Legionella compliance isn’t optional; it’s essential. As a leading provider and proud member of the Legionella Control Association, Marlowe Environmental Services is committed to the highest industry standards. We offer expert guidance and management for Legionella compliance, working closely with our clients to deliver tailored solutions that ensure regulatory adherence and water safety.
Failing to manage legionella risks can lead to serious health issues, legal penalties, and reputational damage. Proper installation of water systems is a critical part of comprehensive legionella management. Our proactive risk-management approach is aligned with legal frameworks such as the UK’s Health and Safety at Work etc. Act 1974, HSE’s Approved Code of Practice L8, HSG274, and COSHH Regulations 2002, ensuring your business remains compliant and protected.
With years of experience and a dedicated team of UKAS-accredited experts, we deliver tailored legionella compliance services that support a wide range of sectors, including healthcare, education, public buildings, and industrial sites.
We offer a full suite of legionella services tailored to your organisation’s unique requirements, including legionella monitoring and water hygiene solutions. Our process includes specific measures for exposure control, contamination prevention, decontamination, and plumbing maintenance to ensure your water systems remain safe and compliant. Compliance with Legionella regulations requires a comprehensive control program with regular monitoring, risk assessments, and maintenance, as well as routine checks and cleaning of water systems according to risk assessment.
Identify and manage legionella hazards across your water systems with British Standards-aligned legionella risk assessments that identify potential sources of exposure and evaluate conditions that promote legionella growth. Control measures are implemented based on assessment findings to mitigate risks. A Responsible Person is appointed to oversee your water safety management scheme, ensuring all compliance measures are met. Detailed records of monitoring, maintenance, and test results are kept for at least five years, supporting ongoing legionella compliance.
Ensure regulatory compliance and detect potential issues early with routine water sampling and analysis from UKAS-accredited laboratories, where bacteria counts, including Legionella, are regularly monitored. Regular sampling and analysis are essential to demonstrate Legionella compliance and to ensure that bacteria counts remain within acceptable limits as determined by your risk assessment.
Eliminate harmful bacteria with targeted decontamination, disinfection, and biocidal treatment solutions designed to control legionella. Our process includes regular cleaning and maintenance of tanks, hot water cylinders, and removal of dead legs to prevent Legionella growth. We keep your water systems clean by descaling showerheads and taps quarterly to remove biofilm and sediment, and design systems to minimise stagnant water, further reducing risk.
Prove your compliance with full certification and documentation aligned with ACoP L8, HSG274, and HTM 04-01.
Understand and control the risks associated with Legionella in commercial environments. Legionnaires’ disease is contracted by breathing in airborne water droplets containing Legionella bacteria, often from showers, cooling towers, or other aerosol-generating systems. Patients in healthcare settings and individuals with chronic illnesses such as cancer, diabetes, or kidney disease are at higher risk of developing severe complications from Legionnaires’ disease.
Develop and implement a structured water safety plan that includes ongoing management and monitoring of Legionella risks, with the appointment of a competent Responsible Person to oversee compliance and ensure long-term safety.
Customised water treatment services for scale prevention, corrosion control, and comprehensive management of process systems, including hot and cold water systems. Our solutions ensure hot water is stored at 60°C and reaches outlets at 50°C within one minute, while cold water is maintained below 20°C, in line with Legionella compliance standards. Regular temperature monitoring and risk assessments are performed to prevent bacterial growth and ensure safety in commercial and healthcare environments.
Effective disinfection methods, such as chlorination and UV, are carried out as crucial measures to eliminate harmful bacteria and verify the effectiveness of your water hygiene program. It is crucial to document these actions and maintain detailed records, including flushing unused outlets, to demonstrate Legionella compliance and ensure ongoing safety.
Ensure thermostatic mixing valves are safely regulating water temperatures.
Maintain commercial water heaters and hot water cylinders to prevent bacterial growth, performance issues, and ensure Legionella compliance. Legionella bacteria can survive and multiply in water systems where temperatures are between 20°C and 45°C, so it is essential to keep hot water cylinders at the correct hot temperatures, typically above 60°C, to prevent bacteria from surviving and multiplying. Regular inspection and cleaning of hot water cylinders for debris, corrosion, and biofilm are critical steps in maintaining water system hygiene and safety.
Legionella compliance refers to the legal and safety procedures businesses must follow to prevent the spread of Legionnaires’ disease, a severe and potentially fatal type of pneumonia caused by Legionella bacteria in water systems.
Legionella bacteria can multiply in water systems where temperatures are between 20-45°C, making temperature control essential to prevent legionella growth. Hot water should be stored at 60°C and distributed above 50°C, while cold water systems must be maintained below 20°C to reduce risk.
Regular monitoring, sampling, and analysis are required to demonstrate compliance and ensure bacteria counts remain acceptable. Minimising stagnant water by removing dead legs, flushing outlets, and cleaning storage tanks, along with regular cleaning and maintenance, is crucial to prevent conditions where bacteria multiply. Landlords and employers must ensure risk assessments and regular checks are conducted for both hot and cold water systems.
