Insurance warning on burglar alarms

HOUSEHOLDERS who install security alarm systems without checking the credentials of the suppliers could find that insurance companies turn down their policy claims. The British Insurance & Investment Brokers' Association says insurers usually require suppliers to be approved by the National Approval Council for Security Systems (Nacoss).

A list of approved companies is available from Nacoss, Queensgate House, 14 Cookham Road, Maidenhead, Berkshire SL6 8AJ. 0628 37512.
