At TMV Maintenance, we specialise in inspecting, cleaning, and testing Thermostatic Mixing Valves (TMVs) to ensure safe water temperatures, prevent scalding risks, and maintain compliance with safety regulations.

Regular TMV servicing is essential for healthcare facilities, schools, care homes, hotels, and commercial buildings, where temperature-controlled water systems are required to protect users from burns and bacterial growth.

Our certified engineers ensure that your TMVs are functioning correctly, adjusted to safety standards, and free from blockages or malfunctions. If you’re looking for professional TMV maintenance in the UK, we’re here to help.

Why is TMV Maintenance Important?

Proper TMV maintenance prevents scalding risks, as the valve precisely controls hot and cold water mixing. It also plays a vital role in Legionella prevention, as unchecked valves can lead to stagnant or warm water conditions that promote bacterial growth.

Compliance with health and safety regulations is mandatory in settings such as hospitals, nursing homes, schools, and commercial buildings, where temperature-regulated water is essential.

Routine maintenance extends the lifespan of TMVs, preventing blockages, limescale buildup, and unnecessary repairs.

What does TMV Maintenance Include?

A comprehensive TMV maintenance service consists of the following steps:

• Temperature testing – Verifies that water temperatures remain within safe limits.
• Cleaning and descaling – Removes limescale and debris to prevent blockages.
• Performance testing – Checks the valve’s response time and flow rate for reliable operation.
• Valve adjustment – Ensures the correct mixing of hot and cold water, if necessary.
• Inspection of internal components – Examines seals, filters, and thermostatic elements to ensure all parts are in working condition.

How much does TMV Maintenance Cost?

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

The cost of Thermostatic Mixing Valve maintenance varies depending on the number of TMVs to be services, the access, the types and manufacturer of the TMV and the service fee.

How Often should TMVs be Serviced?

TMV servicing for healthcare settings, care homes, and schools requires servicing every 6 months due to higher risk factors.

For commercial buildings, hotels, and gyms, servicing is typically required every 12 months to maintain compliance and efficiency.

Residential properties with TMVs in bathrooms or kitchens may require less frequent servicing, but periodic checks ensure consistent water safety.

• Hospitals and nursing homes – Protects vulnerable individuals from scalding hazards.
