What Is an Air Conditioning Report (TM44)
An Air Conditioning Report, commonly known as a TM44 report, is a legally required inspection for UK commercial buildings with air conditioning systems that have an effective rated output exceeding 12kW.
TM44 inspections were introduced under the Energy Performance of Buildings Directive and are designed to assess how efficiently an air conditioning system operates, how well it is maintained, and whether it is correctly controlled.
The inspection must be carried out by a registered and accredited assessor, with reports required every five years to remain compliant.
Who Needs a TM44 Air Conditioning Inspection
TM44 inspections apply to a wide range of commercial properties, including:
- Office buildings and business parks
- Retail units and shopping centres
- Hotels and leisure facilities
- Warehouses and logistics sites
- Healthcare and education buildings
- Public sector premises
- Large multi split or VRF systems
If multiple air conditioning units together exceed 12kW, a TM44 inspection is still required, even if individual units are smaller.
What Our TM44 Air Conditioning Reports Cover
Visual Inspection of Equipment
Our assessors carry out a detailed visual inspection of key system components, including:
- Chillers and condenser units
- Air handling units
- Indoor and outdoor equipment
- Pipework and insulation
- Evidence of maintenance and condition
Review of Controls and Settings
We assess how effectively your system is controlled, including:
- Thermostat settings
- Zoning and time controls
- Automatic shut off features
- Integration with building management systems
System Sizing & Performance
The inspection evaluates whether your system is appropriately sized for the building’s cooling load, identifying:
- Oversized or undersized systems
- Inefficient operation
- Opportunities to improve performance
Building Factors Affecting Efficiency
We consider building elements that influence cooling demand, such as:
- Glazing and solar gain
- Lighting heat output
- Occupancy patterns
- Operating hours
What You Receive After a TM44 Inspection
Following your inspection, EPC-Hub provides:
- Air Conditioning Inspection Report (AC REPORT) detailing findings and efficiency observations
- Air Conditioning Inspection Certificate (AC CERT) confirming compliance
- Clear recommendations to reduce energy use and running costs
- Guidance on maintenance and control improvements
These documents must be retained and made available if requested by enforcement authorities.
TM44 Compliance & Penalties
Failure to hold a valid TM44 report can result in enforcement action by Trading Standards.
Current penalties are typically around £300 per offence, with the potential for higher fines if non-compliance continues.
Regular inspections not only ensure legal compliance but also help businesses identify inefficiencies that increase electricity consumption and operational costs.
TM44 Reports & Wider Energy Compliance
TM44 inspections play an important role in a building’s overall energy performance strategy. Inefficient air conditioning systems can negatively affect EPC outcomes and ongoing energy costs.
