What Does A Legionella Water Testing Company Do?

We at Legionella Water Testing Company in Tyne and Wear identify the presence of legionella bacteria in water systems to prevent outbreaks and meet legal obligations.

We carry out on-site sampling, send water samples to accredited laboratories, and provide detailed reports with clear guidance. We work with duty holders and facilities teams to help them meet their responsibilities under UK health and safety law and to protect staff, residents in Tyne and Wear, or visitors from exposure to a potentially deadly bacterium.

What Types Of Water Systems Need Legionella Testing?

Legionella water testing systems are needed for the following:

• Cooling towers and evaporative condensers – High aerosol generation and ideal conditions for bacterial growth.
• Domestic hot and cold water systems – Common in residential, commercial, and healthcare settings.
• Spa pools, fountains, and decorative water features – Frequent aerosol production and warm water environments.
• Stored water tanks and calorifiers – Provide standing water and fluctuating temperatures conducive to legionella.
• Infrequently used outlets – Can lead to stagnant water and bacterial buildup.
• Complex plumbing systems – Increased potential for dead legs and inconsistent temperature control.
• Sites with aerosol generation and temperature variation – Any building type with these features may require mandatory testing.

How Much Does Legionella Water Testing Cost?

In Tyne and Wear, a basic legionella test on a small system with a single water outlet cost starts at around £60–£100, whereas a large building with multiple sampling points and UKAS-accredited lab analysis may cost significantly more.

The pricing is also influenced by how often testing is required, whether monthly, quarterly, or annually, and whether rapid testing or next-day results are needed.

Who Is Responsible For Legionella Testing In A Building?

Legionella testing is the responsibility of employers, landlords, and property managers under the Health and Safety at Work Act, COSHH Regulations, and ACoP L8 guidance. This includes testing water where indicated by a risk assessment.

The responsible person should be competent to manage these tasks or appoint qualified external support. Failure to comply can result in prosecution, fines, or enforcement notices, particularly where there are public access in Tyne and Wear or vulnerable users.

How Often Should Legionella Testing Be Carried Out?

In Tyne and Wear, legionella testing for most hot and cold water systems in commercial or public buildings is required quarterly or annually. Cooling towers and spa pools, due to their higher risk, often require weekly to monthly sampling.

If the risk assessment identifies specific concerns, such as inconsistent temperatures or infrequent use, more frequent testing may be recommended. After major works or prolonged shutdowns, retesting is always advised before reopening to ensure safety.

What Is Involved In The Legionella Water Testing Process?

The legionella testing process includes a site visit, collection of water samples, lab analysis, and a detailed report with recommended actions.

Our team in Tyne and Wear will attend your site to identify relevant outlets and storage systems, then safely collect samples from showers, taps, tanks, or cooling equipment. These samples are submitted to a UKAS-accredited laboratory for microbiological analysis.

In Tyne and Wear, results are typically available within 5–10 working days, or faster for rapid testing clients. We then provide a clear report highlighting any positive results, potential risks, and necessary control measures, including flushing, cleaning, or chemical disinfection.

What Are The Legal Requirements For Legionella Control And Testing?

For optimal legionella testing, the ACoP L8 guidance, developed by the HSE, sets out how duty holders should manage legionella risks, including carrying out regular testing, maintaining written schemes, and documenting monitoring activities.

These requirements apply under broader legislation such as the Health and Safety at Work Act 1974 and COSHH Regulations 2002. Compliance is not optional; it’s a legal expectation and one that is routinely enforced through audits and inspections in Tyne and Wear.

What Happens If Legionella Is Detected In Your Water System?

If legionella is found, we assist clients in Tyne and Wear by initiating system disinfection, isolating affected outlets, and retesting after remediation.

We also review and revise risk assessments and control schemes to prevent recurrence. In some cases, repeated positive results may require permanent system alterations.

Throughout the process, we provide clear guidance, documentation for regulators, and support for reopening or ongoing monitoring.
