TM44 Air Conditioning Inspections

If your building has air conditioning systems with a combined output of over 12kW, you are legally required to undertake a TM44 air conditioning inspection every five years. These inspections are a key part of the UK’s energy compliance framework, helping organisations reduce energy consumption, improve system performance, and meet regulatory obligations.

Ensure Compliance and Improve Efficiency with TM44 Inspections

At Arthian, we provide accredited TM44 inspections as part of our wider energy compliance consultancy offering. Whether you manage a single site or a large property portfolio, our expert team ensures your systems are compliant, efficient, and aligned with your sustainability goals.

What Is a TM44 Inspection?

A TM44 inspection is a statutory assessment of air conditioning systems, required under the Energy Performance of Buildings (England and Wales) Regulations. The inspection evaluates the efficiency of your system, identifies faults or areas for improvement, and provides recommendations to reduce energy use and carbon emissions.

Who Needs a TM44 Inspection?

You are required to have a valid TM44 inspection if:

Your building has one or more air conditioning systems with a combined output over 12kW
The system is used for cooling (not just ventilation or heating)
The system has not been inspected in the last five years

Failure to comply can result in enforcement action and fines from local authorities.

What’s Included in a TM44 Inspection?

Our TM44 inspections are carried out by accredited assessors and include:

A full review of system documentation and maintenance records
On-site inspection of air conditioning units and controls
Assessment of system efficiency and sizing
Identification of faults, inefficiencies, or non-compliance
A detailed inspection report with recommendations for improvement

The report is valid for five years and must be made available to enforcement officers upon request.

Frequently Asked Questions (FAQs)

How often do I need a TM44 inspection?
Every five years. If your system has not been inspected within this timeframe, you are at risk of non-compliance.

What happens if I don’t have a valid TM44 report?
You may be fined and required to undertake an inspection immediately. Local authorities are responsible for enforcement.

Can Arthian manage inspections across multiple sites?
Yes. We specialise in supporting organisations with large or complex estates, offering coordinated inspections and centralised reporting.

Do I need to act on the recommendations in the report?
While not mandatory, acting on recommendations can lead to significant energy and cost savings. We can support implementation through our consultancy services.
