What is a TM44 Air Conditioning Inspection?

First introduced in 2011 by the Energy Performance of Buildings Directive (EPBD), the TM44 regulation inspection is the process in which an accredited inspector comes out to inspect your air conditioning system. As part of the inspection, the assessor will review the efficiency of your system, check for faults, and advise you on how you can make it more efficient and reduce the costs involved in running it. You will receive a full report following the inspection that details findings, faults, and recommendations.

Do I need a TM44?

Building owners and managers with control of air-conditioning systems with an effective rated output of more than 12kW are legally required to ensure compliance with the regulations. This includes systems consisting of individual units which are less than 12kW but whose combined effective rated output is more than 12kW. This applies to both commercial and residential properties, and it is the responsibility of the property owner to arrange the inspection. These inspections must be carried out every five years to remain compliant.


The penalty for failing to have a valid TM44 Air Conditioning Inspection report is fixed at £300


What does a TM44 inspection cover?

A TM44 inspection examines the refrigeration, air and water movement equipment that are part of the air conditioning system and associated controls. For the compliance certificate/report, only sampling of the units is required. However, with Briar a full report on all the units can be provided.

The report will also highlight opportunities such as:

  • Improvement to operation
  • Improvements to replace less efficient systems
  • Replacement of oversized systems Our TM44 inspections will provide a return on investment if the recommendations are acted upon.

How do our TM44 reports differ from other providers?

A TM44 certificate and report is required for compliance purposes. However, we believe that these reports should provide more, something that provides a return on your investment. In addition to the compliance format reports, we can provide:

  • Energy data usage and refrigerant quantities for each system on site
  • A projection of the energy and operating cost of each system and for the whole site
  • Energy costs and savings of implementing the assessors site recommendations
  • The Energy Efficiency Rating (EER) is provided for each system
  • Assessment of the actual occupancy hours to the settings to show savings
  • Asset list for all Air Conditioning equipment and F-gas logbook
  • Identification of inefficient systems for investment
