Legionella Risk Assessment
System monitoring and control
Remedial and installation works

Our team of qualified risk assessors carry out legionella risk assessments across water systems in accordance with BS8580. From this survey we present an expert report which includes:

  • Identification of risks posed to the water systems caused by the design, condition, use and management of the system.

  • A written scheme which details a monitoring regime showing tasks and frequencies which are required to minimise system risk and ensure legislative compliance.

  • Recommendations for remedial actions such as pipe work and system modification.

  • A schematic drawing of the water system providing details on the location of key assets.


The report is required for the development and implementation of a water hygiene monitoring scheme and programme of remedial works to improve efficiency and compliance.

Once the risks are understood, ongoing monitoring is essential to ensure continued compliance of water systems. Our technicians undertake the monitoring and sampling of water systems outlined in the water hygiene monitoring scheme, these tasks include:

  • Hot and cold system temperature testing and monitoring.

  • Shower descaling and disinfection.

  • Cold water storage tank temperature checks and inspections.

  • Clean and disinfection of cold water storage tanks to BSEN8064.

  • Clean and disinfection of cooling towers and evaporative condensers.

  • Sampling, analysis and interpretation of water for legionella and potability.

  • Calorifier inspection and drain.


We provide a printed electronic site specific log book. As work is undertaken the log book is updated and any areas of concern are addressed immediately through the necessary remedial activities. 

Following the risk assessment and throughout the monitoring programme, remedial work may be required to minimise risks. We will propose solutions, costs and timescales to under take remedial activites.

  • Installation of new hot and cold water systems.

  • Refurbishment of cisterns and pipework modification

  • Supply and installation of booster sets and suitable backflow prevention devices.

  • Installation of calorifiers and thermostatic mixing valves.

  • Tank replacement or refurbishment.

  • Cleaning and disinfecting storage cisterns and water systems in accordance with BS8558.

  • Painting and relining of tanks.

  • Installation of screens, filters and air vents.

All remedial works are undertaken ensuring compliance with the Water Supply (Water Fittings) Regulations.
