TM44 Legislation

Are you aware of the current TM44 legislation regarding energy efficiency of air conditioning systems.

Do you have an air conditioning system that is over 12 kw in total?

Do you own or manage a building with Air-Conditioning systems exceeding the 12 kw limit?

If the answer to any of these are yes then a TM44 Air-Conditioning Inspection is required by law.

Why are Air Conditioning Inspections required?

The regulations and requirements relating to air conditioning system inspections for England and Wales have now been in place for over three years, and for a slightly shorter period for Northern Ireland and Scotland. The principle guidance for the inspections is contained in CIBSE TM44. inspections which are carried out for compliance with the EPBD (Energy Performance of Buildings Directive).

Having your Air Conditioning system inspected by an accredited energy assessor is designed to improve efficiency, reduce energy consumption, operating costs and the carbon footprint.

The energy assessor will highlight improvements to the operation of existing systems and show opportunities to replace older, less energy efficient systems or oversized systems with new energy efficient systems.

When are Air Conditioning Inspections required?

All Air-Conditioning systems with a combined output of 12kw or more must be inspected by an energy assessor. The inspections must be no more than five years apart. Systems under five years old are excluded but must be assessed at year five.

The regulations require the first inspection are carried out as follows:

  • For all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when the system was first put into service.

Systems requiring a TM44 inspection:

Only Air-Conditioning systems with an effective rated output of more than 12kW are affected by these regulations. This will include systems consisting of individual units such as 3 x 4kw units whose combined effective rated output is 12kW or more.

There are penalties for not having a report:

Trading Standards are the authority who will police compliance. Failure of compliance can mean fines from £300 per offence (per a building / a unit).

A further penalty can be issued for failure to provide a copy of the air conditioning inspection report when requested to an officer of an enforcement authority within seven days. This is fixed at £200 (per a building / a unit).

Air Control & Development Ltd can now provide the necessary assessments, with all reports being lodged onto the central register.
