Accrediting organisation:  

Certificated by Envex



Awareness of legionella and the potentially serious effects of Legionnaires’ disease have grown in recent years, often fuelled by the publicity from the major outbreaks, which have led to prosecutions under the Health & Safety at Work Act. For organisations of all types, it has become more important that individuals understand their legal duties and the serious   consequences of a failure to comply with the law.

The L8 ACoP sets out legislative obligations and states that those involved in legionella management: ‘should have such ability, experience, instruction, information, training and resources as to allow them to carry out their tasks’. Successful completion of this course the delegate can be regarded as a competent person. The course is accredited by Envex with an attendance certificate.
