The Hennessy team provide a reliable and dependable service to our school. Since they have taken over maintenance of all systems, our call outs have reduced and no longer have any false alarms.

St John Church - Hackney, London

Jacob Darlison - Worship Pastor

Hennessy Fire & Security provided a competitively priced high-quality installation for an old building. They have been great with communication and the installation was completed on time and integrated well in to the church aesthetic (paramount when dealing with heritage grade structures). The system is easy to understand and perfect for the needs.
