TM44 Air Conditioning Inspection 

The Energy Performance of Buildings Directive (EPBD) requires that all air conditioning systems with an effective rated output of more than 12 kW must be inspected every 5 years by an energy assessor.  Building managers have a statutory obligation to ensure these air conditioning inspections are undertaken – or risk a Penalty Charge Notice.


ESOS Energy can undertake your compliance inspection and provide useful recommendations for the efficient operation and maintenance of your air conditioning system.  The purpose of the inspection and the report is to ensure that building managers are provided with information regarding the effectiveness of the system that they control, as well as advice on how the energy efficiency of these systems can be improved.

Our qualified assessor will examine the refrigeration, air movement and controls of the system - and also review maintenance reports to help us to better understand the system.  We will then suggest whether your system is suitably sized for operational requirement, cooling loads and treated spaces and provide you with recommendations where the performance of the system might be enhanced.


Our reports contain advice with simple low or no cost measures and also guidance for the ongoing management of the systems.  You don’t have to follow the recommendations, but you may save money if you do so.



What does a TM44 inspection cover?


  • the current efficiency of your equipment

  • suggestions for improving the efficiency of your equipment

  • any faults and suggested actions

  • how to reduce your air conditioning use


What happens if I don't comply?


Failing to have your air-conditioning system inspected or failing to have a copy of the inspection report will result in enforcement action and the issue of a Penalty Charge Notice.
