Our History

Alerter Group plc is a multi million pound, profitable, stable and expanding company with thousands of customers across the UK and Ireland.

Historically specialising in providing communication and alarm systems for Deaf and hard of hearing people, more recently our product portfolio has been expanded to provide emergency refuge communication systems for people with other disabilities as well as support personnel such as fire wardens.

Deaf Alerter is a product that was initially developed by Evets Communications Limited, a sister company in the ECL group formed in 1980, which continues to provide radio and data communications for the radio communication and broadcast industries. The company hence has a long history and significant experience in radio technology. The Deaf Alerter product is now exclusively available from Alerter Group plc and its authorised partners.
