At Active Suppression Laboratories (ASL), we specialise in the independent testing and inspection of fire suppression systems, with a focus on sprinkler heads and Watermist nozzles. Based in the West Midlands, we serve clients across the UK who rely on us to confirm the performance and reliability of their fire protection systems.

As the demand for suppression systems grows, so too does the need for rigorous, third-party testing. We help ensure that your systems meet safety standards and function as intended when it matters most. Our laboratory operates in accordance with the LPC Sprinkler Rules and relevant European Standards (EN 12845 & EN 12259-1), offering a range of specialist services designed to assess the condition, operation, and performance of installed sprinkler components.

Whether you’re looking to meet regulatory requirements or simply ensure long-term system reliability, ASL provides expert, independent verification to give you confidence in your fire suppression systems.
