TM44 Inspection

The Energy Performance of Buildings Directive, (the EPBD), passed legislation throughout Europe stating that property owners / managers must conduct regular inspections of air conditioning systems that have an output of more than 12kW. Such inspection of air conditioning systems, as per CIBSE guidelines, has been termed a TM44 inspection. By conducting regular TM44 inspections, organisations ensure compliance with EPBD regulations, whilst improving energy efficiency of their air conditioning system.

A TM44 inspection should be carried out every five years by an accredited energy assessor. Failure to do so will lead to a fine of £300. The assessor will inspect systems, how they are being used, as well as their service and maintenance records. A TM44 inspection will carry a fee.

  • Ensuring that Air Conditioning Inspection Reports and Certificates are recorded correctly on the Government’s database.

Who can conduct a TM44 air conditioning inspection?

TM44 inspections must be conducted by an accredited energy assessor. There are two distinct categories of air conditioning units, the first is ‘Level 3’ which includes simple package cooling systems such as split, multi-split and variable refrigerant flow (VRF) units. The second category is ‘Level 4’ which includes complex centralised systems such as VRF units that serve space also shared by a mechanical air supply system. Level 4 accredited inspectors can assess both level 3 and level 4 units, whilst level 3 inspectors are restricted to level 3 assessments.
