Tennals Fire and Security Ltd

MHS Alarm Services Ltd was originally formed in 1972 as Midland Home Security. A few years later the firm changed its name to MHS Security as work increased outside the Midlands area. The firm enjoyed a continued steady growth. In 1989, MHS Security joined forces with Delta Alarms a southern based company to extend its national coverage. In 2009 MHS was acquired by Tennals Group, and ever since have continued that growth organically, also through numerous acquisitions. With over forty years experience in this industry, and a robust client base we have grown through recommendation only. As a business we pride ourselves on working to third party accreditation, delivering a service our clients expect through a competitive unique pricing model with no hidden extras. Currently Tennals are one of the largest independent owned fire and security organisations in the UK
