Services
Our main areas of activity involve enabling customers to comply with their responsibilities to minimise the risk of Legionnaires disease encompassed in ACoP L8 'The control of legionella bacteria in water'. As always in risk management the process begins with a formal legionella risk assessment. From this we outline remedial measures and a written legionella control scheme which are designed to reduce and control the risk.
