We are third party accredited residential sprinkler installers. We are hoping to start to install commercial jobs to BS EN 12845. I have past commercial design experience and I have done approved training for installation, design and FHC using FHC software for residential systems. I’m wondering what qualifications I need in order to start designing/installing projects? Any information would be greatly appreciated.

To design/install/maintain commercial sprinkler systems (BS EN 12845, LPC Rules etc.) you and your installation/maintenance staff need to be competent in each process. Training for the various design disciplines is critical and designers can sit Designer competence examinations. For installation/ maintenance the company should become accredited by organisations like FIRAS or LPCB which have commercial sprinkler system accreditation schemes. If you go to their websites or call them, you should be able to find all you need to get started. Note: this is not an ‘overnight’ process and you must be prepared for many hours of data/document preparation and have suitable sites for the auditors to visit and make their assessments of your competency.
