Hennessy Fire & Security provide an excellent service maintaining our remote monitoring, fire extinguishers, fire and intruder alarms at a very reasonable price.
CONCEPT ENGINEERING - MAIDENHEAD
Hennessy took over our alarm system maintenance a number of years ago, and provide a personalised, professional, and cost effective service to our company, maintaining, expanding and updating that system. I would unreservedly recommend them to others with similar requirements.
BADOCKS WOOD SCHOOL - BRISTOL
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
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.
CADDY WINDOWS - BRISTOL
We have been using Hennessy Fire & Security for both our security alarms and fire alarms for a number of years. The service along with the extremely competive costs make Hennessy the perfect choice for us. Chris and his team provide a fantastic service.

Hennessy upgraded our old alarm system within hours, we can now control the system from our smartphones giving us peace of mind when we are away from the office. The new alarm can be easily set and unset using tags which great for our staff.
