ACoP L8 Compliance

Legionella baceria grows in warm water typically between 20 and 50 degrees centigrade, but proliferates fastest in stagnant water at 35 to 46 degrees centigrade.

At the heart of the Health and Safety Executive's ACoP L8 for control of legionella, is to undertake a risk assessment of the entire water system and implement a scheme of control.

Sampling and Analysis

Normally, the routine analysis of domestic water systems is not recommended by the ACoP L8.

However, under certain circumstances, such as where the temperature regime cannot be maintained, the testing for Legionella and other organisms is seen as being essential in the overall control of a system. In the case of cooling systems, the sampling and analysis for Legionella Pneumophila is a quarterly requirement.

Tank Cleaning and Disinfection

Cleaning and disinfection of cold-water storage tanks and complete water systems are carried out to BS8558 standards or the ACoP L8 by our trained technicians.

All of our work carries a Completion Certificate.

Our Solution to Combatting Legionella

We can undertake an assessment of your water systems, highlight any areas of potential risk and provide you with a detailed legionella risk assessment report.

We will make recommendations for the implementation of an effective monitoring and maintenance program, which will minimise the risk of a legionella outbreak.

Where a risk assessment is already in place, we can review this for you or undertake an audit.

Electronic Logbooks

Our powerful, yet user friendly web based log book system is designed to support you in meeting your duty of care.

Data is uploaded via the internet to a secure website where it can be analysed and viewed securely, allowing you to manage your legionella control regime, cost effectively and accurately.

Temperature monitoring

We can offer you a tailored programme of monitoring and remedial maintenance to ensure ongoing and consistent compliance with legislation.

As part of this regime, the following system components should be checked regularly:

Hot and cold water outlets
Sentinel outlets
Cold water storage tanks
Thermostatic Mixing Valves (TMVs)
Flow and return temperatures on hot water systems
Calorifiers and hot water cylinders
De-scaling and disinfection of shower heads and hoses
Flushing of little used outlets
Water softener servicing

Thermostatic Mixing Values (TMVs)

Increasing hot water temperatures at outlets to over 50 degrees centigrade is necessary to control legionella bacteria, yet this can increase the risk of scalding.

TMVs will effectively avoid scalding, but must be correctly selected, installed, regularly serviced and maintained to prevent the proliferation of legionella.
