IDH Alarms Co. Ltd has been established since 1982, in the beginning only installing intruder alarm systems in mainly domestic applications. After having been awarded NACOSS GOLD accreditation in 1994 (now NSI GOLD) IDH Alarms successfully secured several major contracts within local authorities, and the local constabulary. IDH Alarms still delivers maintenance and installation services to these contracts almost 25 years on. Over the last 32 years, IDH Alarms has embraced the opportunity to improve and diversify taking into account the needs of an ever growing customer base.

IDH Alarms is a NSI Gold approved installer of electronic security systems. All systems installed by us will be of the highest standards of workmanship, and comply with the latest European Standards EN50131 and the UK’s equivalent PD6662. All engineers have to be vetted to BS7858 standards. IDH Alarms can design, install, commission and maintain systems in a wide variety of premises.
