Do you need a TM44 air conditioning inspection?
If your building's air-conditioning systems have a combined effective rated output of more than 12kW, yes: the law requires an inspection by an accredited assessor at least every five years, with the report lodged on the national register. Beyond the inspection, regular servicing keeps systems efficient, which feeds directly into your EPC rating and running costs.
- The requirement comes from the Energy Performance of Buildings (England and Wales) Regulations 2012, which cover systems over 12kW and set a maximum five-year interval, as GOV.UK’s air conditioning inspection guidance explains.
- Inspections must be carried out by an accredited air-conditioning energy assessor and the report lodged; you can check for an existing report on Find an energy certificate.
- Failing to have a valid inspection report can attract a fixed penalty, and a new owner or tenant is entitled to be given the report.
- Air conditioning is a major driver of a building's energy use, so servicing and upgrades are one of the quickest routes to a better commercial EPC rating.

What the work involves
A TM44 inspection reviews the systems, their controls, sizing and maintenance records and reports on efficiency and recommended improvements. A servicing contract adds scheduled visits covering filters, refrigerant and F-Gas leak checks, controls and performance. Installs and replacements are scoped, designed and commissioned by certified engineers.
What it delivers
- A lodged TM44 inspection report where required
- Scheduled servicing with records and F-Gas compliance
- Repairs and fault-finding
- Design, supply and installation of new systems
- Advice on efficiency and EPC improvements
Who needs it
- Occupiers and landlords of air-conditioned buildings
- Facilities and office managers
- Owners planning EPC or MEES improvements
- Multi-site operators wanting one contract
Why it matters
- TM44 is a legal requirement over 12kW
- Well-serviced systems use less energy
- Air conditioning directly affects your EPC rating
- Breakdowns are costlier than planned servicing
Air conditioning is where compliance meets your energy bill.
The TM44 inspection is the legal minimum. The real value is in what it tells you: how efficiently your systems run, and which servicing or upgrades will cut running costs and lift your EPC rating, which matters more every year as MEES tightens. One engineer, one plan, both problems handled.
