At TMV Servicing and Maintenance, we specialise in the inspection, testing, and upkeep of Thermostatic Mixing Valves (TMVs) to ensure safe and efficient water temperature regulation.

TMVs are essential for preventing scalding, reducing Legionella bacteria risks, and maintaining compliance with health and safety regulations in hospitals, care homes, schools, hotels, and commercial properties.

Regular servicing helps extend TMV lifespan, prevent failures, and ensure water systems remain safe and compliant.

If you’re looking for professional TMV maintenance in the UK, our certified engineers are ready to assist.

Why is TMV Servicing and Maintenance Important?

Regular TMV servicing and maintenance is crucial for preventing dangerous temperature fluctuations that can cause scalding injuries.

TMV maintenance is legally required in healthcare, educational, and commercial buildings, ensuring compliance with water safety standards.

Thermostatic Mixing Valve servicing helps extend TMV lifespan, reducing blockages, leaks, and system malfunctions that could lead to expensive repairs or replacements.

What does TMV Servicing and Maintenance Include?

Professional TMV servicing and maintenance involves a series of checks to ensure optimal performance and regulatory compliance, such as:

• Temperature testing – Verifies that the TMV maintains a safe and consistent water temperature.
• Failsafe shut-off test – Simulates cold water supply failure to ensure the TMV correctly shuts off hot water, preventing burns.
• Cleaning and descaling – Removes limescale, rust, and debris that can obstruct the valve and affect performance.
• Filter inspection and replacement – Ensures clogged filters do not disrupt water flow or temperature regulation.
• Flow rate testing – Checks for consistent water pressure and proper mixing of hot and cold water.
• Valve calibration and adjustment – Fine-tunes the TMV for accurate temperature control and efficient operation.
• Leak and corrosion check – Inspects seals, components, and pipework for signs of damage, wear, or potential failures.

How much does TMV Servicing and Maintenance Cost?

The average cost of TMV servicing and maintenance is £250 – £300.

The price of TMV servicing and maintenance in the UK typically varies based on several factors, including the number of TMVs on site, the location and ease of access to the valves, the type of premises (such as healthcare, care homes, or commercial buildings), and how frequently servicing is required.

How Often should TMVs be Serviced and Maintained?

TMVs should be serviced every 6 months in high-risk environments such as hospitals, care homes, and schools, where strict temperature control is essential for safety.

In commercial buildings, hotels, and gyms, annual servicing is generally sufficient to ensure consistent water temperature regulation.

Residential properties with TMVs in bathrooms or kitchens should also undergo periodic servicing, especially if there are signs of reduced performance, leaks, or fluctuating water temperatures.

Who Needs TMV Servicing and Maintenance?

TMV servicing and maintenance is a legal requirement for facilities where water temperature control is essential, including:

• Hospitals and care homes – Reduces the risk of scalding and Legionella contamination for vulnerable individuals.
• Schools and nurseries – Protects children from unsafe water temperatures.
• Hotels and gyms – Ensures compliance with water safety regulations in high-usage facilities.
• Commercial buildings – Maintains safe water systems in workplaces and public spaces.
• Residential properties – Keeps TMVs in kitchens and bathrooms functioning efficiently for safe temperature control.
