Understanding TM44
What is a TM44 inspection?
An energy assessment of air-conditioning equipment, controls and operation. The report records findings and opportunities to improve energy performance.
Is it the same as a service?
No. Maintenance, repairs and refrigerant checks remain separate from the energy assessment. A servicing record does not replace a required TM44 report.
Who carries out the inspection?
An accredited air-conditioning energy assessor carries out the assessment and produces the report.
Does an EPC cover my air conditioning?
An EPC is a different assessment. It does not replace an air-conditioning inspection where one is required.
Your building and systems
Does the 12kW threshold apply to one unit?
The combined effective rated output matters. Multiple smaller units under the same control can count together, so do not judge scope only from the size of an individual indoor unit.
What if I do not know the cooling capacity?
Share an asset list, equipment model numbers or photographs if available. The scope can be clarified before booking.
How often should systems be inspected?
For systems in scope, inspections must be no more than five years apart. Use the inspection date on your previous report when planning the next one.
What if I cannot find the previous report?
Tell us when you enquire and provide the property details. Do not assume that a missing report means no inspection was needed.
We rent the premises. Who arranges it?
Responsibility depends on who controls the system. Clarify the arrangements with the landlord or managing agent, especially where plant is shared. Refer to the official guidance if responsibility is unclear.
Booking and costs
How much will my inspection cost?
The quote depends on the systems, access, complexity and number of sites. See the pricing page for the information that helps define the scope.
Can I request a quote without an asset list?
Yes. A postcode, building type and the information you have are enough to start an enquiry. Further details may be needed to confirm the quote.
Can you guarantee a date or turnaround?
Appointment availability and reporting times are confirmed during scoping. Tell us about any deadline before booking so it can be considered.
Can you inspect several properties?
Yes. Include the number of sites and their locations in your enquiry. Each property’s equipment, access and existing inspection date should be recorded separately.
The visit and report
Do I need to be at the property?
A suitable site contact should be available to help with access and explain the systems and building use. Confirm the arrangements before the visit.
What records should I prepare?
A previous report, equipment schedule, maintenance information and operating schedules are helpful. Let us know if records are incomplete.
Will the visit disrupt the building?
Access needs depend on the equipment and location. Discuss occupied areas, restricted access and operational constraints when agreeing the visit.
What happens after the visit?
The assessor completes the assessment and lodges the report. Keep the report with your building records and share relevant findings with the people responsible for the systems.
Must I carry out every recommendation?
The government guidance says you do not have to follow the report’s recommendations. They can still help you assess opportunities to improve efficiency. Other maintenance or legal duties remain separate.
