TMV2 Testing
Enquire TodayAt ThermoSafe Services, we provide professional TMV2 testing, helping businesses, property managers and organisations ensure their thermostatic mixing valves operate safely and effectively.
Our TMV2 testing services include water temperature checks, valve inspections and performance testing to identify faults, maintain reliable temperature control and reduce the risk of scalding.
We work with schools, residential properties, care facilities and commercial buildings throughout the UK, providing one-off TMV2 testing and planned inspection programmes.
What is TMV2 Testing?
TMV2 testing involves checking the performance of thermostatic mixing valves approved under the TMV2 scheme to ensure they continue to regulate mixed water temperatures correctly.
TMV2-approved valves are primarily designed for domestic and similar applications where controlled hot water temperatures help protect users against scalding.
Over time, scale, debris, worn components and changes in water pressure can affect a valve's ability to maintain the required outlet temperature.
Our TMV2 testing services can include:
Visual inspections: Checking valves and associated connections for leaks, corrosion, damage and signs of deterioration.
Temperature testing: Measuring mixed water temperatures to confirm that the valve delivers water at the intended temperature.
Performance checks: Assessing whether the valve maintains consistent temperature control during operation.
Fail-safe testing: Checking the valve's response to cold water supply interruption where required and appropriate.
Component inspections: Identifying potential problems with filters, strainers, cartridges and other accessible components.
Testing records: Documenting results, identified faults and recommendations for maintenance or replacement.
Testing procedures depend on the valve manufacturer, installation and relevant guidance.
ThermoSafe Services provides TMV2 testing for individual properties and larger facilities with multiple thermostatic mixing valves.
How much does TMV2 Testing Cost?
TMV2 testing typically costs between £80 and £120 per valve, although prices can vary depending on the property, number of valves and testing requirements.
The cost of TMV2 testing depends on several factors:
Number of valves: Testing multiple TMVs during one visit may reduce the cost per valve.
Valve accessibility: Concealed or difficult-to-access valves can increase the time required.
Valve condition: Valves affected by scale, corrosion or other faults may require additional investigation.
Testing requirements: The checks needed can vary depending on the valve type and application.
Additional maintenance: Cleaning, repairs or replacement components may incur additional charges.
ThermoSafe Services can provide a quotation based on the number of TMV2 valves installed and the requirements of your property.
How Often should TMV2 Valves be Tested?
TMV2 testing frequency depends on the valve manufacturer's instructions, the application and the level of risk associated with the outlet.
Annual testing may be suitable for some installations, although more frequent checks may be necessary where users face an increased risk of scalding.
Regular testing is particularly important in properties used by children, elderly people and individuals who may have difficulty responding to excessively hot water.
Testing helps identify temperature fluctuations, reduced valve performance and faults that could affect safe operation.
ThermoSafe Services can help property owners and facilities managers establish suitable TMV2 testing schedules.
How does TMV2 Testing Work?
Our TMV2 testing process focuses on assessing valve condition, measuring outlet temperatures and checking that the thermostatic mixing valve operates correctly.
Initial Inspection: We examine the valve and associated pipework for visible signs of damage, leaks, corrosion or deterioration.
Temperature Measurement: We use suitable temperature measuring equipment to check the mixed water temperature at the outlet.
Performance Testing: We assess whether the valve maintains the intended outlet temperature during normal operation.
Safety Checks: Where appropriate, we check the valve's response to changes or interruptions in the water supply.
Fault Identification: We identify issues that may affect performance and advise whether servicing, adjustment or replacement is required.
Testing Documentation: We record the testing results and provide recommendations for any further work.
The exact testing procedure depends on the valve model, manufacturer guidance and installation requirements.
What Standards Apply to TMV2 Testing?
The TMV2 scheme provides an independent approval framework for thermostatic mixing valves intended for domestic and similar applications.
TMV2-approved valves are assessed against relevant performance requirements, including temperature stability and protection against excessively hot water.
Depending on the valve type, relevant product standards can include:
BS EN 1111: Requirements for thermostatic mixing valves designed for high-pressure applications.
BS EN 1287: Requirements for thermostatic mixing valves designed for low-pressure applications.
TMV2 Scheme Requirements: Additional performance and approval criteria for thermostatic mixing valves intended for domestic use.
