Hot & Cold Services


The terminology of hot and cold water system is often used interchangeably with domestic systems even although these are found in the vast majority of commercial, industrial and institutional premises.   Prior to the publication of the ACoP (L8) these systems formed the most common arena where legionella bacteria outbreaks were identified, with improved treatment regimes these instances have declined in volume – that doesn’t mean the risk within these systems has been eliminated!  

What it does mean is that the adoption of the practises and policies contained within ACoP (L8) need to be carefully adhered to for hot and cold water systems with an appropriate monitoring and treatment programme in place.
