What does an inspection entail?
A TM44 inspection is a mandatory assessment of air conditioning systems with a combined cooling capacity of over 12kW. The inspection reviews the efficiency, condition, and control of your system and provides recommendations to reduce energy use and carbon emissions.
Regulations Behind Inspections
TM44 air conditioning inspections are a legal requirement in the UK under the Energy Performance of Buildings (England and Wales) Regulations 2012 and, in Scotland, the Energy Performance of Buildings (Scotland) Regulations 2008. These regulations implement the Energy Performance of Buildings Directive (EPBD), which aims to improve building energy efficiency and reduce carbon emissions across Europe.
Governing Body and Technical Authority
CIBSE TM44 is the official technical guidance that sets out how air conditioning inspections must be carried out to comply with UK regulations. While TM44 itself is not legislation, it is the recognised compliance route referenced by the regulations. Air conditioning inspections must be completed in accordance with this guidance and renewed every 5 years.
CIBSE guidance sets out:
- The inspection scope and methodology
- Required competence of assessors – inspections must be carried out by an accredited TM44 energy assessor
- Reporting and lodgement requirements – the inspection report must be lodged on the official government register
- Minimum standards for compliance
- An additional report sets out the executive summary and details of the assessment and the systems covered.
