History

PTESL Fire Suppression Systems

PTESL Fire Suppression Systems began its journey in 2015 and quickly grew into one of the UK’s trusted specialists in fire suppression systems for data centres, commercial facilities and critical environments.

The Beginning

PTESL was founded as part of Pressure Test Engineering Services Ltd., with the goal of providing highly reliable fire suppression systems to businesses. Although officially established in 2015, the PTESL team brought with it decades of combined fire engineering experience, giving the company a strong expert foundation from day one.

Growing Expertise and Services

From its early focus on gas‑based suppression technology, PTESL rapidly expanded its capabilities. To offer a complete suite of services including:

Fire detection and suppression system design and installation
Testing and maintenance programmes
Cylinder testing and re-gassing
Decommissioning and removal
Specialist services like pressure relief venting and fire stopping.

Fire suppression systems ranged from gaseous mist and water to inert argonite gas, with advice and installation of necessary accompanying pressure relief venting equipment.
