Water Hygiene Services

 

What Are Water Hygiene & Legionella Services 

Water hygiene services are the practical measures that prevent harmful bacteria — particularly legionella — from proliferating in building water systems. A water hygiene programme typically covers legionella risk assessments, system cleaning and disinfection, temperature monitoring, water sampling, TMV servicing, backflow prevention and ongoing maintenance of tanks, pipework and valves.

​

Under ACOP L8 and HSG274, duty holders have a legal obligation to assess and control legionella risk in their water systems. A properly designed water hygiene programme meets that obligation, protects building users from harmful pathogens, and provides a consistent audit trail that demonstrates your controls are working.

Controlling Legionella in Your Water Systems

Legionella bacteria are naturally present in water, but they can multiply to dangerous levels when conditions in your system allow, such as when water is stored, stagnant, or kept at the wrong temperature. Under ACOP L8, every duty holder must take practical steps to assess and control that risk, to prevent the growth of legionella in commercial water systems. That’s where Titan Water can help.

​

Our engineers provide all the services you need to keep legionella under control and stay compliant:

• Legionella Risk Assessments – detailed surveys of your hot and cold water systems, identifying potential breeding points and producing an action plan for compliance.

​

• Ongoing Monitoring – temperature checks, flushing, inspection, and logbook management to ensure control measures remain effective.

​

• Water Sampling and Laboratory Testing – routine or reactive sampling through UKAS-accredited laboratories, with full reporting and interpretation.

​

• Tank Cleaning and Disinfection – physical and chemical cleaning to remove scale, sludge, and biofilm where bacteria thrive.

​

• TMV Servicing – checking thermostatic mixing valves for temperature control, performance, and hygiene compliance.

​

• Backflow Prevention and RPZ Testing – ensuring water cannot flow in reverse and contaminate clean supplies.

​

• Legionella Remedial Works – fixing identified risks, such as dead-legs, poor insulation, faulty valves, or temperature issues.

​​

• Full Documentation and Support – every visit logged, every action evidenced, to give you an audit trail that stands up to scrutiny. Our team can support you in creating a robust control scheme that helps to reduce your risks and protect your building's users.

 

All services are delivered in line with ACOP L8 and supporting HSG274 guidance.

 

We don’t just tick boxes - we help you understand where your risks lie, what actions matter most, and how to keep your system safe over the long term. Whether you manage a single building or a multi-site estate, Titan Water provides the technical knowledge and hands-on service you need to stay compliant and confident.

What Are My Legal Responsibilities Under ACOP L8

ACOP L8 (Fourth edition) is the HSE’s Approved Code of Practice titled Legionnaires’ disease: The control of legionella bacteria in water systems. It sets the expectations for duty holders and is supported by HSG274 technical guidance. Under ACOP L8, duty holders such as employers, landlords, and building managers must control the risk of Legionella bacteria in water systems. This includes identifying and assessing sources of risk, implementing and maintaining effective control measures, and keeping accurate records.

 

You must appoint a competent person (the “responsible person”) to manage these duties, ensure regular monitoring, cleaning, and disinfection of water systems, and take swift corrective action when needed. Compliance with ACOP L8 helps meet legal obligations under the Health and Safety at Work etc. Act 1974 and COSHH Regulations.

 

​

Can Titan Water Manage All of My L8 Compliance Needs?

You can’t subcontract your legal responsibilities for Legionella control, but you can appoint specialists like Titan Water to help you meet them. As the duty holder, you remain legally responsible for managing the risk of Legionella and other bacteria under ACOP L8 and HSG274. That means ensuring risks are identified, control measures are implemented, and systems are properly maintained and documented.

​

Titan Water can handle every operational aspect of compliance on your behalf - from Legionella risk assessments and water testing to cleaning, monitoring, and record management. Our experienced team ensures that all required tasks are carried out to the highest standards, keeping your systems safe and your documentation audit-ready.

​

In short, while you retain the legal duty, Titan Water provides the expertise, systems, and full range of services needed to help you achieve and maintain compliance confidently and efficiently.
