Legionella (Legionnaires' disease) Risk Assessments

It is a legal requirement to have a legionella risk assessment of all cold and hot water systems. The risk assessments is usually carried out as a part of our legionella risk management programme which help manage the risk of Legionnaires' disease. Our Risk assessments have been developed in accordance with the guidelines and recommended practices issued by the UK Health & Safety Executive L8 and the Health and Safety Commission (HSC). A risk assessment will have a significant impact on reducing liability should any problems occur.

On average there are 200-250 reported cases of Legionnaires’ disease – a potentially fatal form of pneumonia – in the UK each year.

Following a site survey, our qualified and experienced risk assessor will produce a comprehensive report. The legionella risk assessment report will identify any risks as well as any remedial action necessary to meet current standards and legal requirements.

The report will also include a schematic drawing of your water system and a guide to complying with the Associated Code of Practice (ACOP L8).
