TM44 Inspections

Ensuring our clients are legally compliant

Remaining compliant

Anyone with air conditioning on their premises has a legal requirement to ensure that their systems are running correctly.

From January 2013 a mandatory requirement was put in place by the EPBD and has rolled out across the UK.

Evergreen's TM44 Inspections

A trained member of our team will carry out a full inspection and formulate all of the findings and results into official reports. These are then formally submitted to demonstrate our client is legally compliant.

Inspected Systems

Inspections are to be carried out on units with a cooling capacity of over 12kw. Inspections will be carried out to a TM44 standard set out by the Chartered Institute of Building Services.

Inspection Frequency

If your air conditioning system is over 12kW and installed from the start of 2008 it is mandatory that it must be inspected within five years of installation, and then every five years from the date of the first inspection.

Benefits of a TM44 Inspection

The inspection may identify issues that can be resolved to ensure our clients systems are running as efficiently and cost effectively as they can.

We encourage our clients to be as environmentally friendly as possible and our inspections ensure that they are. We help and guild them to reduce energy use and emissions.
The result is that our clients get the best out of their systems and maintain a perfect environment whilst ensuring they are compliant with the law.
