TMV Servicing
Contact UsAt ThermoSafe Services, we provide professional TMV servicing, helping businesses and organisations maintain safe, reliable hot water temperature control.
Our thermostatic mixing valve servicing includes inspections, temperature testing, performance checks and cleaning to identify faults, reduce the risk of scalding and keep valves operating correctly.
We work with schools, hospitals, care homes, healthcare facilities and commercial properties throughout the UK, providing one-off TMV servicing and planned maintenance programmes.
What is TMV Servicing?
TMV servicing involves inspecting, testing and maintaining thermostatic mixing valves to ensure they continue to regulate hot water temperatures safely and effectively.
Thermostatic mixing valves blend hot and cold water to deliver water at a controlled outlet temperature. Over time, scale, debris, worn components and changes in water pressure can affect their performance.
Regular servicing helps identify these issues before they lead to valve failure or increase the risk of scalding.
Our TMV servicing can include:
Visual inspections: Checking thermostatic mixing valves for leaks, corrosion, damage and signs of wear.
Temperature testing: Measuring mixed water temperatures to confirm that valves deliver water at the required outlet temperature.
Performance testing: Checking valve operation and its response to changes in water supply conditions.
Cleaning and descaling: Removing scale, sediment and debris from accessible components where required.
Component inspections: Checking filters, strainers, cartridges and seals for signs of deterioration.
Service reporting: Recording testing results, identified faults and recommendations for further maintenance.
We service TMV2 and TMV3-approved valves, helping property owners and facilities managers maintain effective temperature control.
How much does TMV Servicing Cost?
TMV servicing typically costs between £100 and £200 per valve, depending on the work required, although prices vary between providers and properties.
The cost of TMV servicing in depends on several factors:
Number of valves: Servicing multiple TMVs during one visit may reduce the cost per valve.
Valve condition: Valves affected by scale, corrosion or damaged components may require additional work.
Accessibility: Concealed or difficult-to-access valves can increase labour time.
Valve type: TMV2 and TMV3-approved valves may have different servicing and testing requirements.
Replacement parts: Faulty cartridges, filters, seals and other components may increase the overall cost.
ThermoSafe Services can provide a quotation based on the number of valves, their condition and the servicing requirements of your property.
How Often should TMVs be Serviced?
TMV servicing frequency depends on the type of valve, its application, manufacturer recommendations and the level of risk associated with the outlet.
Annual servicing may be appropriate for some installations, while hospitals, care homes and other higher-risk environments can require more frequent checks.
In healthcare settings, TMV3-approved valves are subject to specific inspection and performance testing requirements. The appropriate schedule should follow relevant healthcare guidance and site-specific risk assessments.
Regular servicing helps identify temperature fluctuations, worn components, scale accumulation and other faults that could affect valve performance.
ThermoSafe Services can help organisations establish suitable servicing schedules for their thermostatic mixing valves.
How does TMV Servicing Work?
Our TMV servicing process involves inspecting, testing and maintaining thermostatic mixing valves to confirm that they operate correctly.
Initial Inspection: We examine each valve for visible damage, leaks, corrosion and signs of deterioration.
Temperature Testing: We measure the mixed water temperature and assess whether the valve maintains the required outlet temperature.
Performance Checks: We carry out appropriate functional tests to identify problems with temperature regulation and valve operation.
Cleaning and Servicing: Where necessary, we clean accessible components, remove debris and inspect parts that may require replacement.
Final Testing: We check the valve's performance following servicing to establish whether it is operating correctly.
Service Documentation: We record the work completed, testing results and any recommendations for further maintenance or replacement.
The exact servicing procedures depend on the valve manufacturer, model, condition and application.
How Long does TMV Servicing Take?
TMV servicing typically takes around 30 to 60 minutes per valve, although the duration depends on the valve's condition, accessibility and the work required.
Routine temperature testing and inspections may take less time than servicing that involves dismantling components, removing scale or replacing faulty parts.
For larger facilities, including hospitals, schools and commercial buildings, the total servicing time will depend on the number of valves and their locations throughout the property.
ThermoSafe Services can arrange planned TMV servicing to help minimise disruption to normal building operations.

What is the Difference Between TMV2 and TMV3 Servicing?
TMV2 and TMV3 are approval schemes for thermostatic mixing valves designed for different applications and levels of risk.
TMV2-approved valves are primarily used in domestic and similar environments where controlled hot water temperatures help reduce the risk of scalding.
TMV3-approved valves are intended for healthcare applications, including hospitals and care environments where users may be particularly vulnerable to hot water injuries.
Both types of valves require appropriate inspection and maintenance to ensure continued performance.
However, TMV3 servicing may involve additional testing requirements and more frequent checks depending on the healthcare setting and applicable guidance.
ThermoSafe Services provides servicing for both TMV2 and TMV3-approved valves.
Why is Regular TMV Servicing Important?
Regular TMV servicing helps maintain reliable water temperature control and reduces the likelihood of unexpected valve failures.
Without servicing, thermostatic mixing valves can become affected by scale, debris, worn cartridges and other mechanical faults. These problems can prevent valves from regulating mixed water temperatures correctly.
Planned servicing provides several benefits:
Scald prevention: Helps identify faults that could result in excessively hot water reaching an outlet.
Reliable temperature control: Checks that valves continue to maintain the intended mixed water temperature.
Early fault detection: Identifies damaged or deteriorating components before further problems develop.
Reduced breakdowns: Allows maintenance issues to be addressed before they cause unexpected failures.
Longer valve lifespan: Appropriate servicing can help reduce unnecessary wear and premature replacement.
Maintenance records: Provides documentation of completed inspections, testing and servicing.
For schools, hospitals, care homes and commercial properties, regular TMV servicing also supports effective water safety management.

Frequently Asked Questions
What does TMV Servicing Include?
TMV servicing typically includes visual inspections, outlet temperature testing, performance checks and cleaning where required.
The work may also involve checking filters, strainers, cartridges and other components for wear or damage.
Is TMV Servicing a Legal Requirement?
There is no single legal requirement specifying an identical servicing interval for every thermostatic mixing valve.
However, employers, building operators and those responsible for water systems may have legal duties to manage scalding risks and maintain safe facilities. Appropriate TMV inspection and maintenance can form part of meeting those duties.
Can a Faulty TMV be Serviced?
Some faulty TMVs can be restored through cleaning, descaling or replacing worn components.
However, valves that are extensively damaged, obsolete or unable to maintain the required outlet temperature may need replacing.
What Happens if a TMV is Not Serviced?
Without regular servicing, scale, debris and component wear can affect a thermostatic mixing valve's ability to regulate water temperature.
This can result in inconsistent outlet temperatures, reduced performance and an increased risk of scalding.
Does TMV Servicing Include TMV3 Testing?
TMV3 performance checks may form part of servicing where TMV3-approved valves are installed.
The testing required depends on the valve, its application and the relevant healthcare guidance.
