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.
