What is a TM44 inspection?
A TM44 inspection is an energy assessment of the air conditioning serving a building, carried out to the CIBSE TM44 methodology by an accredited air conditioning energy assessor. The assessor records the systems installed, checks whether they are correctly sized for the spaces they serve, reviews controls and maintenance, and produces a formal report with recommendations to cut energy use and running costs.
It is not a pass-or-fail test. The value sits in the report: a clear picture of the cooling assets in your building and a prioritised list of things worth changing.
The legal requirement
Under the Energy Performance of Buildings (England and Wales) Regulations 2012, air conditioning systems with an effective rated output of more than 12kW must be inspected by an accredited energy assessor at least every five years. The report must be lodged on the national register and made available on request.
- • The 12kW figure is the combined output of all systems serving the building
- • Responsibility sits with the person controlling the system
- • Reports must be renewed at least every five years
- • Trading standards enforce it and can issue a penalty
Who needs a TM44 inspection?
Building owners
Responsibility for having a valid inspection report normally sits with the person controlling the system.
Landlords & managing agents
Reports are routinely requested at lease renewal, rent review and disposal.
Facilities managers
Multi-site portfolios need a rolling inspection programme so nothing lapses past five years.
Retail & hospitality operators
Shops, restaurants and hotels pass the 12kW threshold more easily than owners expect.
Offices & professional practices
Multi-floor VRF installations are almost always in scope.
Industrial & logistics sites
Office pods, control rooms and comms rooms combine to exceed the threshold.
What's included in our inspection
- • Inventory of the air conditioning systems serving the building
- • Assessment of system sizing against the spaces being cooled
- • Review of controls, time schedules and set points
- • Check of maintenance records and evidence of servicing
- • Inspection of accessible plant, filters, coils and pipework condition
- • Identification of obvious refrigerant leakage or performance issues
- • Written recommendations to improve efficiency and cut running costs
- • Formal TM44 report lodged on the national register
Why it's worth doing properly
Legal compliance
A valid, lodged report you can produce immediately if it's requested at sale, lease or inspection.
Lower running costs
Recommendations target oversized plant, poor controls and neglected maintenance — the three biggest cost drivers.
Better system life
Issues picked up in the report often prevent avoidable breakdowns and premature plant replacement.
Evidence for ESG reporting
A documented view of your cooling assets and their efficiency supports wider energy and carbon reporting.

Frequently asked questions
What is a TM44 air conditioning inspection?
It's an energy assessment of the air conditioning serving a building, carried out to the CIBSE TM44 methodology by an accredited assessor. It reviews the systems installed, how well they're sized and controlled, and produces recommendations to improve efficiency and reduce running costs.
Is a TM44 inspection a legal requirement?
Yes. Under the Energy Performance of Buildings (England and Wales) Regulations 2012, air conditioning systems with an effective rated output of more than 12kW must be inspected by an accredited energy assessor at least every five years, and the report lodged on the national register.
How is the 12kW threshold worked out?
It's the combined effective rated output of all the air conditioning systems serving the building, not a single unit. Several smaller splits added over the years can easily total more than 12kW.
How often does the inspection need repeating?
At least every five years. If the systems are altered significantly, a new inspection may be needed sooner.
Who is responsible for having the report?
The person who controls the operation of the system — usually the building owner, landlord or the occupier responsible for the plant.
What happens if we don't have a valid report?
Enforcement is carried out by local weights and measures authorities (trading standards) and a penalty can be issued where a valid report isn't held or produced on request.
How long does an inspection take?
A small retail unit or single-floor office is typically a few hours. Larger multi-floor buildings and multi-site portfolios are programmed across several visits.
Do you carry out inspections outside Greater Manchester?
Yes. We're a UK-wide contractor and run national inspection programmes for multi-site clients, with a particular concentration of work across Greater Manchester, Cheshire and Lancashire.
