TM44 Air Conditioning Inspections (ACI)
TM44 Air Conditioning Inspection (ACI) Reports are a legal requirement under the Energy Performance of Buildings (England and Wales) Regulations for all air-conditioning systems with an effective rated output of 12kW or more. The inspection must be carried out at least every five years by an accredited energy assessor and applies to a wide range of non-domestic buildings, including offices, retail, industrial and mixed-use developments. Failure to hold a valid TM44 report can result in enforcement action and financial penalties by local authorities.
TM44 inspections are categorised by system complexity. Level 3 inspections apply to simpler air-conditioning systems, typically split or multi-split installations serving single or limited zones. Level 4 inspections are required for more complex systems, such as centralised plant, VRF/VRV systems, chilled water systems and buildings with multiple air-handling units and controls. Both inspection levels assess system efficiency, sizing, controls, maintenance practices and opportunities to reduce energy consumption and carbon emissions, with Level 4 requiring a more detailed and holistic review of the system and building interaction.

How We Can Help
TM44 Air Conditioning Inspections are a statutory requirement every 5 years for buildings with air-conditioning systems over 12kW. If requested by an enforcement authority, a valid TM44 report must be produced promptly, and non-compliance can result in financial penalties and further enforcement action. Many landlords, managing agents and occupiers are caught out by expired or missing reports, particularly at lease events, audits or compliance reviews.
Our qualified and accredited assessors ensure your compliance, carrying out TM44 Level 3 and Level 4 inspections in line with CIBSE guidance and current regulations. Beyond compliance, we also provide practical advice to improve system efficiency, reduce energy use and support wider energy performance and MEES strategies.
