Do customers, tenants, service users, the public or employees have access to a property that you control?  Can other people be affected by what you are doing?  If the answer is yes to either of these questions, then you need to act to control & prevent Legionella bacteria.  These requirements are found in the Health & Safety at Work Act 1974, The Control of Substances Hazardous to Health Act (COSHH) 2002 & The Management of Health & Safety at Work Regulations 1999.  Failure to do so can lead to unlimited fines with a starting point of £10,000, prosecution and even imprisonment, the Crown Prosecution Service have also previously authorised charges of corporate manslaughter for deaths related to Legionella failures.  In support of these health & safety legal requirements the HSE has published the 4th Edition of the Approved Code of Practice for the Control of Legionella Bacteria in Water Systems commonly called ACOP L8.

The HSE's Approved Code of Practice for the Control of Legionella Bacteria ACOP L8 & the Department of Health's Technical Memorandum HTM 04-01

In November 2013 the Health & Safety Executive released the 4th edition of the Approved Code of Practice for the Control of Legionella Bacteria in Water Systems commonly called ACOP L8.  The code of practice has been released by the HSE with the consent of the Secretary of State.  It gives practical advice on how to comply with the law.  If you follow its advice you will be doing enough to comply with the law in respect of those specific matters on which the code gives advice.  The code of practice has a special legal status.  If you are prosecuted for a breach of health and safety law, and it is proved that you did not follow the relevant provisions of the code of practice, you will need to show that you have complied with the law in some other way or a court may find you at fault.


The Health & Safety Executive have also released technical guidance documents

HSG 274 Part 1 The Control of Legionella Bacteria in Evaporative Cooling Systems

HSG 274 Part 2 The Control of Legionella Bacteria in Hot & Cold Water Systems

HSG 274 Part 3 The Control of Legionella Bacteria in Other Risk Systems

HSG 282 The Control of Legionella & Other Infectious Agents in Spa-Pool Systems

The Department of Health have also released Health Technical Memorandum (HTM) 04-01: Safe Water in Healthcare Premises with accompanying guidance documents parts A, B, C and specification D 08 for Thermostatic Mixing Valves.  HTM 04-01 is a requirement for all health and care environments, it does not replace the HSE's ACOP L8, it is designed to work along side it and concentrates on the increased performance criteria required to address the potential increased risk of Legionalla in health and care environments.

What is Legionella Bacteria?


Legionella is a naturally occurring bacteria, it is normally only found in low quantities which presents little risk.  However, in hot & cold-water systems, air conditioning and even in soils & composts the bacteria can grow and in larger quantities the various strains of Legionella bacteria can present a risk to life.  The bacteria thrive in temperatures of between 20c and 45c.  If inhaled Legionella bacteria can cause one of several diseases all of which can be fatal including Legionnaires Disease. 


The potential of this bacteria is so serious that the HSE publishes a monthly legionella report which is freely available on the HSE website.  In recent years we have seen a mortality rate of around 8% but as high as 40% in more susceptible groups, that is a higher mortality rate than some cancers.
