Homeowners should be careful about leaving valuable goods on show in their property in the run-up to Christmas, the British Insurance Brokers Association (Biba) has warned.Graeme Trudgill, technical and corporate affairs executive at Biba, noted that the festive period brings with it a renewed threat of break-ins.If you have got valuable items, dont leave them where people can see them, he said.With Christmas coming up, unfortunately burglars are known to head for the Christmas tree and take the presents from underneath.Homeowners should also keep their car keys in a safe and secure place, as thieves will often attempt to gain access to the keys first rather than simply breaking into the family car, Mr Trudgill said.The comments come after a recent piece by unplugged.rcrwireless claimed that the rise of digital, online technology has served to poses questions about the future role of kitchen appliances in the home.
