TMV assessments in Northern Ireland
TMV assessments across Northern Ireland.
What tmv assessments involves
A thermostatic mixing valve blends hot and cold water to limit the temperature delivered at a tap or shower. A TMV assessment checks whether that protection is working, including the valve's response to a loss of cold supply where a suitable test can be carried out safely.
These checks are particularly relevant in care settings, accessible bathrooms and premises used by children or people who cannot quickly move away from hot water. Book TMV assessments at a set price for the agreed valves; a specialist records their performance and identifies any further servicing or replacement needed.
How tmv assessments works with us
Valve identification
The specialist matches each accessible valve to its outlet and available installation or maintenance information.
Temperature measurement
Supply and mixed-water temperatures are measured where accessible to assess delivery against the applicable settings.
Safety response
Where safe and practicable, the specialist tests the valve's response to cold-supply isolation using the appropriate procedure.
Results schedule
Each assessed valve receives a recorded result with any limitations, faults and recommended follow-up actions.
When might these checks apply?
- Mixed water becomes unexpectedly hot during normal use.
- Shower temperature changes sharply when another outlet is opened.
- A valve has no identifiable commissioning or test record.
- The planned checking date has passed without recorded results.
- A bathroom has been altered or a mixing valve recently replaced.

Looking after it afterwards
- Follow the report’s action plan and record completed work, outstanding tasks and responsible people.
- Keep the water system description and outlet register updated after plumbing alterations.
- Arrange cleaning and descaling of showerheads and hoses according to the control scheme.
- Flush infrequently used outlets as specified in the control scheme, recording completion and taking precautions to limit aerosol exposure.
| Check | How often |
|---|---|
| Inspect accessible storage tanks for contamination, lid condition and insulation | At the interval specified in the control scheme |
| Measure and record temperatures at designated monitoring outlets | According to the written temperature monitoring schedule |
| Review control records, outstanding actions and changes to water system use | At planned reviews and following relevant system changes |

Scald protection without overlooking water hygiene
Mixed temperature is not storage temperature
Reducing the temperature at the point of use does not mean the entire hot water system should run cooler. The specialist considers the valve's scald protection alongside upstream temperatures and the premises' legionella controls.
The right test for the valve
Valve type, manufacturer instructions and the setting determine the appropriate checks. Where isolation and access permit, the specialist tests the safety response rather than relying solely on a comfortable outlet temperature.
Assessment and servicing are different
Performance checks can reveal an unstable temperature or failed safety response, but they do not automatically include dismantling, descaling or replacing components. The booking scope establishes what is covered, and the findings identify further work where needed.