These standards primarily relate to valve design, performance and product approval. Routine in-service testing should follow the manufacturer's instructions and applicable guidance for the installation.
ThermoSafe Services provides TMV2 testing to help organisations assess the continued performance of their installed valves and maintain appropriate servicing records.
How Long does TMV2 Testing Take?
TMV2 testing typically takes around 30 to 60 minutes per valve, although the duration depends on accessibility, valve condition and the testing required.
Straightforward temperature and performance checks may take less time, while valves with suspected faults can require additional investigation.
For schools, residential developments and commercial properties with multiple thermostatic mixing valves, the total testing time depends on the number of valves and their locations throughout the building.
ThermoSafe Services can arrange planned TMV2 testing to help minimise disruption to building occupants and normal operations.
TMV2 Testing for Residential and Commercial Properties
ThermoSafe Services provides TMV2 testing for properties in where thermostatic mixing valves are installed to control hot water temperatures.
Our services are suitable for:
Residential properties: Testing TMV2-approved valves installed in bathrooms, showers and other domestic hot water outlets.
Schools and nurseries: Checking appropriate TMV2 installations in facilities used by children and staff.
Residential developments: Supporting landlords, housing providers and property managers responsible for multiple properties.
Commercial buildings: Testing thermostatic mixing valves installed in offices, workplaces and other commercial premises.
Care facilities: Assessing suitable TMV2 installations where required, while recognising that higher-risk healthcare applications may require TMV3-approved valves.
Facilities management companies: Providing testing across individual buildings and multi-site property portfolios.
We offer one-off TMV2 testing visits and planned testing programmes for organisations throughout the UK.
What is the Difference Between TMV2 and TMV3 Testing?
TMV2 and TMV3 are approval schemes for thermostatic mixing valves intended for different applications and levels of risk.
TMV2 testing focuses on checking the continued performance of TMV2-approved valves, which are primarily used in domestic and similar environments.
TMV3 testing applies to valves approved for healthcare applications where users may be particularly vulnerable to scalding.
TMV3-approved valves are subject to more demanding approval requirements and may require additional in-service performance checks depending on the healthcare setting.
ThermoSafe Services provides both TMV2 and TMV3 testing, helping organisations maintain appropriate temperature control across their properties.
Why is Regular TMV2 Testing Important?
Regular TMV2 testing helps identify faults that could prevent thermostatic mixing valves from maintaining the intended water temperature.
Without appropriate checks, scale, debris, worn components and changes in water pressure can affect valve performance.
Planned testing provides several benefits:
Scald prevention: Helps identify temperature control faults that could expose users to excessively hot water.
Consistent water temperatures: Checks whether valves continue to maintain the intended mixed water temperature.
Early fault detection: Identifies performance problems before they lead to complete valve failure.
Reduced maintenance costs: Allows faults to be investigated before more extensive repairs become necessary.
Improved valve reliability: Supports the continued performance of installed thermostatic mixing valves.
Testing records: Provides documentation of completed inspections and any recommended corrective work.
For landlords, schools, property managers and commercial organisations, regular testing also supports the effective management of hot water safety.

Frequently Asked Questions
Is TMV2 Testing a Legal Requirement?
There is no single legal requirement specifying the same TMV2 testing frequency for every property.
However, landlords, employers and building operators may have duties to manage scalding risks and maintain safe hot water systems. Appropriate TMV testing can help support these responsibilities.
What Happens if a TMV2 Valve Fails Testing?
If a TMV2 valve fails testing, further investigation may be required to identify the cause.
Depending on the fault, the valve may need cleaning, adjustment, servicing or replacement before it can operate correctly.
What Temperature should a TMV2 Valve Deliver?
The appropriate outlet temperature depends on the application, valve settings and relevant guidance.
For example, a mixed water temperature of around 41°C may be suitable for certain bathing applications, but there is no single temperature that applies to every TMV2 installation.
Testing should confirm that the valve delivers the intended temperature for its particular use.
Can TMV2 and TMV3 Valves be Tested During the Same Visit?
Yes. Where both types of valve are installed, ThermoSafe Services can arrange TMV2 and TMV3 testing during the same visit, subject to the site's requirements.
Each valve should be assessed using the appropriate procedures for its type and application.
