What is a TM44 Inspection?
A TM44 inspection is a detailed evaluation of a building’s air conditioning system, conducted by a certified assessor, such as ACOC. In addition to inspecting the system, the assessor reviews how the system is used, maintained, and serviced. The resulting report provides actionable recommendations to improve energy efficiency, reduce the carbon footprint, and lower operating costs.
The Report Also Covers
Faults: Identification of issues and suggested corrective actions.
System Controls: Evaluation of control adequacy and improvement recommendations.
Control Settings: Suggestions for optimization.
System Size: Assessment of a system capacity versus cooling demand with improvement recommendations
Summary of Findings: Key recommendations for better performance.
Equipment Inspection: Examination of air handling units and associated areas.
Building Factors: Consideration of elements affecting system efficiency, such as excessive solar gains (glazing/blinds), interactions with heating systems, and lighting systems.Faults: Identification of issues and suggested corrective actions.

-
TM44 inspections are legally mandated for buildings with a combined cooling capacity of 12kW or more. Business owners of such premises are required to ensure compliance, with potential fines for failing to meet the requirements.
-
TM44 regulations became a legal requirement in 2011 under the Energy Performance of Buildings Directive (EPBD), aimed at improving the energy efficiency of UK buildings.
-
Responsibility for ensuring compliance lies with the person or entity in control of the air conditioning system. For example, in a serviced office, if a tenant only operates the thermostat, responsibility would fall on the building manager or the party managing the system.
-
TM44 inspections must be carried out every five years by a qualified Air Conditioning System Assessor such as ACOC
-
TM44 air conditioning energy assessments are a mandatory legal requirement for all domestic and non-domestic buildings with comfort cooling systems that have a combined output of 12kW or more. Non-compliance can lead to significant financial and reputational consequences, including:
Fixed Penalties: Local authorities can impose a fixed penalty of £300 per building for non-compliance.
Recurring Fines: This fine can be issued weekly until a valid TM44 certificate is obtained, resulting in potentially unlimited financial penalties.
Accreditation Impact: Non-compliance can affect business certifications such as ISO standards, potentially harming a company’s credibility and operational standing.
Ensuring timely TM44 assessments is crucial to avoid these penalties and maintain compliance with legal and industry standards.
