Sectors
Covered
We operate across the most technically demanding sectors, where fire safety system failure is not an option.
Generation & Energy
Power Station
Generation assets demand zero-tolerance fire safety. We deliver site-proven systems for turbine halls, control rooms, and HV switchgear — including Leeds Waste to Energy and similar generation facilities.

Transmission Infrastructure
National Grid Substation
High-voltage substations require specialist coordination. Our teams are cleared for live-site working alongside National Grid operations, installing and commissioning fire protection with active HV equipment present.

Mission-Critical Facilities
Data Centre
Uptime is non-negotiable. We install VESDA aspirating detection, suppression-integrated FD&A, and thermal monitoring for hyperscale and colocation environments — without interrupting live operations.
