Do you need to comply?

Since 4th January 2011, it is now a legal requirement for any buildings with over 12kW of total cooling to have a TM44 Air Conditioning Inspection Survey and Report carried out by an Accredited Air Conditioning Inspector and for this report to be lodged with the government's Non-Domestic Energy Performance Certificate Register (Landmark).

If you're not sure if you qualify, if you have more than 1000 sq ft (93 m2) of air conditioned floorspace, then it is highly likely that you will need to have an inspection.


The implementation dates have now passed, so any building that does not possess this certificate is operating outside the law and is non-compliant with current legislation.

Trading standards are also becoming more proactive and clamping down on non-compliant owners and operators.
