TM44 Inspections – Air Conditioning Systems Compliance

TM44 Inspections - Air Conditioning Systems Compliance

Certified air conditioning inspectors delivering TM44 guidance and offering insights to improve efficiency and reduce emissions

What is a TM44 Air Conditioning System Inspection? 

If you have an air conditioning system with a cooling capacity of 12kW or more in your building, you are legally required to have a valid air conditioning inspection report and a certificate in place. 

Our thorough air conditioning inspection and reporting service is delivered by our team of accredited energy assessors ensuring you remain compliant with the TM44 guidelines. 

Common issues found during a TM44 inspection

Based on our many years of experience there are a number of common issues that are identified during an air conditioning inspection:

  • Poor Maintenance: Dirty filters, blocked coils, and inadequate maintenance affect efficiency.
  • Incorrect Settings: Inappropriate temperature settings or faulty controls.
  • Leakages: Refrigerant leaks impact performance.
  • Insufficient Insulation: Poorly insulated ducts and pipework lead to energy loss.
  • Obsolete Systems: Older systems may not meet modern efficiency standards.

Addressing these issues through regular inspections enhances energy efficiency, reduces costs, and prolongs the lifespan of your air conditioning system.

8 Steps to TM44 Inspections

  • Inspection Process:
    • Select an Accredited Assessor: Hire an accredited air conditioning energy assessor to conduct the inspection. They should be registered with an approved certification body. 
    • Data Collection: The assessor gathers information about the system, including its type, capacity, age, and usage patterns.
    • Visual Inspection: The assessor completes a TM44 survey to examines the components, controls, and maintenance records.
    • TM44 Site Survey: The assessor inspects the physical installation, including pipework, ducts, and insulation.
    • Assessment of Efficiency: The assessor calculates the system’s energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER).
    • Recommendations: Based on the findings, the TM44 assessor provides recommendations for improvements.
    • Maintain Records: Keep records of inspections, recommendations, and any actions taken.
    • Display TM44 Certificate: Display the TM44 certificate in a visible location.

These benefits highlight the importance of TM44 inspections not only for legal and environmental reasons but also for financial and operational efficiency.


  • It is a legal requirement under the EU Energy Performance of Buildings Directive (EPBD) to ensure that air conditioning inspections are carried out every 5 years and they are conducted by qualified and accredited air conditioning inspectors 
  • It is mandatory for all companies operating an ISO14001 certified management system 
  • Buildings with an air conditioning system over 12kW must have a valid TM44 air conditioning report 
  • The recommendations part of the report can save money by reducing energy consumption and maintenance cost 
  • Air conditioning reports help you enhance your company’s green credentials. 
  • It is a legal requirement under the EU Energy Performance of Buildings Directive (EPBD) to renew your air conditioning inspection compliance every 5 years 
  • Only systems with an output of 12kW are affected by the regulations 
  • This includes where individual units are less than 12kW, but the combined output across all the units is 12kW or more 
  • The combined output would include where multiple units within a building are controlled by a single person, so are considered a single air conditioning system 
  • An air conditioning assessment must be carried out by an accredited energy assessor. 

If you do not get your air conditioning inspected every five years, you will be fined a minimum of £300 which can be repeated weekly until you have a valid certificate in place. There will be a further £200 fine every time you fail to provide a copy of the report to an enforcement authority such as a Trading Standard Officer (TSO) within seven days.

An inspection of the system should take place every 5-years. If you fail to have your air conditioning inspected, you can receive a fine of £300.
