DO YOU NEED A TM44?

A TM44 inspection is required for any air conditioning system that has a combined effective rated output of more than 12kW.

You can find this information on the rating plate attached to your system, in its operating manual, or on the manufacturer’s website.

It’s important to note that the 12kW rule does not only apply to single large scale systems, but also to multiple smaller systems that have a combined output of 12kW or more.

The Red Tape

Is TM44 a Legal Requirement?

TM44 inspections are mandatory, though there is no legal obligation to follow any of the recommendations we lay out in your report. 

To stay fully compliant, the person who controls the operation of a qualifying air conditioning system must:

  • Ensure TM44 inspections are done in accordance with the requirements and timetable of the regulations.

  • Keep the most recent TM44 inspection report provided by an accredited energy assessor. 

  • Hand over any TM44 inspection reports to the new system operator should this change.

In the event that operation responsibilities are handed over and an inspection report is not passed on, the new operator must arrange for a TM44 within three months.

How often is a TM44 required?

A TM44 inspection is a mandatory requirement that must be carried out no more than five years after the last. In line with the EPB Regulations, the initial inspection of a qualifying system must meet the following >>>

  • For all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when the system was first put into service.

  • For other air conditioning systems, where the effective rated output is more than 250kW, the first inspection must have taken place by 4 January 2009.

  • For other air conditioning systems, where the effective rated output is more than 12kW, the first inspection must have taken place by 4 January 2011.

A TM44 with Green Assess

A TM44 inspection produces a comprehenseive report that focuses on the energy efficiency of your air conditioning system and guidance on how this can be improved. 

To complete a TM44 inspection, an accredited energy assessor like Green Assess will visually inspect your AC system and its controls.

We will also evaluate how effective the system is for the size of the area that it serves. From this inspection, we will produce a report complete with the following information:

  • The current efficiency of the system

  • The suitability of the installed controls and control settings

  • Any obvious faults observed

  • The effectiveness of equipment maintenance

  • The type of refrigerant used, and whether the quantity requires regular F-Gas leakage tests

It will also include any recommendations for efficiency improvements. These could be anything from simple changes to your control settings or a complete system upgrade. Whilst you are not legally obliged to follow these recommendations, there are several benefits to doing so:

  • Reduced energy consumption

  • Lower carbon emissions

  • Decreased running costs

  • Increased system longevity
