If you advertised your holiday plans on social networking sites such as Facebook, Twitter about your exact location and your home gets burgled while you were away-you may face a crackdown from the insurance agency.
Insurance companies have decided to take information being put social networking sites into account when analysing claims.
Research into the online activities of users found that thousands regularly leave themselves open to their homes being raided.
A survey from the Co-operative Insurance of 3,000 has found a third of Britons who use the sites unwittingly put themselves at risk of being burgled.
Some 36 per cent use the sites to update friends on their whereabouts, while 35 per cent count down to events such as holidays, potentially alerting criminals to when their home will be empty.
