possessions are undervalued, you could find that you receive only a fraction of their worth in the event of theft or damage," he added.
Saga Home Insurance has increased its single item limit from £1,000 to £2,500 to help homeowners insure their most valuable possessions.
The insurance provider recommends homeowners mark valuable possessions with ceramic non-scratch marking pens and photograph them to increase the chance of the police tracing them if they are stolen.
Saga is currently offering new customers a ten per cent introductory offer when they sign up for home insurance, plus a five per cent discount if they apply online.To read more about Contents Insurance, click here.
